DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First Embodiment [Overall configuration] 1 shows the configuration of an education support system to which the education support device of the present invention is applied. In this embodiment, users are teachers and students, and the education support system 1 of the present invention is applied to school classes. The education support system 1 comprises a teacher terminal 15, a management server 20, and a student terminal 30. The management server 20 is capable of communicating with the teacher terminal 15 and the student terminal 30 via wireless communication such as WiFi (registered trademark).

[0016] The teacher terminal 15 is a PC, a tablet, or the like, and is basically used by a teacher. The teacher terminal 15 is connected wirelessly or by wire to a liquid crystal display device or the like installed in a classroom for students to view. Here, the liquid crystal display device is, for example, a television. The teacher connects his / her own teacher terminal 15 to a television, which is a liquid crystal display device, with an HDMI (High-Definition Multimedia Interface; registered trademark) cable or the like, and displays the display screen of the teacher terminal 15 on the television to show to the students. Specifically, the teacher terminal 15 displays textbook data, which is digitized teaching material data, on its own display unit, and also displays the textbook data on the television installed in the classroom. FIG. 2 shows an example of the display of textbook data. The teacher gives a lesson to the students while referring to the textbook data by displaying the same screen as the teacher terminal 15 on a liquid crystal display device such as a television. The student terminal 30 is a PC, a tablet, or the like, which is distributed to each student. The students use the student terminal 30 to study, take tests, and the like.

[0017] The management server 20 is a device that controls the overall operation of the education support system 1, and is connected to a textbook database (hereinafter, “database” will be abbreviated as “DB”) 26 and a question DB 27.

[0018] The textbook DB 26 stores textbook data as teaching material data. The management server 20 reads out the textbook data from the textbook DB 26, transmits it to the teacher terminal 15 used by the teacher and the student terminal 30 used by the students, and displays it. The teacher refers to the textbook data displayed on the liquid crystal display device via the teacher terminal 15 to proceed with the lesson. The question DB 27 stores question data and answer data for the question data. The management server 20 extracts question data from the question DB 27 based on the teacher's input to the textbook data, and creates a test. The management server 20 then displays the created test on the teacher terminal 15 and the student terminal 30.

[0019] [Administration Server Configuration] 3 is a block diagram showing the internal configuration of management server 20. Management server 20 includes a communication unit 21, a log data acquisition unit 22, a keyword setting unit 23, a question data extraction unit 24, and a test creation unit 25. These components, a textbook DB 26, and a question DB 27 are interconnected via a bus 29.

[0020] The communication unit 21 is a communication unit for communicating with the teacher terminal 15 and the student terminal 30 via wireless communication. Specifically, the communication unit 21 transmits textbook data and test data to the teacher terminal 15 and the student terminal 30. In addition, the communication unit 21 receives log data from the teacher terminal 15 regarding input to the textbook data by the teacher.

[0021] The log data is text data corresponding to markings in textbook data or text data written by a user and recognized using an OCR (Optical Character Reader) or the like.

[0022] The textbook DB 26 stores textbook data as teaching material data. The question DB 27 stores question data and answer data for the question data. Fig. 4 shows an example of the data configuration of the question DB 27. Specifically, the question DB 27 stores a question ID which is identification information of the question, question data related to the question, answer data related to the answer to the question, etc.

[0023] The log data acquisition unit 22 acquires, via the communication unit 21, from the teacher terminal 15, log data relating to input by the teacher to the textbook data.

[0024] A teacher can operate teacher terminal 15 to input, for example, underlining or circling important words in textbook data while teaching. Here, marking a word or sentence by underlining or circling it is also called "marking". FIG. 5 shows an example of the display of textbook data with words marked. In the example of FIG. 5, the following parts are highlighted by marking: "Minamoto no Yoritomo", "Feudal System", "Samurai-dokoro", "Manadokoro", and "Monchujo". In this case, log data acquisition unit 22 acquires log data related to the marking of the highlighted words from teacher terminal 15.

[0025] The teacher can also operate the teacher terminal 15 to input sentences, rather than words, by underlining them or encircling them. Fig. 6 shows an example of textbook data with marked sentences. In the example of Fig. 6, the following parts are highlighted by marking: "Kamakura was the first feudal government in Japan, established by Minamoto no Yoritomo" and "It housed the Samurai-dokoro, which organized the vassals, the Mandokoro, which handled general and financial affairs, and the Monchujo, which was a court of law." In this case, the log data acquisition unit 22 acquires log data related to the marking of the highlighted sentences from the teacher terminal 15.

[0026] Although details will be described later, when a student inputs textbook data, the log data acquisition unit 22 may acquire log data from each student terminal 30.

[0027] The keyword setting unit 23 sets keywords based on the log data. Specifically, the keyword setting unit 23 identifies words that the teacher has marked in the textbook data based on the log data and sets them as keywords.

[0028] In addition, when the teacher marks a sentence instead of a word, the keyword setting unit 23 identifies the sentence marked by the teacher based on the log data, and sets the extracted word by morphological analysis of the identified sentence as a keyword. Here, a morpheme is the smallest unit of an expression element having meaning, and morphological analysis is to divide a sentence into morphemes, which are the smallest units, and extract them. For example, a sentence "Kamakura was the first feudal government in Japan established by Minamoto no Yoritomo" is divided into morphemes such as the noun "Minamoto no Yoritomo" and the particle "ga" by morphological analysis and extracted. The keyword setting unit 23 of this embodiment further extracts words important in learning history from the nouns extracted by morphological analysis and sets them as keywords.

[0029] As will be described in more detail later, when log data is acquired from each student terminal 30, the keyword setting unit 23 identifies the words that each student has marked in the textbook data based on the log data of each student, and sets keywords for each student.

[0030] Based on the keyword, the question data extraction unit 24 extracts test question data from the question DB 27. Specifically, the question data extraction unit 24 extracts question data including the keyword as test question data from the question DB 27. In addition, the question data extraction unit 24 extracts question data corresponding to the answer data including the keyword from the question DB 27 as test question data.

[0031] The test creation unit 25 creates a test consisting of test question data, and outputs test data relating to the test to the teacher terminal 15 and the student terminal 30. Specifically, the test creation unit 25 transmits the test data to the teacher terminal 15 and the student terminal 30 via the communication unit 21. The teacher terminal 15 and the student terminal 30 receive the test data from the management server 20 and display the test.

[0032] 7 shows an example of a test display on the student terminal 30. The test is composed of test question data containing keywords in the question data or answer data. For example, if the keywords set by the keyword setting unit 23 are "Minamoto no Yoritomo," "feudal system," "Samurai-dokoro," "Manadokoro," and "Monchusho," questions that make up the test include "Which shogunate did Minamoto no Yoritomo establish?", where the keyword "Minamoto no Yoritomo" is included in the question data, and "What is the name of the institution that controlled the vassals?", where the keyword "Samurai-dokoro" is included in the answer data.

[0033] Note that the test creation section 25 is not limited to outputting test data, but may output test question data to the teacher terminal 15 or the like.

[0034] In the above configuration, the question DB 27 of the management server 20 is an example of a question data storage unit of the present invention. Also, the log data acquisition unit 22, the keyword setting unit 23, the question data extraction unit 24, and the test creation unit 25 of the management server 20 are examples of a log data acquisition unit, a keyword setting unit, a question data extraction unit, and a question data output unit of the present invention, respectively.

[0035] [Test output process according to the first embodiment] Fig. 8 is a flowchart of the test output process according to the first embodiment. In this process, the management server 20 sets keywords based on the teacher's input to the textbook data, and creates and outputs a test consisting of test question data based on the keywords. Specifically, this process is realized by the computer constituting the management server 20 executing a program prepared in advance.

[0036] First, the teacher operates teacher terminal 15 to input important words in the textbook data, such as underlining or circling them, while proceeding with the lesson. Management server 20 acquires log data related to the input to the textbook data from teacher terminal 15 (step S101). Then, management server 20 identifies the words marked by the teacher in the textbook data based on the log data, and sets the identified words as keywords (step S102). Furthermore, management server 20 extracts test question data from question DB 27 based on the keywords (step S103).

[0037] The management server 20 creates a test consisting of one or more test question data, and transmits test data related to the test to the teacher terminal 15 and the student terminal 30 (step S105). The teacher terminal 15 and the student terminal 30 receive the test data from the management server 20, and display the test on their respective display units. This completes the test output process.

[0038] In this way, the management server 20 of this embodiment can set the points marked by the teacher in the teaching material data as keywords while the lesson is proceeding, and output test question data related to the keywords to the teacher terminal 15 and the student terminal 30. In other words, the management server 20 can automatically create tests according to the teaching material data and lesson contents, and provide them to the teacher and students.

[0039] [First Modification] In this embodiment, the keyword setting unit 23 identifies the words marked by the teacher in the textbook data and sets them as keywords. However, the present invention is not limited to this, and the keyword setting unit 23 may set not only the marked words but also synonyms and related words of the marked words as keywords. Here, synonyms are words that have a different form from the marked word but are similar in meaning and may be substituted in some cases. Also, related words are words that have a different form from the marked word in the teaching material data but are related in meaning to each other, and can be set arbitrarily. Specifically, in the case where parent and child and husband and wife are set as related words of person names in the history textbook data, the keyword setting unit 23 also sets "Hojo Masako", the wife of Minamoto no Yoritomo, as a related word of the marked word "Minamoto no Yoritomo" as a keyword.

[0040] [Second modified example] In the education support system 1 in this embodiment, as shown in Fig. 1, a management server 20, a teacher terminal 15, and a student terminal 30 are communicably connected to each other. However, the present invention is not limited to this, and as shown in Fig. 9, an education support system 1x may be configured such that a management server 20, a display board 10, a teacher terminal 15, and a student terminal 30 are communicably connected to each other.

[0041] Here, the display board 10 is a display device using a liquid crystal display device or the like, and is installed in place of or in addition to a blackboard in a classroom. Textbook data, which is electronic teaching material data, is displayed on the display board 10. In this case, the management server 20 reads out the textbook data from the textbook DB 26 and displays it on the display board 10 seen by the students, the teacher terminal 15 used by the teacher, and the student terminal 30 used by each student. In this way, the teacher may proceed with the lesson by referring to the textbook data displayed on the display board 10. In this case, the teacher may mark the textbook data displayed on the display board using an input pen for the display board or the like. In that case, the management server 20 may set keywords based on the words or sentences marked on the display board and create a test.

[0042] [Third Modification] In the present embodiment, the first modification, and the second modification, the teacher uses the teacher terminal 15, but the present invention is not limited to this, and the teacher may use a teacher terminal 50 having the functions of the management server 20. In this case, as shown in Fig. 10, in the education support system 1y, the teacher terminal 50 and the student terminals 30 are connected so as to be able to communicate with each other. The teacher terminal 50 is a PC, a tablet, or the like, like the teacher terminal 15.

[0043] <Second embodiment> Next, a description will be given of an education support system 1 in the second embodiment. Note that since the overall configuration and the configuration of the management server 20 are similar to those in the first embodiment, the description will be omitted for the sake of simplicity.

[0044] In the education support system 1 of the second embodiment, the management server 20 acquires log data on the entries made by each student in the textbook data from each student terminal 30, and sets keywords for each student. Then, the management server 20 extracts test question data from the question DB 27 based on the number of students and the keywords of the students.

[0045] For example, the management server 20 sets a threshold for the number of students who have acquired log data, and when there is an identical keyword as a keyword for students equal to or greater than the threshold, the management server 20 extracts test question data from the question DB 27 based on the identical keyword. Specifically, it is assumed that 35 students out of 40 students have marked the word "Minamoto no Yoritomo" as important. In this case, the management server 20 sets "Minamoto no Yoritomo" as a keyword for the 35 students. When the threshold is set to 20 students, which is half of the total number of students, the management server 20 extracts test question data from the question DB 27 based on the keyword "Minamoto no Yoritomo" set for 20 or more students. In other words, the management server 20 extracts question data whose question data or answer data includes the keyword "Minamoto no Yoritomo" as test question data from the question DB 27. On the other hand, it is assumed that 15 students out of 40 students have marked the word "Monchusho" as important. In this case, the management server 20 sets "Monchusho" as a keyword for 15 students out of 40 students. If the threshold is set to 20, since "Monchusho" is not a keyword set for more than 20 students, the management server 20 will not extract test question data based on the keyword "Monchusho."

[0046] The management server 20 may also aggregate the keywords of each student, set a priority order to the most frequently used keywords among all the students, and extract test question data from the question DB 27 based on the priority order. Specifically, the management server 20 sets "Minamoto no Yoritomo" as the keyword for 35 students, "feudal system" as the keyword for 28 students, "samurai-dokoro" as the keyword for 23 students, and "monchu-sho" as the keyword for 18 students. If the priority order is set to three, the management server 20 sets the first priority order to the keyword "Minamoto no Yoritomo", the second priority order to the keyword "feudal system", and the third priority order to the keyword "samurai-dokoro", and extracts test question data from the question DB 27 based on the first to third priority keywords. That is, the management server 20 extracts, from the question DB 27, question data whose question data or answer data includes any of the keywords "Minamoto no Yoritomo", "feudal system", and "samurai-dokoro" as test question data.

[0047] [Test output process according to the second embodiment] Fig. 11 is a flowchart of the test output process according to the second embodiment. In this process, the management server 20 sets keywords based on the entries made by students in the textbook data, and creates and outputs a test consisting of test question data based on the keywords. Specifically, this process is realized by the computer constituting the management server 20 executing a program prepared in advance.

[0048] First, each student operates the student terminal 30 to mark important words in the textbook data while attending class. The management server 20 acquires log data related to the marking of the textbook data by each student from each student terminal 30 (step S201). Then, the management server 20 identifies the words marked in the textbook data by each student based on the log data, and sets the identified words as keywords for each student (step S202). Furthermore, the management server 20 extracts test question data from the question DB 27 based on the number of students and the keywords of the students (step S203).

[0049] The management server 20 creates a test consisting of one or more test question data, and transmits test data relating to the test to the teacher terminal 15 and the student terminal 30 (step S205). The teacher terminal 15 and the student terminal 30 receive the test data from the management server 20, and display the test on their respective display units. This completes the test output process.

[0050] In this way, the management server 20 in the second embodiment identifies the words marked in the textbook data by each student based on the log data of each student, and sets the keywords for each student. Then, the management server 20 determines, for example, the importance of keywords common to a threshold number of students or keywords that are numerous among all students, and extracts test question data from the question DB 27 based on the keywords with high importance.

[0051] The present invention is not limited to this, and based on the log data of each student, words that are commonly marked by a threshold number of students or words that are frequently marked by all students may be determined to be of high importance, and the keyword setting unit 23 of the management server 20 may set the words of high importance as keywords. In this case, the question data extraction unit 24 extracts test question data from the question DB 27 based on the keywords.

[0052] In this way, the education support system 1 in the second embodiment can acquire log data from a plurality of student terminals 30, set keywords based on the importance of the log data, and then output test question data.

[0053] [Variations] In the second embodiment described above, tests are created based on students' entries in textbook data, but the first and second embodiments may be combined to create tests based on teachers' and students' entries in textbook data. In this case, a weight may be added to the teacher's input to calculate the number of students to be compared with a threshold. For example, the teacher's input may be calculated as the number of students for 10 students, and the number may be compared with a threshold to determine whether or not to use the input for extracting test question data.

[0054] The first to third modified examples in the first embodiment can also be applied to this embodiment in the same manner. [Explanation of symbols]
