数学是一门要调动逻辑性思维的学科,在小学阶段的学习重点是培养学生思维,小学四年级是一个承上启下的阶段,学习内容从简单的运算逐渐复杂化,学生思维从直观思维向抽象思维过渡,如果在这一过程打下良好的基础能为日后的学习做铺垫。根据现实情况可得出学生计算能力欠缺,成为主要障碍。 Mathematics is a discipline to mobilize logical thinking. The primary focus of learning at primary school is to cultivate students ’thinking. The fourth grade of primary school is a stage that can be accepted as a starting point. The learning content is gradually complicated from simple calculation. Students’ thinking is changed from intuitionistic thinking to abstract thinking Transition, if laid a good foundation in this process can pave the way for future learning. According to the actual situation can be drawn students lack of computing power, a major obstacle.
