Research On The Design And Practice Of Layered Homework After Chemistry Class In Senior High School Guided By Quality Improvement

In Chemistry Teaching in senior high school,chemistry homework is closely related to classroom teaching.It is the expansion and extension of chemistry classroom teaching and the core and key link to achieve teaching objectives.According to the survey,chemistry homework still adheres to the traditional operation mode of "unified content and unified standard",ignoring the differences among students and hindering the comprehensive development of students.In view of this,in order to realize the original intention of education,solve the problems existing in the current high school chemistry homework,and improve the quality of homework to meet the needs of students' development,this paper makes an in-depth practical research on the hierarchical design of high school chemistry homework.The author uses the literature research method to sort out and analyze the relevant theories of hierarchical homework,summarizes the research status at home and abroad,defines homework,after-school homework and high school chemistry hierarchical homework,establishes the high school chemistry after-school hierarchical homework design system,and expounds the hierarchical principles,design principles,evaluation standards and design levels of middle school students in the process of chemistry teaching from the theoretical level.On this basis,the author carries out practical exploration.In the process of practice,the students are divided into three levels: A,B and C,and different assignments are arranged for students at different levels;To investigate the changes of students' grades after the implementation of hierarchical homework,and analyze their attitudes towards hierarchical homework.Combined with the research results,this paper puts forward the corresponding strategy of scientifically designing the layered homework after chemistry class in senior high school,that is,paying attention to the teaching objectives and taking into account the integration of disciplines;Pay attention to diversification and situational;Pay attention to hierarchy and promotion;Pay attention to individuality and universality;Pay attention to innovation and inheritance.Through the investigation and research,it is concluded that layered homework plays an important role in promoting students' all-round development and cultivating students' subject literacy,which should be highly valued by front-line teachers and educational researchers.The design of layered homework content after chemistry class should be scientific and regular,so that the layered design of chemistry homework can provide help for the all-round development of students.
