This paper aims to clarify the efficiency and viability of remote instruction by using ICT tools to make communication more understandable, which can lead to the quality assurance of efficient research instruction and supporting autonomy for graduate students. There is an increasing need regarding how to properly instruct students who are studying abroad through the means of remote teaching and how to assure their educational quality. Thus, the first experiment was conducted on both a remote instruction and a face to face one with respect to the graduate theses. Prominent features were extracted from the usage history of the ICT communication tools used in the initial year of the instruction. Remote instruction was also conducted during the second year and qualitative data was obtained via an interview survey with graduate students. The findings show that remote instruction is more effective and increases the possibility of teaching graduate level thesis research.
