Abstract: This experiment used context personization and rewording as problem-solving strategies to explore their effect on the students in the solving of addition an substraction word problems.There was a 4×3×2×2(experimental groups×mathematical ability levels×familiar degrees×relation of situation and operation mixed design.Below are the conclusions:(1)In general,the students can make context personization and rewording independently.(2)In this experiment,it is no good for students of high mathematical ability level to use them seperately,but to use them unitedly or use the strategy of context personization singly can bring more benefit to students of middle and low mathematical ability level than high leveled students.(3) It has effect when strategy of context personization is used to solve unfamiliar problems in the context.(4)It has no effect when used to solve irrelevant problems in relation to situation and operation,(5)Besides the narrative problem scheme,there is a structural problem scheme.The teacher can teach students to use these two strategies.

Key words: strategy of context personization, strategy of rewording, problem scheme
