Design And Practice Of Junior High School Chemistry Teaching Based On Deep Learning To Promote Concept Construction

With the deepening of curriculum reform,the new era puts forward new requirements for the development of students’ core literacy.Deep learning is an effective way to promote the development of students’ core literacy and realize the construction of subject concepts.Therefore,in the stage of basic education,it is of great significance to carry out teaching research based on deep learning to promote the construction of subject concepts,which is of great significance to implement the development of core literacy and enhance students’ ability to learn lifelong.This paper on the premise of researching and analyzing the literature on deep learning and concept construction.It based on constructivism,concept teaching and other theories.It takes students in two classes in the third year of a middle school in Zhangzhou City as the object.Through questionnaire survey and interview,we got different levels understanding of the present teaching situation in deep learning and concept construction.This study proposes a teaching strategy and teaching model for junior chemistry based on deep learning to promote concept construction.The unit teaching design is based on the theme of "Preliminary Exploration of micro world".We break the sequence of textbooks,reorganize and optimize the contents of it.There are 6 class hours to conduct teaching empirical research.Through the analysis and comparison of pre-test and post-test,process evaluation and post-class interviews,it is confirmed that this research is effective and feasible,and can effectively promote the real implementation of the basic concepts of the discipline.It can promote the construction of students’ basic concepts of discipline,cultivate discipline thinking,and develop core literacy.Based on the summary of teaching practice,the author concludes that in the teaching process,teachers should:（1）stimulate enthusiasm based on real situations;（2）pay attention to group cooperation and process evaluation;（3）think highly of deep learning and build subject concepts.The practical result shows that the realization of deep learning in the teaching has a certain role in promoting the construction of students’ basic concepts of chemistry.Meanwhile,it can realize the transformation of teaching mode from "knowledge-based" to "concept-based".However,due to the author’s lack of long-term front-line teaching experience and the limited number of research objects,more researchers are needed to conduct more in-depth research and optimization,promote students’ in-depth learning in teaching,cultivate and develop students’ basic concepts of disciplines,and improve the core literacy of disciplines.
