[Display wrong answer tabulation screen]
First, the incorrect answer counting screen displayed by the teacher's terminal 30 will be described. FIG. 3 is an example of an initial display of an incorrect answer tabulation screen regarding a test (here, the first semester mathematics final test) conducted in a certain class (here, 1st grade 2). The teacher's terminal 30 displays the incorrect answer total screen shown in FIG. 3 based on the display data D2 received from the management server 20. FIG. Here, the teacher's terminal 30 displays a test designation field 40, a question-by-question summary table 41, an individual display selection field 42, and a time display selection field 43 on the incorrect answer total screen.

The test specification column 40 is a pull-down menu type input column for specifying a test to be displayed, and accepts input specifying a test to be displayed. The teacher's terminal 30 transmits the input information in the test designation field 40 (in this case, information designating mathematics for the first semester final test) to the management server 20, thereby generating display data for displaying the question-by-question summary table 41. D2 is received from the management server 20.

The problem-by-question summary table 41 is a table showing correct/incorrect information of the students for the test designated by the test designation field 40. and an individual display column 46 showing correct/incorrect information for each question.

In the example of FIG. 3, the teacher's terminal 30 displays the number of incorrect answers of the students in the target class aggregated for each question on the tally display column 45, and also displays the number of wrong answers with the largest number of wrong answers (here, question 1-1 The number of incorrect answers “6”) is highlighted. In addition, the teacher's terminal 30 displays, in the lower right of each column indicating the number of incorrect answers in the tally display column 45, The average value of all students is displayed.

In addition, the teacher terminal 30 displays in the individual display column 46 the items of "nen-gumi" indicating the grade of each student, "number" indicating the student number in the class, and "name" indicating the name of the student. For each student specified by , the total score of the target test, and the correct/incorrect information and stagnation time corresponding to each question from "Question 1-1" to "Question 3-1" are displayed. In the example of Fig. 3, the correct/wrong information is "○" for correct questions, "X" for incorrect questions, "None" for unanswered questions, and "None" for absentees. "-" is displayed for the corresponding question.

In addition, when the individual display selection field 42 labeled "Display name" is unchecked, the teacher terminal 30 hides the individual display field 46 regardless of whether the time display selection field 43 is checked. and hide each student's name and errata information. In addition, when only the time display selection column 43 labeled "Display time" is unchecked, the teacher's terminal 30 displays a Hide the display of the stagnation time for each question.

Here, a supplementary description will be given of the processing of the management server 20 in the display of FIG. When the management server 20 receives input information in the test designation field 40 from the teacher terminal 30, it refers to the test result DB 28 for test result information corresponding to the target test of each student of the target year group. As a result, the management server 20 recognizes the correct/incorrect information and the stagnation time for each question of each student, and generates the display data D2 of the incorrect answer total screen including the question-by-question total table 41 shown in FIG.

When generating test result information for each test to be registered in the test result DB 28, the management server 20 digitizes the content entered in the answer column of each question by OCR, and stores the digitized answer in the test information DB 24. Each question is judged correct or incorrect by comparing it with the correct answer. Then, the management server 20 shows the answer information including the digitized answer for each question and the answer before digitization (that is, stroke information for reproducing the handwriting of the answer) for each test and student, and the correct/wrong judgment result. Test result information that associates at least the correctness information and the score information is generated and recorded in the test result DB 28 .

FIG. 4 is a display example of an incorrect answer counting screen when the number of incorrect answers "6" corresponding to question 1-1 is selected. Here, as an example, the individual display column 46 is hidden by unchecking the individual display selection column 42 .

In this case, the teacher's terminal 30 displays an answer example list 47 in which each student's answer example (answer classification) for the selected question (here, question 1-1) is arranged in descending order. Here, the teacher's terminal 30 displays, as the example answer list table 47, the combinations of the digitally displayed answer examples and the number of people who gave answers belonging to the answer examples, in descending order of the number of people. In this way, the teacher's terminal 30 can suitably display the tallied result of each student's answers to the question selected by the user.

In addition, the teacher's terminal 30 clearly indicates substantially the same answer examples (here, "5x+8y" and "8y+5x") that differ only in the order in which the items are written. 50 are colored in different colors. Furthermore, the teacher's terminal 30 displays the answer examples for the absentee and the no-answer as "absent" and "no answer" respectively in the answer example list 47, and for the correct answer example, the correct answer example is displayed. “(Correct)” is attached so that it can be understood.

Further, below the answer example list 47, check boxes 48a to 48d for determining the display contents of the answer example list 47 are provided. Here, the check box 48a is a column for specifying whether or not to display the correct answer example, the check box 48b is a column for specifying whether or not to display the incorrect answer example, and the check box 48c is a column for specifying no answer. This is a column for designating whether or not display is necessary, and the check box 48d is a column for designating whether or not to display absentees. FIG. 5 is a display example of the wrong answer tabulation screen when the check boxes 48a, 48c, and 48d other than the check box 48b for specifying whether to display the wrong answer examples are unchecked. In this case, since only the check box 48b for designating whether to display the incorrect answer example is checked, the teacher terminal 30 displays the incorrect answer example and the answers belonging to the incorrect answer example as the answer example list table 47. Display only combinations with the number of people who performed In this way, the teacher's terminal 30 can display only specific answer examples in the answer example list 47 based on the user's operation.

Here, a supplementary description will be given of the processing for generating the display data D2 of the incorrect answer tabulation screen shown in FIG. In the test result DB 28, test result information including digitized answers for each question, answer information indicating answers before digitization, correct/incorrect information, etc. is recorded for each student and each test. Therefore, the management server 20 classifies each student's digitized answers to the target questions recorded in the test result DB 28 for each answer example, and totals the number of people who gave answers belonging to each answer example. In this case, the management server 20 classifies each student's answer for each answer example by regarding answers with the same character string obtained by OCR as answers belonging to the same answer example. Then, the management server 20 generates the display data D2 of the answer example list 47 based on the tallied result, and transmits the display data D2 to the teacher terminal 30 . In addition, when the management server 20 detects example answers that differ only in the arrangement order of the terms in the formula, the management server 20 regards these as example answers with substantially the same content, and displays different colors in the classification display column 50 of the example answers. Display data D2 of the colored answer example list 47 is generated, and the display data D2 is transmitted to the teacher terminal 30. FIG.

Further, when an arbitrary example answer is selected from the example answer list table 47, the teacher terminal 30 displays a list of handwriting representing the answer before OCR processing classified into the selected example answer to identify the corresponding student. Display with information.

FIG. 6 is a display example of an incorrect answer counting screen when the answer example "5x+8y" is selected. Here, as items to be displayed in the handwriting list table 49, the teacher terminal 30 displays a "number" indicating the class number of the student who answered the answer example corresponding to the selected classification display column 50, and the class number of the student. "Name" indicating the name and "Answer" indicating the answer of the corresponding student before OCR processing are displayed. As a result, the teacher who operates the teacher terminal 30 can preferably check the actual student's answer corresponding to the arbitrary answer example displayed in the answer example list 47 by using the handwriting list 49 .

In addition, in the process of recognizing the answer, the teacher terminal 30 can display the answer example list 47 not only for descriptive questions that require OCR, but also for multiple-choice questions that do not require OCR. is possible. FIG. 7 is a display example of an incorrect answer tallying screen displaying a list 47 of answer examples for question 2 of the alternative type. In this example, the teacher's terminal 30 detects that Question 2 in the question-by-question summary table 41 has been selected, and provides an answer example indicating a combination of an answer example to Question 2 and the number of people who gave answers belonging to the answer example. A list 47 is displayed. Here, question 2 is an alternative question that does not require OCR for correct/incorrect judgment. In this case, the teacher's terminal 30 displays the answer example list 47 in which the classification display column 50 is not provided.

FIG. 8 is a flow chart showing display processing of an incorrect answer tabulation screen.

First, the teacher's terminal 30 receives an input designating a test to be displayed on the incorrect answer tabulation screen (step S10). After that, the teacher's terminal 30 displays an incorrect answer counting screen showing correct/incorrect information for each question regarding the test specified in step S10 (step S11). Specifically, the teacher's terminal 30 displays an incorrect answer total screen in which the total number of incorrect answers for each question is displayed in the total display field 45, and correct/incorrect information for each question for each student is displayed in the individual display field 46. . In this case, the teacher's terminal 30 transmits the input information received in step S10 to the management server 20, and the management server 20 extracts the necessary test result information from the test result DB 28 based on the input information, thereby displaying the display data. D2 is generated, and the display data D2 is transmitted to the teacher's terminal 30. FIG.

Next, the teacher's terminal 30 determines whether or not any question has been selected on the incorrect answer counting screen (step S12). Then, when the teacher terminal 30 determines that any question has been selected on the incorrect answer tallying screen (step S12; Yes), the answer example belonging to the answer example of the selected question is given. An answer example list 47 is displayed together with the number of people (step S13). In this case, the management server 20 receives the information of the question specified in step S12 from the teacher terminal 30, and each student's answer to the target question recorded in the test result DB 28 has the same character string. Each answer is regarded as an example answer to be displayed with the classified character string. Then, the management server 20 generates display data D2 for displaying the answer example list 47 by counting the number of people for each answer example showing the classified answers, and sends the display data D2 to the teacher terminal 30. Send. On the other hand, when none of the questions is selected (step S12; No), the teacher terminal 30 continues to display the wrong answer tabulation screen in step S11.

Next, the teacher's terminal 30 determines whether or not a specific example answer has been selected in the example answer list 47 (step S14). Then, when the teacher terminal 30 determines that a specific example answer has been selected (step S14; Yes), it displays a handwriting list 49 in which the selected answer examples are listed for each student (step S15). As a result, the teacher's terminal 30 suitably displays the handwritten answer together with the student's identification information. On the other hand, when none of the example answers displayed in the example answer list 47 is selected (step S14; No), the teacher terminal 30 ends the processing of the flowchart.

In the process of displaying the wrong answer tallying screen described above, the management server 20 is an example of an information processing device, and the control unit 23 and the like of the management server 20 include classification means, recognition means, correctness determination means, transmission means, display It is an example of means and a computer that executes a program.

[Display test progress screen]
Next, the test progress screens (the first test progress screen and the second test progress screen) displayed by the teacher's terminal 30 will be described.

FIG. 9A is a display example of the first test progress screen showing the transition of the test results of a certain student "Jiro Dainippon" during a predetermined period. Here, the teacher's terminal 30 displays a population selection button 51 (51a, 51b), a period selection field 52 (52a, 52b), a detail designation link 53, and a display switching button 54 on the first test progress screen. , a rank transition graph 55 and a score rate transition graph 56 are displayed.

Here, the population selection button 51 is a button for specifying the population when displaying the ranking of the target student in the ranking transition graph 55, and for specifying the class to which the target student belongs as the population. It includes a class designation button 51a and a grade designation button 51b for designating all classes in the same grade as the target student as a population. In the example of FIG. 9, since the class designation button 51a is in the selected state, the teacher terminal 30 displays the rank transition graph 55 of the target student's rank transition within the class. The period selection column 52 is a column for specifying the period of the test results to be displayed in the form of a pull-down menu. and a selection column 52b. The teacher's terminal 30 displays the test results for the period specified by the period selection field 52 using a rank transition graph 55 and a score rate transition graph 56 .

The detail designation link 53 is a hyperlink for displaying a window for designating a test to be displayed among the tests within the period designated in the period selection field 52 . FIG. 9B is a display example of a window displayed when the detail specification link 53 is selected. On the window shown in FIG. 9B, a check box is provided for each test within the period specified in the period selection column 52, and it is possible to specify whether or not to display the test.

The display switching button 54 is a button for switching the display to a second test progress screen, which will be described later, showing test results for each unit. The ranking transition graph 55 is a line graph showing the ranking of the target student in each test within the period specified in the period selection column 52 . Further, when the teacher's terminal 30 detects that the mouse is over an arbitrary vertex of the polygonal line, it displays the rank of the target student in the test corresponding to the vertex. In FIG. 9A, the teacher's terminal 30 detects the mouse-over of the top of the ranking transition graph 55 corresponding to the ninth test, and displays the class ranking of the target student in the ninth test in a balloon 57. ing. The score rate transition graph 56 is a bar graph showing the score rate of the target student in each test within the period specified in the period selection column 52 . The teacher's terminal 30 highlights a bar graph representing a score rate lower than the average score rate in the population (class or grade) designated by the population selection button 51 . Here, the teacher's terminal 30 displays in blue a bar graph representing the score rates of the tests (here, tests other than the 6th test) that are above the average score rate, and the tests that are below the average score rate (here, The bar graph representing the score rate of the 6th test) is displayed in red.

When a period is designated by the start period selection field 52a and the end period selection field 52b, the teacher's terminal 30 transmits the information of the designated period to the management server 20 together with the identification information of the student designated in advance. In this case, the management server 20 generates the display data D2 by extracting the target test result information from the test result DB 28 based on the student information and period information received from the teacher terminal 30, and generates display data D2. D2 is sent to the teacher's terminal 30. Then, the teacher's terminal 30 receives the display data D2 from the management server 20 and displays the first test progress screen shown in FIG. 9(A).

FIG. 10 is a first display example of the second test progress screen displayed when the display switching button 54 of the first test progress screen in FIG. 9A is selected. In the first display example of the second test progress screen, the teacher's terminal 30 displays a test selection column 58, a score rate display column 60, and a score rate display table 61 for each unit.

The test selection field 58 is a pull-down menu input field for selecting a test to be displayed. The score rate display field 60 indicates the score rate of the target student (here, "Jiro Dainippon") for the test specified in the test selection field 58 (here, mathematics for the first semester final test of the third year).

The score rate display table 61 for each unit is a table showing the score rate for each unit (category within the subject) included in the test to be displayed, together with the score rate for other completed tests. 62a, a unit display field 62b, a unit score rate display field 62c, and a score rate history display field 62d. Here, the major question display column 62a is a column for displaying the major questions of the test to be displayed, and the unit display column 62b is a column for displaying the units to which the major questions displayed in the major question display column 62a belong. is. The unit score rate display column 62c is a column for displaying the score rate for each unit of the test to be displayed.

The score rate history display column 62d displays the titles and score rates of questions (major questions or small questions) belonging to the same unit as the unit displayed in the unit display column 62b among the questions of the tests that the target student has taken in the past. is displayed in chronological order. Here, the teacher's terminal 30 displays the combinations of titles and score rates side by side so that the questions included in the test with the shortest number of days after the implementation are displayed at a higher rank. If there is a question without a title, the teacher's terminal 30 may display the question number of the question instead. Furthermore, when the teacher's terminal 30 detects that the mouse is over an arbitrary title in the score rate history display field 62d, it displays the date and time when the test including the question of the title was conducted. In the example of FIG. 10, the teacher's terminal 30 detects that the mouse has been moved over the title "similar graphics", so it sets the execution date "April 19" of the test including the question titled "similar graphics". The balloon 63 shown is displayed.

Here, a supplementary description will be given of the process of generating the display data D2 of the second test progress screen shown in FIG.

The test result DB 28 stores test result information for each student and test, and the test result information includes information on the test implementation date, unit information for each question, and score rate information for each question. ing. Therefore, when the management server 20 receives the input information accepted by the test selection column 58 from the teacher terminal 30, by referring to the test result information on the target test from the test result DB 28, the main question display column 62a, the unit Display data for the display column 62b and the unit score rate display column 62c are generated.

In addition, the management server device 20 refers to the test result information about other tests conducted by the target student to determine the score rate of the questions belonging to the same unit as the major questions of the test specified in the test selection field 58. Get information. Then, the management server 20 generates the display data of the score rate history display field 62d by arranging the acquired score rates of the questions in chronological order of the test execution time for each unit to which the main questions included in the target test belong. do. Information related to the title or question number of each question displayed together with the score rate in the score rate history display field 62d is recorded in at least one of the test information DB 24 and the test result DB 28. FIG. Thus, the management server 20 can suitably generate the display data D2 for displaying the second test progress screen shown in FIG.

According to the first display example of the second test progress screen shown in FIG. 10, the teacher preferably displays the score rate for each unit of the target test of the target student together with the results of other tests including questions of the same unit. It becomes possible to refer to it.

FIG. 11 is a second display example of the second test progress screen displayed when the display switching button 54 of the first test progress screen in FIG. 9A is selected. In the example of FIG. 11, the second test progress screen shows the target student's score rate for each unit in the test conducted during the specified period. In this case, on the second test progress screen, the teacher terminal 30 displays a period selection field 64 for designating the period for which the test results are to be displayed, and a subject selection field for designating the subject for which the test results are to be displayed. 65, an average score rate display column 66, and a unit score rate display table 67 are displayed.

The average score rate display field 66 is a field for displaying the average score rate of the subject (here, mathematics) selected in the subject selection field 65 in the period (here, third year, first semester) specified in the period selection field 64. .

The unit score rate display table 67 is a table showing the score rate for each unit of the subject selected in the subject selection column 65 in the period specified in the period selection column 64 (here, the first semester of the third year). It includes a display field 68a, a unit average score rate display field 68b, and a score rate history display field 68c.

Here, the unit display column 68 a is a column for displaying the unit included in the test of the subject selected in the subject selection column 65 during the period specified in the period selection column 64 . The unit displayed in the unit display field 68a may be switchable by user input. In this case, the teacher's terminal 30 may display a window in which checkboxes are arranged for each candidate unit to be displayed in the unit display field 68a, for example, as in FIG. 9B. The unit-by-unit average score rate display column 68 b is a column for displaying the average score rate for each unit of the subject selected in the subject selection column 65 in the period specified in the period selection column 64 . Similar to the score rate history display column 62d in FIG. 10, the score rate history display column 68c displays questions belonging to the same unit as the unit displayed in the unit display column 62b among the questions of the tests that the target student has taken in the past. This is a column for displaying titles and score percentages in chronological order.

In the example of FIG. 11, the management server 20 refers to the test result information regarding the test specified in the period selection field 64 and the subject selection field 65, thereby classifying each test question in the target period for each unit. Then, the management server 20 generates display data for displaying the unit-by-unit score rate display table 67, based on the classified question score rate for each unit and the execution date of the test to which each question belongs. Then, the teacher's terminal 30 displays a second display example of the second test progress screen shown in FIG. 11 based on the display data generated by the management server device 20 . As a result, the teacher terminal 30 can suitably display the score rate history for each unit of the target student.

FIG. 12 is a flow chart relating to a first display example of the second test progress screen shown in FIG.

First, the teacher's terminal 30 receives an input designating a student and a test to be displayed on the incorrect answer tabulation screen (step S20). The teacher's terminal 30 then transmits information about the designated student and the test to the management server 20 . Thereafter, the management server 20 refers to the test result information DB 28 based on the specified student and test information to recognize the unit for each major question of the target test (step S21). Then, the management server 20 refers to the target student's test result DB 28 to extract questions included in other completed tests belonging to each unit recognized in step S21, and calculates the score rate of the extracted questions. The test units are arranged in chronological order according to the date of the test (step S22). The management server 20 generates the display data D2 of the second test progress screen based on the processing result of step S22, and transmits the display data D2 to the teacher terminal 30. FIG. Then, based on the display data D2 received from the management server 20, the teacher terminal 30 arranges the score rate of the target test for each major question and the score rate of the past test of the same unit as each major question in chronological order. A second test progress screen is displayed (step S23).

FIG. 13 is a flow chart regarding a second display example of the second test progress screen shown in FIG.

First, the teacher's terminal 30 accepts an input designating the target period for displaying the students to be displayed and the test results on the incorrect answer tallying screen (step S30). The teacher's terminal 30 then transmits information about the designated student and the test to the management server 20 . After that, the management server 20 refers to the test result information of the corresponding test from the test information DB 24 based on the information of the specified student and the target period, thereby classifying each question of the test within the target period for each unit. , the score rates of the classified questions are arranged in chronological order for each unit in accordance with the execution date of the test (step S31). The management server 20 then generates the display data D2 of the second test progress screen and transmits the display data D2 to the teacher terminal 30 . Then, based on the display data D2 received from the management server 20, the teacher terminal 30 displays the second test progress screen that displays the score rate and average score rate of each question in the test within the target period for each unit ( step S32).

In the process of displaying the second test progress screen described above, the management server 20 is an example of an information processing device, and the control unit 23 and the like of the management server 20 execute reference means, classification means, display means, and programs. It is an example of a computer that

[Display of answer reproduction screen]
Next, the answer reproduction screen displayed by the teacher's terminal 30 will be described. FIG. 14 is a display example of an answer reproduction screen that reproduces the answer of a certain student "Jiro Dainippon". The teacher's terminal 30 has answer selection columns 70a to 70c and an answer reproduction area 71 on the answer reproduction screen.

The answer selection fields 70a to 70c are fields for designating a test, a subject, and a question for specifying an answer to be reproduced and displayed in a pull-down menu format. The teacher's terminal 30 displays, on the answer reproduction area 71, strokes indicating the target student's answer to the question specified by the answer selection fields 70a to 70c together with the corresponding question sentence. The teacher's terminal 30 transmits the information specified by the answer selection fields 70a to 70c to the management server 20 together with the student's identification information specified in advance. In this case, the management server 20 extracts target test result information from the test result DB 28 and extracts target question information from the test information DB 24 based on the information received from the teacher's terminal 30 . The extracted test result information includes stroke information for reproducing the handwriting of the target student's answer to the target question. The management server 20 then generates the display data D2 based on the information extracted from the test result DB 28 and the test information D24, and transmits the generated display data D2 to the teacher's terminal 30. FIG. Then, the teacher terminal 30 receives the display data D2 from the management server 20 and displays the answers to the questions specified by the answer selection fields 70a to 70c on the answer reproduction area 71. FIG.

Here, the management server 20 groups each stroke to be displayed on the answer reproduction area 71 according to a predetermined rule, and classifies each grouped group by color according to the stagnant time required for entry, and displays it on the teacher's terminal. 30. In the example of FIG. 14, the longer the stagnation time, the darker the group, and the shorter the stagnation time, the lighter the group. In this case, the management server 20 regards a block whose stagnation time is equal to or longer than the threshold time as an answer stagnation part, and displays it in the most conspicuous color such as red (the darkest color in the figure). The above threshold time may be a predetermined number of seconds, and is a number of seconds based on the average stagnation time of the entire answer displayed on the answer reproduction area 71 (for example, 2 seconds from the average stagnation time). It may be the number of seconds based on the average stagnation time including other students' answers to the same question. Also, the stagnation time for each group may be, for example, the sum of the stagnation times for the strokes for each group, or the average time for the stagnation times for the strokes for each group. Since the information on the stagnation time for each stroke is included in the test result information recorded in the test result DB 28, the management server 20 can refer to the test result information for the target test to determine the stagnation time for each group. Time can be calculated.

Next, the grouping determination method will be specifically described with reference to FIG. 15 . Below, the management server 20 recognizes the handwriting based on the stroke information as a character string by OCR, and performs one of the following determination methods (first determination method to third determination method) on the recognized character string. By applying this, it is possible to determine groups that should be displayed in the same color.

FIG. 15(A) is a diagram clearly showing each grouping when judging grouping based on the first judgment method for part of the answers reproduced on the answer reproduction area 71 . Here, groups of strokes displayed in the same color are indicated by subscript parentheses, and portions where answers are stagnant are indicated by broken-line frames.

In the first determination method, the management server 20 extracts brackets "(" and ")" and operators "+" and "-" from character strings recognized by OCR, and converts these extracted characters (symbols) to Stroke grouping is performed as a criterion. Here, the operators "+" and "-" are regarded as one group by themselves, and the brackets "(" and ")" together with other characters are regarded as one group.

Specifically, the management server 20 regards the character string “=(a ³ ” before the operator “+” as one group, and the operator “+” as one group. considers the character string "b ³ )" after the operator "+" to the parenthesis ")" as one unit, and regards the character string "=(a ³ ” as one group. Further, the management server 20 regards the operator “-” as one group, and the character string “b ³ )” after the operator “-” as one group. Here, since it is obvious that the "=" at the beginning of the line is written in the calculation of the equation, the following "(a ³ " is regarded as one unit.

Then, the management server 20 calculates the stagnation time for each group, and determines the display color of each group according to the calculated stagnation time. Here, the management server 20 regards the character strings “=(a ³ ” and “b ³ )” as stagnation points because the stagnation time is equal to or longer than the threshold time, and displays them in the most conspicuous color.

FIG. 15(B) is a diagram clearly showing each grouping when judging grouping based on the second judgment method for part of the answers reproduced on the answer reproduction area 71 . In the second determination method, the management server 20 classifies the character strings recognized by OCR based on the brackets "(" and ")" and the operators "+" and "-", and the operator "+" , "-" and parentheses "(", ")" are regarded as one unit. As for the "=" at the beginning of the line, since it is obvious to enter it in the calculation of the equation, "=" and "(" are exceptionally regarded as one group. The server 20 regards a group of a plurality of characters such as "a ³ " and "b ³ " as one group, and can clearly indicate the stagnant part of the answer by color-coding each group. In the example, the management server 20 determines that the three points of “=(”, “(”, and “b ³ ” are the stagnant answer points and highlights them.

FIG. 15(C) is a diagram clearly showing each grouping when judging grouping based on the third judgment method for part of the answers reproduced on the answer reproduction area 71 . In the third determination method, the management server 20 divides the recognized character strings based on brackets "(" and ")". Specifically, the management server 20 regards the character string “=(a ³ +b ³ )” including the first set of parentheses and “=” at the beginning of the line as one unit, and further includes the following set of parentheses. Consider the string "(a ³ -b ³ )" as another group. In this way, when the management server 20 detects a set of parentheses by OCR, the management server 20 regards the set of parentheses and the character string entered between the parentheses as a group to be displayed in the same color. As a result, the management server 20 can color-code each large group, and suitably suppress the complication of the display. In addition, in the example of FIG. 15C, the management server 20 determines “=(a ³ +b ³ )” as an answer stagnant portion and highlights it.

FIG. 16 is a flowchart relating to display processing of an answer reproduction screen executed by the management server 20 .

First, the teacher's terminal 30 receives an input for designating an answer to be displayed (step S40). Then, the teacher's terminal 30 transmits to the management server 20 a display request for an answer reproduction screen including the input information.

Next, when the management server 20 receives a display request for an answer reproduction screen from the teacher terminal 30, the management server 20 refers to the test result information corresponding to the test specified by the display request from the test result DB 28, and displays it. A stroke representing the handwriting of the target answer (that is, the answer including the writing of the process of deriving the answer) is extracted (step S41). The management server 20 then recognizes the extracted strokes as character strings, and divides the recognized character strings into predetermined groups based on operators, parentheses, and the like included in the character strings (step S42). Then, the management server 20 calculates the stroke stagnation time for each group divided in step S42 (step S43). Then, the management server 20 determines the display color of the stroke indicating the handwriting of the answer for each cluster determined in step S42 according to the calculated stagnation time (step S44). Then, the management server 20 generates the display data D2 and transmits the display data D2 to the teacher terminal 30 that requested the display of the answer reproduction screen. Based on the display data D2 received from the management server 20, the teacher's terminal 30 displays an answer reproduction screen in which the strokes indicating the handwriting of the target student's answer are color-coded for each group (step S45).

Note that the management server 20 may highlight only the block determined as the stagnant answer part by coloring it in a different color from the other strokes. For example, the management server 20 may display clusters determined as stagnant answers in a conspicuous color such as red, and may display other clusters in a normal color such as black. This also allows the management server 20 to allow the observer to preferably grasp where the answers are stagnating.

Similarly, the management server 20 may color-code the strokes indicating the handwriting of the target student's answer for each group of answers for subjects other than mathematics. For example, in the case of an answer written in Japanese, the management server 20 divides the character string recognized from the handwriting of the target student's answer by punctuation or the like included in the character string, and classifies each divided group into the above example Calculate the stagnation time in the same way as In this way, the management server 20 can also perform a color-coded display according to the stagnation time for each segmented group, so that the observer can preferably grasp the point where the answers are stagnant.

In the process of displaying the answer reproduction screen described above, the management server 20 is an example of an information processing device, and the control unit 23 and the like of the management server 20 include acquisition means, recognition means, classification means, calculation means, display means, and an example of a computer that executes a program.

[Display answer input keyboard]
Next, an answer input keyboard, which is a software keyboard for inputting answers displayed on the tablet 10b, will be described. FIG. 17 is a display example of the tablet 10b when display of test questions and input of answers (including writing for deriving answers) are performed on the tablet 10b. In the example of FIG. 17, the tablet 10b displays questions 1 to 3 and answer columns 73 to 75 for the questions 1 to 3 based on the display data D3 received from the management server 20. FIG. In addition, blank spaces other than the answer columns 73 to 75 and question sentences can be written with the touch pen 10c. ing.

In the example of FIG. 17, the tablet 10b detects that the answer column 73 has been selected and displays an answer input keyboard 76 for inputting to the answer column 73. FIG. Here, the answer input keyboard 76 has an input content display field 77 , an answer input key 78 for designating characters etc. to be input in the answer field, and an enter button 79 . The input content display column 77 is a column for displaying the input result by the answer input key 78 . The answer input key 78 is a key (button) for inputting an answer, and is composed of different combinations of keys for each question as described later. In the example of FIG. 17, as the answer input keys 78, in addition to input keys for each number, input keys for symbols x and y appearing in the question sentence, input keys displaying "minutes" for displaying fractions, A special key labeled “Others” for further displaying input keys not appearing on the answer input key 78 is arranged on the answer input keyboard 76 . The decision button 79 is a button for reflecting the input content displayed in the input content display column 77 in the answer column (here, the answer column 73).

Here, display processing of the answer input keyboard 76 will be described. First, the tablet 10b transmits to the management server 20 a request to display the answer input keyboard 76 designating the test (here, first semester final exam mathematics) and question (here, question 1) corresponding to the selected answer column. . Here, the test information DB 24 includes, as test information, information on the answer input keys 78 arranged on the answer input keyboard 76 (also called "key arrangement information") for each question.

Therefore, when receiving the display request from the tablet 10b, the management server 20 refers to the test information DB 24 based on the information received from the tablet 10b, and associates the selected answer field with the test and question corresponding to the selected answer column. Get the key mapping information specified. Then, the management server 20 generates the display data D3 of the answer input keyboard 76 in which the answer input keys 78 designated by the key layout information referred to from the test information DB 24 are arranged, and transmits the display data D3 to the tablet 10b. . Accordingly, the tablet 10b can suitably display the answer input keyboard 76 suitable for inputting into the selected answer column based on the display data D3 received from the management server 20. FIG. In this case, the student using the tablet 10b can use the answer input keyboard 76 shown in FIG. 17 to suitably input the answer to question 1 with the touch pen 10c.

FIG. 18 is a display example of the tablet 10b when the answer column 74 for Question 2 is selected. In the example of FIG. 18, the teacher's terminal 30 displays the answer input keyboard 76 for inputting the answer to the answer column 74 because it has detected that the answer column 74 for question 2 has been selected. The configuration of the answer input keys 78 for inputting the answer to the answer column 74 is different from the configuration of the answer input keys 78 for inputting the answer to the answer column 73 shown in FIG. Specifically, the answer input keys 78 shown in FIG. 18 include keys for inputting the symbols “a” and “b” described in the question sentence of Q2. Also, since Question 2 includes multiplication of high-dimensional variables, it includes many keys for inputting degrees. Therefore, the student who takes the test can suitably input the answer to Question 2 using the answer input keyboard 76 and the touch pen 10c shown in FIG.

In addition, instead of determining the display of the answer input keys 78 by referring to the key arrangement information stored in advance in the test information DB 24, the management server 20 uses OCR to display the characters in the process of deriving the answer input to the tablet 10b. Recognition may determine the display of the answer input key 78 .

For example, the management server 20 pre-stores information defining the range of the entry space provided for each question in the test information DB 24 or the like in advance, and refers to the information to determine whether the entry space for each question has been filled in. Extract strokes. Then, the management server device 20 recognizes the extracted stroke as a character string by OCR. Then, when an arbitrary answer column is selected, the management server 20 classifies and classifies the characters included in the character string written in the question entry space corresponding to the selected answer column for each identical character. An answer input key 78 corresponding to each character is displayed. According to this aspect, the management server 20 can display the answer input keyboard 76 preferably including the answer input key 78 for inputting characters input by the student.

In another example, if the character string entered in the entry space is a mathematical formula and the mathematical formula extends over multiple lines, the management server 20 may include the formula in the last line (“=9x+3y” in the example of FIG. 17) The answer input key 78 may be configured based on the characters that appear.

In yet another example, the management server 20 may select the answer input key 78 based on the characters used in the question sentence corresponding to the selected answer column instead of or in addition to the strokes written in the entry space. may be configured. In the example of FIG. 17, the management server 20 reads characters such as numbers, symbols, fractions, operators, and parentheses from the formula "(6x ² +2xy)÷2/3x" included in the question sentence, and corresponds to the read characters. The answer input key 78 may be displayed on the answer input keyboard 76 .

In yet another example, the management server 20 displays the answer input key 78 when inputting a new answer field based on the answer input key 78 used when inputting an answer field in which an answer has already been input. may be determined. For example, the management server 20 displays common answer input keys 78 such as numbers and operators on the answer input keyboard 76 when selecting the answer column of question 1 to be answered first. If the answer input key 78 does not have a keyboard corresponding to the characters used for the answer, the student selects the "Others" button to display other keys as appropriate. Then, when selecting an answer column for question 2 and subsequent questions, the management server 20 adds the answer input keys 78 corresponding to the characters entered in the already entered answer columns to the answer input keys 78 in the initial array, and adds the answer input keyboard. displayed on 76. Also in this aspect, the management server 20 can preferably display the answer input keyboard 76 in which different answer input keys 78 are arranged for each question to be answered.

FIG. 19 is a flow chart relating to display processing of the answer input keyboard 76 .

First, the tablet 10b displays the test that the student should take (step S50). In this case, for example, the tablet 10b transmits a predetermined display request to the management server 20, and receives the display data D3 generated by the management server 20 with reference to the test information DB 24 based on the display request, thereby performing the test. display.

Next, the tablet 10b determines whether or not any answer column has been selected (step S51). When the tablet 10b detects that one of the answer columns has been selected (step S51; Yes), the tablet 10b displays the answer input keyboard 76 in which the answer input keys 78 corresponding to the question in the selected answer column are arranged.

The time (here, 40 seconds) and the erase amount (here, 0 strokes) to the figure area 80 are shown. The stagnant time after writing to the figure area 80 described above indicates the total time of the stagnant time from the end of writing of each stroke written in the figure area 80 to the beginning of writing of the next stroke. The outside-graphic area analysis column 87 is a column for displaying the entry state of the stylus 10c in the outside-graphic area 81, and the amount of writing to the outside-graphic area 81 (35 strokes in this case) and the amount of writing to the outside-graphic area 81 , and the amount of erasing to the non-graphic area 81 (here, 4 strokes). The stagnant time after writing to the non-graphic area 81 described above indicates the total amount of stagnant time from the end of writing of each stroke written in the non-graphic area 81 to the beginning of writing of the next stroke.

In this case, the management server 20 refers to the test information DB 24 for information defining each range of the graphic area 80 and the non-graphical area 81, and extracts stroke information indicating strokes written and erased in each area from the test result DB 28. do. Then, the management server 20 recognizes the strokes written and erased in the graphic area 80 and the non-graphical area 81 based on the stroke information corresponding to each of the graphic area 80 and the non-graphical area 81, and The amount of writing, the stagnant time, and the amount of erasing, which are indices representing the state of writing in , are aggregated. Then, the management server 20 displays the above-described indices relating to the state of writing in the graphic area 80 and the non-graphical area 81 in the graphic area analysis column 86 and the non-graphical area analysis column 87, respectively, and also displays information on the description situation. , and recorded in the test result DB 28 .

The advice display field 88 is a field for displaying advice according to the state of description in the graphic area 80 and the non-graphical area 81 . The management server 20 stores in advance a table (also referred to as an "advice determination table Ta") that associates fixed phrases of advice with display conditions for the advice. , based on the state of description in the graphic area 80 and the non-graphical area 81, the advice to be displayed is determined. A method of determining advice will be described later.

The graphic area reproduction button 89 is a button for displaying the strokes written in the graphic area 80 in chronological order based on the writing time. When the graphic area play button 89 is selected, for example, the teacher terminal 30 hides all the strokes displayed in the graphic area 80 of the answer image 84, and then reproduces the graphic area based on the entry time associated with each stroke. The strokes to 80 are replayed in chronological order. The extra-graphic area reproduction button 90 is a button for displaying the strokes written in the extra-graphic area 81 in chronological order based on the writing time. When the extra-graphic region play button 90 is selected, for example, the teacher terminal 30 hides all the strokes displayed in the extra-graphic region 81 of the answer image 84, and then the stroke information corresponding to each stroke includes Based on the time information, strokes to the non-graphic area 81 are reproduced and displayed in chronological order.

FIG. 23 is an example of an advice determination table Ta that the management server 20 refers to. As shown in FIG. 23, in the advice determination table Ta, advice display conditions are associated with advice to be output when the advice display conditions are satisfied. Advice display conditions are based on indicators (writing amount, stagnation time, erasing amount) indicating each description status in the graphic area 80 and the graphic area 81 displayed in the graphic area analysis column 86 and the graphic area analysis column 87. It is a condition.

The item of advice display conditions in FIG. 23 defines a condition based on at least one of the indicators displayed in the graphic area analysis column 86 and the graphic area analysis column 87 . Advice associated with an advice display condition is advice that is suitable when the corresponding advice display condition is satisfied, and indicates trends and countermeasures regarding descriptions in the graphic area 80 or the non-graphical area 81 . Note that the advice determination table Ta shown in FIG. 23 is stored in advance in the test information DB 24, the test result DB 28, or the like.
