数学是一门前后知识联系紧密的学科,新知识的理解和掌握往往需要旧知识作为基础。而我们经常发现一种现象:学生对于数学知识的学习较为死板,他们只会机械地照搬老师所教授的解答方法,然而举一反三能力却比较差。另一种现象是:学生对于同一类型的题目出错率较高,就算老师强调过很多遍,但是学生还是容易将相关概念混淆,造成一次次失分。这些知识的混淆日积月累,既打击了学生的学习积极性,也给老师们的教学带来了不小的麻烦。培养学生的思维能力是现代教育的一项基本任务。 Mathematics is a subject that is closely related to knowledge before and after. The understanding and mastery of new knowledge often requires old knowledge as a basis. And we often find a phenomenon: students are more rigid about learning mathematics, they only mechanically copy the answer method taught by the teacher, but they are not good at all. Another phenomenon is: students for the same type of problem a higher error rate, even if the teacher stressed many times, but students are still confused with the concept, resulting in a failure points. The confusion of these knowledge over time, both to combat the enthusiasm of students, but also to the teaching of teachers brought no small trouble. Cultivating students’ thinking ability is a basic task of modern education.
