Description

Foreign language presentation guidance system and method

The present invention generally relates to the field of foreign language learning systems and methods, and more particularly, to systems and methods for teaching foreign language presentations online.

Recently, online foreign language learning systems have been actively developed and provided due to the advantage of overcoming temporal and spatial constraints, and are gradually expanding. In the past, such an online foreign language learning system was implemented by recording lectures of instructors offline to construct video learning contents, and then providing the video learning contents through a network to students who access the service server through the Internet. Has been. However, such a conventional internet learning guidance system merely provides recorded video learning contents to students, and can only perform a unilateral knowledge transfer function, thereby lowering learning efficiency. In order to overcome this problem, in Korean Patent No. 832001 registered under the name "Internet Impregnation Guidance System and its Provision Method", an instructor's additive response created by an instructor in response to a student's essay question is synchronized using a synchronization method. When reading this additive answer, if you want to check the contents of a specific part or to review / repeat the contents of a specific part, select any one of voice data, additive data, and writing data. Therefore, unselected data is synchronized and linked. The reason for adopting this technique is to provide a realistic and corrective lecture by synchronizing correction and writing and instructional voices for the answers to the essay questions written by the students, which has the advantage of bringing the lecture to life. However, this patent can help improve understanding of reading and writing in that it provides the student with essay questions and adds and corrects the student's essay content, but the technical achievements bring the lecture to life. Since the focus is on synchronizing corrections, writing, and instructional voices, students will be able to improve their listening, reading, writing, and speaking skills, which are the four essential functions of foreign language learning. It can be said that it is insufficient to be applied to a learning system that guides students to do so.

On the other hand, in Korean Patent No. 848260 registered under the name of "writing learning instruction method and system", when a learner writes and transmits writing content, an instructor based on index information that is analyzed and analyzed in advance by grammatical and structural data. The first correction information is given to the learner, and the learner is given an opportunity to correct the error by himself / herself by referring to the first correction information, and analyzes the structure, skeleton, style, and summary of the composition in advance. After providing the learner's secondary correction information based on the objectively-arranged index information to the learner, the present invention provides a method and system for writing learning that provides an evaluation score and a total rating on the learner's writing. However, in this technique, since the learner writes and transmits the writing information, the correction information is given to the learner. Can not have advantages. In addition, this technique is mainly focused on writing and correcting instruction, and it is not enough to make the foreign language presentation smooth by improving students' listening, reading, writing, and speaking skills in one learning system. Has disadvantages.

Moreover, in conducting instruction on foreign language writing or presentation through the online learning system, there is a problem that if the instructor allocates a lot of time to the guidance of one student, the profitability is reduced. Therefore, there is a need to provide a learning system that reduces the time spent by the instructor while reducing the quality of the instruction.

In addition, the recent evaluation of foreign language ability is changing from a simple written test that can be easily solved only by mastering foreign language writing. There is no online education system that effectively improves this.

Therefore, the problem to be solved by the present invention is that the corrected grammar and pronunciation errors that students usually make in writing or speaking are provided to the student without the instructor's intervention, thereby reducing the time spent by the instructor. To provide a system and method for presenting a foreign language presentation.

Another object of the present invention is to provide a foreign language presentation guidance system and method capable of comprehensively improving the ability to listen, read, write, and speak a foreign language in one system.

A foreign language presentation teaching system of the present invention for achieving the above object comprises: a lecturer terminal comprising a first voice generator, a first image generator, and a lecturer map data generator; A student terminal including a second voice generator and a presentation creator; Subject content provision module that provides students with content on presentation subjects, automatic grammar correction module that corrects grammatical errors in presentation sentences written by students, and instructor's correction of student's final presentation. A presentation map module including an instructor map data providing module for providing a; Includes a subject content DB that stores content information related to the presentation subject, a basic grammar DB that stores grammar information for correcting grammatical errors without instructor intervention, and a learning management DB that stores information related to the student's final presentation and instructor guidance data. A system DB; A service server that provides the student terminal with automatic correction without the instructor's intervention on the presentation sentences written by the student by applying the grammar automatic correction module and the basic grammar DB, and communicates information between the student terminal and the teacher terminal. Wow; It characterized in that it comprises a network connecting the student terminal, the instructor terminal and the service server with each other.

In addition, the presentation teaching method using the foreign language presentation guidance system comprises the steps of: (a) providing a presentation topic content from the service server to the student terminal; (b) prepare a presentation sentence in the student terminal and transmit the presentation sentence to the service server, and send the correction without the instructor's intervention on basic grammar from the service server to the student terminal to apply the correction while the student writes the presentation sentence. Completing the writing of the presentation sentence; (c) recording a voice comment in which the student comments on the intention of writing a presentation sentence of the student terminal; (d) transmitting the completed presentation sentence and recorded voice comment to the service server; (e) reviewing the instructor terminal by receiving the completed presentation sentence and recorded voice comment; (f) generating, at the instructor terminal, map data including guide sentence correction, voice recording, and video of the instructor's review result in step (e), and transmitting it to the service server; (g) requesting the service server from the student terminal and receiving and confirming the map data.

According to the present invention, it is possible to comprehensively improve the listening, reading, writing, and speaking skills of foreign languages in one system, thereby improving the learning effect. This can be reduced by reclamation, thereby increasing the profitability of companies providing this foreign language presentation guidance system and method.

In addition, simple repetitive mistakes that occur during the production of presentation sentences or pronunciation of sentences are automatically corrected by the system and corrected by the instructor for the logic or ideas of the text, thereby reducing the time burden on the instructor. do.

In addition, by sending a voice comment that the student comments on the intention of writing the presentation sentence to the instructor, the instructor can grasp the student's intention to write the sentence and provide effective presentation instruction.

The following examples are only presented to understand the content of the present invention, and those skilled in the art will be capable of many modifications within the technical spirit of the present invention. Therefore, the scope of the present invention should not be construed as limited to these examples.

1 is a schematic configuration diagram of a foreign language presentation guidance system according to an embodiment of the present invention, Figure 2 is a flow chart for explaining the overall presentation instruction method using a foreign language presentation guidance system according to an embodiment of the present invention. 1 and 2, a foreign language presentation guidance system according to an embodiment of the present invention includes a system DB 110, a presentation guidance module 120, a service server 130, a network 140, and a student terminal 150. ), Including the instructor terminal 160. The presentation instruction module 120 may be installed only in the service server 130 as various programs related to the operation of the system, and some or all of them may be downloaded and installed in the student terminal 150 or the instructor terminal 160. As it is, basically, the subject content providing module 122, which provides the content for the presentation topic to the student through the student terminal 150, grammar for correcting the grammar error for the presentation sentences written by the student without the instructor's intervention The automatic calibration module 124 includes an instructor guidance data providing module 128 that provides instructor correction for the student's final presentation. The presentation guidance module 120 may further include a pronunciation automatic correction module 126 and a voice recognition module 129 in addition thereto. The system DB 110 basically includes a topic content DB 116 storing content information related to a presentation topic, a basic grammar DB 112 storing grammar information for correcting grammatical errors without an instructor's intervention, and a student's final presentation and lecturer. It includes a learning management DB 118 that stores information related to the map data. The pronunciation DB 114 is further included in the system DB 110 in response to the presentation instruction module 120 further including a pronunciation automatic correction module 126 and a voice recognition module 129. Since the system implements online education, the learning management DB 118 may also include DB information including student information registered as a member of the online education, class lecturer information, and class schedule. The instructor terminal 160 includes a first voice generator 162 and a first image generator 164 using a device such as a microphone and a webcam (or a camcorder), and a related voice / image generating program, respectively. The instructor guidance data creation unit 166 is a program in which the instructor guidance data providing module 128 is downloaded and installed in the instructor terminal 160, and the instructor guidance data creation unit 166 includes the first voice generation unit 162 and the first. 1 Using the image generator 164, the final presentation contents of the student, for example, the instructor guidance data for the student's presentation image, voice or presentation sentence, is generated as a voice or image file. The student terminal 150 basically includes a second voice generator 154 and a presentation creator 156, and optionally, a second image generator 152. As such, the reason why the second image generator 152 is selectively included in the student terminal 150 is that if it is difficult to generate an image file according to the specification of the student terminal 150 held by the student, it is inevitably necessary. This is because the presentation contents can be generated only by a pronunciation file to receive presentation training. The service server 130 basically provides a function of providing the student terminal 150 with the automatic correction without the instructor's intervention on the presentation sentence written by the student by applying the grammar automatic correction module 124 and the basic grammar DB 112. Perform. In addition, it performs a function that allows the mutual information transfer between the student terminal 150 and the instructor terminal 160. On the other hand, the network 140 serves to connect the student terminal 150, the instructor terminal 160 and the service server 130 with each other.

FIG. 2 illustrates a method of teaching a foreign language presentation to a student using a foreign language presentation teaching system having the configuration as shown in FIG. 1. Referring to FIG. 2, when a student connects to a service server 130 through a network 140 using a student terminal 150 such as a computer, and requests a learning instruction (step S200), a subject in the service server 130 is provided. The content providing module 122 provides a topic content list (step S202). The subject content is a description file of the subject of the presentation sentence to be written by the student. The subject content is stored in the subject content DB 116 in the system DB 110 as an image file, a voice file, a video file, and the like. In step S203, the specific topic content is selected (S203), and the selected topic content is provided in the student terminal 150 by the download or streaming method (S204). FIG. 3 is a view showing an example of contents displayed on a display of a student terminal or an instructor terminal of a foreign language presentation guidance system according to an embodiment of the present invention. Referring to FIG. 3, a video display unit is displayed on the upper left of the topic content display unit 302. It can be seen that 304 is provided at the bottom with a guide image display unit 306. The subject content list display unit 308 of the content display unit 302 lists the titles of the subject contents. When the user selects the subject contents by clicking on the subject contents, the subject contents are output from the student terminal 150 as an image, a voice, or a video. In FIG. 3, the guide image display unit 306 at the bottom of the topic content display unit 302 includes contents for guiding a writing direction of a presentation sentence to be written by a student. For example, as illustrated in FIG. 3, a key concept, a mission, a point to point, and a mind map may be included as shown in FIG. 3. When the corresponding button is clicked, the corresponding content is provided to the guide image display unit 306 at the bottom of the content display unit 302. The guide content displayed by the guide image display unit 306 at the bottom of the topic content display unit 302 can be created / modified by an instructor or a student. In this case, the save button 307 on the mind map button is displayed. Press () to store the guide content created / modified via the network 140 and the service server 130 in the subject content DB 116. If this guide is written by the instructor, it will be the instructor telling the student how to write the presentation. If the guide is written by the student, it will be a summary of the student's intention to write the presentation.

When the subject content is provided to the student terminal 150 as described above, the student creates a presentation sentence using the presentation creator 156 based on this (step S206). The presentation sentence is displayed on the presentation sentence display unit 310 during the writing process, the presentation sentence during the writing process is transmitted to the service server 130 through the network 140 (step S208), the service server 130 grammar automatic correction module In operation 124, the presentation sentence prepared by the student is compared with the basic grammar data (step S216), and the corrected content of the grammar error is provided to the presentation sentence display unit 310 without the instructor's intervention (step S218). The basic grammar data is stored in the basic grammar DB 112 in the system DB 110 to automatically point out simple grammatical errors, such as tense match errors, single / plural match errors, typos, and typographical errors, of the presentation sentences being written by the student. It is used to display on the presentation sentence display unit 310 with a speech bubble or a punctuation symbol. After the student makes a correct presentation sentence by correcting a simple error, the student completes and saves the presentation sentence by pressing a save button in the presentation sentence display 310 of FIG. 3 (S220). As such, the process of automatically correcting the grammar of the presentation sentence is selectively and repeatedly performed while the student terminal 150 and the service server 130 continuously communicate through the network 140. In this way, the instructor can spend time instructing the teacher to point out and correct formal and simple grammatical errors. Thus, the system and method of the present invention has the advantage that it is possible to secure more instructor guidance time.

When the presentation sentence is completed through the step S220, the student makes a pronunciation file for his presentation sentence using the second voice generation unit 154 included in the student terminal 150, and to the service server 130 Transmit (step S222). Referring to FIG. 3, while the second voice generator 154 including a microphone and a recording program is operated to make a pronunciation file, the recording button 316 is pressed while recording is completed, the button “Submit Your Speaking”. Press 318 to upload the created pronunciation file to the learning management DB (118). The pronunciation file of the student is applied to the pronunciation automatic correction module 126 to generate a pronunciation correction file and then stores the pronunciation correction file in the learning management DB 118 in the system DB 110. This process is not also performed by the instructor's intervention, but after the student's pronunciation is recognized by the voice recognition module 129, the recognized pronunciation is compared to the pronunciation of the word which shows a significant difference compared to the pronunciation data in the pronunciation DB 114. Regarding the error, it is a process of generating a pronunciation correction file by collecting the correct pronunciation data (S224). The generated pronunciation file is displayed as a speaking list 312 on the display of the student terminal 150 by the pronunciation automatic correction module 126 in the presentation instruction module 120, and the student clicks to request transmission of the pronunciation file. In this case, the student can check the correct pronunciation through the sound reproduced from the pronunciation file (step S226). The speaking list 312 also lists up the map data by the voice recording file of the instructor.

As described above, the student pronounces the presentation sentence in the student terminal 150 and transmits it to the service server 130, and describes the process of automatically correcting his / her pronunciation by the pronunciation correction file, but this may be selectively included in the present invention. If the presentation sentence correction is completed (step S220), the automatic pronunciation correction process (steps S222 to S226) is omitted and the final presentation sentence pronunciation file is generated (step S228), and the student of the presentation sentence Create a voice comment file recording a voice comment commenting the intention (step S230), and a video of the user's presentation using the second image generator 152 including a recording program and a device such as a webcam or a camcorder. Create a file (step S231), and finally the presentation sentence / voice comment / presentation sentence pronunciation file or Through a video file services server 130 may be uploaded to the learning management DB (118) (S232 step). Uploading the presentation sentence is performed by pressing the "Submit Your writing" button in the presentation sentence display unit 310. The uploaded student's presentation sentences are displayed in a writing list 314, which lists not only the student's uploaded presentation sentences, but also the presentation sentences that the instructor reviewed and revised later.

On the other hand, since the entirety of the student terminal 150 may not include the second image generating unit 152, step S231 of generating a presentation image as a moving image file may be selectively performed. Accordingly, it can be seen that FIG. 3 shows only storing and uploading a presentation sentence / voice comment / presentation sentence pronunciation file. Generating the presentation image as a moving image file may be performed by pressing a recording button (not shown) instead of the recording button 316 while operating the second image generating unit 152 including a recording program and a device such as a webcam or a camcorder. In this way, the generated video file is clicked on the "Submit Your Presentation" button (not shown) instead of the "Submit Your Speaking" button 318. In this case, the wave waveform display unit 320 used to generate the voice comment / presentation sentence pronunciation file may be replaced with an image display unit (not shown). Since a program used for generating and uploading a voice comment / presentation sentence pronunciation file as described above or for generating and uploading a presentation video file can be used as a module, a separate description thereof will be omitted.

The presentation sentence / voice comment / presentation sentence pronunciation file or video file uploaded as described above is stored in the learning management DB 118 (step S234).

The instructor receives the student's presentation sentence / voice comment / presentation sentence pronunciation file or video file stored in the learning management DB 118 (step S236), and examines this to create guide data (step S238). The map data includes the instructor's modifications, voice recordings, and videos on the presentation sentences that the student finally made and uploaded. This includes the first image generator 162 and the first voice generator included in the teacher terminal 160. 164 and the instructor guidance data creating unit 166.

After the instructor creates the map data, the instructor terminal 160 transmits the map data (step S240) and stores it in the learning management DB 118 (step S242).

The instructor's guidance data stored in the learning management DB 118 is transmitted to the student terminal 150 at the request of the student (step S242), and the student receives and reproduces the instructor's instructional contents for the presentation online. . The instructor's instructional data can be downloaded as a text file in the case of presentation sentences, and audio files or video files can be clipped using the recording or recording program functions, respectively, so that only the desired part can be selected. ) Can be stored. In this case, since the student does not have to check all the contents of the instructor from the beginning, the student can repeat the desired part later.

Meanwhile, although the contents displayed on the display of the student terminal and the instructor terminal are almost similar to each other as shown in FIG. 3, the implementation of the presentation sentence, pronunciation, and image writing tool is implemented in the student terminal 150 in relation to the system of the present invention. For this reason, the student terminal 150 was expressed as including the presentation writing unit 156, and because the instructor terminal 160 is a writing tool based on presentation sentences, pronunciation, image correction, and intellectual instructor terminal (160). ) Is represented as including the instructor guidance data creation unit 166.

According to the present invention as described above, it is possible to comprehensively improve the listening, reading, writing, and speaking ability of a foreign language within the foreign language presentation guidance system, thereby improving the learning effect, and the instructor is not involved in the automatic grammar and pronunciation correction. Learning efficiency increases.

In addition, by sending a voice comment, presentation pronunciation, or video that the student commented on the intention of writing a presentation sentence to the instructor, the instructor can grasp the student's intention to write the sentence and smoothly teach foreign language pronunciation and presentation behavior. can do.
