一、计算研究的背景分析1.课程改革和学生发展凸显研究需要小学生计算能力的培养是小学数学教学的一项重要任务,是学生今后学习数学的重要基础。不论是在小学数学教材中还是在各级各类的练习卷中,计算所占的比重都很大,尤其是在试卷的题型分配上来看,计算是作为基础部分得分题出现的,从整张试卷来看,涉及计算内容的题目在试卷中也要占到80%以上,除此之外,还有更多综合性知识的呈现都需要有正确计算的落实。因此,计算能力不仅仅是小
First, the background analysis of computational research 1. Curriculum reform and student development highlights the need for primary school students to develop computational ability is an important task in mathematics teaching, is an important basis for students to learn mathematics in the future. Whether in primary school mathematics textbooks or at all levels of various types of practice volume, the proportion of the calculation is very large, especially in the question paper assignments on the point of view, the calculation is based on part of the score problem appears, Zhang papers, the topics involved in the calculation of content in the papers also account for more than 80%, in addition, there are more comprehensive knowledge of the presentation requires the correct calculation of the implementation. Therefore, the computing power is not just small
