Winne's (1995) thoughtful and proactive article stressed the role of m
etacognitive processes in self-regulated learning. Although metacognit
ion and forms of knowledge are important, they provide an incomplete p
icture of the processes involved in self-regulation. Theoretical and e
mpirical evidence support the inclusion of student perceptions and mot
ivational processes as integral components of self-regulation. Researc
h incorporating the operation of student knowledge and perceptions wil
l make a significant contribution to the self-regulation literature an
d have important implications for instruction.
