Research On Teaching Design And Practice Of High School Chemistry Inquiry Experiment Under The Concept Of Key Competence

The proposal of key competence promotion of a new round of curriculum reform,a series of changes have taken place in high school chemistry curriculum.The curriculum standard of high school chemistry(2017 Edition)clearly puts forward the curriculum standard of subject core literacy and introduces the curriculum objectives based on core literacy.Therefore,teachers should pay attention to the cultivation of students’ subject core literacy in the teaching process.Inquiry experiment teaching is an important part of high school chemistry experiment teaching system,how to carry out reasonable teaching design and practice of high school chemistry inquiry experiment under the concept of chemistry core literacy is very important.By adopting various research methods such as literature analysis method,questionnaire survey method,interview method and educational experiment method,the teaching design and practice of exploratory experiments of high school chemistry based on core literacy are studied.By referring to relevant literature,this paper summarizes the current situation of core literacy and exploratory experimental teaching at home and abroad.Through the method of questionnaire survey and interview,the present situation of high school chemistry exploratory experiment teaching was investigated and analyzed,to understand the problems existing in the current high school chemistry exploratory experiment teaching.By analyzing the existing problems and in combination with core literacy requirement and explore the basic process of experiment,the high school chemistry zetetic experiment teaching design,the design of the “experimental study on decentralized lines and their classification”,“sodium carbonate and sodium bicarbonate thermal stability experiments”,“concentrated sulfuric acid and dilute sulphuric acid identification experiment”,“county water pollution the zetetic experiment” and “fruit battery” five teaching cases,and the exploratory experiment education in the teaching practice to carry out the practice research.Through SPSS and other analysis software,the paper analyzes the implementation effect of inquiry experiment teaching in the form of examination results,questionnaire survey and experimental report analysis,compares the results,question answering situation,learning interest,scientific inquiry ability,core literacy level of the experimental class and the control class,and analyzes the experimental report of the experimental class,so as to demonstrate the teaching effect of inquiry experiment teaching.Through the research,it is found that carrying out exploratory experimental teaching is helpful to stimulate students’ interest in learning,improve students’ academic performance,strengthen students’ scientific inquiry ability to ask questions and conduct experiments,improve students’ core knowledge,core ability,core attitude and core concept of chemistry,and finally achieve the development of students’ core literacy.
