再谈“数学”与“生活”——《认识方向》同课续构教后感

Second Discussion of Mathematics and Life: Reading Afterthought

"生活数学"长期、随意的使用已造成了语意的模糊、语境的泛化。生活数学到底姓什么?婆家是谁?这并不重要。让学生从生活中学习数学,在丰富的"生活体验"中学习数学,不失为学习的一种方式;同样变"悟"为"焐",让学生直接获取间接经验,然后再运用理解,也是学习的一种方式。教学有法、教无定法、适机选法、重在得法。

Casual use of the term ＂life mathematics＂ over a long period has caused its vague meaning and contextual expansion. It does not matter what ＂life mathematics＂ is, while it counts that students can learn mathematics from life, and from colorful life experiencing process. Meanwhile, students should be offered chances to acquire indirect experience in a direct way, and then they use them in their life for a deep understanding. Teaching has its approach, while the method is not fixed, and therefore selecting methods should be necessary and proper, in which techniques are most valuable.
