授業で用いる代表的な用語を，授業の開始時にどの程度知っていたか／終了時にどの程度知ったかを，それぞれ４段階の数値で受講生に回答してもらいました．（回答は評価の対象にしないことを伝えてあります．）
知識レベル：
0＝知らない
1＝用語だけは知っている
2＝内容を少しは知っている
3＝内容を知っている
同一回答者 88 人について，22 の用語に対する授業終了時の知識レベル (0〜3) と授業開始時の知識レベルとの差（最大値は 3）を集計したのが，下表です．
用語： 「(22) 時系列」を除いた各用語の知識レベルの差の平均値は 0.7 以上 であり，全用語の 平均値は 1.3 でした．
受講生： 受講生の平均値は 0.6 以上 が 92% であり，全体の 平均値は 1.3 でした．
欠点： 次の２点は，あらかじめご了解ください．
(1) 受講者の申告に基づいているので，データの客観性と統一性はない．
(2) 知識だけ（しかも少数の用語だけ）の調査である．

表中の空欄は，授業開始時または授業終了時の回答が空欄であって差が計算ができなかったことを示しています（平均値の計算には含めていません）．
差がマイナスである欄は，授業開始時と授業終了時とで回答者の基準がぶれているか，知っているつもりだった用語を実は知らないことが受講中に分かったかのどちらかでしょう．
