As communication technology continues to evolve, on-line lectures that deliver learning contents non-face-to-face through a communication network such as the Internet are becoming popular instead of conventional face-to-face off-line lectures. Online lectures do not require lecturers and learners to be in the same place at the same time, and learner has the advantage that they can take the contents of learning at their own convenience.

In the online lecture, the learner does not know the instructor's lecture ability or lecture contents beforehand, so it is difficult to judge whether the lecture is appropriate for the lecture. Given the fact that students must pay tuition in advance to listen to most online lectures, it can be a burden to learners if they do not know the lecturer's abilities or the quality of lecture contents.

Of course, the learner can decide whether or not to take the lecture by referring to lecture evaluation from another learner who has taken an online lecture that he intends to take on a web page of a server providing lecture contents. However, the evaluation of lectures from other proactive learners about online lectures is often formal. Therefore, it does not really help the learners who want to take the online course. Also, lecturers are also less likely to know precisely whether there is a problem or defect in the lecture they teach because there is little evaluation of the lecture. Therefore, although the lecture has some problems, the problem can not be solved, and it becomes difficult to provide contents of high quality lecture.

It is an object of the present invention to provide an on-line lecture system having objective lecture evaluation means and a method of providing an on-line lecture service using the on-line lecture system.

By way of example, the main categories of lecture selection can be classified into Engineering, Commerce, Natural Science, University Mathematics, Major Math, etc., and subcategories appropriate to each main category may be displayed. For example, if you select engineering category as the main category among the lecture courses, you will be provided with a rough lecture on circuit theory, electronic circuit, electromagnetism, computer structure, dynamics, statics and hydrodynamics as subcategories (lecture, tuition, , Available period, etc.) are displayed. If necessary, they can be divided into basic courses, core courses, detailed courses, short courses, and integration courses among the same subjects so that the learner can select appropriate lectures.

The lecture management module 320 controls and manages the playback of lecture contents transmitted to the learner terminal 200, the uploading and downloading of data related to the lecture contents, and the questions and answers related to the lecture contents. 3, the lecture management module 320 may be comprised of a lecture selector 322, a lecture regenerator 324 and optionally a question / answer manager 326. [

The lecture selecting unit 322 determines whether the lecture the learner intends to take is a lecture indicating whether the lecture is a lecture in which a predetermined fee has been paid. Alternatively, when the learner accesses the lecture contents providing server 300 by using the learner terminal 200 and logs in, the learner can display the lectures that the learner can take in the learner terminal 200 separately, It is possible to give an indication that it is possible. In this case, you may be able to indicate the remaining period for taking the lecture if necessary.

The lecture playback unit 324 transmits the content related to the lecture selected by the lecture selecting unit 322 to the learner terminal 200 in a streaming manner. That is, the lecture playback unit 324 reproduces a data stream related to the content of the lecture selected by the learner terminal among the lecture contents stored in the lecture DB 344, and provides the data stream to the learner terminal 200. If necessary, the user can control not only the data stream of the contents of the lecture reproduced through the lecture reproducing unit 324 but also the lecture terminal 200 through fast forward, rewind, pause, stop, . ≪ / RTI >

The question / answer management unit 326 correlates the question history transmitted from the learner terminal 200 and the response details transmitted from the lecture terminal, not shown, with the lecture contents in association with the lecture contents transmitted to the learner terminal 200 . At this time, regarding the question sent from the learner terminal 200, an answer to the question selected by the lecturer through the lecturer terminal may be implemented so as to be associated with the selected question.

The tuition payment module 330 performs the payment process of the tuition fee for the lecture selected by the learner using the learner terminal 200. [ For example, the tuition may be differentiated depending on the number of lectures for each lecture, whether it is a basic course, a core course, a detailed course, and the like. 100 days, 150 days, 200 days, etc.).

Meanwhile, the DB module 340 stores and manages information related to lecture contents, learner information, and lecture information transmitted to the learner terminal 200 through the lecture contents providing server 300. 3, in the exemplary embodiment, the DB module 340 can be divided into a lecture evaluation DB 342, a lecture DB 344, a learner DB 346, and a lecture DB (not shown).

For example, the lecture evaluation DB 342 stores the lecture evaluation contents transmitted by the learner who took the content of the lecture through the learner terminal 200. [ In the exemplary embodiment, the lecture evaluation DB 342 can also store the lecture evaluation analysis result provided from the lecture evaluation analysis unit 440 of the administrator terminal 400 described above. At this time, the lecture evaluation DB 342 may be stored in association with the learner information that created the evaluation of the specific lecture and the content of the specific lecture.

The lecture DB 344 stores lecture subjects, lecture contents, and the like as information related to lecture contents. The learner DB 346 stores the learner's personal information such as the learner's name, learner's ID and password in the lecture contents providing server 300, learner's terminal information such as the learner's terminal number capable of receiving the short message, . 4, the lecture DB may include personal information of a lecturer such as the lecturer's name, history, lecture in charge, lecture person ID and password in the lecture contents providing server 300, , Lecturer terminal information such as a lecture terminal number capable of receiving a short message, and the like.

At this time, the lecture DB 344 is associated with the lecture evaluation DB 342, the learner DB 346 and the lecture DB (not shown). Therefore, the lecture DB 340 can be implemented so as to be interlocked with lecture attendance information on lecture contents, lecturer's terminal information, learner information on lecture contents, learner's terminal information, and lecture evaluation information provided from the learner terminal 200 . For example, information such as the total attendance period of a learner taking a specific lecture and the remaining attendance period can be linked.

In addition, in the lecture DB 344, a question history transmitted from the learner terminal 200 and an answer sent from the lecturer terminal 400 can be stored in association with the contents of a specific lecture. In this case, the learner information and the learner's terminal information having raised the question may be separately stored, and when the answer is completed, the lecturer may be notified that the answer has been sent to the learner terminal 200 that raised the question. In particular, with respect to a large number of question information transmitted from and stored in the learner terminal 200, the question information selected by the lecturer and the answer information of the selected question can be stored and managed through the manager terminal 400 have.

The lecture evaluation module 350 constituting the lecture contents providing server 300 according to the present invention presents the lecture evaluation transmitted from the learner terminal 200 to the administrator terminal 400 and transmits the lecture received from the administrator terminal 400 And to provide a predetermined incentive to the learner terminal 200 based on the evaluation analysis result. As shown in FIG. 3, the lecture evaluation module 350 can be divided into a lecture evaluation management section 352 and an incentive supply section 354.

After taking lecture contents providing server 300 by using learner terminal 200, lecture evaluation is created using learner terminal 200 and transmitted. The transmitted lecture evaluation history is stored in the lecture evaluation DB 342. The lecture evaluation management unit 352 can present the newly stored lecture evaluation history to the administrator terminal 400. [ The lecture evaluation analysis result performed by the learner evaluation and analysis unit 440 of the administrator terminal 400 is transmitted to the lecture contents providing server 300. The lecture evaluation analysis result is stored in the lecture evaluation DB 342.

Particularly, in the case where the learner who provided the lecture evaluation to the lecture contents providing server 300 is the learner who took the lecture and / or the lecture evaluation data prepared and stored in association with the lecture evaluation transmitted, or The lecture evaluation management section 352 can judge whether or not it is similar based on the learner information and the lecture evaluation information stored in the database module 340. [

On the other hand, the incentive provider 354 can provide an appropriate incentive to the learner terminal 200 based on the information of the learner who has created the lecture evaluation based on the lecture evaluation analysis result stored in the lecture evaluation DB 342. [

According to the exemplary embodiment, the incentive provider 354 transmits a mobile cultural gift certificate in the form of a gift card to the learner terminal 200, a discount ticket for the lecture contents provided by the lecture contents providing server 300, Such as an extension of the length of the course.

As described above, the learner evaluation and analysis unit 440 of the administrator terminal 400 can transmit the lecture evaluation analysis result differentiated according to the size of the converted lecture text file, for example, to the lecture contents providing server 300 . In response, the incentive provider 354 can provide differentiated incentives to the learner terminal. For example, the learner terminal 200 of the learner analyzed by the 'lecture' lecture evaluation in the lecture evaluation and analysis unit 440 receives a mobile cultural gift certificate worth 5,000 won, a 5% tuition discount voucher, and / It can be provided as an incentive. On the other hand, as a learner's terminal 200 analyzed by the evaluation of the 'best' lecture, a mobile cultural gift certificate worth 20,000 won, a discount coupon of 20% and / or a 10-day extension period can be provided as an incentive.

Alternatively, any one of the incentives provided to the learner terminal 200 of the learner analyzed as the 'best' lecture evaluation may be differentiated from the incentives provided to the learner terminal 200 of the learner analyzed as the 'excellent' lecture evaluation . For example, an incentive can be provided to a learner's terminal 200 of a learner analyzed by evaluation of a 'best' lecture, a mobile cultural gift certificate worth KRW 30,000, a discount voucher of 10%, and / or a 5-day extension ticket.

As described above, according to the present invention, no incentives are provided to the learner who has prepared the formal lecture evaluation, but a predetermined incentive is provided to the learner who has made the lecture evaluation with good care. Therefore, the learner who has taken the contents of the specific lecture will send the lecture evaluation to the lecture contents providing server. Particularly, an excellent lecture evaluation history is posted on a web page of a company that operates the lecture contents providing server 300.

Therefore, the learners who want to take the lecture in the future can objectively judge whether the lecture they want to take is appropriate based on the evaluation of the lecture. The lecturer can access the lecture contents providing server 300 by using an administrator terminal (not shown), and can know the evaluation history of the lecture which is prepared with good quality. Based on this, the lecturer complements the problems or deficiencies of the lecture contents that the lecturer himself / herself has not known before, so that the lecture contents of better quality can be provided to the learner in the future.

The lecturer provides the lecture contents providing server with personal information (name, address, history, lecture) and terminal information (lecturer terminal number) using the lecturer terminal, and the lecture contents providing server inputs The lecturer person information and lecturer terminal information are stored. The lecturer can register an ID and a password for identifying each lecturer to the lecture contents providing server using the lecturer terminal. Alternatively, the administrator of the company that operates the lecture content providing server may assign IDs and passwords according to the rules set in advance to the respective lecturers. In an alternative embodiment, an administrator of a company that operates a lecture content providing server inputs history of a lecturer notified offline from a lecturer, personal information, terminal information, etc. using an administrator terminal and stores the information in a lecture contents providing server It will be possible.

The learner uses the learner terminal to acquire the learner's personal information (name, address) and the terminal information (learner terminal number), etc. in order to transmit and play the online lecture contents provided through the lecture contents providing server And registers information for identifying a learner such as a member ID and a password (S415).

Subsequently, a lecture to be taken is selected by referring to a web page or the like displayed on the learner terminal through the lecture contents providing server (S420). In the exemplary embodiment, the lecture information and the lectures subject to the lecturer are displayed in a list form on the web page operated by the lecture contents providing server. By way of example, the main categories of lecture selection can be classified into Engineering, Commerce, Natural Science, University Mathematics, Major Math, etc., and subcategories appropriate to each main category may be displayed.

For example, if you select engineering category as the main category among the lecture courses, you will be provided with a rough lecture on circuit theory, electronic circuit, electromagnetism, computer structure, dynamics, statics and hydrodynamics as subcategories (lecture, tuition, , Available period, etc.) are displayed. If necessary, they can be divided into basic courses, core courses, detailed courses, short courses, and integration courses among the same subjects so that the learner can select appropriate lectures.

In this case, it is desirable to design the learner to design the progress of the learner by specifying the total number of lectures and the possible lecture periods together with each lecture course. When the learner selects a course to be taken, the lecture contents providing server displays an input window for payment of the tuition related to the lecture of the lecture to the learner terminal. When the learner selects an appropriate payment means such as a bank transfer or a credit card for paying the tuition using the learner terminal, the lecture contents providing server proceeds electronic payment processing for the tuition fee (S425). When the payment of the tuition is completed, the learner information may be stored in association with the lecture content information. The learner selects the lecture subject to be paid using the learner terminal, and requests the lecture contents to be provided (S430).

At this time, if necessary, it may be displayed so that the lecture portion of the learner can be distinguished from the lecture portion of the same lecture. Preferably, the learner indicates the remaining period of the entire period during which the lecturer can receive the contents of the lecture (for example, 30 days if 60 days have elapsed since the lecture fee payable for 90 days) The learner will be able to induce the learner to plan the lecture.

In this manner, the lecture contents are transmitted to the learner terminal in a streaming manner by selection and request by the learner terminal (S435). At this time, besides transmitting the lecture contents, the lecture contents providing server can be implemented so that data such as a lecture problem, an exercise question, an explanation, and a correct answer can be displayed on a web page and provided to the learner terminal . In addition, an application such as a video player for playing back lecture contents, or an application capable of reading out an issue or the like can be displayed on a web page, and the learner can be guided to download the application using the learner terminal.

The learner who has taken all the lecture contents for which the tuition has been paid inputs the lecture evaluation history related to the lecture contents using the learner terminal and transmits it to the lecture contents providing server (S440A). The lecture contents providing server stores the lecture contents in association with the learner information and the lecture contents information in connection with the lecture evaluation history, and transmits the lecture evaluation history data to the administrator terminal (S440B).

The administrator terminal analyzes the presented lecture according to a predetermined criterion (S445), generates the analysis result, and transmits the lecture evaluation analysis result to the lecture contents providing server (S450). In an exemplary embodiment, the administrator terminal converts the evaluation history of the lectures presented through the lecture contents providing server from the learner terminal into a text file, analyzes the lecture evaluation history based on the size of the converted text file, To the lecture contents providing server. Preferably, the administrator terminal can generate a differentiated lecture evaluation analysis result according to the size of the converted text file, and transmit the evaluation result to the lecture contents providing server.

The lecture contents providing server can provide the learner terminal with a predetermined incentive that can be selected by the learner based on the learner evaluation analysis result transmitted from the administrator terminal. In order to do this, the lecture contents providing server notifies the learner analysis result to the learner terminal analyzed by the excellent lecture evaluation and requests to select a predetermined incentive (S455). Illustratively, the incentive that can be provided from the lecture content providing server to the learner terminal may be a cultural gift certificate, a tuition discount ticket, and a lecture period extension ticket. When the learner selects a predetermined incentive using the learner terminal (S460), the content providing server provides the learner terminal with the incentive selected by the learner terminal (S465).

As described above, the administrator terminal generates, for example, 'excellent' lecture evaluation analysis result and 'best' lecture evaluation analysis result as a result of the evaluation analysis of the differentiated lecture based on the size of the text file in which the lecture evaluation history is converted, Likewise, evaluation results of other lectures can be transmitted to the lecture contents providing server. When the lecture contents providing server provides the incentive to the learner terminal that has created the lecture evaluation analyzed as having been prepared with goodness, the incentive differentiated according to the differentiated lecture evaluation analysis result can be provided. For example, a mobile cultural gift certificate corresponding to different amounts of the learner terminal derived from the evaluation result of the 'excellent' lecture and a learner terminal derived the evaluation result of the 'best' lecture, a discount ticket having a different discount rate, You will be able to provide an extension of the course length.

Alternatively, any one of the incentives provided to the learner terminal 200 of the learner analyzed as the 'best' lecture evaluation may be differentiated from the incentives provided to the learner terminal 200 of the learner analyzed as the 'excellent' lecture evaluation . For example, the learner terminal with the evaluation result of the 'excellent' lecture and the learner terminal with the evaluation result of the 'best' lecture provide the discount ticket with the same discount rate and the extension period with the same extension period, The learner terminal for which the evaluation result of the "best" lecture is derived may be provided with a mobile cultural gift certificate equivalent to another amount.

As described above, since the online lecture contents providing method according to the present invention can induce the evaluation of lecture, it can greatly help the learner who intends to take the lecture in the future. In addition, lecturers will be able to provide quality lecture contents by complementing problems based on evaluation of lectures.

Although the present invention has been described above based on the exemplary embodiments of the present invention, the present invention is not limited to the contents described in the foregoing embodiments. On the contrary, those skilled in the art will readily appreciate that many modifications and changes may be made without departing from the spirit and scope of the present invention as defined by the appended claims. It will be apparent, however, that such modifications and changes are all within the scope of the present invention.
