计算在小学数学知识体系中占有极大的比例,学生计算能力的高低直接影响着学生学习的质量。教师如何提高学生的计算能力成了小学数学教学研究的重要问题。笔者在多年的教学中,尝试将比较的方法应用到计算教学实践中,取得了较理想的效果。一、运用比较,帮助理解算理著名教育家赫尔巴特说:“所有比较确定的知识,都必须从计算开始。”而算理的理解则为学生计算能力的提高形成了有力的支撑。在教学中除了利用操
Calculation occupies a very large proportion in elementary mathematics knowledge system, the level of students ’computing ability directly affects the quality of students’ learning. How teachers improve students’ computing ability has become an important issue in primary school mathematics teaching and research. The author in many years of teaching, try to compare the method applied to the calculation of teaching practice, and achieved more satisfactory results. First, the use of comparisons to help understand the well-known arithmetic Herbart said: “All the more certain knowledge, must start from the calculation. ” The understanding of the arithmetic is for students to improve the computing power has formed a strong support . In addition to teaching use of exercises
