Massive Open Online Courses (MOOCs) have gained a lot of attention in the last years as a new technologyenhanced learning (TEL) approach in higher education. MOOCs provide more educational opportunities to a massive number of learners to attend free online courses around the globe. Discussions around MOOCs have been focusing on the potential, social,(More)
The personal learning environment (PLE) concept offers a learner-centric view of learning and suggests a shift from knowledge-push to knowledge-pull approach to learning. One concern with a PLE-driven knowledge-pull approach to learning, however, is information overload. Recommender systems can provide an effective mechanism to deal with the information(More)
In this paper we describe an experiment, in which we examined older and younger adults when interacting with a simulated PDA (personal digital assistant). Independent variables were users' age (young vs. older) and device interface (hyperlink vs. no hyperlink). Dependent variables were the effectiveness and efficiency of menu navigation. To understand how(More)
Learning analytics tools should be useful, i.e., they should be usable and provide the functionality for reaching the goals attributed to learning analytics. This paper seeks to unite learning analytics and action research. Based on this, we investigate how the multitude of questions that arise during technology-enhanced teaching and learning systematically(More)

MOOCs have unique features that make it an effective technology-enhanced learning (TEL) model in higher(More)
Video-Based Learning (VBL) has a long history in the educational design research. In the past decade, the interest in VBL has increased as a result of new forms of online education, such as flipped classrooms, and most prominently MOOCs. VBL has unique features that make it an effective Technology-Enhanced Learning (TEL) approach. This study critically(More)
Lack of proper English pronunciations is a major problem for immigrant population in developed countries like U.S. This poses various problems, including a barrier to entry into mainstream society. This paper presents a research study that explores the use of speech technologies merged with activity-based and arcade-based games to do pronunciation feedback(More)
