Abstract

This is a ‘view from the coalface’ of someone who runs a large company responsible for the training of other member companies of the Group of which it forms a part. He gives examples from the day‐to‐day work of his company, and looks to the future of open and distance learning in the industrial world.  相似文献

Attention disorders in the school population include attention deficit, hyperactivity and conduct disorders. A key concept for distinguishing hyperactive from attention disorders is behavioural inhibition as advocated by Barkley, a prominent American researcher. However, the concept itself needs to be understood because, as argued in this paper, there are two kinds of inhibition: Pavlov's original concept and the American one. These should be differentiated if the abnormal conditions associated with attention and hyperactivity are to be rationally connected to cognitive characteristics, rather than to be solely based on clinical symptoms and behavioural ratings. We suggest a consensus on the concept of inhibition and a unified view of attention disorders integrating cognitive and behavioural manifestations. Finally, the importance of basing remediation on a theoretically supported and rationally derived set of cognitive training tasks for the amelioration of inattention and hyperactivity is offered.  相似文献

Abstract

Students develop robust mental models of teaching and learning during their school years, and as such, often teach as they were taught—possibly perpetuating practices that limit intellectual inquiry in classrooms. This paper reports on an analysis, using a conceptual framework and NUD?1ST software, of a cohort of 3rd‐year teacher education students' reflections on changes in their mental models following their experiences in a problem‐based learning (PBL) topic. Results provide evidence that students do report changing mental models in areas such as (a) the value of case studies for engaging with subject content, motivating learning, and connecting theory with practice; (b) self‐reflection and peer collaboration for cognitive and professional growth; and (c) processes of inquiry for developing self‐regulated learning practices.  相似文献
