High School Chemistry Experiment Design Based On The Concept Of Resource Recycle

On the basis of analyzing the literature,the principles and methods of constructing a comprehensive chemical experiment embodying the concept of resource recycling are proposed,and the important experiments of high school chemistry are selected for reconstruction.The redesigned comprehensive experiment will be closer to the chemical“new lesson” requirements and sustainability requirements.And broke through the traditional chemistry experiment teaching mode,through the students' operation experiments to cultivate students' active thinking and the ability to actively explore.Let students actively take the theoretical knowledge of chemistry and construct a network of chemical knowledge in an active learning atmosphere.The understanding of chemical knowledge is more systematic and the sense of innovation is enhanced.This study first analyzes the status quo of related research,and finds that the combination of resource recycling and experiment is widely used in university chemistry experiments.There are very few articles on applying resource recycling concepts in high school chemistry experiments.Then on the basis of theoretical research,determine the research process and research methods,analyze the content and objectives of high school chemistry experiments,and propose a comprehensive experimental design model for constructing the resource cycle concept.In the comprehensive experimental design section of highschool chemistry based on the concept of resource recycling,Iron and iron compound experiments,sodium and aluminum properties experiments,chlorine and chlorine compound experiments,sulfur and sulfur compound experiments,nitric acid and nitrogen oxide properties experiments,ammonia and ammonium salt properties experiments,ethanol,acetic acid and the nature of ethyl acetate as well as some of the key experiments of high school chemistry,was designed,and the“Resource Recycle Concept High School Chemistry Experiment Collection” covering the seven chapters of high school chemistry was written,which provided both the principle basis and the specific practical operations.Through the questionnaire survey and on-site interviews,the survey data collection,analysis and interview analysis were carried out on the application effect of the experimental set,and “Resource Recycle Concept High School Chemistry Experiment Collection” was used to conduct preliminary evaluation of teaching practice and application.The results show that the comprehensive experiment based on resource recycling not only helps students improve their comprehensive ability,but also helps students understand the systematic nature of chemical knowledge,and it also embodies the concept of resource recycling,in order to provide relevant support to subsequent researchers.
