This paper reports the results and insights ofan exploratory investigation of theeffectiveness of a prototypic virtualproblem-based learning (VPBL) exercisedelivered via the WWW, that uses HypermediaAssisted Instructional Technologies (HAIT). The study targeted all first year medicalstudents at a south-central University Schoolof Medicine who were enrolled in the humanphysiology course during the Spring 2000 (n =150). A quasi-experimental, post-test onlyresearch design compared the VPBL and atext-based version of the same PBL exercise onstudents' achievement, as measured by a set ofselected physiology examination items, andtheir perceptions of the learning environment,as measured by the Teaching and LearningEnvironment Questionnaire (TLEQ) (Chauvin &Bowdish, 1998). Findings suggest that the VPBLis equally as effective as the text-basedversion for enhancing students' learning andtheir learning environment in small group, PBLsessions. In this paper, we examine theevidence supporting the VPBL innovation andexplore what constitutes necessary andsufficient evidence that an educationalinnovation should be incorporated appropriatelyinto the medical educational practice of aschool. We examine instructional design issuessuch as learner control, instructional control,and teacher and learner roles as related toinstructional development for the WWW, bycomparing and contrasting our observations ofthe VPBL design experiment with theprofessional literature. 相似文献

A cultural map of the United Kingdom, 2003 总被引:1,自引:0,他引:1
This paper employs Multiple Correspondence Analysis (MCA) to map cultural participation and taste in the UK. It constructs what Bourdieu calls a space of lifestyles from evidence collected in a national random sample survey of the British population in 2003. MCA constructs the space relationally on the basis of similarities and differences in responses to questions about a large number of cultural items in several sub‐fields including music, reading, TV and recreational activity. These items are mapped along two axes and their clustering indicates affinities between tastes and practices across sub‐fields. The cultural patterns are described. We then superimpose socio‐demographic variables, including class, educational qualifications and age, the distribution of which indicates tendencies for certain categories of person to have shared tastes. The analysis reveals meaningful, socially differentiated patterns of taste. The space of lifestyles proves to be structured primarily by the total volume of capital (resources) held by respondents and by age. Strong oppositions are revealed. An older, educated middle class shares ‘legitimate’ established cultural preferences. The repertoire of a younger middle class group contains more contemporary and ‘popular’ items. Less well‐educated, working class groups are characterised often primarily by lack of cultural participation, but also, especially among the young, by an aversion to ‘legitimate’ culture. 相似文献

All in a knot of one another's labours: self-determination,network organising and learning 总被引:1,自引:1,他引:0
Mike Pedler 《Action Learning: Research and Practice》2012,9(1):5-28
This essay is about how to learn to organise to tackle the intractable and most difficult problems of organisations and societies. It opens with a discussion of the nature of such problems, which are the spur for Revans' action learning and the focus of some recent thinking on leadership. Action learning works on the basis of peer relationships and self-determination lends itself naturally to attempts to organise in networks rather than in hierarchies. Taking cancer care as an example of an intractable problem, the centre point of the essay is a case study of an NHS Cancer Network which shows the complex dependencies and connections of this way of working. Although the recent history of organising has been summed up as a trajectory ‘from hierarchies to networks’, I argue that our capabilities with the intractable and wicked problems are limited by our dependence upon hierarchical models of organising and also by management practices that are best suited to ‘tame’ problems and a management education tradition that produces ‘subalterns’ rather than self-determining actors. These points are made via an excursion through three philosophies of freedom: post-colonialism, anarchism and Quakerism. These ideas reveal the cultural legacies to be overcome in the quest to learn how to organise with free actors. The triple practices of action learning, distributed leadership and network organising are offered as being part of the solution. 相似文献

OBJECTIVE: To identify reliable, inexpensive predictors of foster care placement disruption that could be used to assess risk of placement failure. METHODS: Using the Parent Daily Report Checklist (PDR), foster or kinship parents of 246 children (5-12 years old) in California were interviewed three times about whether or not their foster child engaged in any of the 30 problem behaviors during the previous 24 h. PDR was conducted during telephone contacts (5-10 min each) that occurred from 1 to 3 days apart at baseline. Disruptions were tracked for the subsequent 12 months. Other potential predictors of disruption were examined, including the child's age, gender, and ethnicity, the foster parent's ethnicity, the number of other children in the foster home, and the type of placement (kin or non-kin). RESULTS: Foster/kin parents reported an average of 5.77 child problems per day on the PDR checklist. The number of problem behaviors was linearly related to the child's risk of placement disruption during the subsequent year. The threshold for the number of problem behaviors per day that foster and kinship parents tolerated without increased risk of placement disruption for these latency-aged children was 6 or fewer. Children in non-kin placements were more likely to disrupt than those in kinship placements. There was a trend for increased risk of disruption as the number of children in the home increased. CONCLUSIONS: The PDR Checklist may be useful in predicting which placements are at most risk of future disruption, allowing for targeted services and supports. 相似文献
