This paper focuses on English homework design in compulsory education under the “Double Reduction” policy. It first analyzes the research background and significance, reviews relevant literature at home and abroad, and points out existing problems. Then, based on constructivist learning theory, multiple intelligences theory, and formative assessment theory, it proposes design principles like reducing burden and increasing efficiency, and design strategies such as layered design. Although the research has limitations, it provides theoretical and practical references for English education reform.
