激活是一个认知心理学概念.激活也是一种解题策略[1],如复习与新知识有关的旧知识,可以激活需要用新知识来解答的数学题.如“设n≠4k,n∈N,k∈N,试证:1n+2n+3n+4n一定能被5整除.”分析可用特殊激活一般的策略,12+22+32+42=1+4+9+16=3013+23+33+43=1+8+27+64=100…1n+2n+3n+4n当 Activation is a concept of cognitive psychology. Activation is also a problem solving strategy [1]. For example, reviewing old knowledge related to new knowledge can activate math problems that need to be solved with new knowledge. For example, “set n≠4k,n ∈N,k∈N, testimonial: 1n+2n+3n+4n must be divisible by five." Analysis can be used to activate the general strategy, 12+22+32+42=1+4+9+16=3013+ 23+33+43=1+8+27+64=100...1n+2n+3n+4n
