[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a learning device that is particularly convenient for improving one's educational level by using the auditory sense and, if necessary, the visual sense using a text book or the like. be.

[Technical background of the invention and its problems]

In general, conventional devices of this type record questions, answer explanations, and correct answers on a magnetic tape, and then present the questions to the learner by running and playing them back on a magnetic recording/playback machine. By determining the question asked and selecting and closing a push button switch prepared in advance with the same number of items as the answer explanation, the student learns by comparing and judging the electrical signal generated by operating the switch with the electrical signal corresponding to the correct answer. It has the function of displaying the correct or incorrect answer to a question, and if the answer is correct, the number of marks on the scoring display section is added up, and if the answer is incorrect, the magnetic tape is rewound and the question is presented again.

However, it is necessary to set the scoring weight for each question individually, such as when the questions that are presented sequentially are not at the same level and are set with gradually increasing difficulty.
Because it is simply an additive evaluation of the same numerical value such as 1 point or 10 points, learners can only understand the difficulty level of the problem presented by steps such as text, and furthermore, there is a risk of falling into a mere point game. .

In addition, if you accidentally answer the question correctly without fully understanding the content, you will move on to the next question one after another, so you will be required to make judgments beyond your ability for increasingly difficult questions. This has the inconvenience of having to rewind and start over.

[Purpose of the invention]

The present invention provides a learning device that has multiple functions that ensure that learning is effective, such as assigning scoring weights to individual questions in accordance with their level of difficulty, and constantly assessing the learner's level of understanding to encourage repeated learning. This is what we provide.

[Summary of the invention]

The present invention provides a magnetic tape on which a question signal including a question and several answer explanations is recorded, a question number signal indicating a different identification number for each question, and a scoring value corresponding to the difficulty level of each question. , a memory device that stores in advance the correct answer number corresponding to each question and the specified question number to be re-presented in case of an incorrect answer as fixed data, and the necessary basic questions that are stored according to the answer state of the answerer and the problem level. The present invention is characterized by being equipped with a reaction instruction device and a processing circuit for causing the user to start over from scratch and giving a scoring evaluation according to the difficulty level of the problem.

Reference numerals 11 and 12 are bandpass filter circuits that pass through, remove, and separate the question number signal 8 and switching signal 7 recorded at different frequencies.

Signal shaping circuits 13 and 14 shape the waveforms of the problem number signal 8 and switching signal 7.

Reference numeral 15 denotes a decoder, which converts serially input 4-bit signals into serial and parallel signals.

A processing circuit 16 decodes the output signal of the decoder 15 and reads out the correct answer number data corresponding to the question number signal 8 stored in the nonvolatile semiconductor memory of the storage unit 17.

Reference numeral 18 denotes a comparison circuit which receives the correct answer number signal from the processing circuit 16 and the answer number signal which is operated by the answering section 19 and converted into an electrical signal, and which is stored in the holding circuit 20 which temporarily holds the signal form. A correct answer signal or an incorrect answer signal is output.

Reference numeral 21 denotes a control circuit that supplies actuation timing pulses to each of the decoder 15, processing circuit 16, and comparison circuit 18.

Reference numeral 22 denotes a reaction instructing device which issues various reaction instructions such as displaying question numbers, displaying correct/false judgments, and displaying scoring based on processed signals from the processing circuit 16. Reference numeral 23 denotes a magnetic tape control section which performs playback and rewind switching operations of the magnetic tape 1 based on signals from the decoder 15 and processing circuit 16.

Next, the operation of the above configuration will be explained based on the processing flow shown in FIG.

When the magnetic tape 1 is run and reproduced by the magnetic recording/reproducing machine 9, the speaker 10 signals the start of the problem by the notification signal 4 recorded on the track 2, and the problem and problem recorded in the problem signal 4 are announced. Several answers to this question are indicated.

When the question instruction is completed, a voice prompting the learner to respond is emitted by the instruction signal 6. At the same time, the switching signal 7 and the question number signal 8 recorded on the track 3 are sorted by band filter circuits 11 and 12, respectively, and the question number signal 8 that has passed through the filter circuit 11 is passed through the signal shaping circuit 13. The signal is waveform-shaped and input to the decoder 15 as a 4-bit serial binary code. If the signal states are now ゜゜1=)H゛, "0=L", then as the fifth problem, the signal states recorded in problem number signal 8 are ゜゜1=)H゛, "H".
゛, "゜L", ゜"H" are input to the sequential decoder 15 in this order. Simultaneously with the input of the question number signal 8, the control circuit 21
From then on, a 4-bit clock pulse synchronized with this is applied to the decoder 15, and the question number signal 8 is serial-to-parallel converted and input to the processing circuit 16. Also, magnetic tape 1
When the question number signal 8 is read by the running reproduction of the question number signal 8 and the question number is read by the processing circuit 16, the processing circuit 16
A magnetic tape stop signal is output from the magnetic tape controller 23, which drives the magnetic tape controller 23 to stop the magnetic tape 1. Next, the processing circuit 16 that has read the question number reads the correct answer number data corresponding to the question number from the address corresponding to the question number in the memory 17, and applies it to the comparison circuit 18 to answer the learner's answer. wait. Here, when the learner judges the presented question and performs an answer operation using the open/close switch of the answer section 19, the answer number signal converted into an electric signal is held in the holding circuit 20, and The answer number signal from the holding circuit 20 is applied to the comparison circuit 18. In this way, the comparison circuit 18 compares the correct answer number data from the processing circuit 16 and the answer number signal code from the holding circuit 20,
When they match, a correct answer signal is output, and when they differ, an incorrect answer signal is output and fed back to the processing circuit 16. If the learner's answer is now correct, the processing circuit 16 sends the reaction instruction device 22
A correct answer signal is applied to activate a correct answer display lamp (not shown), and the scoring value data stored at the address obtained by adding, for example, 100 to the question number is read out from the memory 17, and the reaction instruction device 22 is activated. This will be indicated by a marking indicator that does not contain any markings. Here, the scoring value to be stored in the memory device 17 can be arbitrarily set according to the difficulty level of each question, so the total score of all questions is set to 6"100゛, and within that value It is possible to allocate marks.In this way, when the learner's answer is correct, after displaying the marks,
A magnetic tape running signal is applied from the processing circuit 16 to the magnetic tape control unit 23 to put the magnetic tape 1 into a running and playing state again, and the process moves on to the next problem.

Furthermore, if the learner's answer is incorrect, an incorrect answer signal is output from the comparison circuit 18 and fed back to the processing circuit 16.

An incorrect answer signal is output from the processing circuit 16 to the reaction instructing device 22, which activates an incorrect answer display lamp (not shown), and also outputs data corresponding to other question numbers stored at an address that is 20 squares added to the question number. is read from the memory 17. At the same time, a rewinding signal outputted from the processing circuit 16 is applied to the magnetic tape control section 23, and a reproduction/rewinding operation of the magnetic tape 1 is started. Here, the address content that has been added by 20 hachi to the problem number specified above is the one that remembers the problem number of several previous questions so that you can start over from the basic problem again depending on the difficulty level of the presented problem. For example, if the presented problem is number 5 and the problem number signal 8 recorded on track 3 of magnetic tape 1 is in the signal form corresponding to "゜010r゛," the learner can solve the problem. If you answer incorrectly, the question number signal 8 for that question will be set to ゜“00” so that you can try again from the second basic question.
10°, and the contents of the address obtained by adding 200 addresses to the presented problem number ゜“010r” in the storage device 17 are stored as problem number data “゜001σ゛”. The question number data read out from the storage device 17 in this way is stored in the temporary processing circuit 16, and by rewinding the magnetic tape 1,
The question number signal 8 is reproduced and sequentially input to a decoder 15 via a filter circuit 11 and a signal shaping circuit 13.

Ru. Here, when the question number data read out from the storage device 17 by a coincidence circuit or the like matches the question number sequentially reproduced and decoded by reproduction and rewinding, a coincidence signal is output. The coincidence signal is a preparation signal for switching the reproduction/rewinding state of the magnetic tape 1 to the sequential reproduction state, and in the reproducing/rewinding state, the switching signal 7 which is rewound and reproduced after the question number signal 8 is transmitted to the filter circuit. 1
2. When applied to the processing circuit 16 via the signal shaping circuit 14, a control signal is generated which stops the playback and rewinding of the magnetic tape 1 and simultaneously switches to the playback state, by means of a logical product with the above-mentioned preparation signal, etc. , is applied to the magnetic tape control unit 23. Therefore, if you answer the fifth question incorrectly as described above and want to try again from the second question, by rewinding the playback,
By reproducing the second problem number signal 8 having a recording format corresponding to ゛゜0010゛ and comparing it with the problem number data read out from the storage device 17, a preparation signal for switching the magnetic tape running is outputted; When the magnetic tape 1 is rewound and the switching signal 7 corresponding to the second problem is reproduced, a control signal for switching the magnetic tape running is output to the magnetic tape control section 23, and the switching signal 7 corresponding to the second problem is outputted to the magnetic tape control section 23. Switched to playback state. In this way, the second basic problem will be presented again. [Effects of the Invention] As detailed above, the present invention runs and reproduces a magnetic tape recording a problem and some answers to the problem, and reproduces the problem particularly by hearing, and if necessary visually by using a text book or the like.
