The scope of this research is to develop a network platform which allows teachers and researchers to visualize their empirical educational knowledge and to share it with other members of the platform beyond the constraints such as time, place and the field of expertise. The effectiveness of the platform was examined through an empirical assessment process. In particular, the study addressed the following issues. (1) Research and analysis on the requirements of the platform and the methodology to support visualization and sharing of educational empirical knowledge. (2) Development of SNS (Social Networking Service) to facilitate connections among participants beyond the constraints such as time, place and the field of expertise. (3) Development of the additional functions of SNS which automatically work for visualizing educational knowledge and connecting relevant distributed knowledge. The results of the empirical assessment revealed that automatic visualization of implicit knowledge and conversion from distributed knowledge to collective knowledge effectively support the sharing of distributed empirical knowledge. In addition, the possibility of the platform to facilitate the reconstitution of knowledge and the creation of new knowledge was indicated.
