Research On The Teaching Design Of The Intersection Contents Of Physics And Chemistry In Senior Middle Schools

The promulgation of the Physics "Curriculum Standards" gives teachers more independent choice in teaching,but also puts forward higher requirements for teachers' professional ability.When explaining some complex natural phenomena or laws in teaching,it is necessary to connect with multiple disciplines.In order to help students learn physics more easily and comprehensively,it is very necessary to study the teaching design of the interdisciplinary content of high school physics and chemistry.This research adopts literature research method and case research method.It is based on learning information processing theory,discovery learning theory,learning transfer theory and multiple intelligence theory.On the basis of analyzing and combing the intersecting content of high school physics and chemistry "Curriculum Standards" and textbooks,a general idea of teaching design for the interdisciplinary content of high school physics and chemistry was formed.Based on the ideas of teaching design,the "second law of thermodynamics",The three sections of "Gravity Potential Energy" and "Electric Potential Energy" have been designed for teaching.Based on the existing high school physics teaching design evaluation table,combined with the analysis of the interdisciplinary content of physical chemistry,the "Evaluation Table of the Teaching Design of the Interdisciplinary Content of High School Physics and Chemistry" was formulated,and the table was used to evaluate the teaching design cases.Studies have shown that the "Curriculum Standards" of the two disciplines of physics and chemistry overlap in the nature of the courses,basic concepts,core literacy of the disciplines,course objectives and course content.The current two sets of physics and chemistry textbooks not only have the same knowledge of atomic structure,ideal gas state equations,thermodynamic laws,etc.,but also the same thinking methods such as energy conversion ideas,energy/charge conservation ideas,and obstacles to change,and they all convey the same knowledge.Rigorous and objective scientific attitude and social responsibility of everyone.The three teaching cases developed using the teaching design ideas of the interdisciplinary content of high school physics and chemistry have reached a good and excellent level,and have been recognized by the evaluators.Therefore,the teaching design ideas have certain validity and can be applied to actual teaching.Exploring a feasible direction to effectively deal with the problem of the intersection of physics and chemistry in high school.
