Abstract Based on the description of academic quality and academic level in the Compulsory Education Chemistry Curriculum Standard (2022 edition), and according to the characteristics of students and the actual teaching content, the author constructs the 3D matrix mode (homework objectives, homework forms and homework requirements) of middle school chemistry unit homework design. Taking the unit teaching content of water in nature as an example, this article systematically explains the process of homework design, implementation and evaluation, and makes improvement and reflection on the implementation of homework.
