[0015]

[Table 1]

[0016]

[Table 2]

In Tables 1 and 2 above, the difficulty levels shown on the left side represent the difficulty levels of the word pairs shown on the right side, and the word pairs of each difficulty level are as follows. (A) Difficulty level 1: A combination of words in which the beginning of a word starts with R or L and continues to be a vowel. (B) Difficulty level 2: A combination of words in which R or L exists in the middle of a word and is subsequently a consonant. (C) Difficulty level 3: A combination of words in which R or L exists at the end of the word and the vowel immediately before it is a vowel. (D) Difficulty level 4: A combination of words in which R or L exists in the middle of a word and vowels are before and after the word. (E) Difficulty level 5: The beginning of a word starts with a consonant and continues, then R
Or a combination of words that is L. Here, natural numbers 1 to 5 indicating difficulty levels are assigned in ascending order from the smallest difficulty level to the largest difficulty level in listening to R and L.

Further, Table 3 is an example of a learning word selection classification table prepared for each learning level using word pairs classified by difficulty level, and by finely defining this classification, the learning word selection classification table can be obtained. It becomes possible to proceed with learning.
Although FIG. 2 is a graph of the word appearance rate in Table 3, the numerical values in FIG. 2 and Table 3 are used for different learning systems and are not matched. The contents of Table 3 and FIG. 2 used in this embodiment are stored in a rank-based question number table 22 described later.

[Table 3] ─────────────────────────────────── Rank Word Logarithm Word Occurrence Rate Speaker Count Difficulty 1 Difficulty 2 Difficulty 3 Difficulty 4 Difficulty 5 ──────────────────────────────────── 1 10 100% 0% 0% 0% 0% 1 2 10 80% 10% 0% 0% 0% 1 3 20 80% 10% 10% 0% 0% 2 4 20 70% 20% 10% 0% 0% 3 5 20 60% 20% 20% 0% 0% 3 :: :: :: :: :: :: :: :: :: :: N-1 30 40% 10% 10% 20% 20% 4 N 30 30% 10% 10% 20% 30% 5 ────────────────────────────────────

In Table 3, "rank" indicates that the overall learning level is, for example, about a plurality of N listening ability ranks (hereinafter referred to as "the rank") in order to be able to finely correspond to various listening ability of the learner. It is divided into ranks.). Here, the ranks are in ascending order from the one with the lowest ability to the one with the highest ability, and a natural number indicating the rank of the ability is attached. The "word logarithm" represents the minimum number of word pairs selected from the word sound source group and used in learning within the same rank. Here, the logarithm of the word is increased as the rank becomes higher. The “word appearance rate” is a predetermined appearance rate of words to be presented at one time of learning for each rank, which represents the degree of difficulty of learning, corresponding to each rank. Here, the word appearance rate of the difficulty level 1 is set to 30% for the rank N, decreasing from 100% for the rank 1 in order as the rank increases. On the other hand, the word appearance rate of difficulty level 5 is set to 30% for rank N, increasing from 0% for rank 1 in order as the rank increases. The word appearance rate for other difficulty levels is 0% for rank 1 as the rank increases.
It is increased or changed in order from. Where Table 3,
In FIG. 2 and the question number table 22 by rank, word pairs of low difficulty are added to a high rank at a certain ratio in order to give a learner a stimulus for continued learning. "Number of speakers" represents the number of speakers of a word used in one learning, and when trained by a specific speaker, it may fall into a discrimination method adapted to the characteristic peculiar to that speaker, Sound sources for multiple speakers are available. Here, the number of speakers increases as the rank increases. That is, the learners who listen to the word pairs uttered by more speakers are the higher ranks.

The learning system used in this embodiment is
As shown in FIG. 1, an MPU (micro processing unit) 10 such as a microcomputer, a CRT display 11, a keyboard 12, a mouse 13, and a voice synthesizer 14 are provided as hardware devices excluding a storage device. , These MPU10, CRT display 11,
The keyboard 12, mouse 13, and voice synthesizer 14 are connected via a bus. A speaker 15 is connected to the voice synthesizer 14.

The MPU 10 is, for example, a central processing control device such as a microcomputer, which executes a control for executing each process of the learning system, and a CP.
A control program executed by the U and a ROM in which data for executing the control program are stored in advance, and a RAM used as a work area of the CPU. Further, the CRT display 11 displays the question and the correct answer in response to the instruction signal from the MPU 10. In addition, keyboard 1
2 inputs the learner's information in the learner registration process,
It is provided to enter the answer result to the question,
The input data is output to the MPU 10 via the bus. The mouse 13 is used as a part of the keyboard 12 instead of the keyboard 12, and is provided for inputting the answer result to the question.

The voice synthesizer 14 responds to a predetermined instruction signal from the MPU 10 and a digital data signal of a uttered voice read from a speaker sound source file 50, which will be described later, in response to the English word which is a question of the learning system. An uttered voice is generated in the form of an electric signal and is output to the speaker 15 to utter. Similarly, the voice synthesizer 14 generates a chime sound in the form of an electric signal at the time of a correct answer to the question and outputs it to the speaker 15 to speak, and at the same time outputs a chime sound at the correct answer to the question. It is generated in the form of a signal and is output to the speaker 15 to speak.

Further, the bus connected to the MPU 10 is connected to at least one storage device which is composed of, for example, a hard disk magnetic storage device and which stores the following various file data and table data. Hereinafter, in this embodiment, the file and the table indicate the digital data stored in the storage device. (A) Word table 20, (b) Difficulty-level initial value index table 21, (c) Rank-based question number table 2
2, (d) learner management file 30, (e) individual learning history file 31, (f) speaker sound source file 50. Here, the individual learning history file 31 includes the following tables. (A) Difficulty index table 41,
(B) Word information table 42, (c) Previous question question table 43.

In the word table 20, as shown in FIG. 7, a word pair number and a difficulty level are attached to each of a plurality of word pairs which are questions to be asked. In the present embodiment, digital data of voiced voices of two words of each of the plurality of word pairs of ten speakers (shown as speakers 1 to 10) is stored in the speaker sound source file 50 in advance. As shown in FIG. 7, the word table 20 includes index data in the speaker sound source file 50 for each word pair, for example, labeled as A-1 and C-8. As shown in FIG. 8, the difficulty level-based initial value index table 21 is used when one learner first learns using the learning system and the number of word pairs for each difficulty and the word pair. Including the data of the number. In the example of FIG. 8, two word pairs are assigned to each difficulty level. That is, an equal number of word pairs are assigned to each difficulty level.

As described with reference to FIG. 2 and Table 3, the number-of-questions-for-ranks table 22 is 1 for each rank.
Total number of learning problems, number of problems of each difficulty, number of word pairs to be asked from the previous problem for one learner, number of word pairs in one pair, and speaker Number is assigned. In this embodiment, 10 problems are prepared for each learning and 10 problems are prepared for each rank. In addition, in selecting the word-to-speech for each difficulty level in each rank, the selection ratio is set in advance, and by combining the word pairs of the low difficulty class appropriately in the high difficulty rank, the learning continuity is maintained. I am devising so.

The "one-sided question" will be described below. For example, “RACE-LAC of difficulty 1 in Table 1
For the word pair “E”, the first question is to ask the word “RACE” to ask which word of the word pair, and the word “LACE” to say which word of the word pair. There are two questions with a second question that asks whether or not, that is, there are two questions for one word pair, and both questions in a learning are both questions. It is called a pair question. On the other hand, to give only one of these two questions in one learning is called one pair question. On the other hand, it is referred to as both-pair questions that both a speech that produces a voice of a word containing L and a dialogue that produces a voice of a word containing R are included in one word pair.

The learner management file 30 is a file for data relating to at least one learner who uses the learning system, and includes information such as the following data for one learner. (A) learner's name, (b) learner serial number which is a registration number, (c) ID number which is a personal identification number, (d) rank at the time of entrance examination, (e) current rank.

As the individual learning history file 31, one file is prepared for each learner, and one of the files is stored in the index table 41 for each learner as the difficulty level as described above. , The word information table 42,
It includes the previous question question table 43. The index address of each learner in the individual learning history file 31 is stored in the learner file 30.

The difficulty level index table 41 is, as shown in FIG. 10, for example, a current difficulty level index table changed by one learner learning from the difficulty level initial value index table 21. Similarly to the difficulty level-based initial value index table 21, the data includes the number of word pairs and the number of the word pair for each difficulty level. In the example of FIG. 10, for the learner, for example, the word pair of the word pair number 2 is changed from the difficulty level 1 to the difficulty level 2 as compared with the learning start time indicated by the difficulty level-based initial value index table 21. , The word pair of word pair number 3 has been changed from difficulty level 2 to difficulty level 3. That is, the learner finds that the problem of the word pair of the word pair numbers 2 and 3 is more difficult than the general learner. The word information table 42 is, for example, as shown in FIG.
As shown in 1 (a), the number of questions (ie, the number of repetitions of the problem) for each word pair of each word pair number in the repeated learning from the start of learning by the learner, the number of incorrect answers, And the number of correct answers. Further, the previous question question table 43 is, for example, as shown in FIG.
For each of the 10 question questions, the word pair number, the spelling of the word containing the R of the word pair number, the spelling of the word containing the other L, the correct classification, and the sound source data are included. Here, in the correct answer classification, a word including R is a correct answer or L
Indicates whether the step is correct. The sound source is shown in FIG.
The index data in the speaker sound source file 50 for each word pair shown in the word table 20 and the sound source data corresponding to the correct classification among them are shown. For example, in A-1 (R) of FIG. 12, the speaker is the speaker 1, R
Source file 50 for "RACE", which is a word containing
The sound source data above is shown.

Further, the speaker sound source file 50 is stored in the word table 20 shown in FIG. 7 and is, for example, A-1, C-.
Speaker sound source file 50 for each word pair, labeled 8
Includes digital data of vocalized speech for each two words of word pairs of ten speakers, corresponding to the index data above.

FIG. 3 is a flow chart of the main routine executed in the learning system of FIG. As shown in FIG. 3, first, in step S1, a question is displayed on the CRT display 11 as to whether the learner who is operating this learning is the first learning, and the relevant learner is the first learning. And keyboard 12 or mouse 1
When answering using 3 (YES in step S1)
On the other hand, if it is not the first time (NO in step S1), the process proceeds to step S5.

In step S2, a learner registration process is executed. In the process, the learner inputs the following data using the keyboard 12 in response to the question displayed on the CRT display 11. (A) Learner's name, (b) ID number which is a personal identification number.
In response to this, the MPU 10
A learner serial number, which is a registration number, is automatically given, the serial number and the input data are stored in the learner management file 30, and an individual learning history file 31 for the learner is created. In the latter process, a predetermined storage area is secured in the storage device for the individual learning history file 31, and the initial value data is stored. Specifically, the difficulty level-based index table 41 is shown in FIG.
The data of the initial value index table 21 for each difficulty level of 0 is stored as it is, and all the data of 0 is stored in the word information table 42 and the previous question question table 43.

Next, in step S3, the entrance examination process is executed, a predetermined number of questions for the entrance examination are similarly given in the learning process described later, and the learner who is the operator answers and the correct answer is given. Calculate the rate. And step S
In 4, the appropriate rank to be started by the learner is automatically determined based on the correct answer rate in step S3 according to a predetermined algorithm, and the information data is stored in the learner management file 30.

Further, in step S5, a question is displayed on the CRT display 11 as to whether or not the learning currently being performed by the learner who is operating is to be finished, and when the learner finishes, the keyboard is displayed. 12 or when using the mouse 13 to answer (step S
(YES in step 5), in step S10, the content of the individual learning history file 31 is updated and saved based on the result of this learning, and then the control process ends. As a result, the individual records are kept, and the learning can be started from the continuation of the previous time when the next learning is started. On the other hand, step S5
When it is answered that the process is not completed (NO in step S5), the process proceeds to step S6.

4 is executed in step S6, then the learning process of FIG. 5 is executed in step S7, and the difficulty level changing process of FIG. 6 is executed in step S8. In the difficulty level changing process, the rank is changed according to the learning result in the learning process. Furthermore, a review process is executed in step S9. In the review process, learning is performed by performing review including processes similar to steps S23 to S31 in the learning process described later in detail until the result of the learning in the learning process becomes a correct answer for the word pair problem that is incorrect. More effective. The learner gradually improves the listening and listening ability of English words L and R by repeatedly performing the learning in step S7 and the review in step S9. Further, after the review process, the process returns to step S5.

FIG. 4 is a flowchart of the learning problem creating process (step S6) which is the subroutine of FIG.
Here, an example of the process of the learning problem creation process will be described with reference to FIGS. 4 and 13 and 14.
13 and 14 are question question tables stored on the RAM in the MPU 10 and include the following data for each question. (A) Word pair number. (B) Spelling 1: Spelling of a word including R out of two words of the word pair having the above word pair number. (C) Spelling 2: Spelling of a word containing L of two words of the word pair of the above word pair number. (D) Correct answer classification: Indicates whether a voice of a word including L is uttered as a correct answer or a voice of a word including R is uttered as a correct answer. (E) Sound source: Index data of the speaker sound source used in the speaker sound source file 50 (also stored in the word table 20) and a word including L of the sound source data, or R The data showing whether it is a word containing is shown. Here, the former case is described as (L) and the latter case is described as (R).

As shown in FIG. 4, in step S11, the number of questions for each difficulty level, that is, the number of questions for each difficulty level, and the previous question are set, for example, based on the rank based on the rank-based question number table 22 shown in FIG. The number of power word pairs and the number of word pairs in one-sided question are taken in. In the example of FIG. 9, it is assumed that the previous rank is 5 and the current rank is 6. Next, in step S12, the previous question question table 43 in the individual learning history table 43 of the learner concerned.
The word pair to be used this time is randomly determined from the word pair of the previous question. In the example of (a) of FIG. 13, Problem 1 to Problem 4 are the same as the previous problem.

Then, in step S13, the remaining problems are randomly determined from the rank-based problem number table 22 based on the rank and the difficulty-based problem number. In the example of FIG. 13B, the problems 5 to 10 are the problems determined in step S13. Next, in step S14, in order to prevent the answer of the word containing L and the word containing R from being repeated in the learning problem, one of the questions in both pairs is selected from the question created in step S13. Select and decide the word pair of the one-pair question that is the problem. In addition, since the rank of this learning is 6, the number of word pairs of one pair question is 3 from the rank-based question number table of FIG. 9, and therefore, the problem is set so that the number of one pair questions is 3. select. In the example of (b) of FIG. 13, there is a problem of questions of both pairs of 5 pairs, but among them, questions 3 to 10 are questions of the same questions of both pairs. In the processing example of step S14 of FIG. 13C, the processing is performed as follows. (A) Problem 1 of the problems presented in both pairs of problem 1 and problem 2
Is selected, and question 2 is undecided. In the example of (c) of FIG. 13, it is left blank. (B) Problem 6 out of the problems in both question 5 and problem 6
Is selected, and question 5 is undecided. In the example of (c) of FIG. 13, it is left blank. (C) Problem 6 out of the problems in both question 5 and problem 6
Is selected, and question 5 is undecided. In the example of (c) of FIG. 13, it is left blank. As a result, the number of questions per pair is 3
Becomes

Further, in step S15, in order to determine the above-mentioned undetermined questions so that the number of questions according to the degree of difficulty defined in the above-mentioned number-of-questions by rank table 22 is determined, the one-sided pair determined in the above step S14 The word pair of the same difficulty as the word pair of the question is randomly selected and determined. In the example of (d) of FIG. 14, Problem 2, Problem 5, and Problem 8
And decide. Further, in step S16, as shown in FIG. 14 (d), the number of speakers is randomly determined so that the number of speakers is a predetermined number defined in the rank-specific question number table 22. decide. FIG. 14 (d)
Then, since the rank is 6, the index data A-
2, a speaker 1 corresponding to A-7, A-4, A-8, a speaker 3 corresponding to index data C-1, C-5, C-9, C-10, and index data D- 7, D-10
The sound sources of the three speakers including the speaker 4 corresponding to the above are used.
After the process of step S16, the process returns to the main routine.

FIG. 5 is a flowchart of the learning process (step S7) which is the subroutine of FIG. In FIG. 5, in step S21, the order of the 10 questions determined in the learning question creation process of step S6 is determined to be random. Next, in step s22, one of the ten questions whose order has been determined is taken in from the lowest order number. And
In step S23, the screen display positions on the CRT display 11 of the two words of the determined question question word pair are randomly determined. That is, it is randomly determined whether the following (a) or (b) is selected. (A) Display the spelling of a word containing L on the right side of the screen and the word containing R on the left side of the screen. (B) Display the spelling of a word containing L on the left side of the screen and the word containing R on the right side of the screen.

Next, in step S24, the spelling of two words of the word pair of the question is displayed on the screen of the CRT display 11 at the position determined in step S23. Further, in step S25, one of the two words of the word pair in question is to be uttered. That is, the MPU 10 transfers the digital data of the sound source from the speaker sound source file 50 to the voice synthesizer 14 based on the index data of the word pair of the question, and in response, the voice synthesizer 14 causes the digital data of the sound source to be transmitted. Based on the above, the voice of the above-mentioned problem word is generated in the form of an electric signal and is output to the speaker 15 to speak. Then, in step S26, it is determined whether or not the waiting time, which is, for example, 5 seconds, has elapsed from the utterance in step S25, that is, whether or not a time-out has occurred, and when the time-out occurs (YES in step S26), the word in question again. In order to produce the voice of, the process proceeds to step S25. On the other hand, when the timeout has not occurred (N in step S26
O), it is determined in step S27 whether or not the answer has been input using the mouse 13 or the keyboard 11, and if not input (NO in step S27), step S2
The loop processing from 6 to step S27 is performed in step S2.
Execute until timeout in 6. On the other hand, step S2
If it is already input in step 7 (YES in step S27)
In step S28, it is determined whether or not the input answer is correct, and the result of the determination, that is, the answer to the question is displayed on the CRT display 11, and then step S28.
Proceed to 29.

In step S29, it is determined whether or not the answer is correct, and the control flow is branched. If the answer is incorrect, the buzzer sounds by using the voice synthesizer 14 and the speaker 15 in step S31, and the process goes to step S23. Returning to the same question, the processing from step S23 to step S28 is executed. On the other hand, when the answer is correct (YES in step S29), a chime sound is emitted using the voice synthesizer 14 and the speaker 15 in step S30, and the process proceeds to step S32. In step S32, it is determined whether or not all the questions have been given in the learning. If there is a question that has not been given, that is, if all the questions have not been given (NO in step S32), the process returns to step S22. Perform the process of asking another question. On the other hand, if all the questions have been answered in step S32 (step S3
(YES in 2) Return to the main routine. The input process of the keyboard 12 and the mouse 13 is executed by an interrupt process different from the control flow.

FIG. 6 is a flowchart of the difficulty level changing process (step S8) which is the subroutine of FIG. As shown in FIG. 6, in step S51, the word information table 42 in the individual learning history file 31 of the learner is updated based on the learning result in the learning process in step S7. For example, the word information table 42 is updated to (a) of FIG. 11 based on the number of incorrect answers and the number of correct answers of learning.
Next, in step S52, the correct answer rate is calculated for each word pair based on the learning results of all learning by the learner up to now, that is, based on the updated word information table 42. Incidentally, from step S52 to step S
The processing up to 63 is executed for each word pair. Next, in step S53, it is determined whether or not the number of questions is five or more. If the number of questions is not five or more, the number of learning is relatively small. Therefore, the difficulty level of each word pair of the learner should be changed. Without it, it progresses to step S70. Note that, in the present invention, the number of times the judgment is given in step S53 is not limited to five, and may be a plurality of times other than five.

When the number of questions is 5 or more in step S53 (YES in step S53), step S54
Then, it is determined whether the correct answer rate of the word pair calculated in step S52 is 80% or more. In the present invention, the correct answer rate of the threshold value of the determination in step S53 may be other than 80%, and may be a predetermined number of% exceeding 50%. When the correct answer rate of the word pair is 80% or more (YES in step S54), the problem of the word pair can be estimated to be relatively easy for the learner. Therefore, in order to improve the learning effect, in step S55. Decrease the difficulty level of the corresponding word pair by one rank. For example, in FIG. 10, the word pair with the word pair number 3 is lowered from the difficulty level 2 to the difficulty level 3. Then, the number of questions of the corresponding word pair in the word information table 42 in the individual learning history file 31 of the learner is reset to 0, and the incorrect answer count and the correct answer count are reset to 0. For example, in the example of FIG. 11, the number of times the word pair with the word pair number 3 is presented is reset to 0, and the number of incorrect answers and the number of correct answers are also reset to 0. Then, the process proceeds to step S70.

On the other hand, when the correct answer rate is less than 80% in step S54 (NO in step S61), step S6
In 1, it is determined whether or not the incorrect answer rate of the word pair is 80% or more. In the present invention, step S61
The correct answer rate of the threshold of judgment in
It may be a predetermined number of percentages above 0%. When the incorrect answer rate of the word pair is 80% or more (Y in step S61)
ES), since it can be inferred that the problem of the word pair is relatively difficult for the learner, in order to improve the learning effect, the difficulty level of the word pair is increased by one rank in step S62. For example, in FIG. 10, the word pair with the word pair number 2 is increased from the difficulty level 1 to the difficulty level 2. And
In addition to resetting the number of times the relevant word pair has been asked in the word information table 42 in the individual learning history file 31 of the learner to 0, the number of incorrect answers and the number of correct answers are also reset to 0. For example, in the example of FIG. 11, the number of times the word pair of the word pair number 2 is set is reset to 0, and the number of incorrect answers and the number of correct answers are reset to 0. Then, step S70
Proceed to. It should be noted that in the difficulty level changing process, FIG.
In the example of, the difficulty level of the word pair with the word pair number 7 is
Increased from difficulty level 4 to difficulty level 5, word pair number 9
The difficulty levels of the word pairs of 10 and 10 are increased to the difficulty level of 6 or higher.

In step S70, it is determined whether or not the difficulty level changing process has been executed for all word pairs. When the process is finished (YES), the process returns to the main routine, while when it is not finished (NO). ) Returning to step S52, the difficulty level changing process is executed for another word pair.

In the above difficulty level changing process, as shown in steps S54 and S55, when the number of times the question of a certain word pair is presented five times or more and the accuracy rate is 80% or more, the corresponding word Although the difficulty level of the pair is lowered by one rank, the present invention is not limited to this, and, for example, when the accuracy rate of the problem of the word pair is 90% or more, the difficulty level of the word pair may be lowered by two ranks. . Further, for example, when the accuracy rate of the word pair problem is 95% or more, the difficulty level of the word pair may be lowered by two ranks. In other words, you may skip the difficulty level.

In the above-described difficulty level changing process, as shown in steps S54 and S61, the number of times a question of a certain word pair is presented five times or more and the incorrect answer rate is 80%.
In the above case, the difficulty level of the corresponding word pair is increased by one rank, but the present invention is not limited to this, and for example, when the incorrect answer rate of the word pair problem is 90% or more, the difficulty level of the corresponding word pair is increased. Two
You may raise only the rank. Further, for example, when the incorrect answer rate of the word pair problem is 95% or more, the difficulty level of the corresponding word pair is set to 2
You may raise only the rank. In other words, you may skip the difficulty level.

In the present embodiment, as in the difficulty level changing process of FIG. 6, the correct answer rate of each word pair to which a predetermined difficulty level is assigned is a predetermined correct answer rate threshold, such as 80%. When the value is higher than the value, the rank of the learner will be increased,
When the incorrect answer rate of each word pair is equal to or higher than a predetermined incorrect answer rate threshold value such as 80%, the rank of the learner is lowered. The process is executed, for example, before the process of step S10.

The unique effects of the embodiment configured as described above will be described below. (A) As for the appearance order of the word pairs in the learning process in step S7, as shown in FIG. 4, the questions are randomly given every time so that the hearing ability itself can be improved without relying on the previous memory. . (B) By performing the entrance examination process of step S3, a certain level of test is performed at the start of learning to determine the listening ability rank of the learner, and start from that rank. This enables the learning effect to be obtained in a shorter time.

(C) In the learning question creating process of step S6, the learning word pair used for the question is selected according to the current rank of the learner. Here, the ability of the learner and the tendency of continued learning are judged from the word pairs divided into a plurality of difficulty levels, and the word pair most suitable for the current ability level is selected and presented. Then, in order to obtain a higher learning effect, the learning result in the learning process, in other words, learning is performed by repeating the test in the learning process, and the correct answer rate of a certain word pair is, for example, 80% or more. At this time, the problem of the word pair is judged to be relatively easy for the learner, and the difficulty level is lowered by one rank. On the other hand, when the incorrect answer rate of a certain word pair is, for example, 80% or more,
The word pair problem is judged to be relatively difficult for the learner, and the difficulty level is increased by one rank. Thereby, the contents in the difficulty level-based index table 41 are made appropriate for the learner, that is, the difficulty level set for each word pair is not too easy for the learner,
And it can be set automatically so that it is not too difficult, and thus the learning continuity of each learner is obtained.
That is, by repeatedly executing the learning process to learn, the difficulty level of each word pair becomes an appropriate difficulty level for each learner, whereby each learner can use the learning system for a long period of time. It is possible to avoid pain, and the learning effect can be greatly improved. As a result, the overall learning time is shortened.

(D) Furthermore, learning is performed by repeating the test in the learning process, and when the correct answer rate of a certain word pair is, for example, 80% or more, the rank of the learner is 1 I'm only raising the rank. On the other hand, when the incorrect answer rate of a certain word pair becomes, for example, 80% or more, the rank of the learner is lowered by one rank. As a result, by improving the ability due to the learning effect of the learner's learning, the question contents can be automatically set to the appropriate learning rank for the learner. As a result, it is possible to prevent each learner from using the learning system for a long period of time, and it is possible to significantly improve the learning effect. This allows
We are trying to reduce the overall learning time.

To summarize the effects of (c) and (d) above, word pairs are classified according to the degree of difficulty of listening, and a plurality of learning ranks are set, starting from the stage suitable for the learner. , As the steps are automatically raised and lowered according to the progress, it is possible to effectively acquire the basic listening ability while keeping the learner's motivation high.
It is applicable to a wide range of age groups.

(E) Also, although the rank of each learner rises as a result of repeating the learning process to learn, the number-of-questions-by-ranks table 22 in Table 3, FIG. 2 and FIG.
As shown in, a word pair with a low difficulty is added to a high rank at a certain ratio in order to stimulate the learner to continue learning. It is possible to make it easy for each learner to use the learning system for a long period of time,
The learning effect can be greatly improved. (F) In the present embodiment, the analogy information other than the sound is excluded, and the listening training of the words pronounced by a plurality of speakers is focused, so that the listening ability can be surely improved. . (G) When selecting a question question of a word pair for each difficulty level in each rank, the selection ratio is set in advance, and the word continuity of a low difficulty level is appropriately mixed in a high rank, thereby sustaining learning. It is devised to keep.
