Where should ''you'' go in a math compare problem?

This study examined the cognitive effects of self-referencing in math word problems in 100 3rd, 4th, and 5th graders. Two types of compare problems were used: compare unknown (CU) and referent unknown (RU). The word you was placed in the problems either as the known or the unknown term. For the CU problems, self-referencing facilitated students' performance regardless of the position of the you term. When self-referencing was applied, students asked for fewer repeats and solved these CU problems faster and with greater accuracy. For the RU problems, however, students benefited from self-referencing only when the self term was placed as the compare (known) term. When the you term was placed as the referent term, the facilitative effect of self-referencing disappeared. The position of the you term in a RU problem apparently has an impact on the translation procedure required in solving the problem. Further research on the cognitive processing issues raised by these data is suggested and the educational implications of the findings are discussed.
