Investigation On The Concept Of Pre - Mechanics Of Junior Middle School Students And Research On Teaching Countermeasures

Basic physics concept is the foundation of physics learning, and students in the system before physical concept by perceptions of physical phenomena formed by the daily life of the former concept and the basic physical concept of students learning the immeasurable influence. Find out students’ mind that exist in the former concept, according to former concept worked out the corresponding teaching strategy is Paramount.Before this study junior middle school students selected physical and mechanical concept as the research contents, mainly on physical and mechanical the knowledge module about seven or eight grade students before the present situation of the concept of targeted research, obtained valuable research achievements of junior middle school physics teaching. On consulting a large number of literature and interview for a line of junior high school physics teacher, on the basis of established effective measurement tools, measure to students of junior middle school students in grade seven, eight, sorting out the junior middle school students before the mechanics concept of the status quo, and summarize the characteristics of errors before the concept, analysis the causes of errors before the concept, then according to these reasons make the corresponding teaching countermeasures.This study consists of five chapters, chapter 1 based on the concept of the importance of teaching and the influence of former concept to concept teaching important module in the physics mechanics working on junior high school living concept of the status quo, and several important concepts are defined.Chapter two as the study of preparation, the emphasis on the development course of domestic concept before the research concepts before and domestic research status, and according to the research status at home and abroad to find out the deficiency of the existing research. Against these deficiencies for research purposes, research methods, design measuring tool.The third chapter is according to current situation of junior middle school students mechanical error of former concept for analysis. Using measurement tools to investigate seven or eight grade student errors concepts and summarizes the status quo of the wrong before the concept of characteristics, and analyzes the causes of errors before the concept.Chapter four countermeasures formulation, for the teaching in junior middle school students physical mechanics concepts before cause different formulate corresponding teaching countermeasures.Chapter five of this research summarizes the conclusion and put forward to research prospect in the future.
