Research On The Development And Application Of Microlesson In Junior Middle School Chemical Acid And Alkali And Salt Module

This paper on the basis of relevant theoretical research, in Ningxia Yinchuan third implementation of micro lesson to rely on, with the method of literature review, case analysis, interviews and survey methods, micro course of development and application of the process do comprehensive study, demonstrates the micro lesson on the interest of students and teachers’ professional growth positive impact, in order to micro research on the development and application of the course as a little humble.At the beginning, the paper mainly states the background, the significance of the research, the object, the content, the object, the method and the method of the research. The second part. Firstly, it concludes and summarizes some foreign for micro class discussion, and stated the each do what kinds of research, then introduces the domestic micro research status, compared with the Hu Tiesheng and Li Yuping two of micro class description. Finally, the paper summarizes the micro class definition, from foreign to domestic, from the beginning to now, micro class definition in the continuous micro variable. The third part to teach version of ninth grade chemistry the unit topic 2 the acid and alkali neutralization reaction, for example first fragment in the design of the micro class, finally will be integrated into the classroom teaching design, and traditional teaching implementation to carry on the contrast, analysis of the investigation results. In the fourth part, for teachers to design the questionnaire, and interviews, found that which problems, and carries on the analysis, finally is the statements of some of the conclusions obtained in this paper, points out the limitations and research in the future can be improved.
