METHODO FOR PROVIDING TEACHING PROGRAM THROUGH INTERNET AND SYSTEM USING THEREOF}

The present invention relates to a method for providing a teaching plan through the Internet and a system using the same. More specifically, the teacher can easily and conveniently make his or her own original teaching through various educational materials in abundantly pre-written in each subject and topic. Method of providing teaching materials through the Internet, and sharing them with other teachers, and re-creating the teaching materials by adding or modifying new teaching materials under the approval of the original teaching drafters, and using them. It is about the system.

Teaching Program refers to the materials that are referred to by the teachers who point out the students, especially the educational materials. In the past, the teaching program or educational information is checked by the teacher's own management, rather than being directly distributed to the students. Although it is only used for the purpose of teaching, the development of multimedia technology and the Internet has been distributed to students so that teachers can use their own teaching materials as student learning materials.

In this modern multimedia environment, multimedia materials such as CDs and DVDs, that is, teaching materials, are used as learning materials by being executed in a CD / DVD player in a classroom or a multimedia materials player such as a computer. All of them were to carry the syllabus in the form of books, books, and other multimedia materials in class, or to copy and use the teaching materials made by other teachers.

In particular, even if you purchase and use a teaching plan in the form of CD / DVD, there are not only quantitative limitations of the educational materials listed due to the limitation of its capacity, but also the actual required educational materials are often less than that. In many cases, the inconvenience caused.

 In addition, because the materials used for teaching were scattered, we had no choice but to collect narrow educational materials based on the subjective experience and knowledge of the teacher, while other teachers simultaneously used the teaching material as their teaching materials. As a result of the problem of not being able to use, it was a reality that a single school had to buy and use multiple CDs / DVDs.

In order to solve this basic problem, Korean Patent Application No. 2000-0031057 'Virtual Educational Teaching Equipment Writing Method and Method' has a plurality of menus and interfaces for data collection to easily prepare teaching materials through multimedia or hypermedia educational materials. It provides features that can extend the ease of use and the simultaneous use of teaching materials.

However, the above technology is merely a collection of multimedia lesson plans, which are edited and converted into a public notice method, and thus have not been progressively rejected, and the basic teaching materials used in the written lessons are created by the teachers themselves. It may be used in teaching materials, but there are no mentions of the general plans according to the actual application, and teaching materials through the protection of the right to the teaching subjects or the possibility of modification, as well as the preparation of teaching materials through the comprehensive multimedia learning materials. There is a problem that does not provide a direction of expansion.

Therefore, it is not only to collect the multimedia material that is the basic material of teaching material but also to give each material a specific identity to protect the creativity of the creators of the material, and to freely transform the finished teaching material so that various teaching materials can be created. There is a need for a new teaching plan and system.

The present invention has been made to overcome the problems of the above-described technology, and is provided in abundance from the system operator, or the teaching materials produced by the master planner to edit and arrange a variety of educational materials in the Internet environment, and finally own unique teaching plan The main purpose is to pursue the infinite development and free sharing environment of the teaching plan.

Another object of the present invention is to automatically convert the training materials produced by the planners into the basic environment of the system at the time of uploading them to the system to conveniently utilize the training materials having various formats.

Another object of the present invention is to insert a unique identification information in the teaching materials and teaching materials to easily determine where the teaching materials and teaching materials are used, and to automatically determine whether the teaching materials or teaching materials are modified or not. Make sure to protect the rights of the original author of the lesson plan.

A further object of the present invention is to ensure the free use of the correction of the teaching plan, but in consideration of the copyright of the original teaching plan authors to allow the modification only when a certain state of modification is secured or approved by the conflict between the diversity of the modification and copyright protection The best compromise is to.

In order to achieve the above object, a teaching plan providing method through the Internet according to the present invention, the first step of providing a lesson planner in a manner of registering and storing a multimedia database consisting of a variety of formats and educational information to the multimedia database server; A second step of generating a teaching material database through a teaching material writing tool and the teaching material database; In case that the teaching material database is modified by another teaching creator, the teaching material database determines whether the teaching material database has been modified and automatically informs the author of the subject of the approval request, and allows the first author who is notified of the approval request information to decide whether to approve. Modifying the third step; And a fourth step of publishing the teaching material database to members in the Internet environment.

In addition, the teaching plan writing system through the Internet according to the present invention, a multimedia database server containing a multimedia database consisting of a variety of formats and educational information; An instructional database server for recording an instructional database generated by arranging at least one multimedia database in a predetermined format; A metadata generation module for generating metadata for identifying characteristics of the multimedia database by recording any one of a subject, an area, a format, a summary, a keyword, and author information of educational information in the multimedia database; A converting management module having any one of a function of resizing the multimedia database to a specific size or a setting function for assigning an event to automatically convert the multimedia database into a specific format; And an event management module for assigning a unique event to an individual multimedia database constituting the teaching material database through an event handler.

According to the teaching method and the system using the same through the Internet according to the present invention,

1) With abundant basic education materials, teachers can easily create their own teaching materials in the Internet environment, which has the advantage of overcoming the capacity, quality, and cost burden of existing CD / DVD.

2) By modifying or editing the syllabus with reference to other teacher's syllabus, guaranteeing the opportunity to make better teaching syllabus and improve the quality of educational materials.

3) By inserting basic information into each educational material, pursuing convenience of classification and assigning an event to highlight the three-dimensionality of the educational material, even the same educational material can be prepared with unique teaching materials according to the event provisioning contents. ,

4) Encourage the creation of teaching plans by ensuring the rights of the authors who produced them.

5) It has the effect of preventing unauthorized theft or leakage by grasping in real time whether the curriculum is modified.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and the same reference numerals in each of the drawings refer to the same components.

1 is a block diagram showing the schematic components constituting the teaching material providing system through the Internet according to the present invention.

As can be seen from Figure 1, the system 10 according to the present invention is a multimedia database server 20, streaming server 30, teaching database server 50, license management server 40, question bank database server 60 ) And a metadata generation module 70, a converting management module 80, an event management module 90, an identification code generation module 100, and a teaching correction management module 110.

Multimedia database 25 according to the present invention is a database containing a variety of educational content that is the basis of the teaching in the form of a video, animation, flash, image, voice, template, XML, plain text file, Means the data generated by analyzing and combining by experts, field teachers, and lecturers.

The multimedia database 25 is provided in a pre-produced state in a sufficient amount in the system 10 according to the present invention, so that teachers do not have any difficulty in selecting and collecting materials for drafting, and by subject and area. It is stored in the multimedia database server 20 by various category classification methods, such as by difficulty level.

The teaching material database server 50 functions to record the teaching material database 55, which is the educational material finally completed through a process such as editing by a teacher through the multimedia database 25, and the teaching material database 55 There are a number of multimedia databases (25) in which the general information collected from the teaching materials and the content information (multimedia database) placed in the teaching material are embodied in the 1: n structure, that is, the subject matter is expressed in one subject. The detailed information of each multimedia database 25 may be stored in an array form.

2 is a conceptual diagram illustrating an example of an interface for producing a teaching material database according to the present invention.

As can be seen from Figure 2, the teaching plan database 55 according to the present invention is a template form having a specific shape and meaning, a plurality of multimedia data in a variety of interface environment is edited to form a completed teaching plan It consists of a multimedia database 25 in various formats such as video, image, text, etc., and has a search box for easy and quick data search, or how to execute video data, resizing, previewing, and contents of the video file. For example, it is possible to include a function of selecting whether or not to activate an event assigned to each multimedia database 25 and a blackboard function in which a user can directly insert a memo or a picture on a specific multimedia material.

The streaming server 30 is provided for efficient reproduction of the teaching material database 55 to the multimedia database 25. The streaming server 30 plays a video or audio of wmv, avi, asf, and flv file formats in real time.

The streaming server 30 may be divided into a video streaming server and a voice streaming server 35, in this case, the voice streaming server 35 stores a voice form of the training materials or nurtures lectures of teachers. It has the function to save the contents in the form of voice file format such as mp3 and wav.

Of course, the system 10 according to the present invention may use a known method of playing a video after downloading in addition to a video / audio file playing method using the streaming server 30.

The license management server 40 basically has a function of setting a license of each teaching database 55 upon creation of the teaching plan database 55, but more specifically, to protect the authority of the teacher who created the teaching plan database 55. Based on the first draft of the first draft, the second and third draft teaching databases are additionally created or revised. Has a license management function associated with the database 55, which is linked to the metadata generation module 70, the teaching correction management module 110 to be described later to generate an identification code having a license role, teaching correction management module 110 ) To identify the first author of a particular lesson through the identification code and to change or change the location of the lesson To identify and track, as well as to aid in the function of any unauthorized use to deformation of the lesson plan.

The identification code generated by the license management server 40 (specifically, generated by the identification code generation module 100 in the license management server 40) is an identity assigned to each multimedia database 25 or teaching plan database 55. In the case of metadata to be described later, unlike the having a function to easily and conveniently expose the characteristics of each data, it is concealed in the multimedia / teaching database (25, 55) as if hidden landmarks for copyright display It performs a function having a source management or copy protection function of the multimedia / teaching materials database 25,55 as a (land mark).

In other words, the identification code is encrypted in the file structure of the multimedia data and then stored in the header so that the license management server 40 recognizes the identification code of the header so as to identify the location of the multimedia or the plurality of multimedia databases 25. In the teaching database 55 combined with each other, it is possible to implement a coordinate value or the like that can determine the location or inclusion of each multimedia database 25.

Specifically, the identification code according to the present invention consists of an individual identification code assigned to an individual multimedia database 25 and an integrated identification code assigned to a teaching plan database 55 in which a plurality of multimedia databases 25 are combined.

The individual identification codes are used to identify the existence or location of each multimedia database 25. The individual identification codes are encrypted in the header of the file so that the general public can not recognize the existence of the multimedia database 25, but can only be recognized by the license management server 60. consist of.

In addition, the individual identification code facilitates the relationship that the multimedia data / database 25 has been modified through the original material if it has been edited or modified (i.e., recreated as the material B based on the original A data). For example, if the initial identification code consists of 1234, it can be generated by adding subsequent identification codes with the original identification code as '1234-ABCD' after the first modification. In the second modification, the identification code can be issued in succession as '1234-ABCD-KKKK'.

The individual identification code may play a role of indicating whether the multimedia database 25 is used in which teaching database 60 and the history of the multiple modifications.

The integrated identification code gives an identity of teaching materials database 55. Specifically, for example, a coordinate value and a teaching value where a plurality of multimedia databases 25 are located in the teaching materials database 55 frame as shown in FIG. It consists of a value of whether each individual identification code to form a.

That is, the integrated identification code performs a function of determining whether or not the location of the multimedia database 25 is changed and whether the specific multimedia database 25 is included when the teaching plan is modified.

The identification code may be identified and tracked by the license management server 40 itself, but may be identified by the teaching correction management module 110, which will be described later, and may be useful in determining whether the teaching instruction is modified or modified.

The question bank database server 60 has a function of recording a database of an extension concept of the multimedia database 25, and the question bank database 65 is distinguished from the multimedia database 25 containing general education contents. Refers to a database of short-term and multiple-choice questions, answers, and commentary related to the educational content.

The question bank database 65 may be stored in the question bank database server 60 by dividing whether the user is shared or not, and when sharing is set, the question bank database 65 may be used as an open source that can be utilized by the entire teacher, and the sharing setting If this is not the case, it is also possible to use it with the manufacturer's consent by setting an identification code to be described later.

The metadata generation module 70 according to the present invention has a function of generating metadata for recognizing and classifying the multimedia database 25 having various formats by a consistent category classification method.

Metadata refers to the type of multimedia (e.g., mp3 / jpg / mpeg file types), the area (e.g., first grade social studies, etc.), themes (e.g., the National Assembly) for a particular multimedia database 25. And detailed information such as summary, keyword, playback time, creator, size, and the like, and similar information can be stored in the completed teaching plan database 55.

That is, the metadata generation module 70 stores unique identification information in each of the multimedia database 25 and the teaching material database 55. Specifically, the metadata database 25 includes the multimedia database 25 and the multimedia database server 20. When registering to the registration plan or the teaching plan database 50 to the teaching plan database server 55, the known information such as the file size, capacity, etc. are identified and automatically generated in advance, and the information to be obtained by the author such as the subject and summary contents. Allows the creator to generate metadata in a way that requires input.

This metadata provides the characteristics that can be pursued for the convenience of searching, the ease of converting, etc. when a large multimedia or teaching plan is constructed.

The converting management module 80 performs a series of converting processes such as size change (resize) and file type conversion for normalized performance when uploading the multimedia database 25 to the multimedia database server 20. do.

The converting management module 80 converts the size and format of the multimedia database 25 and converts physical files in a manner of storing pictures related to key frames so that real-time streaming to a network can be performed, and the multimedia database creator can Regardless of whether uploaded to the multimedia database server 20 arbitrarily, the object-oriented property and the event and event setting process to automatically inherit the event to be described later is performed.

By the automatic converting function of the converting management module 80, teaching or multimedia data creators can conveniently register materials of various formats created by the multimedia database server 20 regardless of a specific data format. Can have

The event management module 90 has a function of generating or managing an event assigned to each multimedia with unique characteristics. The event management module 90 stores a file in each multimedia database 25 converted object-oriented by the converting management module 80. It is responsible for assigning individual events by type or specific classification.

For example, an image file can be given a mouseover event to change the image size through mouse click or scroll, or a specific filter event. For animation / video / audio files, unique control can be done through mouse or keyboard. You can give an event that can provide a way.

That is, the event management module 90 can have all of the functions of automatically assigning each unique event according to a preset file type or giving various events even if the file type is the same by a user setting method. have.

By the event management module 90, each multimedia database 25 is provided with a unique event in the teaching plan database 55 to give a characteristic that can promote the use of more dynamic and three-dimensional teaching plan.

The teaching correction management module 110 has a function of tracking the corresponding identification code unique to the multimedia database 25 or teaching teaching database 55 or recognizing whether or not it is modified through an interworking function with the license management server 40. Accordingly, the multimedia database 25 to the teaching material database 55 performs functions such as unauthorized use, modification or identification of the range, and processing of approval of the original data creator according to the modification.

More specifically, the function of the teaching correction management module 110 is to determine whether the teaching database 55 is modified through the integrated identification code and the individual identification code, and if it is found to be corrected, the approval request is automatically sent to the first draft of the teaching plan. In response to receiving the approval of the first draft of the teaching plan, the subdivision is made into a function of managing whether the teaching plan database 55 is modified, which will be described in more detail in the specific method according to the present invention.

A method of preparing a teaching plan using the Internet by the teaching plan writing system using the Internet according to the present invention having such a configuration is as follows.

3 is a flowchart illustrating a schematic process for forming a teaching plan using the Internet according to the present invention, and the method according to the present invention will be described with reference to the flowchart with reference to the flowchart.

1. Steps to Provide a Multimedia Database

The first step is to provide a multimedia database to the writer of teaching, comprising a multimedia database, generating metadata, generating individual identification codes, and converting the multimedia database during uploading.

As mentioned above, the multimedia database 25 is prepared in advance by the system operator and provided in advance. However, the multimedia database 25 is not limited thereto, and other users can upload the data created by the teacher themselves to the multimedia database server 20 in a shared utilization manner. It is possible to be provided to.

The multimedia database 25 may select and upload various formats, topics, and area categories which are classified in advance, or at least support an automatic classification scheme in a file format.

At the same time or prior to uploading the multimedia database 25 to the multimedia database server 20, the metadata is assigned to each multimedia database 25. It is possible to generate a, in addition to the subject, summary, and the like to be described by the author through the metadata input step, for example, the metadata is generated through the method directly written by the author in the input window. Such metadata is preferably in XML format in order to increase the compatibility of the data.

The multimedia database 25 having metadata is converted to a specific format required by the system in the process of being uploaded to the multimedia database server 20. That is, as mentioned above, the process of changing the physical file, setting the previous stage for attribute and event assignment, and the like is automatically performed.

When the multimedia database 25 is converted into a specific form, a unique individual identification code is issued by the license management server 40 at the same time (or immediately after) registered and stored in the multimedia database server 20, and the file is stored in the file. Insert into (specifically header part).

The individual identification code is automatically generated by the license management server 40, specifically, the identification code generation module 100, by the decrypted cipher processing method, and the generated individual identification code is dependent on the multimedia database 25. It is stored in the license management server 40 in the state.

2. Steps for drafting

The teaching preparation step is to use the teaching preparation tool provided by the system according to the present invention to create teaching materials by the user's own free format setting and arrangement using various templates and teaching materials database 55 such as user-generated contents, ie UCC. Specifically, the process consists of a multimedia database arrangement and format setting step through an instructional drafting tool, an event provisioning step for each multimedia database, and an integrated identification code generation step.

The teaching tool creates a variety of templates as separate data in a dynamic HTML (DHTML) editor or an XML file editor environment, and performs a function of freely arranging, formatting, and setting up each multimedia database 25.

Since the teaching tool writing tool conforms to the function of a known editor, a detailed description thereof will be omitted. An author who wants to write a teaching book through this teaching tool may search each data or template stored in the multimedia database server 20. By calling through the process of setting the layout and the layout of your own multimedia database 25 within the set layout to conveniently combine a series of processes.

For example, whether or not to give general information such as titles and keywords when drafting lesson plans, set template and layout settings, borders, and backgrounds for lesson plan contents, and utilize web blackboard or writing functions, and each multimedia database 25. It is possible to decide whether to place it larger or smaller than normal size.

In the process of preparing a teaching plan while arranging the multimedia database 25, the teaching planner can assign an event to each multimedia database 25.

As mentioned above, events are automatically arranged according to file properties, or event handlers are provided to the author in advance, for example, when a mouse is touched regardless of file properties, the preview function is performed or when a specific position is clicked. It is possible to give to the individual multimedia database 25 so that the information can be viewed. Of course, even if an event A is assigned to the multimedia database in the teaching material database Z, the event A is limited to a property dependent on Z. In another teaching database X, other events such as B and C are granted. It is possible.

Subsequently, the completed teaching plan is registered and stored in the teaching plan database 50 as the teaching plan database 55. At this time, the integrated identification code is generated and stored and managed for each teaching data in the license management server 40. .

Specifically, in the state that includes the individual identification code of each multimedia database 25, the information that gives the location information of each multimedia database in the layout as a coordinate value is generated as an integrated identification code, which will be described later. Will be identified.

In addition, in addition to using the existing multimedia database 25 during the teaching process, the user may record his or her voice and events. It can be recorded and used as e-learning course materials.

Specifically, the timeline information for recording, the marker information for syncing, the physical voice file, and the mouse event information are separately stored, and the voice recording is performed by using the existing voice recording technology. Change to physical storage on the voice streaming server.

The timeline information and the marker information are stored in XML format for compatibility, and the mouse event information is managed in an XML file by binding to the XML information of the marker in a subtree form, and when the recorded file is played, the XML of the tree structure While the files are reproduced in a multidimensional array, a physical voice file is merged and executed on teaching material data.

Of course, by introducing the above-described converting process of the teacher's own voice or other video to be able to be inserted in a compatible manner, it is necessary to change the position or adjust the size of all objects (images, videos, animations, etc.) of the teacher. It is possible to achieve it naturally without breaking or non-reproducible phenomena.

 The teaching material database 55 completed through such a series of processes is generated as a RealTime XML Property Information file containing the contents and the physical property information (events) stored in the teaching material database, and the teaching material data when providing services to real users. Instead of calling the contents from the server, one of the teaching databases 55 is automatically called and used by the XML file.

4 is a conceptual diagram illustrating a schematic process of creating a teaching material database in the form of an XML file according to the present invention.

Referring to FIG. 4, when the administrator (or teaching planner) registers teaching plan information to generate the teaching plan database 25, the multimedia database server 20, the license management server 40, and additionally, the voice streaming server 35 are provided. Provisional data in the form of RealTime XML Property Information file is provided to general users by prior confirmation by interworking.

3. Correction Step

The teaching plan database 55 according to the present invention suggests a method that can be utilized according to a teacher's unique characteristics, and on the premise that modifications can be made for more advanced teaching drafting and utilization, a series of steps for protecting the copyright of the author At the same time, it is to identify the unauthorized use and promote the sound use of teaching materials database.

Specifically, the curriculum amendment phase is divided into a curriculum amendment approval step and an unauthorized grasp of the curriculum.

5 is a conceptual diagram schematically illustrating a teaching modification approval step according to the present invention.

The teaching plan database 55 according to the present invention may be modified many times by another teacher, but must be approved by the author A who originally created the teaching plan database 55 before the modification.

The process of approving a draft plan is to follow up on the draft plan, find out whether the plan is corrected, request that the person (B, C) request the amendment request approval from the draft planner (A), and notify the draft planner (A) of the approval request information. It consists of the following steps: determining whether to be approved by the original drafter, determining the scope of revision, and determining whether to approve the automatic approval.

 The first author (A) has a basic copyright on his or her drafting database, and B (or, in the case of C, needs to be approved by A and B / A or B) who wants to use the drafting database. When modifying / editing / adding / relocating, A is automatically requested for approval (note, email, SMS, etc.).

At this time, it is necessary to first understand whether the teaching database has been modified (specifically, correction / deformation / position change). This is because of the integrated identification code and the individual identification code generated by the identification code generation module 100. Is possible by information.

Specifically, in the case of the individual identification code is given to the individual multimedia database 25, after modifying each individual identification code that the original teaching has been able to determine the state of correction depending on whether the teaching system 25 includes all of them. In addition, since the modification of each multimedia database 25 is also made by applying the modification approval step according to the present invention, the multimedia database 25 is approved before the approval of the teaching database 55. The subsequent individual identification code described above may be added to the original identification code to be used as a secondary work).

In addition, the position change of the individual multimedia database 25 can determine whether the change by comparing the changed coordinate value and the integrated identification code.

If the curriculum is revised through the step of identifying whether the curriculum has been modified, and the curriculum is automatically notified to the first author (A) for approval, the original author (A) may decide to approve or reject the request.

If approved, the modified history of the teaching policy database is regenerated by adding a separate individual / integrated identification code to the basic identification code for the modified teaching plan database 55 and re-registered with the license management server 40. The first author (A) is obliged to record the reason for the return.

However, if there is no response (approval / return) to the approval request even after a certain period of time, automatic approval processing is performed according to the teaching sharing principle basically pursued by the present invention.

At this time, the automatic approval decision is to be made according to the modification range of the teaching plan database 55. That is, in the case where only the change of the location of the multimedia database 25 is performed without substantial modification, the case of simply deleting one of the existing multimedia databases 25 is automatically returned. This is done through an integrated identification code.

For example, it may be set to only add one or more new multimedia databases or assign one or more events to an individual multimedia database as a requirement to satisfy the modification range.

Through this series of revision steps, the approved teaching materials database (also of course, individual multimedia databases can be established in the same way) can be established as a secondary work, and the distribution of copyright fees can be set in various ways. Distribution is possible between the copyright holder and the copyright holder of the secondary work.

In addition, in the step of identifying unauthorized use of teaching materials according to the present invention, the teaching material database produced in the present invention is basically produced in a unique extension file other than XML format when unauthorized teaching is used without permission from the original teaching author. It is possible to identify by integration and tracking of individual identification codes by running on the website operated by the system according to the system.However, as described above, when the modification of the teaching plan occurs, the creator of the teaching plan will be notified automatically. It is interpreted as not to worry.

4. Steps to Provide Training through the Instructional Database

The teaching material database 55 finally completed through the above steps may be open to the public for users who are registered as paid members, and at this time, the member may be a student who wishes to study through the teaching material, or prepare or purchase a teaching material. It may be a teacher who wishes to:

As described so far, the configuration and operation of the teaching method through the Internet and the system using the same according to the present invention have been expressed in the above description and the drawings, but this is merely described by way of example.
