Research On The Design And The Application Of Chemistry Practical Homework In Middle School Based On The Idea Of "School-Home Cooperation"

In the context of "double reduction" policy,homework improvement has become a key requirement to achieve the educational goal of strengthening morality education.The addition of practical homework in the compulsory education stage is conducive to improving the quality of teaching,and at the same time,it is conducive to giving full play to the initiative of parents,establishing a bridge between family education and subject education,and realizing home-school collaborative education.The chemistry practical homework under the concept of "home-school collaboration" is of great significance to the realization of the educational function of chemistry.The thesis is devoted to discussing two issues:"how to design junior high school chemistry practical homework under the concept of "home-school collaboration" based on junior high school chemistry curriculum" and "how to evaluate the quality of students"junior high school chemistry practical homework based on the quality concept of all-round development ".Based on theoretical analysis,homework design,homework evaluation and other research components,this thesis believes that the practical homework in junior high school chemistry under the concept of home-school collaboration is of great value for improving the educational function of the chemistry subject,and is conducive to the development of the core literacy of the chemistry subject and the formation of innovative thinking and practical ability to achieve comprehensive self-development.Students show a high level of overall performance in this practical homework,perform better in the dimension of artistic creativity,and are relevant in the dimensions of scientific knowledge and scientific culture.The research results show that students can show a high level of comprehensive quality in the process of completing chemistry practical homework,and chemistry practical homework can promote students’all-round development to a certain extent.The thesis consists of five chapters.The first chapter is the introduction,which clarifies the research questions,the current research status at home and abroad,and analyzes the purpose,significance,methods and ideas of the research.The second chapter is the core concept and theoretical basis,and defines the concepts of"home-school collaboration" education,practical homework,chemistry practical homework,etc.,and puts forward the theoretical proposition of this research.The third chapter is the research design,which details the design,implementation and evaluation of junior high school chemistry practical homework under the concept of "home-school collaboration".The fourth chapter is the result of the research,which analyzes the students’ homework performance from the overall performance and the three dimensions of scientific knowledge,scientific culture,and artistic creativity.The fifth chapter is the conclusion,inspiration,innovation and prospect of the research.
