Cultivation Of Hypothetical-deductive Reasoning Ability In Teaching Newton's Laws Of Motio

In the "General High School Physics Curriculum Standards(2017 Edition and 2020 Revision)" issued by the Ministry of Education,scientific reasoning is classified as one of the elements of scientific thinking.As a type of scientific reasoning ability,hypothesis-deductive reasoning ability is an indispensable key ability for students to conduct scientific inquiry and develop scientific thinking,and is of great significance for the implementation of the teaching goal of cultivating core literacy in physics.Therefore,this study aims to cultivate the hypothetical-deductive reasoning ability of high school students,and adopts appropriate teaching methods to provide reference for later teaching.This study tested the development level of scientific reasoning of first-year high school students in Beijing,analyzed its influencing factors,and proposed an optimization strategy for the teaching mode used in this study based on the test results and interviews with front-line teachers.Combined with optimization strategies,teaching design is proposed and detailed teaching case analysis is carried out.The details of this article are as follows:Chapter 2 covers basic concepts and theoretical foundations.The first is the analysis of the meaning of scientific reasoning ability,and the analysis of the theoretical basis of measurement tools;Secondly,the research status of the hypothesis-deductive reasoning ability theory mentioned in this study is explained,and it is defined,and the elements for cultivating this ability are proposed on this basis.Thirdly,the meaning of situational cognitive theory and its elements in the cultivation of hypothesis-deductive reasoning ability are discussed.Finally,the research objectives and contents,research methods and research significance are introduced..The third chapter is an analysis of the development of hypothesis-deductive reasoning ability of high school students.Firstly,the scientific reasoning ability of high school students is tested,and the influencing factors of their development level are analyzed based on the test results.Among them,the hypothesis-deductive reasoning ability dimension is the focus of analysis.Chapter 4:Research on teaching strategies for cultivating students’hypothesis-deductive reasoning.Interviews were conducted with front-line teachers,and six optimization strategies were proposed for teaching mode based on the teaching experience of front-line teachers.Chapter 5 is designed for teaching cases to cultivate students’hypothesis-deductive reasoning.In this study,three sections of "Free Fall Motion","Newton’s First Law" and "Law of Universal Gravitation" were selected for teaching design,and the teaching links were explained in detail in combination with optimization strategies.Chapter 6 is the research conclusions and outlook.Firstly,the research process of this study is summarized and the research conclusions are drawn.Secondly,according to the conclusions,the shortcomings and prospects are put forward.
