Development And Practice Of Micro Video Resources For High School Physical Model Problem Teaching

Developing students' ability of problem solving is an important goal of high school physics teaching. Many educators devote themselves to the study of the factors which affect students' physical problem solving. They advocate that physics class should foster students' ability of physical modeling and model application to improve the students' ability of problem solving. Therefore, it is necessary to carry out physical model teaching and cultivate students' model thinking ability. Based on the theory of constructivism and the theory of modern educational technology, and combined with the unique advantages of micro video technology used in teaching, author of this paper designs the physical model teaching cases and make the micro video for auxiliary teaching high school physics model.on the theory search part, author analyzes the concepts of physics model teaching and micro video. Model teaching is supported by the theory of constructivism and micro video teaching is supported by the theory of modern educational technology. Then author analyzes the present situation of the research on micro video teaching and model teaching at home and abroad.In this paper, author designs Three phase cases of The physical model problem teaching and chooses the curve motion module test questions from the physical volume of college entrance examination as the resource of cases. And then make the micro video for class. In the link of physical model teaching design, do :(1) having a classification with physics model in a generalized way,and listing the common curve movement combination model in senior school stage, creating folder file for enumerated model.(2) Sorting out a teaching path which from college entrance examination to students ' problem-solving ability : test questions-> analysis and construct model-> model appearance-> model application->problem solving. This paper emphatically analyzes the link of model application, showing three phase cases of the physical model problem teaching: the design of the declarative knowledge (the initial acquisition of the model), the design of the procedural knowledge stage (the initial application of the model), the design of the strategic knowledge stage (automatic application of the model).In the link of micro video making, (1) This paper analyzes the advantages and feasibility of using micro video to explain physical model problems. Searching after the development principle and pattern of micro video making. This paper briefly introduces the steps of using the Apple to record the screen and making the video. Because the versionChinese of Camtasia Studio is few for Apple, it is necessary to solve the plight of many Apple users who can not make micro video. (2) Using the software like Camtasia Studio?imove?quicktime player to practice micro video cases included light rope light bar model and train the corner problem.
