Imagine the challenge of being immersed in a dynamic learning network where you play brinkmanship with being overwhelmed by a plethora of information, comments, and conversations on a topic of intense interest to you. Through adept facilitation, the comments and encouragement of fellow participants, and your own perseverance, you develop a network of personal connections which serve as metaphorical flying buttresses creating enough stability that you are able to learn in a new, yet profoundly meaningful way – the connectivist massive open online course (cMOOC) way. Through the lens of autoethnography, five seasoned educators collaboratively reflect on their motivation for participating in their initial cMOOC. They analyze their lived experience, what they found most engaging, and most importantly, they grapple with why cMOOC communities often endure past official end-dates. This article attempts to provide insight into the thrill and depth of learning and connection possible through participation in cMOOCs.  相似文献

Zebra finch song behavior is sexually dimorphic: males sing and females do not. The neural system underlying this behavior is sexually dimorphic, and this sex difference is easy to quantify. During development, the zebra finch song system can be altered by steroid hormones, specifically estradiol, which actually masculinizes it. Because of the ease of quantification and experimental manipulation, the zebra finch song system has great potential for use in undergraduate labs. Unfortunately, the underlying costs prohibit use of this system in undergraduate labs. Further, the time required to perform a developmental study renders such undertakings unrealistic within a single academic term. We have overcome these barriers by creating digital tools, including an image library of song nuclei from zebra finch brains. Students using this library replicate and extend a published experiment examining the dose of estradiol required to masculinize the female zebra finch brain. We have used this library for several terms, and students not only obtain significant experimental results but also make gains in understanding content, experimental controls, and inferential statistics (analysis of variance and post hoc tests). We have provided free access to these digital tools at the following website: http://mdcune.psych.ucla.edu/modules/birdsong.  相似文献

There has been a disturbing decline in the take-up of physics within second-level education in Ireland since the early nineties. Here, an analysis is presented of the main factors influencing the take-up of physics from the perspective of secondary school teachers. The database underpinning the analysis is based on a comprehensive survey of teacher opinion in Irish schools conducted in December 2004. The sample included all such schools in Ireland and was directed at school principals, senior cycle physics teachers, and junior cycle science teachers. The data reveal that most senior cycle physics teachers in Ireland do not possess a ‘physics-dominated’ primary degree, are dissatisfied with the technical back-up available to them and their students, consider that many of their students lack the basic mathematical skills needed for physics, believe their students are not adequately informed about career opportunities in physics, and feel students are disadvantaged in regard to grade points in the leaving certificate examination compared with most other subjects. These findings echo those of a previous report by the Government Task Force on the Physical Sciences and lend renewed urgency to the necessity of implementing a comprehensive action programme to reverse the decline in physics take-up before it impacts negatively on the Irish economy.  相似文献

There are now over one million foreign students studying in universities or colleges outside their own countries. The number of foreign students increased very rapidly in the 1970s and several host countries became concerned at the rising cost of subsidising students from abroad. Several countries, including Australia and Canada, as well as Britain, introduced differential fees for overseas students while other countries use quotas to regulate or restrict foreign student numbers. Other countries, notably Japan, have tried to increase recruitment of foreign students. This paper compares recent enrolment trends and developments in government policy towards foreign students in ten countries (Australia, Belgium, Canada, France, West Germany, India, Japan, Russia, United Kingdom and United States of America ).  相似文献

This study focuses on corporate engagement when shareholder activists raise concerns about social issues during annual shareholder meetings. Building upon strategic communication, social activism, and management research, the study combines Stakeholder Salience Theory (SST) and Issues Management Theory to explain corporate responses to shareholder activism. The researchers constructed a dataset of 844 shareholder actions in the U.S., all concerning environmental issues from 2006 to 2014. The analyses revealed that the urgency of the shareholder requests was the main driver of saliency. Moreover, shareholder activism strategies that engage corporations in private negotiations appeared to be effective in eliciting positive corporate responses. The findings contribute to applied communication theory and research by advancing SST with an issues management perspective in the context of shareholder activism.  相似文献

Maureen Crago collaborated with Hugh Crago on their longitudinal studyPrelude to Literacy: A Preschool Child's Encounter with Picture and Story. Since then, she has been in private practice as a psychotherapist. She is currently reexamining the rich store of observation on whichPrelude was based for a series of articles that widen and deepen the focus of the original study.  相似文献
