Introduction

The Online Education Research program at TU Delft targets the elements of online education that align with Delft research strengths and allow us to support the next generation of online education - not just in Delft (as EdX partner we are at the forefront of the current drive towards MOOCs), but beyond.  With bringing education online and doing so at unprecedented scales, the role of technology in online education and its research is showing a paradigm shift. The nature and volume of learning data, the interaction between students and educators, and the interaction between all stakeholders in education change, and as a consequence the relevant research becomes more data-driven and computational

Research Lines

We as "Lambda-Lab" (part of the Web Information Systems group) contribute to this research effort. Analyzing the large amount of digital traces learners leave within and outside the online learning environment such as EdX offers the possibility to adapt the environment itself, the teaching material and the manner of conveying knowledge to the individual learners' abilities and preferences. Relying on research methodologies developed across diverse fields such as human-centered design, data science, Web engineering, information retrieval and big data processing, we focus on four main research lines:

  • Beyond the MOOC platform: enriching large-scale online learning through external data sources.
  • Within the MOOC platform: enriching large-scale online learning through MOOC environment adaptations.
  • Search as learning: enriching large-scale online learning through search-based adaptations as search is an important compontent of the learning process.
  • Data analytics in the classroom: enriching the students’ and teachers’ experience in the traditional classroom. This research line is not focused on Massive Open Online Learning, but instead the more traditional higher-education classroom.

Researchers Involved

Several researchers of the WIS group contribute to this research line:

  • Claudia Hauff is an Assistant Professor at WIS and the lab leader of Lambda-Lab. She is the daily supervisor of all MSc and PhD projects within this research line. Contact her via c.hauff@tudelft.nl with any questions about Lambda-Lab.
  • Guanliang Chen: the focus of his PhD research is learner analytics beyond the MOOC platform, funded by TU Delft's Extension School.
  • Dan Davis' PhD research is centered around the impact of the online learning environment on learners and learning, funded as part of CEL.
  • Yue Zhao employs data analytics to make sense of MOOC learners' behaviour.
  • Felipe Moraes is financed by NWO (TOP2 grant) and works on collaborative search questions in the setting of MOOCs.
  • Geert-Jan Houben is the head of WIS and provides expertise in user modeling and Web systems.

as well as a number of Master students:

  • Ioana Jivet explored how to increase self-regulation in MOOC learners through the use of an interactive learning tracker. She defended her thesis in September 2016.  Currently, Ioana is working as a PhD student at the Welten-instituut. Her thesis work contributed to a full paper at LAK 2017.
  • Yingying Bao investigated the prevalence of cheating in MOOCs. She defended her thesis in February 2017. Her thesis work contributed to a short paper at EDM 2017.
  • Jochem de Goede designed a workbench to increase the reproducibility of MOOC experiments.
  • Sambit Praharaj collaborated with researchers from Lugano to bring data analytics to the higher-education classroom. His thesis work contributed to a full paper at UMAP 2017.

We also actively collaborate on projects/papers with external researchers:

  • Vassileios Triglianos and Cesare Pautasso, University of Lugano.
  • Tarmo Robal, Tallinn University of Technology.
  • René Kizilcec, Stanford University.
  • Markus Krause, Telefonica.

Overview of our Work

To get a quick overview of the kind of questions we have looked at in the past year(s), take a look at the slides, they capture the essence of our approach and each of our publications in 1-2 slides (check the speaker notes as well for more insights).
