[workshop] Learning Analytics für den Mathematikunterricht der Primarstufe

Unsere Abteilungen beschäftigt sich nun schon seit einigen Jahren ganz stark mit Learning Analytics in der Primarstufe – angefangen hat es mit dem Einmaleinstrainer, heute haben wir auch einen mehrstelligen Multiplikationstrainer, Plus- und Minustrainer bzw. steht der Divisionstrainer kurz vor dem Start.
Alles findet man unter http://schule.learninglab.tugraz.at und kann frei von allen Schulen genutzt werden. Wir haben dies im Rahmen eines Workshops an der Fachdidaktik Informatik Tagung vorgestellt und dabei dieses Handout verteilt:

[publication] Towards a Learning-Aware Application Guided by Hierarchical Classification of Learner Profiles #jucs

Our publication about “Towards a Learning-Aware Application Guided by Hierarchical Classification of Learner Profiles” is published as part of the Special Issue on Learning Analytics.

Abstract:

Learner profiling is a methodology that draws a parallel from user profiling. Implicit feedback is often used in recommender systems to create and adapt user profiles. In this work the implicit feedback is based on the learner’s answering behaviour in the Android application UnlockYourBrain, which poses different basic mathematical questions to the learners. We introduce an analytical approach to model the learners’ profile according to the learner’s answering behaviour. Furthermore, similar learner’s profiles are grouped together to construct a learning behaviour cluster. The choice of hierarchical clustering as a means of classification of learners’ profiles derives from the observations of learners behaviour. This in turn reflects the similarities and subtle differences of learner behaviour, which are further analysed in more detail. Building awareness about the learner’s behaviour is the first and necessary step for future learning-aware applications.

[imoox] Start “Gesellschaftliche Aspekte der Informationstechnologie” #imoox #gadi15

Meine Lehrveranstaltung “Gesellschafliche Aspekte der Informationstechnologie” die heuer erstmal als Massive Open Online Course (MOOC) durchgeführt hat, startet heute auf der Plattform iMooX. Neben meiner Einführung kommen diese Woche zwei weitere Experten zu Wort – Günter Schreier und Andreas Holzinger – und widmen sich dabei dem Problemfeld eHealth und Big Data in der Medizin.

Special Issue: Learning Analytics #jucs

Our Special Issue about Learning Analytics is published within the Journal of Universal Computer Science. We like to thank all authors and reviewers for their valuable work. All readers we wish an enjoyable reading experience.

Already back in 2006 Retalis et al. proposed their first thoughts on Learning Analytics (LA) and considered interaction analysis as a promising way to better understand the learner’s behavior. A couple of years later, further activities were organized; especially Siemens and Long predicted that the most important factor shaping the future of higher education would be big data and analytics. Just few months later, the Horizon Report also described Learning Analytics as a big trend for the forthcoming years. Since then a number of conferences (for example LAK 11, LAK 12, …) have been organized and different projects have been started as well as the topic has been rising on Google trends. The number of research publications has also increased arbitrarily in different directions; for instance to define the upcoming research field, to gather practical experiences or simply to confine LA from other topics (especially from Educational Data Mining (EDM)) …

[presentation] Lehramsstudium Informatik

Im Rahmen der Fachdidaktik Informatik Tagung an der Pädagogischen Hochschule Steiermark veranstaltet vom regionalen Fachdidaktikzentrum Informatik (RFDZI) habe ich heute den derzeitigen Stand zur PädagogInnen Ausbildung im Entwicklungsverbund aus dem Fachbereich Informatik präsentiert. Hier die wenigen Folien:

[seminar, presentation] Technology Enhanced Learning

Schon wieder ein Jahr vorbei und ich darf wieder mein Seminar “Technology Enhanced Learning” starten. Vorgesehen ist das Seminar vor allem für Lehramtsstudierende Informatik, aber natürlich sind alle anderen Studierenden herzlich willkommen. In der ersten Einheiten versuche ich einen Schnelleinstieg ins Thema kombiniert mit einer Zukunftssicht, wohin sich der Medieneinsatz entwickeln könnte.
Hier sind die Folien:

[publication] Using Cloud Services in a Modern Learning Management System

Our publication “Using Cloud Services in a Modern Learning Management System” as part of a Special Issue of the Journal of Computing and Information Technology (CIT) has been published online.
Abstract:

LMS (Learning Management Systems) today are being widely used in almost every educational facility. In the last years all conceivable use cases that need to be carried out by such LMS have been defined and the features a modern LMS needs to offer are very clear. Rarely do we find something a teacher or student needs that an LMS cannot offer. So the task for LMS developers shifted from offering all tools a teacher or student needs to make these tools as convenient to use as possible. Our goal in this research work is to describe the web services we use in TeachCenter, an LMS that has been widely used for the past years at Graz University of Technology to simplify the use of certain components. It can be pointed out that cloud services have to be an integral part of a modern LMS.

[publication] Leveraging Learning Analytics in a Personal Learning Environment using Linked Data

Our publication about “Leveraging Learning Analytics in a Personal Learning Environment using Linked Data” for the Bulletin of the Technical Committee on Learning Technology is now online available.
Abstract:

We report on the reflection of learning activities and revealing hidden information based on tracking user behaviors with Linked Data. With in this work we introduce a case study on usage of semantic context modelling and creation of Linked Data from logs in educational systems like a Personal Learning Environment (PLE) with focus on reflection and prediction of trends in such systems. The case study demonstrates the application of semantic modelling of the activity context, from data collected for over two years from our own developed widget based PLE at Graz University of Technology. We model learning activities using adequate domain ontologies, and query them using semantic technologies as input for visualization which serves as reflection and prediction medium as well for potential technical and functional improvements like widget recommendations. As it will be shown, this approach offers easy interfacing and extensibility on technological level and fast insight on trends in e-learning systems like PLE.

Meine Mission: Bildungsinhalte öffentlich zugänglich und nutzbar zu machen

OER - Martin Ebner… so zitiert mich das neue MediaMagazin des Mediamarktes in der Ausgabe 01/2015. Auch haben Sie das Interview abgedruckt, welches bereits Ende letzten Jahres im Saturn Magazin war. Ich hoffe, dass dadurch weitere Bevölkerungsteile auf uns bzw. iMooX aufmerksam werden und sich daran beteiligen.

Hier geht es zur [Online Version] des Magazin und hier zur [.pdf Version]
