Abstract
Adopting worked examples having operation step annotations or not and representing worked examples alternating, the present study had researched 48 second Grade pupils learning about the rules of the four fundamental admixture operations of arithmetic by operating worked examples. As a result, most of pupils could learn the rules of the four fundamental admixture operations of arithmetic with brackets by worked examples, but the number of pupils could learn the rules of the four fundamental admixture operations of arithmetic without brackets wasnt significant; Operation step annotations had obvious effect on pupils learning about the more difficult rules of the four fundamental admixture operations of arithmetic, but had no obvious effect on pupils learning about the easy rules of the four fundamental admixture operations of arithmetic; Pupils needed different quantities of worked examples when learning different difficult operation rules.
