摘要

同儕教學的教學方法包含課前學習和課中問答討論學習兩個部分，旨在增加學生在課堂中的投入程度與對課程主題的了解。然而現有支援同儕教學的系統缺乏引導學生進行討論的機制，本研究旨在開發一個系統來輔助同儕教學(Peer Instruction)之進行，特別是研發引導學生進行討論的機制。本研究設計了更換學生座位、系統提供配對者、共同分數計算等引導機制來引導學生進行討論。實驗結果顯示引導機制可以增加學生參與討論的比率。學生問卷的結果也顯示大部分學生認為引導機制有助於討論。另外，現有同儕教學的研究未詳細分析學生進行討論的狀況與影響，本研究藉由兩次實驗觀察學生們進行討論的狀況以及討論活動對學生作答的影響。結果發現學生經過討論後答對率以及自信度都有明顯進步且達顯著差異，而討論後將原本錯誤答案更改為正確答案比例的學生也占相當高的比例，由此可以推測討論活動確實使學生們在進行學習時有正面的影響。若觀察不同答題情況下的同學間討論，其中答題進步分數最明顯的配對情境則為第一次作答答錯與答對的學生互相討論。另外，本研究也發現若討論後被對方說服或是討論後兩人都同意更改為另一答案的情況時，其進步分數最高且討論前後得分差異也最顯著，由此可發現配對討論同學的答題情況的確會影響學生的答題狀況。

Peer Instruction, including pre-reading activity before course and concept test and peer discussion in course, aims to increase students’ engagement and understanding. However, current Peer Instruction studies lack of guiding mechanisms to promote peer discussion. This study aims to develop a Peer Instruction assisted system with discussion guiding mechanisms, including seat exchange, partner pairing, and mutual scoring. The experimental results revealed that the guiding mechanisms increased the percentage of students' participation in discussion. The questionnaire results also showed that most students consider guiding mechanisms helpful for promoting discussion. In addition, this study took two experiments to investigate the effects of partners on the peer discussion. The results revealed that after discussing with each other, the students’ performance and confidence in the concept test are increased. Furthermore, the rate of changing answers from wrong to correct is high. The results confirmed that peer instruction is helpful. This study investigated different discussion situations and discussion outcomes among the students. The results revealed that those students who answered incorrectly in first time have good performance when they discussing with those students who answered correctly. The results also showed that the students who are convinced or they both agree to change to a new answer make the most progress between before and after discussion. These results revealed the impact of discussion partner on discussion in Peer Instruction.
