BACKGROUND OF THE INVENTION
  The present invention helps to efficiently manage the results of tests performed on students.Grade processing methodAbout.
[0002]
[Prior art]
In recent years, a decline in students' academic ability has been regarded as a problem. Educators have cited a reduction in “writing opportunities” for students as a factor. For example, most of the quizzes conducted in lectures have shifted to the alternative or mark sheet method from the viewpoint of improving the efficiency of scoring and scoring, and students write their answers in their own sentences. Opportunities are decreasing.
[0003]
Also, in the engineering sector, JABEE (Japanese engineer education certification system) has been spreading recently. JABEE is required to enhance the educational curriculum through frequent implementation of quizzes and to preserve educational materials such as answers and attendance tables for a long period of time. This is not limited to JABEE, but also in FD (University Education Reform: Abbreviation of Faculty Development) currently being implemented at universities.
[0004]
Therefore, in recent years, in order to prevent students from degrading their academic ability, for example, as a part of a lecture at a university, a format that allows students to write their own answers (hereinafter referred to as “choice type” or “mark sheet type”) "It is sometimes called" descriptive expression "as a concept that distinguishes from". "
[0005]
[Problems to be solved by the invention]
However, frequent descriptive tests on dozens or hundreds of students will significantly increase the workload of faculty members to aggregate the scores (eg, input to a ledger or computer). There's a problem.
[0006]
  The present invention has been devised in view of the above problems. Student information and scoring information marked by a student and a grader on a test sheet are acquired as text information by image processing, and this text information is obtained.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a schematic diagram of a result processing system 1 of the present embodiment. The results processing system 1 is configured using a computer 2, an image scanner 3 connected to the computer 2, and a test sheet 4.
[0016]
The computer 2 of the present embodiment includes, for example, a first computer 2A installed in a university office, a second computer 2B installed in a faculty's laboratory, and a mail server 2C. Is illustrated. At least the first and second computers 2A and 2B are connected via a network N provided in the university campus, and in this example, are configured to be able to send and receive data to each other. The network N is connected to the Internet in this example. Thereby, for example, the first computer 2A or the second computer 2B can send an e-mail to the student. The electronic mail is sent from the mail server 2C to the external mail server 2D. The student can access the external mail server 2D with, for example, the mobile phone 10 or the personal computers 11 and 12 and read an e-mail addressed to him / herself.
[0017]
The first computer 2A includes a storage unit 6 made of, for example, a magnetic disk. The storage unit 6 includes areas of a program unit 6a that stores a grade processing program (described later) that performs the grade processing of the present embodiment, and a data unit 6b that stores various types of data. As shown in FIGS. 3 to 6, for example, a student data part D1, a question sentence data part D2, a message data part D3, and a questionnaire sentence data part D4 are stored in the data part 6b in advance.
[0018]
As shown conceptually in FIG. 3, the student data section D1 stores information of students (students) managed by the grade processing system in a database structure in advance. As the information, for example, “student name”, “student ID number”, “study course code”, “e-mail address”, and the like can be included in one record. Such a student data section D1 can be created using a student management database provided in advance in the university.
[0019]
If there is no database as described above, each student can submit the information including his / her name, student ID number, etc. by e-mail in advance, and the student data section D1 can be created by processing this data. . In this case, the body of the e-mail is in a fixed form such as the name of the student on the first line, the student ID (alphanumeric characters) on the second line, and the e-mail address on the third line. Send it. This makes it possible to automatically extract the name, student ID number, etc. from the mail text using a subprogram. When the student data section D1 is created by such a method, it is preferable in that the preparatory work for introducing the system can be made efficient.
[0020]
As shown in FIG. 4, the question sentence data part D2 stores information on problem sentences used in the test. As the information, for example, “question number” and “question sentence” indicating the content of the problem can be included in one record. The question sentence is determined by a teacher, for example. Moreover, although the problem sentence illustrates what was memorize | stored as text information in this example, it may be image information. As will be described later, in the present embodiment, this question sentence is printed on the test paper 4.
[0021]
As shown in FIG. 5, the message data section D3 stores various message information that the teacher wants to convey to the students after scoring the test. As the information, for example, a “message number” and a “message sentence” indicating the contents thereof can be included in one record. The message text can be determined in advance by, for example, a teacher, and can include, for example, information on commentary and / or information on the aim of the test performed. When a test is performed a plurality of times, the message text may be common to all tests, and the message can be changed for each test. In this example, the message sentence is illustrated as being stored as text information (information consisting of a character code, the same applies hereinafter), but may be image information (information consisting of a collection of points, the same applies hereinafter). As will be described later, this message sentence is transmitted to the student using an electronic mail in this embodiment.
[0022]
As shown in FIG. 6, the questionnaire text data section D4 stores questionnaire information that a teacher performs on students during a test. As the information, for example, a “questionnaire number” and a “questionnaire text” indicating the contents thereof can be included in one record. The questionnaire text can be determined in advance by a teacher, for example, and can include information on the content of the lecture, for example. The questionnaire text may be common to all tests when the test is performed a plurality of times, and can be changed for each test. In this example, the questionnaire text is exemplified as text information stored, but it may be image information. As will be described later, in the present embodiment, the questionnaire is printed on the test sheet 4.
[0023]
The image scanner 3 and the printer 5 are connected to the first computer 2A. Various types of image scanners 3 can be employed, but those having an auto sheet feeder capable of continuously reading a plurality of test sheets 4 are preferable. A color scanner is preferable, but it may be monochrome.
[0024]
As shown in FIG. 2, the test paper 4 is a rectangular paper in this example, but the size, material, etc. are not particularly limited. In the present embodiment, an A5 size high quality paper is exemplified. In addition, on one side of the test form 4, a name and other information writing column 4a for writing the student's name and student ID number in letters, an answer writing column 4b for writing the answer in letters, and specific information are written by marks. Examples include a mark sheet column 4c and alignment mark portions 4d1 to 4d5. The test paper 4 can be delivered to a school or the like in a state where the standard style of FIG.
[0025]
The answer writing column 4b is a column in which an answer to the question indicated by the teacher is written in letters by the student. In the present embodiment, the test paper 4b includes a ruled line, but it is of course possible to omit it. The question can be shown to the student using, for example, a blackboard, OHP, oral, separate paper, or even a test paper. For example, a question sentence can be printed in advance in the answer writing column 4b. In this case, it is preferable in that the time and effort of the teacher can be further reduced.
[0026]
In the present embodiment, the mark sheet field 4c includes a student ID number field 4c1 that displays a student ID number as a student information, a grading mark field 4c2 that displays a grading result as a grading information, and a student who is a teacher A questionnaire mark field 4c3 for displaying an answer to a questionnaire (described later) issued from the side, and a message mark field 4c4 for displaying individual message information that the teacher wants to convey to students ing. Each of the marks is a known mark sheet method that is performed by painting the corresponding number in black.
[0027]
In the test form 4, the name and other information writing field 4a, answer writing field 4b, student ID number mark field 4c1, questionnaire mark field 4c3 and questionnaire mark field 4c3 are filled in by students taking the test. On the other hand, the scoring mark column 4c2 and the message mark column 4c4 are entered by, for example, a teacher who is a grader, as well as scoring in the answer writing column 4b.
[0028]
Further, the test sheet 4 of the present embodiment exemplifies a mode in which alignment mark portions 4d1 to 4d5 are included for facilitating specification of the position of the mark sheet field 4c during image processing to be described later. The alignment mark portions 4d1 to 4d5 are rectangular patterns in this example, which are painted with a thickness that can be clearly distinguished from other line drawings or marks in the mark sheet column. This will be described later.
[0029]
Next, a specific procedure of a method (result processing program) for performing the results processing of the present embodiment using the system 1 as described above will be described. FIG. 7 shows a large flow of the result processing method of the present embodiment, and FIG. 8 further illustrates this. In the results processing method of this embodiment, the test processing S1, scoring processing S2, results recording processing S3, results distribution processing S4, and results analysis processing S5 are performed.
[0030]
In the test process S1, as shown in FIG. 8, the test paper 4 is first printed, and then the test is performed. In the present embodiment, the question sentence and the questionnaire sentence are printed on the test sheet 4. The teacher uses the first computer 2A, for example, to select a problem sentence and a questionnaire sentence registered in advance from the question sentence data part D2 and the questionnaire sentence data part D4, and perform a printing process on the test sheet 4 Can do. As a result, the test sheet 4 is printed with the question sentence and the questionnaire sentence in addition to the appearance of FIG. 2 by the printer 5 connected to the first computer 2A. The position where the question sentence and the questionnaire are printed is not particularly limited, and not only the one side but also the back side can be used. When the one side is used, for example, a question sentence can be printed from the first line of the test paper 4b, and a questionnaire sentence can be printed on the last line. A method of marking a student ID number or the like may be written on the back surface of the test paper 4.
[0031]
The test is performed by distributing the test sheet 4 to students. The student writes his / her name and answer to the question sentence in text on the test sheet 4 and writes the student ID number and the answer corresponding to the questionnaire sentence in the mark sheet field 4c with marks (filled). Such a descriptive test allows students to think about their answers in their heads and write them in their own sentences, so it has a greater thinking burden on students compared to alternative or mark sheet tests. As a result, it helps to prevent a decline in academic ability.
[0032]
  In scoring process S2,FIG.As shown, the test paper 4 is collected from the student, and the teacher evaluates the answer. In the present embodiment, the answers written by the students are graded on a scale of 0 to 10, for example. The score as the scoring information is directly written in the answer writing field 4b of the test paper 4 with red ink or the like, and the mark corresponding to the score is filled in the scoring mark field 4c2 (FIG. 13 shows this mark). An example of the test sheet 4 scored in this way is shown). In this embodiment, the teacher selects a message registered in advance by referring to the message data part D3 according to the performance of each student, and marks the message number in the message mark field 4c4.
[0033]
As shown in more detail in FIG. 9, the grade book process S3 includes a step of acquiring image information from the scored test sheet 4 (step S31). The image information is obtained by reading the one surface of the test paper 4 with the image scanner 3. Specifically, one or a plurality of test sheets 4 are set on the sheet feeder or the like of the image scanner 3, and reading is started by the first computer 2A to which the image scanner 3 is connected. Reading is performed on only one side of all the test sheets 4.
[0034]
When reading is completed for all the test sheets 4 (Y in step S32), the first computer 2A stores the image information of the read test sheets 4 in a predetermined folder of the data section 6b (step S33). Thereby, the student's answer described in the answer writing column 4b and the scoring result by the teacher can be acquired as image information. Then, by storing the image information in association with the student information (student ID number), the test paper 4 that is a paper medium can be discarded. This is preferable in that a storage space for the test paper 4 is not required. JABEE and FD regulations often require that educational materials such as answers and attendance tables be stored for a long period of time, but at that time, it is often permitted to store image information read by a scanner as an alternative. Therefore, this image information saving function can reduce the burden of paperwork of teachers. The image information is preferably backed up as a separate medium such as MO, CD-R, or DVD as appropriate.
[0035]
Further, in the grade book processing S3 of this example, the read image information is image-processed, and the "student ID number", the "score", "message number" and "questionnaire answer number" as the scoring results are text information from the mark sheet field 4c. (Step S34). The image processing method for extracting the predetermined text information by extracting the contour of the image from the predetermined region of the image information and comparing the contour with a predetermined figure or conversion table, etc. Can be done. Therefore, the specific contents are not particularly limited. In the present embodiment, since the alignment marks 4d1 to 4d5 are provided on the test paper 4, the alignment mark 4d1 can be used even when noise or misalignment occurs during reading of the image scanner 3. Furthermore, since the position can be appropriately corrected using 4d5, the student ID number, the scoring result, and the like can be read as text information more accurately. When the alignment marks 4d1 to 4d5 are not detected, for example, a reading error can be processed.
[0036]
Next, the first computer 2A determines, for example, whether there is a score mark in the image information (step S35). If the mark is marked, text information indicating the score acquired from the mark is set (temporarily stored) in the memory (step S36). Then, the acquired other text information, that is, the student ID number, the questionnaire response number, and the message number are also set in the memory (step S38), and this is written in the result data portion of the data portion 6b (step S39). Then, the first computer 2A determines whether or not all the image information has been processed (step S40). If the result is affirmative (Y in step S40), the process is ended. If the result of step S39 is negative (N in step S40), the process returns to step S34, and the next image information is subjected to image processing.
[0037]
By the way, when scoring the test paper 4, the teacher usually marks the test paper 4 b with ◯, X, etc. with a red pen or the like, and writes the number in letters. Thereafter, a mark corresponding to the score is filled in the scoring mark column 4c2. This is performed for all the test sheets 4. However, in order to further reduce the administrative procedures, for example, the following method can be adopted.
[0038]
That is, for all the test sheets 4, first, the score is determined by putting a circle, x, etc. in the answer writing column 4b with a red pen or the like, and the numbers are written in the same manner as before. Next, the test sheets 4 that have been scored are overlapped for each of the same points to classify the test sheets 4. Then, the teacher fills and displays only the mark corresponding to the score on only one test sheet 4 that is first read by the image scanner 3 in each bundle of the divided test sheets. In each bundle, the second and subsequent test sheets 4 are not marked. Each bundle is also read by the image scanner 3. On the other hand, if the first computer 2A determines in step S35 that the score is not marked (N in step S35), the score of the test sheet processed immediately before the current image information is adopted, This is set in the memory (step S37). Then, step S38 and subsequent steps are processed.
[0039]
In such a process, it is sufficient to mark only the first sheet for the test sheet 4 having the same score, and the first sheet is automatically marked without marking for the subsequent sheets. The number of points is inherited and set. Therefore, it is possible to further simplify the scoring work of teachers and provide a more user-friendly system.
[0040]
FIG. 10 conceptually shows the grade data portion D5 generated in the data portion 6b by the grade book processing S3 as described above. In the grade data section D5, the student's "student ID number" and "test date" (this information is automatically recorded in advance from the teacher's input or the date of the first computer 2A), scoring in one record The test “score”, the “questionnaire answer number” that the student answered to the questionnaire, the “message number”, and the “image file name” that records the image information of the test are included. Information is created for each student. The data portion D5 is created for each test. As described above, in the grade book processing S3, the scoring result of the test scored by the teacher can be automatically taken into the data part 6b of the computer 2. Therefore, the conventional troublesome manual work that has been transferred to the grade management ledger or spreadsheet software can be made unnecessary. For this reason, even if the written test is frequently performed to improve the academic ability of the student, the result processing can be streamlined, and the burden of the paperwork of the teachers can be reduced.
[0041]
The student's grade obtained as described above can be notified to the student by, for example, grade distribution processing S4. In the grade distribution process S4, an electronic mail 12 as shown in FIG. 11 is created and transmitted based on the information in the grade data section D5. The grade data section D5 does not include the student's name, e-mail address, and message text. For this reason, the first computer 2A can acquire the student's name and e-mail address from the student data section D1, using the “student ID number” of the grade data section D5 as a key. Similarly, the corresponding message text can be acquired from the message data portion D3 using the “message number” of the grade data portion D5 as a key. The electronic mail 12 can be created by combining these pieces of information. In this example, the case of the fifth test is shown.
[0042]
Of course, it is also possible to add an individual message or the like to the electronic mail 12 automatically created in the grade distribution process S4. The image information of the test sheet can be transmitted as an attached file. The e-mail 12 created for each student is sent to the student's e-mail address via the mail server. For example, as shown in FIG. 1, students A to C can read an e-mail 12 addressed to themselves from the external mail server 2D. As a result, it is possible to know the test scoring results even outside the class, enabling quick self-evaluation and further enhancing usability.
[0043]
In the grade analysis process S5, the program unit 6a performs various types of display, calculation, analysis, and the like using information in the data unit 6b according to a predetermined procedure. At this time, as described above, since the student information and the scoring information are stored as text information, such numerical calculation can be easily performed. For example, FIG. 12 shows an initial screen V1 of a test result display that can be displayed on a monitor or the like. In the initial screen V1, the display window includes test subject information 13, a display level 14, average score information 15 indicating test average scores, and list information 16. The list information 16 can be easily displayed using the result data part D5 and the student data part D1.
[0044]
The display level 14 includes, for example, “all” indicating all the results of the tests so far (first to fifth times in the present embodiment) and the first to fifth times as shown in the screen V2 in FIG. It is possible to selectively display “individual” in which one of the above (the fifth time in this example) is displayed. When the display level 14 is set to “whole”, the list information 16 displays scoring results in order of student numbers from the first to the fifth for any subject.
[0045]
When the display level 14 is “individual”, as shown in FIG. 13, in addition to the list display 16, the student image information 17 at the cursor position of the list display 16 can be simultaneously displayed in the display window. . In such an embodiment, not only the score read as text information but also the image information 17 can be confirmed at the same time, so there is no error between the score obtained by image processing and the score at the time of scoring (error Can be corrected in the list display 16), or by analyzing how the student answers, the teacher can obtain information that cannot be grasped only by the score. Such information is particularly useful in ensuring data certainty and in providing individual guidance to students.
[0046]
The list information 16 of FIG. 13 is provided with a sample answer selection button. Sample answers are set in, for example, three stages from rank A to rank C, and ranking is performed for a part or all of each test. This work is performed by a teacher. The specific contents of each rank can be set in various ways.
A) Excellent answer
B) Average answer
C) Answer of the lowest pass line
And so on. Then, after assigning one of the ranks A to C to each test and clicking the button 21 “Extract and save sample answer”, the data of the student selected as the sample answer and the image information of the test sheet are displayed. , Saved as a separate file. In JABEE and FD regulations, it is often required to extract and save sample answers in the long-term storage of educational materials such as answers and attendance tables. Use this function. This can reduce the burden of paperwork on teachers.
[0047]
In FIG. 13, when the “distribution” button of the average score information 15 in the display window is clicked, the program unit 6a calculates a score distribution for the currently displayed test scoring results, which is shown in FIG. Thus, the histogram 18 can be displayed. A numerical display or the like can be used together with or instead of the histogram 18. When “execution” is clicked in the questionnaire analysis information 19 shown in FIG. 12, the program unit 6a can count the questionnaire answer numbers and display a histogram 20 of the questionnaire results as shown in FIG. 15, for example. The results analysis process S5 as described above may be performed by the teacher using the second computer 2B, for example, referring to the data portion 6b of the first computer 2A or using data appropriately copied from the data portion. it can.
[0048]
In the above embodiment, the case where the present invention is applied to college student guidance is given as an example, but the present invention is not limited to such an embodiment, and other than elementary, middle, and high schools, vocational schools or It can also be used in various cram schools. Needless to say, the specific shape and the like of the test paper are not limited to those illustrated, and various aspects can be changed.
[0049]
【The invention's effect】
  As mentioned above,Claim 1In this invention, the scored test form contains student information andScoreAnd are displayed as marks, and student information and scoring information are acquired and stored as text information from the image information of this test formprocessingCan be performed using a computer. Therefore, for example, the work in which the grader manually inputs the test scoring results into the grade management ledger or spreadsheet software can be automated by the computer. As a result, even if a written test is frequently performed for the purpose of improving the student's academic ability, the grade processing can be streamlined, and the burden of the paperwork of the teachers can be reduced. Also, with student informationScoreCan be stored as text information, so that it is easy to perform results management, for example, numerical calculation processing such as calculation of average values and graphing.In addition, for a test sheet in which the score has not been entered, the score of the test sheet processed before that is stored in the storage means. In this case, for example, the scoring work may be performed by bundling test sheets for each same score and marking the scoring information only on the first test sheet of each bundle. Therefore, the work of marking the scoring information can be greatly reduced, and the labor of the grader (teacher) can be further reduced.
[0050]
  Further, as in a second aspect of the invention, the test paper isWhen the student includes an answer writing column in which the answer is described and further includes a step of storing the answer written in the answer writing column in the storage means as image information, the answer actually written by the student is also later This image information can be confirmed. Therefore, it is not necessary to store the test paper as a paper medium, so that the storage space can be reduced. In addition, by storing this image information for 5 years, it is possible to satisfy JABEE regulations.
[0051]
  Further, as in the third aspect of the invention,The test sheet includes an alignment mark portion made of a pattern painted with a thickness that can be distinguished from the mark in the mark sheet column, and the image processing specifies the mark sheet column with reference to the alignment mark. Sometimes, even if the reference position of the image information differs due to the difference in the reading direction or deviation of the test paper, the misregistration can be corrected by referring to the alignment mark, and the mark sheet column can always be identified and image processing can be performed stably. And For this reason, text information can be acquired from image information with high accuracy.
[0052]
  Further, as in the invention according to claim 4,When the computer performs the mail delivery processing for sending the scoring result to the student by e-mail, the student can know the scoring result even outside the class, and the self-assessment can be performed quickly. Can increase.
