Description

The present invention relates to a learning support device, a learning support method, and a learning support program, and in particular to a learning support device, method, and program for supporting the learning of the structure of the human body.

When learners are acquiring various study items, they can use electronic devices in addition to traditional books to efficiently understand the study subject and use them to acquire knowledge (see Patent Documents 1, 2, 3, 4, etc.). Furthermore, electronic devices can not only display the study items, but also ask questions and provide answers to confirm the acquisition of the study items. This improves the efficiency of learning acquisition. Also, unlike books, with electronic learning support devices, learners' understanding is improved through the images displayed.

For example, when learning about human anatomy and tissues, the target audience is medical students and the like, so the content and scope of the learning is highly specialized, complex, and wide-ranging. In the case of conventional electronic learning support devices, teaching materials were generally made up of almost entirely digitalized content from books on human anatomy and tissues. For example, even students of osteopathy, physical therapy, and the like, who have a limited range of study subjects and fields, use teaching materials aimed at medical students and the like, and are therefore required to uniformly study more than is necessary.

In addition, because the content of books was digitized as teaching materials, previous electronic learning support devices were not necessarily designed to contribute to improving comprehension. Specifically, although the illustrated tissues and organs and their corresponding names were shown, learners had to infer for themselves what was being referred to.

The present invention has been made in consideration of the above points, and provides a learning support device, a learning support method, and a learning support program that can simplify and display the key points of specialized content, and further make the display format of illustrated images easy for learners to understand, thereby enhancing the effectiveness of learning, as well as the method and program.

That is, an embodiment of the present invention is a learning support device that includes a display unit that displays an image, an operation unit that accepts operations from a learner, and a control unit that controls the display unit and the operation unit. The control unit includes a display control unit that enables a structural diagram of the human body and tissue names corresponding to the structural diagram to be displayed simultaneously on the display unit, a display adjustment unit that adjusts the display mode of the structural diagram and tissue names according to the learner's operation and displays them on the display unit, a question generation unit that generates questions for the learner to answer regarding either the structural diagram or the tissue names or both and displays them on the display unit, an answer acceptance unit that accepts answers to the questions from the learner from the operation unit, and a correctness determination unit that compares the answers to the questions with the correct answers to the questions to determine whether they are correct or incorrect.

Furthermore, the display control unit of the learning support device may be configured to superimpose the organizational name on the display portion of the structural diagram.

Furthermore, the display adjustment unit of the learning support device may change the display color of a specific part contained in the structural diagram when displaying the structural diagram, thereby displaying the specific part of the structural diagram in a distinguishable manner.

Furthermore, the control unit of the learning support device may be provided with a question and answer memory unit that stores questions, answers, and results of correct/incorrect judgment, and the question generation unit may generate questions based on the results of the correct/incorrect judgment.

Furthermore, the acceptance of an answer on the operation unit of the learning support device may be by selecting an answer option corresponding to a question displayed on the display unit, or by inputting text into the display unit.

Furthermore, the display control unit of the learning support device may be configured to display a structural diagram corresponding to an input organization name based on the input of the organization name into the operation unit.

Furthermore, the operation unit of the learning support device may be equipped with a microphone unit, and answers may be accepted in the operation unit by vocalization into the microphone unit.

Furthermore, the display control unit of the learning support device may be configured to display a structural diagram corresponding to the pronounced organization name based on the pronunciation of the organization name into the microphone unit.

Furthermore, in the learning support device, the structural diagram may be a structural diagram of the human body's skeleton and muscles, and the tissue names may be names of the human body's skeleton and muscles.

Furthermore, the display control unit of the learning support device may display the muscles of the human body in the structural diagram according to their depth from the epidermis of the human body.

According to the learning support device of the present invention, a display unit that displays images, an operation unit that accepts operations from a learner, and a control unit that controls the display unit and the operation unit, the control unit being equipped with a display control unit that enables a structural diagram of the human body and tissue names corresponding to the structural diagram to be displayed simultaneously on the display unit, a display adjustment unit that adjusts the display mode of the structural diagram and tissue names according to the learner's operation and displays them on the display unit, a question generation unit that generates questions for the learner to answer regarding either the structural diagram or the tissue names or both and displays them on the display unit, an answer acceptance unit that accepts answers to the questions from the learner from the operation unit, and a correctness judgment unit that compares the answers to the questions with the correct answers to the questions and judges whether they are correct or incorrect, thereby simplifying and displaying the main points of specialized content and making the display mode of the illustrated images easier for the learner to understand, thereby improving the learning effect.

The learning support device of the embodiment is a device for a learner to study a learning subject using an electronic device described below. The learning support device is a device that enhances the learner's comprehension by making full use of a wider variety of expressions than can be expressed in books, and also enables the learner to confirm and improve their mastery of the learning subject by repeatedly asking and answering questions. The learning support device of the embodiment is a device that is primarily intended for learning the structure, shape, movement, and names of the skeletal and muscular tissues of the human body. In particular, the content is not as extensive as that of a textbook or manual on human anatomy, and the learning load is reduced by specializing exclusively in the human skeleton and muscles, excluding blood vessels and lymphatic vessels.

The learning support device is therefore intended for training of physical therapists, caregivers, chiropractors and the like who work in clinical medicine, nursing care and rehabilitation, who do not require the same level of expertise as doctors and medical students, but who do require accurate knowledge within a certain range. Of course, it may also be used by novices such as medical students. Learners are those who are taking these training courses.

Figure 1 is a schematic diagram showing the configuration of a learning support device 1 of an embodiment. The learning support device 1 is a tablet terminal or smartphone used by a learner (user) U1, or a personal computer used by a learner (user) U2. The terminal device of each learner (user) may be an independent stand-alone device, or, as shown in the figure, the terminal device of each learner (user) may be connected to a network 3. In the embodiment, a server 9 is connected to the network 3. The server 9 accumulates data on updates to the learning content and distributes it from time to time. In addition, it is also possible to aggregate answers on the terminal device (learning support device 1) of each learner and manage the learning progress of the learners using each learning support device 1.

In the following description of the embodiment, the learning support device 1 will be described as a tablet terminal. The learning support device 1 has a display unit 4 that displays images. The display unit 4 is configured to double as an operation unit 5 that accepts operations from the learner. The learning support device 1 has a control unit 10 that controls the display unit 4 and the operation unit 5. The learning support device 1 also has a microphone unit 6 as the operation unit 5. When the learning support device 1 is a personal computer (PC), the operation unit 5 is a keyboard 7 and a mouse 8 as shown in Figure 1.

Figure 2 is a block diagram showing the configuration of the control unit 10 of the learning support device 1. The control unit 10 is made up of hardware such as a display unit 4 (also used as the operation unit 5), a microcomputer required for various operational control such as receiving signals from the microphone unit 6, executing calculations, storing, etc., and is equipped with a CPU 11, ROM 12, RAM 13, a storage unit 14, an I/O 15 (input/output interface), etc.

When each functional unit of the control unit 10 (computer) is realized by software, the control unit 10 is realized by executing the instructions of a program, which is software that realizes each function. The recording medium that stores this program can be a "non-transient tangible medium" such as a CD, DVD, semiconductor memory, or programmable logic circuit. In addition, this program may be supplied to the control unit 10 of the learning support device 1 via any transmission medium capable of transmitting the program (network 3 in FIG. 1, other communication networks, broadcast waves, etc.).

The memory unit 14 of the control unit 10 (computer) is a well-known storage device such as a HDD or SSD. The memory unit 14 may also be an external server 9 (see Figure 1). The memory unit 14 stores various data, information, questions, answers, correct/incorrect judgments, a learning support program, various data required to execute the program, etc. Furthermore, each functional unit that performs various calculations, arithmetic operations, etc. is a computing element such as a CPU 11. The display unit 4 (display device such as a display), microphone unit 6, etc. are connected to the I/O 15. Note that when the learning support device 1 is a personal computer (PC), the keyboard 7 and mouse 8, which serve as operation units, are connected to the I/O 15 (not shown).

The functional units in the CPU 11 of the control unit 10 are shown as the block diagram in Figure 2. Each functional unit includes a display control unit 110, a display adjustment unit 120, a question generation unit 130, an answer acceptance unit 140, a correct/incorrect determination unit 150, a question and answer storage unit 160, etc. The operation and execution of the CPU 11 of the control unit 10 is realized in software terms by a learning support program loaded into the main memory, etc.

The display control unit 110 controls the display unit 4 so that a structural diagram of the human body and the tissue names corresponding to the structural diagram can be displayed simultaneously.

The schematic diagram in Figure 3 is an example of a display of a structural diagram 500 of the human body on the display unit 4 of the learning support device 1, showing the skeleton of the right shoulder and upper arm of the human body. The display control unit 110 superimposes tissue names (skeleton names) on the portion where the structural diagram 500 is displayed, and displays the tissue names superimposed in the corresponding locations. In addition, reading kana (furigana) may be provided together with the tissue names. Although not shown in Figure 3, in the case of muscles, similarly, tissue names (muscle names) are superimposed on the portion where the structural diagram is displayed, and displays the tissue names superimposed in the corresponding locations. In addition, reading kana (furigana) may be provided together with the tissue names.

In the example of Figure 3, a structural diagram 500 of the skeleton of the right shoulder and upper arm of a human body is shown, and the name of the bone, such as the humerus (upper arm), is displayed at the position of the skeleton, along with the names of the tissues of the bone and the names of the tissues of the detailed parts. Similarly, the name of the bone, such as the humerus (upper arm), is displayed at the position of the skeleton, along with the names of the tissues of the detailed parts. In Figure 3, the names of the skeletal tissues 510, namely the greater tubercle, lesser tubercle, intertubercular groove, humerus, supraglenoid tubercle, and glenoid cavity of the scapula, are displayed superimposed on the position of the skeleton (the displayed part of the structural diagram). Of course, the display of the tissue names in Figure 3 is merely an example, and the amount of tissue names displayed can be increased or decreased depending on the learning content, etc.

The display adjustment unit 120 adjusts the display mode of the structural diagram and tissue names according to the learner's operation and displays them on the display unit 4 of the learning support device 1. In the structural diagram 500 of the display example in Figure 4, the human body skeleton and the muscles connected to the skeleton are displayed.

The learner can freely change the viewing angle of the image of the structure diagram and tissue names displayed on the display unit 4 so that it is easy to see, and can see the details in detail. Since the operation unit 5 itself is also used as the display unit 4, the display mode may be adjusted appropriately through operation icons (not shown) displayed on the display unit 4. In addition, in the case of a tablet terminal, a smartphone, etc., the screen may be directly touched to rotate and enlarge/reduce. First, in the schematic rear view of FIG. 4(A), the entire skeleton of the back side of the human body is displayed, along with two types of muscles connected to the skeleton. In the figure, the display focuses on the deltoid and latissimus dorsi. In this way, the structure of the entire skeleton on the back side and the muscles to be studied can be extracted and grasped in a wide area of the skeleton.

Next, in the rear perspective schematic diagram of Figure 4(B), by turning the right shoulder forward, the position of the deltoid and latissimus dorsi muscles to be studied is clearly displayed in a perspective view. In the enlarged rear perspective schematic diagram of Figure 4(C), the enlarged display makes it possible to grasp the connection points between muscles and the skeleton, and the detailed structure of the muscles and skeleton. In the side perspective schematic diagram of the right arm of Figure 4(D), it is possible to grasp the skeletal and muscular structure of the arm and chest on the side.

In addition, the schematic diagram of Figure 5 is also an example of display on the display unit 4 of the learning support device 1. In the front oblique schematic diagram of Figure 5(A), the sternum, ribs, etc. are mainly shown as the skeleton of the chest. The display of tissue names in the diagram is unclear and is for convenience. In the enlarged right side schematic diagram of Figure 5(B), the skeleton of the arm is further emphasized. In common with Figures 5(A) and (B), the names of bones (tissue names) are displayed superimposed on the bones (structural diagram) of each part. In the right side schematic diagram of Figure 5(C), the enlarged display of Figure 5(B) is released and the skeleton of the upper body is displayed. In addition, the display orientation can be rotated from the front to the side. In other words, the learning support device 1 can rotate the structural diagram of the skeleton and muscles in response to input from the learner, and display the skeleton and muscles from the desired orientation.

The left screen of the display unit 4 in Figure 5 is provided with a touch-type display selection operation button 400. Common to Figures 5 (A) to (C), from top to bottom, there are four figures (icons, instruction buttons) corresponding to "skeleton display", "muscle display", "rotation display", and "return display". The display adjustment unit 120 adjusts the display mode of the structural diagram and tissue names according to the learner's operation and displays them on the display unit 4 of the learning support device 1. The learner (user) can switch between the displays of Figures 5 (A), (B), and (C) by operating the display selection button. Also, in Figure 5 (C), multiple operation buttons 400 are provided below the display unit 4 for selecting the display angle, direction, etc.

In the display unit 4 of Figures 5 (A) and (B), an input area 410 for search terms is displayed as an operation unit in the upper right part of both figures. When the learner (user) inputs the desired organization name (character input, etc.) into the input area 410, the display adjustment unit 120 displays a structural diagram corresponding to the input organization name on the display unit 4. Then, a structural diagram (skeleton in the figure) corresponding to the organization name is displayed as shown in Figures 5 (A), (B), and (C). In other words, based on the input of the organization name into the input area 410 of the display unit 4 (which also serves as the operation unit 5), a structural diagram corresponding to the input organization name is displayed.

Figure 6 is a schematic diagram showing a specific area of a structural diagram displayed on the display unit in a distinguishable manner. Figure 6 (A) is a schematic diagram mainly showing a front oblique view of the right shoulder. For example, when a desired tissue name is input from the input section 410 of the display unit 4 in Figures 5 (A) and (B) described above, in addition to displaying the entire structural diagram and tissue name in Figure 4 or Figure 5 described above, as shown in Figure 6 (A), the display color of a specific part included in the structural diagram 500 is changed by the learner's operation through the display adjustment section 120 when displaying the structural diagram 500, and is displayed as a change display section 501. As a result, the specific area (change display section 501) in the structural diagram 500 is displayed in a distinguishable manner at a glance compared to other areas. The change display section 501 in Figure 6 (A) is a display of the area of the humeral head.

Figure 6 (B) is a schematic diagram in which the display unit 4 further displays operation buttons 400 and input area 410. In this figure, specifically, based on the operation of inputting an organization name using operation buttons 400 (operation unit 5 in display unit 4), a structural diagram corresponding to the input organization name is displayed. Then, a search function linked to input area 410 displays the structural diagram corresponding to the input organization name. For example, "humerus" is input into input area 410. Then, as shown in the figure, the color of the skeleton in the structural diagram corresponding to the humerus changes and flashes, and it is displayed together with the organization name to be searched for in the structural diagram so that it can be distinguished at a glance compared to other areas.

Instead of inputting characters into the input section 410, the learner (user) can speak (input voice) the name of the organization they wish to search for into the microphone unit 6 (see FIG. 1). Then, through voice recognition based on the pronunciation of the organization name into the microphone unit 6, a structural diagram (skeleton, muscles) corresponding to the pronounced organization name is displayed on the display unit 4. It is possible for the learner (user) to search for and display a structural diagram corresponding to the organization name by pronunciation as well, which improves convenience.

In a diagram of the human body structure, when it comes to muscles, multiple different types of muscles are layered on top of each other as one moves deeper from the body surface (skin) to the interior of the body. Therefore, when understanding muscles, it is necessary to understand not only the tissue names, but also their arrangement and structure, etc., taking into account their depth in the human body. However, beginners often have difficulty understanding muscles in three dimensions. Therefore, the learning support device 1 of the embodiment makes it possible to display muscles in stages so that the arrangement and layering can be easily understood in addition to the names of the muscles.

Figure 7 is an example of an operation screen for displaying the muscles of the human body in a structural diagram according to their depth from the epidermis. It is possible to display muscles corresponding to intermediate stages from "muscle attached" at one end to "bone only" at the other end. Specifically, by moving the round shape (icon, instruction button) in the diagram in a straight line, the display mode can be freely controlled, from a display with a lot of muscle (on the epidermis side) to a display with less muscle (on the inside side, closer to the bone).

Figure 8 is a schematic diagram of a structure diagram showing the increase and decrease of muscles. In the order of Figure 8 (A), (B), and (C), the muscles are gradually reduced and displayed from the epidermis side of the human body to the inner side of the human body (the side closer to the bone). It is also possible to display the muscles gradually overlapping by reversing the order of Figure 8 (A), (B), and (C). As can be seen from the muscle display shown in the figure, in addition to the tissue name of the muscle itself, it is possible to learn the shape, arrangement, and relationship of the muscle to the skeleton (how the muscle is attached) according to the depth in the human body from the epidermis to the skeleton. Although it is not clear in the figure, the corresponding tissue name (muscle name) is also displayed superimposed on each muscle. Also, as shown in Figure 8 (D), the orientation of the structure diagram of the human body can be freely changed to eliminate blind spots on the display.

Next, the question generation unit 130 generates questions for the learner to answer regarding either or both of the structural diagram and the organizational name, and displays the questions on the display unit 4. The answer acceptance unit 140 accepts answers to the questions from the learner from the operation unit 5 (display unit 4).

The correctness judgment unit 150 compares the answer to the question with the correct answer to the question to judge whether it is correct or not. The control unit 10 is also provided with a question and answer storage unit 160, which stores the question, the answer, and the result of the correctness judgment. The question generation unit 130 then generates a question based on the result of the correctness judgment. The display mode on the display unit 4 will now be explained using the schematic diagrams of Figures 9 to 11.

In the schematic diagram of FIG. 9(A), a question 425 is displayed on the operation unit 5 (display unit 4) to be answered by the learner regarding either the structural diagram or the organization name, or both. In addition, answer options 420 for accepting answers to the questions from the learner are displayed on the operation unit 5 (display unit 4). In the figure, four answer options 420 are shown.

The schematic diagram of Figure 9 (B) shows the stage where the learner (user) is answering. In the figure, when the learner (user) touches the answer option 420 displayed on the operation unit 5 (display unit 4) with his/her finger F, the display color of the selected answer option 420 changes, indicating that the answer option 420 has been selected and accepted as an answer. In this way, the learner's (user's) proficiency is improved by repeatedly selecting multiple questions for the learner to answer and answers to those questions.

The way of answering the questions can be written in addition to the format of the options in Fig. 9. In the schematic diagram in Fig. 10, the operation unit 5 (display unit 4) displays a question 425 for the learner to answer about either the structural diagram or the organization name or both, a selection button 431 for answering, and a written answer field 433.

In the example of FIG. 10, the learner (user) answers question 425 in writing, and therefore selects "Written" from answer format selection button 431. Then, as an answer to question 425, the learner writes with a fingertip, a touch pen, or the like in the written answer field 433 displayed on operation unit 5 (display unit 4).

In addition, when "voice" is selected from the answer format selection button 431, the learner (user) can pronounce (voice input, speak) the answer to the question 425 into the microphone unit 6 (see FIG. 1). In this case, the microphone unit 6 is the operation unit for accepting the answer.

Furthermore, as shown in the schematic diagram of FIG. 11(A), a question 425 consisting of a diagram of the structure of the human body (an example of a skeleton) and text is displayed on the operation unit 5 (display unit 4). Four answer options 420 are then displayed. In this way, the way questions are set and created is not limited to just words or just figures, as in typical book learning, but also takes into account images (videos), making it possible to set questions and answer questions that take into account both ease of understanding and improved learning effectiveness.

Next, after an answer is actually received from the learner (user) by selecting options, writing, or even by voice, the correctness determination unit 150 compares the question with the received answer and determines whether it is correct or not. It is possible to determine whether an answer is correct or not immediately after it is given, rather than simply leaving it as it is.

In an embodiment, as shown in FIG. 11 (B), if the answer option 420 selected by the learner (user) is correct, a "○" (circle) is displayed, making it clear whether the answer is correct or incorrect. If the answer is incorrect, an "×" (incorrect) display (not shown) is displayed. Of course, the learning support device 1 (tablet terminal) can be configured to emit a voice message indicating "correct" or "incorrect" from a speaker (not shown).

Figure 12 is a schematic diagram of a display showing the results of an analysis of the learner's (user's) level of understanding. In the example shown, a radar chart showing the accuracy (correctness rate) of answers for each item is displayed on the left side of the page, and an evaluation for each item is displayed on the right side of the page. By repeating questions and answers in each field, the learner (user) can objectively grasp his/her own level of understanding of the subject matter being studied (skeleton, muscles, their movements, functions, etc.), as well as weak areas.

The schematic diagrams of Figures 13 to 15 are example images used for learning about the origin and insertion of skeletal muscles. Here, the origin (origin of skeletal muscle) refers to the end of the skeletal muscle that is connected to the bone and is closer to the center of the body (proximal). And the insertion (insertion of skeletal muscle) refers to the end of the skeletal muscle that is connected to the bone and is farther from the center of the body (distal). In this way, when learning about skeletal muscles, it is necessary to comprehensively understand the position, arrangement, depth from the body surface, and connection method of the skeleton in the human body. In particular, since the origin and insertion of skeletal muscles are three-dimensional and complex, it is not easy to understand only from a book. Therefore, the learner (user) can deepen his/her understanding through moving images by moving the structural diagram 500 through the operation unit 5 (also used by the display unit 4) while looking at the structural diagram 500 displayed on the display unit 4 of the learning support device 1 of the embodiment.

Specifically, the learner (user) can select operation buttons 400 (operation unit 5 on display unit 4) shown in the schematic diagrams of Figures 13 and 14 to perform operations such as breaking down skeletons and muscles, enlarging and reducing, rotating, and repeating. The structural diagram 500 in Figure 13 is an example image showing the origins and insertions of skeletal muscles, mainly those in the chest, and is displayed with muscle display 516 related to skeleton display 515 added. Additionally, an explanation column 520 is displayed to the right of display unit 4, and the content to be currently learned, the names of skeletons related to their origins and insertions, functions, etc. are displayed in order in explanation column 520.

The schematic diagram in Figure 14 is an example of an enlarged view of the pectoralis major muscle and upper arm area in Figure 13. The rest of the function is displayed in the explanation column 520. By enlarging the view as in the schematic diagram in Figure 14, the shape of the subdivided muscles and their connection to the skeleton can be confirmed and understood more clearly.

The schematic diagram of FIG. 15 is a question 425 posed to the learner (user) after completing the study of origins and insertions of skeletal muscles in FIG. 13 and FIG. 14, etc. Four image options are displayed on the left side of the operation unit 5 (display unit 4), and four answer options 420 are displayed on the lower side of the operation unit 5 (display unit 4). In this way, the understanding of the correspondence between the illustration and the wording (terminology) is tested, and as a result, learning progresses efficiently. Of course, the schematic diagrams of FIG. 13 to FIG. 15 are only examples, and there are naturally other display modes of the skeletal and muscular parts of the human body other than those shown. In addition to the multiple-choice questions of the schematic diagram of FIG. 15, as mentioned above, answers may be written or even spoken (not shown).

In the learning support device 1 of the embodiment, not only can the device receive questions and their answers to assist learning, but it can also store questions, their answers, and the results of the correct answer judgment through the question and answer storage unit 160. Based on the results of the correct answer judgment for each answer, the question generation unit 130 generates and asks questions focusing on areas with a low correct answer rate. The learning support device 1 incorporates a so-called adaptive learning method. There is variation in areas and items that are strong and weak for each learner (user). Therefore, in order to respond to individual learners (users), it is necessary to repeatedly ask different questions to each learner (user). In this way, it is possible to obtain a certain level of learning content in a specified period of time while responding to the individuality and characteristics of the learner (user).

In addition, the question and answer storage unit 160 can use machine learning on the questions, their answers, and the results of the correct/incorrect judgment to estimate the answering tendencies, weak areas, and items of each individual learner (user). For example, suppose that a certain learner (user) has a high rate of correct answers to questions about muscle names, but a low rate of correct answers to questions about muscle movements. In this case, the learner (user) is good at understanding tissue names, but is poor at understanding muscle movements. It can then be estimated that he or she is probably also poor at understanding skeletal movements. Therefore, the number of questions about muscle and skeletal movements is increased from the normal question settings.

For example, when estimating the correct answer rate for questions in areas of strength and areas of weakness (relative comparison with areas of strength), machine learning techniques such as support vector machine (SVM), model tree, decision tree, neural network, multiple linear regression, locally weighted regression, and probabilistic search method are used. Of course, the analysis techniques are not limited to those listed and may be used as appropriate.

Now, using the flowcharts of FIG. 16 and FIG. 17, the learning support method and the learning support program in the learning support device 1 of the embodiment will be described. The learning support method is executed by the CPU 11 of the control unit 10 based on the learning support program. The learning support program causes the control unit 10 (a so-called computer) in FIG. 1 to execute various functions such as a display control function, a display adjustment function, a question generation function, an answer acceptance function, a correct/incorrect judgment function, and the like. Furthermore, the learning support program causes the control unit 10 (a so-called computer) in FIG. 1 to execute various functions such as a display control function, a display adjustment function, a question generation function, an answer acceptance function, a correct/incorrect judgment function, and a question and answer storage function. Note that each function overlaps with the description of the learning support device 1 described above, so details will be omitted. Of course, each function can be operated independently. For example, it is also acceptable to omit the questions and their answers and simply view a diagram of the human body structure.

Of course, various steps necessary for the operation of the control unit 10 itself are also included.

The display control function allows the structure diagram of the human body and the tissue names corresponding to the structure diagram to be displayed simultaneously on the display unit 4 (S110; display control step). The display adjustment function adjusts the display mode of the structure diagram and the tissue names by the learner's operation and displays them on the display unit 4 (S120; display adjustment step). The question generation function generates questions for the learner to answer regarding either the structure diagram or the tissue names or both, and displays them on the display unit 4 (S130; question generation step). The answer acceptance function accepts answers to questions from the learner from the operation unit 5 (S140; answer acceptance step). The correctness judgment function compares the answer to the question with the correct answer to the question and judges whether it is correct or not (S150; correctness judgment step). Each of the listed functions is executed by the CPU 11 of the control unit 10. The correctness judgment function also includes a display (notification) step for displaying (notifying) the result of the correctness judgment, such as displaying the correct answer as shown in FIG. 11 (B) above, or displaying the incorrect answer, displaying the correct answer, and pronouncing the correct answer by voice.

In the processing of the control unit 10 in the flowchart of Figure 17, the various steps of the display control step (S110), display adjustment step (S120), question generation step (S130), answer acceptance step (S140), and correct/incorrect determination step (S150) are common to all of the above, and further include a question and answer recording step (S160). The question and answer recording function stores the question, the answer, and the result of the correct/incorrect determination (S160; question and answer recording step). The question and answer recording function is also executed by the CPU 11 of the control unit 10.

The computer program of the present invention described above may be recorded on a processor-readable recording medium, and the recording medium may be a "non-transitory tangible medium" such as a tape, disk, card, semiconductor memory, programmable logic circuit, etc.
