課程中，老師透過循環讓詞語的學習更好；課程後，學習者必須透過複習再鞏固(consolidating)詞彙。從(Schmitt, 2000; 131) 的遺忘軌跡來看，在課程學習後馬上複習是最好的時間，然後隨著時間前進會隨著遺忘而留下的記憶會越來越少。 (Russell, 1979; 149) 建議在學習後的五到十分鐘、二十四小時、一個星期、一個月和六個月後進行複習，是一個可用來作為鞏固記憶、按表操課的時間。如此，遺忘的可能性會大幅地減低。
除了複習外，另一個方式就是將新的知識和舊有的知識連接在一塊兒。Hulstijn (1997) 的關鍵字方法就是如此。另外一個是將新的詞語和舊的語詞放在同一個組別(group)裡，由於舊的詞語已經穩固地在心裡了，所以會提供一個好像鉤子的東西，把新詞語鉤在一塊。雖然這樣分組有好處，但是如果同時將兩個新的詞語一起學習的話，有可能會造成混淆的連結(crossassociation)。
