Analysis Of The Difficulties In The Teaching Of "Movement And Force" In Junior Middle School Physics And The Corresponding Strategies

Physics is a science to study the laws of nature and material structure,which occupies a higher position in the middle school discipline.However,after middle school students learn mechanics,they find that "force" has become a "tiger" in their physics learning,and the teaching and research of mechanics in middle school has also become the daily routine of the majority of teachers.In the face of so many students with learning difficulties,how to help them solve the learning difficulties of "force" is a problem that many teachers,students and parents are thinking about.The author uses literature analysis to determine the core content of learning mechanics is "the relationship between movement and force".The author takes the eighth-grade students as the research object,carries on the questionnaire to the students,the interview;Observe teachers' classroom teaching,analyze and study teaching cases,and interview experienced teaching experts.Summing up the teaching difficulties related to "movement and force" and conducting a detailed dissection of the teaching difficulties.The specific research contents are as follows:(1)Introduce the background of the topic selection,summarize and analyze the current situation of the research content,and explain the research content,significance of the topic selection and research methods.Constructivism theory,cognitive development theory,meaningful learning theory as the theoretical guidance,conducive to the orderly development of this study.(2)analysis of junior middle school physics course standard,the high school physics curriculum standard of "motion and force" to the teaching requirements of the related content,and the "o 'clock" "Shanghai cantonese version" of the two different versions of the textbook "motion and force" related content has carried on the comparison and analysis,put forward some knowledge on the sort of existed irrationality,content arrangement of "motion and force" are put forward reasonable advice.(3)Through the questionnaire analysis of students and teachers,the teaching difficulties and causes of "movement and strength" are determined,and the students' cognitive level is not high,and there is "instilling" teaching method in teachers' teaching;It is proposed that the teaching level of teachers is an important factor to break through the teaching difficulties.It also points out that the teaching needs to pay attention to the cohesion of the content before and after the teaching,strengthen the knowledge repeatedly,and guide the students to improve their thinking to break through the difficult problems in the teaching of "movement and force".Finally,the author summarizes the full text,and puts forward some suggestions for junior high school physics teaching,and reflects on the shortcomings of the research and the expectation of future physics teaching and research career.
