| In the new version of elective 4 chemical reaction principle of PEP,sets a variety of columns.There are 4 experimental types.Such as scientific inquiry,practical activities,family small experimental.The use of textbooks in the experimental column for chemical teaching,the purpose is to comprehensively improve the ability of students to explore science experiments,practical application of ability to stimulate students’ awareness of innovative disciplines,the development of students’ scientific literacy.How to rationally and effectively use the experimental columns,and according to the actual situation of teaching,students’ cognitive characteristics of the relevant experimental columns for appropriate integration and improvement,better flexible use of textbooks in the experimental columns,practice " teaching materials."This study focuses on the use of experimental columns in the chemistry teaching of high school chemistry,is made up of five parts:The first,introduces the background,main content,significance,research ideas and methods of this research.The second,combing the new version of elective 4 chemical reaction principle experimental column of the theoretical basis.Including:the definition of the core concept;experimental column content;features;role and teaching functions.The third,access to a large number of literature,sort out the foreign,domestic textbooks on the use of experimental columns of the status quo,results,etc.,for the implementation of this study provides valuable advice.The fourth part,after questionnaires,and teacher interviews,analysis the use of experimental column of elective 4 chemical reaction principle of PEP.Found that the existence of the problems,as: students less hands-on experiment opportunities;the teaching way of experimental column is single;the design of experimental activities,improvement and study is less.Analysis of the causes of the problems.The paper puts forward the teaching suggestions of using the textbook experimental column: changing the teaching idea of the chemistry experiment,strengthening the teacher’s chemistry experiment skill;exploring the effective method of chemistry experiment teaching,improving the teachers’ instruction skill;strengthening the teachers’ research consciousness and becoming the "research type" teacher.The fifth part,due to the proposed teaching recommendations,designing the teaching case and practice research.In the teaching design,sets up a teaching reflection.It is the situation creation,experimental improvement,design intent that fully demonstrated in teaching reflection of teaching design.According to the students’ experimental ability evaluation and chemical performance of the former test,measured and post-test results of this practice to make a test to obtain the results of this study.The results of teaching practice show that the teaching of the experimental column can improve the scientific literacy of students’ practical ability,and can also improve the students’ interest in learning chemistry,enhance the students’ learning consciousness and improve the students’ chemistry achievement. |
