Beyond media stickiness and cognitive imprinting: Rethinking creativity in cooperative work &; learning with ICTs

This paper attempts to build a bridge between the fields of Computer Supported Cooperative Work and learning in online communities. A framework for group interactions is presented contrasting creative interactions such as collaboration with other but still valuable interaction types. Evaluative tools are proposed capable of identifying particular learning processes associated with various interactive activities. Each field has independently developed notions of inertia in the behaviour of users of these technologies. The notion of media stickiness is examined and related to that of imprinting in learning communities. However, dynamic and creative tracks can also be discerned and the argument is made that true collaboration requires attention to learning processes. Various suggestions are made of value to both fields and further research identified.     

Training early childhood teachers for sustainability: towards a ‘learning experience of a different kind’

In this study, we discuss findings from a small-scale project evaluating an in-service teacher training programme focused on ‘perspective transformation’ in early childhood education and education for sustainability (EfS). A bespoke professional development programme was developed for Turkish early childhood teachers, based on a variety of Mezirowian-inspired adult education activities. Data were gathered using a mixed method research design, from 24 early childhood educators, through learning diaries, a Learning Activities Survey and follow-up interviews. Initial findings illustrate the range of transformations possible in the teachers’ perspectives during and after the training workshops. Influential factors in facilitating perspective transformation are shown to be the content, structure and sequencing of the training, and peer support. We conclude that transformative learning techniques offer a viable framework for engaging practicing early childhood teachers with EfS and also discuss implications for teacher preparation in both areas.     

An action learning approach to the question: are ambulance response time targets achievable?

In recent years, NHS Ambulance Trusts throughout the UK have consistently failed to achieve their response time targets for both actual and potential life-threatening calls. To avoid a media and public outcry, the NHS response has been to change the basic parameters upon which the response time targets are calculated. An action learning study, which considered patient experience from initial response to outcome, concluded that the ambulance service must move away from the nearest crew response model to one which provides a defined multi-organisational service to specific categories of need. A key issue with the learning sets, which were made up of front-line crews, was understanding the Trust-wide picture and where acceptable new procedures could provide economic benefits to the Trust, benefits to the patients and help achieve the response time targets. A simulation model driven by parameters agreed by the action learning sets provided proof that new procedures would generate the required benefits. The learning sets also identified that the public should adjust their expectations to understanding that an immediate front-line ambulance response would only be despatched in life-threatening cases, but there would be alternative slower responses for all other cases.     

Community‐Based Educational Planning for Severely Handicapped Students: An Expanding Role for Teachers∗

The emphasis on deinstitutionalization in recent years has resulted in a substantial increase in the use of small community-based residential facilities for disabled students; concomitantry there has been a shift towards a developmental or functional model for instructing these students. These initiatives have resulted in changes in the educational system and in the roles of teachers. Instructional planning for disabled students can no longer be viewed simply within the constraints of the classroom; rather a functional curriculum must be developed which provides for the learning and practising of skills across environments, including residences. Educators must fully participate with parents and residential staff to ensure the coordination of children's habilitation programs; without this involvement, crucial elements may be overlooked. In this paper a model is presented which describes how educators can participate in the planning of programs for severely disabled students in community-based residences. Steps in the process involve assessment of current skills and deficits, evaluation of the type and quality of services children are currently receiving, development of goals, identification and analysis of community resources, specification of individual objectives, monitoring of progress, and evaluation of overall service provision.

     

The response of higher education to older adults: A federal perspective

This article examines and describes the responses of higher education institutions in meeting the needs of older people. Specifically, the article describes the concern of the Federal Council on the Aging for increased educational offerings for older people at American universities and colleges. It provides an overview of the demographic factors creating a graying society, discusses the challenge that aging presents to higher education, and cites, with examples, steps to be taken by higher education institutions to directly or indirectly benefit older persons.     

The Impact of Science Fiction Film on Student Understanding of Science

Researchers who have investigated the public understanding of science have argued that fictional cinema and television has proven to be particularly effective at blurring the distinction between fact and fiction. The rationale for this study lies in the notion that to teach science effectively, educators need to understand how popular culture influences their students’ perception and understanding of science. Using naturalistic research methods in a diverse middle school we found that students who watched a popular science fiction film, The Core, had a number of misunderstandings of earth science concepts when compared to students who did not watch the movie. We found that a single viewing of a science fiction film can negatively impact student ideas regarding scientific phenomena. Specifically, we found that the film leveraged the scientific authority of the main character, coupled with scientifically correct explanations of some basic earth science, to create a series of plausible, albeit unscientific, ideas that made sense to students.
