Outline of Final Research Achievements

We constructed a skin conductance and heart rate measurement system tailored for classroom use, incorporating open-source assets to minimize financial and human costs. In six STEM education sessions, practical exercises such as measurement and assembly yielded more positive subjective evaluations compared to lecture sessions. The evaluations of "unpleasant-pleasant," "vigor," and "concentration" demonstrated a relatively strong correlation with physiological responses. Regardless of the class format, higher physiological responses appeared to reflect the students' sense of pleasantness. Students with higher vigor ratings maintained relatively high alertness even in the latter parts of the class, where alertness typically tends to decrease. The concentration rating was solely related to skin conductance, suggesting that assessing concentration through heart rate alone may be challenging.

Academic Significance and Societal Importance of the Research Achievements

本研究は，オープンソース資産の導入により，金銭的・人的に低コストで，授業中の受講者の生理反応測定を可能とした。さらに，STEM教育を対象とした実測では，講義において覚醒が低下しやすい参加者が存在すること，皮膚コンダクタンスが授業に対する快-不快評価や活気，集中を反映する可能性，心拍数による集中評価が困難である可能性が示された。これらの結果は，従来知識やスキルに偏りがちであった授業評価に，態度やモチベーションの評価を加え，参加者の特質に応じたカリキュラム提供の可能性を開くものである。
