摘要

本研究探討提問式教學支援系統(QBISS)之同儕互評及學生學習成效。觀察學生在QBISS進行問題互評及答案互評之情況，探討學生的互評分數與學生學習成效之關係，探討學生對同儕問題及答案之互評品質，及了解學生對線上互評的態度。
本研究進行了兩次準實驗（課堂組及課後組），課堂組的參與者為高商進修部資?處?科三?級36名學生，實驗期間三週，教學時?為九節，結束後進行問卷調查學生對使用QBISS進行同儕互評的看法。課後組的參與者為高商商業經營科一?級50名學生，實驗期間八週，教學時?為十六節，結束後亦進行問卷調查學生使用QBISS進行線上同儕互評的態度。
課堂組的研究結果為：(1)55.56%的問題未做評價，25.23%的答案未做評價。學生認為同儕的問題較不具品質，但認為同儕的提問能引起後續討論的興趣，且認為同儕的答案具備一定之品質。學生很少因為同儕評價問答次數多寡而改進自己的問答。(2)參與評價較多的學生成績不一定較佳。只在「資訊安全」單元，參與答案評價較多的學生小考成績較高。學生提問及回答之優劣與考試成績無顯著相關。(3)學生認為互評的時間不夠。
課後組的研究結果為：(1)1.76%個問題未評價，1.06%個答案未評價，顯示學生積極參與同儕互評。對同儕的問答認同，肯定對自己學習的助益。學生在記憶單元中評價同儕問題的次數越多越能提升自己提問的重要性與對同儕學習的幫助性。(2)整體評價問答的次數與學科學習成效未發現顯著相關，低成就者似較不願參與問答的評鑑。(3)只有CPU和主機構造及週邊設備與輔助記憶體單元,評價問題次數多寡與學科學習成效有顯著相關。而答案評價次數多寡與學科學習成效上只有在記憶單元中發現顯著相關。(4)問題獲得的分數與學科學習成效無顯著相關，低成就者似較不願修正問題。(5)答案獲得的分數與學科學習成效上無顯著相關，然而學生對答案的評審有很高的一致性。(6)學生認為互評是公平的、肯定同儕給自己「答案」的分數有助於改進下一次的回答、會特別將得分高的問答視為課程重點、並表示認真投入同儕互評。(7)學生表示不是很在乎同儕給予「問題」的分數、因此不會改進自己的問題、不會特別去觀摩分數高的楷模問答以改進自己的問答、不會為了互評活動特別認真準備問題與答案。此外學生反應互評活動有趣好玩，是個不錯的學習方式。

The purpose of this study was to explore the effects of students’ peer assessment on learning outcomes in a Questioning-Based Instructional Support System. The research issues to be addressed were student’s question assessment and answer assessment in QBISS, the relationship between peer assessment and learning outcomes, student’s assessment quality and students’ attitude toward peer assessment. The study implemented two experiments, in-class experiment and after-class experiment rspectively.Both quasi-experiments were implemented at two independent vocational high schools. The in-class participants were 36 students. The after-class participants were 50 students.
There are three findings in the in-class experiment. (1) There are 55.56% questions and 25.23% answers have not been assessed. Students think peer’s questions don’t have good quality, but can bring interest to the follow-up discussion. There is no significant difference on the quality of student’s questions and answers and the frequency of assessment. (2) There is no significant difference on the frequency of assessment and the achievement test score except for the information security unit. There is no significant difference on the quality of student’s questions, answers and the achievement test score. (3) Students think they don’t have enough time to assess peer’s questions and answers.
There are seven findings in the after-class experiment. (1) There are only 1.76% questions and 1.06% answers have not been assessed. It showed that students took part in peer assessment actively. Students have positive perceptions toward peer’s questions and answers. Peer’s questions and answers can promote students’ learning. (2)Although there is no significant difference on the frequency of assessment and the achievement test score, we found that low achievers seem have no interest to assess peer’s questions and answers. (3) There is significant difference on the frequency of assessment and the achievement test score in some units. (4) Although there is no significant difference on the achievement test score and the question score which student received from their classmates, we found that low achievers seem have no interest to modify their own questions even they got low score. (5) There is no significant difference on the achievement test score and the answer score which student received from their classmates. (6) Students thouht peer assessment is fair and they confirmed that peer’s score to their “answers” could help them improve their following answers. They will focus on high score questions and answers and seriously take part in the peer assessment. (7) Students think they don’t care about peer’s score to their “questions”. So, they won’t improve their next question. They won’t look high score questions and answers on purposely. Students think peer assessment is an interesting, funny and effective way to learn.
