この研究は，口頭発表活動に必要な技術を身につける実践を通じて，発話力の伸びを検証することを目的とした実証的研究である。高校１年生の実験クラスを対象に，物語の紹介を目的とする，パターン化された構成で行うプレゼンテーション形式の活動を一定期間行い，ポストテストにおける発話を統制クラスと比較した結果，流暢さの面で向上が見られた。実験クラスの経験した発表活動では，パターン化された情報構造で発話内容を考えるため，活動時の発話過程において，概念化の段階で受ける認知的負荷が軽減され，言語化に向ける認知資源を増やすことができ，流暢さが高まったと考えられる。

The present study takes an empirical approach to assessing the effect of speaking practice designed to improve presentation skills. First-year high-school students repeatedly engaged in book-talk activities for a certain period of time. During the activities, they were given a speaking format to facilitate their performance. At the end of the instruction period, students’ speaking fluency was measured, analyzed, and compared with that of a control group. The comparative analysis demonstrates that the students’ fluency improves substantially when they are provided with a speaking format. The result supports the hypothesis that this format helps to lessen the students’ cognitive load at the initial conceptualization stage and instead helps to save cognitive resources for successive stages of speech production, which consequently enhances the students’ speaking performance.
