课堂练习历来是小学数学教学的一个重要环节。任何一本教科书都非常重视课后习题的设计与编排,它可以使学生将所学到的知识在实践中加以运用,以检验对所学知识的理解程度,从而促进学生有效地检验学习成果。但在课堂教学中,大部分老师往往只重视了新授部分的设计,却常常忽略了练习的指导。近年来小学数学练习设计有效性的问题正成为新课改的一个瓶颈,是数学课程改革最为薄弱的环节,
Class practice has always been an important part of elementary mathematics teaching. Any textbook attaches great importance to the design and layout of after-school exercises. It enables students to apply what they have learned in practice so as to test their understanding of what they have learned and thus facilitate students to effectively test the learning outcomes. However, in the classroom teaching, most teachers tend to focus only on the design of the new part, but often neglect the practice guidance. In recent years, the effectiveness of primary school mathematics exercises design is becoming a bottleneck of the new curriculum reform, mathematics curriculum reform is the weakest link,
