小学生不易理解抽象概念,能凭借形象进行思维.根据这一特点进行直觉思维训练,可收到良好效果.直觉思维是指让学生利用丰富的材料“感觉”出正确的结论,形成正确的概念.直觉思维还可使学生“越级思考、跳跃思维”看到某种现象时产生“顿悟”.具体训练方法例举如下:例一、一年级教学20以内退位减法的算理算法:A、用黑白围棋子做学具.让每个学生把10粒白子放在左边,4粒黑子放在右边,教师指挥动作、观察:(1)一次移走9粒,看还剩下几粒?(5粒)怎样看出来的?(剩下的1粒白子加上4粒黑子)把白子放在原位,用同样的过程移走8、7、6、
Students can easily understand the concept of abstraction and can think by virtue of the image, and according to this feature, intuition thinking training can receive good results. Intuitive thinking refers to letting students use the rich material “feeling ” to get the correct conclusion Concept. Intuitive thinking can also make students “leapfrog thinking, jumping thinking ” to see a phenomenon produced “Epiphany ” Specific training methods are as follows: Example 1, the first grade teaching less than 20 arithmetic abatement subtraction Algorithm: A, with black and white chessmen do learning tools, so that each student put 10 white on the left, 4 sunspots on the right, the teacher command movement, observe: (1) remove the 9 at a time, to see the rest How many grains? (5 grains) How do you see? (The remaining 1 white piece plus 4 pieces of black seed) Put the white piece in place and use the same procedure to remove 8, 7, 6,
