学生的运算能力在高中阶段占据很重要的基础地位,它制约着后续的数学学习,也影响物理、化学的学习.从目前的数学评价来说,运算准确还是一个很重要的方面,运算屡屡出错会打击学生学习数学的信心.从个性品质上说,运算能力差的学生往往粗枝大 The student’s computing ability occupies a very important basic position in the high school stage, it restricts the follow-up mathematics learning, but also affects the physics, chemistry learning. From the current mathematical evaluation, the operation accuracy is still a very important aspect, the operation is often wrong It will impede the students’ confidence in learning mathematics. From the aspect of personality quality, students with poor numeracy skills are often overwhelming.
