This paper reports on a case study in which Twitter served as a backchannel to mediate and support the peer-teaching activity in a face-to-face teacher education course. Surveys and interviews were utilised to understand the effectiveness of the Twitter integration and students’ perceived learning in a Twitter-supported peer teaching environment. Tweets were used to determine how preservice tea...

Current search engines with arrays of servers can provide efficient web content services. However, as their returned results are usually enormous mass, finding target information is still time-consuming. To increase the correctness of returned results, different page ranking methods were introduced. Some of them also try to use users’ feedback to increase their precision in ranking. However, as...

Typically, faculty receive feedback about teaching via two mechanisms: end-of-semester student evaluations and peer observation. However, instructors require more sustained encouragement and constructive feedback when implementing evidence-based teaching practices. Our study goal was to characterize the landscape of current instructional-feedback practices in biology and uncover faculty percept...

Instructors use peer feedback to afford students multiple assessments of their work and to help them acquire important lifelong skills. However, research finds that this type of feedback has questionable validity, reliability, and accuracy, and instructors consider much of it too uncritical, superficial, vague, and content-focused, among other things. This article posits that the typical judgme...

From today’s standpoint, it is easy enough to see that the U.S. economy has not been well served by the mortgage lending institutions that became dominant over the past several decades. The financial crisis as a whole seems over-determined in retrospect, it was a “perfect storm.” The debate rages over the appropriate weightings of the candidate causes. In this paper, we focus relatively narrowl...

Peer observation of teaching is seen as a supportive and developmental process for improving the quality of teaching in universities. Evidence is emerging that the process of observing is just as if not more valuable than being observed and given feedback. In this study lecturers completing a Foundations program in university learning and teaching were interviewed about their experience of part...

We have developed EM-trust, a robust algorithm for evaluating reputations in peer-to-peer marketplaces. EM-trust is robust in the sense that it is far less susceptible than are previous algorithms to errors due to inaccurate feedback. Moreover, a Bayesian version of EM-trust seems ideally suited to real peer-to-peer marketplaces, in which participants are unlikely to have had previous interacti...

The study investigates in what ways the combination of self-assessment and collaborative peer assessment can support students’ creativeand critical-abilities, as well as providing opportunities for meta-cognitive learning. The study is informed by sociocultural theories research traditions and computer supported collaborative learning, CSCL. Data were collected from 22 student teachers peer ass...

This study compared four ways of responding to EFL students in writing class to study whether they resulted in different outcomes in term of student‟s errors in writing. A total of 119 intermediate level students were selected as subjects, including students from three English reading and writing classes, and some voluntary participants. The students of three English reading and writing classes...
