The Physics Curriculum Standards for Compulsory Education(2022 Edition)points out that the core competencies to be cultivated in physics curriculum mainly include physical concepts,scientific thinking,scientific inquiry,scientific attitude and responsibility.There are phenomena such as “inquiry in performance” in physics inquiry experiments in junior high school.Through reviewing relevant literature,The author finds that the front-line teachers and relevant scholars have made beneficial improvements and expansion.However there are still some problems: how to get the problem of experimental inquiry? How to design the experimental plan? How to obtain evidence? How to process and explain the experimental data? It is of great practical significance to study what design strategies physics teachers should follow when they design physics inquiry experiments in junior high school.In view of that,the research topic of this paper is determined: research on the design strategy of junior high school physics inquiry experiment,which provides feasible design strategies for front-line teachers,and expects front-line teachers to effectively carry out physics inquiry experiment teaching and better implement the core competencies.Base on relevant research conducted by domestic and foreign scholars in the field of inquiry experiments,combining with science inquiry theory,behaviorist theory,and constructivism theory,this paper conducts a discussion on the design strategies of junior high school physics inquiry experiments,analyzes the characteristics of junior high school physics inquiry experiments,and initially proposes the design strategies of junior high school physics inquiry experiments:phenomenon ‐problem strategy,thinking‐plan strategy,operation‐data strategy,method‐explanation strategy,communication‐promotion strategy.According to strategies,the author designs and practices three experiments that junior high school physics inquiry students must do-explore the characteristics of planar mirror imaging,explore the balance conditions of leverage,explore the relationship between electric current and voltage,resistance.then these three teaching practice are analyzed and evaluated.Based on the design examples,the initially proposed design strategies for middle school physics inquiry experiments were combined with teaching effectiveness to refine and deepen the understanding of the strategies,and the conclusions of the study were drawn,and the application suggestions are put forward: generally speaking,one strategy should not be used alone,but the comprehensive application of students’ learning situation and teaching environment should be considered systematically.At the same time the author explains how to use each strategy concretely.Finally,the overall research was reflected and prospected. |
