Junior School Students Thermal The Former Concept And The Cause Of Formation Investigation Study

In junior middle school physics,thermal content is one of the important parts of the physics curriculum system of junior high school.In daily life,the phenomenon of thermal learning is everywhere,and students have already produced a lot of pre-thermal concepts in their minds before they study in junior high school.Some of these former concept,in line with the concept of science,can be used as the starting point of new knowledge,but some former concept are usually lack of scientific,even is wrong,it will be hampered by thermal learning play a role of junior high school.Based on Piaget's cognitive development theory,meaningful learning theory of Ausubel and constructivism theory,under the guidance of in the compulsory education of physics curriculum standard(2011 edition)"and are" compulsory education physics textbook grade eight days,"the third chapter of state changes","compulsory education physics textbook ninth grade(book one),chapter 14 internal energy in the course of" chapter 13,"as the foundation,on the basis of predecessors' research on thermal former concept design questionnaire survey index,index design according to the survey questionnaire,investigating the first former students about thermal concept,using SPSS 21.0 software for data analysis.Research has shown that the influence factors of thermal former concept formation are various,including daily life experience,students make mistakes in understanding the language of life,students existing thinking ability and the elementary school science teaching effect on the thermal former concept.Combined with the research theory and research results,targeted for thermal knowledge module three forms "material","change of state","temperature with a thermometer","molecular motion theory" and "energy" relevant teaching Suggestions are put forward.
