Reflections on the Design of Junior High School Science Homework Pointing to the Core Literacy under the Background of "Double Reduction"

Science homework is an important part of junior high school science teaching and learning, playing an important role in the whole subject curriculum teaching system. How to design homework scientifically, reasonably and effectively according to the teaching contents and learning conditions is the key exploration of junior high school science teaching under the background of “double reduction”. Based on the understanding of the core literacy of science and the analysis of the current status of science homework in junior high schools, we combined with the teaching practice of science homework design, and considered the improvement path for the design of junior high school science homework that points to the core literacy under the "double reduction" policy. Teachers can proceed with the following four aspects to improve the quality of homework design: designing conceptual homework from science concepts to consolidate basic knowledge; designing improving homework from science thinking to enhance the quality of assignments; designing practice-based homework from inquiry and practice to enrich the form of assignments; designing value-oriented homework from attitude and responsibility to bring out the value of educating people, so as to truly help students achieve "quality improvement, efficiency increase, and burden reduction" in learning, and cultivate students' core literacy.
