High School:Physics Teachers’ Classroom Viaed Text Analysis Research

Based on physical ability theory, this study constructed the theory model of high school physics classroom video text analysis, and the video "Lenz’s law" section of the class are analyzed in the text. This research includes the following five parts:The first part discussed the background of this study, the problems we proposed and solved in the research, and elaborated the significance of this study.The second part through the literature review of the text analysis found that text analysis has been applied in every field, but these analyses are mostly stayed in the surface of the text, such as word, word analysis, and the corresponding analysis software. In addition, although the text analysis has a very wide range of applications, but has not yet been combined with a subject used in teaching. For the classroom video research literature review found that Research about classroom video limited to teachers’ professional skills or interaction between teachers and students, and rarely in combination with a subject, applied relevant theories of the discipline, to go deep into the subject within the classroom study. Therefore, this article combined the text analysis with classroom video, and did the high school physics classroom video text analysis research.The third part was the theoretical basis. The premise of analysis is revealing contradiction. The contradiction that this paper analyzed was the "power" training in the physics teaching."Intelligence, skills, and cognitive structure" theory ability includes intelligence, skills (mental skill and operation skills) and cognitive structure (knowledge and scientific method). According to the competence these elements reflected in the classroom, and how teachers should cultivate the ability elements, looking for a foothold in the classroom to cultivate ability, namely the classroom video text analysis theory model, including five dimensions:scientific method manifest education, the characteristics of physical science, teaching essence, teaching principles and teaching logic.The fourth part is to construct the theoretical model of the application of the "Lenz’s law" section of the video class were analyzed in the text. Translated the audio in video into text, and then analyzed the text about the five dimensions. Analysis result:in the case this paper selected had the only physical discipline characteristic dimensions of ability training, without the scientific method manifest education, teacher grasping the essence of this lesson was not allowed, also there was no follow certain teaching principles, and then resulting in teaching logic is not clear. So most of the physics classroom are now having no consciousness of training students’ physical ability.The fifth part was the conclusion of this study, including the conclusion of theoretical results and practical research, and according to the construction of the theoretical model of the corresponding teaching suggestions in five dimensions.
