In today’ s engineering education, it is indispensable to develop an education program for improving communication capability. And it is important to have meaningful evaluation systems to measure the effectiveness of such a program. Nonetheless, an objective method of evaluation has not yet to be established. In this paper, I reviewed previous cases about the definition of communication and the education methods, so as to clarify the issue. I then move on to describe our struggle to develop an evaluation system which makes use of conceptual networks, rubrics, and evaluations of the scientific literacy of participants. Although these methods are integral to the definition of communication capability and educational methods, it is necessary to improve the objectivity and the feasibility.
