Abstract

Abstract: PROBLEM TO BE SOLVED: To provide a computer-based learning system dealing with an alternative problem of selecting one correct answer from a plurality of candidates, in which a data file has high compatibility with a data file of another system, and is a beginner of computer use. However, we provide a system that can easily create alternative questions. SOLUTION: A character string surrounded by a specific symbol in a question sentence manuscript data file is extracted, and an array of the obtained character strings is stored in a memory as a list of answer character strings. Character strings surrounded by specific symbols in the question sentence manuscript data file are displayed as blanks, and the other character strings are displayed as question sentences as they are. The answer character string candidate list is displayed at the position of the blank space where the learner focuses. In this list, in addition to the correct character strings, character strings other than the correct character strings in the answer character string list are randomly extracted and included.

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 in a blank portion which is set in an eccentric manner 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, judge and display whether the selected answer is correct, and if incorrect, display the correct answer and teach Such a learning system has been considered. Specifically, a learning software named “Gokutaku” is known. "Gotaku" means five choices in Chinese characters, that is, five choices.

[0003] In a conventional learning system such as a gadget, in addition to the text which is a blank question and a correct answer character string corresponding to a blank, a character string of an incorrect answer which constitutes the option is replaced with a correct answer character string. It was necessary to prepare more than one for each. For example, prepare the following data file. @@ Problem Toyotomi Hideyoshi destroyed Hojo of Odawara in [] and unified the whole country. @@ Options 1590 1600 1492 1192 794 @@ Problem Hideyoshi Toyotomi destroyed [] of Odawara in 1590 and unified the whole country. @@ Options Hojo Oda Fujiwara Tokugawa Takeda

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

[0005] When an incorrect answer character string is recorded in this way, the larger the number of questions that can be given and the greater the number of incorrect answer character string candidates, the more memory is required for incorrect answers. . The biggest problem is that preparing the wrong answer in this way is a very heavy burden on the creator of the data file. Often, they are more concerned about creating incorrect answers than creating 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 Application Laid-Open No. 9-330011. In this system, in order to eliminate the need for a dedicated memory for a wrong answer character string, all headwords in the dictionary data, part of speech information of words, address information of words, that is, arrangement order information are used. A blank correct answer word is one of the headwords, and a wrong answer is automatically selected from other headwords by the system based on a part of speech or an address as necessary. If the information of the headword includes information such as the field of the word in addition to the part of speech, the frequency of questions in the entrance examination, the difficulty level, etc., the system can automatically prepare more appropriate wrong answer options.

This is a configuration that can be made only because the data is a dictionary. Generally, a dictionary has a configuration in which there are headwords, and information such as pronunciation, part of speech, meaning, and examples is recorded as attributes in each headword. Therefore, when a learning system is configured by utilizing this system, it is necessary that the data be in the dictionary configuration as described above. However, it is extremely inconvenient for the data creator to limit the data to such a format.

[0008] In the manuals and collections of problems, explanations and problems are handled for each field. It is common to understand and memorize knowledge in each field. On the other hand, the dictionary is edited mainly for the purpose of searching for and referring to terms. Therefore, the headwords are arranged in Japanese alphabetical order in Japanese and in alphabetical order in English. I don't often learn the dictionary itself. However, in the case of an electronic dictionary, if attributes are provided with field information or index information, the questions are sorted and arranged in order according to the field or the order intended by the data creator so that the knowledge can be easily understood and memorized. be able to.

[0009] In a dictionary, it is not an easy task for a term expert to add such information to each headword. Even if such information is already recorded, in order for the user to update the content, it is necessary to check and update information on all headwords, which is not an easy task.

[0010] Dictionary data is not easily created or updated. There is a lack of responsiveness required for learning software. For example, it is often the case that a difficulty is appropriate for one learner, but inappropriate for another. It is desirable that the learning system data can be easily created and updated easily. The method using dictionary data is not practical because the range of correspondence to the learning ability of the learner is narrow.

[0011] In the case of a learning function attached to an electronic dictionary,
Question sentences cannot be long sentences that need to be scrolled on the screen. You can't even set multiple blanks for different correct answers in a long sentence. The question sentence has one blank in a relatively short sentence. For these reasons, it is necessary to edit a long sentence obtained from a book or the Internet into a short sentence to create a question sentence, which places a heavy burden on the data creator.

[0012] An alternative problem is not displayed, but an example in which a problem and an answer can be newly created and updated relatively freely, rather than creating a question and an answer from dictionary data alone, is disclosed in Japanese Patent Application No. Hei 4-4-2.
There is an example of a 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, word information corresponding to a hole of the fill-in-the-blank question, ie, a blank is recorded.

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

The learning support apparatus searches for a character string of blank word data in a question sentence. 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 are created from the above data. (1) Hideyoshi Toyotomi who succeeded [] destroyed Hojo of Odawara in [] and unified the whole country. (2) Odawara Nobunaga succeeded [1] in Odawara in 1590
He destroyed [] and unified the whole country. (3) Hideyoshi Toyotomi succeeded Nobunaga Oda in 1590 []
Destroyed Mr. Hojo and unified the whole country. (4) Hideyoshi Toyotomi, who succeeded Nobunaga Oda, []
Destroyed Mr. Hojo and unified the whole country.

[0015] The present invention can be extended to a learning system for displaying multiple choice questions in which alternatives are displayed and one correct answer is selected.

"Hideyoshi Toyotomi who succeeded Nobunaga Oda was [A]
[I] destroyed [U] and unified the whole country. ", And when the learner's point of focus (focus) comes in the blank space of a, a number such as 1590 1580 1600 1610 1570 is displayed as an option list.

1580, 160 for correct answer 1590
As an example of a specific method for automatically generating the incorrect answer choices of 0, 1610, and 1570, first, the number of digits of the correct answer value is obtained, and when the number of digits is four, the correct answer value is 5, 10, 1
There is a method in which numerical values obtained by adding and subtracting 5, 20, 25, 30, 35, and 40 are generated, and five of them are selected at random by a method using random numbers.

In the blank of a, prepare a sufficiently long question sentence,
If the dictionary data is created so as to include a sufficiently large number of place names, place names other than the correct place name can be randomly extracted from the place names in the dictionary data by the designated number and used as wrong answer options. The same applies to blanks in c.

In this method, there is no need to have a wrong answer option like "Goku". Unlike the case where only dictionary data is used as data, the present invention is not limited to a configuration of a comparatively short example of a headword and its attribute. You can set multiple blanks in a long question sentence. Since the question sentence is a simple text file itself, it is relatively easy to use data of another program for data of this system or to transfer it to data of another program. That is, data compatibility is high.

However, this method has a problem in that data is divided into two types and managed. As the question sentence becomes longer and the number of words registered in the dictionary increases, it becomes difficult to see which words in the question sentence are designated as blank target strings and which words are not designated by looking directly at the data There is a disadvantage that. In other words, when reading a question sentence, it is unknown which character string in the question is a blank question, 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 dictionary data appears in a plurality of places in a question sentence, and a part of the character string is a blank question, information on which one is to be filled in is blank. It can be difficult to manage. For example, it is assumed that a character string “Hideyoshi Toyotomi” is registered in the dictionary data, and that the question text contains ten Hideyoshi Toyotomi.
If the second, fourth, and seventh Toyotomi Hideyoshi are left blank, but the other Toyotomi Hideyoshi wants to display the information as it is, incorporating the management of the second, fourth, and seventh information complicates the dictionary data structure. . This makes the system difficult for beginners to use.

Although a method of preparing dictionary data in advance on the system side is conceivable, a problem sentence in the field of dictionary data that is not prepared cannot be created as data. Dictionary data must be prepared by the creator of the data.

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

As the problem sentence becomes longer and the number of words left blank increases, it becomes difficult to confirm which character string is to be entered in which space by directly looking at the data. Each time a code is displayed while reading a question sentence, the line of sight is shifted to the corresponding code information located at a remote position, the line of sight is returned to the original position of the question, and the question is read again. Since such reading is forced, the movement of the line of sight frequently occurs.

The problem sentence has a code embedded therein and is no longer a simple text file. Therefore, in order to use the data of another program for the data of this learning system or to convert it to the data of another program, the conversion from a simple text file to the data file as described above and the reverse conversion must be performed. It is necessary to prepare a program to perform. That is, data compatibility is low.

A variety of learning software has been created since 1996, the year after Microsoft released Windows95, but most of the learning software has disappeared in a few years.
One of the reasons is that it is difficult to create data. While learning with the learning software, sooner or later you will always feel that existing data alone is not enough. At that time, if the data cannot be easily and freely created, the learning software will not be used.

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

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

For example, data of a system for storing data in a binary format is data having the lowest compatibility. Saving data as a text file is more compatible than a binary file. However, if a text file is embedded with a code or saved in a special format as in the above example of link use data, compatibility will be reduced.

The third cause is a problem that it is difficult to understand the functions and usage of the learning software. United States Macrom
edia's authoring software Director handles a variety of functions, including text and still images, as well as video and audio. However, on the other hand, it is difficult to use, and you need to learn how to use it for a certain period of time. This places a burden on the user. A 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 the 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, an operation of inputting a Japanese character string including kanji from a keyboard is not a simple operation even if touch typing can be performed. Many conventional learning software require an operation that is 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 compatibility of data is high, the operation and the function are simple, and the invention satisfying these conditions is disclosed in There is an example of -333540.

The data handled by the disclosed method is a text file in which words to be blank are enclosed by specific symbols (for example, [and]). Hideyoshi Toyotomi succeeded Nobunaga Oda at 159
In 0, he destroyed Odawara's Hojo and unified the whole country. For example, [Hideyoshi Toyotomi], who succeeded Nobunaga Oda,
[1590] He destroyed [Hojo] of Odawara and unified the whole country. Just add [] to the text file to complete the data for the learning system.

There was no technology that could easily create data for a learning system before this technology. In order to restore the text file to the original text file, a replacement function of a known text editor may be used.
By specifying [or] in the character string before replacement and making the character string after replacement an empty string, [and] can be removed. There is no problem that arises when managing data in two types. It uses a data format that is extremely easy for both data creators and learners. As a result, data can be easily created and updated, so that anyone can easily use the use of a personal computer as a learning tool for checking the presence or absence of knowledge, which was difficult in the past.

However, the disclosed method displays a question sentence in which a character string surrounded by symbols is left blank, and responds to a learner's operation, for example, an operation of pressing a line feed key on a keyboard. Just display. The learner must determine and record whether the learner has knowledge of each blank.

If the configuration is such that a list of options is displayed and the learner selects a correct answer, the learning effect given to the learner produces a clear difference. The learning system compares the correct answer corresponding to the blank with the answer selected by the learner, and determines which knowledge the learner has acquired and which knowledge has not been acquired,
Record, tabulate and display.

In the technique disclosed in Japanese Patent Application Laid-Open No. H10-333540, the judgment, recording, and totaling of the burden on the learner using the system are automated by the learning system. Furthermore, by translating beyond the limitation of a learning system to the learner's own independence, the learner is allowed to select an answer, and the learning situation is objectively determined using the data of the selected answer. Can be developed into a system for managing

[0038]

In the prior art, in the case of a system having a function of displaying an option question and allowing a learner to input a correct answer, a problem that requires the creation of an incorrect answer in creating the data is a problem. There is a problem that it is not easy to newly create or update data because it is limited to dictionaries, a problem that two types of data are created to make the format complicated and difficult for ordinary users to manage, and a problem such as data compatibility.

In the case of a learning system in which data is easy to create, easy to understand, good in compatibility, and easy for the learner to handle, there is a problem in that there is no function of displaying an option question and allowing the learner to select an answer.

The present invention has been made in view of the above-mentioned problems. It is a learning system for displaying an option problem, and is easy to create and update data, easy for even a beginner to understand, and compatible. The purpose is to be good.

[0041]

According to one aspect of the present invention, there is provided a computer which includes a blank in a question sentence, displays a list of options for the blank, and allows a learner to select the blank. In a learning system that displays alternative questions by using (1) a question sentence manuscript data in which a blank portion in the original sentence of a question is sandwiched by specific symbols, a portion sandwiched by the specific symbol is blank. (2) learning means for randomly selecting a predetermined number of character strings different from the correct answer from a group of character strings sandwiched between the specific symbols and creating a list of options. System.

According to a second aspect of the present invention, there is provided a learning system which includes a blank in a question sentence, displays a list of choices for the blank, and allows the learner to select a choice using a computer. (2) Blank question sentence creating means for leaving a blank space between the specific symbols in a question sentence manuscript data in which a blank space is sandwiched by specific symbols in the original text of the question; A learning system comprising means for sorting a group of interposed character strings, randomly selecting a predetermined number of wrong answers from a specific range before and after the correct character string, and creating a list of choices.

According to a third aspect of the present invention, there is provided a learning system which includes a blank in a question sentence, displays a list of choices for the blank, and allows the learner to select a choice using a computer. (2) Blank question sentence creating means for leaving a blank space between the specific symbols in a question sentence manuscript data in which a blank space is sandwiched by specific symbols in the original text of the question; Means for sorting the interposed character strings in the 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 correct character string, and creating a list of options. The learning system.

The invention described in claim 4 is the learning system according to any one of claims 1 to 3, wherein the question sentence manuscript data is a text file. If a text file is used as the question manuscript data file (hereinafter, simply referred to as a data file) in the computer-based learning system of the present invention, the data file simply has blank-designated symbols inserted into the text file. Even beginners can easily create and update. Therefore, it is possible to easily create a question according to individual requirements of students of various academic levels in a short time. Also, data compatibility is high. Therefore, it is easy to incorporate data of another system as data of the present system, and the data is easily accumulated and reused in a long-term view.

Since the answer choices are randomly selected from all the words specified in the blank and displayed, there is no need to create wrong answer data, and various options are provided as the number of words specified in the blank increases. Will appear.

In the computer-based learning system according to the present invention, the option creating means is provided for each blank.
In preparing a predetermined number of incorrect answers, the answer character strings are sorted in the order of character codes, and in the sorted order, a character string in a predetermined range before and after the correct answer character string. Choose a wrong answer at random from the list and create a list of choices along with the correct answer.

In this computer-based learning system,
Since an incorrect answer displayed in the option list tends to have the same initial character as the first character of the correct answer, an incorrect answer of a word similar in pronunciation can be given as an option. It is considered effective if the data is in a foreign language or if the part specified in the blank is an abbreviation or numerical value in alphabetical characters.

In the computer-based learning system according to the present invention, when the option list preparing means prepares a predetermined number of incorrect answers for each blank,
Sort the blank character string in the order of the number of characters of the character and the character code, and in the sorted order, mistakenly answer incorrectly from the character string in the specified range before and after the correct answer character string. Is selected as an option list creating means for creating an option list together with the correct answer.

In this way, since the number of incorrect answers displayed in the option list is likely to be the same as the number of characters of the correct answer, an option list having a substantially constant number of characters can be given.

[0050]

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

This system is a so-called personal computer,
A CPU (Central Processing Unit: control unit) 10 is a central part. When the power of the power supply 20 is turned on, the CPU 10 operates the OS (Operati
on System), and executes an application stored in the hard disk 12, the floppy (registered trademark) disk 13, or the CD-ROM 14 according to character information from the keyboard 15 or numerical information input from the mouse 16. Calculation and character string processing are performed using RAM 11, also called memory, and the processing result is displayed on the display 17,
Alternatively, the data is output to the outside through the LAN adapter 18 or the modem 19.

FIG. 2 is also a block diagram showing a 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
Are recorded in the ROM 21. Input can be performed 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 apparatus can be downsized, so that a palm-sized system can be put to practical use. It is well known that various configurations other than FIGS. 1 and 2 are possible.

Next, the operation of the learning system for displaying a list of options having 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. FIG. 6 shows an example of the content of the text file selected by the learner.

The specific characters designating the blank are [and]. It is assumed that the number of items in the option list is 5 and the range of selecting incorrect answers from before and after the correct answer in the sorted answer list is 10 items before and after the correct answer.

When the above-mentioned text file is read into the array Txt () in step S1, the result is as shown in FIG.

Next, in step S2, an array Q () is created from Txt () by replacing [] and its inside with a single-byte space. This processing is performed as follows, for example. Searches for the [character from the first character of the character string. To search, for example, US Micro
InStr in Visual Basic Version 6 of soft development language
Functions are known. If [is found, replace this character with a space. The character before [is left as it is. Then, all the character strings until [corresponding] is found after [is found] are replaced with single-byte spaces. However, if the character to be replaced is a full-width character, a half-width space
Replace with two. The Mid function is known for replacement. In addition, instead of replacing with a single-byte space of the number of bytes of the character string in parentheses, it may be replaced with a fixed number of single-byte spaces, or the maximum number of bytes and the average byte number of the character string in all parentheses may be replaced. It may be replaced with a half-width space. Of course, characters other than half-width spaces may be used. This process is repeated until the end of the line, and the process for each line is repeated for all the lines.

Although described in considerable detail here, various methods can be considered for the above processing, and although the processing is different in configuration and has advantages and disadvantages, the same processing result is obtained for the same data. Then, it is the same processing in design. The use of variables and arrays in the processing is left to the coding staff to some extent, and the use of such variables and arrays is not the essence of the present invention.

Also, if it is clear how to process the data in a specific manner, it is necessary to explain the specific processing method using variables and arrays to the person in charge of coding as described above. Nor. Of course, if the coding person is a novice in programming, it is necessary to give specific details on the coding method, but in that case, it is not considered to correspond to "a person skilled in the art having ordinary knowledge". As described above, Q () is created as shown in FIG.

Next, in step S3, an answer array Ans () is created by extracting a character string inside [] from Txt ().
This processing is performed as follows, for example. Searches for the [character from the first character of the character string. If found, search for [] from the position following the character position. If [is found], store the characters up to the character immediately preceding [from the next character] in Ans (). In this way, Ans () as shown in FIG. 9 is created. This is also an easy technique for those skilled in the art if it is clear what kind of configuration data is to be processed.

Next, in step S4, the line number of the n-th [] from Txt () is set to the array Line (), and the byte position of [is set to the array Po.
The byte position of] is stored in the array Pos2 () in s1 (). As a result, for example, as for the first blank (the character inside is “H”) in the above example, it is on the third line, and [is 3 bytes from the front,] is at the position of 6 bytes from the front, Line (1) = 3, P
os1 (1) = 3 and Pos2 (1) = 6. This process is also an easy technique for those skilled in the art if it is clear what kind of configuration data is to be processed.

Next, in step S5, an option list array Alt () for the n-th blank from Ans () is created. Ans ()
A wrong answer other than the correct answer is selected at random from the list and is combined with the character string of the correct answer to form an option list. For example, if a user-defined structure is declared as Public Type AltList Ans (1 To 5) As String End Type Public Alt () As AltList, then 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 a list of options corresponding to the first blank (the character inside 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 is made to come to an unspecified position using a random number. Then, information on what is the correct answer is also held in an array.

A method of sorting the answer array by character codes and selecting an incorrect answer from before and after the correct answer is as follows. First, an array Ans2 () is created by sorting Ans () by character code. Then, an arrangement as shown in FIG. 10 is obtained.

Since "H" is an array item with the subscript 19, the preceding five Cu, F, Fe, Ga, Ge and the following five He, I,
Four incorrect answers are randomly selected from K, Kr, and Li using random numbers. In the case of Ag, there is no array before, so the last 10
Four are randomly selected from the values Al to Cl of the array. Zn
In the case of, randomly choose from the previous ten. In this way, an incorrect answer in which the first character relatively matches is likely to be prepared. For example, when "Se" is a correct answer, Sc and Si are likely to be included in incorrect answers.

In order to sort the answer array by the number of bytes and the character code and select an incorrect answer from before and after the correct answer, first
Create an array Ans3 () in which s () is sorted by byte count and character code. The arrangement is as shown in FIG.

In the following, an incorrect answer is selected in the same manner as in the case of sorting only by the character code. In this way, it is easy to obtain an option list having the same number of characters. In the above example, the atom symbol in the periodic table of atoms is blank, so the answer character in the blank is
One or two bytes (unless half-width spaces are considered one byte) and the number of bytes in the character has no significant effect.

However, if the number of bytes in the blank answer character string is significantly different, the number of bytes in the character string may be a hint or affect the appearance of the list. That is,
It is meaningless to prepare a choice of 10 bytes or more as a wrong answer when the character string corresponding to the blank is considered as a one or two byte character string and context, and a short character string of one or two bytes Mixing long strings of more than 10 bytes is not good looking. By sorting the answer array by the number of bytes and the character code and then selecting incorrect answers before and after the correct answer, the number of bytes in the character string will not be a hint,
The appearance of options can be improved.

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

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

Then, as the learner selects an answer,
The selected character string is displayed in a blank space, and the option list is moved to the next blank space to display a new choice. By repeating this process, the answer selected by the learner is displayed in all blanks.

When the learner presses a key on a specific keyboard or presses a button on a specific screen with a mouse, the mode is switched from the answer selection mode to the result display mode. Displays whether the answer is correct. The display method is to change the color so that the correct answer is displayed in black as it is, and to display the incorrect answer in red, or to display a circle with a red line around the blank of the correct answer, There is a method of displaying a cross mark near the blank space of. Also, as a way to view the results of the entire problem,
There are a method of displaying only a list of correct answers in the blank of incorrect answers, a method of displaying the number of questions and the number of correct answers, and a display of a correct answer rate.

[0072]

As described above, according to one computer-based learning system according to the present invention, since a data file merely adds a specific symbol for designating a blank space in a text file, a computer-based novice can use the data file. Even so, a data file can be easily created, and the computer can be used as a learning tool. Since there is no work to re-edit the text of the data into the dictionary format, the work of data creation is greatly reduced.

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

In addition, since the answer list is displayed instead of simply displaying the answer in the blank, the correct answer option and the option selected by the learner are selected in response to the learner selecting one of the options. Can be compared, and by this, how much the learner has acquired the knowledge (% correct answer)
And can process information such as what knowledge has not been acquired.

The data text file does not matter in any field. For history, it is possible to specify only the place name, person name, era, or case name in the blank, or for English, specify only the preposition, noun or verb.

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

According to another computer-based learning system according to the present invention, in selecting an incorrect answer option in an option list corresponding to a blank, the answer character string list is sorted in the order of the number of bytes of the character string and the character code. Then, in the sorted order, a character string having a length almost matching the correct answer choice is incorrectly selected from a predetermined number of answer character strings before and after the correct answer character string. Can be selected as an answer.
