The purpose of this study was to investigate whether providing the
opportunity of metacognitive automation and corrective feedbacks would
impact on the mastery level of a learning strategy. The experimental group
included 42 senior college students and received the opportunity of
metacognitive automation and corrective feedbacks in mid of pretest and
posttest of a Test-Taking Strategy instruction. The control group included 45
senior college students and received the opportunity of corrective feedbacks
only in mid of pretest and posttest of the strategy instruction. The research
results showed as follows. First, the two groups did not show any difference
on the pretest. Second, the experimental group with the opportunity of
metacognitive automation and corrective feedbacks could reach to the mastery
level of the strategy. On the contrary, the control group with the opportunity
of corrective feedbacks only could not reach to the mastery level of the
strategy. Therefore, the mean of two groups on the posttest were significantly
different each other. Third, there were no significant difference on the final
term exam of the two groups. At the discussion, the research results were
analyzed in terms of the research questions and suggested some contributions
regarding the research participants and this field.
