Required Collaborative Work in Online Courses: A Predictive Modeling Approach

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.     

MPOC:大规模私有在线课程的设计与运营

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。     

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

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.     

Tutoring in (online) higher education: Experimental evidence

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.     

中文维基百科编辑参与率低的原因分析及对策研究

Exploratory Round Table Conferences： in Search of Emerging New Sciences

<正>Science,the never-ending frontier,is a major driving force for innovation in society.Unexpected discoveries in a particular area point to novel streams of innovation in other fields;new insights gained by theory shine light onto many so far untouched challenges.New methods and technologies in research trigger innovations in fields that were believed to be disparate for long.At the same time society expects science to solve important problems in the further development by health care and medicine,pave the road to sustainable technologies and industries that will increase the public wealth and thereby contribute to the well-being of the whole so-     

“研讨式”教学在专业特色课程中的应用探讨--以“环境与资源经济学”为例

环境与资源经济学是一门涉及环境、资源与经济,需要接触大量经济模型并结合许多现实环境问题进行分析的专业特色课程,运用传统的教学模式对该门课程进行讲授无法取得良好的教学效果。而研讨式教学模式则能把课堂氛围变得更为生动吸引人,可集知识性、趣味性、探索性为一体。因此本文就针对这种教学模式在专业特色课程中的应用展开可行性探析。
