The Reflection-development Research Of Chemistry Teacher Based On Video Analysis

Self-evaluation and reflection are important guarantees for teachers’ professional development. In this paper, the main problems are:(1) let the chemistry teacher evaluate the teaching activities by video analysis;(2) make the chemistry teacher has consciousness in reflecting and develops the ability for reflecting by exploring multiple reflecting-angle;(3) the teacher designs tools for reflecting according to different teaching contents;(4) improve the teacher’s teaching ability by reflecting and correcting.This is a research on reflection-development of the chemistry teacher, the author is the research object; two first year high school classes called A, B of my own are regarded as the implement objects. The mode of this study is "practice firstly→pinpoint the problems→reflect and improve basicly→practice secondly (video)→reflect as a whole by video analysis→pinpoint the problems→reflect focusly by video analysis→improve self-evaluation means and teaching→next action......". The teaching contents are "chemical concept" and "elements and compound" of PEP compulsory1.Through the reflection practice based on video analysis, theauthor achieves obvious effects on professional development:(1)master the skill of video analysis and develop the habit ofself-evaluation;(2) have awareness of reflecting and develop theability of reflecting;(3) be affluent in the angles of reflecting anddesign the tools for reflecting;(4) enhance the teaching designlevel, and improve the teaching implement ability;(5) establish thereflecting models of different contents and develop the professionalquality and ability.On the basis of practice, this study gets the followingconclusions:(1) teaching reflection based on video playback andanalysis has been proved to be very effective in novice teacher’sself-reflection;(2) teaching reflection based on video analysis ishelpful for the chemistry teacher to have reflecting-awareness, andimprove the reflecting-ability;(3) teaching reflection based on videoanalysis can help the chemistey teacher to improve her professionalquality and ability.
