Description

  It belongs to the field of devices that send and receive interactively teaching contents, information, test questions, answers to test questions, corrections and advice on answers, etc. using communication methods that do not use cables such as wireless or infrared.

  There is a method to measure the degree of understanding of a student by giving a verbal unilateral message to a student when a teacher or teacher in a classroom, for example, in a classroom, and then examining the content taught at a later date. It was taken. In this method, even if you want to ask a question, you often hesitate to raise your hand, or you are not confident to explain the question verbally, and as a result, you end up without asking. In recent years, a method has been adopted in which a personal computer is connected to the Internet or the like by wire connection, the teaching contents are transmitted to the student via the personal computer, a test is performed, and the answer is collected.

  In the conventional technology described here, it is common to check the attendance by making a call to grasp the attendees of the class being conducted. However, it takes time to make a call, especially when the number of students is large, resulting in wasted important class time.

An antenna connected to the host computer is disposed above the entrance of the classroom. This antenna is used as a means for issuing information from a host computer, for example, notification of health checkups, athletic meet, etc., or for transmitting information between teachers and students and information between students. In particular, in the information transmission between the teacher and the student, the ID information that is the destination of the information is included in the transmission signal, so that only the information addressed to itself can be collected (see Patent Document 1).
JP-A-10-282873 (pages 6-8 and 4-10)

However, unilaterally speaking the teaching content is difficult for the teaching side to understand how far the students have understood, and as a result, it may become a factor that produces students who are unable to follow the class, As a result, it is necessary to take supplementary training at an additional educational institution, etc. Further, in a multi-function device such as a personal computer, it is necessary to study first by moving the device, and it is necessary to devote time to contents that are not related to the subject learning that is the original purpose. In addition, multifunctional devices are multi-functional, so students are bored and are interested in functions and software that are not related to the class, and they play with functions and software that are not related to the original class during the class. Will end up. As an example, playing a computer game during a class or searching for a site of interest on the Internet spends time, and as a result, the multi-function device returns and interferes with the class. Of course, it is possible to delete unnecessary functions and software, but it is uneconomical to delete the functions of the multifunctional device.

  Therefore, it is desired that the device is a simple device that satisfies only the target function from the beginning. In addition, in the case of a personal computer fixed on a wired connection network, personal information of a person used later by a person who will be used later, such as test results and results, etc., unless the person used is always the same person. It will be the result that you can know. Therefore, a learning device composed of a communication device and a function that eliminates incidental functions and displays only information for which the functions are intended, inputs information, and inputs and outputs voices is required.

  In addition, a host computer is required, and if this is introduced into all classrooms, the system becomes large. Therefore, such a device cannot be easily installed only in one classroom or in a limited room.

  The learning apparatus according to the present invention includes an antenna, a two-way radio that transmits and receives information to the learner, a display device that displays the information sent from the learner or input by the learner, and processes the information A central processing unit; an input device for input by the student; and a storage device for storing the information from the learner and the information sent by the student to the learner.

  The learning device of the present invention includes an antenna, a two-way radio that transmits and receives information to a student, a display device that displays the information sent from the student or input by a student, and processing the information. A central processing unit to perform, an input device for input by the learner, and a storage device for storing the information from the learner and the information sent by the learner to the learner.

  In the learning device of the present invention, the display device has a plurality of display devices in order to display information sent from a plurality of students.

  In the learning apparatus of the present invention, the bidirectional radio transmits and receives information by a single hop method or a multi-hop method.

  It may feel embarrassing for the students to raise their hands and ask the teacher about the contents of the lesson that cannot be understood during the class. As a result, the class ends without understanding the contents of the class, and there is a possibility that problems such as not being able to get good points in the exam may occur. The present invention makes it possible to send information to the instructor that he / she does not understand in such a way that other students who are present cannot understand even with such a psychology, and to draw out a response to it. Therefore, even if the lesson is conducted for a plurality of students, the effect of individually teaching and the effect of increasing the understanding of the class can be obtained.

  The wireless network system implemented in the present invention uses a single-hop system, so-called direct communication system and multi-hop system, so-called repeater function between wireless devices, to deliver information to a desired wireless device via a plurality of wireless devices. There is a method. Since the infrared communication function is the same as that of the wireless single-hop method, the infrared communication will be described in the wireless single-hop method.

  In the present embodiment, a learning apparatus using a single hop method will be described. In the learning device of the present invention, FIG. 1 is an external view of a learning device possessed by a student, that is, a person taking a class, and FIG. 3 is a block diagram of the learning device possessed by the student. The student's learning device 100 displays information sent from the person (lecturer) who performs the lesson or information input by the student.

  The student learning device 100 displays the antenna 110, the two-way wireless device 120 that transmits and receives information to the learner learning device 200, and displays information from the learner to the learner and information that the learner wants to send to the learner. A display device 130 for displaying, a central processing device 140 for processing various information, an input device 150 for input by a student, and a storage device for storing information from a learner and information sent by a student to a learner 160 and an apparatus power supply 170 for supplying power to the learning apparatus 100.

  The display device 130 uses, for example, a liquid crystal panel or a light emitting diode panel. The input device used when the student inputs is, for example, a touch panel, a keyboard, a mouse device, or the like. The two-way radio 120 is a communication device that performs non-cable communication. For example, a wireless device or an infrared communication device. The apparatus power source 170 is, for example, a rechargeable battery or a battery. In this embodiment, the same frequency of the weak wireless standard, for example, a wireless device of 315 MHz bidirectional communication is used as the communication device. Each student learning device 100 has an individual recognition code.

  Next, the learning device on the lesson side will be described. FIG. 2 is an external view of the learning device used by the learner, and FIG. 4 is a block diagram of the learning device used by the learner. The learner's learning device 200 displays information sent from the learner and information input by the learner. The learner's learning device 200 includes an antenna 210, a two-way radio 220 that transmits / receives information to / from the learner's learning device 100, and a display device 230 that displays information sent from the learner and information input by the learner. A central processing unit 240 for processing information, an input device 250 used when a student inputs, a storage device 260 for storing information from the student and information sent by the student to the student, and a learning device The apparatus power supply 270 supplies power to the apparatus 200.

  The bidirectional wireless device 220 is a communication device that performs non-cable communication, for example, a wireless device or an infrared communication device. The display device 230 is, for example, a liquid crystal panel or a light emitting diode panel. The learner's learning apparatus 200 has display screens 230a, 230b,..., 230n that display the states of a plurality of students. The learning device 200 used by the student is different from the learning device 100 used by the student, and can display information of a plurality of students. In this embodiment, student information is displayed using individual panels. However, a method of displaying information of a plurality of students with a partition on one panel is also possible. The input device 250 is, for example, a keyboard or a mouse device. The device power supply 270 is, for example, a rechargeable dry battery or a battery.

Note that the communication device 220 associated with the learner's learning device 200 has the same frequency and standard as the communication device 120 included in the learner's learning device 100, and similarly has a unique recognition code.
Next, the operation of the present invention will be described based on a flowchart. FIG. 5 is a flowchart relating to class progress. The educational site where the present invention is implemented is a cram school for several children. In the cram school classroom, cram students are randomly seated. In this embodiment, an actual lesson flow will be described. First, both the student and the classifier turn on the learning devices 100 and 200 (step 100). First, it is confirmed whether or not the learning device 100 of the student on the device is operating normally and the attendance of the student is confirmed. The learner's learning device 100 calls the student's recognition code stored in the learning device 100 (step 101), emits radio waves (step 102), and receives the designated student's recognition code from the learning device. It is confirmed whether there is a response (step 103). The student's identification code that received the response is received (step 104), and the student's identification code is displayed on the designated part on the display device 230 of the learner's learning device 200. (Step 105). In this embodiment, the liquid crystal panel was turned on. The next student is selected (step 106). The operation confirmation and attendance confirmation of the learning device 100 of the student on the device 200 are performed up to the last student (step 107). After the operation confirmation and attendance confirmation of the learning apparatus 100 on the apparatus 200 up to the last student are completed, the classifier verbally re-calls only the absent student while watching the lighting state of the liquid crystal panel 230. (Step 108). Next, the learner's learning apparatus 200 sends the contents describing the lecture contents and the main points to the attending student's learning apparatus 100 (step 109). The instructor advances the lecture according to the contents of the lecture sent to the student (step 110). The student listens to the lecture (step 111). If the student cannot understand the content of the lecture (step 112), the student sends a notification that the lecture cannot be understood from the learner's learning device 100 to the learner's learning device 200 (step 113). As a specific method of sending the notification, the student simply clicks on the lecture content that is sent or sends the question content from the input device 150. The instructor receives a notification that the lecture cannot be understood (step 114). The instructor who has received the report gives an explanation again according to the lecture content or the question content indicated in the report (step 115). Next, it is confirmed whether it is within class time (step 116). If the lesson time has passed, the lecture ends (step 117).

  Since the contents written to the learning apparatus, the transmitted contents, and the received contents can be stored as a supplementary function of the learning apparatus, the student can substitute comments and understood contents for the learning apparatus instead of writing notes.

Next, the implementation of the test to measure the level of understanding of the lesson content at the end of the lesson will be explained. FIG. 6 is a flowchart for confirming the level of understanding of the student. This test has the purpose of grasping the level of understanding of the students, so the classifier has the purpose of improving the level of understanding and correcting mistakes by sending advice in the middle of the test by looking at the response status of the students. First, the contents of the exam are sent simultaneously from the learner's learning device 200 to the learner's learning device 100 (step 150). When the examination starts (step 151), the instructor's learning device 200 sends an instruction to each attending student's learning device 100 to give an answer to the test question (step 152). Then, the learning device 100 of each student sends back the answer inputted by the student to the learning device 200 of the learner (Step 153). The learner's learning device 200 displays the sent reply information of the student (step 154). The next student is selected (step 155). The above operation is performed for all students (step 156). Once the answer information of all the students is displayed, the instructor examines the answer information for each student (step 157). As a result of examination, if it is determined that information such as advice or indication to the student is necessary (step 158), information such as advice is sent to the learning device 100 of the student (step 159). The learning device 100 of the student receives the information such as the advice (step 160), and displays the information such as the advice on the learning device 100 of the student (step 161). The next student is selected (step 162). Examining the response information and sending information such as advice to all students (step 163). When the work of sending advice is finished, a certain period of time is waited (step 164). Until the test time is over (step 165), the process returns to the collection of answer information and the same operation is repeated. At the end of the test time, the learner's learning device 200 reads all the test responses of the students (step 166), and the learner takes it back and scores it until the next lesson (step 167). To the designated student (step 158)
By taking such a method, the privacy of each student can be protected and the comprehension ability for the class can be increased.

  In the first embodiment, the communication method in which the learner's learning device 200 communicates directly with the learner's learning device 100, that is, the single-hop method has been described. However, the number of students is large and the classroom is wide. In such a case, there may be a case where communication is not possible with a wireless device of a weak wireless standard. Here, if a radio device with a large high-frequency output such as a radio device with a specific power saving standard is used, radio waves propagate to an unexpected area, causing problems such as leakage of student-specific information and interference with other classrooms. . In the present embodiment, a wireless device having a function of receiving, temporarily storing and retransmitting information between the learner's learning device 100 and the learner's learning device 200, that is, an echo repeater, or an echo A method for connecting information by constructing a wireless network between repeaters, that is, a multi-hop communication method will be described. Since the actual lesson flow is the same as the contents of the above embodiment, in this embodiment, only a method for transferring information through one or a plurality of echo repeaters will be described.

  The hardware part of a wireless device having an echo repeater function is usually called a node. Communication via an echo repeater takes time for communication because it performs information reception, storage, and retransmission. Therefore, if the number of nodes is increased, the communication speed is greatly reduced, and actual communication is hindered. Therefore, in this embodiment, the number of nodes is one.

  FIG. 7 shows a flowchart of the multi-hop transmission method. First, the nodes 300a, 300b, 300c, and 300d are placed in the normal reception state (step 200). The learner's learning device 200 according to the first embodiment starts transmitting commands and information (step 201). The nodes 300a, 300b, 300c, and 300d receive the signal (step 202), demodulate (step 203), and store the contents in the storage device (step 204). When the learner's learning device 200 completes the transmission (step 205), the nodes 300a, 300b, 300c, and 300d add the information held by the nodes 300a, 300b, 300c, and 300d to the information stored in the storage device. High-frequency modulation is performed (step 206) and transmitted to the learning device 100 of the student (step 207). The student's learning device 100 receives information from the nodes 300a, 300b, 300c, and 300d (step 208). The feature of this mechanism is that the learner's learning devices 100a, 100b, 100c, 100d, 100e, 100f, 100g, and 100h know which node 300a, 300b, 300c, and 300d the information has been transferred to. It is. The student learning devices 100a, 100b, 100c, 100d, 100e, 100f, 100g, and 100h perform processing according to the contents of the information (step 209). As a result of the processing, when there is information that the student learning devices 100a, 100b, 100c, 100d, 100e, 100f, 100g, and 100h return to the learner learning device 200, the student learning devices 100a, 100b, and 100c are returned. , 100d, 100e, 100f, 100g, and 100h transmit the information to the node (step 210). The nodes 300a, 300b, 300c, and 300d receive the information (step 211), demodulate the received signal (step 212), and store it in the storage device (step 213). When the learning devices 100a, 100b, 100c, 100d, 100e, 100f, 100g, and 100h of the students finish the transmission, the nodes 300a, 300b, 300c, and 300d transfer the information stored in the storage devices to the nodes 300a, 300b, 300c, and 300c, respectively. The information held in 300d is added and subjected to high frequency modulation (step 214), and retransmitted to the learner's learning device (step 215). The learner's learning device receives information from the nodes 300a, 300b, 300c, and 300d (step 216). The same nodes 300a, 300b, 300c, and 300d are used as nodes through which information is sent and received.

  The case of passing through a plurality of nodes 300a, 300b, 300c, and 300d is the same as in the case of one node. Each node 300a, 300b, 300c, 300d sends information to the destination while receiving, demodulating, storing, and retransmitting the information. FIG. 8 shows a communication path of the communication between the student and the teacher by multi-hop. This figure shows a method in which a student and a lesson communicate with each other via four communication nodes 300a, 300b, 300c, and 300d.
