Required Collaborative Work in Online Courses: A Predictive Modeling Approach          下载免费PDF全文

Marlene A. Smith  Deborah L. Kellogg 《Decision Sciences Journal of Innovative Education》2015,13(4):563-581

This article describes a predictive model that assesses whether a student will have greater perceived learning in group assignments or in individual work. The model produces correct classifications 87.5% of the time. The research is notable in that it is the first in the education literature to adopt a predictive modeling methodology using data collected via a designed experiment. All subjects experienced both a collaborative and an individual assignment, thus mitigating uncontrolled external factors in the measurement of differences in perceived learning. The exploratory nature of the work prompted the use of Partial Least Squares Regression for estimation. The work serves as an illustration of how predictive modeling might enlighten those in educational and academic settings.  相似文献   

MPOC:大规模私有在线课程的设计与运营     

郭文革  沈旭东 《现代远程教育研究》2015,(1):22-32,71

从MOOC发展的动态来看,Coursera、中国大学MOOC、清华学堂在线等都在向SPOC转型,试图通过(在线课程)内容授权和在线课堂(Online Classroom)租赁的方式,寻找盈利模式。以SPOC为基础的MPOC(Massive Private Online Course),通过培养合格的网络辅导教师以及同时开设多个"班"的方式,实现大规模私有在线网络教学,很可能代表了MOOC未来的发展方向。MPOC与MOOC/SPOC,从在线课程的内容和教学活动设计来看,可以共享同一个网络课程设计方案,差异主要体现在运营阶段的班额、收费、师资配备等方面。MPOC课程设计要以学习者分析、教学目标分析等为出发点,注重教学内容的表达,设计有效的教学活动,使课程设计方案落实到教学实施的行为层面。北京大学MPOC课程从2006-2014年,不仅在"班"和"课"的层面上,建立了师生、生生之间的持续教学对话,还在教育机构(学院、大学等办学机构)的层面上,形成了虚拟教育组织和虚拟教学团队。这个成功探索,使"虚拟教育组织"和虚拟教学团队的领导和管理,成为网络教育下一步研究的重要课题。  相似文献   

Examining research on the impact of distance and online learning: A second-order meta-analysis study     

《Educational Research Review》2022

Distance learning has evolved over many generations into its newest form of what we commonly label as online learning. In this second-order meta-analysis, we analyze 19 first-order meta-analyses to examine the impact of distance learning and the special case of online learning on students’ cognitive, affective and behavioral outcomes. We examine to what extent distance learning generation level, and instructional setting moderate the influences of distance learning on cognitive, affective and behavioral outcomes. This second-order meta-analyses also analyzes the first-order meta-analyses for methodological quality and robustness. The findings revealed a statistically significant overall average effect size (g = 0.156, p < .001 with a 95% confidence interval of 0.087–0.224) of distance learning impacting cognitive, affective and behavioral outcomes in comparison to face-to-face learning. Meta-analyses on higher education had a statistically significant larger effect size than K-12 education. Limitations, implications, and directions for future research are discussed.  相似文献   

Tutoring in (online) higher education: Experimental evidence     

《Economics of Education Review》2023

Demand for personalized online tutoring in higher education is growing but there is little research on its effectiveness. We conducted an RCT offering remote peer tutoring in micro- and macroeconomics at a German university teaching online due to the Covid-pandemic. Treated students met in small groups, in alternating weeks with and without a more senior student tutor. The treatment improved study behavior and increased contact to other students. Tutored students achieved around 30% more credits and a one grade level better GPA across treated subjects. Our findings suggest that the program reduced outcome inequality. We find no impacts on mental health.  相似文献

学术论文网络首发的困境及其解决路径——基于中国知网学术期刊网络首发出版发布系统的分析     

唐虹  朱银周 《中国科技期刊研究》2022,33(9):1225

【目的】 探讨学术论文网络首发中存在的困境,并提出解决路径,为期刊编辑部提供参考。【方法】 在与传统出版流程对比的基础上,以中国知网学术期刊网络首发出版发布系统为研究对象,从期刊编辑部、作者、网络出版商和期刊管理部门的角度,分析学术论文网络首发过程中存在的困境,并寻找解决困境的方法。【结果】 学术论文网络首发的困境主要体现在:网络出版商、期刊编辑部和作者三者之间的利益之争,网络出版权及其利益的高度垄断制约着期刊的发展;期刊管理政策与网络首发的内在要求之间的不匹配;现代期刊编辑角色转型带来的编辑角色失调;首发论文的校对标准之争;网络首发论文的认证、引用、评价和撤稿问题;网络首发可能导致论文多个版本共存,容易引起阅读障碍;纸刊存在价值的争议。【结论】 要破解网络首发(网络出版)的困境,最终需要平衡网络出版商、编辑部和作者之间的利益;期刊编辑需要转变为全能编辑;建立基于单篇论文网络首发的期刊出版新模式;实行以网络首发或纸刊出版为最终出版模式的单轨制出版;国家改革网络首发模式下的期刊管理办法,重点监管网刊。  相似文献

Teacher e-mail message strategies and students' willingness to communicate online     

Jennifer Waldeck  Patricia Kearney  Timothy Plax 《Journal of Applied Communication Research》2001,29(1):54-70

In light of the prevalent use of e-mail between teachers and students, researchers have highlighted the need to assess its uses and effects. Relying on the research and thinking of teacher immediacy and extra-class communication, we developed a scale that measures those e-mail message strategies that influence students' willingness to communicate online with their teachers. Next, we isolated those reasons that students use e-mail to interact with their teachers: (1) to clarify course material and procedures, (2) as a means of efficient communication, and (3) for personal/social reasons. Finally, we examined student characteristics such as gender and ethnicity, and history of e-mail use that may (or may not) influence their attitudes toward e-mail exchanges with teachers.  相似文献
