Automated Essay Scoring Effect on Test Equating Errors in Mixed-format Test
International Journal of Assessment Tools in Education, 2021 Scoring constructed-response items can be highly difficult, time-consuming, and costly in practice. Improvements in computer technology have enabled automated scoring of constructed-response items. However, the application of automated scoring without an

評価者特性パラメータを付与した項目反応モデルに基づくパフォーマンス・テストの等化精度 [PDF]
, 2018 近年，受験者の実践的かつ高次の能力を測定する手法の一つとしてパフォーマンス評価が注目されている．一方で，パフォーマンス評価の問題として，能力測定の精度が評価者とパフォーマンス課題の特性に強く依存する点が指摘されてきた．この問題を解決する手法として，近年，評価者と課題の特性を表すパラメータを付与した項目反応モデルが多数提案され，その有効性が示されている．他方，現実の評価場面では，複数回の異なるパフォーマンステストの結果を比較するニーズがしばしば生じる．このような場合に項目反応モデルを適用するためには ...
