| The "Physics Curriculum Standards for Senior High Schools(2017 edition,2020 revision)" issued by the Ministry of Education proposes to cultivate students’ core literacy in physics.Physical evidence awareness has been mentioned many times in scientific inquiry and is an indispensable link."Evidence" is repeatedly mentioned in the requirements of core literacy in physics and academic quality.Therefore,cultivating high school students’ awareness of physical evidence will be so important.The analysis of the shortcomings of high school students’ evidence awareness shows that thesis analyses the issue during the training process of high school students’ evidence awareness,improves the ways and strategies of training their evidence awareness,and present the way of teaching proposal after practical teaching,in order to provide certain design ideas for cultivating students’ evidence awareness through demonstration experiments.This study uses literature research method,questionnaire method,case analysis method and teaching practice method respectively to point out the theoretical and practical significance of this study,sort out the relationship between the theoretical basis of evidence awareness and demonstration experiment,and then conducts a survey on the cultivation of students’ evidence awareness.According to the questionnaire survey of a senior high school in Mianyang and the interview of teachers,it is shows that,There are still many issues in their awareness of physical evidence.For example,they usually have a weak sense of evidence and change experimental data at will during the experiment.The kind of physical evidence you know is relatively simple;ability to collect and process evidence in various types and ways needs to be improved;Some teachers do not pay enough attention to the ability of cultivating for students’ awareness of physical evidence.Therefore,the cultivation of high school students’ physical evidence consciousness is urgent.Based on the survey results,the author put forward a teaching strategy of cultivating their awareness of evidence.On the basis of this strategy,curriculum resources are mined from textbooks,extracurricular reading materials and network platforms to enrich the types of physical evidence for high school students and establish their awareness of physical evidence.Finally,based on demonstration experiments,Thesis makes use of physics history and teaching evaluation to conduct practical research on evidence awareness of high school students and test and analyze the results.The results show that the teaching strategy combining questioning,hypothesis,verification and reflection of the whole thinking step through demonstration and experiment has an obvious positive effect on cultivating students’ high level of physical evidence awareness. |
