本研究旨在探討線上同儕評量及績效回饋、改正回饋對國中學生簡報製作技能學習成效的影響。研究樣本為國民中學二年級兩班62位學生。在教學實驗中,依評量方式及回饋方式,分為同儕評量-績效回饋組、同儕評量-改正回饋組、教師評量-績效回饋組及教師評量-改正回饋組等四組。研究結果發現(1)評量方式對國中學生簡報製作技能學習成效沒有顯著影響;(2)評量方式與回饋方式之交互作用對國中學生簡報製作技能學習成效沒有顯著影響;(3)回饋方式對國中學生簡報製作技能學習成效有顯著影響-改正回饋優於績效回饋;(4)大多數的學生可以接受同儕評量;(5)大多數的學生認為同儕評量是公平的,但有部份人但仍懷疑同儕評量的公平性及同儕評量可以評得和老師評量一樣好;(6)同儕評量在評分上範圍比較小。
The purpose of this study was to investigate the effects of on-line peer assessment and feedback (performance feedback vs. corrected feedback) on junior high students’ PowerPoint learning performance and attitudes. The samples of this study are 62 studennts in two classes. The subject were assigned to one of the four experiment groups: peer assessment - performance feedback group, peer assessment - corrected feedback group, staff assessment - performance feedback group, staff assessment - corrected feedback group.The result show that: (1)there was no significantly difference between the peer assessment and staff assessment on learning PowerPoint is not signal, (2) there was no significantly difference among the corelation between various assessment and various feedback on learning PowerPoint , (3) there was significantly difference between the corrected feedback and performance feedback, the corrected feedback group was significantly better than performance feedback group, (4)the method of peer assessment is acceptable by students, (5)peer can assess fairly, but someone doubts the fariness (6)the students gave a narrower range of marks than the teacher.
