The benefits of online collaborative learning, sometimes referred to as CSCL (computer-supported collaborative learning) are compelling, but many instructors are loath to experiment with non-conventional methods of teaching and learning because of the perceived problems. This paper reviews the existing literature to present the seven most commonly reported(More)
A case-control study was undertaken to investigate the role of diet in women with breast cancer, and in two groups of women with benign breast disease: epithelial hyperplasia, and fibrocystic disease without hyperplasia. The study provides data which suggest that the consumption of red meat, savoury meals (pizza, pies, stew, etc.) and of starches is(More)
This paper centres on the sense of isolation that online study may engender among learners, a factor often ignored by many educators, but one that may make the difference between a successful and an unsuccessful online learning environment for many students. The importance of a proper appreciation of the learners’ social context is stressed, as is the(More)
Focal hand dystonia (FHd) is a recalcitrant, disabling movement disorder, characterized by involuntary co-contractions of agonists and antagonists, that can develop in patients who overuse or misuse their hands. The aim of this study was to document clinical neuromusculoskeletal performance and somatosensory responses (magnetoencephalography) in healthy(More)
The term “flexible learning’ has been used by many institutions with regard to their methods of course delivery, particularly by those seeking to attract external students. In almost no cases is the use of the term justified, since the flexibility concerned relates only to certain very limited components of the learning process. This paper outlines the very(More)
Collaborative learning is an instructional situation in which students interact while accomplishing an academic task. Collaborative learning as a theory on the whole is not a new idea (Gaillet, 1994), but the concept of computer supported collaborative learning is (Cerratto and Belisle, 1995). But what actually is Computer-Supported Collaborative Learning(More)
“The Hardest Logic Puzzle Ever” was first described by the late George Boolos in the Spring 1996 issue of the Harvard Review of Philosophy. Although not dissimilar in appearance from many other simpler puzzles involving gods (or tribesmen) who always tell the truth or always lie, this puzzle has several features that make the solution far from trivial. This(More)
OBJECTIVE: Many studies of dementia mainly Alzheimer's disease (AD) by using MEG have been reported. Some results show there are some differences between patients and controls in MEG data. But it is still difficult to diagnose the disease in early stage using their methods because of large individual variation. We measured many patients and normal aged(More)
The rush to the use of advanced learning technologies has left many academics dazed and confused. The above excerpt, a direct quotation from a well-respected and admired academic, in many ways prompted the writing of this paper. Why isn’t it much fun any more? What are these new directions currently being explored by many universities, and why are they not(More)
