作业是课堂教学的补充,是老师了解学生掌握知识的必要手段。据了解,目前作业设计,普遍形式单一,随意性较大。尤其是数学课堂作业当堂完成少,课后完成多。针对这一现象,我始终围绕效果、效率、效益的“有效教学”理念,在优化作业设计,追求教学质效方面作了实践与研究,并取到了较好的成效。一、立足文本,变简单为精细。课堂作业设计必须以紧扣文本为前提,让学生练习到应该练习的东西,这样才能确保课堂作业与课堂教学目标的一致性,从而实现课堂作业内容的有效性。学生每人都有课本和补充习题,我们要求每个老师对课本和补充习题上的题目的意图进行研究分析,并根据课时教学的要求以及习题的难易程度进行分类, Homework is a supplement to classroom teaching and is a necessary tool for teachers to understand students’ mastery of knowledge. It is understood that the current job design, the general form of a single, more arbitrary. In particular, when the math classroom work is completed less, after the completion of more. In response to this phenomenon, I always practice and study on the concept of “effective teaching” of effectiveness, efficiency and effectiveness in the aspect of optimizing homework design and pursuing the teaching quality of teaching, and achieved good results. First, based on the text, change simple to fine. Classwork design must be based on the premise of tight text, allowing students to practice what should be practiced, so as to ensure the consistency of classroom assignments and classroom teaching objectives so as to achieve the effectiveness of the content of the classroom assignments. Each student has a textbook and supplementary exercises, we ask each teacher to study and analyze the intent of the textbooks and supplementary exercises, and according to the requirements of class teaching and the difficulty of the exercises classification,
