Participation in “communities of practice” is often depicted as a central feature of various theoretical understandings of the social nature of learning. How are such communities of practice to be enacted in distance education, which, by definition, implies spatial detachment? This article reflects on the dimensions of communities of practice experienced by four students undertaking doctoral studies by distance education, working in different countries than the one in which the institution of their studies is based, and at four different phases of their doctoral program. In each writer’s experience, community of practice involvement was identified as critical in program completion, yet the source of the learning community was in each case outside of institutional provision. 相似文献

Almost every higher education institution is challenged to develop increasing numbers of staff to teach online or blended modes of learning. The process needs to be rapid, cost-effective and lead directly to practical outcomes. From our experience, we had little time, opportunity or the need to start from scratch, and we chose to adopt and adapt a course that was based on a well-rehearsed and respected pedagogical model. We offer our experience to date as a case study with some extracted principles for others to explore and follow. We discuss the value of contextualization, incremental innovation, and mentoring of online convenors. This article will be of interest to those seeking to provide effective professional development routes for large numbers of staff. 相似文献

We estimate the influence of classmates’ ability characteristics on student achievement in exogenously formed university student groups. The study uses administrative data on undergraduate students at a large selective university in Russia. The presence of high-ability classmates has a significant positive effect on individual grades in key economics and mathematics courses as well as on overall academic performance. While a simple linear-in-means model reveals moderate peer effects, non-linear specifications give strong evidence that students at the top of the ability distribution derive the greatest benefit from high-ability classmates. Less able students are not affected by peers and have no significant influence on peers’ outcomes. 相似文献

Demand-pull, technology-push, and government-led incentives for non-incremental technical change 总被引:4,自引:0,他引:4

Rising expectations about future demand for new technologies increase the incentives for investments in innovation by enlarging payoffs to successful innovations. How well does this notion of “demand-pull” apply to non-incremental technological change when demand is largely attributable to actions by governments? In this case, inventors of the most important inventions did not respond positively to strong demand-pull policies; filing of highly cited patents declined precipitously just as demand for wind power created a multi-billion dollar market. Three explanations for this apparent inconsistency with the demand-pull hypothesis played a role: (1) the rapid convergence on a single dominant design limited the market opportunity for non-incremental technical improvements; (2) even though the policies implemented were stringent enough to stimulate demand, uncertainty in their longevity dampened the incentives for inventions that were likely to take several years to pay off; and (3) alternative explanations, such as declining R&D funding and weakening presidential engagement on energy, appear to have been important. 相似文献

A within‐school evaluation of Schoolwide Early Language and Literacy (SWELL) was undertaken in six disadvantaged schools in NSW in 1995 and 1996 using a sample of Kindergarten students in each school before (control group) and after (experimental group) the implementation of SWELL. As many control and experimental students as could be accessed were tested on four different early literacy measures when they were mid‐way through Year 1. Assessment at the end of the Kindergarten year and mid‐way through Year 1 indicated that experimental students significantly outperformed their control counterparts on tests measuring pseudoword decoding and reading connected text at the end of Kindergarten, and on tests measuring pseudoword decoding, reading connected text, invented spelling, and a standardised reading measure mid‐way through Year 1. 相似文献

Improving the quality and effectiveness of computer-mediated instruction through usability evaluations 总被引:1,自引:0,他引:1

Brigham Young University's Center for Instructional Design (CID) creates online courses and multimedia instructional applications for university faculty. This paper asserts that including usability testing as a part of evaluation improves the quality and effectiveness of computer‐mediated instruction. The paper describes the fundamental purpose and functions of usability testing, and also distinguishes between different forms of evaluation: accessibility, quality assurance (QA), usability and implementation. Through a detailed case study, we describe how usability testing improved the quality of a computer‐based chemistry course and facilitated a clearer analysis of the learning effectiveness of this course. 相似文献

Music is recognized as an effective mode of teaching young children but is rarely used in university-level science courses. This article reviews the somewhat limited evidence on whether and how content-rich music might affect college students' understanding of science and offers practical suggestions for incorporating music into courses. Aside from aiding memorization, songs may potentially improve learning by helping students feel relaxed and welcome in stressful settings, engaging students through multiple modes (verbal vs. nonverbal) and modalities (auditory vs. visual vs. kinesthetic) simultaneously, challenging students to integrate and "own" the material through the medium of song lyrics, and increasing students' time on task outside of class through enjoyable listening or songwriting assignments. Students may produce content-rich songs of good quality if given sufficient assistance and encouragement by instructors and peers. The challenges ahead include 1) defining the circumstances in which music is most likely to promote learning and 2) developing rubrics for evaluating the quality of songs. 相似文献
