In the present embodiment, when the input unit 15 detects an input requesting the display of the student's grade screen or the like, the control unit 16 transmits a predetermined request signal to the server device 20 via the communication unit 13. Then, when the communication unit 13 receives the display data D1 as a response to the above-mentioned request signal from the server device 20, the control unit 16 displays a screen based on the display data D1 on the display unit 17.

FIG. 2B is a block diagram showing the configuration of the server device 20. The server device 20 includes a communication unit 21, a storage unit 22, and a control unit 23. It should be noted that these components, the test information DB 24, and the test result DB 27 are connected to each other via the bus 29.

The communication unit 21 is a communication unit for communicating with the terminal device 10 through the network 9.

The storage unit 22 is composed of memories such as RAM and ROM. The storage unit 22 stores programs for various processes executed by the control unit 23. The storage unit 22 may include at least one of the test information DB 24 and the test result DB 27.

The control unit 23 is composed of a processor (computer) such as a CPU and a GPU, and controls each component of the server device 20. When the communication unit 21 receives a display request related to the result transition screen or the like from the terminal device 10, the control unit 23 generates the display data D1 to be supplied to the terminal device 10 by referring to the test information DB 24 and the test result DB 27. Then, the generated display data D1 is transmitted to the terminal device 10 by the communication unit 21. The control unit 23 is an example of a computer that executes an acquisition means, an extraction means, a grade display means, and a program.

The test information DB 24 stores test information which is information about a test to be performed by a student. In the present embodiment, the test information includes, in addition to test question information, point allocation information, and correct answer information, information related to the classification of the unit to which each question belongs (also referred to as "question attribute information"). The data structure of the question attribute information will be described later with reference to FIG.

The test result DB 27 stores the test result information, which is information on the execution result of the test conducted in the past, in association with the identification information of the student who conducted the test and the like. The test result information includes, for example, information on the type and timing of the test performed, identification information of each student who took the test, and answer information indicating the answer described by each student (stroke information for reproducing the handwriting of the answer). Includes), correct / incorrect information for each student's question, score rate for each student's unit and other categories (including viewpoints and areas described later) (may be the correct answer rate, the same shall apply hereinafter). In addition, instead of storing the above-mentioned score rate information in the test result DB 27 in advance, the server device 20 stores the correct / incorrect information for each question of the target student included in the test result DB 27 and the test information of the corresponding test information DB 24. The above-mentioned score rate may be calculated based on the unit and classification for each question shown.

FIG. 3 is an example of the data structure of the question attribute information included in the test information DB 24. The question attribute information is each of the "unit", "area", and "viewpoint" to which each question belongs for each combination of "large question" and "small question", which are items that specify the question included in the target test. Information to which items are associated. Here, the "unit" indicates the unit to which the target question belongs, and the "area" indicates the classification to which the target question belongs and is a classification of a higher concept than the unit. "Viewpoint" indicates the viewpoint (skill, knowledge, understanding, etc.) necessary for solving the target question.

The test information DB 24 and the test result DB 27 may be an external storage device such as a hard disk connected to or built in the server device 20, a storage medium such as a flash memory, and data communication with the server device 20. It may be a server device or the like that performs the above. In this case, the device for storing the test information DB 24 and the test result DB 27 is composed of a plurality of devices, and each of the above-mentioned storage units may be distributed and held.

[Grade display processing]
Next, the display regarding the student's grades displayed on the terminal device 10 by the server device 20 will be described. Generally, the server device 20 extracts a student whose score rate difference with respect to the entire student is larger than the threshold value as compared with the previous test as a warning target student (also referred to as a “warning target student”). And highlight the grades of the student subject to the warning. As a result, the server device 20 makes the teacher who is the user of the terminal device 10 preferably grasp the students who need guidance, advice, and the like.

(1) Grade list screen FIG. 4 is a display example of the grade list screen. As shown in FIG. 4, the terminal device 10 has a grade list display column 30, a first designated column 31, a second designated column 32, and a third designated column based on the display data D1 transmitted from the server device 20. 33 is displayed on the grade list screen. In this case, for example, when the server device 20 receives the display request of the grade list screen from the terminal device 10, the server device 20 extracts the test result information of the students of the class specified in the above display request from the test result DB 27, and obtains the test result DB 27. Display data D1 is generated based on the test result information.

The grade list display column 30 is a column for displaying a list of student grades, and has items of "number", "name", "current score rate", "overall score rate difference", and "alert". The "number" and "name" indicate the class number (attendance number) and name of the target student. The "current score rate" indicates the score rate obtained by the target student in the target subject in the latest (latest) test. The target subject is the subject designated in the third designated column 33, which will be described later. The "overall score rate difference" indicates the score rate obtained by subtracting the corresponding current score rate by the overall score rate in the same test. Here, the overall score rate refers to the average score rate of those who have taken the test, and may be the average score rate in the class or the average score rate of the entire grade. In the example of FIG. 4, since the overall score rate is 66%, the server device 20 displays the value obtained by subtracting 66 from the value of the “current score rate” in the “overall score rate difference”.

The "alert" is a column in which a black circle is displayed when the target student is a warning target student. Here, the server device 20 considers a student whose "overall score rate difference" shown on the grade list screen is lower than a predetermined threshold value with respect to the overall score rate difference of the previous test as a warning target student. In other words, the server device 20 has a variation value (also referred to as "performance variation value dR") of the overall score rate difference of the target test (latest test) with respect to the overall score rate difference of the test of the same subject conducted immediately before. A student whose.) Is less than or equal to the predetermined standard fluctuation value is regarded as a warning target student. In this case, the grade variation value dR is a value obtained by subtracting the overall score rate difference of the previous test from the overall score rate difference of the latest test. Further, the above-mentioned reference fluctuation value is a threshold value for determining whether or not the grade has substantially decreased, and is set to, for example, a predetermined negative value. As will be described later, when it is selected in the second designation column 32 that the server device 20 alerts a person whose grade is higher than that of the previous test, the result fluctuation value dR is a positive value. Students who exceed the standard fluctuation value of are considered as warning target students.

Then, the server device 20 highlights the record of the warning target student by displaying a black circle in the "alert" column of the warning target student. In the example of FIG. 6, the server device 20 identifies each student of the number 2 “BBBBBB”, the number 4 “DDDDDD”, and the number 7 “GGGGGG” as the student to be warned, and records the corresponding records. A black circle is displayed in the "Alert" field.

The first designated column 31 is a column for selecting whether to display all the students of the target class (here, the third grade C group) or to display only the warning target students in the target class. Here, since "display all" is selected in the first designated field 31, the server device 20 displays a list of grades of all the target classes in the grade list display field 30.

The second designation column 32 is a column for designating the extraction criteria of the students to be warned, and here, the person whose grade is lower than the previous test is alerted, or the person whose grade is higher than the previous test is alerted. It is possible to select whether to do it. Here, the server device 20 selects a student whose grade variation value dR is equal to or less than the reference variation value, which is a negative value, because "Alert a person whose grade has declined" is selected in the second designated column 32. Extract as a warning target student.

The third designated column 33 is a column for designating the subject of grades to be referred to when determining the student to be warned. Here, since "mathematics" is selected in the third designated column 33, the server device 20 displays the current score rate and the overall score rate difference regarding the mathematics grade in the grade list display column 30. Determine the students to be warned based on their math grades. In addition, in the third designation column 33, in addition to each subject such as mathematics, national language, and English, it is also possible to specify all subjects for which the test has been conducted. When all subjects are designated in the third designation column 33, the server device 20 warns with the values to be displayed in each item of "this time score rate" and "overall score rate difference" based on the average value of the grades of all subjects. Determine with the target students. In FIG. 4, the first designated field 31, the second designated field 32, and the third designated field 33 are, as an example, input fields in the form of a pull-down menu.

As described above, in the grade list screen shown in FIG. 4, the server device 20 has the difference in the overall score rate of the test conducted this time for the designated subject (here, mathematics), and the overall score rate of the test conducted last time. Highlight student grades below the threshold below the difference. As a result, the student who is likely to need guidance can be suitably recognized by the teacher who is the user of the terminal device 10.

When the server device 20 detects that an arbitrary student record in the grade list display field 30 has been selected, the server device 20 individually displays the student grades corresponding to the selected record (“grade individual screen”). Also referred to as) display data D1 is generated. Then, the terminal device 10 displays the grade individual screen by receiving the above-mentioned display data D1 from the server device 20. A display example of the individual grade screen will be described later.

FIG. 5 is a display example of the result list screen when "display only alert target" is selected in the first designated field 31. On the grade list screen shown in FIG. 5, the server device 20 detects that "display only alert target" is selected in the first designated field 31, and for all the students displayed in the grade list display field 30 of FIG. Of the records, only the records of the warning target students are extracted and displayed in the grade list display column 30.

As described above, in the grade list screen shown in FIG. 5, the server device 20 grades only the records of the students whose total score rate difference of the test conducted this time is lower than the total score rate difference of the test conducted last time by a threshold value or more. It is displayed in the list display field 30. As a result, the student who is likely to need guidance can be clearly recognized by the teacher who is the user of the terminal device 10.

FIG. 6 is a display example of the grade list screen when "Alert a person who has improved grades" is selected in the second designated field 32.

On the grade list screen shown in FIG. 6, the server device 20 detects that "alert the person who has improved the grade" is selected in the second designated column 32, and selects the student whose grade has improved with respect to the previous test. Identify as a warning target student. Specifically, in this case, the server device 20 identifies a student whose grade variation value dR is higher than the reference variation value set as a positive value as a warning target student. In this case, the reference fluctuation value is a threshold value for determining whether or not the grade has substantially improved, and is set to, for example, a predetermined positive value.

In the example of FIG. 6, the server device 20 determines that the difference in the above-mentioned score rates of each student of the number 1 “AAAAAA” and the number 5 “EEEEEE” is higher than the threshold value with respect to the previous test. Then, the server device 20 regards these students as the students to be warned, and displays a black circle in the "alert" field of these students.

As described above, in the grade list screen shown in FIG. 6, the server device 20 sets a student whose overall score rate difference of the test conducted this time is higher than the overall score rate difference of the test conducted last time by a threshold value or more as a warning target student. Highlight. As a result, for example, the teacher can motivate the warning target student by informing the warning target student that the grade is better than the previous test at the timing of returning the test or the like.

(2) Grade Individual Screen and Question-Specific Correct / Incorrect List Screen FIG. 7 shows an example of a grade individual screen displayed by the terminal device 10 based on the display data D1 generated by the server device 20. The server device 20 detects that the record corresponding to the student "BBBBBB" of the number 2 is selected in the grade list display field 30 on the grade list screen shown in FIG. 4, and refers to the test result information and the like for the student. As a result, the display data D1 for displaying the individual grade screen shown in FIG. 7 is generated.

In the example of FIG. 7, the terminal device 10 displays the graph G1 showing the transition of the grades of the target student “BBBBBB” and the fourth designated column 38 on the grade individual screen based on the display data D1 transmitted from the server device 20. It is displayed above.

Here, the graph G1 is a bar graph showing the results (here, the score rate) of the mid-term test and the final test of the target student "BBBBBB" in the current grade in chronological order together with the overall average. In the example of FIG. 7, the server device 20 generates the display data D1 of the individual grade screen at the end of the final test of the second semester, and the test result DB27 stores the middle of the first semester and the end of the first semester. The graph G1 showing the results of each test in the middle of the second semester and the end of the second semester is displayed.

Further, the server device 20 identifies a test in the graph G1 in which the overall score rate difference is lower than the total score rate difference of the previous test by a threshold value or more, and highlights a bar graph showing the results of the test. .. The above-mentioned threshold value may be the same value as the absolute value of the reference fluctuation value used for determining the warning target student, or may be a different value. In the example of FIG. 7, the server device 20 determines that the difference in the overall score rate of the final test of the second semester is lower than the difference in the overall score rate of the intermediate test of the second semester, which is the test immediately before that, by a threshold value or more. .. Then, in this case, the server device 20 highlights the bar graph showing the results of the final test of the second semester by surrounding it with the edging effect and the broken line frame 40.

As a result, the server device 20 can suitably highlight the test whose performance is lower than that of the previous test.

Further, the bar graph corresponding to each test can be selected, and when the server device 20 detects that the bar graph corresponding to an arbitrary test is selected, each question of the test corresponding to the selected bar graph is selected. Display data D1 for displaying a correct / incorrect list is generated. In this case, the terminal device 10 receives the above-mentioned display data D1 from the server device 20 to show a correct / incorrect list for each test question corresponding to the selected bar graph (also referred to as a “question-specific correct / incorrect list screen”). .) Is displayed.

FIG. 8 is an example of a correct / incorrect list screen for each question. In this case, the server device 20 detects that the bar graph of the second semester final test is selected, and generates the display data D1 of the correct / incorrect list screen for each question regarding the correctness of the mathematics student "BBBBBB" of the second semester final test. Then, the terminal device 10 displays the correct / incorrect list screen for each question shown in FIG. 8 based on the display data D1 received from the server device 20.

The server device 20 is a list having each item of "large question", "small question", "correct / wrong", "overall correct answer rate", "unit", "area", and "point of view" on the correct / incorrect list screen for each question. The table is displayed. Here, the "large question" and the "small question" indicate the identification numbers of the large question and the small question to which the question provided in the target test belongs, respectively. "Correct / wrong" indicates the correctness of the target student's answer to the target question by 〇 (correct answer) or × (incorrect answer). The "overall correct answer rate" indicates the correct answer rate of all students' answers to the target question. “Unit”, “area”, and “viewpoint” indicate the unit, area, and viewpoint to which the target question belongs, respectively.

By displaying the correct / incorrect list screen for each question on the terminal device 10 as shown in FIG. 8, the server device 20 allows the teacher to preferably browse the details of the test selected by the teacher. For example, the teacher who browsed the correct / incorrect list screen for each question shown in FIG. 8 made many mistakes in the test for the student "BBBBBB", which had a relatively high overall correct answer rate, and the unit "Movement of figures". It is possible to understand that "" is not good. Then, the teacher can utilize the information grasped on the correct / incorrect list screen for each question in the guidance to the target student. For example, in this case, the teacher can instruct the student "BBBBBB" to do a review material for the unit "movement of figures", or teach a problem to be done centering on a basic problem. The information displayed on the correct / incorrect list screen for each question is an example of "correct / incorrect information".

The grade individual screen of FIG. 7 will be described again. The fourth designated column 38 is a column for selecting whether or not to include the end-of-chapter test conducted in the class of the target subject (here, mathematics) in the display of the bar graph G1. The fourth designated field 38 shown in FIG. 7 is an input field in the form of a pull-down menu as an example, and either "do not include the end-of-chapter test" or "include the end-of-chapter test" can be selected. In the example of FIG. 7, the server device 20 does not include the results of the end-of-chapter test (that is, only the mid-term test and the final test) because "do not include the end-of-chapter test" is selected in the fourth designated column 38. ) The bar graph G1 is displayed.

FIG. 9 is an example of a grade individual screen when "include test at the end of chapter" is selected in the fourth designated column 38 of FIG. 7. In the example of FIG. 9, the server device 20 detects that "include end-of-chapter test" is selected in the fourth designated column 38, and corresponds to each of the end-of-chapter test, the intermediate test, and the final test as graph G1. A bar graph showing grades in chronological order is displayed. Further, the server device 20 identifies a test in which the overall score rate difference is lower than the total score rate difference of the previous test by a threshold value or more, and highlights a bar graph showing the results of the test. In the example of FIG. 9, the server device 20 determines that the overall score rate difference of the end-of-chapter test regarding the space figure is lower than the overall score rate difference of the second semester mid-term test, which is the test immediately before, by a predetermined threshold value or more. Therefore, in this case, the server device 20 highlights the bar graph showing the results of the end-of-chapter test on the space figure by the edging effect and the broken line frame 41. Similarly, the server device 20 determines that the overall score rate difference in the final test of the second semester is lower than the overall score rate difference in the end-of-chapter test for the plane figure, which is the test immediately before, by a predetermined threshold value or more. Therefore, in this case, the server device 20 highlights the bar graph showing the results of the final test of the second semester by the edging effect and the broken line frame 40, as in FIG.

In the above highlighting, the server device 20 does not have to consider the intermediate test, the final test, and the end-of-chapter test as separate tests, and do not have to compare them. For example, in this case, when determining whether to highlight the mid-term test or the final test, the server device 20 does not compare the results with the end-of-chapter test, but the mid-term test or the final test conducted immediately before that. You may compare the results with the test. Similarly, when determining whether to highlight the end-of-chapter test, the server device 20 does not compare the results with the mid-term test or the final test, but the results with the end-of-chapter test conducted immediately before that. A comparison may be made.

Further, instead of or in addition to highlighting the bar graph corresponding to the test in which the overall score rate difference is lower than the threshold value of the overall score rate difference of the previous test, the server device 20 is used. You may highlight the bar graph corresponding to the test in which the overall score rate difference is greater than or equal to the threshold value than the overall score rate difference of the previous test.

(3) Processing Flow FIG. 10 is an example of a flowchart showing a procedure of result display processing executed by the server device 20 in the first embodiment. The server device 20 repeatedly executes the process of the flowchart of FIG.

First, the server device 20 determines whether or not a display request related to the result list screen has been received from the terminal device 10 (step S10). The above-mentioned display request includes, for example, identification information of a class to be instructed by a teacher who is a user of the terminal device 10.

Then, when the server device 20 receives the display request of the grade list screen from the terminal device 10 (step S10; Yes), the server device 20 acquires the test result information of each student belonging to the designated class from the test result DB 27. Then, the server device 20 calculates the grade variation value dR for each student in the target class based on the acquired test result information (step S11). That is, in this case, the server device 20 calculates the total score difference of the latest test and the total score difference of the previous test for each student in the target class, respectively, and from the total score difference of the latest test before that. The value obtained by subtracting the total score difference of the test is calculated as the above-mentioned performance fluctuation value dR.

Then, the server device 20 extracts a student whose grade is substantially lowered or a student whose grade is substantially improved as a warning target student based on the grade fluctuation value dR (step S12). For example, when the server device 20 extracts a student whose grade is substantially lowered as a warning target student, the server device 20 considers a student whose grade fluctuation value dR is equal to or less than a reference fluctuation value which is a negative value as a warning target student. On the other hand, when the server device 20 extracts a student whose grade has substantially improved as a warning target student, the server device 20 considers a student whose grade fluctuation value dR is equal to or greater than a reference fluctuation value which is a positive value as a warning target student.

Then, the server device 20 generates the display data D1 of the grade list screen highlighting the grades of the students subject to the warning, and transmits the display data D1 to the terminal device 10 of the display request source, thereby causing the grades to be sent to the terminal device 10. Display the list screen (step S13). Then, the server device 20 determines whether or not any student whose grade is displayed on the grade list screen is selected (step S14). Then, when none of the students is selected (step S14; No), the server device 20 continuously displays the grade list screen (step S13).

When the server device 20 detects that any student whose grade is displayed on the grade list screen is selected (step S14; Yes), the grade individual screen showing the grade transition for each test for the selected student. Is displayed on the terminal device 10 (step S15). In this case, the server device 20 generates the display data D1 of the grade individual screen based on the test result information for the selected student, and transmits the display data D1 to the terminal device 10, so that the grade individual screen is displayed on the terminal device 10. To display.

Next, the server device 20 determines whether or not any of the tests in which the grades of the target student are displayed in chronological order is selected on the grade individual screen (step S16). Then, when the server device 20 detects that one of the tests has been selected on the individual grade screen (step S16; Yes), the server device 20 indicates the correctness of each question of the target student for the selected test. The list screen is displayed on the terminal device 10 (step S17). In this case, the server device 20 generates the display data D1 of the correct / incorrect list screen for each question by referring to the correct / incorrect information for each question included in the selected test and the test result information corresponding to the target student. By transmitting the display data D1 to the terminal device 10, the correct / incorrect list screen for each question is displayed on the terminal device 10. On the other hand, when none of the tests is selected on the grade individual screen (step S16; No), the server device 20 continues to display the grade individual screen on the terminal device 10 (step S15).

[Modification example]
Next, a modification suitable for the first embodiment will be described. The following modifications may be applied to the above-described first embodiment in any combination.

(Modification example 1)
The server device 20 determined whether or not there was a change in grades by using the difference in the overall score rate as an example of an index of grades in consideration of the grades of all the test takers. Instead of this, the server device 20 may determine the presence or absence of fluctuations in grades using deviation values as another example of a grade index that takes into account the grades of all those who have taken the test. In this case, the server device 20 calculates the variation value of the deviation value of the target test with respect to the deviation value of the previous test as the performance variation value dR. In addition, the server device 20 may determine the presence or absence of fluctuations in grades by using an arbitrary index in which the average value is determined in consideration of the scores of all the persons who have taken the test.

(Modification 2)
The server device 20 may determine whether or not the results of the target test are up or down in consideration of the results of a plurality of past tests.

For example, the server device 20 subtracts the average value of the total score rate difference of a predetermined number of past tests performed immediately before the test from the total score rate difference of the target test, and the value after the subtraction. May be calculated as the performance fluctuation value dR. The above-mentioned predetermined number is set to an arbitrary number of 2 or more, and may be set to include, for example, all the tests performed in the current grade.

As a result, the server device 20 can suitably extract students whose grades are different from the tendency of past long-term grades as warning target students.

(Modification example 3)
In the grade list screens shown in FIGS. 4 to 6, the terminal device 10 provided an item of "alert" in the grade list display field 30 and displayed a black circle in the item to highlight the warning target student. Instead of this, the terminal device 10 may highlight the student to be warned by any method other than providing the item of "alert" in the grade list display field 30.

For example, the terminal device 10 may highlight the record in the grade list display field 30 corresponding to the student to be warned by hatching, edging effect, color coding, or the like. Also in this aspect, the terminal device 10 can preferably make the teacher who is the user of the terminal device 10 recognize the existence of the warning target student.

(Modification example 4)
The terminal device 10 may generate the information corresponding to the display data D1 generated by the server device 20 by itself.

In this case, the terminal device 10 receives necessary information from the test information DB 24 and the test result DB 27 via, for example, the server device 20, and thus performs the same processing as the server device 20 of the first embodiment (for example, FIG. 10). Flowchart processing) is executed. The terminal device 10 may store information corresponding to the test information DB 24 and the test result DB 27 in the storage unit 14 in advance.

Also in this modification, the terminal device 10 generates each display data D1 of the grade list screen, the grade individual screen, and the question-specific correct / incorrect list screen, and the same grade list screen, the grade individual screen, and the question-specific correct / incorrect list as in the embodiment. The screen can be preferably displayed. In this modification, the terminal device 10 is an example of the information processing device in the present invention, and the control unit 16 is an example of an acquisition means, an extraction means, a result display means, and a computer that executes a program.

(Modification 5)
The terminal device 10 may be a terminal used by a lecturer or the like of a private educational institution such as a cram school. In this case, the test information DB 24 and the test result DB 27 record information about the test performed in the private educational institution. Then, by referring to this information, the server device 20 generates each display data D1 of the grade list screen, the grade individual screen, and the question-specific correct / incorrect list screen regarding the test conducted by the private educational institution, and the terminal device 10 Send to. As a result, the terminal device 10 can suitably present the results of the test conducted in the private educational institution to the instructor of the private educational institution.

<Second Embodiment>
In the second embodiment, the terminal device 10 differs from the first embodiment in that the student to be warned is selected based on the long-term tendency of the grade. In the following, the components of the second embodiment that are the same as those of the first embodiment are appropriately designated by the same reference numerals, and the description thereof will be omitted.

In the second embodiment, the terminal device 10 calculates an index showing a long-term tendency of the grade (specifically, the grade considering the grade of all the test takers), and determines the student to be warned based on the index. To do. As a typical example of the above-mentioned index, the terminal device 10 is a slope when the total score rate difference for each test performed in the target grade is linearly approximated by using the least squares method or the like (also referred to as “linear approximate slope SL”). Call.) Is calculated. Then, the terminal device 10 considers that the grade of the target student is on a downward trend when the linear approximate slope SL is equal to or less than a predetermined reference slope. The above-mentioned reference slope is a threshold value for determining whether or not the grade is substantially on a downward trend, and is set to, for example, a predetermined negative value. Similarly, the terminal device 10 considers that the result tends to increase when the linear approximate slope SL is equal to or more than a predetermined reference slope. The above-mentioned reference slope is a threshold value for determining whether or not the grade is substantially on an upward trend, and is set to, for example, a predetermined positive value.

In this way, the terminal device 10 determines the tendency of the grade based on the linear approximate slope SL, so that the grade tends to increase or decrease from a long-term viewpoint, regardless of whether the grade of the latest test is good or bad. Students can be suitably identified as warning target students.

FIG. 11 is an example of a result list screen displayed by the terminal device 10 in the second embodiment.

In the grade list screen shown in FIG. 11, "Alert a person whose grade is declining" is selected in the second designation column 32. In this case, the server device 20 is used in the test (here, mid-term test and final test) of the target subject (here, mathematics) conducted in the target grade (here, 3 years) for each student belonging to the target class. The linear approximate slope SL is calculated based on the score rate of the target students and the score rate of all students. Then, the server device 20 identifies a student whose linear approximate slope SL is equal to or less than a predetermined reference slope having a negative value as a warning target student. In the example of FIG. 11, in the server device 20, each linear approximate slope SL of the student “AAAAA” of the number 1, the student “CCCCC” of the number 3, and the student “EEEEEE” of the number 5 is equal to or less than a predetermined reference slope. Therefore, these students are regarded as warning target students, and black circles are displayed in the corresponding "alert" items. As a result, the server device 20 can preferably make the teacher grasp the students whose grades tend to decrease from a long-term perspective.

Further, when the server device 20 detects that "display only alert target" is selected in the first designated field 31, the server device 20 warns the target as in the result list display field 30 of FIG. 5 described in the first embodiment. The grade list display field 30 displaying only the student records is displayed. As a result, the student who is likely to need guidance can be clearly recognized by the teacher who is the user of the terminal device 10.

As described above, in the grade list screen shown in FIG. 5, the server device 20 grades only the records of the students whose total score rate difference of the test conducted this time is lower than the total score rate difference of the test conducted last time by a threshold value or more. It is displayed in the list display field 30.

FIG. 12 is an example of a grade list screen when "Alert a person whose grade is on the rise" is selected in the second designation column 32.

In this case, the server device 20 detects that "alert a person whose grades tend to increase" is selected in the second designated column 32 (that is, detects predetermined instruction information), and the linear approximate slope SL is positive. A student whose value is equal to or greater than a predetermined reference slope is specified as a warning target student. Then, a black circle is displayed in the "alert" item of the record in the grade list display column 30 corresponding to the student to be warned. In the example of FIG. 12, since the linear approximate slope SL of the student “DDDDDD” of the number 4 is equal to or greater than a predetermined reference slope, the server device 20 regards the student as a warning target student and corresponds to the item of “alert”. Is displaying a black circle. As a result, the server device 20 can preferably make the teacher grasp the students whose grades tend to improve from a long-term perspective.

Similar to the first embodiment, when the server device 20 detects that a record of any student in the grade list display field 30 has been selected, the server device 20 displays the grade individual screen for the student corresponding to the selected record. Display data D1 is generated. Then, the terminal device 10 displays the grade individual screen by receiving the above-mentioned display data D1 from the server device 20.

FIG. 13 is an example of a grade individual screen in the second embodiment. In the example of FIG. 13, the server device 20 detects that the student “EEEEE” of the number 5 is selected on the grade list screen shown in FIG. 11, and refers to the test result information or the like for the student. Display data D1 for displaying the grade individual screen shown in is generated.

In the example of FIG. 13, the terminal device 10 displays graphs G1 to G3 showing the transition of the grades of the target student "EEEEEE" on the grade individual screen based on the display data D1 transmitted from the server device 20. .. Here, the graph G1 is a bar graph showing the results (here, the score rate) of the mid-term test and the final test of the target student "EEEEEE" in the current grade in chronological order together with the overall average. Graph G2 is a line graph showing the transition of the overall score rate difference between the mid-term test and the final test of the target student "EEEEEE" in the current grade. Graph G3 is a linear (primary line) graph showing the transition of the overall score rate difference between the mid-term test and the final test of the target student "EEEEEE" in the current grade.

As shown in FIG. 13, the terminal device 10 shows the transition of the overall score rate difference of each test performed in the current grade of the target student “EEEEEE” by graphs G2 and G3. Here, the server device 20 calculates a linear approximate slope SL which is a slope when the total score rate difference for each test of the target grade is linearly approximated, and graphs a linear graph having the slope of the linear approximate slope SL. It is displayed as G3 on the individual grade screen. By doing so, the server device 20 can suitably present the long-term tendency of the grades of the target student to the teacher who is the user of the terminal device 10 on the grade individual screen.

Further, the bar graph shown by the graph G1 or the line graph shown by the graph G2 can be selected for each corresponding test. When the server device 20 detects that the corresponding part of the bar graph or line graph corresponding to an arbitrary test is selected, the display data D1 for displaying the correct / incorrect list screen for each question regarding the correct / incorrect list for each question of the test. To generate. In this case, the terminal device 10 receives the above-mentioned display data D1 from the server device 20 to display a question-specific correct / incorrect list screen showing the correctness of each question for the target test. In this case, the server device 20 causes the terminal device 10 to display a screen similar to the screen example shown in FIG. 8 described in the first embodiment, for example, as a question-specific correct / incorrect list screen. By displaying the correct / incorrect list screen for each question on the terminal device 10 as shown in FIG. 8, the server device 20 allows the teacher to preferably browse the details of the test selected by the teacher.

Further, when "include the end-of-chapter test" is selected in the fourth designated column 38, the server device 20 displays each graph showing the results including the end-of-chapter test results in chronological order as graphs G1 to G3. To do.

Further, the server device 20 identifies a test in which the overall score rate difference is lower than the total score rate difference of the previous test by a threshold value or more, and the portion of graphs G1 to G3 showing the results of the test is displayed. It may be highlighted on the grade individual screen. Similarly, the server device 20 may highlight the graph portion corresponding to the test in which the overall score rate difference is greater than or equal to the threshold value than the overall score rate difference of the previous test.

Further, on the grade individual screen shown in FIG. 13, a viewpoint-based display button 39 marked as "viewpoint-based display" is displayed. When the server device 20 detects that the viewpoint-based display button 39 is selected, the server device 20 displays a graph showing the transition of the score rate for each viewpoint on the individual grade screen.

FIG. 14 shows a display example of the grade individual screen when the viewpoint-based display button 39 is selected. As shown in FIG. 14, in this case, the server device 20 displays line graphs “G21”, “G22”, and “G23” showing the score rates for each of the three viewpoints included in the target subject (here, mathematics). Each is displayed. Here, the graph G21 shows the transition of the score rate of the viewpoint "knowledge / understanding about quantities and figures", the graph G22 shows the transition of the score rate of the viewpoint "mathematical skill", and the graph G23 shows the transition of the score rate. Viewpoint Shows the transition of the score rate of "mathematical viewpoints and ways of thinking".

Further, the server device 20 calculates a linear approximate slope SL for each viewpoint-specific score rate shown by the graphs G21 to G23, and the linear approximate slope SL is equal to or less than a predetermined reference slope. The graph G23 showing the score rate of "idea" is highlighted by making it a thick line. The above-mentioned reference slope is a negative value, and may be the same value as the reference slope used for determining the warning target student, or may be a different value. As a result, the server device 20 can preferably make the teacher grasp the viewpoint that the grades of the target student are declining in the long term. Similarly, the server device 20 may highlight the graph corresponding to the viewpoint when the linear approximate slope SL is equal to or more than the reference slope which is a predetermined positive value.

FIG. 15 is an example of a flowchart showing the procedure of the result display processing executed by the server device 20 in the second embodiment. The server device 20 repeatedly executes the process of the flowchart of FIG.

Then, when the server device 20 receives the display request of the grade list screen from the terminal device 10 (step S20; Yes), the server device 20 acquires the test result information of each student belonging to the designated class from the test result DB 27. Then, the server device 20 calculates the linear approximation slope SL, which is the slope of the linear approximation with respect to the long-term grade of each student, for each student in the target class based on the acquired test result information (step S21). In this case, the server device 20 calculates, for example, the slope when the total score rate difference for each test performed in the target grade is linearly approximated (that is, the regression line is calculated) for each student, and the linear approximate slope of each student. Calculated as SL.

Then, the server device 20 extracts the students to be warned based on the calculated linear approximate slope SL for each student (step S22). For example, when the server device 20 extracts a student whose grade is declining from a long-term viewpoint as a warning target student, the server device 20 considers a student whose linear approximate slope SL is equal to or less than a predetermined reference slope having a negative value as a warning target student. .. On the other hand, when the server device 20 extracts a student whose grades tend to increase from a long-term viewpoint as a warning target student, the server device 20 considers a student whose linear approximate slope SL is equal to or greater than a predetermined reference slope having a positive value as a warning target student. ..

Then, the server device 20 generates the display data D1 of the grade list screen highlighting the grades of the students subject to the warning, and transmits the display data D1 to the terminal device 10 of the display request source, thereby causing the grades to be sent to the terminal device 10. Display the list screen (step S23). Then, the server device 20 determines whether or not any student whose grade is displayed on the grade list screen is selected (step S24). Then, when none of the students is selected (step S24; No), the server device 20 continuously displays the grade list screen (step S23).

When the server device 20 detects that any student whose grade is displayed on the grade list screen is selected (step S24; Yes), the grade individual screen showing the grade transition for each test for the selected student. Is displayed on the terminal device 10 (step S25). Then, the server device 20 determines whether or not any of the tests in which the grades of the target student are displayed in chronological order is selected on the grade individual screen (step S26). When the server device 20 detects that one of the tests in which the grades of the target student are displayed in chronological order is selected on the grade individual screen (step S26; Yes), the correct / incorrect list for each question for the selected test. The screen is displayed on the terminal device 10 (step S27). On the other hand, when none of the tests in which the grades of the target student are displayed in chronological order is selected on the grade individual screen (step S26; No), the server device 20 continues to display the grade individual screen on the terminal device 10. (Step S25).

Next, a modification of the second embodiment will be described.

The first embodiment, the third modification, the fourth modification, and the fifth modification are also applied to the second embodiment in any combination. For example, based on the above-mentioned modification 1, a case where a deviation value is used instead of the overall score rate difference as an index of the grade considering the grade of the whole person who took the test will be examined. In this case, the server device 20 calculates the slope when the deviation value for each test performed in the target grade is linearly approximated by using the least squares method or the like as the linear approximate slope SL. Further, when the terminal device 10 itself generates the information corresponding to the display data D1 generated by the server device 20 based on the above-described modification 4, the terminal device 10 refers to the test result DB 27 and the like and performs the second implementation. The same processing as that of the server device 20 of the form (for example, the processing of the flowchart of FIG. 15) is executed.

Further, the server device 20 calculates the linear approximate slope SL based on the results of the latest predetermined number of tests, instead of calculating the linear approximate slope SL based on the results of each test performed in the target grade. You may. In this case, the above-mentioned predetermined number is set to be an integer of 2 or more.
