一、不注意追求概念教学的科学性与严密性。某些教师在概念教学时,有时为了快速地得出某一个概念,而忽略了探究方法的科学性和过程的严密性。如果仅凭一个事例就妄加结论,既不科学,也不严密。长期以往,学生会形成一个误解——只要有一个是对的,得到的概念就正确。 First, do not pay attention to the concept of scientific and rigorous pursuit of teaching. Some teachers in the concept of teaching, sometimes in order to quickly come to a concept, while ignoring the scientific method of inquiry and the rigor of the process. It is neither scientific nor rigorous to make a conclusion by just one example. Long ago, students formed a misunderstanding - as long as one is right, the concept is correct.
