Design And Practice Of Middle School Chemistry Teaching Based On "Homogeneity Of Class"

The “same class isomerism” is as the next educational research activity of self-reflection,peer-to-peer and professional sharing under the new curriculum reform,we have brought new hope to teachers,and established a platform for teachers to share resources,the platform of learning and the platform of development are popular among teachers,and given a shortcut to the development of teachers' specialty in the background of the new curriculum.This study carried out the research and analysis on the design and practice of junior middle school chemistry teaching based on the "same class isomerism" teaching activities.The use of teaching practices,case optimization,questionnaires,and interviews were used to discuss the implementation effects of “same-class isomerism” teaching in junior middle school chemistry on the improvement of chemistry class practice,and the development of “same class isomerism” and the development of professional competence of teachers.The role and implications of learning situations.In the process of optimizing the implementation of junior middle school chemistry "same class isomerism" teaching activities,evaluation and reflection from the perspectives of self,peer teachers,students,and three perspectives can not only effectively improve the development of teachers' professional abilities,but also help students learn about the situation.The influence has a promoting effect and helps to improve students' chemistry.The results of the study show that the students in the class that implements optimized instructional design are significantly more prominent in terms of classroom learning,enthusiasm for chemistry learning,and achievement than students who have not implemented optimal instructional design.The scores of the two classes that did not implement optimal instructional design were comparable,with no significant differences.Finally,the author puts forward some suggestions on the shortcomings and problems in the research process.
