A Practical Study On Chemistry Teaching To Promote The Development Of High School Students'"Changing Concept And Balancing Thought"

The quality of "change concept and balance thought" is an important part of the students' development of the core quality of chemistry.This paper discusses the concept connotation of "change concept and balance thought",the high school chemistry knowledge,teaching design and teaching effect that promotes the development of "change concept and balance thought" of high school students.With the high school chemistry theory knowledge as the carrier,follow the creation of problem situation,trigger real thinking;Students as the center,independent summary of the law;Contact with life chemistry,pay attention to the combination with STSE;On the basis of experiments,the teaching design principles such as carrying out higher level exploration activities and so on,the teaching design of chemical energy and heat energy,chemical energy and electric energy,and chemical reaction rate and balance for three class hours is carried out in order to promote the development of students' quality of "changing concept and balance thought".The experimental class and the control class were selected from two classes with similar development levels of chemical core literacy in grade one of a middle school in kunming.In the experimental class,the teaching design based on the development of students' "change concept and balance thought" is implemented,and the teaching ideas of cognition,humanism and constructivism are followed in the teaching organization.At the same time,a classroom observation scale based on LICC paradigm was designed to conduct classroom observation in the experimental class and routine teaching in the control class.Combined with classroom observation and after-class exercises to evaluate the classroom effect,and compared with the performance of the students in the control class,it is found that the teaching design following the above principles can effectively promote students' classroom enthusiasm,and is conducive to cultivating students' active thinking ability and dialectical thinking of the unity of "change-conservation".It shows that the design and implementation of chemistry teaching based on the development of high school students' "change concept and balance thought" can promote the development of students' "change concept and balance thought" accomplishment.
