作业,是数学教学中必不可少的重要环节,它是课堂教学的延伸,学生在完成作业的过程中,再一次重温课堂所学的知识,并将获得的能力初步地加以运用。完成作业的过程是学生一次完全自主的学习,也是一次师生课堂教与学的效果的呈示。 Homework is an indispensable part of mathematics teaching. It is an extension of classroom teaching. Once the students finish their homework, they again review the knowledge they have learned in class and apply the acquired ability initially. The process of completing homework is a complete and independent study by students and a demonstration of the effect of classroom teaching and learning by teachers and students.
