Conclusion I applaud ISTE, AASL, AECT, and the other organizations involved for tackling the “messy work” of developing standards for
the use of technology and information resources in schools. And, at the same time, I call for a “second generation” of standards
that define realistic expectations for teachers based on the subjects and levels they are called upon to teach. I propose
that professional organizations from each subject work with ISTE and AECT to complete this huge task, and I propose that we
consider as a “next step” the creation of a set of on-line learning experiences through which teachers can gain the identified
skills and knowledge by using the very technologies we’re hoping they’ll embrace in their own teaching.
There’s an old saying, “If you don’t know where you’re going, any road will do.” As far as educational technologies are concerned,
this is also true. For many, the goal seems to have been simply to “get more computers into the schools,” without much thought
about purpose. To return to Phil Schlechty’s metaphor, It’s generally been a brief and misguided “Ready” stage (occupied with
questions like “How many do we need?” “What type?” “Where?” and “How shall we connect them?”), followed by “Fire!” (the acquisition
and installation of equipment). What we need is: “Ready” (the creation of appropriate teams of people who will combine their
insights to plan for the district)... “Aim” (a series of discussions about what technologies can accomplish for schools and
the students they serve)... “Fire” (acquisition, installation, and professional development according to plan)... “Aim” (an
assessment of how well the technologies and related programs met the intended goals, and a new planning effort designed to
close the gap)... “Fire” (acquisition and implementation designed to eliminate the gap)... “Aim” (another gap assessment)...
“Fire” (another attempt to close gaps)..., And so on. 相似文献

Purpose:The aim of the study was to determine whether corticospinal excitability and inhibition of the tibialis anterior during single-leg standing differs among individuals with chronic ankle instability(CAI),lateral ankle sprain copers,and healthy controls.Methods:Twenty-three participants with CAI,23 lateral ankle sprain copers,and 24 healthy control participants volunteered.Active motor threshold(AMT),normalized motor-evoked potential(MEP),and cortical silent period(CSP)were evaluated by transcranial magnetic stimulation while participants performed a single-leg standing task.Results:Participants with CAI had significantly longer CSP at 100%of AMT and lower normalized MEP at 120%of AMT compared to lateral ankle sprain copers(CSP100%:p=0.003;MEP120%:p=0.044)and controls(CSP100%:p=0.041;MEP120%:p=0.006).Conclusion:This investigation demonstrate altered corticospinal excitability and inhibition of the tibialis anterior during single-leg standing in participants with CAI.Further research is needed to examine the effects of corticospinal maladaptations to motor control of the tibial anterior on postural control performance in those with CAI. 相似文献

AbstractIn policy contexts, social exclusion can be experienced through the systematic marginalization of groups by inhibiting their ability to access resources and support. In this article, we consider the context of community sport development in rural Canada to discuss the implications of rationalized policy systems for rural citizens. We discuss instances where engagement with the sport system was constrained as well as the way that rural people responded in order to continue engagement in sport both within and outside of policy frameworks. A more inclusive sport policy system requires the acknowledgement of diverse social outcomes which may be realized through sport. But, in order for this to take place, policy makers and practitioners must acknowledge that these outcomes can exist outside of athlete development and must re-consider the ways that resources and support can be allocated. 相似文献

ABSTRACTThe signing of the Belfast-Good Friday Agreement in 1998 was widely welcomed by those that interpreted it as offering Northern Ireland the prospect of a fresh start, free from inter-ethnic violence that had blighted the country for almost 80 years. Soon it began to be seen by some observers as the genesis too of a ‘Northern Irish’ identity, as the community at large came to reconcile themselves to their common lives in Northern Ireland. Sport was also viewed as offering the prospect of adding weight to this sense of a shared journey and governing bodies of sport unquestionably played their parts in supporting a settled political environment where division had previously existed. This article examines the still contested concept of a ‘Northern Irish’ identity and critically reviews its real currency in a divided society, even if sport and, specifically, association football offers renewed hope for something better in the time ahead. 相似文献
