甚麼是「倒流效應/回沖效應 (Backwash Effect/Washback Effect)」?

The term “backwash” is defined as the direct and indirect effects of examinations on teaching methods. This concept was developed into 15 hypotheses by Alderson & Wall and the first two of these :“A test will influence teaching” and “A test will influence learning” are tested via questionnaire-based survey.

Tests have a powerful 'backwash' effect. Tests are taken at the end of a course, so the way they are designed and the test items they contain will influence the way that the teaching takes place up to the time the tests are administered.

The backwash of tests can have a negative (負面) effect on what happens in classrooms, but it can also be very positive (正面). If the test is well-designed, its influence over teaching practice can be extremely beneficial. Most important is what is really being tested, and exactly how the test is constructed to meet that aim.

簡單而言,所謂「倒流效應」就是考試領導教學效應,是指考試對學生學習及教師教學的影響。

Q:何謂回沖效應(Backwash effect)?

A:
它也可稱做反撥作用
簡單來說 ~
它是語言測驗對教學的一種作用反應的影響.

★回沖效應(反撥作用)backwash effect:
測驗對教學的影響稱為回沖或反撥作用,
回沖作用有正面的亦有負面的
藉由編寫試題者以正向積極的態度
看待教學與考試的關係
並且可依據教學目標能力指標來命題,
應可將回沖反撥作用的負面作用減至最低.

==========================================
※補充一點:
另一個也蠻常的使用的參考看看

倒流效應Washback Effect:
「倒流效應」就是考試領導教學效應
→ 是指考試對學生學習及教師教學的影響囉^^
