Teaching Practice Research On Deep Learning Of High School Chemistry Based On Concept Construction

"General High School Chemistry Curriculum Standards(2017 Edition)" advocates the cultivation of students’ chemistry subject concepts in the teaching process and promotes the transformation of students’ learning methods.The deep learning of high school chemistry based on concept construction starts from the perspective of concept construction and penetrates the basic concepts of chemistry in the process of deep learning.Use situational teaching and questioning to structure complex knowledge to promote students’ in-depth understanding and mastery of knowledge.Infiltrating the basic concepts of chemistry between the deep learning process of chemistry can cultivate students’ concepts and thinking in chemistry,and promote the transformation of students’ learning styles.Based on this,this thesis tries to conduct research from the perspective of the integration of concept construction and deep learning with the background of chemistry curriculum standards.With a viewing to opening up new ideas for high school chemistry teaching.This study used the literature analysis method to analyze and sort out the existing research on deep learning and concept construction,and determined the core concepts and theoretical foundations.Using the survey research method to investigate the current situation of high school chemistry concept teaching and deep learning,and determined the current situation of high school chemistry concept construction teaching and the level of students’ deep learning ability.Taked this as the starting point,the basic concepts of chemistry were integrated into the general route of deep learning;a deep learning route based on concept construction was proposed.This thesis explained the specific route.Selected the knowledge in the second section "Ion Reaction" sections of the second chapter of the compulsory high school chemistry of the People’s Education Edition for teaching case design.Two parallel classes in the first grade of a middle school in Yinchuan,Ningxia were selected for teaching practice.The experimental class adopted a concept-based deep learning route teaching,while the control class adopted traditional teaching methods.After practice,pre-assessment,classroom observation and deep learning effect questionnaires were used for qualitative evaluation.The chapter evaluation was used for quantitative evaluation.Tested the practical effect and conducted research conclusions.The research results showed that deep learning based on concept construction has a certain effect on promoting the transformation of students’ learning styles.The combination of real situations and advanced questioning deepens students’ understanding and mastery of chemistry knowledge.After students undergo deep learning based on concept construction,their enthusiasm for chemistry learning,critical thinking ability,knowledge integration and reflection ability had been improved.The above showed that the concept-based deep learning proposed in this research has practical value in high school chemistry teaching.
