A core educational goal is to produce self-directed lifelong learners who have acquired or are able to acquire the knowledge and skills necessary for their future professional workplace in a networked world. Constructivist and socio-constructivist theories of learning and instruction recommend using collaborative learning scenarios in all kinds of educational contexts in order to attain this go...

Research in L1 writing has found numerous benefits of employing collaborative learning in the classroom. The research findings on group work provide clear evidence that engaging learners in group activities increases opportunities for students to engage in the negotiation of meaning, which further leads to better acquisition. The present study, implementing two different collaborative feedback ...

This preliminary classroom study aims to examine the impact of trained responders’ feedback on EFL college students’ revisions, both in terms of revision types and quality. After a 4-hour in-class demonstration and a 1-hour after-class reviewer-teacher conference with each student (n = 18), the instructor/researcher collected students’ first drafts and revisions, as well as reviewers’ written f...

Peer-to-Peer data structures (P2P data structures) let a large number of anonymous peers share the data-management workload. A common assumption behind such systems is that peers behave cooperatively. But as with many distributed systems where participation is voluntary, and the participants are not clearly observable, unreliable behavior is the dominant strategy. This calls for reputation syst...

Content-Addressable Networks (CAN) manage huge sets of (key, value)-pairs and cope with very high workloads. They follow the peer-to-peer paradigm: They consist of nodes that are autonomous. This means that peers may be uncooperative, i.e., not carrying out their share of the work while trying to benefit from the network. This article deals with this kind of adverse behavior in CAN, e.g., not a...

BACKGROUND Although it is often criticised, the lecture remains a fundamental part of medical training because it is an economical and efficient method for teaching both factual and experimental knowledge. However, if administered incorrectly, it can be boring and useless. Feedback from peers is increasingly recognized as an effective method of encouraging self-reflection and continuing profess...

This study examined reciprocal associations among adolescents' negative feedback-seeking, depressive symptoms, perceptions of friendship quality, and peer-reported social preference over an 11-month period. A total of 478 adolescents in grades 6-8 completed measures of negative feedback-seeking, depressive symptoms, friendship quality, global-self-esteem, and social anxiety at two time points. ...

Revision is a core writing skill that presents challenges to both novice and expert writers. Within the context of peer review, peer feedback has the potential to provide rich guidance for reviewing, especially when making content-level changes. However, authors must review and evaluate each piece of feedback for meaningful critiques that can be applied to further drafts. In this work, we analy...
