| Based on specific object motion situations,with the help of multiple physical thinking methods and forms,important physical conception,laws and mechanical models are established to form preliminary physical concepts,and then form a systematic theoretical system and master systematic scientific research methods.It is of great significance to the study of mechanics teaching in high school.This article summarizes its construction methods by constructing the knowledge structure system of mechanics in high school,and then more effectively guides teaching,in order to improve the teaching quality of basic education curriculum and talent training.The main research contents and results of this paper are as follows:On the basis of a brief description of the research status,theory and concept definition of the construction method of high school mechanics knowledge structure system,in order to specifically grasp the students’ knowledge and understanding of the high school mechanics knowledge structure system,the level of ability to construct the high school mechanics knowledge structure system and the use of thinking tools,a set of questionnaire to investigate the construction method of students in the high school mechanics knowledge structure system was compiled.Using SPSS software to analyze the data,it is found that there are four main problems in the construction of the high school mechanics knowledge structure system for students:the wrong understanding of the content contained in the high school mechanics knowledge structure system,poor understanding of thinking connections between physical concepts,Insufficient thinking in images,and poor use of thinking tools.Aiming at the problems of students,this article takes the linear motion project in high school mechanics as an example to carry out the practical research on the construction of a knowledge structure system.The knowledge structure system is constructed for each section,each chapter,and the whole project in the linear motion respectively.the process is analyzed in detail,and the thinking forms,thinking methods and thinking procedures involved are extracted from it.At the same time the author extracts the physical conception,core concepts,physical models,ideal processes,physical laws,etc.The "Methods for Constructing High School Mechanics Knowledge Structure System" proposed in this article contains two construction ideas,"bottom-up"and "top-down".Through teaching practice,the feasibility and effectiveness of the construction method are tested,which can provide a certain reference for education colleagues. |
