The means to a blend: A practical model for the redesign of face-to-face education to blended learning

Project, Publication

Learning design models provide guidelines and guidance for educators and course designers in the production and delivery of educational products. It is seen as beneficial to base learning designs on general learning theories, but these must be operationalised into concrete learning design solutions. We, therefore, present one such educational design model: the Design Cycle for Education (DC4E). The model has primarily been created to support the shift from traditional face-to-face education to blended learning scenarios. The cycle describes eight steps that can be used iteratively in the (re)design of educational products and provides educators and course designers with a flexible but clearly structured design model that enables them to reinvent traditional course content for blended learning with appropriate learning design tools.

Policy matters: Expert recommendations for learning analytics policy

Conference, Open access, Publication

Interest in learning analytics (LA) has grown rapidly among higher education institutions (HEIs). However, the maturity levels of HEIs in terms of being ‘student data-informed’ are only at early stages. There often are barriers that prevent data from being used systematically and effectively. To assist higher education institutions to become more mature users and custodians of digital data collected from students during their online learning activities, the SHEILA framework, a policy development framework that supports systematic, sustainable and responsible adoption of LA at an institutional level, was recently built. This paper presents a mix-method study using a group concept mapping (GCM) approach that was conducted with LA experts to explore essential features of LA policy in HEI in contribution the development of the framework. The study identified six clusters of…

Dancing salsa with machines– filling the gap of dancing learning solutions

Open access, Publication

Dancing is an activity that positively enhances the mood of people that consists of feeling the music and expressing it in rhythmic movements with the body. Learning how to dance can be challenging because it requires proper coordination and understanding of rhythm and beat. In this paper, we present the first implementation of the Dancing Coach (DC), a generic system designed to support the practice of dancing steps, which in its current state supports the practice of basic salsa dancing steps. However, the DC has been designed to allow the addition of more dance styles. We also present the first user evaluation of the DC, which consists of user tests with 25 participants. Results from the user test show that participants stated they had learned the basic salsa dancing steps,…

Beyond Reality – Extending a Presentation Trainer with an Immersive VR Module

Open access, Publication

Schneider, J., Romano, G., & Drachsler, H. (2019). Beyond Reality—Extending a Presentation Trainer with an Immersive VR Module. Sensors, 19(16), 3457. The development of multimodal sensor-based applications designed to support learners with the improvement of their skills is expensive since most of these applications are tailor-made and built from scratch. In this paper, we show how the Presentation Trainer (PT), a multimodal sensor-based application designed to support the development of public speaking skills, can be modularly extended with a Virtual Reality real-time feedback module (VR module), which makes usage of the PT more immersive and comprehensive. The described study consists of a formative evaluation and has two main objectives. Firstly, a technical objective is concerned with the feasibility of extending the PT with an immersive VR Module. Secondly, a user experience objective focuses…

Detecting Mistakes in CPR Training with Multimodal Data and Neural Networks

Open access, Publication

This study investigated to what extent multimodal data can be used to detect mistakes during Cardiopulmonary Resuscitation (CPR) training. We complemented the Laerdal QCPR ResusciAnne manikin with the Multimodal Tutor for CPR, a multi-sensor system consisting of a Microsoft Kinect for tracking body position and a Myo armband for collecting electromyogram information. We collected multimodal data from 11 medical students, each of them performing two sessions of two-minute chest compressions (CCs). We gathered in total 5254 CCs that were all labelled according to five performance indicators, corresponding to common CPR training mistakes. Three out of five indicators, CC rate, CC depth and CC release, were assessed automatically by the ReusciAnne manikin. The remaining two, related to arms and body position, were annotated manually by the research team. We trained five…

Profiling sympathetic arousal in a physics course: How active are students?

Publication

Pijeira-Díaz, H.J., Drachsler, H., Kirschner, P.A. & Järvelä, S. (2018). Profiling sympathetic arousal in a physics course: How active are students? Journal of Computer Assisted Learning Abstract Low arousal states (especially boredom) have been shown to be more deleterious to learning than high arousal states, though the latter have received much more attention (e.g., test anxiety, confusion, and frustration). Aiming at profiling arousal in the classroom (how active students are) and examining how activation levels relate to achievement, we studied sympathetic arousal during two runs of an elective advanced physics course in a real classroom setting, including the course exam. Participants were high school students (N = 24) who were randomly selected from the course population. Arousal was indexed from electrodermal activity, measured unobtrusively via the Empatica E4 wristband. Low arousal was the level…
