Proposal and Evaluation of an Interface to View SNS Data Accumulated through Practical Learning

Abstract

Social Networking Services(SNS) are now popular, and there are several activities in which they use SNS to accumulate users' idea and to share knowledge. We have been working on a method to store and share "Learning Process" on SNS, in order to bring about more effective learning. In this method, a student usually posts articles or observations in their individual space, and other students are free to post comments. In this research, we propose an interface to visualize these articles accumulated in users' individual spaces. This interface features a zoom-able user interface and an overview of all users' articles. We can then evaluate the usability of the interface to view data accumulated in SNS through practical learning activities that we held so far. Experimental results have indicated that a proposed interface is more easily accessible and effective than existing SNS interfaces. Also, students have been using it with a high degree of satisfaction.
