Teaching Research On The Cultivation Of Senior High School Students’ Physical Modeling Ability Based On Exploratory Experiment

In the physics course standard,it is clearly pointed out that physical modeling ability is an important part of core literacy,and exploratory experiments are an effective way to cultivate students’ physical modeling ability,so this research will take exploratory experiments to cultivate high school students’ physical modeling ability as the research theme.Through literature research and text analysis,the concepts,components and behavioral observation indicators of physical modeling ability were sorted out,and the correlation and correlation degree between the eight mandatory exploratory experimental teaching and modeling ability of high school physics were analyzed by text analysis method.On this basis,combined with cognitive learning theory and constructivist theory,some teaching strategies are proposed on how to cultivate students’ modeling ability in inquiry-based experimental teaching.Based on this teaching strategy,two specific experiments were selected for teaching case demonstration design,and the teaching links closely related to the cultivation of students’ modeling ability were designed and analyzed.The main contents of this study are as follows:In the conceptual definition,this study mainly defines the physical modeling ability and exploratory experiment,and on the basis of the research of many researchers,the components of physical modeling ability are sorted out,and the requirements of the course standard for students’ physical modeling ability are clarified.In this study,"constructivist theory" and "cognitive discovery learning theory" are used as theoretical foundations for the cultivation strategy of physical modeling ability in exploratory experimental teaching.In the analysis of physical modeling ability of exploratory experimental teaching,this part is based on sorting out the components of physical modeling ability,sorting out and analyzing the behavior observation indicators of physical modeling ability elements in exploratory experiments,analyzing the correlation between the eight mandatory exploratory experiments and modeling ability components of high school physics course standards,selecting two typical cases as analysis demonstrations,and analyzing the frequency of modeling ability elements in these two exploratory experiments according to the behavior observation indicators of the modeling ability components.and then derive the necessary connection between them;According to the same method,the remaining six exploratory experiments were analyzed,the frequency of modeling capability elements contained in these eight exploratory experiments was calculated,and the intrinsic relationship between them was analyzed from different angles,and then it was concluded that the development of exploratory experiments could not be separated from the physical modeling capability elements.Among them,students’ analytical ability is the key ability of experiments,and teaching should pay attention to cultivating students’ ability in the link of proposing problems,formulating plans and designing experiments,and analyzing and demonstrating to improve students’ physical modeling ability;However,insufficient attention has been paid to the cultivation of physical modeling thinking ability.Based on the conclusion of the correlation analysis between inquiry experiments and modeling ability,combined with cognitive learning theory and constructivist theory,some teaching strategies of inquiry experiments to cultivate students’ modeling ability are studied.Among them,"Teaching Methods for Cultivating Physical Modeling Ability" mainly clarifies how the five physical modeling components of "analytical ability,communication and cooperation ability,motivation,self-development ability and physical model thinking ability" are cultivated in exploratory experiments.At the same time,on the basis of the teaching method of element cultivation and combined with the theory of modeling teaching,the strategy of "combining modeling teaching and exploratory experimental teaching" is proposed,which explains how to cultivate physical modeling ability in exploratory experiments.In order to clarify the applicability of teaching strategies,this study will design teaching cases according to teaching strategies for demonstration,and select "Exploring the Relationship between Acceleration and Object Force and Object Mass" and "Exploring the Relationship between Transformer Primary,Secondary Coil Voltage and Number of Turns" as examples,design the teaching process according to the teaching strategy,and indicate in the case how to cultivate students’ physical modeling ability in the exploration experimental teaching.This study analyzes the components of eight exploratory experiments and physical modeling capabilities in detail and obtains theoretical results,which provides theoretical materials for front-line teachers to understand the composition of physical modeling capabilities.According to the strategies proposed by the theoretical results,the inquiry-based teaching is designed to clarify how inquiry-based experiments cultivate students’ physical modeling ability,and provide practical reference for front-line teachers to implement teaching.
