Research On The Teaching Strategy Of Cultivating The Ability Of Junior Middle School Students To Conduct Chemical Experiments

The study of chemical experiments is the basis of junior high school students' chemistry learning.In junior middle school,chemical experiment learning and chemical theory study complement each other,and together promote the development of chemistry ability of junior middle school students.The ability of chemical experiment is the core of the students' ability of chemical experiment.This paper aims at investigating the current situation of training junior middle school students' chemical experiment operation ability,aiming at the existing problems,puts forward several teaching strategies to effectively enhance students' chemical experiment operation ability,and applies practice in practical teaching.From the two aspects of theory and practice,we should cultivate junior middle school students' operation ability of chemical experiment,so as to cultivate students' operation ability of chemical experiment better.It consists of the following five parts:The first part is the introduction,introduces the research background,training of junior high school chemistry experiment skills teaching strategies of purpose and significance of the study,put forward specific ideas and methods of junior high school chemistry experiment skills teaching strategies and practice of training,and the research of the overall design.The second part is the theoretical research on the operation ability of chemical experiment of middle school students.Through literature review,the connotation of chemical experiment operation ability and the constituent elements of chemical experiment operation ability are analyzed and combed.These theories are redefined in the light of the research direction of this paper.The third part is through the investigation of the current situation of junior middle school students' chemical experiment operation ability,and interviews with front-line teachers,and uses the experimental operation ability evaluation form to evaluate the experimental operation ability of junior middle school students.The reasons for the formation of the present situation and the existing problems in the actual teaching are analyzed.The fourth part through the investigation of the present situation of junior high school chemistry experiment operation ability,to clear from the steps of the experiment ability,the use of appropriate experimental skills,experimental results or experimental data,recording experiments or data capacity,error analysis and experimental reflection ability five aspects to cultivate the students ability of chemical experiment operation teaching strategies.The fifth part is about the teaching practice of training junior middle school students' operation ability of chemical experiment,and makes a comprehensive analysis of the practical results of the experimental operation ability evaluation table.It also measures and evaluates the practical effect of training junior middle school students' operation ability of chemical experiment.
