Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[overall structure]
FIG. 1 shows the configuration of a test processing system according to an embodiment of the present invention. The test processing system includes a test sheet 10 and a terminal device 30 including a scanner unit 31. During the test, the student uses the pen 5 to write an answer on the test sheet 10. When the test is completed, the test sheet 10 is passed to the teacher. The teacher scores the student's answer written on the test sheet 10 and writes the graded result on the test sheet 10 with the pen 6. The test paper 10 in which the graded result is entered is read by the scanner unit 31 and becomes image data (hereinafter referred to as “read image”), and is sent to the terminal device 30. The terminal device 30 generates a test result image described later based on the read image.

[Test paper]
FIG. 2 shows an example of the test sheet 10. The test paper 10 is a normal paper sheet, and a plurality of problems are printed. The example of FIG. 2 is the test sheet 10 before use, ie, before a student writes in an answer, and ten questions are printed. An answer column 11 is provided corresponding to each question, and the student writes an answer for each question in the answer column 11. In addition, the student writes an answer using a normal pencil, a mechanical pencil, a ballpoint pen, etc. as the pen 5.

  The test paper 10 is provided with a check box 12 for each question. Specifically, the check box 12 is provided corresponding to each answer column 11. In the example of FIG. 2, since two answer columns 11 are provided for question (3) and question (7) respectively, two check boxes 12 are provided for question (3) and question (7) respectively. ing. The check box 12 is provided for capturing a handwritten image (handwritten image) written by the student in the answer column 11. The handwritten image entered in the corresponding answer column 11 is captured only for the question for which the check box 12 is filled with a check. Therefore, for a question whose check box is not checked, the handwritten image entered in the answer column 11 is not captured. In addition, a handwritten image is an example of the answer column image of this invention.

  FIG. 3 shows an example of the test sheet 10 after the student has filled in the answer and the teacher has scored. The handwritten answer of the student is entered in each answer column 11, and the teacher determines the correctness of the answer entered in each answer column 11. If the answer is a correct answer, the teacher writes the judgment result "マ ル (○)" in the vicinity of the answer column 11, and if the answer is a wrong answer, the judgment result "バ (" × ")" or Write a check mark to indicate the correct answer. Furthermore, the teacher puts a check in the corresponding check box 12 for a question whose answer is an incorrect answer. In the example of FIG. 3, since the answers to the questions (1), (5), and (10) are incorrect, the check boxes 12 corresponding to these questions are filled with a check.

  As described above, the check box 12 corresponding to the question in which the student's answer is an incorrect answer is checked, and the handwritten image is taken in only for the answer column 11 in which the student enters an incorrect answer. That is, the check box 12 functions as an entry field for entering an instruction to capture a handwritten image of an answer that has been an incorrect answer. The incorrect answer handwritten image thus captured is reflected on the test result image as described later. Therefore, by looking at the test result image, it is possible to know what wrong answer the student has entered.

[Terminal device]
Next, the terminal device 30 will be described. FIG. 4 is a block diagram showing the configuration of the terminal device 30. As shown in FIG. As illustrated, the terminal device 30 includes a scanner unit 31, a control unit 32, a storage unit 33, a test information database (hereinafter, “database” is abbreviated as “DB”) 34, a test result DB 35, and a display unit 36. . These components are connected to one another by a bus 38.

  The scanner unit 31 optically reads the graded test sheet 10 illustrated in FIG. 3 and generates a read image of the entire test sheet 10. The control unit 32 is configured by a computer such as a CPU, and controls each component of the terminal device 30.

  The storage unit 33 is configured of a memory such as a RAM and a ROM. The storage unit 33 stores programs of various processes executed by the control unit 32. The control unit 32 controls the entire terminal device 30 by executing those programs. Further, the storage unit 33 functions as a working memory when the control unit 32 executes various processes. For example, the read image generated by the scanner unit 31 reading the test paper 10 is temporarily stored in the storage unit 33.

  The test information DB 34 first stores an unfilled test image which is an image of the test sheet 10 before the answer is entered, as shown in FIG. The test information DB 34 stores test information for each type of test paper 10. FIG. 5 shows an example of test information. The test paper 10 is given identification information (ID) of the test paper for each type. The test paper 10 illustrated in FIG. 2 is the test paper 10 of ID = 001, and FIG. 5 shows the test information of the test paper 10. As shown in FIG. 5, the test information includes "question number", "correct answer", "check box coordinates", "answer column coordinates", and "recommended teaching materials". The “question number” indicates the number of the question printed on the test sheet 10. Since ten questions are printed on the test paper 10 illustrated in FIG. 2, the test information includes question numbers (1) to (10).

  The “correct answer” indicates the correct answer for each question, and is prepared for each answer column 11. In the example of FIG. 2, since the question (3) has two answer fields 11, the correct answer “3” to be entered in the first answer field 11 and the correct answer corresponding to the second answer field 11 "600" is prepared separately. The same applies to question (7).

  “Check box coordinates” indicates the position coordinates of each check box 12 on the test paper 10. In the present embodiment, position coordinates on the test sheet 10 are indicated by an XY coordinate system with the upper left corner of the test sheet 10 illustrated in FIG. 2 as the origin. Specifically, the check box coordinates indicate the coordinates of the upper left vertex of each check box 12 and the coordinates of the lower right vertex. For example, in the check box 12 of question (1), the coordinates of the top left vertex are (X11, Y11), and the coordinates of the bottom right vertex are (X12, Y12). As for the questions (3) and (7), since two check boxes 12 are prepared, check box coordinates are also stored for each check box 12.

  “Answer column coordinates” indicates position coordinates of each answer column 11 on the test paper 10. The answer column coordinates are indicated using the same XY coordinate system as the check box coordinates. That is, in the present embodiment, the answer column coordinates are also indicated by XY coordinates with the upper left corner of the test paper 10 illustrated in FIG. 2 as the origin. Specifically, the answer column coordinates indicate the coordinates of the upper left vertex of each answer column 11 and the coordinates of the lower right vertex. For example, in the answer column 11 of question (1), the coordinates of the top left vertex are (X13, Y13), and the coordinates of the bottom right vertex are (X14, Y14). As for the questions (3) and (7), since two answer fields 11 are prepared, check box coordinates are also stored for each answer field 11. As described above, since the check box coordinates and the answer column coordinates are stored in association with each question, when the terminal device 30 detects the check box 12 in which the check has been entered, the corresponding answer column 11 It is possible to immediately know the coordinates of and to obtain a handwritten image of the answer entered in the answer column 11.

  The “recommended teaching material” is prepared for each question, and is information indicating a teaching material to be recommended (recommended) to the student if the student's answer to the question is a wrong answer. In the example of FIG. 5, when the student makes a mistake in the question (1), the teaching material A is the recommended teaching material.

  The test result DB 35 stores the past test results for each student. In the present embodiment, a test result image generated by a test analysis process described later is also stored in the test result DB 35. The display unit 36 is configured by a display device such as a liquid crystal display, and displays a test result image described later.

  In the above configuration, the scanner unit 31 is an example of the image reading unit of the present invention, the control unit 32 is an example of the answer column image acquiring unit and the test result image generating unit of the present invention, and the test information DB 34 is an example of the present invention. It is an example of an information storage part and a teaching material storage part.

[Test analysis process]
Next, test analysis processing will be described. The test analysis process is a process in which the terminal device 30 generates a test result image using the test sheet 10 that has been graded by the teacher. FIG. 6 is a flowchart of test analysis processing. In addition, this process is implement | achieved when the control part 32 of the terminal device 30 runs the program prepared beforehand and controls each component.

  First, the graded test paper 10 exemplified in FIG. 3 is set in the scanner unit 31, and the scanner unit 31 reads the test paper 10 (step S10). As a result, a read image of the graded test sheet 10 is generated and temporarily stored in the storage unit 33.

  Next, the control unit 32 determines whether a check is written in each check box 12 of the test paper 10 based on the read image (step S11). Specifically, first, the control unit 32 reads the identification information (ID) of the test sheet written on the test sheet 10 to identify the test sheet, and accesses the test information DB 34 to test information corresponding to the test sheet. To get Then, the control unit 32 refers to the test information as illustrated in FIG. 5, acquires the check box coordinates of each check box 12 provided on the test paper, and writes a check in the position of each check box 12 It is judged whether it is done or not.

  Next, the control unit 32 determines whether the answer is correct or incorrect based on the presence or absence of a check on the check box 12 and generates a scoring result (step S12). In this embodiment, since the teacher is to write a check in the corresponding check box 12 for a question whose answer is a student's answer, the student's answer is incorrect for the question in which the check is written. It will be the answer. Therefore, the control unit 32 determines that the answer to the question is an incorrect answer, and the check is not entered (hereinafter, "no check is made.") The answer of the question is judged as the correct answer, and the graded result including the correctness of the student's answer for each question and the total score etc. is generated. In addition, this method has the advantage that false recognition can be reduced compared with the method of image recognition of the circle (x) and cross (x) image which the teacher filled in on the test sheet to judge the correctness of each question. is there.

  Next, the control part 32 takes in the handwritten image of the corresponding answer column 11 about the question with a check (step S13). Specifically, for a question with a check, the control unit 32 refers to the answer column coordinates in the test information illustrated in FIG. An image of the area of the answer column 11 is acquired. Since the scanned image of the entire test sheet 10 has already been generated by the scanner unit 31 in step S10, the control unit 32 here uses the scanned image of the entire test sheet and the portion of the answer column 11 corresponding to the question with check. Processing of cutting out the image of. Thereby, the handwritten image of the part of the answer column 11 is acquired about all the questions in which the check box 12 is filled with the check.

  In this way, when the handwritten image of the answer column 11 corresponding to the graded result and the question with check is prepared, the control unit 32 generates a test result image using them and displays it on the display unit 36 (step S14) . FIG. 7 shows an example of a test result image. The test result image is generated based on an unfilled test image which is an image of the unfilled test sheet 10 illustrated in FIG. Specifically, based on the presence or absence of the check obtained in step S12, the control unit 32 first makes a false answer mark 13 indicating that the question with the check has a wrong answer with respect to the unfilled test image. It appends and adds the correct answer mark 14 which shows that it is a correct answer about the question without a check. In the example of FIG. 7, although the wrong answer mark 13 and the correct answer mark 14 are added to the position of the question number (the position of "(1)", "(2)", etc.), the target question is clear. If it is, it may be displayed at another position. Further, the control unit 32 additionally writes a total score of 15 ("7/10 points") on the upper right of the test result image based on the scoring result generated in step S12.

  Moreover, the control part 32 inserts the handwritten image acquired by step S13 in the answer column 11 in a blank test image about the question with a check. In this example, since questions (1), (5), and (10) are incorrect answers, a handwritten image written by a student is displayed in the answer column 11 corresponding to them. On the other hand, since the question without check is a correct answer, the control unit 32 refers to the test information illustrated in FIG. 5 and inserts a correct answer for each question. As a result, as shown in FIG. 7, the actual handwritten image of the student is displayed as it is in the answer column 11 for the question that was an incorrect answer, and the correct answer is given by the computer font in the answer column 11 for the question that was a correct answer. Is displayed. This makes it possible to display the handwritten answer actually written by the student as it is for the question that is an incorrect answer. On the other hand, there is no need to acquire a handwritten image for a question that is a correct answer, so the data volume of the test result image can be reduced by omitting the capturing of the handwritten image.

  Furthermore, the control part 32 displays the recommendation information 16 which shows the recommendation teaching material contained in test information, about the question which was an incorrect answer. For example, in the example of FIG. 7, question (1) is an incorrect answer, and thus the recommendation information 16 "recommend teaching material A!" Is displayed with reference to the test information illustrated in FIG. The same applies to questions (5) and (9) that were incorrect. By displaying the recommendation information 16, it is possible to propose appropriate teaching materials to the student in accordance with the question that is the wrong answer.

  Thus, when the test result image is displayed, the test analysis process ends. The generated test result image is stored in the test result DB 35 in association with the student ID. The teacher may print out the test result image and distribute it to the students as needed. In addition, based on a plurality of test results stored in the test result DB 35, statistical information of test results can be generated for each student or for each specific group such as a class or an entire school.

[Modification]
(Modification 1)
In the above embodiment, the teacher writes the check in the check box 12 for the question for which the student's answer was an incorrect answer, but may also check the check box 12 for the question that is the correct answer. . In this way, even if the question is a correct answer, the teacher can display the handwritten image of the answer actually written by the student at the position of the answer column 11 of the test result image. Therefore, it becomes possible for a teacher to display a student's handwritten image and to make a comment on it as a subject, and to discuss it in the whole class. The check box 12 in this case has a function of instructing whether or not to capture a handwritten image of the answer written by the student in the answer column 11. In this case, since the correctness or incorrectness of the student's answer can not be determined based on the presence or absence of the check in the check box 12, a method of image recognition of the marking result of the circle or cross written on the test sheet 10 by the teacher It is necessary to perform processing to determine correctness / incorrectness of the student's answer by character recognition of the answer entered in the answer column 11 by the student and comparing it with the correct answer contained in the test information.

(Modification 2)
Although the terminal device 30 is configured as a stand-alone type computer device in the above embodiment, the server may have the function of the terminal device 30 other than the scanner unit 31 instead. In that case, the teacher scans the graded test sheet using a client terminal used at home or the like and a scanner, and transmits the obtained read image to the server. The server executes the test analysis processing described above using the read image transmitted from the client terminal of the teacher, generates a test result image, and transmits the image to the client terminal of the teacher. The teacher can display and print the test result image sent from the server and use it.

(Modification 3)
In the test paper 10 illustrated in FIG. 2, when there is a plurality of answer fields 11 in one question, a check box 12 is provided for each answer field. For example, for the question (3), since there are two answer fields 11, two check boxes 12 are also provided. Instead of this, even when there are a plurality of answer fields 11, one check box 12 may be provided for one question. In this case, if all the answers entered in the plurality of answer fields 11 are correct, the answer to the question may be determined as the correct answer, and the necessity of the check in the check box 12 may be determined.
