Abstract

PROBLEM TO BE SOLVED: To provide a learning system dealing with a multiple-choice question, to which one correct answer is selected out of a plurality of choices, utilizing a computer whose data file is highly interchangeable with a data file in another system and with which even a novice computer user can easily make a multiple- choice question sentence. SOLUTION: In the learning system, a character string placed between specific marks in a question sentence manuscript data file is extracted and the arrangement of the obtained character string is held in a memory as an answer character string list. The character string placed between the specific marks in the question sentence manuscript data file is displayed as a blank column and the other character strings are displayed as they are as question sentences. On the position of the blank column on which a learner focuses attention, a list of choices of answer character strings is displayed. The list includes, in addition to the character string of the correct answer, randomly extracted character strings other than the correct answer character string in the answer character string list.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer-based learning system used for learning knowledge.

[0002]

2. Description of the Related Art Conventionally, as a computer learning system for learning knowledge, for example, a plurality of answer character string candidates are displayed with respect to a blank portion which is set worm-eating in a part of a sentence displayed as a question. , In response to the learner selecting one of the candidates that seems to be correct, whether or not the selected answer is correct is displayed, and if it is incorrect, the correct answer is displayed and taught. A learning system that does this is being considered. Specifically, learning software named "Gotaku" is known. "Gotaku" means five choices, or five choices, in Kanji.

In a conventional learning system such as Otaku, in addition to the blank sentence and the correct answer character string corresponding to the blank, a wrong answer character string constituting the option is set as a correct answer character string. It was necessary to prepare more than one for each. For example, prepare the following data files. @@ Problem Hideyoshi Toyotomi destroyed the Hojo of Odawara in [] year and unified the whole country. @@ Choice 1590 1600 1492 1192 794 @@ Problem Hideyoshi Toyotomi destroyed [] of Odawara in 1590 and unified the whole country. @@ Choice Hojo Oda Fujiwara Tokugawa Takeda

In the above example, the line from the line next to the line "@@ problem" to the line immediately before the line "@@ choice" is the question sentence character string and is "@@ choice". From the line following the line, "@@
The answer string candidate is just before a line "problem" or until the end of the file, the first candidate is the correct answer string, and the other candidates are the incorrect answer strings.

When the wrong answer character string is recorded in this way, a larger memory is required for the wrong answer as the number of questions that can be presented increases and the number of candidates for the wrong answer character string increases. . And the biggest problem is that preparing the wrong answer in this way puts a huge burden on the creator of the data file. I often worry about making wrong answers rather than making question sentences.

As a system for solving this problem, there is a system of "electronic learning machine" of Casio Computer Co., Ltd. disclosed in Japanese Patent Laid-Open No. 9-330011. This system uses all the headwords in the dictionary data, the word part of speech information, and the word address information, that is, the arrangement order information, in order to eliminate the need for a dedicated memory for wrong answer character strings. The blank correct answer word is one of the headwords, and the wrong answer is automatically selected by the system from other headwords, using the part of speech or address as a selection criterion as necessary. The system can automatically prepare more appropriate choices of wrong answers if the information of the field of the word other than the part of speech, the frequency of the question in the entrance examination, and the difficulty is used as the information of the headword.

This is a structure that can be realized because the data is a dictionary. Generally, a dictionary has headwords, and each headword has a structure in which information such as pronunciation, part of speech, meaning, and example is recorded as an attribute. Therefore, when a learning system is constructed by utilizing this system, it is necessary that the data has a dictionary construction as described above. However, it is extremely inconvenient for the data creator to limit the data to such a format.

In the manual and the problem collection, explanations and problems are handled for each field. Understanding and memorization of knowledge is usually done in each field. On the other hand, since the dictionary is edited mainly for searching and referring to terms, the headwords are arranged in the Japanese syllabary order and in English alphabetical order. I rarely learn the dictionary itself. However, in the case of an electronic dictionary, if the attributes have field information or index information, the questions will be sorted in the order sorted by field or the order intended by the creator of the data to facilitate knowledge understanding and memorization. be able to.

It is not easy for a term expert to add new information to each of the entry words in the dictionary. Even if such information is already recorded, in order for the user to update the content, it is necessary to check and update the information about all the entry words, which is not an easy task.

The dictionary data is not easily created or updated. There is a lack of correspondence required for learning software. For example, a problem that is appropriate for one learner will often be inappropriate for another learner. It is desirable that the learning system data can be easily created and updated easily. The method using the dictionary data is not practical because the range of correspondence to the learning ability of the learner is narrow.

[0011] In the case of the learning function attached to Gokutaku and electronic dictionaries,
Question sentences cannot be long sentences that need to be scrolled on the screen. It is not possible to set multiple different correct answer blanks in a long sentence. The question sentence has one blank in a relatively short sentence. For this reason, it is necessary to edit a long sentence obtained in a book or the Internet into a short sentence and create a problem sentence, which is a heavy burden on the data creator.

Although the alternative question is not displayed, an example in which the question and the answer can be newly created and updated relatively freely as compared to the case where the question and the answer are created only from the dictionary data is described in Japanese Patent Application No. 4-2.
There is an example of the learning support device disclosed in 68049.
In the configuration of the present invention, question sentence data and dictionary data are used. In the dictionary data, the word information corresponding to the hole of the fill-in-the-blank problem, that is, the blank space is recorded.

For example, the following data is created and used. @@ Problem Hideyoshi Toyotomi, who succeeded Nobunaga Oda, destroyed Hojo in Odawara in 1590 and unified the whole country. @@ Blank word Nobunaga Oda, Hideyoshi Toyotomi, Hojo Hojo, 1590, Odawara, Place name

The learning support device searches for a character string of blank word data in the question text. In the above case, the character strings of Nobunaga Oda, Hideyoshi Toyotomi, Hojo, 1590, and Odawara are hit. A randomly selected part of the hit character string is replaced with a blank in the question text. Specifically, the following various problems will be created from the above data. (1) Hideyoshi Toyotomi, who succeeded [], destroyed Mr. Hojo of Odawara in [] and unified the whole country. (2) Odawara, who succeeded Oda Nobunaga, [1]
[] I destroyed Mr. and unified the whole country. (3) Hideyoshi Toyotomi who succeeded Nobunaga Oda was in 1590 []
Mr. Hojo was destroyed and the whole country was unified. (4) Hideyoshi Toyotomi, who succeeded Oda Nobunaga, [] year []
Mr. Hojo was destroyed and the whole country was unified.

The present invention can be developed into a learning system for displaying a multiple-choice question in which alternatives are displayed and one correct answer is selected.

[Hideyoshi Toyotomi who succeeded Nobunaga Oda was [A] year
Mr. [U] of [I] was destroyed and the whole country was unified. When a learner's point of interest (focus) comes to a blank space, a number such as 1590 1580 1600 1610 1570 is displayed as a list of options.

Correct answer 1590, 1580, 160
As an example of a specific method for automatically generating the wrong answer choices of 0, 1610, and 1570, first, the number of digits of the correct answer numerical value is obtained, and when the number of digits is four, the correct answer numerical value is set to 5, 10, 1,
There is a method of generating numerical values obtained by adding and subtracting 5, 20, 25, 30, 35, and 40, and randomly selecting 5 from them by a method using a random number.

Prepare a sufficiently long question sentence in the blank box
If the dictionary data is created so as to include a large number of place names, a specified number of place names other than the correct place name can be randomly picked out from the place names of the dictionary data and used as the wrong answer option. The same applies to the blank column in c.

In this method, it is not necessary to have a wrong answer option like "Gokuta". It is not limited to the structure of a comparatively short example of an entry word and its attribute as in the case of using only dictionary data as data. You can set multiple blanks in a long question text. Since the question sentence is a simple text file itself, it is relatively easy to use the data of another program as the data of this system or to convert it to the data of another program. In other words, the data compatibility is high.

However, this method has a problem in that the data is divided into two types and managed. As the problem sentence lengthens and the number of words registered in the dictionary increases, it becomes difficult to understand which words in the problem sentence are specified as blank target character strings and which are not specified by just looking directly at the data. There is a drawback that. That is, when reading a question sentence, it is unknown which character string in the question sentence is a blank problem, and when reading dictionary data, it is unknown where each character string is in the question sentence.

Another problem is that when a character string registered in the dictionary data appears in a plurality of places in the question text and a part of the character string becomes a blank question, what information should be given as to which is blank? Sometimes it is difficult to manage. For example, it is assumed that a character string "Hideyoshi Toyotomi" is registered in the dictionary data, and "Hideyoshi Toyotomi" is included in 10 places in the problem text.
If the second, fourth, and seventh Toyotomi Hideyoshi are left blank, but the other Toyotomi Hideyoshi wants to display them as they are, the management of the information of the second, fourth, and seventh complicates the structure of the dictionary data. . As a result, the system becomes difficult for beginners to use the computer.

A method of preparing dictionary data in advance on the system side can be considered, but if this is done, problem sentences in the field of dictionary data that have not been prepared cannot be created as data. The data creator will need to prepare the dictionary data.

The alternative problem learning system can be configured by using a known method called link (association).
The data file using the link is as follows. @@ Problem "[002] succeeding [001] destroyed [005] in [003] [004] and unified the whole country. Hideyoshi Toyotomi then ..." @@ Blank word 001 = Nobunaga Oda, personal name 002 = Hideyoshi Toyotomi, personal name 003 = Hojo, personal name 004 = 1590, number 005 = Odawara, place name

As the problem sentence becomes longer and the number of blank words increases, it becomes difficult to confirm which character string is contained in which blank by only looking directly at the data. Every time when reading the question sentence and the code appears, the line of sight is moved to the corresponding code information at a distant position and read, the line of sight is returned to the original position of the question sentence, and the question sentence is read again. Since such reading is compelled, the line of sight is frequently moved.

A code is embedded in the question sentence so that it is no longer a simple text file. Therefore, in order to use the data of other programs for the data of this learning system or to convert them to the data of other programs, the conversion from a simple text file to the above data file and its inverse conversion are performed. It is necessary to prepare a program to do. In other words, data compatibility is low.

Various learning softwares have been created around 1996, the year after the release of Windows95 from Microsoft Corporation, but most of the learning softwares have disappeared in a few years.
One of the reasons is that it is difficult to create data. While learning with learning software, sooner or later, it will always be felt that existing data alone is insufficient. At that time, the learning software will not be used unless data can be created easily and freely.

The second cause is low data compatibility. Data compatibility has been neglected in most traditional learning software. In the case of data of a special format, it is difficult to utilize the data of another system as the data of the learning system or transfer the data of the learning system to the data of the other system. Then, the learning system will not be used and the software data will not be used at the same time.

This is a great waste from a long-term perspective. The data for learning should be accumulated and reused repeatedly. For that purpose, it is necessary that the data of other software can be easily taken in and can be diverted to the data of other software.

For example, data of a system that stores data in a binary format is the least compatible data. Saving data as a text file is more compatible than binary files. However, even in a text file, if you embed the code like the example of the data using the link above or save it in a special format, the compatibility becomes low.

The third cause is that it is difficult to understand the function and usage of learning software. US Macrom
edia's authoring software Director has a variety of functions that handle not only characters and still images but also movies and sounds. However, it is difficult to use and it is necessary to learn how to use it for a certain period. This puts a burden on the user. The personal computer is a tool, not a purpose. Learning software is also a tool, not a purpose. Since the purpose is to acquire the knowledge provided by learning software, learning how to use the learning software itself and learning how to create data should not be a burden.

The fourth cause is that the operation is difficult.
For example, the operation of inputting a Japanese character string including kanji from the keyboard is not a simple operation even if touch typing is possible. Many conventional learning software require operations that are not easy.

Although it is not an alternative problem display, the data is simple and easy to understand even for beginners using a personal computer, the data compatibility is high, and the operation and function are simple. There is an example of -333540.

The data handled by the disclosed method is a text file in which the word or phrase to be left blank is surrounded by specific symbols (eg [and]). Hideyoshi Toyotomi who succeeded Nobunaga Oda was 159
Mr. Hojo of Odawara was destroyed in 0 years and the whole country was unified. For example, if you use Nobunaga Oda [Hideyoshi Toyotomi]
[1590] He destroyed [Hojo] in Odawara and unified the whole country. As you can see, the data for the learning system is completed just by adding [] to the text file.

Prior to this technology, there was no technology capable of creating data for a learning system as easily as this. To replace this text file with the original text file, the replacement function of a known text editor may be used.
You can remove [and] by specifying [or] as the character string before replacement and making the character string after replacement empty. There is no problem that occurs when managing data by dividing it into two types. We have adopted a data format that is extremely easy to handle for both data creators and learners. For this reason, data can be created and updated easily, so anyone can easily use the PC, which was difficult in the past, as a learning tool to confirm whether or not they have knowledge.

However, the disclosed method displays a question sentence in which a character string surrounded by symbols is left blank, and the answer character string is displayed there in response to a learner's operation, for example, an operation of pressing a line feed key on the keyboard. Is only displayed. The learner must judge and record whether or not the learner had the knowledge of each blank.

If the list of options is displayed and the learner selects the correct answer, the learning effect given to the learner produces a clear difference. By comparing the correct answer corresponding to the blank and the answer selected by the learner, the learning system judges which knowledge the learner has acquired and which knowledge the learner has not acquired,
Can be recorded, aggregated and displayed.

According to the technique disclosed in Japanese Patent Laid-Open No. 10-333540, the learning system automates these judgments, recordings, and tabulations that have been a burden on the learner who uses the system. Furthermore, by going beyond what is limited to the learning system that is left to the independence of the learner, by letting the learner select an answer, the learning situation is objectively used by using the data of the selected answer. Can be developed into a management system.

[0038]

In the prior art, in the case of a system having a function of displaying a multiple choice question and prompting a learner to input a correct answer, the problem and the data that require the creation of an incorrect answer in creating the data are There is a problem that it is not easy to create new data or update the data because it is limited to the dictionary, or there is a problem that two types of data are created and the format is complicated and difficult for general users to manage, and data compatibility.

In the case of a learning system in which data is easy to create, easy to understand, and has good compatibility, and is easy for learners to handle, there is a problem in that the function of displaying an option question and allowing the learner to select an answer is lacking.

The present invention has been made in view of the above problems. It is a learning system that displays choice questions, and that data is easy to create and update, easy for beginners to understand, and compatible. The purpose is to be good.

[0041]

In order to solve the above-mentioned problems, the invention described in claim 1 is a computer in which a blank is included in a question sentence, and a list of options for the blank is displayed to let a learner select. In a learning system for displaying multiple choice questions using (1), for question sentence manuscript data in which a blank space in an original sentence of a question is sandwiched by a specific symbol, a space sandwiched by the specific symbol is regarded as a blank space. Learning with a blank question sentence creating means, (2) means for randomly selecting a predetermined number of character strings different from the correct answer from the character string group sandwiched by the specific symbols, and creating a list of options System.

The invention described in claim 2 is a learning system which includes a blank in a question sentence and displays a list of choices for the blank to allow a learner to select a choice question by using a computer (1 ) Blank question sentence creating means for leaving blank spaces between blanks in the original sentence of the question with blanks sandwiched between the blanks with specific symbols; The learning system is provided with means for sorting a group of sandwiched character strings, randomly selecting a predetermined number of wrong answers from a specific range before and after a character string to be a correct answer, and creating a list of options.

The invention described in claim 3 is a learning system which includes a blank in a question sentence, displays a list of choices for the blank, and causes a learner to select the choice question using a computer (1 ) Blank question sentence creating means for leaving blank spaces between blanks in the original sentence of the question with blanks sandwiched between the blanks with specific symbols; A means for sorting the sandwiched character string group in order of the number of bytes and the character code, randomly selecting a predetermined number of incorrect answers from a specific range before and after the character string to be the correct answer, and creating a list of options is provided. Use as a learning system.

The invention described in claim 4 is the learning system according to claim 1, wherein the question sentence manuscript data is a text file. In the computer-based learning system of the present invention, if a text file is used as a question sentence manuscript data file (hereinafter, simply referred to as a data file), the data file is obtained by inserting a blank designation symbol into the text file. Even beginners can easily create and update. Therefore, it is possible to easily create a problem in a short time according to the individual requirements of students of various academic levels. Also, the data compatibility is high. Therefore, it is easy to take in the data of other systems as the data of this system, and the data are easily accumulated and reused from a long-term perspective.

Since the answer choices are randomly selected and displayed from all the phrases specified in the blanks, the trouble of creating incorrect answer data is unnecessary, and various choices can be selected depending on the number of blanks. Will appear.

In the computer-aided learning system of the present invention, the option creating means is provided for each blank.
In preparing a predetermined number of wrong answers, the answer character string group is sorted in the order of character codes, and in the sorted order, a character string in a prespecified range before and after the correct answer character string Randomly select the wrong answer from among, and create a list of options together with the correct answer.

In this computer-based learning system,
Since the first letter of the wrong answer displayed in the option list is likely to be the same as the first letter of the correct answer, it is possible to give the wrong answer of words that are similar in pronunciation as options. It is considered to be effective if the data is in a foreign language or if the blank part is an abbreviation or numerical value in English.

In the computer-aided learning system of the present invention, the option list creating means prepares a predetermined number of wrong answers for each blank,
The blank character string is sorted in the order of the number of bytes of the character and the character code, and in the sorted order, the wrong answer is randomly made from the character string in the specified range before and after the correct answer character string. Is selected, and an option list creating means for creating an option list together with the correct answer is used.

In this way, since the number of characters of the wrong answer displayed in the option list is likely to be the same as the number of correct answers, it is possible to provide the option list with a substantially constant number of characters.

[0050]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a system having an alternative problem learning function according to the embodiment of the present invention.

This system is a so-called personal computer,
A CPU (Central Processing Unit) 10 is a central part. The CPU 10 turns on the power supply 20 at the same time as the OS (Operati) stored in the hard disk 12 or the CD-ROM 14.
on System) is started and the application stored in the hard disk 12, the floppy (registered trademark) disk 13 or the CD-ROM 14 is executed according to the character information from the keyboard 15 or the numerical information input from the mouse 16. Performs calculations and character string processing using RAM 11, also called memory, and displays the processing results on the display 17,
Alternatively, it is output to the outside through the LAN adapter 18 and the modem 19.

FIG. 2 is also a block diagram showing the configuration of a system having an alternative problem learning function according to the embodiment of the present invention. This system has RAM11 as a storage device and OS
Is recorded in ROM21. Input is possible by pressing the button 22 or a part of the pressure-sensitive touch display 23 with a finger or the like. Application programs and data are supplied to the RAM 11 via the communication adapter 24. In this example, the device can be miniaturized, so that a palm-sized system can be put to practical use. It is well known that various configurations other than those shown in FIGS. 1 and 2 are possible.

Next, the operation of the learning system for displaying the option list of the above configuration will be described. FIG. 3 is a flowchart of the entire operation when the learning system is activated and one text file is selected by the learner.

A specific example will be described below. The content of the text file selected by the learner is shown in FIG. 6 as an example.

A specific character designating a blank is [and]. It is assumed that the number of items in the option list is 5, and the range for selecting the wrong answer from before and after the correct answer in the sorted answer list is 10 items before and after the correct answer.

When the text file is read into the array Txt () in step S1, it becomes as shown in FIG.

Next, in step S2, an array Q () is created by replacing [] from Txt () with a half-width space. This processing is performed as follows, for example. Search for the character [from the first character in the string. Search for example US Micro
InStr in Visual Basic version 6 of the soft development language
The function is known. If [is found, replace this character with a space. The character before the [is unchanged. Then, replace all the character strings until [Corresponding] after "is found" with a half-width space. However, if the character to be replaced is full-width character, half-width space
Replace with two. The Mid function is known for replacement. In addition, replacement does not have to be done with a half-width space for the number of bytes in the parentheses, but with a fixed number of half-width spaces. It may be replaced with a single-byte space. Of course, you may use characters other than half-width spaces. This process is repeated until the end of the line, and the process for each line is repeated for all lines.

Although described in detail here, various methods are conceivable for the above processing, and the same processing result can be obtained for the same data although there are differences in the configurations and the advantages and disadvantages. Then, the processing is the same in terms of design. The usage of variables and arrays in the processing can be freely left to the coding person to some extent, and such usage of variables and arrays is not the essence of the present invention.

If it is clear how to process the data of what kind of structure, it is necessary to explain the specific processing method using variables and arrays to the coding person as described above. Nor. Of course, if the coding person is a beginner in programming, it is necessary to specifically instruct the coding method in detail, but in that case, it cannot be considered to belong to "a person having ordinary skill in the art". As described above, Q () is created as shown in FIG.

Next, in step S3, an answer array Ans () is created by extracting the character string inside [] from Txt ().
This processing is performed as follows, for example. Search for the character [from the first character in the string. When it finds it, it then searches for [] from the position after the character position. When [] is found, the characters from [the character after [] to the character immediately before] are stored in Ans (). In this way, Ans () as shown in FIG. 9 is created. This is also a technique that is easy for those skilled in the art if it is clear how to process the data having any configuration.

Next, in step S4, the n-th line number of [] from Txt () is placed in array Line (), and the byte position of [is placed in array Po.
The byte position of]] is stored in array Pos2 () in s1 (). As a result, for example, for the first blank (the internal character is "H") in the above example, it is on the third line, and [is 3 bytes from the front,] is 6 bytes from the front, Line (1) = 3, P
os1 (1) = 3 and Pos2 (1) = 6. This processing is also a technique that is easy for those skilled in the art if it is clear how to process the data having any structure.

Next, in step S5, an option list array Alt () for the n-th blank field from Ans () is created. Ans ()
Wrong answers other than the correct answers are randomly selected from the list and combined with the correct answer character string to form a list of options. For example, if you declare as a user-defined structure, Public Type AltList Ans (1 To 5) As String End Type Public Alt () As AltList, Alt (1) .Ans (1) = "H" Alt ( 1) .Ans (2) = "Cl" Alt (1) .Ans (3) = "Mn" Alt (1) .Ans (4) = "Na" Alt (1) .Ans (5) = "Ag" Will make an array like. This is the list of options corresponding to the first blank (internal character is "H"). It is well known to those skilled in the software industry that various methods can be considered for creating an array and storing values in this case. In this example, the correct answer comes first, but the correct answer does not always come to a fixed position, but it comes to an unspecified position by using a random number. Then, the array also holds information about which number is the correct answer.

The method of sorting the answer array by the character code and selecting the wrong answer before and after the correct answer is as follows. First, create an array Ans2 () in which Ans () is sorted by character code. Then, the arrangement as shown in FIG. 10 is formed.

Since "H" is an array item having the subscript 19, five Cu, F, Fe, Ga, Ge before and five He, I, and
Random numbers are used to randomly select four wrong answers from K, Kr, and Li. In the case of Ag, there is no array in the front, so the back 10
4 values are randomly selected from the values Al to Cl in this array. Zn
In case of, randomly select from the previous 10 pieces. By doing so, it is easy to prepare an incorrect answer in which the first character is relatively matched. For example, if "Se" is the correct answer, Sc and Si are likely to be included in the wrong answer.

To sort the answer array by the number of bytes and the character code and select the wrong answer before and after the correct answer, first select An.
Create an array Ans3 () in which s () is sorted by the number of bytes and the character code. The arrangement is as shown in FIG.

In the following, the wrong answer is selected as in the case of sorting only by the character code. In this way, it is easy to obtain a list of options with the same number of characters. In the above example, the atomic symbol in the periodic table of atoms is blank, so the blank answer character is
It is 1 byte or 2 bytes (unless you consider the half-width space to be 1 byte), and the number of bytes of a character has no significant effect.

However, when there is a significant difference in the number of bytes of the blank answer character string, it is considered that the number of bytes of the character string serves as a hint or affects the appearance of the list. That is,
It is meaningless to prepare a choice of 10 bytes or more as an incorrect answer when it is considered from the context that the text corresponding to the blank is a text of 1 or 2 bytes. Mixing long strings of 10 bytes or more is not good looking. By sorting the answer array by the number of bytes and the character code and then selecting the wrong answer before and after the correct answer, the number of bytes in the string does not become a hint,
You can improve the appearance of your options.

Next, in step S6, the question sentence is displayed on the screen. The question text shows a character string and a rectangular frame at the position of the blank to clearly show where the blank is. Of course, it is also possible to display a rectangle with an underline or a filled inside, instead of the rectangular frame. For example, the Print method is used to display the character string. The Line function is known to display a rectangular frame. The upper left coordinates, width, and height information of the rectangle used as an argument in the Line function are the array of Line (), Pos1 (), Pos2 (), and the width, height, and line spacing of half-width and full-width characters on the screen display. , And the top and left margins of the display screen. This is also a processing method that can be easily understood by those skilled in the art. Figure 4 is a screen displaying a question sentence.

Next, in step S7, a list of options is displayed on the screen. The display position of the option list may be displayed at a fixed position or may be displayed at a blank position that the learner is currently paying attention to. In the latter case, Line (), Pos1 (), Po
Using the above method of determining the position of the blank using the array of s2 (), in the initial display immediately after the file is selected, the option list is displayed in the position of the first blank. The string of items to be displayed is obtained from Alt (). FIG. 5 is a screen that further displays a list of options.

After this, as the learner chooses the answer,
The selected character string is displayed in the blank space, the option list is moved to the position of the next blank space, and a new option is displayed. By repeating this process, the answer selected by the learner is displayed in all the blanks.

Then, in response to the learner pressing a key on a specific keyboard or pressing a button on a specific screen with the mouse, the answer selection mode is switched to the result display mode, and each of the learner's answers is changed. Shows whether the answer is correct. As for the display method, if the correct answer is displayed in black characters as it is, and if it is an incorrect answer it is displayed in different colors so that it is displayed in a different color, or a circle with a red line around the blank of the correct answer is displayed and the incorrect answer is displayed. There is a method to display a cross mark near the blank space. Also, as a way to display the results of the whole problem,
There are a method of displaying only the correct answers in the blank of incorrect answers, a method of displaying the number of questions and the number of correct answers, and a correct answer rate display.

As described above, according to one computer-based learning system according to the present invention, since a data file only adds a specific symbol designating a blank space in a text file, it is a beginner to use a computer. However, you can easily create a data file and use the computer as a learning tool. Since there is no work to edit the text of the data into a dictionary format, the work of creating the data is greatly reduced.

Since the created data file is close to a simple text file, the data compatibility is high. In the long-term view, data for learning is accumulated and is easy to reuse repeatedly.

Moreover, since a list of options is displayed instead of just displaying the answers in the blanks, the correct answer option and the option selected by the learner are selected in response to the learner selecting one of the options. It is possible to compare, and by this, how much the learner has acquired knowledge (how many correct answers have been made)
It can process information such as what knowledge has not been acquired.

The text file of data does not matter in any field. For history, place names, people's names, eras or case names may be specified as blanks, and for English, prepositions, nouns or verbs may be specified as blanks.

According to another computer-aided learning system of the present invention, when selecting an incorrect answer option in the option list corresponding to a blank, the answer character string list is sorted in the order of the character code, and the sorted result is sorted. Since a predetermined number of answer character strings before and after the correct answer character string are randomly selected in the arrangement order, a character string of words similar to the correct answer option can be selected as an incorrect answer.

According to another computer-aided learning system of the present invention, when selecting an incorrect answer option in the option list corresponding to a blank, the answer character string list is sorted in the order of the byte number of the character string and the character code. However, in that sorted order, a random number is selected from a predetermined number of answer character strings before and after the correct answer string, so a character string with a length that almost matches the correct answer choice is incorrect. You can pick out the answer.
