Cui bono? On the relative merits of technology-enhanced learning and teaching in higher education

This article provides evidence from a 4-year longitudinal study on the comparative use of illustrative video podcasts during Economic Geography lectures vis-à-vis traditional educational methods in order to guide pedagogic practice and future research on the relative merits of technology-enhanced learning in higher education. Key benefits derived from the introduction of video podcasts identified in this study included positive affective and cognitive attitudes of students towards educational technologies, increased teacher satisfaction and improved teaching evaluations. Key challenges included negative impact of video podcasts on student behaviour (attendance and broader engagement), and uncertain impact on learning performance (exam scores). The study highlights the benefit of sequencing the improvements to the learning/teaching process, starting with a module review and revised content, before proceeding towards the integration of learning technologies into the content delivery. More broadly, the paper calls for pedagogy to remain vigilant, critically reflecting on the intricate relationship between educational technologies, teaching content, and the wider socio-political context.     

库库提尼文明——新石器时代彩陶研究资料库的建立

库库提尼的新石器时代陶器距今约5000年,它是Ariusd-- CucuteniTripolie古人类活动带的一部分,位于欧洲东南部。对这种三色彩陶器的研究是法国和罗马尼亚的合作项目,基金来源是Brancusi项目提供,研究方向是制陶的黏土成分、烧制温度、用于涂彩的颜料层（白、红、黑）,陶器式样模型材料等。库库提尼文化是19世纪末第一个被发现的,它经历了约120年的流逝,由于过去对它的研究主要为考古调查,处于对它特殊性的好奇,才带出了本课题。本文报道了用岩相学分析的结果,通过对陶质材料进行SEMEDX,XRF检测,得到了库库提尼从A期、AB期到B期的不同进化阶段的岩相学陶层资料,现已发现的Scanteia,TarguFrumos,Ruginoasa,Cucuteni,Isaia,Poienesti考古遗址也符合这种进化阶段。本项目的目的是创建一个基础数据库,使有关库库提尼的资料数据能完整统一地输入古代欧洲研究数据库。
