数学用携帯端末による数学コミュニケーション環境の開発試行研究

抄録

For developing a palmtop environment for mathematics communication on the Internet as the newest mediational means for mathematics and for analyzing how it works, this study developed and improved the BBS sites. Through experiments of BBS sites, some difficulties are clarified from the perspectives of grounding (Baker et al., 1999) and mediational means (Wertsch, 1991) . The difference of BBS's designs strongly influenced the quality of communication. In the pilot study, experiments illustrated that we communicated well on mathematics in the palmtop environment if we are accustomed to it. In the study, the following factors are identified ; Firstly, ways of communication such as asking for better mathematical explanation, asking to check conditions, confirming what the other side is saying, and greetings. Secondly, ways of using the palmtop computer, such as how to use the BBS with the Internet and how to use the DGS.
