Fully online courses are becoming progressively more popular because of their “anytime anywhere” learning flexibility. One of the ways students interact with each other and with the instructors within fully online learning environments is via asynchronous discussion forums. However, student engagement in online discussion forums does not always take place automatically and there is a lack of clarity about the ideal role of the instructors in them. In this article, we report on our research on the quality of discussion in fully online courses through analysis of discussion forum activities. We have conducted our research on two large fully online subjects for computing students over two consecutive semesters and used a grounded theoretic approach for data analysis. Our results reveal what students and instructors consider as quality interaction in fully online courses. We also propose two frameworks based on our findings that can be used to ensure effective online interaction. 相似文献

Is the National Numeracy Strategy Research-based? 总被引:1,自引:0,他引:1
Margaret Brown Mike Askew Dave Baker Hazel Denvir & Alison Millett 《British Journal of Educational Studies》1998,46(4):362-385
The British Government has recently agreed proposals for a National Numeracy Strategy which claims to be based on evidence concerning 'hat works'. This article reviews the literature in each key area in which recommendations are made, and makes a judgement of whether the claim is justified. In some areas (e.g. calculators) the recommendations run counter to the evidence. 相似文献

ABSTRACT This article explores practices of representation and role stabilization in an emerging innovation ecosystem in Beirut, Lebanon. With little local track record of software startup activity, any overt practices of venture or business process representation were of immediate utility. The two moments explored, a pitch session at a mentorship committee meeting and a startup founding competition, capture parts of the nascent topology of a venture development setting in the making. In both, pitches for software products were at the heart of the productive process, and this paper argues that these moments of performative representation were not surplus to the process of founding a startup, but rather are crucial productive elements in themselves. Early-stage software development consists of a constant oscillation between making and modeling. The interdependence of writing software code, stabilizing social platforms for work and industry development, and finding specialists who could relate these tasks was crucial to the development of this business ecosystem in Lebanon. It was a system in motion, built of code and confidence. The circulation of information crucial to decision making within a single project required distinct practices of publicity, which in turn required articulatory platforms. 相似文献
