So Andrew and his students went in, looked at some of those assignments, understood the root cause of the misconception, and then they produced a targeted error message that would be provided to every student whose answer fell into that bucket, which means that students who made that same mistake would now get personalized feedback telling them how to fix their misconception much more effectively.
それでアンドリューと学生たちは このような課題を調べて 勘違いの原因を突き止めました そして学生が それと 同じ間違いをしたときに エラーメッセージを 出すようにしました だから学生は この勘違いに対して 専用のフィードバックを受け より効果的に 勘違いを解消できます
