Research On The Evaluation Of High School Students’ Physical Experiment Ability

Physics is a subject based on experiment,which is of great significance to the development of students’ thinking and the cultivation of problem-solving ability.This study mainly discusses the evaluation of senior high school students’ physical experiment ability.The full text mainly includes the following four parts:Firstly,the connotation and structure of physical experiment ability are analyzed.Based on the existing research on the structure and evaluation of physical experiment capability,the concepts of physical experiment,experimental process and experimental ability are defined.Through the basic element analysis method,the physical experiment ability is analyzed into seven first-class indexes,including: experimental understanding capability,operational capability of the experiment,experimental data processing capability,experimental error analysis capability,experimental conclusion drawing capability,experimental evaluation and improvement capability,design capability of the experimental protocol,and several corresponding second-class indexes are classified.Combined with the suggestions of experts and teachers,this paper constructs the evaluation system of senior high school students’ physical experiment capability,which lays a foundation for the preparation and evaluation of follow-up ability evaluation papers.Secondly,compile the evaluation tool of experimental ability.In order to ensure the objectivity and operability of the evaluation,this study compiled a paper and pen evaluation volume for the first time based on the ability evaluation system,combined with the suggestions of expert teachers,the evaluation paper is optimized.Then,around the physical experiment ability evaluation volume,130 high school students were evaluated.SPSS software is used to statistically analyze the overall situation of experimental ability,the relationship between various elements,the correlation between physics academic achievement and ability,and the correlation between gender and ability,and the following results are obtained:(1)The content validity coefficient is used to detect that the evaluation paper has good reliability and validity.The evaluation paper basically measures only one element in the structure of physical experiment ability.Generally speaking,the quality of the test paper of senior high school students’ physical experiment ability is good.(2)The results show that the overall level of senior high school students’ physical experiment ability is poor,and the physical experiment ability needs to be further strengthened.Students perform well in the basic experimental process and operation,the evaluation and improvement of physical experiments,but poor in the independent design scheme of experiments.Compared with prototype physics experiment and transfer physics experiment,it is found that students perform better in the former.Through the scoring rate of each structure of physical experiment capability,it is found that there are great differences between different elements of students’ physical experiment capability.(3)There are significant differences between physics academic achievement and physics experiment ability(r=0.507,p<0.01);There is no significant difference between gender and physical experiment ability(t=0.603,p>0.05).Finally,the conclusion of this study is made.Combined with the existing conclusions on the evaluation of physical experiment ability,this paper discusses the development level of physical experiment ability of senior high school students.According to the current situation of ability development,some teaching suggestions for cultivating physical experiment ability are put forward.At the same time,the shortcomings of this research and the direction of further research are summarized.
