教师是特定领域教学的专业人员,这已经成为一种共识。因此,教师本身的学科知识影响着教学内容和教学效果,这就要求教师在“育人”的同时,也要做到“育己”。数学,由于其学科的特殊性,在构建“讲道理”的数学课堂的过程中,数学教师只有在明晰知识之理、了解学生之理的基础上,采用合适的教学方法(把握教法之理),才能促进数学课堂教学的有效实施。一明晰知识之理 It is a consensus that teachers are professionals in specific areas of teaching. Therefore, the teacher’s own subject knowledge affects the teaching content and teaching effect, which requires teachers to be “educated” and “educate their own people.” Mathematics, due to the particularity of its disciplines, in the process of building mathematical maths of “reasoning”, mathematics teachers should adopt suitable teaching methods only on the basis of clear knowledge of reason and understanding of students’ reasoning Reason), can promote the effective implementation of mathematics classroom teaching. A clear knowledge of reason
