Construction Of Integratedtraining Program For Middleschool Chemistry Experimentoperation Skills

Chemistry is an natural science based on experiment,and chemical experiment operations are the basic activities for completing chemical experiments.Mastering the skills of chemical experimentation is the basis of the ability of chemical experiments,and it is one of the necessary skills for the development of all aspects of students.There are many research perspectives on the skills of chemical experiment operations,but there is a lack of systematic research on the training of experimental operation skills for students in the basic education stage.The method of literature research,interview and content analysis are used in this paper to analyze the requirements of the junior and senior high school chemistry curriculum standards and the experimental operation skills involved in most of the experiments in middle and high school curriculum.In order to help students form a complete operational skills system and strengthen students' chemistry experiment ability,an integrated training program for middle school chemistry experiment operation skills is constructed in this paper,which is expected to become an auxiliary force for students to establish a perfect chemical knowledge system.This paper consists of five parts.The first part is an introduction.The research background and significance,status,ideas and methods of chemical experiment operation skills at home and abroad are elaborated.The second part is an overview of the relevant concepts and theoretical foundations involved in the study of chemical laboratory operational skills.Concepts of skills,operational skills,experimental operational skills,and chemical experiment operational skills are defined.The third part is the analysis of the middle school chemistry experiment operation skill and the current situation of the middle school chemistry teacher training students' experimental skills.The standard requirements of the junior and senior high school chemistry curriculum and the experimental operation skills involved in most of the experiments in the junior and senior high school curriculum are analyzed.Meanwhile,in order to collect the teachers' understanding of the current chemistry experiment teaching skills,as well as suggestions and comments on building an experimental operating system,the front-line chemistry teachers in junior and senior high schools are interviewed.The fourth part is the construction of the integrated training program for middle school chemistry experiment operation skills.In the process of constructing the training program,the junior and senior high school chemical experiments involved in the curriculum standards are classified.According to the difficulty of the experimental operations involved in different types of experiments and the order of the theoretical knowledge of the corresponding experimental content in the teaching materials and the actual teaching process,the junior high school chemistry experiment is divided into three stages of training series and the senior high school chemistry experiment is divided into five stages of training series.By doing that with the purpose of gradually developing students' chemical experimental operation skills,we hope every experimental operation learning is progressive,which can make student initially understand first,imitate and practice latter,and finally use skillfully.The fifth part is the summary and outlook.The research results are summarized,and recommendations and prospects are made.
