This study is concerned about how teachers can enhance interactivity during face-to-face lectures. Toward this objective, the authors have developed a teaching tool which allows learners to send feedback during a lecture and displays the feedback, in real-time, on a projected screen (herein referred to as a "blackboard") (Sato et al. 2002). In this paper, the "Board Mediated Communication" (BMC) method is proposed as a critical feature of the tool to promote interactions both of a teacher-to-learner and learner-to-learner nature via the blackboard. Experiments were conducted to provide learners and teachers with a means to interact with each other and later evaluated. Results reveal that a teacher's questions ("scaffolding") of learners to promote feedback was an important factor in enhancing interactivity and improving BMC of typical quiet learners, by using the tool.

This paper explores the issues surrounding the use of an interactive blackboard as a teaching tool. A conceptual computerized learning environment termed "i-room" is proposed as a future technology deliverable, its objective being to provide students and teacher with the means to interact with each other in real time in a variety of ways. Some of the concepts within the "i-room" were used to develop an interactive blackboard that allowed subjects to issue real time feedback, comments, ideas and suggestions using either a web browser or a cellular phone. A class was conducted to evaluate effectiveness of the system. Results revealed almost a student evaluated the feedback functions was effective and the class was interactive when compared with a traditional class. But subject feedback suggests that there are a number of problems associated with the implementation of an interactive blackboard namely the real time feedback causes confusion and that the covert nature of sending feedback may result in improper use.

Today, many electronic Bulletin Board Systems (BBS) are established on the Internet and have been used in many researches of Computer Supported Collaborative Learning (CSCL). And then, in this study, (1) the authors picked up and identified necessary functions and interfaces to exchange ideas. And then (2) the authors developed and evaluated a new electronic Bulletin Board System including the functions and the interfaces described above. In part (1), the authors carried out a research using standard Bulletin Board System displaying time-series. Accordingly, it was identified the necessity for displaying the relation between writings and visualizing user's impression and popularity of the writing. In part (2), the authors developed a system based on the above results. This system displays the writing connection using 3D-tree-structure. In addition, it can visualize the user's impression and popularity using color variation. Then the authors carried out an experiment for the evaluation of this system. It was cleared that visualizing interactions are effective in interchanging ideas. But there is room for improvement in the method of visualizing and user-friendly operationally of this system.
