Research On Interdisciplinary Teaching Practice Of Penetrating Physics Subject Knowledge In High School Chemistr

With the progress of education and the development of society,the demand for comprehensive talents in society is increasing,and countries around the world have projected the eyes of talent training to cross-penetration teaching,focusing on cultivating students' comprehensive ability.This study sorts out the development history and research status of cross-teaching at home and abroad.Understand the current status of cross-teaching at the current stage through questionnaires and interviews.The survey results show that although teachers and students generally believe that chemistry and physics are closely related,in the actual teaching process,due to the limitation of teachers' knowledge reserves and teaching hours,cross-teaching is not ideal.Cross-teaching emphasizes the cultivation of students' comprehensive ability,and this study selects teaching practice research based on high school chemistry disciplines to carry out penetrating physics knowledge,providing an example for front-line teachers to carry out cross-teaching.By combing the knowledge points that intersect with the physics department in the compulsory part and elective part of the high school chemistry of the human-taught version,the author analyzes the connotation of the cross-teaching theory,and finally selects the "chemical reaction and energy" part,taking "chemical reaction and energy change","combustion heat energy","calculation of chemical reaction" as cases,designing ahigh school chemistry teaching design that integrates physics knowledge,and carrying out teaching practice to cultivate students' comprehensive ability.Finally,the teaching effect was evaluated through the teaching paper-and-pencil test and the teacher's interview,and the evaluation results showed that the cross-teaching effect was good,and the cross-teaching in the process of chemistry teaching could cultivate students' comprehensive ability to acertainextent?...
