  Exemplary embodiments of an information providing method, an information providing program, and an information providing apparatus according to the present invention will be described below in detail with reference to the accompanying drawings. In the present embodiment, a class is taken as an example, and a class progressor is described as a teacher and a class attendee is described as a student.

  1 and 2 are explanatory diagrams illustrating an operation example of the information providing apparatus according to the present invention. In the system 100 shown in FIG. 1, an information providing apparatus 101, an apparatus 102 possessed by a teacher, and an apparatus 103 possessed by a student are connected via a network NW.

  The plurality of first electronic data 111 includes, for example, a plurality of pages in which sentences, graphs, tables, and the like are created in a slide format, and page numbers are assigned in order. In the present embodiment, the first electronic data 111 is a teaching material for lessons. The plurality of electronic data is stored in a storage device accessible by each device 103. Second electronic data 112 having the same content as the plurality of first electronic data 111 is stored in a storage device accessible by the device 102. The electronic data may be shared as long as each device 103 and the device 102 can browse with different page switching.

  The device 103 has a display capable of displaying the first electronic data 111, and has an input device capable of operating page switching of the first electronic data 111 and an input device capable of inputting characters. The device 103 has an I / F that can be connected to a field device such as the information providing device 101 or the device 102 via the network NW. Examples of the device 103 include portable terminals such as a notebook personal computer, a desktop personal computer, and a tablet terminal. Here, it is assumed that the device 103 is prepared for each student.

  The device 102 has a display capable of displaying the second electronic data 112, and has an input device capable of operating page switching of the second electronic data 112 and an input device capable of inputting characters. The device 102 has an I / F that can be connected to a field device such as the information providing device 101 or the device 103 via the network NW. Examples of the device 102 include portable terminals such as a notebook personal computer, a desktop personal computer, and a tablet terminal.

  The information providing apparatus 101 detects page switching of the first electronic data 111 due to an operation on the apparatus 103 corresponding to the first electronic data 111. For example, each student operates the input device of the device 103 to switch the page of the first electronic data 111 being displayed. When the page of the first electronic data 111 being displayed changes, the apparatus 103 notifies the information providing apparatus 101 of the identification information of the apparatus 103 and the page number of the first electronic data 111 after the page is switched. . The device 103 may also notify the time when the page switching is detected. For example, the information providing apparatus 101 may detect a page switching of the first electronic data 111 due to an operation on the apparatus 103 by receiving a notification from the apparatus 103.

  Each time the page switching is detected, the information providing apparatus 101 identifies the identification information of the apparatus 103 in which the page switching is detected, the page number after the page switching of the detected first electronic data 111, the detected time, Are stored in the storage device in association with each other. Specifically, for example, the information providing apparatus 101 stores an operation information DB (DataBase) 1300. Here, as described above, since each student has the apparatus 103, in this embodiment, the identification information of the apparatus 103 is the student identification information. For example, each student may input student identification information into the device 103 when the device 103 is used. In the example of FIG. 1, the student identification information is “S001”, “S002”, and “S003”, and the teacher identification information is “T001”. The operation information DB 1300 is realized by, for example, a storage device that can be accessed by the information providing apparatus 101. Examples of the storage device include a RAM (Random Access Memory), an optical disk, and a magnetic disk. A detailed example of the operation information DB 1300 is shown in FIG.

  The information providing apparatus 101 detects page switching of the second electronic data 112 due to an operation on the apparatus 102 corresponding to the second electronic data 112. For example, the teacher operates the input device of the device 102 to switch the page of the second electronic data 112 being displayed. When the page of the second electronic data 112 being displayed changes, the device 102 notifies the information providing device 101 of the identification information of the device 102 and the page number of the second electronic data 112 after the page switching. . The device 102 may also notify the time when the page switching is detected. For example, the information providing apparatus 101 may detect a page switching of the second electronic data 112 due to an operation on the apparatus 102 by receiving a notification from the apparatus 102.

  The information providing apparatus 101 specifies a time within a predetermined time from the time when the page switching of the second electronic data 112 is detected. For each piece of identification information of the apparatus 103, the information providing apparatus 101 corresponds to the identification information of the apparatus 103 corresponding to the time within the predetermined time from the detected time and the same page number as the page number after the page switching. In addition, it is determined whether it is stored in the operation information DB 1300. The predetermined time is determined by the designer of the system 100 and stored in advance in a storage device accessible by the information providing apparatus 101.

  For example, the information providing apparatus 101 performs determination for each page number after page switching. For example, when the page number after the page switching of the device 102 by the operation of the teacher T001 is “p.2”, the time when the page switching is detected is tt1-2. When the page number after the page switching of the apparatus 103-1 by the operation of the student S001 is “p.2”, the time when the page switching is detected is ts1-2. The time ts1-2 is included in a time within a predetermined time from the time tt1-2. Therefore, the information providing apparatus 101 determines that the same page number and time within a predetermined time are stored in association with each other in the operation information DB 1300 for the apparatus 103-1 or the student S001.

  For example, when the page number after the page switching of the device 103-3 by the operation of the student S003 is “p.2”, the time when the page switching is detected is ts3-2. The time ts3-2 is not included in the time within a predetermined time from the time tt1-2. Therefore, the information providing apparatus 101 determines that the apparatus 103-3 or the student S003 is not stored in the operation information DB 1300 in association with the same page number and time within a predetermined time.

  The information providing apparatus 101 outputs a determination result. As an output format, for example, a page number and a student ID may be associated with each other and stored in the tracking situation DB 1600. The tracking situation DB 1600 is realized by a storage device accessible by the information providing apparatus 101, for example. Examples of the storage device include a RAM, an optical disk, and a magnetic disk. A detailed example of the tracking situation DB 1600 is shown in FIG. Alternatively, the output format may be displayed on the display of the teacher's device 102.

  Thereby, the information providing apparatus can facilitate the distinction between a student who is listening to a class and a student who is not listening to a class.

(Class progress example)
Here, a lesson progress example in the present embodiment will be described with reference to FIGS.

  FIG. 3 is an explanatory diagram showing an example of class progress. In this embodiment, when the teacher switches the page of the electronic teaching material during the class, the student attending the class switches the page of the electronic teaching material following the teacher. Furthermore, in the present embodiment, for example, during the class, the information providing apparatus 101 receives comments such as questions from students about the contents of the class as comment information via the apparatus 103 that each student has. Comment information is accepted for each page number of the electronic teaching material. Furthermore, each comment information is supposed to be content that should be taken up in class if it is content that a plurality of students wonder. Therefore, a specific evaluation is accepted from the student for each comment information. The specific evaluation may be, for example, a “good” evaluation or a “bad” evaluation for the comment information to be evaluated. In the present embodiment, the specific evaluation is a “good” evaluation.

  FIG. 4 is an explanatory diagram illustrating an example of student distinction. For example, the teacher determines the comment information to be taken up in the class according to the evaluation content of the received comment information. At that time, in the case of a comment evaluated by a student who has not listened to the class among a plurality of students taking the class, there is a low possibility that the content should be taken up in the class. For example, if the content is evaluated by a student who has not listened to the class, the comment may have already been resolved in the class. As described above, in the present embodiment, it is determined whether the page switching by the student follows the page switching by the teacher. The following students are students who are listening to the class, and the students who are not following are the students who are not listening to the class.

  Therefore, in the present embodiment, the information providing apparatus 101 specifies comment information evaluated by a student who is following page switching by a teacher. Alternatively, for example, the information providing apparatus 101 may specify comment information input by a student who is following page switching by a teacher. Thereby, the information provision apparatus 101 can provide a teacher with a comment with a high probability of taking up in a class.

As described with reference to FIG. 1, for example, each student operates the input device of the device 103 to switch the page of the first electronic data 111 being displayed. When the page of the first electronic data 111 being displayed changes, the apparatus 103 notifies the information providing apparatus 101 of the identification information of the apparatus 103 and the page number of the first electronic data 111 after the page is switched. . The device 103 may also notify the time when the page switching is detected. For example, the information providing apparatus 101 may detect a page switching of the first electronic data 111 due to an operation on the apparatus 103 by receiving a notification from the apparatus 103.

  Further, for example, the first detection unit 611 may detect an operation on the device 103 for an application other than the first electronic data 111. Here, an application other than the first electronic data 111 is referred to as “another application”. For example, each device 103 detects an operation of the keyboard 509 or the mouse 510 of the own device 103. Each device 103 can determine that the detected operation is an operation for another application if the application currently selected when detected is not an application that displays the first electronic data 111. Then, each device 103 transmits to the information providing device 101 that an operation on the device 103 corresponding to another application has been detected.

  The operation information storage unit 602 displays the identification information of the device 103 in which the page switching is detected, the page number after the page switching of the first electronic data 111 in which the page switching is detected, and the time at which the page switching is detected. The information is stored in the operation information DB 1300 in association with each other. The operation information storage unit 602 is performed every time page switching is detected by the first detection unit 611. In the present embodiment, as described above, a student ID is used as the identification information of the device 103. Further, the operation information storage unit 602 includes a lecture ID, a class ID, and information indicating the operation of the first electronic data 111 in association with the identification information of the device 103 in which the page switching is detected. You may store in operation information DB1300.

  The operation information storage unit 602 is the operation for the identification information, the operation time, and the operation for another application each time the first detection unit 611 detects an operation on the device 103 for another application. Is stored in the operation information DB 1300. In the present embodiment, as described above, a student ID is used as the identification information of the device 103. Furthermore, the operation information storage unit 602 may store a lecture ID and a class ID in association with the identification information of the device 103 on which another application is operated.

  FIG. 13 is an explanatory diagram illustrating an example of the operation information DB. The operation information DB 1300 stores information related to operations performed by the student in the class on the device 103 possessed by the student. The operation information DB 1300 includes fields for student ID, lecture ID, class ID, operation type identifier, teaching material file name, page number, and operation date and time. By setting information in each field, operation information (1301) is stored as a record. The operation information DB 1300 is realized by the RAM 503, the magnetic disk 505, the optical disk 507, and the like.

  In the student ID field, student identification information is registered. In the lecture ID field, lecture identification information is registered. In the class ID field, class identification information is registered. Information indicating whether the operation is for the first electronic data 111 is registered in the operation type identifier field. “Teaching material operation” indicates an operation on the first electronic data 111, and “Other application operation” indicates an operation on another application.

  When the operation type identifier is “learning material operation”, the name of the first electronic data 111 is registered in the learning material file name field. When the operation type identifier is “separate application operation”, (null) is registered in the teaching material file name field. When the operation type identifier is “learning material operation”, the page number of the first electronic data 111 displayed after the page switching is registered in the page number field. When the operation type identifier is “different application operation”, (null) is registered in the page number field. The date and time when the operation was detected is registered in the operation date and time field.

  The second detection unit 614 detects page switching of the second electronic data 112 due to an operation on the device 102 corresponding to the second electronic data 112. As described with reference to FIG. 1, for example, the teacher operates the input device of the device 102 to switch the page of the second electronic data 112 being displayed. When the page of the second electronic data 112 being displayed changes, the device 102 notifies the information providing device 101 of the identification information of the device 102 and the page number of the second electronic data 112 after the page switching. . The device 102 may also notify the time when the page switching is detected. For example, the information providing apparatus 101 receives a notification from the apparatus 102 to detect page switching of the second electronic data 112 due to an operation on the apparatus 102.

  The determination unit 605 specifies from the time when the page switching of the second electronic data 112 is detected to a time within a predetermined time. For each student identification information, the determination unit 605 determines that the student identification information includes a time within a predetermined time from the detected time and a page number that is the same as the page number after the page switching of the second electronic data 112. , It is determined whether or not it is stored in the operation information DB 1300. For example, the predetermined time is a follow threshold in the threshold DB 700 described above. The determination result is stored in a storage device such as the RAM 503, the magnetic disk 505, and the optical disk 507, for example.

  14 and 15 are explanatory diagrams illustrating a determination example. For example, when the teacher operates the device 102 to switch the page of the second electronic data 112, the second detection unit 614 detects the page switching. The second detection unit 614 acquires the current date and time as the date and time when the page is switched. In the example of FIG. 14, the date and time when switching pages is “2011-12-01 10:16:00”.

  The determination unit 605 sets the date and time when the tracking threshold registered in the threshold DB 700 is added to the date and time at the time of page switching of the second electronic data 112 as the monitoring date and time. Since the following threshold is 1 minute, the monitoring date and time is “2011-12-01 10:17:00”.

  Next, the determination unit 605 acquires a student ID from the student management DB 800 based on the lecture ID. The same processing is performed for all the acquired student IDs. In FIG. 14, “S001” is taken as an example. The determination unit 605 extracts, from the operation information DB 1300, operation information 1301 having a lecture ID “K001”, a lesson ID “J002”, a teaching material file name “CMI system”, and a student ID “S001”. .

  For example, the determination unit 605 selects the operation information 1301 with the latest operation date / time from the extracted operation information 1301. The determination unit 605 determines whether the page number of the selected operation information 1301 is the page number after the page switching of the second electronic data 112, and whether the operation date / time is a period from the date / time at the time of page switching to the monitoring date / time. judge. In the example of FIG. 14, since the page numbers do not match, the determination unit 605 determines that “S001” is not currently being followed. The determination unit 605 repeats the same process for each student ID until the monitoring date and time elapses.

  In the example of FIG. 15, the determination unit 605 has a lecture ID “K001”, a class ID “J002”, a teaching material file name “CMI system”, and a student ID “S001” from the operation information DB 1300. Operation information 1301 is extracted.

  For example, the determination unit 605 selects the operation information 1301 with the latest operation date / time from the extracted operation information 1301. The determination unit 605 determines whether the page number of the selected operation information 1301 is the page number after the page switching of the second electronic data 112, and whether the operation date / time is a period from the date / time at the time of page switching to the monitoring date / time. judge. In the example of FIG. 15, since the page numbers match and the operation date / time is included in the period, the determination unit 605 determines that “S001” is following.

  The output unit 610 outputs the determination result by the determination unit 605. The output format may be stored in a storage device such as the RAM 503, the magnetic disk 505, and the optical disk 507, for example. In the present embodiment, for example, output unit 610 stores the determination result in tracking situation DB 1600. Alternatively, as an output format, for example, the determination result may be output on the display of the teacher's device 102 every time the teacher switches pages. Thereby, the teacher can distinguish the student who is attending the class into the student who is currently listening to the class and the student who is not listening by looking at the display of the device 102.

  FIG. 16 is an explanatory diagram showing an example of the following situation DB in the current class. The following situation DB 1600 has fields of a teacher ID, a lecture ID, a class ID, a class implementation date, a teaching material file name, a page number, and a student ID list. By setting information in each field, the following situation information (1601-1 to 1601-4) is stored as a record. The tracking status DB 1600 is realized by the RAM 503, the magnetic disk 505, the optical disk 507, and the like.

  In the teacher ID, identification information of a teacher who performs a lesson is registered. In the lecture ID, lecture identification information is registered. In the class ID, identification information of the current class is registered. In the class implementation date field, the date of class is registered. Based on this date, it is determined whether the determination result in the current class is registered or the determination result in the past class is registered. The names of the first electronic data 111 and the second electronic data 112 are registered in the teaching material file name field.

  In the page number field, the page number after the page switching of the second electronic data 112 by the teacher's operation is registered. In the student ID list, the student information stored in the operation information DB 1300 is associated with a time within a predetermined time from the time when the page switching is detected and the same page number as the page number after the page switching. Identification information is registered.

  According to the tracking situation DB 1600, in the electronic teaching material with the file name “CMI system”, when the page number is 1, the students indicated by “S001” to “S0006” follow the page switching of the teaching material by the teacher, and the teaching material The page has been switched.

  For each page number, the identification unit 608 associates the student identification information stored in the operation information DB 1300 with the same page number as the time within the predetermined time from the comment DB 1100 during the class. Identify information. Thereby, it is possible to extract comment information posted by a student who is determined to be listening to a lesson. Students who are listening to the class are more likely to input comment information that is appropriate for the class than students who are not listening to the class. Therefore, the information providing apparatus 101 identifies the comment information posted by the student who is determined to be listening to the class, so that the teacher can know the comment information with high accuracy to be taken up during the class.

  Further, the identification unit 608 associates each page number with student identification information stored in the operation information DB 1300 in association with the same page number from a time within a predetermined time from the comment evaluation DB 1200. Identify comment information. Here, the identification unit 608 includes, in the student list of the comment evaluation DB 1200, identification information of the student determined to be stored in the operation information DB 1300 in association with the same page number as the time within a predetermined time. It is determined whether or not.

  For example, taking the comment ID “C008” as an example in the comment evaluation DB 1200, the student IDs that evaluated the comment information are “S002”, “S003”, “S006”, and “S007”. The page number of the comment ID “C008” is “4”. In the following situation DB 1600, the student ID list when the page number is “4” is “S001”. When the page number is “4”, the determination unit 605 has not specified any comment information.

  Next, in this embodiment, in the above-described case, the information providing apparatus 101 specifies comment information that is estimated to have high accuracy according to the following situation in the current class. For example, not only the current class but also the follow-up situation in the past class may be used to specify comment information that is estimated to be highly accurate.

  FIG. 17 is an explanatory diagram illustrating an example of a follow-up situation DB in a past class. In the following situation DB 1700, student IDs that follow the progress of the teacher in the past class are registered. The fields included in the following situation DB 1700 are the same as the fields included in the following situation DB 1600, and thus detailed description thereof is omitted. By setting information in each field, tracking status information (1701-1 to 1701-5) is stored as a record. The follow-up situation DB 1700 is realized by the RAM 503, the magnetic disk 505, the optical disk 507, and the like. The following situation DB 1600 shown in FIG. 16 and the following situation DB 1700 shown in FIG. 17 may be one database, but the database may be distinguished for each class.

  For example, in the following situation DB 1600 shown in FIG. 16, the class ID is “J002”, the class implementation date is “2011-12-01”, and the teaching material file name is “CMI system”. In the following situation DB 1700 illustrated in FIG. 17, the class ID is “J001”, the class implementation date is “2011-11-26”, and the teaching material file name is “education information system”.

  The first comparison unit 606 stores each student ID in the tracking situation DB 1700 in association with the page switching count by the teacher's operation in the past class and the page number after the page switching by the student operation indicated by the student ID. Comparison processing is performed with the number obtained. The number of page switching by the teacher's operation in the past class is equal to the number of records having the same class ID and class implementation date in the following situation DB 1700. In the example of the tracking situation DB 1700, it is 5 times. The number stored in the tracking situation DB 1700 in association with the page number after the page switching by the student operation indicated by the student ID is a number included in the student ID list of the record. Taking the student ID “S001” as an example, it is five times because it is registered in all student ID lists with page numbers “0” to “5” in the following situation DB 1700. When the student ID is “S002”, it is 4 times.

  As the comparison process, for example, the frequency of following a lesson may be calculated. Taking the case where the student ID is “S001” as an example, if the class ID is “J001”, the frequency is 100 [%] because the page switching frequency is following 5 times out of 5 times. .

  Furthermore, if the past lesson is performed a plurality of times, the first comparison unit 606 may calculate an average value or standard deviation of the frequencies.

  The determination unit 607 determines, for each student ID, whether the comparison result by the first comparison unit 606 satisfies a predetermined condition. For example, if the comparison result by the first comparison unit 606 is a frequency, the determination unit 607 determines whether the frequency is equal to or greater than a threshold value [%]. For example, when the frequency is equal to or higher than the threshold, the determination unit 607 determines that the predetermined condition is satisfied. Alternatively, for example, if the comparison result by the first comparison unit 606 is the average value and standard deviation of the frequency, the determination unit 607 may determine whether “average value−standard deviation” is equal to or greater than a threshold value. . The “average value−standard deviation” is assumed to be the degree of expectation to follow the course progress stably. The threshold for the degree of expectation is registered in the population extraction threshold in the threshold DB 700. For example, if the degree of expectation is greater than or equal to a threshold value, the determination unit 607 determines that a predetermined condition has been satisfied. For example, the determination unit 607 stores the determination result by the determination unit 607 in the student population DB 1900.

  FIG. 18 is an explanatory diagram illustrating an example of a population extraction process. The first comparison unit 606 selects one student ID of the record whose lecture ID is “K001” from the student management DB 800. In FIG. 18, the student ID is “S001” as an example.

  The first comparison unit 606 creates empty tracking frequency calculation array data 1800. Next, the first comparison unit 606 determines from the following situation DB 1700 the number of records with the lecture ID “K001”, the class implementation date “2011-12-01”, and the class ID “J001” ( Hereinafter, it is referred to as “total number of data”). Here, there are 5 records. The information providing apparatus 101 counts the number of records including “S001” in the student ID list (hereinafter referred to as “following data number”) from the following situation DB 1700. Here, there are 5 records.

  Next, the first comparison unit 606 calculates the number of following data / the total number of data. Then, the first comparison unit 606 sets the calculation result in the tracking frequency calculation array data 1800.

  The first comparison unit 606 calculates the average value of the tracking frequency and the standard deviation of the tracking frequency for each student ID included in the tracking frequency calculation array data 1800. Next, the first comparison unit 606 performs “expectation = average value−standard deviation” for each student ID. Then, the determination unit 607 determines whether the calculated expectation is greater than a population extraction threshold included in the threshold DB 700. The determination unit 607 sets, in the student population DB 1900, a student ID for which the calculated expectation is determined to be greater than the population extraction threshold included in the threshold DB 700.

  FIG. 19 is an explanatory diagram showing an example of the student population DB. The student population DB 1900 has fields for a lecture ID, a class ID, and a student ID. By setting information in each field, student population information (1901-1 to 1901-3) is stored as a record. The student population DB 1900 is realized by the RAM 503, the magnetic disk 505, the optical disk 507, and the like.

  In the lecture ID field, lecture identification information is registered. In the class ID field, identification information of the current class is registered. In the student ID field, the student ID determined by the determination unit 607 as satisfying the predetermined condition is registered.

  The identifying unit 608 determines that each page number is stored in the operation information DB 1300 in association with the same page number as the time within a predetermined time, and it is determined that the comparison result satisfies a predetermined condition. Identify student identification information. The identifying unit 608 identifies, for each page number, comment information associated with the student identification information from the comment evaluation DB 1200. A specific specific example is shown in FIGS.

  FIG. 20 is an explanatory diagram illustrating an example of specifying a student ID to be evaluated. Here, the identified student identification information is a student ID to be counted when counting evaluation results of comment information.

  As described above, the student ID determined by the determination unit 607 that the comparison result satisfies the predetermined condition is registered in the student population DB 1900. For each of the teaching material file name and the page number, the student ID determined by the determination unit 605 to be stored in the operation information DB 1300 in association with the same page number as the time within a predetermined time is registered in the following situation DB 1600. Has been.

  More specifically, the identifying unit 608 extracts from the tracking status DB 1600 tracking status information 1601 having a class ID “J002” and a teaching material file name “CMI system”. The extracted following status information 1601 is shown in the figure. The identifying unit 608 identifies, for each page number, a student ID that matches the student ID registered in the student population DB 1900 among the student IDs in the student ID list of the extracted tracking status information 1601. The student IDs registered in the student population DB 1900 are “S001” to “S003”. For example, when the page number is “1”, the student ID list is “S001” to “S006”. Therefore, the specifying unit 608 specifies “S001” to “S003” when the page number is “1”. The student ID specified here is stored in the specified intermediate information DB 2000.

  The specific intermediate information DB 2000 includes fields for a teaching material file name, a page number, and a student ID list. A student ID specified individually is registered in the field of the student ID list.

  For example, the specifying unit 608 specifies comment information including the student ID registered in the specific intermediate information DB 2000 in the comment evaluation student ID list from the comment evaluation DB 1200.

  FIG. 21 is an explanatory diagram of a specific example of comment information. More specifically, the specifying unit 608 uses the number of student IDs included in the specified intermediate information DB 2000 as the teaching material tracking data parameter based on the page number for each piece of comment information in the comment evaluation DB 1200. For example, when the page number is “1”, the student ID list of the specific intermediate information DB 2000 is “S001” to “S003”. In the comment evaluation DB 1200, the comment IDs with the page number “1” are “C001” and “C003”.

  The teaching material tracking data parameter for the comment IDs “C001” and “C003” is “3”. In the student ID list of the specific intermediate information DB 2000 when the page number is “1”, the “student ID included in the comment evaluation student ID list when the comment ID is“ C001 ”” is “S003”. Therefore, when the comment ID is “C001”, the number of effective comment evaluation students is “1”.

  Among the student ID lists of the specific intermediate information DB 2000 when the page number is “1”, the student IDs included in the comment evaluation student ID list when the comment ID is “C003” are “S002” and “S003”. Therefore, when the comment ID is “C003”, the number of effective comment evaluation students is “2”.

  For example, the specifying unit 608 may specify comment information having a comment evaluation effective student number of 1 or more. The output unit 610 may output the comment information specified by the specifying unit 608. As a result, the teacher can be informed of the comment information evaluated by the student listening to the class.

  Here, the first ID of the student ID stored in the comment evaluation DB 1200 in association with the comment information specified by the specifying unit 608 and stored in the operation information DB 1300 in association with the same page number as the time within a predetermined time. One is the teaching material tracking data parameter. The second number of student IDs determined by the determination unit 607 that the comparison result satisfies the predetermined condition is the number of comment evaluation effective students.

  The second comparison unit 609 performs a comparison process between the teaching material tracking data parameter and the comment evaluation effective number of students for each piece of comment information specified by the specifying unit 608. As the comparison process, for example, “teaching material tracking data parameter / comment evaluation effective number of students” may be calculated.

  The output unit 610 associates and outputs the comment information and the comparison result by the second comparison unit 609 for each piece of comment information specified by the specifying unit 608. In the example shown in the figure, the teaching material tracking data population / comment evaluation effective number of students is set as an evaluation value, and a comment ID and an evaluation value are associated with each comment ID and output to the identification result DB 2100. For example, when the comment ID is “C001”, since “3/1 = 0.33”, “0.33” is registered as the evaluation value. Further, for example, the output unit 610 sets the evaluation value to the comment evaluation effective number in the comment evaluation DB 1200.

  For example, the information providing apparatus 101 may select comment information whose evaluation value is equal to or greater than a threshold value from the specified comment information and output the selected comment information to the teacher-side terminal.

  Thus, when there is a large amount of comment information evaluated by students listening to the class, it is possible to notify the teacher of comment information evaluated by students listening to more classes.

  The first comparison unit 606 stores each identification information of the student in the tracking situation DB 1600 in association with the first page switching number of the device 102 and the same page number as the time within a predetermined time. The second number of times determined to be present is compared. The output unit 610 outputs the comparison result between the first number and the second number by the first comparison unit 606 for each of the student identification information. Thereby, a population can be determined in advance for the next class.

(Procedure for starting and stopping the information providing apparatus 101)
FIG. 22 is a flowchart illustrating an example of a procedure for starting and stopping the information providing apparatus. First, the activation process procedure of the information providing apparatus 101 will be described. The information providing apparatus 101 initializes the event reception process stop flag (step S2201). Specifically, for example, the information providing apparatus 101 sets “not set” in the event reception process stop flag.

The information providing apparatus 101 registers operation information reception processing in the event reception process (step S2204), and registers learning material page follow-up determination processing in the event reception process (step S2205).

  The information providing apparatus 101 registers the student population extraction process in the event reception process (step S2206), and registers the comment evaluation aggregation process in the event reception process (step S2207). Then, the information providing apparatus 101 performs event reception processing by the event reception process (step S2208), and ends the activation of the information providing apparatus 101. About step S2202-step S2207, a process may be performed in parallel.

  Next, a stop processing procedure of the information providing apparatus 101 will be described. The information providing apparatus 101 sets “stop” in the event reception process stop flag (step S2211), and ends the series of processes.

(Event reception processing procedure by the information providing apparatus 101)
23 and 24 are flowcharts illustrating an example of an event reception process procedure by the information providing apparatus. The information providing apparatus 101 determines whether the process stop flag is “stop” (step S2301). When the process stop flag is “stop” (step S2301: Yes), the series of processes is ended.

  When the process stop flag is not “stop” (step S2301: No), the information providing apparatus 101 determines whether an event start instruction is received (step S2302). If an event activation instruction has not been received (step S2302: NO), the process returns to step S2301.

  When the event activation instruction is received (step S2302: Yes), the information providing apparatus 101 acquires the event type of the received event activation instruction (step S2303) and creates empty data of response data (step S2304). The information providing apparatus 101 determines whether or not the event type is “comment post reception processing” (step S2305).

  When the event type is “comment posting reception processing” (step S2305: Yes), the information providing apparatus 101 receives the received student ID, lecture ID, class ID, teaching material file name, page number, comment posting date, and comment information. Is acquired (step S2306). Next, the information providing apparatus 101 performs comment posting reception processing (step S2307), transmits response data to the transmission source of the event activation instruction (step S2308), and returns to step S2301.

  In step S2305, when the event type is not “comment posting reception processing” (step S2305: No), the information providing apparatus 101 determines whether the event type is “comment evaluation reception processing” (step S2309).

  When the event type is “comment evaluation reception processing” (step S2309: Yes), the information providing apparatus 101 acquires the received student ID and comment ID (step S2310), and performs comment evaluation reception processing (step S2311). . Then, the information providing apparatus 101 transmits response data to the transmission source of the event activation instruction (step S2312), and the process returns to step S2301.

  If the event type is not “comment evaluation reception process” in step S2309 (step S2309: No), the information providing apparatus 101 determines whether the event type is “operation information reception process” (step S2401). When the event type is “operation information reception process” (step S2401: Yes), the information providing apparatus 101 receives the received student ID, lecture ID, class ID, operation type identifier, teaching material file name, page number, and operation date and time. Is acquired (step S2402). The information providing apparatus 101 performs operation information 1301 reception processing (step S2403), transmits response data to the user (step S2404), and returns to step S2301.

  If the event type is not “operation information reception processing” in step S2401 (step S2401: No), the information providing apparatus 101 determines whether the event type is “student population extraction processing” (step S2405). . When the event type is “student population extraction processing” (step S2405: Yes), the information providing apparatus 101 acquires the received lecture ID, class ID, and population extraction date (step S2406). The information providing apparatus 101 performs student population extraction processing (step S2407), transmits response data to the transmission source of the event activation instruction (step S2408), and returns to step S2301.

  If the event type is not “student population extraction processing” in step S2405 (step S2405: NO), the information providing apparatus 101 determines whether the event type is “learning page follow-up determination processing” (step S2409). ). When the event type is “teaching material page follow-up determination process” (step S2409: Yes), the information providing apparatus 101 receives the received teacher ID, lecture ID, class ID, class implementation date, teaching material file name, page number, and operation.

The process proceeds to step S3505. When the student ID of the selected following situation information 1601 is not included in the student ID of the student population DB 1900 (step S3503: No), the process proceeds to step S3505. The information providing apparatus 101 determines whether or not all student IDs in the tracking status information 1601 have been selected (step S3505).

  The information providing apparatus 101 acquires the comment evaluation student ID list of the selected comment evaluation information 1201 (step S3506), and selects one student ID from the acquired comment evaluation student ID list (step S3507). The information providing apparatus 101 determines whether or not the student ID in the selected comment evaluation student ID list is included in the student ID of the following status information 1601 and included in the student ID of the student population DB 1900 (step S3508). . When included in any of them (step S3508: Yes), the information providing apparatus 101 adds (+1) the number of comment evaluation effective students (step S3509), and proceeds to step S3510. When it is not included in any one of the information (step S3508: No), the process proceeds to step S3510.

  The information providing apparatus 101 determines whether all student IDs included in the comment evaluation student ID list of the comment evaluation information 1201 have been selected (step S3510). If there is an unselected student ID among the student IDs included in the comment evaluation student ID list of the comment evaluation information 1201 (step S3510: NO), the process returns to S3507. If all student IDs included in the comment evaluation student ID list of the comment evaluation information 1201 have been selected (step S3510: YES), the process proceeds to step S3601.
