| After the introduction of the "double reduction" policy,"burden reduction" has once again become the focus of society.Homework as a means of consolidating teaching effectiveness and a continuation of classroom teaching has always attracted attention in the field of education.The essence of "double reduction" is to increase efficiency,and optimizing the design of operation is also one of the ways to reduce burden and increase efficiency.Function is one of the four main lines of high school mathematics course content,and it is very necessary and important to explore the optimization of homework in high school function chapter under the background of "double reduction".In this study,we first read and organize relevant literature to understand the current research status of mathematics homework under the background of "double reduction".Secondly,through the questionnaire survey method and teacher interview method,the current situation of the homework of the function chapter of the first year of high school students was investigated and analyzed.The survey content of the student questionnaire mainly includes the learning situation of students’ mathematics subjects,the current situation of mathematics homework,students’ understanding of homework,and the source of homework after class.The purpose of teacher interviews is to understand teachers’ views and practices on homework optimization and learn from their experience.Thirdly,the goals of mathematics homework optimization are discussed,and the requirements of the "double reduction" policy,curriculum standards,and textbook content are analyzed,and the principles and strategies of mathematics homework optimization are given.Then,according to the above research results,homework optimization is carried out,and specific cases of after-class homework optimization in function chapters are given,including layered homework,cooperative inquiry type,practical research type,open homework,etc.,for teachers’reference.Finally,the case is implemented in the practice school,and the results of student performance,teacher evaluation,and student feedback are analyzed to verify that homework optimization is necessary and feasible. |
