Research On The Connection Between Junior Middle School And Senior Middle School Physics Experiment Teaching

In the process of high school physics teaching,experimental teaching plays a pivotal role.In experimental teaching,the author found that the contents?skills and methods?operating habits and ideas of physics experiment acquired by senior high school students in junior high school will directly affect the physics experiment learning in senior high school.Based on the above background,this article relied on the theory of physics experiment teaching,Jerome Seymour Bruner's structure-discovery teaching theory,David Pawl Ausubel's theory of cognitive assimilation,and the theory of "recent development zone",this paper studied from the angle of the connection of physics experiment teaching in junior and senior high school.First of all,some students from S senior high school and D junior high school in Shenyang and physics teachers from some high school were selected as the main research objects.The questionnaire survey was used to investigate the current situation of junior and senior high school physics experiment teaching.There are some prominent problems in the connection process: 1)Junior high school physics teachers do not pay attention to the cultivation of students' ability to use mathematical tools;2)The experimental abilities of the students are uneven,and the experimental basis of some students needs to be strengthened;3)Physics teachers in junior and senior high schools have less opportunities to communicate with each other and have a low understanding of each other's experimental teaching;4)For the similar and even repeated experiment contents in junior and senior high schools,the teaching objectives of some physics teachers in senior high schools are not clear enough.According to the results of the investigation,and combined with the physical curriculum standards and physics textbooks of junior and senior high schools,this paper analyzed the causes of the problems in the connection of physics experiment teaching in junior and senior high schools from the differences in the difficulty of experimental teaching content,the changes in students' ability requirements,and the changes in teaching methods.(1)The differences in the difficulty of the experimental contents are mainly reflected in the changes in the structure and principle of the experimental measurement instruments,the requirements of the experimental analysis,the experimental teaching objectives,and the experimental data processing methods;(2)The changes in students' ability requirements are mainly reflected in the changes in the requirements for students' mathematics ability,thinking ability,scientific inquiry ability and operation level;(3)The changes in teaching methods are mainly reflected in the change of students from the subject of observation to the subject of operation.Finally,based on an in-depth analysis of the causes of the connection problems,aiming at the problems in the current physics experiment teaching connection,through the specific teaching cases,from the perspectives of junior high school and senior high school,the paper put forward the following suggestions for connection:(1)Junior high school teachers can use the "unexpected phenomena" in the experimental curriculum skillfully and introduce high-level knowledge in a timely and appropriate manner;Add transitional experiments in the experimental teaching to properly penetrate qualitative and semi-quantitative analysis methods.(2)Senior high school teachers can guide students experience the process of inquiry to eliminate the cognitive misunderstanding;Based on the actual situation of students' learning,find out the growth points of experimental teaching,and improve students' cognitive structure.(3)In addition,this paper also put forward some suggestions on the connection of physics experiments in junior and senior high schools from the perspectives of teachers,textbooks and schools.
