学习不是老师把知识简单地传授给学生,而是学生自己建构知识的过程。教师的职责在于让学生在创造教学中学习数学,在“做”数学中学习数学,让数学的发展历程在学生身上重现。因此,教师要引导学生参与“做”数学的全过程,不仅要在课前主动参与,课中自主参与,课后更要积极参与。 Learning is not a simple transfer of knowledge from the teacher to the student, but the process by which the student constructs knowledge. The teacher’s job is to let the students learn mathematics in creating teaching and mathematics in mathematics so that the course of mathematics can be reproduced in the students. Therefore, teachers should guide students to participate in the whole process of “doing ” mathematics. They should not only take the initiative to participate in class before class but participate actively in class, but also actively participate after class.
