一、对作业的认识清代教育家颜元说过:“讲之功有限,习之功无已。”在数学教学过程中,我们不仅要重视课堂上知识的传授,更要重视“习行之功”。数学学科主要培养学生运算能力、逻辑思维能力、空间想象能力,以及运用所学知识分析问题、解决问题的能力。学习数学只看书不做题不行,埋头做题不总结积累也不行。数学能力提高的关键在于科学有效地做题。学生由于先天遗传、家庭环境、社会环境等各种因素的不同,在认知方法、认知发展和能力等方面存在明显的 First, the operation of the Qing Yan Yan educator said: “In the teaching of mathematics, we should not only pay attention to imparting knowledge in the classroom, but also pay attention to ”The exercise of power". Mathematical disciplines mainly cultivate students’ computing ability, logical thinking ability, spatial imagination ability, as well as the ability to analyze and solve problems by using the learned knowledge. Learning mathematics not only do not read the book does not work, do not concentrate on the problem accumulation does not work. The key to improving mathematics ability is to make scientific and effective questions. Students due to genetic, family environment, social environment and other factors of different, in cognitive methods, cognitive development and ability there is a clear
