本着以学生发展为本的理念,教师要处理好“教与学”的关系,真正确立学生的主体地位,承认学生中蕴藏着巨大的潜能,让学生在教学活动中发展自己。特别是要解决数学学科的抽象性与思维水平之间的矛盾,就要让学生“动”起来,耳、眼、口、手、脑“全频道”接受,“多功能”协调,“立 In line with the concept of student development, teachers should properly handle the relationship between “teaching and learning”, truly establish the students’ dominant position, admit that students have tremendous potential, and enable students to develop themselves in teaching activities. In particular, to resolve the contradiction between the abstraction of mathematics and the level of thinking, students should be motivated to accept the “omni-channel” of ear, eye, mouth, hand and brain, and “multi-functional” coordination.
