What makes a cMOOC community endure? Multiple participant perspectives from diverse cMOOCs

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.

Why Throw the Negs Out with the Bathwater? A Study of Students' Attitudes to Digital and Film Photographic Media

As today's digital applications hold our gaze and become increasingly ubiquitous, it is easy to dismiss the previous technologies and processes that provided yesterday's creative opportunities. Photography has been revolutionised by digital capture and transmission in the past decade. It could be argued that there is a digital orthodoxy in education, which has democratized and engaged increasing numbers of students, and has had a particular influence in A Level Photography. Over the past decade many traditional darkrooms have been replaced by computer suites. My concern is that if secondary schools and colleges with the facilities to teach film are forced to convert to a singular digital mode, we may be throwing the negs out with the bathwater. This study uses qualitative and quantitative research that I have undertaken at a Further Education college in England. It explores students' attitudes to learning Photography with an artistic curiosity, which includes experiential learners, and those that eschew the digital age who are content with the organic variety of analogue learning that film offers. They make their own case for maintaining the opportunity to learn through hybrid activity that embraces both media, for a multiplicity of learning opportunities and media that are not limited by any orthodoxy, digital or otherwise.     

建构主义语境下《英美概况》数字化教学模式研究

信息化时代中《英美概况》课程教学应该以培养学生思辨能力和跨文化交际能力为核心,充分利用数字新媒体,从师生教学主体入手,共同建构内在的文化知识体系,在对西方文化现象了解和理解的基础上进行反思与借鉴。本文依据主体认知建构论和社会、文化建构思想,结合教学主体、内容、过程和手段,探讨《英美概况》课程的数字化教学模式,从而充分利用信息化平台所营造的互动交流空间,调动认知主体的能动性、思辨性和创造性,更有利于培养学生处理文化差异的敏感性、宽容性、灵活性和跨文化交流能力。
