例谈课堂中“数学实验支架”的构建

On the Construction of "Mathematical Experiment Scaffold" in Class

"数学实验"是一种为了获得某种数学结论,检验某种数学猜想,解决某类数学问题,而引导学生在创设的特定物质条件下,在多种思维活动的共同参与下,最后领悟概念和解决问题的教学手段。而"支架式教学法"则以"最近发展区"为指导,只在超出学生当前水平时,教师才给予"支架"协助,直至学生能自己承担任务或掌握知识。因此两者的结合,需要教师在将实验的精神赋予学生的同时,构建恰当的教学支架,使学生的学习能力得到提升。

"Mathematics experiment" is a kind of in order to obtain a certain mathematical conclusion, test a certain mathematical conjecture, and solve a certain type of mathematical problem, and guide students to comprehend the concept with the participation of various thinking activities under specific material conditions created. And teaching methods to solve problems. The "scaffolding teaching method" is guided by the "recent development zone", and only when the students’ current level is exceeded, the teacher will give "scaffolding" assistance until the students can take on the task or master the knowledge.Therefore, the combination of the two requires teachers to build an appropriate teaching scaffold while empowering students with the spirit of experimentation, so that students’ learning ability can be improved.
