11th Brazilian – German Frontiers of Science and Technology Symposium

Conference, Digitalisation — October 23, 2020
Prof. Drachsler was invited to the 11th Brazilian – German Frontiers of Science and Technology Symposium. The focus of the event was on challenging times and progress of science & engineering with the current circumstances imposed by the COVID-19 pandemic. These times require creative approaches and stimulating individuals working on new solutions for the challenges of our time, realizing new solutions. In this view the BRAGFOST symposium aims to bring together young but experienced scientists and create the environment fostering a vibrant exchange with interesting colleagues from their own field and furthermore transdisciplinary exchange. The generalizable basis of complexity in our world already transcendent from science and natural systems more and more into our every days life – social systems, finances, economy up to education. Finding new solutions currently involves…

Learning Analytics Cookbook – How to Support Learning Processes Through Data Analytics and Visualization

Learning Analytics Cookbook – How to Support Learning Processes Through Data Analytics and Visualization

Publication — August 1, 2020
This book offers an introduction and hands-on examples that demonstrate how Learning Analytics (LA) can be used to enhance digital learning, teaching and training at various levels. While the majority of existing literature on the subject focuses on its application at large corporations, this book develops and showcases approaches that bring LA closer to smaller organizations, and to educational institutions that lack sufficient resources to implement a full-fledged LA infrastructure. In closing, the book introduces a set of software tools for data analytics and visualization, and explains how they can be employed in several LA scenarios.

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

open access, Publication, Study — July 11, 2020
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, open access, Study — July 8, 2020
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…

Das studentische E-Learning-Projekt »StudyCore« verbindet Forschung mit pädagogischer Praxis

Award, Digitalisation — June 25, 2020
Es ist toll zu sehen, dass die Studierendenvereinigung - MEGA - (Make eLearning Great Again) - jetzt auch ausserhalb der Goethe Uni erfolgreich das Lernen mit Technologie verbessert!. Am Anfang vieler guter Ideen steht Frust. „90 Minuten Mathevorlesung, 90 Minuten nur Zahlen und Formeln – so lange konnte ich mich einfach nicht konzentrieren“, gibt Onur Karademir seine Erfahrung im ersten Studiensemester Informatik wieder. Also suchte er im Netz nach Vorlesungs-Videos zum Thema, die er immerhin stoppen, zurück- und vorspulen konnte. Häppchenweise ging Verstehen leichter. Diese Erfahrung war der Impuls, noch als Student E-Learning-Formate zu entwickeln, die vom studiumdigitale- Team der Goethe-Universität gefördert wurden. Inzwischen gibt es das EdTech-Start-up StudyCore, in dem Onur Karademir mit sechs weiteren Studierenden ein breites Angebot an Digitalen Lehr- und Lernformen entwickelt und das eine Perspektive…

Learning analytics in European higher education–trends and barriers

Learning analytics in European higher education–trends and barriers

Publication, Study — May 21, 2020
Learning analytics (LA) as a research field has grown rapidly over the last decade. However, adoption of LA is mostly found to be small in scale and isolated at the instructor level. This paper presents an exploratory study on institutional approaches to LA in European higher education and discusses prominent challenges that impede LA from reaching its potential. Based on a series of consultations with senior managers from 83 different higher education institutions in 24 European countries, we observe that LA is primarily perceived as a tool to enhance teaching and institutional management. As a result, teaching and support staff are found to be the main users of LA and the target audience of training support. In contrast, there is little evidence of active engagement with students or using LA…

Towards Computational Psychometrics by Combining Psychometrics with Learning Analytics

Towards Computational Psychometrics by Combining Psychometrics with Learning Analytics

Publication — May 12, 2020
From a psychometric point of view, assessment means to infer what a learner knows and can do in the real world from limited evidence observed in a standardized testing situation. From a learning analytics perspective assessment means to observe real behavior in digital learning environments to conclude the learner status with the intent to positively influence the learning process. Although psychometrics and learning analytics share similar goals, for instance, formative assessment, while applying different methods and theories, the two disciplines are so far highly separated. This chapter aims at paving the way for an advanced understanding of assessment by comparing and integrating the learning analytics and the psychometric approach of assessment. We will discuss means to show this new way of assessment of educational concepts such as (meta-) cognition, motivation,…

Tracking Patterns in Self-Regulated Learning Using Students’ Self-Reports and Online Trace Data

Tracking Patterns in Self-Regulated Learning Using Students’ Self-Reports and Online Trace Data

open access, Publication, Study — April 15, 2020
For decades, self-report instruments – which rely heavily on students’ perceptions and beliefs – have been the dominant way of measuring motivation and strategy use. Event-based measures based on online trace data arguably has the potential to remove analytical restrictions of self-report measures. The purpose of this study is therefore to triangulate constructs suggested in theory and measured using self-reported data with revealed online traces of learning behaviour. The results show that online trace data of learning behaviour are complementary to self-reports, as they explained a unique proportion of variance in student academic performance. The results also reveal that self-reports explain more variance in online learning behaviour of prior weeks than variance in learning behaviour in succeeding weeks. Student motivation is, however, to a lesser extent captured with online trace…
