MOOC Video Interaction Patterns: What Do They Tell Us?

Pierre Dillenbourg, Patrick Jermann, Lukasz Kidzinski, Nan Li

For MOOC learners, lecture video viewing is the central learning activity. This paper reports a large-scale analysis of in-video interactions. We categorize the video behaviors into patterns by employ- ing a clustering methodology, based on the available t ...

MOOCs are More Social than You Believe

Pierre Dillenbourg, Nan Li, Himanshu Verma, Afroditi Skevi

We report about two ongoing studies, which challenge the individualistic model of MOOC based learning. MOOC usage is embedded in the context of collocated study groups. The ability to pause a lecture and discuss its contents with peers creates learning opp ...

Active Learning of Multi-Index Function Models

Volkan Cevher, Hemant Tyagi

We consider the problem of actively learning \textit{multi-index} functions of the form

f(x) = g(Ax)= \sum_{i=1}^k g_i(a_i^Tx)

from point evaluations of

f

. We assume that the function

f

is defined on an

\ell_2

-ball in

\Real^d

,

g

is twice contin ...

Effectiveness of a Clinically Integrated e-Learning Course in Evidence-Based Medicine for Reproductive Health Training A Randomized Trial

Shawn Koppenhoefer

Context For evidence-based practice to embed culturally in the workplace, teaching of evidence-based medicine(EBM) should be clinically integrated. In low-middle-in come countries (LMICs) there is a scarcity of EBM-trained clinical tutors, lack of protecte ...

On the generalization ability of distributed online learners

Ali H. Sayed

We propose a fully-distributed stochastic-gradient strategy based on diffusion adaptation techniques. We show that, for strongly convex risk functions, the excess-risk at every node decays at the rate of O(1/Ni), where N is the number of learners and i is ...

Trade Liberalization, Firm Heterogeneity, and Labor Layoffs: An Empirical Investigation

Pinar Uysal

This is the first empirical attempt to provide evidence for the interaction between firm-level total factor productivity and trade liberalization as key determinants of firm-level job destruction caused by trade. Employing an original US firm-level data, w ...
