Interactive teaching system and method of touch type mobile terminal

Abstract

The invention discloses an interactive teaching system and method of a touch type mobile terminal. Touch track or handwriting dot matrix data generated from a teacher terminal and student terminals are transmitted to a classroom computer through socket communication, the track or handwriting dot matrix data are recovered through the teacher computer and redrawn to handwriting images to be presented on a screen of the teacher computer, accordingly, students can see blackboard-writing made by the teacher on a projector, problem answering writing content of the students can be taken on the projector in class, the storage quantity of handwriting dot matrix data is small, the handwriting dot matrix data are convenient to transmit, a classroom memoir mode, a PPT playing and blackboard-writing interactive teaching mode, a teacher-student interactive teaching mode, a student-student interactive teaching mode and a group discussion teaching mode are also provided, frequent data exchange among the student terminals is avoided, data loads needing to be transmitted through a wireless local area network are minimized, and the system and method are novel in concept and ingenious in implementation and have good application prospects.

Description

technical field [0001] The invention relates to an interactive teaching system and method for a touch-type mobile terminal, belonging to the technical field of intelligent teaching. Background technique [0002] The entry of mobile terminals represented by tablet computers into the school teaching environment is a development trend of information technology entering education and teaching. In the traditional teaching environment, only the teacher can operate a classroom PC to teach the content of the classroom. Apart from watching the projector screen, the students do not have a terminal device in their hands to interact with the teacher. Classroom interaction is an important part of the class, including the interaction between teachers and students such as question and answer feedback, interaction between students and group discussions, and collaborative learning. Each student has a tablet computer as a student terminal to enter the classroom teaching, allowing teachers Li...

AI Technical Summary

Problems solved by technology

[0004] 1) Existing technical solutions often use classroom PCs or laptops with Windows system as teacher terminals when implementing classroom teaching interaction. The biggest problem with this solution is that teachers are fixed on the podium when operating computers such as playing PPT, and blackboard writing is still Blackboards and chalks have to be used separately, which makes teaching interactive not very good; and under the existing scheme, because the three elements of class teaching: PPT playback, blackboard writing, and lecture voice are separated, it is impossible for the teacher terminal to pass through Screen recording to realize the real recording of classroom teaching;

[0005] 2) In the existing solution, if a tablet computer is used as the teacher terminal, because the most common tablet computer belongs to the Android system or the iOS system, it cannot be compatible with daily teaching software or teaching resources such as PPT, geometric sketchpad, simulation software, or other multimedia Courseware, etc. Most of the teaching software or teaching resources can only run under the Windows operating system, and cannot be used normally on the tablet teacher terminal;

[0006] 3) There are often 40-50 student machines or more in a class. In order to obtain classroom teaching interaction information in a timely manner, such as checking the answers of all students, or teachers making comments and comments on students' handwritten answers, it is often necessary to quickly To switch and transfer the screen of the student computer, the image of the student terminal is currently transmitted by means of screenshots. In the wireless LAN environment, the communication data load is relatively large, and the system cannot complete the processing in a short time, which affects the rhythm of class;

[0008] Based on the above problems, at present, there is no feasible technical solution that can meet the needs of fast, real-time and efficient teaching
