Peer assessment of teaching can improve the quality of instruction and contribute to summative evaluation of teaching effectiveness integral to high-stakes decision making. There is, however, a paucity of validated, criterion-based peer assessment instruments. The authors describe development and pilot testing of one such instrument and share lessons learned. The report provides a description o...

Forty-eight quantitative peer assessment studies comparing peer and teacher marks were subjected to meta-analysis. Peer assessments were found to resemble more closely teacher assessments when global judgements based on well understood criteria are used rather than when marking involves assessing several individual dimensions. Similarly, peer assessments better resemble faculty assessments when...

OBJECTIVES The objective of this study was to explore whether reducing the material supplied to external experts during peer review and decreasing the burden of response would maintain review quality into prioritising research questions for a major research funder. METHODS AND ANALYSIS Clinical experts who agreed to review documents outlining research for potential commissioning were screened...

The excessive workload generated by the assessment of exam papers in large classes and the need to give feedback in time often constitute a rather heavy burden for teachers. The online peer assessment can contribute to reduce this workload and, possibly, to improve learning quality by assigning the assessment task to students. However, this raises the question of validity. In order to study thi...

Student-directed teaching and assessment techniques are gradually dominating educational systems almost all over the world. This study investigated a cohort of male and female Iranian EFL students’ attitudes toward self-, peer-, and teacher-assessment experiences. Sixty three students at Urmia University and Tabriz Islamic Azad University, in the form of three intact classes, experienced self-,...

This study describes the application of a Web-based portfolio for appreciation and peer assessment for visual-art education in elementary school. Besides examining the effectiveness of the proposed system in enhancing visual art education, this study also addresses how Web-based portfolios can help teachers to assess student learning progress and facilitate peer assessment. The results of quest...

The study proposes an approach to support students' debugging exercise named scaffolding online peer assessment built upon the scaffolding theory. The scaffolding mechanism in this approach includes two aspects. One is that the system provides error tips to aid students in finding errors in their assignments. The other mechanism is the peer’s comment itself which is viewed as a kind of scaffold...

The potential benefits of peer learning have long been recognized and are especially relevant today when lifelong and life-wide learning is prevalent. In this paper, we propose to incorporate peer assessment as part of the learning activities using an on-line environment. Participants are required to conduct group projects which entail an intra -group reflection by critically evaluating their o...

Recommendation-based reputation assessment in peer-to-peer systems relies on recommendations in predicting the reputation of peers. In this paper, we discuss the effectiveness and cost metrics in the recommendation retrieval. We evaluate the following retrieval methods: flooding, recommendation tree, and the storage peer. The simulation results show that overlay network construction significant...
