高中物理新课标指出物理核心素养是学生在接受物理教育过程中逐步形成的适应个人终身发展和社会发展需要的关键能力和必备品格，是学生科学素养的重要构成。为了落实新课标的要求，本文开展基于核心素养的高中物理演示实验教学策略研究。

在文献调研的基础上，本文通过问卷调查，了解当前高中物理教师和学生对演示实验态度以及演示实验开展的现状。并对高中阶段的物理演示实验进行了总结和改进。在此基础上，选择“演示-观察-解释-归纳”、“演绎-演示-观察-检验”和“预测-观察-解释-检验”三种教学策略在相应的演示实验中进行教学实践，并对三种教学策略进行了相应的教学评价。

对“演示-观察-解释-归纳”教学策略进行了课前和课后测试，并对物理学科核心素养的四个方面进行了前后测的得分比较，并对测试成绩进行了分析和总结；在“演绎-演示-观察-检验”和“预测-观察-解释-检验”教学策略中，对学生进行了演示实验对于培养学生的物理学科核心素养的课后问卷调查，并对调查结果进行了分析，研究结果表明演示实验教学策略的应用，可以充分发挥演示实验在发展学生物理核心素养中的作用。

   本文通过对学生和一线教师的问卷调查和访谈，提出系统的演示实验教学策略并将其应用与一线教学。通过分析高中物理课堂中的几个实际案例，进行效果分析，并于有经验的教师进行交流探讨。一线教师通过上课的实际课堂效果以及课后测试的成绩，切身的体会到演示实验的优点并对演示实验教学策略提出改进和总结。通过理论研究和实践，希望能为一线教师的演示实验教学提供有益的参考。

The new curriculum standard of high school physics points out that the core quality of physics is the key ability and necessary character formed gradually in the process of students receiving physics education to meet the needs of personal lifelong development and social development, and is an important component of students' scientific quality. In order to implement the requirements of the new curriculum standards, this paper carries out the research on the teaching strategy of high school physics demonstration experiment based on core literacy.

On the basis of literature research, this paper investigates the attitude of physics teachers and students towards demonstration experiment and the status quo of demonstration experiment development through questionnaire survey. The physics demonstration experiment in senior high school is summarized and improved. On this basis, three teaching strategies of "demonstration-observation-explanation-induction", "deduction-demonstration-observation-test" and "prediction-observation-explanation-test" are selected to carry out teaching practice in the corresponding demonstration experiment, and a series of evaluations are carried out on the three teaching strategies.

The teaching strategy of "demonstration-observation-explanation-induction" is tested before and after class, and the scores of the four aspects of the core literacy of physics are compared before and after the test, and the test results are analyzed and summarized. In the teaching strategies of "deduction-demonstration-observation-test" and "prediction-observation-interpretion-test", a questionnaire survey was conducted on the effect of demonstration experiment on the cultivation of students' core literacy in physics, and the survey results were analyzed. The research results showed that the application of demonstration experiment teaching strategy, It can give full play to the role of demonstration experiment in developing students' core physical literacy.

The advantage of this paper is that, through the questionnaire survey and interview of students and teachers, the author puts forward a systematic demonstration experiment teaching strategy and applies it to front-line teaching. Through the analysis of several practical cases in high school physics class, the effect analysis is carried out, and the exchange of experienced teachers is discussed. Through the actual classroom results and after-class test results, front-line teachers personally understand the advantages of demonstration experiments and put forward improvement and summary of demonstration experiment teaching strategies. Through theoretical research and practice, it is hoped to provide useful reference for the demonstration experiment teaching of front-line teachers.
