Publication of the Compendium of Gamification Strategies: AR in STEM classes in the EU

Project, Publication
The only limit is our imagination: Augmented Reality Technology enters STEM classes in EU As a powerful storytelling tool, immersive media fundamentally change the way we interact with our environment. The EU-funded AR4STEAM project wants to use this potential for new ways of learning in school lessons in natural sciences and arts. With Augmented Reality (AR) we can merge digital dimension with the physical world and create completely new experiences. Reality becomes a creative canvas on which we can provide information in a completely new and exciting way. Artists and scientists have long recognized that immersive technologies appeal to recipients emotionally on a whole new level and create lasting impressions. AR makes the previously impossible a new reality. The only limit? Our imagination! Studies have shown that the use of…

From students with love: An empirical study on learner goals, self-regulated learning and sense-making of learning analytics in higher education

From students with love: An empirical study on learner goals, self-regulated learning and sense-making of learning analytics in higher education

Empirical Study, Open access, Publication
Unequal stakeholder engagement is a common pitfall of adoption approaches of learning analytics in higher education leading to lower buy-in and flawed tools that fail to meet the needs of their target groups. With each design decision, we make assumptions on how learners will make sense of the visualisations, but we know very little about how students make sense of dashboard and which aspects influence their sense-making. We investigated how learner goals and self-regulated learning (SRL) skills influence dashboard sense-making following a mixed-methods research methodology: a qualitative pre-study followed-up with an extensive quantitative study with 247 university students. We uncovered three latent variables for sense-making: transparency of design, reference frames and support for action. SRL skills are predictors for how relevant students find these constructs. Learner goals have a significant…

Towards Real-Time Multimodal Feedback with the CPR Tutor

Towards Real-Time Multimodal Feedback with the CPR Tutor

Conference, Empirical Study, Open access
We developed the CPR Tutor, a real-time multimodal feedback system for cardiopulmonary resuscitation (CPR) training. The CPR Tutor detects mistakes using recurrent neural networks for real-time time-series classification. From a multimodal data stream consisting of kinematic and electromyographic data, the CPR Tutor system automatically detects the chest compressions, which are then classified and assessed according to five performance indicators. Based on this assessment, the CPR Tutor provides audio feedback to correct the most critical mistakes and improve the CPR performance. To test the validity of the CPR Tutor, we first collected the data corpus from 10 experts used for model training. Hence, to test the impact of the feedback functionality, we ran a user study involving 10 participants. The CPR Tutor pushes forward the current state of the art of…
