Research On Teaching Practice Of Chemistry Concept In Senior High School Based On Teaching Content Structure

The new curriculum standard points out that content structure are the key to promoting the transformation of students from "chemistry knowledge" to "chemistry core accomplishment".Content structuring is a process of cultivating corresponding core concepts based on the logical relations between knowledge and the cognitive ideas contained in subject knowledge.The concept of chemistry is the cornerstone of chemistry learning.Traditional teacher teaching and students’ recitation cannot realize the students’ understanding of its essential connotation.Taking the chemistry concept teaching of senior high school as an example,this study integrates the structure of teaching content into the chemistry concept teaching of senior high school,which has certain practical significance for the in-depth study of the structure of teaching content and the chemistry concept teaching of senior high school.This research is mainly divided into three parts.First,based on the "new college entrance examination,new curriculum standards,and new textbooks",the necessity of content structuring is analyzed,the structured literature is sorted out,the research status of structured teaching is analyzed,and its research significance is expounded.On this basis,the research content,methods,and ideas of this paper are determined.Combined with the introduction of content structure in the new curriculum standard,this paper defines related concepts and expounds on the theories involved in this research,such as cognitivism theory,constructivism theory,subject structure theory,schema theory,etc.,which provides a theoretical basis for this research.Secondly,it is to investigate the status quo of structured teaching.Questionnaires and interview Outlines are designed for students and teachers respectively,aiming at understanding the status quo of the implementation of structured teaching and the problems existing in teaching,and on this basis,a structured teaching design is designed.Based on the previous theoretical guidance and the understanding of teaching status,the design idea of chemistry concept teaching based on the structure of teaching content is put forward,which is to analyze the requirements of course standards and the structure of teaching materials,understand the learning situation,and determine the teaching objectives.Design teaching tasks through the control of core concepts and understanding ideas;Use the teaching content to design the teaching link structurally,use the schema tool representation.Finally,the teaching content of "ionic reaction" and "quantity of matter" is grasped by analyzing the course standard and teaching materials,and the idea of content-structured teaching design is applied to teaching design and teaching practice.The teaching effect is tested through test papers and interviews,and the conclusions of this research are summarized.The research shows that integrating the content structure into high school chemistry concept teaching has certain effects on the improvement of students’ learning interests and the construction of knowledge structure.
