In this article, I reviewed current state of researches about mathematics instruction in Korea and sought ways and methodologies of future research. I analyzed articles which were published after year 2000 and were targeted to mathematical instruction itself. After collecting articles, I classified them according to research subject, method and analysis framework, purpose and focus, research perspective and keyword. Subsequently, I analyzed tendency of each research and theoretical framework of them. Based on upper results, I drew directivity of mathematics instruction research at two aspects. First, I found and suggested elements with which framework of mathematics instruction analysis should equip. Secondly, I explored main tasks of mathematics instruction research.
