小学数学中的“转化思想”渗透于各类知识之中,在学习的各个阶段都起重要作用,尤其在“图形面积”计算教学中把“转化思想”反复渗透,引导学生利用旧知识来解决新问题,进而放手让学生用“转化思想”探究活动,深入理解“转化思想”并将其变为解决问题的有意识的行为.但在众多课堂教学中“转化思想”的体现如蜻蜓点水般表面化,“转化思想”对学生数学学习的正面推动作用有些旁落.本文通过对面积教学的探索,并以此内容为媒介增强学生主动运用“转化思想”的意识,有效地传递“转化思想”的正能量.
In elementary mathematics, “transformation thinking ” permeates all kinds of knowledge and plays an important role in all stages of learning, especially in “graphic area ” calculation teaching “transformation thinking ” repeated infiltration, guidance Students use the old knowledge to solve new problems, and then let the students explore the activity with “transformation thinking ” and deeply understand “transformation thinking ” and turn it into a conscious behavior to solve the problem.But in many classroom teaching The transformation idea is superficially superficial, and the thinking of transformation translates to a positive impetus for students ’mathematics learning.Based on the exploration of area teaching and using this as a medium to enhance students’ initiative use, Thinking “consciousness, effectively transfer ” conversion thinking "positive energy.
