思维定式,是指人们利用已有的知识和经验,带着某种即定的框架模式去认知新事物时,得出“应该怎样”的思维活动.思维定式对人的大脑思维活动存在两种作用,当它有利于对认识学习新材料时产生正向迁移时,它起的作用是积极的,当它对于认识学习新材料时产生干扰时,即产生负向迁移时,它的作用则是消积的.例1如图1,长木板ab的a b s b端固定一档板,木板连同档板的质量为M=4.0kg,a、b间距离图1s=2.0m.木板位于光滑水平面上.在木板a端有一个小物块,其质量m=1.0kg,小物块与木板间的动摩擦因数μ=0.
Thinking style refers to people’s thinking activities that use the existing knowledge and experience to recognize new things with some kind of framework mode, It has two roles. When it facilitates the positive transfer of knowledge of new materials, it plays a positive role. When it interferes with the recognition of new materials, that is, it produces negative migration The role is consumer product Example 1 Figure 1, absb end of the long board ab fixed a baffle board, along with the quality of the board M = 4.0kg, a, b between the distance Figure 1s = 2.0m. In the horizontal plane, there is a small block at the a end of the wood board, the mass m = 1.0kg, the dynamic friction coefficient μ = 0 between the small block and the wood board.
