It is possible to provide customized learning information through individual one-to-one guidance and to improve student learning efficiency by providing the student's selection among a plurality of set commentary contents and the commentary contents considering the student's learning level.

In the description with reference to FIGS. 2 and 3 above, steps S210 to S330 may be further divided into additional steps or combined into fewer steps, according to an embodiment of the present invention. Also, some steps may be omitted if necessary, and the order of steps may be changed.

Meanwhile, as mentioned above, the present system 10 may include the present server 100 and the student terminal 200 . This server 100 may provide lecture contents. At least some of the functions (contents) described for the server 100 in the present invention may be performed in the student terminal 200 or vice versa.

When a specific unit title in the unit title item is selected from the lecture enrollment screen, the student terminal 200 outputs lecture contents corresponding to the selected specific unit title in conjunction with the server 100, and lecture contents corresponding to the specific unit title. When the output of is finished, a problem solving process is performed for one or more problems related to a specific chapter title in conjunction with the server 100, and when an incorrect problem is selected in the problem solving process for one or more problems, the server 100 ), any one of a plurality of step-by-step commentary contents related to the wrong problem (eg, first-step commentary content, that is, commentary guide content) can be output (displayed) on the screen of the student terminal 200. . Through this, the student terminal 200 can provide any one of the commentary contents to the student who is the holder of the student terminal 200 .

As an example, as shown in FIG. 5 , when a student (first student) who is the holder of the student terminal 200 selects the property item 510 of a natural number as a specific unit title, the student terminal 200 (in particular, the student terminal) My control unit) outputs (displays) the first lecture content 600 on the screen of the student terminal 200 as lecture content corresponding to the specific unit title item (ie, the property item 510 of natural numbers) selected by the student. can In this case, the first lecture content 600 may be, for example, lecture content including first to third math problems as shown in FIG. 6 . In the present invention, as an example, three mathematical problems are included in the contents of the first lecture, but this is only an example to help understanding of the present invention, and is not limited thereto, and the number of problems, etc. It can be set and changed in various ways depending on the level, academic achievement, etc.

When the output of the first lecture contents to the student terminal 200 is finished (ie, when the output of the first lecture contents on the screen of the student terminal is completed), the student (first student) displays a plurality of contents in the first lecture contents. Problem solving (problem solving process) may be performed on the problem (which is, for example, a plurality of math problems, meaning first to third math problems). At this time, when student answer information for each of the plurality of questions in the first lecture content is received (input) by the student, the student terminal 200 performs an automatic scoring function on the student answer information received for each question in real time. can be done For example, in FIG. 8 , it can be confirmed that the student answer information for the first and second questions among the plurality of questions is scored as correct as a result of automatic scoring, and the student answer information for the third question is scored as incorrect as a result of automatic scoring. there is.

At this time, the student terminal 200 interlocks with the server 100 when a student selects an incorrect problem (for example, a third problem, a third math problem) among a plurality of problems in the content of the first lecture. Any one of the plurality of step-by-step commentary contents related to the third problem) may be output (displayed) on the screen of the student terminal 200 .

Here, the plurality of step-by-step commentary contents may refer to a plurality of commentary contents classified according to an answer inference level that enables a student to infer the correct answer to an incorrect question through the commentary contents provided to the student terminal 200 .

As mentioned above, these plurality of step-by-step commentary contents provide explanation guide content (step 1 commentary content) to provide guidance role content that only presents an approach and direction to solve the problem, and overall content related to the problem. Full-scale commentary content (2nd step commentary content) to provide detailed explanation content related to the problem (3rd step commentary content) Step commentary content (step 4 commentary content) may be included. The plurality of step-by-step commentary content may be content that provides more detailed and easy-to-understand commentary that makes it easier to infer the correct answer to an incorrect problem compared to commentary content with a lower level, as the level of commentary content is higher.

At this time, when the student selects the wrong problem (third problem), in outputting any one of the plurality of step-by-step commentary contents, the student terminal 200, for example, the most step-by-step commentary content among the plurality of step-by-step commentary contents. First-level commentary content corresponding to a lower level (ie, commentary guide content) can be given priority and automatically output as any one commentary content.

However, it is not limited thereto, and as another example, the student terminal 200 displays a plurality of stages on the screen in response to the student's selection input for the wrong problem (third problem) when the student's selection is made for the wrong problem (third problem). After displaying the commentary content selection menu first, the commentary content corresponding to the commentary content selection menu selected by the student among a plurality of step-by-step commentary content selection menus displayed on the screen can be output as any one commentary content.

Here, the plurality of step-by-step commentary content selection menus are selection menus prepared to correspond 1:1 to each of the plurality of step-by-step commentary contents, and may include a guide guide menu, a full-scale commentary menu, a detailed commentary menu, and a basic level commentary menu.

The student terminal 200 outputs first-level commentary content (ie, commentary guide content) on the screen in response to the student's selection of the commentary guide menu, and responds to the student's selection of the full-scale commentary menu. to output the second-level commentary content (i.e., full-scale commentary content) to the screen, and when the student's selection for the detailed commentary menu is made, the third-level commentary content (i.e., detailed commentary content) is output in response to it, and the basic level commentary menu When the student's selection is made, in response to it, the fourth-level commentary content (ie, basic level commentary content) can be output on the screen.

That is, when the student selects the wrong problem (third problem), the student terminal 200 is a commentary content related to the wrong problem, and is directed to a specific step desired (desired) by the student directly selected by the student among a plurality of step-by-step commentary contents. Corresponding commentary content (that is, commentary content corresponding to a commentary content selection menu selected by a student from among a plurality of step-by-step commentary content selection menus) may be provided. According to this, the student can be provided with commentary content corresponding to a specific step desired by the student as commentary content on the wrong problem.

For example, any one commentary content output when a student selects a wrong problem (third problem) (that is, any one commentary output when the student selects any one of a plurality of step-by-step commentary content selection menus) Let's assume that the content or any one of the commentary content automatically output as the commentary content corresponding to the lowest level) is, for example, the first-level commentary content (ie, commentary guide content).

At this time, the student terminal 200, after the output of any one commentary content (step 1 commentary content) on the screen is completed, as shown in FIG. A selection screen including a self-solving item for the following) and an additional request item for asking whether to request additional explanation may be displayed on the screen of the student terminal 200 .

At this time, the self-solving item is for inducing another solution to the wrong problem (eg, the third problem) for the student who has been provided with any one of the commentary content (step 1 commentary content) (i.e., re-solving It may mean a selection item (selection menu) to request. The additional requested item is among the remaining commentary contents except for at least one commentary content (eg, first-level commentary content) provided before the display of the selection screen in relation to the problem (third problem) that the student got wrong among the plurality of step-by-step commentary contents. , may mean a selection item (selection menu) for additionally receiving any one remaining commentary content. That is, the additional requested item is the commentary content previously selected by the student among the plurality of step-by-step commentary contents (for example, the first-level commentary content), as well as other commentary content (ie, any one of the second-level commentary content to the fourth commentary content). ) may mean an optional item for receiving more.

The student terminal 200 displays a wrong problem (third problem) on the screen (ie, displays the problem of the wrong problem again on the screen) when the student selects the self-solving item on the displayed selection screen, The problem solving process (resolving) may be performed again for the incorrect problem that is displayed again, and a real-time scoring function according to problem solving may be provided. That is, the problem-solving process performed again for the incorrect problem re-displayed at this time may mean, for example, a problem-solving process performed by referring to the contents of the first-level commentary content after the student is provided with the first-step commentary content.

On the other hand, when the student terminal 200 selects an additional request item by itself on the displayed selection screen, the remaining commentary contents except for any one of a plurality of step-by-step commentary contents (for example, first-step commentary contents) ( For example, among the commentary contents of steps 2 to 4), any one remaining commentary content may be output.

Here, as one of the remaining commentary contents, for example, one step higher than any one of the commentary contents provided to the student before (immediately) the selection screen is displayed among the remaining commentary contents (eg, commentary contents of steps 2 to 4). Commentary content of the next step may be output. For example, if any one of the commentary contents provided before the display of the selection screen is the first-level commentary content, the second-level commentary content may be provided as one of the remaining commentary contents. As another example, if one of the commentary contents provided before display of the selection screen is the second-level commentary content, the third-level commentary content may be provided as one of the remaining commentary contents.

As another example, any one of the remaining commentary content includes a plurality of step-by-step commentary content selection menus displayed on the screen in response to a student's selection of an additional request item in the selection screen (ie, a commentary guide menu, a full-scale commentary menu, and a detailed commentary menu). Commentary content corresponding to the commentary content selection menu selected by the student among the basic level commentary menus) may be output. For example, if a selection screen is provided after the first-level commentary content is provided to a student, and then the student clicks an additional request item in the selection screen and selects a basic level commentary menu in a plurality of step-by-step commentary content selection menus, the student terminal ( 200) can output (display) the 4th level commentary content corresponding to the basic level commentary menu as one of the remaining commentary contents.

The student terminal 200 may repeatedly display a selection screen (a selection screen including self-solving items and additional request items) on the screen whenever output of any one of the plurality of step-by-step commentary contents is completed. Accordingly, whenever the student is provided with any one of the plurality of step-by-step commentary contents, the student decides whether to solve the problem by himself or receive additional commentary contents and selects the self-solving item or the additional request item. , the function for the selected item can be provided and performed.

That is, in relation to the wrong problem, the student terminal 200 provides 'a process of providing any one of a plurality of step-by-step commentary contents, a process of providing a selection screen thereafter, any one item in the selection screen (self-solving item and A plurality of step-by-step commentary content selection menus are displayed on the screen to re-display the incorrect problem according to the student's selection of any one of the additional request items or to provide commentary content different from any one of the plurality of step-by-step commentary content. The 'process displayed in' can be set as one set (one cycle), and this can be repeated multiple times until the student gives the correct answer to the wrong question.

The student terminal 200 changes the type of commentary content provided according to the number of wrong questions (for example, a plurality of step-by-step commentary Instead of giving priority to the lower level of content and increasing the level as the number of errors increases, explanation content is provided sequentially), multiple step-by-step commentary even in the case of providing only one commentary content when the third problem is incorrect Among the contents, it is possible to provide commentary contents of a specific level desired by the student, selected by the student's will. Accordingly, the student terminal 200 may calculate a quantified correct answer score in consideration of the type of commentary content provided right before the student repeats the wrong problem and gives the correct answer.

The student terminal 200 performs a problem-solving process by selecting a self-solving item for a problem in which a student who has been provided with any one of a plurality of step-by-step commentary contents provides an answer to an incorrect problem (for example, a third problem). If it is detected that the correct answer is correct, a quantified correct answer score for an incorrectly answered problem may be calculated and provided. In this case, the quantified correct answer score may refer to a correct answer score in which a student's learning level for an incorrectly answered question is reflected.

At this time, the student may repeat the problem solving process for the wrong problem at least once before correcting the wrong problem (third problem). In this case, since the number of the plurality of step-by-step commentary contents is 4, the number of re-execution of the problem-solving process for the wrong problem may be up to 4 times.

According to this, illustratively, in relation to the wrong problem (third problem), the student repeats the problem-solving process once after providing the first-level commentary content, and again, after providing the second-step commentary content after making a mistake, the second problem-solving process is repeated. If it is wrong again, after providing the 3rd level commentary content, the 3rd problem solving process is repeated, and if it is wrong again, then after the 4th level commentary content is provided and then the 4th problem solving process is repeated. can give you the right answer. That is, the student can get the correct answer by repeating (redoing) the problem-solving process 4 times for an incorrect problem, for example.

As another example, the student may correct the correct answer by re-performing the problem-solving process once for the wrong problem. At this time, examples of cases in which the correct answer can be obtained by re-performing the problem-solving process once may exist in various ways as follows. For example, 1) In case of correct answer after receiving only the first-level commentary content, 2) In case of correct answer after being provided with the first-level commentary content and second-level commentary content, 3) In case of receiving the first-level commentary content and answering the question 3 If the correct answer is correct after being provided with the commentary content, 4) If the correct answer is correct after being provided with the step 3 commentary content and the step 4 commentary content is provided, 5) Provided with the step 3 commentary content There may be various cases such as a case where the correct answer is given after receiving the 4th step commentary content, 5) a case where the correct answer is correct after being provided with the 4th step commentary content and the 1st step commentary content.

According to this, the student terminal 200 provides the student with commentary content for a problem that the student (learner) fails to solve (for example, by making a mistake on the third problem) to the student, the commentary content for each step. After providing the student, you can ask them to solve the wrong problem again (you can solve the wrong problem again through the provision of self-solving items). At this time, the commentary content provided to the student is the commentary content that is automatically provided sequentially by giving priority to the commentary content of the lower level among the plurality of step-by-step commentary contents, or the commentary content that the student selects first according to the student's choice at that time. It may be commentary content provided in order. In addition, when the commentary content is provided to the student, the correct answer may not be provided (ie, when the commentary content is provided, the correct answer may not be derived and provided).

Thereafter, when the student repeats the wrong problem and gets a correct answer, the student terminal 200 may calculate a quantified correct score for the wrong problem (third problem). The student terminal 200 determines which level of commentary content from among a plurality of step-by-step commentary contents and solves the problem (in particular, which level of commentary content was viewed and the correct answer was met) and quantifies it as a score to quantify the correct answer. score can be calculated.

The quantified correct score is calculated by considering the type of level of explanation content provided to the student (particularly, the level of level of explanation content provided immediately before correct answer), and the student's score for the wrong problem (third problem) with the correct answer. This may mean a correct answer score in which a learning level is reflected.

Exemplarily, for the wrong problem (problem 3), if the student answered the correct answer without being provided with any one of the plurality of step-by-step commentary contents (that is, without receiving any commentary content, re-solving the correct answer) ), the quantified correct score for the incorrectly answered question (third problem) may be 100 points, assuming that the perfect score is 100 points. If the student gives the correct answer after seeing the first-level commentary content (that is, if the level type of the commentary content provided right before the correct answer is the first-level commentary content), the quantified correct answer score for the wrong question (the third question) that the student answered correctly may be 80 points. If the student gives the correct answer after seeing the second-level commentary content (that is, if the level type of the commentary content provided immediately before the correct answer is the second-level commentary content), the quantified correct score for the incorrect question (third question) that the student answered correctly may be 60 points. If the immediately provided commentary content is the third-level commentary content, the quantified correct answer score may be 40 points, and if the immediately provided commentary content is the fourth-level commentary content, the quantified correct answer score may be 20 points. If, despite being provided with all of the plurality of step-by-step commentary contents, the student did not get the correct answer as a result of repeating the wrong question (the third problem), or in a state where he could not get the correct answer to the wrong question, the student provided in one area of the screen If a correct answer is provided by clicking the correct answer exposure button, the quantified correct answer score may be 0 points.

According to this, quantified correct answer points for incorrectly answered questions may be differently determined (set) according to the type of level of commentary content provided right before correct answers, with different numerical values of points assigned. In the above example, the numerical value of the quantified correct answer score for the incorrectly answered question is exemplified as being differentially set to 80 points, 60 points, 40 points, and 20 points, respectively, according to the level type of the commentary content provided immediately before. It is only one example to help understanding of the present invention, but is not limited thereto, and can be set/changed in various ways by an administrator who manages the present system 10.

As another example, the quantified correct answer score for incorrectly answered questions (ie, the numerical value of the quantified correct answer score for incorrectly corrected questions) is the total number of questions in the content of the first lecture including incorrect questions (for example, Since questions 1 to 3 are included, a total of 3), the correct answer standard score given to the incorrect question (the 3rd question) in the content of the 1st lecture, and the type of level of the commentary content provided immediately before can be determined differently. Here, the reference score for correct answers of each question may mean a reference score given when each question is correct. Exemplarily, when there are questions 1 through 3 in the content of the first lecture, the standard score for correct answers for the first question is 30 points, the standard score for correct answers for the second question is 30 points, and the standard score for correct answers for the third question is 30 points. It may be 40 points, and accordingly, if you get all three questions correct, you may get 100 points.

At this time, considering that the standard score for the correct answer of the third problem is 40 points, the student terminal 200 sets the perfect score for the quantified correct answer to the wrong problem (third problem) to be 4 points if there is no commentary content provided immediately before. Assuming 40 points, when the level type of the commentary content provided immediately before is 1 to 4, the quantified correct answer scores can be calculated as 35 points, 30 points, 25 points, and 20 points, respectively.

In addition, when the student terminal 200 detects that the correct answer to the wrong question (third problem) is correct, the total correct score for the lecture content (for example, the first lecture content) including the incorrectly answered question, and the incorrect answer A quantified total correct answer score considering the quantified correct answer score for the problem may be provided. Here, the first lecture content may refer to lecture content corresponding to a specific unit title item (ie, the property item 510 of natural numbers) according to the previous example.

For example, the total correct score may mean 100 points because the student solved the third problem incorrectly and solved again, and therefore all the problems (first to third problems) in the first lecture content were correct. On the other hand, the total correct score for quantification is 95 points if the student answered the correct answer after watching the explanation content of step 1 (since problem 1 is 30 points, problem 2 is 30 points, and problem 3 is 35 points, 95 points) can be If the student gets the correct answer after viewing the commentary content for step 2, the total correct answer score for quantification is 90 points. If you get it right, the total correct score for the quantification may be 80 points.

According to this, the student terminal 200 may calculate and provide quantified overall correct score for each unit in the lecture enrollment screen. At this time, the quantified total correct score of each unit is the total score of the unit (i.e., by re-performing the problem solution according to the provision of commentary content), which is scored in consideration of the quantified correct answer score for the wrong problem in each unit It may mean a total score reflecting the quantified correct answer score given.

The student terminal 200 may calculate and provide quantified correct answer scores for incorrectly answered questions and quantified total correct score of each unit reflecting the quantified correct score, so that the student can calculate and provide a quantified correct score of any unit among a plurality of units in the lecture enrollment screen. It is possible to quantify the correct answer based on the explanation content at which level of the problem. That is, the student terminal 200 can objectively quantify which unit problem has been solved based on which level of explanation content (in other words, which student is You can quantify whether or not you got the right answer by listening to the explanation of the steps and re-solving the wrong problem.

By using the quantified correct answer score and the quantified overall correct score provided by the student terminal 200, the present invention (this system, this server, and learning terminal) determines which unit among a plurality of units in the student's overall learning level and lecture attendance screen It is possible to accurately and objectively judge (identify) whether or not one is weak, and based on the result of this judgment (judgment data), it is possible to extract and provide problems necessary for student (learner) or level improvement. That is, the student terminal 200 can objectively determine the student's level of learning or understanding of the wrong problem or the unit including the wrong problem based on the quantified correct score or the total quantified correct score. At least one additional problem may be provided that matches the student's learning level or allows the student's learning level to be improved.

The student terminal 200 may vary and provide the number of additional questions provided to the student according to the quantified correct score or the total quantified correct score. The number of additional questions may be set to a greater number as the numerical value of the quantified correct answer score or the total quantified correct answer score increases. For example, the number of additional questions provided may be set to 1 if the quantified correct answer score is 100 points, 2 if 80 points, 3 if 60 points, 4 if 60 points, and 5 if 20 points. That is, the lower the quantified correct answer score or the quantified overall correct score, the lower the student's learning level (level of understanding) and basic understanding of the wrong problem, so that more problems can be solved again. A number of additional problems can be provided.

Meanwhile, when the student terminal 200 outputs lecture content (first lecture content) including a plurality of problems (eg, first to third math problems) on the screen, a solution is provided for each problem in the first lecture content. A process input button can be displayed together. At this time, when the student clicks on the first solution process input button of the first problem (for example, the first math problem) among the plurality of problems, the first solution process input screen is displayed on the screen of the student terminal 200. can do. The solution process input screen may refer to a screen on which a process of solving a corresponding problem, such as a formula solving process or a formula expansion process of the corresponding problem, can be recorded. That is, the student terminal 200 may display a solution process input screen for inputting a problem solution process for each problem with respect to each of a plurality of problems in the content of one lecture.

Here, the first solution process input screen includes a first area where the first problem is exposed, a second area where the student can input information on the solution process of the first problem, and a first area where the student can input the answer to the first problem. It can include 3 areas, a completion button and a window close button. In this case, the student solution answer input to the third area may mean answer information input by the student to the first problem, that is, student answer information. That is, the first region may be referred to as a first problem exposure region, a second region as a solution process information input region, and a third region as an answer input region.

Here, in the first solution process input screen, the first area may be provided, for example, on one area at the top of the screen (display liquid crystal screen) of the student terminal 200 . The second area may be provided in the central area of the screen of the student terminal 200 . The third area may be provided in a different area from the first area and the second area, or may be provided in a part of the first problem displayed in the first area (for example, an area corresponding to an option). A completion button may be provided on a lower area of the screen of the student terminal 200, and a window close button may be provided on an upper right area of the screen. However, this location setting is only one example to help understanding of the present invention, and is not limited thereto, and may be set or changed in various ways by the administrator of the present system 10 .

The second area of the first solving process input screen, that is, the solving process information input area, may be movable in up, down, left, right and diagonal directions by, for example, a student's drag input. That is, when the student wants to solve the first problem, he or she can enter the solution process of the first problem in the second area and perform the problem solving. At this time, the student terminal 200 has a screen size such as a smartphone, for example In the case of a small mobile terminal, since the screen size is limited, the space may be too small to input the entire solution process of the first problem. Therefore, when the student inputs the solution process of the first problem, if there is no or insufficient space to input data on the current screen, the second area is dragged and moved in the desired direction among the left / right / up / down / diagonal directions. The screen can be moved so that the screen of an empty space where no data is input is displayed. The screen corresponding to the second area may be screen scrolled in the direction the student dragged by the student's dragging input to the second area. Through this process, the student can input the entire solution process of the first problem into the second area.

Through the provision of the first solution process input screen, the student may perform the solution of the first problem through the student terminal 200 possessed by the student. In particular, while viewing the first problem exposed in the first area, the student can solve the problem while directly inputting (writing down) the solution process of the first problem in the second area on the screen of the student terminal 200. there is. At this time, as the screen of the second area is provided to be movable, the student directly inputs the entire solution process on the student terminal 200 without being restricted by the screen size, even if the screen of the student terminal 200 is small. can perform problem solving.

In addition, the student terminal 200 clicks the Done button after the student enters the solution process information of the first problem in the second area and the answer (student solution answer) in the third area on the first solution process input screen. If the window close button is clicked in the first solution input screen or the first solution process input screen, the student solves the problem for the first problem based on the solution process information of the first problem input in the second area in response (ie, the first problem Problem solving process information) may be scored in real time, and content of the first lecture reflecting the real-time scoring result of the first problem may be displayed on the screen.

However, it is not limited to this, and as another example, the student terminal 200 responds to the student's click input on the completion button when the completion button is clicked on the first problem-related first solution process input screen. The input screen for the second solution process related to the second problem can be automatically displayed on the screen so that the second problem (second math problem), which is a follow-up to the first problem (first math problem) in the content of the first lecture, can be solved. there is.

In this case, the student terminal 200 displays the solution process input screen (ie, the first solution process input screen to the third solution process input screen) for each of the plurality of problems in the first lecture content to the student for the completion button in each screen. It can be displayed on the screen sequentially in response to the click input of a plurality of problems, and when a student clicks on the completion button in the solution process input screen for the last problem (for example, the third problem) of the plurality of problems, the plurality of problems Real-time scoring may be performed on each of the problems, and content of the first lecture reflecting the real-time scoring results of the plurality of problems may be displayed on the screen. In this way, by automatically displaying the next problem input screen when clicking the completion button in the first solution process input screen, the student solves the problem for each of the plurality of problems in the first lecture content. , While viewing each problem more smoothly on a larger screen through the student terminal 200 (that is, while viewing each problem expressed in large letters compared to the letters written in the content of the first lecture in which a plurality of problems are expressed together, only one problem is expressed ) can be provided so that problem solving can be performed while directly entering the solution process.

In the present invention, the description of the first problem (or the first solution process input screen) is the same as the description of each of the plurality of problems (or the solution process input screen for each of the plurality of problems), even if the content is omitted below. can be applied

In addition, the student terminal 200 determines that when the content of the first lecture reflecting the real-time scoring result of the first problem is displayed on the screen, the real-time scoring result of the first problem (result of performing the real-time scoring function) is an incorrect answer, and the first problem When a student clicks on the 1st wrong answer solution button created to respond to the 1st question (wrong answer question, wrong question) determined to be an incorrect answer in the content of the 1st lecture reflecting the real-time scoring results, the first incorrect answer solution button In response to a click input for , information on a first incorrect answer solution analysis of a first problem determined to be an incorrect answer may be displayed on the screen. In this case, the first problem determined as an incorrect answer means an incorrect problem, and may be referred to as the first incorrect problem for convenience of description below.

At this time, the student terminal 200 does not unconditionally display the first incorrect answer solution analysis information on the screen when the student clicks on the first incorrect answer solution button. Only when all contents are output on the screen of the student terminal 200, when a click is input on the first wrong answer solution button, the first incorrect answer solution analysis information can be displayed on the screen. At this time, the fact that all of the plurality of step-by-step commentary contents related to the first problem are output on the screen of the student terminal 200 means that the student has viewed all of the plurality of step-by-step commentary contents and, accordingly, solves the wrong first problem at least once. It may mean that it was repeated (the problem-solving process for the wrong first problem was re-performed at least once).

The first incorrect answer solution analysis information is analyzed by comparing the solution process information (incorrect answer solution process information) of the first problem input by the student in the second area on the first solution process input screen with the correct answer solution process information of the first problem. may be information. Hereinafter, for convenience of description, the solution process information of the first problem will be referred to as first solution process information, and the correct answer solution process information of the first problem will be referred to as first correct answer solution process information. Here, the first correct answer solution process information may mean the entire solution process (eg, formula solving process, formula development process) for deriving the correct answer to the first problem.

At this time, the student terminal 200 performs letter recognition processing on the first solution process information input to the second area in order to display the first incorrect answer solution analysis information on the screen, and the data input value corresponding to the first solution process information. It is possible to identify an incorrect answer trigger point in the first solution process information by extracting and analyzing the extracted data input value. Thereafter, the student terminal 200 provides first incorrect answer solution analysis information including first solution process information indicating a point causing an incorrect answer and correct answer process information (first correct answer solution process information) by correcting the data of the point causing an incorrect answer. can be displayed on the screen. At this time, the correct answer solution process information included in the first incorrect answer solution analysis information is based on the position of the incorrect answer inducing point, and the subsequent correct answer solving process information (ie, correction from the incorrect answer inducing point in the first solving process information input by the student) It may mean the corrected first solution process information corrected to match the correct answer solution process information), or the correct answer solution process information of the first problem (ie, the basic overall correct answer solution process information of the first problem) could mean

In the above description, the first solution process information (solution information of the first problem) input to the second area includes image information of the first solution process information and input characteristic information of data corresponding to the first solution process information. may be included. That is, the first solution process information includes image information including information on the problem solving process entered by the student when solving the problem of the first problem, and data input of data input when solving the problem of the first problem. Input feature information such as order (stroke order) and data input acceleration may be included. The first solution process information input to the second area is, for example, information input by a student performing a touch or drag with a finger using a hand, or information input using a stylus pen connected to the student terminal 200. can be

The student terminal 200 may extract a data input value corresponding to the first solution process information by performing a character recognition process on the first solution process information. In this case, the text recognition process may be, for example, OCR (optical character reader) process. Thereafter, the student terminal 200 may identify an incorrect answer trigger point in the first solution process information through analysis of the extracted data input value.

In this case, an artificial intelligence model may be used when analyzing the extracted data input value. The artificial intelligence model may mean a deep learning model, an artificial intelligence (AI) algorithm model, a machine learning (machine learning) model, a neural network model (artificial neural network model), a neuro fuzzy model, and the like. In addition, the artificial intelligence model is conventionally known or developed in the future, such as a convolution neural network (CNN), a recurrent neural network (RNN), and a deep neural network. Various neural network models may be applied.

The student terminal 200 converts the extracted data input value and the first solution process information (ie, the image information of the solution process information and the first solution process information including the input feature information of the data corresponding to the first solution process information) It is applied as an input value of the artificial intelligence model, and in relation to the analysis of the extracted data input value, a semantic analysis of the solution process of the first solution process information entered by the student in the second area is performed through the artificial intelligence model. can That is, the student terminal 200 may perform semantic analysis of data input values for the solving process of the first solving process information input to the first area by using the artificial intelligence model. Such semantic analysis may mean analysis of the meaning, significance, relationship, etc. of a data input value (for example, a solution process of a formula development process) for the solution process of the first problem performed by the student.

In relation to the first problem, the artificial intelligence model sets the first solution process information, the extracted data input value, and the correct answer process information of the first problem (ie, the first answer solution process information) as an input value, , By performing semantic analysis on the solution process of the first solution process information based on the input value, it is possible to output the first solution process information (for example, an image) in which the wrong answer trigger point is displayed as an output value corresponding to the input value.

In addition, such an artificial intelligence model is, for example, a plurality of solution process information about the first problem (or each of a plurality of problems) input by a plurality of users (eg, students, teachers, etc.), data extracted from each solution process information It may be a pre-learned model that takes the input value and the first problem as learning input data as an input value, and sets information on a solution process in which an error triggering point matching each learning input data is displayed as an output value.

As described above, when the student gets the first problem wrong, the student terminal 200 determines at what point in the solution process in the first solution process information input in relation to the first problem the student started solving the wrong answer. By performing letter recognition processing on the point (i.e., the point of causing the wrong answer) and using the artificial intelligence model, it is possible to automatically determine (identify) based on the first solution process information on its own, and based on the result, the first incorrect answer solution Analytical information can be provided. According to this, the student terminal 200 provides analysis information on solving the first incorrect answer so that the student can determine which part in the process of solving the first problem he/she made a mistake in solving and how to actually solve the solution at the position where he or she missolved the wrong answer. Incorrect answer solution analysis information may be provided in a form in which it is easier and more intuitive to understand whether the first problem could be correctly answered only if the first problem had been answered. That is, through the first incorrect answer solution analysis information, the student can effectively receive and recognize the point of the part that the student incorrectly solved or the normal correct answer solution approach method for the corresponding part.

In addition, for example, each problem in the content of the first lecture (for example, each of the first to third math problems) may be pre-classified (set) into mental arithmetic problems and non-mental arithmetic problems according to problem difficulty. At this time, the classification of mental arithmetic problems and non-mental arithmetic problems for each problem may be set by the manager who manages the system 10 as an example, but is not limited thereto, and as another example, correct answers for each problem may be set. It may be set based on analysis information of a plurality of users (students, teachers, etc.) of a plurality of solutions related to correct answers (ie, solution process information for correct answers input through a solution process input screen).

In the latter case, for example, as a result of averaging the time required to calculate the correct answer for each of the plurality of solution process information related to the correct answer to the first problem, the average correct answer calculation time required for the first problem is less than a preset time (eg, 3 minutes) , the first problem can be classified as a mental arithmetic problem. On the other hand, for example, when the average correct answer calculation time for the first problem is longer than a preset time (eg, 3 minutes), the first problem may be classified as a mental arithmetic problem.

At this time, in relation to the first problem, the time required to calculate the correct answer of the first student's correct answer-related first solution process information is, for example, the time when the first student starts inputting the problem solution into the second area of the first solution process input screen (ie, .

In addition, a minimum required time for calculating an answer may be previously set for each problem in the contents of the first lecture. In this case, the minimum required time for calculating the correct answer may mean the minimum required time required to solve the corresponding problem. The minimum required time for calculating the correct answer is, for example, a plurality of solution process information related to the correct answer of a plurality of users (students, teachers, etc.) who have correctly answered each question (ie, the solution process input information for the correct answer entered through the solution process input screen). s) may be set based on analysis information. For example, the minimum required time for calculating the correct answer for the first problem may be set to the time required for calculating the correct answer having the minimum value among the required times for calculating the correct answer for each of the plurality of solution process information related to the correct answer for the first problem.

In other words, the minimum required time to calculate the correct answer for each problem is based on the solution information of a plurality of users who solved each problem and answered the correct answer (ie, the time required to calculate the correct answer, which is the time required for each user to calculate the correct answer). It may be set to a time required to calculate an answer having a minimum value. Accordingly, the minimum time required to calculate the correct answer for each question may be set to different values. For example, the minimum required time for calculating the correct answer for the first problem may be set to 2 minutes, the minimum required time for calculating the correct answer for the second problem may be set to 5 minutes, and the minimum required time for calculating the correct answer for the third problem may be set to 4 minutes.

At this time, the student terminal 200, for example, has already classified (set) the second problem (second math problem) in the content of the first lecture as an impossible problem for mental arithmetic (this is at least 3 minutes when solving the second problem (preset It means that it takes more than 3 minutes), and the second problem is solved without inputting the solution process information (second solution process information) through the second area in the second solution input screen in relation to the second problem. If the correct answer is received as the student answer information (ie, the answer information for question 2 entered by the student is the correct answer), the received student answer information indicates that the student did not solve the second question properly and did not know the correct answer. It is suspected that it is correct, and the real-time scoring result for the second problem can be first judged as a provisional incorrect answer.

Thereafter, if the student terminal 200 is first judged as a provisional incorrect answer, the second solution process input screen is exposed on the screen to receive the second solution process information through the second area from the student, and the received second solution process information The calculated correct answer calculation time is calculated, and the calculated correct answer calculation time is less than the minimum correct answer calculation time (for example, 5 minutes) set in the second problem (for example, the calculated correct answer calculation time is 4 minutes 10 As a result of comparing the second solution process information and the answer-solving process information of the second problem, if it is analyzed that the second solution process information does not include all of the correct answer-solving process information of the second problem, the student selects the second problem. Taking the problem and giving up in the middle without completing the solution of the problem to the end and correcting the answer (i.e., simply taking the answer without knowing the correct answer to the second question) or the correct answer of the student's answer information entered by the student is the correct solution process It is judged that the correct answer was guessed by coincidence even though the solution process, not the correct answer derived by As a result of the difference judgment (final judgment), it is possible to finally determine that the student's answer information is an incorrect answer even though it has an actual correct answer value. That is, in this case, the student terminal 200 may finally determine the real-time scoring result for the second problem as an incorrect answer.

On the other hand, in the student terminal 200, while the calculated correct answer calculation time is greater than the preset correct answer calculation time (for example, 5 minutes) or more (for example, the calculated correct answer calculation time is 8 minutes) ) As a result of comparing the second solution process information with the correct answer process information of the second problem, if it is analyzed that the second solution process information includes all the correct answer process information of the second problem, the student answer information entered by the student It is judged that the correct answer is the correct answer derived by the correct solution process (ie, the correct answer was answered while accurately knowing the correct solution process of the second problem), and the correct answer that was first judged as a provisional incorrect answer (ie, the second problem It is possible to make a second (final judgment) determination that the correct answer information of the student's answer to the problem is actually the correct answer, and as a result, it may be finally determined that the student's answer information is the actual correct answer. In this case, the student terminal 200 may finally determine the real-time scoring result for the second problem as the correct answer.

That is, the student terminal 200 does not determine and provide real-time scoring results as correct even if the student answer information for a specific problem (for example, the second problem) has a correct value, but (1) the second problem is mentally calculated. Information about which type of problem belongs to the impossible problem and the mental arithmetic problem, (2) the time required to calculate the correct answer of the second solution process information (ie, the time required for the student to solve the second problem), ( 3) Comprehensively considering whether the minimum required time (eg 5 minutes) to calculate the correct answer set for the second problem and (4) whether the second solution process information includes all the correct answer process information for the second problem By performing the first judgment and the second judgment, it is possible to determine whether a real-time scoring result for the second question is a correct answer or an incorrect answer and provide it. According to this, the student terminal 200 allows the real-time scoring result to be derived as the correct answer only for the correct answer in a state in which the student correctly and accurately recognizes the problem-solving process of the specific problem. A correct answer corrected in a state in which the solution process is not precisely known may result in a real-time scoring result as an incorrect answer, so that a real-time scoring result considering the student's level of understanding of a specific problem may be provided.

In addition, the student terminal 200 may display (provide) a company information providing menu on one area of its screen, for example. Here, the company may mean a company (offline store) such as a school that provides education to students (users), such as math and language academies.

For example, when a student clicks a company information providing menu displayed on the screen of the student terminal 200, in response to this, the student terminal 200 provides information on a plurality of academy companies previously registered in the company DB (not shown). can The company DB (not shown) may store the company name, business hours, address, and the like of the academy company as information on the academy company. The company DB may be provided in the present server 100 or in the student terminal 200 . At this time, the student terminal 200 may display a map in which locations of a plurality of private academy companies are indicated by mark icons when providing information on a plurality of private academy companies on the screen.

At this time, when displaying the map, the student terminal 200 displays a mark corresponding to available academy companies available at the time of selection from a plurality of academy companies based on the selection point when the student selects (clicks) the company information providing menu. The icon may be displayed in a form that is easier to recognize or identify than a mark icon corresponding to an unavailable academy company that is unavailable at the time of selection.

At this time, displaying the mark icon corresponding to the available academy company in a form that is easier to recognize or identify than the non-available academy company means that the visually emphasized form (for example, the border line of the mark icon corresponding to the available academy company) color or thickness may be different), a form with an expanded size, a form accompanied by an auditory effect, and a dynamic animation form.

For example, the student selects (clicks) the company information provision menu to receive information on academy companies located around him based on his current location (current GPS location information of the student terminal 200) , Suppose that there are three academy companies located around the student's current location. In this case, the student terminal 200 may display on the screen a map in which the locations of three academy companies (ie, the first academy company to the third academy company) are indicated by mark icons as a plurality of academy companies.

Here, each academy company has a difference in business hours (eg, 24 hours for the first academy company, 6:00 to 23:00 for the second academy company, 5:00 to 23:00 for the third academy company, etc.) There may be. In addition, each academy company may have different closing times (business hours) due to personal circumstances (personal circumstances of the president who runs each academy company) and differences in vacation schedules.

For example, let's assume that at the time the student selects the company information provision menu (corresponding time zone), the first and second academy companies are operating normally, and the third academy company is not currently operating due to personal circumstances. . In this case, the student terminal 200 may recognize the first and second academy companies as usable academy companies, and recognize the third academy company as unavailable academy companies. Thereafter, the student terminal 200 compares the mark icon corresponding to the available academy company (ie, the first/second academy company) with the mark icon corresponding to the unavailable academy company (ie, the third academy company) for further recognition. Alternatively, it may be displayed on a map in an easy-to-identify form.

Exemplarily, the student terminal 200 displays a mark icon corresponding to an available academy company in a larger size, a darker color, or more recognition ( It is possible to display differently by adding a flickering effect so that the engraving) is well displayed.

In this way, the student terminal 200 distinguishes and displays available academy companies and academy companies at the time of selection based on the time when the student selects the company information providing menu, so that the student is currently operating and is currently operating. Since it is possible to more intuitively grasp information on academy companies that are available (consultation, lecture reception, and enrollment), it can help students find and use available academy companies quickly without wandering. .

That is, the student can easily find, for example, an academy company located close to his or her current location or a specific location directly designated by the user through a map showing the locations of a plurality of academy companies. In particular, students can more easily and quickly find and use available academy companies that are available right now, among a plurality of academy companies displayed on the map. For example, a student (user) visits a specific academy company and is on vacation It can solve the inconvenience of having to find another academy company again when it is impossible to use it because the door is closed for reasons. In addition, students (users) can grasp the map provided through the student terminal 200 more intuitively and quickly, without the hassle of calling the corresponding academy company individually to inquire whether it is currently available.
