Research On The Teaching Strategy Of Chemistry Experiment In Junior High School

The innovation and development of the country cannot be separated from the training of new talents.Education is the main way of talent training.In recent years,the country has been making innovative attempts to reform the education system.With the continuous development of the economy and society,the requirements of the society for compound high-quality talents are more and more strict,which also puts forward new requirements for the development of education in different degrees.Among them,experiment is an important part of chemistry,chemistry is a natural science based on experiment,the formation and development of chemical science can not be separated from experiment.It is an effective way to promote the development of quality education in the new era.Experimental teaching of chemistry enables students to experience "learning by doing".By guiding students to conduct experimental operations with experimental instruments,drugs and steps provided,it can help students understand theoretical knowledge and improve their hands-on and practical ability,which is the main driving force and basic factor for their vigorous development and progress.While the new curriculum standards for middle and high schools are more comprehensive and reasonable in structure and richer and more perfect in content,they also put forward more specific and comprehensive requirements for chemical experiment teaching in middle and high schools.How to reasonably and effectively connect the two stages of chemical experiment teaching in middle and high schools has again become a focus topic.In this paper,we study the strategies of linking chemistry experiment in junior and senior high schools.Firstly,it conducts research and analysis at home and abroad,and summarizes and expounds researches on cohesion education,chemical experiment development,chemistry teaching cohesion,textbook cohesion,experimental teaching cohesion and so on.Secondly,the paper makes a theoretical analysis of the topic,including the definition of "inductive chemistry teaching","chemistry experiment teaching" and "cohesive teaching",and the theoretical basis of "cognitive structure transfer theory","proximal development zone theory","meaningful learning theory" and "learning progression theory".Then,it analyzes the theory of chemistry experiment teaching in junior high school and senior high school.Taking the connection of chemistry experiment in junior high school and senior high school as the starting point,it conducts a questionnaire survey on the four groups of students and teachers in junior high school and senior high school respectively,so as to analyze the causes of the problems in the connection of chemistry experiment teaching in junior high school and senior high school.It mainly includes four aspects: junior high school students’ lack of cognition of chemical experiments,junior high school teachers’ weak awareness of chemical experiments for knowledge expansion,senior high school students’ lack of methods for experimental learning,and senior high school teachers’ lack of bridging education.Finally,it puts forward the teaching strategy and case analysis of "chemical experiment" in junior high school.In order to raise the attention of junior high school experimental teaching and promote the smooth development of junior high school chemistry experimental linking teaching.
