This article explores the nature of the relationship between intrinsic and
extrinsic motivation in schools, and in particular examines critically the
assertion that these processes are necessarily antagonistic. The weight of
evidence suggests that rewards in the form of school grades and the focus o
f many students on doing well, gradewise, need not necessarily interfere wi
th learning for its own sake. Educational implications of these findings ar
e considered. One such implication is that focusing on students' interests
can be a valuable motivational strategy.
