The purpose of this study is to improve learner\'s mathematical reasoning and representation
ability through instruction applicated metacognition strategy.
Therefore, first of all, I made up the teaching-learning plan used instruction applicated
metacognition strategy and applied it.
After that I verified the effects of it by analyzing to improve mathematical reasoning and
representation ability of 3rd grade students in elementary school or not.
The research questions in this study was designed to look for any differences of
mathematical reasoning (inductive reasoning ability and analogical reasoning ability) and also
to look for any differences mathematical representation ability (picture representation, language
representation, symbolic representation).
It is concluded that mathematics learning used instruction applicated metacognition strategy
was effective in the improvement of mathematical reasoning and representation ability. That is,
instruction applicated metacognition strategy in class can improve mathematical attitude,
thought, and knowledge ・ function gradually.
The present findings indicate that educational application which motivates instruction
applicated metacognition strategy can improve mathematical reasoning and representation
ability in elementary students.
However, the above research is limited to generalize the effects of it, because the research was
implemented during the short period, only 3rd graders of elementary school were tested and the
learning effects were proved just in terms of 1. numbers up to 10000 2. addition and extraction unit.
