Research About Teacher’s Teaching Behavior Changes Under The Environment Of Electronic Dual-Whiteboard

Classroom as the focus of the research is the trend of educational research, and also the effective way to promote the professional growth of teachers. As a new type of information-based teaching environment, Pangu electronic dual-whiteboard teaching platform of National Engineering Research Center for E-Learning of Central China normal university has significant advantages of teachers organizing personalized teaching activities, building a "student-centered" classroom structure, promoting revolution and innovation of classroom teaching.Research about teacher’s teaching behavior changes under the environment of electronic dual-whiteboard helps to explore teacher’s teaching behavior changes rule, analyse the problems existing in the teachers’ teaching idea transformation, putting forward the basic strategy of teacher’s teaching behavior optimization, and then shorting the stage of exploration and adaptation of teacher’s teaching under the new environment, accelerating the informatization process of classroom teaching.Firstly, the paper summarizes the research situation of the electronic dual-whiteboard and classroom teaching behavior change, carding on the classification of the teacher’s teaching behavior, establishing the three-dimensional analysis level with classroom teaching behavior body interaction analysis, time series analysis of classroom teaching activities, teaching mode analysis as the breakthrough point. Behavior body interaction analysis emphatically discussed increase or decrease trend of an interaction between teachers and students in different stages in the classroom from the microscopic view; time series analysis of behavior activities focuses on the spread length and the effect changes of teaching activities which refers to teaching events made up with pieces of meaningful behavior from the perspective of medium; change of teaching mode is concentrated reflection of change of interaction behavior and teachers organizing the teaching activities form and macro summary of changes of teachers’ classroom teaching behavior under the environment of the electronic dual-whiteboard.Then, chosen the C teacher who is teaching under the environment of PGP electronic dual-whiteboard as a case study, the paper dynamically tracks the teacher’s classroom teaching in a semester. Through designing classroom interaction code to carry on measurement statistics of behavior ratio, found that under the environment of electronic dual-whiteboard teacher’s information interaction behavior reduce and students’ information interaction behaviors increases, teachers put the initiative of the classroom back to students; teachers’ emotional interaction behavior and students’ cognitive interaction behavior were obviously increasing, teachers’ emotional interaction behavior influence students’ cognitive interaction behavior; and teachers’cognitive interaction behaviors and students’ emotion interactive behavior does not change significantly.Through drawing sequence diagrams of teachers’ teaching activities in the environment of electronic dual-whiteboard, summarizing the changing rules of teachers organizing the teaching activities with the time, found that under the environment of electronic dual-whiteboard teaching organization form of the C teacher tend to "diversify" and "miniaturization" and activity effect remains to be strengthen; through analysis of S-T, defining the teaching mode of analysis samples, found that C teacher mainly used hybrid teaching mode during a term.On the basis of the above research, this paper discusses two-way restriction relationship of the "technology-behavior",on one hand, the electronic dual-whiteboard environment promotes the changes of teacher’s teaching behavior, on the other hand, teachers’ own quality influences further development of electronic dual-whiteboard. Finally, this paper puts forward the macro strategy of promoting teacher’s teaching behavior optimization and the micro strategies of the specific teaching activities organization under the electronic dual-whiteboard environment.Macro aspects:we should strengthen teachers’ skills training, building the teachers’ professional growth environment which is the integration of teaching-study-research, and further perfect the function of plate. Micro aspects: teachers should pay attention to the timing, the determination of theme, the guidance of the process and the deepening summary when they organize teaching activities.
