Making education available to everyone is about opening new doors to the future world where people are living with their full abilities and potentials. This vision was acknowledged by UNESCO and it was one of the main motivations for introducing Open Educational Resources (OER) in 2002. Over the last two decades, OER have made a positive impact on...

This article presents the first iteration of the video analytics system VA4ME that enables the logging of video interactions in Moodle without the need to provide the videos by a separate plugin or website. Instead, the logging plugin injects, if allowed within a course, JavaScript code that logs video interactions and transforms these logs into xA...

Active and personalized learning requires that teachers can remix a wide variety of sources into new learning resources, which in turn may be customized by students. While this is well-supported for paper-oriented resources, multimodal, interactive learning resources for digital use, called explorables, are much more difficult to author and remix....

The teachers’ attention is an important factor in managing a classroom effectively. It affects students’ learning outcomes and is different for novice and experienced teachers.

Existing anti-phishing learning games rely on the same simple game mechanics that do not allow for detailed assessment of the players’ acquired knowledge and skills. They focus mostly on factual and conceptual knowledge to remember or understand. To extend the research field, this paper presents two new games: The first game implements an extended...

The Gamified Learning Theory implies that gamification does not affect learning directly but stimulates a learning-related behavior in a mediating or moderating process. A learner-related behavior can, to some extent, be predicted based on the way learners tend to perceive, understand and utilize information. These different ways of learning are kn...

First steps in programming often take place in a self-regulated learning process, online and without supervision or assistance of a teacher. When problems occur, novices depend on automated feedback from the programming learning environment or sample solutions, which do not necessarily fit the approach of the learners. Our goal is to identify and cl...

Electronic assessments are a topic of growing importance for universities. Even though it is not a new approach, there still is no “common way” for implementing these assessments. Often times, the assessment is conducted in a computer lab of the educating institution. Still, this approach has some drawbacks, for example the costs and management ove...

Various game-based learning applications and learning games have been developed in the past but similar to the teacher’s curse in Harry Potter, they do...

The forethought phase is the first step in self-regulated learning (SRL) in which learners analyze and plan their short- and long-term learning goals. Good strategic planning is crucial for further learning success, but it is also hard to maintain as it relies on one’s personal beliefs, self-efficacy, and especially motivation. Learners’ may skip o...

Game-based learning is a promising approach to anti-phishing education, as it fosters motivation and can help reduce the perceived difficulty of the educational material.
