Practical Research Of Junior Middle School Chemistry Recitation Based On Particle View Construction

Chemistry is a natural science that studies matter and its changing rules on the basis of micro-particles such as atoms and molecules.It is essential to guide students to construct a certain view of chemical particles if they want to learn chemistry well in a short period of one year in junior middle school and even let students leave chemical ideas in their minds after finishing their study.This is not only a national curriculum standard,but also an important guarantee for students to learn chemistry well,a consideration for students' long-term development.But in the junior high school chemistry review class teaching infiltration of chemical concepts research is not much,involving the cultivation of particle outlook is not.Based on this,the author tries to carry out the "practical research of junior high school chemistry review course based on the construction of particle outlook" by using the methods of literature,questionnaire,analysis and experiment,in order to promote the construction of students' particle outlook in junior high school chemistry review course and improve the review efficiency.This study will discuss from the following six aspects:The first part: elaborates the background,significance,content and research methods of the topic.The second part: Summarize the related research,including the current situation of the review of chemistry,the review of chemistry based on the construction of chemical concepts,and the teaching practice of particle concept.The third part: The content analysis of the particle outlook in the ninth grade chemistry course,including the analysis of the curriculum standard of the content of the particle outlook and the analysis of the content of the particle outlook in the textbook.Part IV: To carry out the practical research of junior high school chemistry review course based on the construction of particle outlook,including the object of study,research process,teaching design process of junior high school chemistry basic concept training,teaching design case of junior high school chemistry review course based on the construction of particle outlook and questionnaire survey.The fifth part: the analysis of research conclusions,including the analysis of the construction of students' particle outlook and the analysis of students' achievements.Part VI: Research conclusions,reflections and prospects.Through the practical research of the junior middle school chemistry review course based on the construction of particle outlook,this paper summarizes the research conclusions and makes reflection and prospects.Through this study,it is found that the junior high school chemistry recitation course based on particle outlook can effectively promote the development of students' particle outlook,but also can improve the efficiency of the recitation course.
