Practice Research Of "Preview Draft Of Experiment" In High School Physics Experimental Teaching

Physics experiment is the basis of physics.Preparation let students to master the basic study methods of experiment,cultivate students' ability of autonomous learning.This paper studies prepare draft in the high school physics experiment,and puts forward some beneficial Suggestions for the improvement of the experiment teaching effect.Physics experiment preview did not get enough attention practical teaching in the high school.In the actual situation,there are some problems such as the blindness of preview,the content of preview is uncertain,Preview without guidance,Preview without inspection,Preview without evaluation.It is necessary to discuss the design and practice of experiment preview.It is hoped that this article will provide a reference for the improvement of experiment preparatory activities.This thesis is based theoretically on constructionist theory,the theory of autonomous learning and cognitive learning theory.The paper design the teaching process of Physical experiment preparation,and put forward experimental preview version.Preview draft mainly includes 5 parts: preview target,the emphasis and difficulties of the preview,preview method,preview process,the doubt of preview.The experiment preview draft is divided into demonstration experiment preview draft and grouping experiment preview draft.At the same time,The paper points out that the experiment preview methods,classification principles and methods of the experiment preview draft.In this paper,Combined with a variety of preparation methods that is to design preview version.Experiment preview draft design and classification is the highlight of this article.This paper points out that preparation evaluate and examine the way,and through the task driven studying mode let students to complete preview.Finally,validation experiment prepare draft,exploration experiment prepare draft,measurement experiment prepare draft analysis prepare draft design and practice.The research object is the two Parallel classes(the experimental classes and the comparative class).This paper mainly studies: First of all,this paper examines two dimensions of the horizontal and vertical,SPSS software was used to analyze the differences in experimental subject scores,the final exam scores and unit test score;Next,The former and the latter two dimensions carry out questionnaire,and to analyze the changes of the students' learning attitude,the experimental skills and autonomous learning ability before and after the preview.The results showed that: as the probability of independent sample t-test student achievement is less than 0.05,which shows that experimental preview version can improve the students' academic performance.The results of the survey show that physics preview draft improve the students' physics learning interest,the experimental skills,autonomous learning ability,and the effectiveness of classroom teaching.
