Research And Implementation Of Electronic Whiteboard In Real-time E-Learning

As the rapid development of computer network, distant real-time learning has become a hotspot of computer-aided education. The prerequisite of real-time teaching on the internet is online classroom system. In the system, the conventional blackboard is replaced by the electronic whiteboard, which breaks traditional teaching pattern.The electronic whiteboard makes full use of the characteristics of information-based education. It brings the informationization to classes and daily teaching activities while combing the modern teaching method and the advantages of traditional pattern. The whiteboard system can satisfy the basic needs for teachers. It's easy and convenient for the teachers to write, draw or carry out some other sort of teaching activities. The whiteboard system provides simple and effective mechanism to improve the efficiency of the process management.Through the research on modern e-learning standard and extensive investigation of whiteboard system at home and abroad, the thesis puts forward the framework of whiteboard system based on hardware equipments; besides, it proposes a solution which adopted media encoder and GDI+ painting technologies. At the same time, it details the specific solution of the two core parts of the whiteboard system, inserting scripts synchronously and whiteboard sketch. Furthermore, it takes the standardized real-time teaching system as example, integrates the e-learning system with e-learning standardization, and introduces the application of whiteboard in teacher-terminal, students-terminal and standard courseware resources.The construction of real-time teaching system based on electronic whiteboard will promote the innovation of schools significantly, and devote to improve teaching efficiency and quality, cultivate the creativity and independency of students.
