在数学教学中,学生完成相应的数学练习,是学生的一种学习方式。它既是教学的重要环节,也是课堂教学的延续和补充,有着重要的作用。学生在练习中,通过积极思考,达到对知识的巩固和提高。同时教师能够从学生的作业情况中,及时了解学生对所学知识的掌握情况,由此调整教学进度,修改教学设计,查缺补漏,让学生为以后新知识的学习打下坚实的基础。而对于学生的作业,往往需要进行评价。在小学数学课程标准中,关于评价是这样描述的:评价要关
In mathematics teaching, the students to complete the corresponding math exercises, is a way for students to learn. It is not only an important part of teaching, but also a continuation and supplement of classroom teaching, which plays an important role. Students in practice, through positive thinking, to consolidate and improve knowledge. At the same time, teachers can keep abreast of the mastery of students 'knowledge from the students' homework situation, so as to adjust the teaching progress, modify the teaching design, and find out the gaps so that students can lay a solid foundation for future learning of new knowledge. For students' assignments, they often need to be evaluated. In the elementary mathematics curriculum standards, the evaluation is described as follows: the evaluation to be closed
