Description

Study and evaluating system on internet to express calculus of symbols and outline sketch by components such as ActiveX control and Java Applet and method

The present invention relates to a bidirectional learning / evaluation system and method for encoding a mathematical symbol and a figure on the Internet, and more particularly, to a mathematical symbol by simply encoding a representation of a mathematical symbol and a figure used in a mathematical learning through the Internet. Significantly reduce the data capacity used for graphs and figures, enabling the construction of large-scale learning databases with a small amount of space, and providing learning contents to learners through the operation of this learning database, and recording learning evaluation data entered by users. The present invention relates to an interactive learning / evaluation system and method for coding and expressing mathematical symbols and figures on the Internet so that interactive learning suitable for user learning ability can be performed based on the analysis.

In general, a learning system expressing mathematical symbols and figures by using the Internet produces a document consisting of characters, images, etc., and uploads it to a web server to deliver the learning contents to the user.

There are two ways of learning mathematics using the Internet: the direct method of expressing a document produced by using general characters and purification images on a web page, and the indirect method of expressing a private document using a dedicated viewer already installed on a user's computer.

Here, the conventional mathematical expression on the Internet by the direct expression method, which is the former, is used as a conventional document editor such as a word processor or a text editor to learn contents to be expressed on a web page by an operator as shown in FIG. While the mathematical symbols and figures to be included in the learning content are produced using a dedicated equation editor and an image editor, the graphic image format (for example, can be expressed on a web page). (GIF or JPG graphic file) (S10 to S11).

Subsequently, the document is inserted in a position to be expressed in a command format (TAG) of a document in HyperText Markup Language (hereinafter referred to as "HTML"), and then inputs characters for explanation on the HTML document. Along with the graphic file was uploaded to the operator's web server to register (S12 ~ S14).

Through the above process, the HTML document uploaded to the web server can learn while watching the web browser screen running on the personal computer of the user connected to the web server through a communication connection means such as the Internet through an image output means such as a monitor. (S15 to S18).

However, mathematical symbols and figures in the form of graphic images embedded in HTML documents produced in the conventional manner require excessive manufacturing costs in order to secure various data storage spaces and other steps, and thus, users of a wide variety of users For this purpose, it has been a limiting factor in producing various and large amounts of learning data for web browsers. In addition, since it was inserted from the operator or the person who produced it without considering the learning ability of the user, only the uniform contents can be registered, but the service that cannot consider the learning ability or the requirements of the user was inevitably provided.

In other words, the learning system that transmits the learning data unilaterally from the operator who operates the conventional web service has clear distinction between before and after learning, unlike language and humanities, which are mainly understood and memorized. After enough completion, it was not suitable as a service for learning the mathematics sector, which has the characteristics of step-by-step learning that can be performed afterwards.

In addition, the learning achievement can be improved only by providing the learning contents step by step after collecting enough data or current information required to evaluate the learning ability from the user or by providing the appropriate level of learning contents after searching the database. Mathematical symbols and figures used have a problem in that real-time service is difficult because it is difficult to build a database for mathematics education because it is necessary to produce a file in the form of an image unlike a textual character.

In addition, despite the fact that mathematical symbols and figures inserted into HTML documents are repeatedly used like letters, there is an inconvenience in that editing operations must be performed by using an equation editor and a graphic editor each time an HTML document is produced.

On the other hand, the indirect expression method that allows the latter to search for the content of mathematics learning using the dedicated viewer, as shown in the accompanying drawings, to produce the learning content to be expressed in the web page using a dedicated document editor. The double mathematical symbols and figures work with the contents to be expressed using the mathematical editor and graphic software, or the mathematical symbol editing function built in the text editor (S20 to S21). In addition, the document file was inserted into the document using the HTML document command format and uploaded to the operator's web server for registration (S22 to S23).

In order to view the web page produced by the indirect expression method, the user installs a dedicated graphic document viewer 24 on the personal computer, and then searches the displayed dedicated document through the web browser 22 (S24 to S29).

However, the indirect expression method, like the direct expression method, has a common problem that it is difficult to make a learning database due to the limitations in the process of producing mathematical symbols and figures. Therefore, the indirect expression method has a common problem. There was also the inconvenience of having to do editing work for the shape production.

Therefore, in order to operate the Internet learning system while the operator and the user exchange data in both directions, the related database construction is a basic prerequisite, but the symbols and figures necessary for learning the mathematics on the web page are expressed in real time together with the document in the form of a plain text. Due to technical difficulties, the mathematics learning database cannot be built.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and its object is to reduce the amount of data used in mathematical symbols and figures by greatly encoding the expressions of mathematical symbols and figures used in mathematical learning through the Internet. In addition, it is possible to build a large-scale learning database, provide learning contents to learners through operation of this learning database, and record and analyze the learning evaluation data input by the user to proceed interactive learning appropriate for the user's learning ability.

A specific instruction delimiter 90 stored in the memory unit 60 so as to be accessed according to each instruction code for vector data for display on A1) (A2) and distinguished from the character data T1 for display on the screen 42. If (91) exists in this character data T1, the magnitude and absolute origin (O) of the display area (A1) (A2) on the screen (42) on the basis of the character string between the command delimiters (90) and (91). ₁ ) (O ₂ ) is calculated, and the string existing between the command delimiters 90 and 91 is compared with the command code list so that the string existing between the command delimiters 90 and 91 is present in the command code list. If this is recognized as a command for drawing a mathematical symbol (D1) and a figure (D2) Among the character strings existing between the command delimiters 90 and 91, the characters T2 and T3 which are not present in the command code list are displayed in the display areas A1 and A2 on which the mathematical symbol D1 and the figure D2 are displayed. Are displayed superimposed on each other.

Here, the linear drawing command calculates, for example, dot-shaped coordinate data connecting the horizontal and vertical absolute coordinate end points with the shortest distance from the horizontal and vertical absolute coordinate starting points on the display area, and then displays them in the display area A1 ( A2) is controlled to display, and in the case of the arc drawing command, the coordinate data in the form of dots is calculated from the horizontal and vertical absolute coordinate end points and radius information from the horizontal and vertical absolute coordinate start points on the display area, and then displayed on the screen (42).

After accessing from 30a, the display area A1 and A2 are displayed. Characters not present in the command code list among the characters 90 and 91 are characters T2 for superimposing the display area A1 and A2 on which the mathematical symbol D1 and the figure D2 are displayed. T3 is calculated by the screen area designation means 30c after accessing the vector data corresponding to the instruction code retrieved from the instruction retrieval means 30b from the memory unit 30a. Characters determined as characters not present in the command code list among the strings existing between the command separators 90 and 91 while being arithmetic processed at the enlargement ratio and stored in the screen output buffer 30e are stored in the screen output buffer 30e. Graphic calculation means 52 for superimposing and storing the stored data, and image output means 42 for displaying the data stored in the screen output buffer 30e and the text data transmitted from the web server 30 on the screen 42. It consists of.

In addition, the code value corresponding to the instruction is sequentially searched from the memory address, and then found, the vector value graphic output data loaded in the memory address is read and transmitted to the graphic operation means 30d.

Here, the display areas A1 and A2 on the screen 42 have location information and size information distinguished therefrom so as not to overlap with the plain text on the HTML document transmitted from the web server 30 by the operator.

The image output means 41 outputs an image so that the user can see the graphic output data stored in the screen output buffer 30e with the naked eye, and has a screen 42 of a predetermined area, for example, a computer made of CRT or LCD. It can be configured as a monitor.

The vector data for displaying the mathematical symbol (D1) and the figure (D2) consists of at least linear drawing information and circular arc drawing information. In the case of the linear display, the vector data has coordinate information indicating a starting point and an ending point on the screen. It is configured to obtain the graphic output information through the normal operation routine that connects the shortest distance.In the case of a circular arc, it has coordinate information indicating the start point and the end point on the screen and information indicating the radius or diameter of the arc. The drawing is configured to obtain graphical output information through an operation routine.

The screen area designating means 30c, the instruction searching means 30b, the graphic computing means 30d, and the screen output buffer 30e may be composed of a microprocessor and a graphic computing processor in a computer.

Referring to the operation of the present invention configured as described in more detail as follows.

First, the operator prepares the learning contents for mathematics education together with the HTML document before starting the service through the web page, and displays the instruction code and the mathematical figure (D2) for displaying the mathematical symbols and figures in the middle of the document. Input the coordinate value for between the separator (90, 91) located in the middle of the HTML document to produce a learning file and loaded in the web server 30, the user is running on the computer and the web browser and the Internet When the user accesses the web server 30 for mathematics education using the same two-way communication means and enters an identification number and password, the web server 30 is a registered or unregistered member from the user management DB 31. In the case of a registered member, the member learns whether to be a member and starts a math learning service, and in the case of an unregistered member, a normal member manager waits until there is a member registration. Performance.

At this time, the web server 30 reads the learning data in the form of HTML document from the evaluation problem DB 34 and transmits it to the user's computer when the initial access menu is selected by the user who is first accessing or by the user. In addition to the HTML document data provided by the web server 30, vector data for displaying the mathematical symbols (D1) and figures (D1) on the screen 42 in correspondence with a predetermined command code to be accessed according to each command code. It is stored in the memory unit 30a of the user.

Thereafter, if there is a command delimiter by searching for whether a specific command delimiter 90 or 91 distinguished from a character for display on the screen in the HTML document stored in the memory unit 30a exists, the command delimiter 90 Based on the character string between the numerals 91, the size of the display area A1 and A2 on the screen 42 and the absolute origin O ₁ and O ₂ are calculated.

That is, as shown in Fig. 5, the display areas A1 and A2 are located in a predetermined area on the screen 42, and the upper left corners of the display areas A1 and A2 (virtually designated, for example) are located. The absolute origin (O ₁ ) (O ₂ ).

At this time, if the command separators 90 and 91 are not found from the HTML document, the HTML document is output through the image output means 41.

In addition, the character strings existing between the command delimiters 90 and 91 and the command code list stored in the memory unit 30a are compared, and the character strings existing between the command delimiters 90 and 91 exist in the command code list. If it is determined to be, it is recognized as one of the instructions for drawing the mathematical symbol D1 and the figure D2.

At this time, if it is determined that the character string existing between the instruction delimiters 90 and 91 does not exist in the instruction code list stored in the memory unit 30a, the character is displayed in the display area A1 (A2) designated on the screen 42. Will be printed).

Then, after it is determined that the character string existing between the instruction delimiters 90 and 91 exists in the instruction code list stored in the memory unit 30a, the character string existing between the instruction delimiters 90 and 91 is a mathematical symbol. After re-searching whether or not there are several instruction codes for drawing (D1), find a corresponding mathematical symbol drawing command, access the vector data of the corresponding address by the mathematical symbol drawing command, Output is made to the display areas A1 and A2.

On the other hand, if the character string existing between the instruction delimiters 90 and 91 is not present in the list of various instruction codes for drawing the mathematical symbol D1, is it a straight line drawing instruction that is one of the instructions for drawing the mathematical figure D2? After rescanning, the linear drawing data stored in the memory unit 30a is accessed and output to the display areas A1 and A2 designated on the screen 42.

That is, at least a start point and an end point on the screen are specified in the straight line drawing data, which is included in the HTML document transmitted from the web server 30 of the operator, and is loaded into the user's computer memory unit 30a after receiving the data. Through the routine for calculating the shortest distance, a vector graphic can be output after recalculating the distance from the absolute origin O ₁ (O ₂ ) as shown in FIG. 13.

Then, if it is determined that the character string existing between the instruction delimiters 90 and 91 does not belong to the mathematical symbol drawing command and the linear drawing command, it is determined by the circular arc drawing command which is another one of the instructions for drawing the mathematical figure D2.
