| With the gradual progress of curriculum reform and the promulgation of the General High School Physics Curriculum Standards(Revised Edition 2020),the integration of modern information technology into physics teaching has become an inevitable trend,and sensor experiments are gradually introduced into the classroom as a new type of experimental approach.This study summarizes the current situation of traditional experiments and sensor experiments in the context of physics laboratory teaching today through literature analysis method,compiles the overview of domestic and international research on sensor experimental teaching,and determines the research objectives and contents;meanwhile,based on constructivist learning theory and multiple intelligence development as the theoretical basis of this study.The feasibility of optimizing the integration of traditional experiments and sensor experiments was determined after statistical analysis.The focus of this study is to analyze the current situation of the popularity and use of sensor experiments,and then to construct a case teaching process for optimizing the integration of traditional experiments and sensor experiments.The advantages and disadvantages of the 21 compulsory experiments of the high school physics textbook in the "2020 Revised Edition" are compared with each other in terms of experimental equipment,experimental process and error analysis,and the significance and principles of the optimal integration of traditional and sensor experiments are summarized.We analyzed the optimal integration of the two types of experiments in terms of experimental equipment and experimental methods,and designed two cases of integration of the experimental lessons "Investigating the relationship between acceleration and force and mass" and"Investigating the characteristics of parabolic motion" according to the optimal integration of the two aspects.Through the feedback and comparison of the teaching effect,we propose to improve the integration of traditional experiments and sensor experiments by taking "Investigating the relationship between acceleration and force and mass" as an example. |
