浮躁国度:我等不及你读完呢

这是学习小提示:为了增加写作效果,作者运用了不少省略了句子成分的短句,阅读时请注意。相信每个人都有过这样的经历--在食堂要排队打饭,公车到站也要排队上车,去过上海世博会的同学想必一提起排队就愤怒。是的,我们似乎变得越来越急躁,对等感到越发不耐烦--也许有些人还没看完这段话就已经跳到正文咯--     

The Promise of University-Assisted Community Schools to Transform American Schooling: A Report From the Field, 1985–2012

This article explores the university-assisted community school approach as it has been developed at the University of Pennsylvania with its school and community partners in West Philadelphia since 1985, as well as adapted nationally. The approach is grounded in John Dewey's theory that the neighborhood school can function as the core neighborhood institution that provides comprehensive services, galvanizes other community institutions and groups, and helps solve the myriad problems schools and community confront in a rapidly changing world. Building on Dewey's ideas, the authors argue that all colleges and universities should make solving the problem of the American schooling system a very high institutional priority; their contributions to its solution should count heavily both in assessing their institutional performance (by themselves and others) and be a critical factor when responding to their requests for renewed or increased resources and financial support. Providing concrete examples from over 20 years of work in West Philadelphia, as well as from initiatives across the country, this article explores the potential of developing university-assisted community schools as an effective approach for school reform, pre-Kindergarten through higher education.     

A comparison of modeling modalities in the observational learning of an externally paced skill.

This study contrasted prepractice modeling with either the perceptual component (perceptual modeling) or the motor component (movement pattern) of a coincident-timing task to determine whether experiencing the modalities singly or in combination enhanced timing performance on initiation of active practice. The motor component was a 60-cm right-to-left arm movement coincident with the illumination of lights on a Bassin timer runway to displace a barrier as the final runway light was illuminated. Four groups were compared (n = 12 per group). A perceptual modeling group passively viewed stimulus runway lights prior to attempting the task. A motoric modeling group viewed a videotape prior to practice of a model performing the motor component of the skill with zero timing error. A perceptual modeling plus motoric modeling group experienced both modeling modalities prior to performance. Finally, a no modeling group simply initiated practice on the task without modeling. Results indicated that the groups experiencing perceptual modeling initiated practice with significantly less average timing error and variability. Thus, perceptual modeling appeared to be at least as important as motoric modeling as a source of prepractice information to make available to a learner to optimize coincident-timing skill acquisition.
