如何在日常教学过程中培养小学生的归纳推理能力?请看以下这个案例。一、案例在长方体和正方体的综合练习上,我设计了如下这道题:先观察下面的各组摆放情况,再填写表格。(每个小正方体棱长是1厘米)——师:你能发现小正方体排列的规律吗?生1:第1个图形是1层,是1个正方体;第2个图形是2层,规律是1+2=3是3个正方体:第3个图形是3层,规律是1+2+3=6,是6个正方体:第4个图形是4层,规律是1+2+3+4=10,是10个正方体:第5个图形是4层,规律是1+2+3+4+5=15,是15个正
How to train pupils in inductive reasoning ability in daily teaching? See the following case. First, the case In the comprehensive practice of cuboids and cubes, I designed the following question: First observe the placement of the following groups, and then fill in the form. (Each small cube edge length is 1 cm) - Teacher: Can you find the law of small cuboid arrangement? Health 1: The first graph is 1 layer, is a cube; The second graph is 2 layers, the law Is 1 + 2 = 3 is 3 cubes: the 3rd graph is 3 levels, the law is 1 + 2 + 3 = 6, which is 6 cubes: the 4th graph is 4 levels and the law is 1 + 2 + 3 + 4 = 10, is a 10 cube: the fifth graph is 4 layers, the law is 1 + 2 + 3 + 4 + 5 = 15, is 15 positive
