Research On Digital Experimental Teaching Strategy Of High School Physics Based On Core Literacy

Since the 21st century,digital instruments have gradually come into sight with the rapid development of science and technology,thus information technology has become an important teaching tool for physics learning.Meanwhile,in pace with the teaching reform,our country has made schemes on how to improve students’ personal development and how to cultivate students’ necessary characters and key abilities to meet the needs of social development.As far as physics teaching is concerned,the original three-dimensional goal has been readjusted,reformed and refined,and finally turned to the core literacy of physics.Physics is an experiment-based subject,and the cultivation of core literacy is deeply connected with the physical experiments.As a new teaching form,physical digital experiment not only enriches the experimental teaching methods,but also has an important influence on the students’ understanding of physical concepts,the exercise of scientific thinking,the improvement of scientific inquiry ability,and the cultivation of scientific responsibility.In 2017,the Physics Curriculum Standards for Ordinary High Schools clearly proposed to "actively explore the deep integration of information technology and physics teaching" and "study the teaching methods of digital experiment system and promote the modernization of teaching approaches",which further illustrates the importance of digital experiment in high school physics experiment teaching.However,there is concern for the current situation in high school physics experiment teaching,which is mainly caused from the low comprehension of digital experiments and the low ability of digital experiment teaching.Therefore,the certain practical needs motivate the author to carry out research on the teaching strategies of high school physics digital experiment under the background of the core literacy.In the first part of this thesis,the previous research findings of digital experiments by domestic and foreign experts are sorted out,and the concept,pros and cons of physical digital experiments are clarified.The efforts are intended to build a solid foundation of the theoretical basis.In order to understand the current state of application and influencing factors of high school physics digital experiment,a comprehensive survey through questionnaires and teacher interviews is conducted.Through the investigation,it is found that even though physics digital experiments in high school can arouse students’ interest in learning,but it is not taken seriously by schools and teachers.In these circumstances,the reasons for the worrying situation of application are carefully investigated.Based on the conclusions of the survey,some teaching strategies focusing on the teaching principles and the characteristics of digital experiment are put forward in order to provide some reference for the digital experiment teaching in high school.The specific strategies contain four parts:constructing students’ physical concept by giving full play to the advantages of digital experiment,promoting students’ scientific thinking by paying full attention to the process of digital experiment,improving students’scientific inquiry ability by using digital experimental resources rationally,and cultivating students’ rigor attitude and scientific responsibility by understanding correctly the relationship between digital experiment and STSE（Society,Technology,Science and Environment）.Finally,two cases,"The law of parabolic motion" and "Experiment:exploring the relationship between acceleration and force and quality",are presented.And relevant teaching design and teaching practice are carried out to verify the feasibility of the digital experimental teaching strategy proposed in this study,which ultimately achieves the purpose of improving students’ physical core literacy.
