Teaching Design And Practice Of High School Chemistry Review Course Based On STSE Education Concept

It is stated in the Chemistry Curriculum Standards for General Senior High Schools(2017 edition 2020 revision)that: teachers should pay attention to the selection and organization of the content and theme of STSE in teaching,closely relate to the reality of production and life,and enable students to realize that chemistry can create more material wealth to meet people's ever-growing needs for a better life,to enable students to use their knowledge to explain and solve STSE problems.Based on the review of the status of STSE education research at home and abroad and the teaching function and characteristics of the review course,and based on the characteristics of the review class,guided by the principles of system and constructivist learning theory,this paper constructs the teaching ideas of high school chemistry review course based on the STSE education concept.The details are as follows: analyze the STSE elements in the curriculum standards and select the appropriate review topics;looking for the combination point of topic knowledge STSE and establishing the core issues of review;create a coherent STSE teaching situation and construct a knowledge network system;create meaningful learning activities based on STSE situations with growth points;selected and compiled related STSE exercises to promote knowledge,ability and accomplishment.According to the above ideas,with the “chemical reaction and the energy conversion”and “the nature of the organic compounds with ethanol” as the core to review project as an example,the teaching design of review lesson based on STSE education concept is carried out,the core idea is to raise scientific questions in STSE context to awaken students' existing knowledge,constructing knowledge network through STSE situational network,combination with meaningful learning activities,to guide students to use chemical knowledge to explain and solve problems in science and technology,social production and life,and environmental protection,and to develop scientific attitude and social responsibility literacy.The teaching design of the review course “Chemical Reactions and Energy Conversion” based on STSE education concept is implemented.Under the guidance of the integrated concept of “teaching-learning-evaluation”,This article to develop and use the activity performance evaluation and interview method to analyze the teaching effect evaluation,the final results show that it can help students realize the purpose of reviewing,it can guide students to analyze and solve chemical problems from the perspective of science,technology,environment and society,and contribute to the development of scientific attitude and core accomplishment of social responsibility.
