Practical Research On Structured Chemistry Teaching In High School

Structured teaching refers to connecting the elements in the teaching materials in a way that is consistent with the logic of the system,rationally organizing the teaching content,making the teaching content a substructure of the subject knowledge structure,and then helping students internalize the knowledge structure and form a cognitive structure through reasonable teaching.the process of.Hierarchical structure is a strategy that both helps memorize and solve problems.Applying the ISM model to analyze the structure of new textbooks to get directed hierarchy diagrams can help teachers and students discover the correlation between structure,learning structure,and learning knowledge,and can effectively improve students.It is considered that the knowledge of chemistry is complex,the correlation is poor,and it is difficult to form a systematic cognitive structure.This research is a structured teaching practice research aimed at the knowledge structure in textbooks and problems encountered in teaching.It explores effective approaches and strategies for structured teaching in high school chemistry,and proposes a set of suitable structured teaching design templates.First,determine the unit teaching goals based on the curriculum standards,academic situation and teaching conditions;second,apply the ISM method to analyze the structure of the textbook,scientifically grasp the chemical knowledge structure presented in the textbook,and obtain a hierarchical directed graph;third,based on the hierarchical directed Figures carry out structured instructional design.Fourth,conduct structured teaching practice and explore the effectiveness of structured instruction.Finally,test the teaching effect and give formative instructional evaluation.The main conclusion of the thesis is that using the ISM model to analyze the structure of textbooks is more helpful for teachers to see the "whole picture of knowledge" and facilitate the development of structured teaching.The development of structured teaching in chemistry can effectively reduce the degree of class differentiation and help Form a structured cognition for students and develop thinking in chemistry.
