Abstract

本研究では, 児童のデジタルポートフォリオを数年にわたって蓄積し, それに用いられている語の共起関係から, 入力されたキーワードと関係の強い用語が表示されるデジタルポートフォリオ検索システム「PRIUM」(Portfolio Retrieval for Investigating Useful Material)を開発した.PRIUMを用いて過去のデジタルポートフォリオを検索, 閲覧しながら学習を進めていく授業実践を行ったところ, 過去のデジタルポートフォリオを教材として活用することは, 児童にとって情報のまとめ方が参考になることが分かった.さらに, PRIUMを活用することで, 児童が求めていない情報が載っているデジタルポートフォリオの閲覧数などが減少し, 目的の情報にたどり着きやすくなることが分かった.

This paper describes the development of a digital portfolio retrieval system entitled Portfolio Retrieval for Investigating Useful Material (PRIUM) which reflects keyword similarity. PRIUM was used as an information retrieval tool for an Information Communication Technology (ICT) education class at a primary school. The findings are that elementary school students who used PRIUM could find electronic portfolios they wanted quickly, because PRIUM lessens the need for seeing electronic portfolios they didn't want. In addition, it is clear that electronic portfolios which were made by prior students provide students with useful information even when such electronic portfolios are provided as teaching materials without relying on retrieval systems.
