The Causes And Breakthrough Strategies Of Teaching Difficulties In The Principles Of Chemical Reaction In The PEP Edition

There are many difficulties in the "Principles of Chemical Reaction" of the teaching version.The breakthrough of the difficulties is conducive to cultivating students 'enthusiasm for learning chemistry.At the same time,it is also a good opportunity to exercise students' willpower,resilience,and creativity.This topic is based on certain theoretical basis to the teaching of the chemical reaction principle of today's high school the actual situation of investigation and research,to sinopec anqing city one science class as the logical analysis,research object,literature,data statistics and using the method of questionnaire,the difficulty of the principle of the high school chemistry in-depth investigation and research,to find out students are difficult to grasp the understanding,differentiation,and can't be in time to the chemical reaction principle into the existing cognitive structure of the difficulties,and then,according to the data analysis of the chemical reaction principle of students think that causes difficulty,at the same time the author also under the guidance of the theoretical knowledge with practice,in-depth analysis of grade 11 students causes the difficulty of the principle of chemical reaction.Finally,the author will be based on the investigation and analysis of results and the theoretical basis for the article put forward and the principles of chemical reaction principle difficulty breakthrough breakthrough measures.Theory to guide practice,as well as the theory and practice will be the result of the reaction in this paper,the chemical reaction principle of the difficulty of breakthrough strategies and measures are still need further perfect in practice.
