  In a class where teachers and students gather together in the classroom as described in Patent Document 2, for example, when a teacher issues a problem and one of the students tries to present an answer, It is easy to find the student who wants to present from the raised hand or the facial expression of the student. In addition, it is easy to encourage individual students to make a presentation without actively making a presentation. Therefore, it is easy to activate the lesson by letting any student present.

  However, in the class using the communication system, the student's facial expression is not known, so if there is no student who wants to present, it is difficult for the student to present and it is difficult to activate the class. This is a structural problem in the communication lesson system.

  It is an object of the present invention to provide a lesson system and lesson support method that can encourage students to present their answers and activate the lesson even if there is no student who wants to announce the answer to the problem. .

The present invention provides a calculation unit that calculates an index indicating the frequency at which students taking a class have announced answers to questions previously issued by the teacher, a storage unit that stores the index, and a new one issued by the teacher. When a student answers a question, the answer is correct, and the frequency of announcing answers to questions previously issued by teachers based on the index stored in the storage unit is below a predetermined threshold An instruction system is provided that includes an extraction unit for extracting students.

In the present invention, the control unit calculates an index indicating the frequency at which a student taking a lesson has announced an answer to a question previously issued by a teacher, the storage unit stores the index, and the control unit includes: Students whose answers to questions newly issued by the teacher are correct and whose frequency of presenting answers to questions previously issued by the teacher based on the index stored in the storage unit is below a predetermined threshold A class support method characterized by extracting

  According to the lesson system and lesson support method of the present invention, even if there is no student who wants to announce an answer to a problem, the student can be prompted to announce the answer, and the lesson can be activated.

  Hereinafter, a lesson system and lesson support method according to an embodiment will be described with reference to the accompanying drawings. Since the lesson system of the present embodiment is preferably a communication lesson system, the lesson support method used in the communication lesson system and the communication lesson system is taken as an example in the present embodiment described in detail below.

  In FIG. 1, the communication class server 10 is connected to a communication line 20. The communication line 20 is an arbitrary communication line such as the Internet. The communication line 20 is connected to a student terminal 30 possessed by a student who is located away from the communication class server 10. In FIG. 1, the number of student terminals 30 is six, but the number of student terminals 30 (that is, the number of students) is arbitrary.

  The student terminal 30 may be any computer device such as a smartphone, a tablet terminal, or a personal computer. The student terminal 30 may be a terminal using virtual reality (VR) or augmented reality (AR). The student terminal 30 using the VR may be a goggle type terminal. As will be described later, each student terminal 30 stores a student application program and is given a student identification code (student ID) for uniquely identifying the student.

  A classroom display 11, a relay camera 12, a teacher terminal 13, a microphone 14, and a speaker 15 are connected to the communication class server 10. The speaker 15 includes headphones (earphones). The place where these devices are installed is called a classroom for convenience. The communication class server 10 may be installed outside the classroom. The teacher terminal 13 may be any computer device such as a tablet terminal or a personal computer.

  As shown in FIG. 2, the teacher 40 stands in front of the classroom display 11 and performs a class using the classroom display 11 and the teacher terminal 13. The classroom display 11 is a large screen display called an electronic blackboard. The teacher 40 performs lessons by displaying lesson data stored in the communication lesson server 10 on the classroom display 11. The lesson data may be displayed on the teacher terminal 13.

  The lesson by the teacher 40 is photographed by the relay camera 12, and the moving image data photographed by the relay camera 12 is distributed by the communication lesson server 10 to each student terminal 30 via the communication line 20. The moving image data may be displayed on the teacher terminal 13. The teacher 40 can give a problem to the classroom display 11.

  The teacher 40 wears a headset in which the microphone 14 and the speaker 15 as a headphone are integrated. The voice uttered by the teacher 40 is picked up by the microphone 14 and can be distributed to each student terminal 30 by the communication class server 10 via the communication line 20. The teacher 40 can listen to the voice of the voice data transmitted from the student terminal 30 via the communication line 20 through the speaker 15.

  The microphone 14 and the speaker 15 may be installed separately. The microphone 14 and the speaker 15 may be provided in the teacher terminal 13.

  Specifically, the communication class server 10 and the teacher terminal 13 are configured as shown in FIG. 3, for example. The communication class server 10 includes a central processing unit (hereinafter referred to as CPU) 101, an image / sound processing unit 102, a storage unit 103, and a communication unit 109. The CPU 101 is an example of a control unit. The storage unit 103 includes a student ID table 104 that associates student IDs and specific student information such as a student name, a student information database (hereinafter referred to as a student information DB) 105 that accumulates information related to classes of each student, and a teacher. Application program 108 is stored.

  The student information DB 105 includes an announcement rate table 106 indicating the announcement rate of each student with respect to the problem issued by the teacher 40, and a correct answer rate table 107 indicating the correct answer rate. The announcement rate table 106 is an example of an index indicating the frequency at which students taking a lesson have presented answers to questions previously issued by the teacher 40. The correct answer rate table 107 can be omitted.

  The student information DB 105 may store more detailed data of each student. For example, the student information DB 105 may store a subject that each student is good or weak, a point that each student is likely to make a mistake, and the like.

  The CPU 101 calculates the student presentation rate and updates the presentation rate table 106. The CPU 101 operates as a calculation unit that calculates an index indicating past learning behavior of a student taking a class. The CPU 101 operates as a calculation unit that calculates an index indicating the frequency of presenting answers as a suitable example of the index indicating the past learning behavior of the student. The CPU 101 calculates the correct answer rate of each student and updates the correct answer rate table 107.

  The image / sound processing unit 102 performs processing such as compression encoding on one or both of the moving image data captured by the relay camera 12 and the sound data collected by the microphone 14. The communication unit 109 transmits moving image data, audio data, or moving image audio data to the student terminal 30. The communication unit 109 may transmit message data or still image data to the student terminal 30.

  The communication unit 109 receives any of moving image data, still image data, audio data, and message data transmitted from the student terminal 30. The image / sound processing unit 102 performs processing such as decompression decoding if the received data is compressed and encoded. The classroom display 11 can display moving image data or still image data images transmitted from the student terminal 30.

  As shown in FIG. 3, the teacher terminal 13 includes an input unit 131 and a display 132. The input unit 131 may be a keyboard or a touch panel integrated with the display 132. The display 132 may display an image of moving image data or still image data transmitted from the student terminal 30. The message transmitted from the student terminal 30 may be displayed on the display 132.

  The teacher 40 can input message data to be transmitted to the student terminal 30 by operating the input unit 131. The teacher 40 can operate the input unit 131 and select message data of a fixed sentence set in advance by the teacher application program 108.

  Specifically, the student terminal 30 is configured, for example, as shown in FIG. The student terminal 30 includes a central processing unit (hereinafter referred to as CPU) 301, a camera 302, an input unit 303, a storage unit 304, an image / sound processing unit 306, a display 307, a microphone 308, a speaker 309, and a communication unit 310. The storage unit 304 stores a student ID and a student application program 305.

  The input unit 303 may be various keys or a touch panel integrated with the display 307. The speaker 309 includes headphones (earphones).

  Here, an example of the announcement rate indicated by the announcement rate table 106 will be described. The teacher 40 gives a question to each student in each class, and prompts the student to make a presentation after the student answers. As an example, as shown in FIG. 5, on the display 307 of the student terminal 30, a raise hand 311 pressed by a student who desires to present is displayed by the student application program 305. When the student presses the raise hand button 311, the student ID of the student who pressed the raise hand button 311 is notified to the teacher terminal 13, and the teacher 40 can recognize the student who wants to present.

  The teacher 40 selects one of the students who pressed the raise hand button 311 and the selected student announces the answer to the question. The method of presenting the answer is arbitrary, and the video and audio data in which the student announces the answer may be transmitted from the student terminal 30 to the communication class server 10, or the voice data is transmitted to the communication class server 10. You may send it.

  As an example, the CPU 101 calculates the announcement rate as shown in FIG. FIG. 6 conceptually shows the announcement rate table 106. In FIG. 6, the number of presentations with respect to the number of classes is simply used as the presentation rate, but the announced time may be reflected in the presentation rate. For example, even if the number of presentations is the same twice, a student who has made two presentations in the first class out of 10 classes and has not made any presentations in the 9th class, and 2 in the 10th class Suppose that there is a student who has announced the times. In this case, the presentation rate may be increased by weighting the latter student's presentation rate more heavily.

  Specifically, by summing up values obtained by multiplying the number of presentations by a coefficient that becomes smaller in the past class, it is possible to obtain a presentation rate reflecting the time of presentation. For example, the coefficient is set to 1 for the presentation of the last two classes, the coefficient is set to 0.8 for the presentation of the previous two classes, and the coefficient is set to 0.5 for the presentation of the previous class. It is possible to do.

  Now, it is assumed that the teacher 40 newly gives a problem to the student in this class. As an example, the student hand-writes the answer to the question on the page, and transmits the still image data obtained by photographing the page with the camera 302 to the communication class server 10 through the communication unit 310.

  In this issue, if students are asked to make a presentation and the student presses the hand raising button 311 to recruit applicants for the presentation, only a specific student who is highly conscious of the presentation as shown in FIG. Is expensive. This makes it difficult for students with a low awareness of presentations to present and activate classes. If there is no student who is highly aware of the presentation, no student may wish to make a presentation and it is difficult to activate the lesson.

  Then, even if there is no student who wants to announce the answer of a problem (or at least), each example of the class support method for encouraging the student to announce the answer and activating the class will be described.

<First example>
In FIG. 7, the teacher 40 operates the teacher terminal 13 and instructs the communication class server 10 to extract students with a low presentation rate (presentation low frequency students) in step S <b> 1. In step S2, the correspondence class server 10 extracts students whose announcement rate is equal to or less than a predetermined threshold from the announcement rate table 106 as shown in FIG. If the threshold value is 10%, a presentation low frequency student is extracted and supplied to the teacher terminal 13 as shown in FIG.

  In the first example, the CPU 101 of the communication lesson server 10 operates as an extraction unit that extracts a specific student based on an index indicating a student's past learning behavior stored in the storage unit 103. As a preferred example, the CPU 101 extracts students whose answer has been announced in the past based on an announcement rate table (an index indicating the frequency of presentation of each student) below a predetermined threshold.

  In step S3, the teacher terminal 13 displays a list of low-frequency presentation students. The teacher 40 operates the teacher terminal 13 to select one of the presentation low frequency students displayed in the list in step S4 and forcibly designate the student to present the answer.

  When any one of the students extracted by the extraction unit is selected (forced nomination) by the teacher, the communication unit 109 transmits notification information that prompts the selected student to make a presentation. The notification information may be message data calling for “please announce”, moving image and audio data, or audio data. As described above, the message data may be a fixed sentence, or a button (icon) similar to the raised hand button 311 may be used as the notification information.

The display 132 of the teacher terminal 13 operates as a presentation unit that visually presents information related to the student extracted by the extraction unit to the teacher. The student information may be a student ID or a student ID and a student name.

<Second example>
In the first example, the announcement low frequency student is extracted regardless of whether or not the student is answering correctly, but as in the second example, the announcement low frequency student is extracted from the students answering correctly. May be. The second example is preferred over the first example.

  In FIG. 7, the teacher 40 sees the answer of each student, and notifies the correct classifier to the communication class server 10 in step S11. The CPU 101 can update the correct answer rate table. At this time, the teacher 40 may notify the communication class server 10 of not only the correct answerer but also the student who made an erroneous mistake worthy to present, although it is an incorrect answer. In step S12, the teacher 40 instructs to extract a presentation low frequency student.

  In step S13, the communication class server 10 extracts, as specific students, students who are correct answerers and whose presentation rate is equal to or lower than a predetermined threshold (correct answer / presentation low frequency students). Here, the teacher 40 notifies the correct answerer to the correspondence class server 10. However, if the correspondence class server 10 can automatically extract the correct answerer as in the case of a selection type question, the correct answer is automatically provided.・ You may extract students with low frequency of presentation.

  In step S14, the teacher terminal 13 displays a list of correct answer / presentation low frequency students. The teacher 40 operates the teacher terminal 13 to select one of the correct answers / presentation low frequency students displayed in the list and forcibly nominate the answer in step S15. Similarly, the communication unit 109 transmits notification information that prompts the selected (forced nomination) student to present.

  In the second example, the extraction unit extracts correct answers / presentation low frequency students. The display 132 of the teacher terminal 13 operates as a presentation unit that visually presents information about correct answers / presentation low-frequency students extracted by the extraction unit to the teacher. The student information may be a student ID or a student ID and a student name.

<Third example>
In the third example shown in FIG. 9, steps S11 to S14 are the same as those in the second example shown in FIG. In the third example, the teacher 40 instructs the communication class server 10 to display the correct answer / presentation low frequency student answer extracted in step S13 anonymously on the classroom display 11 in step S21.

  Also in the third example, the teacher 40 may notify the communication class server 10 including not only the correct answerer but also the student who made an interesting mistake.

  In step S22, the CPU 101 of the communication class server 10 extracts the answer of the correct answer / presentation low frequency student from the still image data on the paper on which the answer transmitted from each student is written. In step S <b> 22, the image / sound processing unit 102 synthesizes still image data so that the correct answer / presentation low-frequency student's answer becomes a window 111, as shown in FIG. 10, and supplies it to the classroom display 11.

  As a result, the correct answer / presentation low-frequency student's answer is displayed on the classroom display 11. FIG. 10 shows an example in which there are six correct answer / presentation low frequency students. In FIG. 10, only an answer at the upper left end part is specifically shown as an example of an answer, and the remaining answers are omitted.

  Since the relay camera 12 is photographing the classroom display 11, the student can see the answer displayed in each window 111. Neither student ID nor name is displayed in each window 111. That is, the answer of the correct answer / presentation low frequency student is displayed anonymously. However, if his / her answer is displayed on the classroom display 11, it can be understood that the answer is his / her answer, and the student can recognize whether or not his / her answer was correct.

  The classroom display 11 operates as a notification unit that informs the student extracted by the extraction unit that extracts the correct answer / presentation low frequency student that his / her answer is correct. When all the students can see the answer by the correct answer / presentation low-frequency student like the classroom display 11, the notifying part should open the answer anonymously. Instead of notifying by the classroom display 11, the correct answer / presentation low frequency student may be notified individually that the answer is correct.

  In step S23, the teacher 40 operates the teacher terminal 13 to select one of the six correct / announced low-frequency students. In step S23, the communication unit 109 transmits notification information that prompts the selected student among the correct answer / presentation low-frequency students extracted by the extraction unit to present.

  Similarly, the notification information may be, for example, message data for calling “Would you like to announce it”, moving image and audio data, audio data, or a button displayed on the display 307. The students who have been encouraged to make presentations are students who have rarely announced in the past, but since they have already recognized that their answers are correct, they can lower the psychological hurdle to making a presentation.

  The student who is prompted to present accepts the presentation in step S24. For example, the student who is prompted to send the presentation may transmit any one of message data, moving image and voice data, and voice data that answer “I will give a presentation”. If the teacher 40 does not accept the presentation, the teacher 40 may select another student from the correct answer / presentation low frequency student and execute Step S23 again.

  In step S25, the teacher 40 transmits notification information that prompts the student who has accepted the presentation to start the presentation. The notification information may be, for example, message data calling for “Please announce”, moving picture and voice data, or voice data.

  In step S26, the student who has been prompted to make a presentation shoots himself / herself who announces the answer at the student terminal 30 and transmits the video and audio data to the communication class server 10 or collects only the audio. The voice data is transmitted to the communication class server 10. In step S27, the communication unit 109 of the communication lesson server 10 distributes the answer announcement video and voice data or voice data to the student terminal 30 and the teacher terminal 13 of students other than the student who presents the answer.

  Instead of distributing the video and audio data transmitted by the students to the student terminals 30 as they are, the following may be performed. The classroom display 11 displays a moving image of the moving image data of the student who announces the answer instead of the answer of the correct answer / announced low-frequency student. The video data of the student who announces the answer photographed by the relay camera 12 is distributed to each student terminal 30. In addition, the audio data transmitted by the student is distributed to each student terminal 30.

  In addition, after the announcement according to the first to third examples, the CPU 101 updates the announcement rate in the announcement rate table 106 automatically or in response to an operation by the teacher 40.

  As described above, according to the lesson system and lesson support method of this embodiment, even if there is no student who wants to announce the answer to the problem, the student can be prompted to announce the answer, and the lesson can be activated. it can.

  In particular, according to the third example described above, even if a student who has been prompted to make a presentation is a student who has hardly made a presentation in the past, the psychological hurdle to making a presentation can be lowered. Students who are not able to participate actively can participate in the class. Therefore, a lesson can be activated effectively.

  By the way, in this embodiment, although expressed as a teacher and a student, a teacher means the position taught and a student means the position taught from a teacher. Teachers include not only teachers with teacher licenses, but also lecturers for classes without teacher licenses.

  The present invention is not limited to the embodiment described above, and various modifications can be made without departing from the scope of the present invention. Although the communication system lesson system is taken as an example in the present embodiment, the present invention can also be used in a lesson in which a teacher and a student meet together in the classroom and each of the teacher and the student uses a terminal. The present invention is not limited to a communication lesson system.

  When configuring the lesson system of the present embodiment, the use of hardware and software (computer program) is arbitrary.
