This study begins by connecting semantic elaboration with conceptual understanding and syntactic elaboration with proce-dural understanding in the context of fractions.

Findings are that, while some students emphasized one form of elaboration over the other, some students demonstrated use of both forms of elaboration. Indeed, it is wondered if semantic and syntactic elaboration should be seen as more complementary than adversarial.
