Research On The Design Of A Middle School Chemical "Solution" Large Unit Integrating Aesthetic Education

In 2022,the new curriculum standards for chemistry in compulsory education were promulgated,and the teaching objectives of chemistry in junior middle schools were developed in the direction of comprehensiveness,comprehensiveness and literacy in accordance with the requirements of the curriculum standards.The new curriculum standard puts forward the core quality of chemistry in compulsory education,which is closely related to the quality of chemistry in high school,which also indicates that the task of chemistry teaching in junior high school should not only integrate knowledge,enhance ability and cultivate quality,but also pay attention to the connection between junior high school and senior high school.In addition,the new curriculum standard calls for the development of large unit teaching led by "big concept",requires the optimization of curriculum content,the overall design of teaching,the play of "big concept" of large unit teaching,promote the cross and fusion of knowledge,connect into a comprehensive knowledge system.To realize the great task of "cultivating top-notch innovative talents and gathering talented people from all over the world" emphasized in the report of the Top 20.In the same year,The State Council issued the guidance document on aesthetic education,requiring the implementation of aesthetic education in schools,the cultivation of students’ aesthetic quality,aesthetic education,promoting the integration of the five education,the implementation of moral cultivation.This paper tries to explore how to excavate the potential value of chemical beauty,promote the implementation of aesthetic education of chemistry and highlight the value of education of chemistry.Through aesthetic cognition,aesthetic appreciation,aesthetic experience,aesthetic behavior and other dimensions of junior high school students aesthetic quality investigation,found that students have a certain aesthetic foundation,suitable for the integration of aesthetic education in teaching,should focus on the cultivation of aesthetic appreciation ability.Based on literature research and teacher interviews,it is found that there are few researches on large unit teaching of chemistry,and there are some problems such as knowledge integration difficulties and concept cognitive biases.Aesthetic education contains unique thinking logic,and its highest state is aesthetic creation;Large unit teaching also has corresponding thinking mode,its highest level is the comprehensive and innovative application of knowledge.Aesthetic education and large unit teaching design coincide with each other from the Angle of logical thinking.Therefore,this paper puts forward the big unit teaching mode integrating aesthetic education and "maintaining aesthetic emotion-clarifying the theme of the big unit of chemistry,integrating the knowledge of the big unit of chemistry-highlighting the concept of chemical aesthetics,clarifying the goal of the big unit of chemistry-penetrating aesthetic education,stimulating aesthetic consciousness-improving the teaching links of the big unit of chemistry,optimizing the evaluation of the big unit of chemistry-forming aesthetic thinking.Carry out the seven-step teaching strategy of chemical aesthetic action-set up large unit homework,reflect on large unit teaching-Promote the creation of chemical aesthetic.Based on this,we design a large unit teaching activity of Solution,which includes four sub-topics: "Initial understanding of solution","homemade acid-base indicator","acid-base neutralization reaction",and "the Kalechanging in Solution",and apply it into teaching practice.The practical feasibility of this model is verified by teaching feedback survey.
