Description

REALTIME SYSTEM FOR PROVIDING LIVE IMAGES RELATED TO ON-LINE LECTURINGS AND METHOD THEREOF}

The present invention relates to a remote lecture system and method, and more particularly, to a system and method for a lecturer to lecture a student in real time over the Internet.

Currently, middle school and high school students are educated by the teachers in charge of each subject at the official school system. However, it is also true that most students are trained by professional instructors or tutors in after-school private institutes or in their homes. Therefore, most families have a cost problem due to private education expenses.

Therefore, various methods for reducing such private education costs are currently proposed by the instructor teaching students using the Internet. Sites that provide such alternative educational services include, for example, Samsung Web School (www.samsungelectronics.com/kr/webschool), Cyber School (www.keicc.co.kr), On Study (www.onstudy.com). ) And 1318 classes (www.1318class.com).

Samsung Web School uses a CD-ROM and the Internet to teach lecturers how to lecture students. However, this method is limited in its use because it cannot be taught in real time and the cost is quite high.

Cyber school is a site that provides education programs for elementary and middle school students. However, this site is limited to individual subscribers in that it operates a cyber school in association with a school, and has the disadvantage that it cannot provide lecture service in real time like Samsung Web School.

On Study offers instructors in each subject to open their own courses and provide educational services to their members in either paid or free form. However, since the subjects of courses consist of national certification classes and foreign language classes, they are not suitable for education for middle and high school students, and cannot provide lectures in real time like other sites.

The 1318 class allows the user to download and receive video lecture data from the server, and provides the video lecture and the problem at the same time so that the user can solve the problems associated with the lecture immediately after watching the video lecture. However, the instructor cannot educate the student in real time.

In addition, there are many sites that operate remote lecture services, but there is no system for teaching students in real time.

Accordingly, an object of the present invention is to solve the problems of the conventional sites as described above.

In other words, the instructor provides students with online lecture services in real time, so that the instructor manages the students more effectively, improves the learning effect of the students, and reduces private education costs.

The real-time remote video lecture system of the present invention consists of a rear subsystem 1 and a front subsystem 2, wherein the rear subsystem 1 is a dual LAN (LAN 1 and LAN 2), a backup LAN, and each of the LANs. A score management server 3 connected to each other, a plurality of database servers 4 and 5 connected to each of the LANs, a database 6 connected to these database servers, a backup server 7 connected to a backup LAN, and the backup server A digital linear tape (DLT) 8 connected to the front subsystem 2, wherein the front subsystem 2 comprises a dual LAN (LAN 3 and LAN 4), a backup LAN, a plurality of web servers 9, 10 and 11), a WAP server 12 connected to each of the LANs, and a Web log 13 connected to each of the LANs. Each of the LANs is connected to a hub to be connected to the external Internet, and is configured to connect the front subsystem 2 and the rear subsystem 1 to each other. It is configured to not stop the service even when any hub is overloaded, and is configured to prevent the intrusion of the rear subsystem 1 from hacker intrusion by the firewall.

Hereinafter, the functions of each component will be described. LAN is for communication between each system component, and by configuring a dual LAN (LAN 1, LAN 2, LAN 3 and LAN 4) and backup LAN to prevent the system overload, to prevent interruption of service provision. The DLT 8 is a backup storage device connected to the backup server 7. The streaming server (not shown) relays the online lecture system. The web servers 9, 10, and 11 connect an external user with a home page implementing this system. The swap server 12 is a server for the user to access this website through a wireless mobile phone such as a swap phone that is currently put into practical use.

2 is a diagram briefly showing the configuration of the entire database in the system of the present invention. The database of the system (6 in FIG. 1) includes a member database 21, a community database 22, a bulletin board database 23, a library database 24, a shopping mall database 25, a lecture video database 26, and attendance. A management database 27, a simulated test result database 28, and a question bank database 29. For example, the member database 21 is composed of a student database 21-1 including information about a student, and an instructor database 21-2 including information about a teacher. Specifically, the student database 21-1 includes the student's name and ID, grade, age, one or more courses, desired and determined levels for each of the courses, desired instructor requirements, names and IDs of selected instructors, and Contains information about the address. Here, the desired instructor requirements of the student include gender, education of the instructor, lecture time, lecture progress, and the number of students. In addition, the instructor database 21-2 includes the name and ID of the instructor, the education level, the gender, the desired lecture subject, the desired and determined level for each of the desired lecture subjects, the lecture time, the current lecture progress, and the It includes name, ID, and address information. Such information becomes information necessary for automatic connection between the student and the instructor described later. The attendance management database 27 includes the information which checked the attendance of the student and the instructor at the lecture time. The question bank database 29 includes problems of each lecture subject, and is a database for comprehensively managing these problems, each of which is recorded in a manner classified into a plurality of selected units and a plurality of levels, and simulated later. Used in exams. The simulated test result database 28 includes all information related to the test results of each subject. In other words, the simulated test result database includes information about the student's test scores, grades, levels, etc. The lecture video database 26 is a database for providing students with lectures in addition to real-time lectures in the present system. That is, when a student needs a lecture from a professional lecturer in addition to the real-time lecture time, it is to provide a videotape in which the lecturer's lecture on the relevant part of the subject is recorded. Since the community database 22, the bulletin board database 23, the library database 24, and the shopping mall database 25 of the database of this system are common to a general website, the description related to this is abbreviate | omitted.

3 is a flowchart of a student's registration for a course on a home page (hereinafter, abbreviated as a home page) implementing the system of the present invention.

First, the user accesses the Internet through his computer and then accesses the home page (S301). The connected user can browse the home page regardless of whether or not they have registered. Specifically, you can watch the lecture video for a selected time from the lecture taster corner of the various contents of the home page, you can solve the problems provided by the trial tasting corner, and you can see the profile of the lecturers and teaching materials writing staff . In addition, the bulletin board provided by the community database 22 can be toured and information about various events can be introduced. In addition, various textbooks, videos, and educational game software can be purchased at the corner provided by the shopping mall database 25. Next, the user who wishes to subscribe to the home page clicks on the subscription page, and the web server checks whether the user is a member (S302). If the user is a member (YES), but proceeds to the next step, but if the non-member proceeds to the member registration step (S304), if joining as a member (S305) proceeds to the next step (S306), join as a member If you don't, you can just take a tour. The information created by the member in this step S305 is recorded in the member database 21. At the membership stage, if the member is a student, information that needs to be recorded includes the student's name and ID, grade, age, desired instructor requirements, and address. Desired instructor requirements for a student should include the instructor's education, class time, and student population. At this time, the user who wishes to register as a member can provide the information on the use method of the home page, the tuition fee per subject, and the member privilege, and preferably provide a member authentication key.

Next, in the case of a member, he selects the course he wants to take (S303). If a subject to be taken by the member is selected in this step (S303), a problem that can test the learning level for the subject is provided, and the corresponding subject level of the member is determined (S306). When the level is determined, the member's level is displayed on the terminal that the member is using for access, and the member confirms his or her level (S307).

After that, the member selects the instructor he wants to receive the lecture (S308). At this time, the member is presented with information about the instructors corresponding to the requirement based on the desired instructor requirements recorded by the member himself. As will be explained in the description of FIG. 4, the instructors are those who are qualified to teach to members of that level, that is, the instructors of that level. If the instructor is selected, it is checked whether or not to add another subject in addition to the subject (S309). If not added, the student pays the tuition fee for the course he / she is taking (S310), and if he adds the course he wants to take (YES), he returns to the course selection step (S303) and repeats the subsequent steps. Next course registration will be terminated.

In this way, the student can select the course and lecturer by themselves, the student and the lecturer are connected by the member database 21, the student can receive the real-time remote video lecture in the lecture time of the lecturer of his choice.

4 is a flowchart of a lecturer application step for a user who wishes to become a lecturer on the home page to register herself as a lecturer.

Steps S401 and S402 in FIG. 4 are the same as steps S301 and 302 in FIG. Like the student, the instructor first registers as a member. At this time, the information provided for the instructor member registration is different from the information of the student member. In other words, information that a user who wishes to become a lecturer should fill in includes a name, education, a desired lecture time, and an address. This information is created in the membership registration step (S405), and the user who has registered as a member is provided with information on how to use the system, calculation of tuition fees, teaching materials, and member benefits. A user who has not registered can only browse the home page as in the user of FIG. 3. After that, the user selects a subject he wants to lecture (S403). The courses selected here are recorded in the instructor database.

Next, when a subject is selected by the instructor member, the level test for the instructor qualification and lecture subjects is different from the level test for the student (S406). Unlike the student, the level of the instructor is required to be more carefully determined, so the level of the instructor is determined by the result of the level test and the examination by the expert on the qualification of the instructor (S407). When the level is determined, the result is stored in the instructor database (S408), and the member is notified. The notification method may be a method of displaying on a display device such as a terminal or a method of notifying the member by e-mail. (S409).

Information on the instructor selected in the above-described manner is recorded in the instructor database 21-2 of the member database 21, and then provided to the student at the time of selecting the instructor of the student as described in step S308 of FIG. do.

FIG. 5 is a view for explaining FIGS. 3 and 4 in more detail, and is a flowchart illustrating a method for automatically connecting a student and an instructor.

Steps S501 to S504 in Fig. 5 are the same as steps S301 to S306 in Fig. 3, and the level thus determined is notified to the student from the server. At this time, the information in each step is stored in the student database 21-1 of the member database 21 (S505).

In addition, steps S506 to S509 in FIG. 5 are the same as steps S401 to S408 in FIG. 4. The student and the instructor are automatically connected based on the level determined as described above.

In detail, the web server provides a plurality of information on the type of instructor desired by the student so that the student can select the desired instructor based on the information stored in the student database and the instructor database (S511). By this information, the student selects the instructor to be lectured (S512), and the result is stored in the student database 21-1 and the instructor database 21-2 of the teacher selected by the student (S513).

Preferably, the student's level may be determined as follows.

In the student level measurement, the student selects the desired level from five levels (upper, upper, middle, middle, and lower), each of which is 5 points in sequence from upper level to lower level, It is evaluated by 4, 3, 2, and 1 points. Next, three of the questions for level evaluation with the selected levels (up, middle, and bottom) stored in the question bank database 29 are randomly given to the student in multiple choice. These questions are preferably given in response to the desired level of students, and are evaluated as 3 to 0 points depending on the correct answer to each question. Next, within the range of the student's desired level, a short-answer question about the basic concept of the course is taken, where the short-answer question for level evaluation is used stored in the question bank database 29. The number of questions provided for the actual evaluation of the student is preferably four, and the score is 4 to 0 depending on the correct answer. In this way, the student's desired level (5 to 1 point), multiple choice level (3 to 0 point), and short answer level (4 to 0 point) are summed, and the sum is evaluated. As a result of the evaluation, if the combined score is 12 or more, it is preferable to classify as the upper level, the middle level when the score is 5 to 11, and the lower level when the score is 4 or less, and the level evaluation result is displayed in the student database 21-1. Stored.

Although the assessment methods described above may be used, the student may use a method such as solving a puzzle (eg, horizontal / vertical puzzle) for a concept or word for the subject, and the student's desire to learn Can promote it.

The level of the instructor also uses the above-described student level evaluation method, but it is preferable to use the instructor level evaluation problem classified and stored in the question bank database 29 as an instructor.

Although levels are determined in this manner for students and instructors at the membership registration stage, the levels determined in this way may be adjusted up or down by evaluation results for each predetermined period.

In the real-time remote video lecture system of the present invention, the student and the instructor are connected based on the level determined in the above-described manner, for example, the student at the level level can select one instructor from the group consisting of the level level instructors. At this time, the student is provided with information about the individual instructor, the information provided may include, for example, information, such as the educational background, gender, age, lecture time, physical condition of the instructor. In the enrollment phase, students may select an instructor by this method, but it is desirable to allow the student to select the instructor again after a period of time (for example, January or February). It is desirable to provide two to three minutes of video for lectures in order to effectively select a teacher. When the instructor is selected, as described above, the lecture time (day and time, etc.) is regarded as agreed with the lecture time of the selected lecturer, and the lecture is conducted at that time. The number of students for one instructor is preferably 5 or less, and information about the instructor who has reached the capacity is excluded when selecting another instructor after the member. Alternatively, based on the desired lecture time (day, time, etc.) of the student and the selected instructor, the student may be provided with information only about the instructor whose time matches, where a real-time remote video lecture is made at the matching time. You lose.

6 is a flowchart for explaining a lecture by the real-time remote video lecture system of the present invention.

At the lecture time determined in the above description of FIG. 5, the student and the instructor access the home page implementing the system of the present invention with their respective terminals (S601). Next, at the instructor selection step, the instructor selects himself, the student designates the instructor selected by him, and accesses the page of the instructor (S602). Next, the server checks whether the student and the instructor are members (S603). If the member is not a member, the student moves to step S305 of FIG. 3 and the instructor moves to step S405 of FIG. If the user is confirmed as a member, each student enters the lecture room (S604). Thereafter, the lecturer lectures using a computer equipped with a video camera and a microphone, and the student uses the system of the present invention through the server of the system of the present invention while watching and listening to the lecturer's lecture in real time by the student's own sensory organ. You can ask about the lecture (S605). At this time, the lecturer's lecture is stored in the server, the student can be provided to the student again at any time (S606). In addition, when it is difficult to lecture by video / audio and chat alone (for example, solving problems in mathematics), the lecture may be conducted using a device such as an electronic blackboard. At this time, it is preferable that a video window, a chat window, and an electronic blackboard window are simultaneously displayed on a terminal of a user (a lecturer and a student).

Fig. 7 is a flowchart showing a problem bank database creation process in the real-time remote video lecture system of the present invention.

The question bank database 29 of the present invention is prepared by a questionnaire having a predetermined qualification, and the questionnaire is composed of a predetermined number of subjects for each subject. First, the questionnaire is connected to the home page on which the system of the present invention is implemented, and the questionnaire dedicated program is accessed from the connected home page (S701). The questionnaire that accesses the exclusive program will question the question with the question-specific editor. The questionnaire member evaluates the level of each question at the upper, middle, and lower levels when the question is asked, classifies the details of each subject (eg, unit 1, unit 2, ...) and answers the question (S702). These details should be categorized into Chapters, Lessons, Lessons, and Examples. The problem thus created is stored in the question bank database 29 (S703) and is provided at the time of problem solving and / or simulation test.

FIG. 8 is a flowchart illustrating a simulation test file generation process in the real-time remote video lecture system of the present invention.

The student, who is a member, accesses the home page through the Internet (S801). Next, the student is a member to apply for a mock test (S302), the server using the student information stored in the student database 21-1 of the member database 21, to retrieve the level of the entire subject of the student ( S803), a question corresponding to the subject level of the member is requested to the question bank database (S804). As such, when a problem is requested from the server, the question bank database 29 generates a simulated test file (S805). The mock test file preferably includes a program for executing the file, a test scheduling program for selecting a desired time zone for each subject, and a program for transmitting the mock test result to the grade management server.

9 is a flowchart illustrating a student problem solving process.

When the simulated test file is generated in step S805 of FIG. 8, the student downloads the file (S901). Next, the user operates the execution program in the simulated test file (S902). When the program is operated and the problem file is opened, the student first selects the time zone for which the student wants to take the test by subject by scheduling the problem solving (S903). Next, the student solves the problem for the area for a predetermined time (for example, one hour) in the time zone selected by the student (S904). The practice test is presented in such a way that questions and answers (eg, 1, 2, 3, and 4) are displayed respectively, so that the student writes the answers to the questions on the answer (eg, clicking the correct answer number). Way). When the predetermined time elapses or when the end of the mock test is input by the student, the mock test program transmits the answer written by the student to the mock test result database 28 (S905).

Alternatively, unlike the individual practice test described above, there may be a practice test in which a plurality of personnel are connected to the same time zone to test for the same time. This practice test is preferable in that the test subject's performance can be compared with other test subjects.

FIG. 10 is a flowchart illustrating a grade processing process after completion of the process of FIG. 9.

When the transfer in step S905 of FIG. 9 is completed, the grade management server checks whether the student's answer matches the answer of the question bank database 29, and compares the evaluation result with the simulated test result database 28 and It is stored in the student database of the member database (S1001). The grade management server transmits the result to the student, that is, the student transmits the grade information so that the student can check (S1003), and a description of the wrong item, the similar problem is generated and transmitted to the student from the information in the question bank database 29. (S1004).

Specifically, after the step S1001 and before the step S1003, the simulation test result in the step S1001 is obtained by using the statistical method to rank the pools of students of the same level by using the statistical method, and the standard score. All methods of calculating the rankings in the entire pool including not only the same level but also other levels may be used (S1002). By providing such a ranking and generating a similar problem, the student can review the problem so that he or she is not wrong again and can clearly recognize why it is wrong.

Alternatively, a program in the practice test file may be used to grade the subject's score, which may require the web server to provide information about similar or correct answers related to the subject's wrong problem. This alternative can also implement the above effects.

As described above, according to the real-time online lecture system of the present invention, it is possible to solve the problems of the conventional Internet lecture system.

That is, according to the present invention, the instructor provides the online lecture service to the student in real time, the instructor can manage the student more effectively, at the same time improve the learning effect of the student, and reduce the private education costs.

Furthermore, according to the present invention, the instructor and the student are automatically connected according to their respective levels, one-to-one or one-to-many lectures can be realized within each level, and not only the student but also the instructor can be managed efficiently. Even if the number of students increases significantly, it is possible to quickly and accurately match the instructor-student connections.

In addition, according to the present invention, if the site management can be automated through the database of test questions for each of the lecture subjects, the grades of the subjects taken by the students are automatically managed by the database to improve the learning effect of the students. Can be.
