The Study Of High School Chemistry Textbook "Practice" Teaching Validity

"Practical activities" is one of the columns set in the "Experimental Textbook Chemistry for Ordinary High School Curriculum Standards".Tianjin Normal High School Uses Textbooks Required 1,Required 2,Elective 4,and Elective 5.The four books contain 23 "Practical Activities".Columns,these "practice activities" are presented to students in the form of practical problems.The purpose is to allow students to use the knowledge they have learned as a basis to solve practical problems,and to use the methods of mutual collaboration among students to sublimate book knowledge.In the end,the purpose of solving problems is to improve the sense of accomplishment and ability.China's "Outline for Curriculum Reform in Basic Education(Trial)" clearly states that "from primary school to high school,we must set up comprehensive practical activities and take compulsory courses,emphasize students' practice,enhance their awareness of inquiry and innovation,and cultivate students' sense of social responsibility." There are many articles in the new curriculum reform,but there are few columns concerning "practical activities".Related articles also only briefly describe the"Practical Activities" section and their importance statement,and use and design of"practical activities".The article on the effectiveness of implementation is basically blank.In order to make teachers use textbooks more rationally and improve classroom efficiency,it is of practical significance to study the design and effectiveness of "practical activities".This article mainly studies from the following sections:The first part:expounded the background of the topic of practical activity teaching,the research status at home and abroad,the purpose and significance of the research,and the content and methods of the study.The second part:expounded the concept and characteristics of practical activities,summed up the meaning and organization of chemical practical activities teaching,and finally explained the theoretical basis of the teaching practice of chemical practical activities.The third part:the effectiveness of the implementation of "practical activities",the establishment of evaluation standards for the implementation of effectiveness,a one-year experiment in the control class and experimental class,enumeration of experimental cases to demonstrate,design a complete practical activity instructional design,and The evaluation was conducted before,during and after the implementation.The fourth part:According to the teacher-student survey questionnaire and the results of the teacher interviews,analyze the implementation effect of "practice activities" and summarize the suggestions and strategies for strengthening the teaching of high school chemistry practice activities.Finally,combined with the teaching experience and the research process of this topic,summed up the results obtained in the course of the study,existing problems and solutions and suggestions.
