《义务教育数学课程标准(2011年版)》提出:“学生应当有足够的时间和空间,经历观察、实验、猜测、计算、推理、验证等活动过程。”因此,在教学中,教师不应将已经分析得很清楚的问题直接呈现给学生,也不应将方法直接手把手地教给学生,更不要把教材作为定论与共识,而应利用这些活动加深学生的学习体验,给学生一个足够的空间,促使学生充分利用已有的知识基础和经验自主地建构数学知识,培养学生的数学能力。
The Compulsory Education Curriculum Standard (2011 Edition) states: “Students should have enough time and space to go through the process of observation, experiment, speculation, calculation, reasoning and verification.” Therefore, in teaching, teachers do not The problems that have been analyzed clearly should be presented directly to the students. Nor should the methods be directly taught to the students, not to use the teaching materials as a conclusion and consensus, but should be used to deepen the students’ learning experience and give students a sufficient Of space, to promote students to make full use of the existing knowledge base and experience to build mathematical knowledge autonomously, to develop students’ mathematical ability.
