在数学学习过程中,面对学生无从下手的问题,教师应该着力引导学生通过对题目类型的转变,尝试运用已有知识进行思考。这种化归思想对于学生数学能力的形成具有重要的促进作用。因此,本文提出要依托教材,努力发掘化归思想;要紧扣课堂,穿插化归思想;要注重拓展,践行化归思想,从而提升学生的学习能力。 In the process of mathematics learning, facing the problem that students can not start, teachers should try their best to guide students to think through existing knowledge by changing the type of topic. This thought of return to the formation of the mathematical ability of students has an important role in promoting. Therefore, this article proposes to rely on teaching materials, and strive to explore the idea of ​​return to the past; to be closely linked to the classroom, interspersed with thought; to focus on expanding, practicing the return to thought, so as to enhance students’ ability to learn.
