中学数学教学大纲中指出要培养学生的运算能力,逻辑思维能力和空间想象能力。解题能力的高低实际是以上三种能力的综合体现,数学学习是以数学问题为出发点,解题为中心的学科,提高学生对数学问题分析认识能力和严谨的解题思维能力,这是提高学生数学素养的重要标志。常言道:“数学学得好不好,首先看会不会算。”运算能力是数学解题能力的基石。常有学生抱怨自己计算太粗心。其实,粗心仅仅是个性以及心智集中持续时间短的表面反应,是相对不同的个体的性格而言。对数学知识掌握不
High school mathematics syllabus pointed out that to cultivate students’ computing power, logical thinking ability and spatial imagination. The level of problem solving ability is actually the combination of the above three kinds of abilities. Mathematics study is based on the math problem as the starting point and problem solving as the center of the discipline to improve students’ ability of analyzing and understanding math problems and rigorous problem solving thinking ability, which is to improve An important symbol of students’ mathematical literacy. As the saying goes: “Mathematical learning is good, first look will not count.” Computing power is the cornerstone of mathematical ability to solve problems. Often students complain about calculating too carelessly. In fact, carelessness is just the personality and mental focus of the short duration of the surface reaction is relatively different individual’s personal terms. Mastery of mathematics is not
