摘要

本研究運用Moodle平台設計結構化的微型教學輔助模組，探討微型教學活動中採用不同網路同儕評量方式對同儕評分效度、評分結果、教學表現以及評論品質的影響，並以問卷調查方式了解實施成效，以作為日後改進之參考。
　　本研究採等組後測實驗設計，以臺北市某大學四年級修讀國民小學教學實習的29位學生為受試者，隨機分派至實驗組「協同評量組」及控制組「個別評量組」，兩組同學皆需將試教與正式教學二個階段的教學錄影上傳至Moodle網路學習平台，並依所屬組別進行同儕評分與評論。
　　實驗後以敘述統計、皮爾森積差相關、t檢定與卡方檢定分析二組同儕互評的結果，研究發現如下：
一、二組的評分結果皆與教師評分結果達顯著的中度正相關，同儕評分具效度。
二、正式教學的同儕評分結果協同評量組顯著高於個別評量組，教師評分結果協同評量組雖高於個別評量組，但未達顯著差異。
三、協同評量組撰寫評論的投入程度較高且評論屬性多為具體的肯定與建議類別，評論品質較佳，而二組的評論項目皆集中於表達呈現類別。
四、二組受試者皆肯定系統的功能以及對改進教學的幫助，並願意推薦學弟妹使用。

The purpose of this study was to design a structured microteaching module on Moodle to examine the effects of validity and results of peer assessment, teaching performance and comment quality by using different web-based peer assessment methods in microteaching activities. Furthermore, questionnaires were used to understand the effects of its implementation which also can do as references for future improvements.
A posttest-only control group experimental design was used in this study. The subjects were 29 fourth grade undergraduates in Taipei City. They were randomly assigned to experimental group "collaborative assessment group (CAG)" and control group "individual assessment group (IAG)". All of participants were asked to upload their trial and formal teaching videos to Moodle, and then scored peers’ performance and comment according their group.
After the experiment, descriptive statistics, Pearson's product-moment correlation, t-test, and chi-square test were used to analyze the datum. Results of this study were concluded as following:
1.Both groups’ rating results had validity.
2.In formal teaching period, CAG get significantly higher scores than IAG, but the supervisors' rating results released that there was no significant difference.
3.CAG had better comment quality than IAG, while both groups focused on presentation factor.
4.Most of participants recognized the function of this system and agreed it’s helpful to improving teaching. They were also willing to recommend it to juniors.
