[publication] Technologiegestützte Lehre an der TU Graz in der COVID-19-Pandemie #tugraz #research

Wir haben für das Buch „Wie Corona die Hochschullehre verändert: Erfahrungen und Gedanken aus der Krise zum zukünftigen Einsatz von eLearning“ einen kurzen Beitrag zu „Technologiegestützte Lehre an der TU Graz in der COVID-19-Pandemie“ erstellt und dabei exemplarisch die Umstellung einer Lehrveranstaltung unter Einsatz eines ReDesign-Canvas beschrieben.

Zusammenfassung:
Didaktische Fragestellungen waren bei der Umstellung der Lehre in der COVID-19-Krise auch an der TU Graz zunächst zweitrangig, als es im März 2020 darum ging, vom Präsenzunterricht in den Online-Modus zu wechseln. Im Beitrag wird die Arbeit des Teams „Lehr- und Lerntechnologien“ der TU Graz vor und während der ersten Wochen der COVID-19-Krise vorgestellt. Zu den Angeboten zur Förderung innovativer Lern- und Lehrsettings gehört auch der „ReDesign-Canvas“. Im Beitrag wird beschrieben, wie er beim didaktischen Re-Design in einem konkreten Fallbeispiel eingesetzt wurde. Der Beitrag schließt mit einem Ausblick über die geänderten Voraussetzungen und Strategien für die technologiegestützte Lehre in den kommenden Monaten.

[publication] Property-Based Testing for Parameter Learning of Probabilistic Graphical Models #machinelearning #learninganalytics

Thanks to my colleagues – we did a publication for this year CDMAKE-conference about „Property-Based Testing for Parameter Learning of Probabilistic Graphical Models„.

Abstract:
Code quality is a requirement for successful and sustainable software development. The emergence of Artificial Intelligence and data driven Machine Learning in current applications makes customized solutions for both data as well as code quality a requirement. The diversity and the stochastic nature of Machine Learning algorithms require different test methods, each of which is suitable for a particular method. Conventional unit tests in test-automation environments provide the common, well-studied approach to tackle code quality issues, but Machine Learning applications pose new challenges and have different requirements, mostly as far the numerical computations are concerned. In this research work, a concrete use of property-based testing for quality assurance in the parameter learning algorithm of a probabilistic graphical model is described. The necessity and effectiveness of this method in comparison to unit tests is analyzed with concrete code examples for enhanced retraceability and interpretability, thus highly relevant for what is called explainable AI.

[publication] Learning Analytics and Spelling Acquisition in German – The Path to Individualization in Learning #hcii20 #iderblog

We did a contribution titled „Learning Analytics and Spelling Acquisition in German – The Path to Individualization in Learning“ for this year HCII conference.

Abstract:
This paper shows how Learning Analytic Methods are combined with German orthography in the IDeRBlog-project (www.iderblog.eu). After a short introduction to the core of the platform – the intelligent dictionary – we focus on the presentation and evaluation of a new training format. The aim of this format is, that pupils can train misspelled words individually in a motivating and didactic meaningful setting. As a usability test was run with twenty one third graders, we are able to present the results of this evaluation.

[publication] Open educational resources in continuing adult education: development in the German-speaking area #OER #research

Our article about „Open educational resources in continuing adult education: development in the German-speaking area“ got published in the Journal „Smart Learnining Environment„. We aimed to give a short overview about the situation in the german-speaking area.

Abstract:
Open Educational Resources (OER) allow many different uses in educational work that are excluded from traditional materials by copyright laws, such as modifying and republishing existing materials. This article examines the current role of OER in the field of adult education in German-speaking area, especially in Germany, Austria and Switzerland. Although nowadays the topic of digitization is given a high strategic importance in continuing education in Switzerland, OER plays just a subordinate role there.

[publication] Learning Analytics Challenges to Overcome in Higher Education Institutions #LearningAnalytics #tugraz #research

Our chapter on „Learning Analytics Challenges to Overcome in Higher Education Institutions“ got published in the book „Utilizing Learning Analytics to Support Study Success

Abstract:

While a large number of scientific publications explain the development of prototypes or the implementation of case studies in detail, descriptions of the challenges and proper solutions when implementing learning analytics initiatives are rare. In this chapter, we provide a practical tool that can be used to identify risks and challenges that arise when implementing learning analytics (LA) initiatives and discuss how to approach these to find acceptable solutions. In this way, implementers are given the opportunity to handle challenges early on and avoid being surprised at a critical moment in the project, which will save time, resources, and effort. We are aware that all aspects needed to successfully carry out learning analytics initiatives are co-dependent. Nonetheless, we identified and categorized the criteria necessary for implementing successful learning analytics initiatives. We conclude this chapter with an overview of the challenges faced and possible approaches that can be taken to facilitate the successful implementation of learning analytics.

[publication] Can Learning Analytics Find Success in Didactical Measurements? Results from a MOOC Case Study #tugraz #research

We are very proud to be part of the book „Digital Workplace Learning“ with a contribution about our MOOC research. This time we take a look to a particular MOOC and reported about the case study. Our chapter „Can Learning Analytics Find Success in Didactical Measurements? Results from a MOOC Case Study“ is now published.

Abstract:

In recent years, massive open online courses (MOOCs) led the road into a new era of learning environment systems. Since 2008, e-Learning witnessed a new type of course which is massive in student numbers, open for anyone, and available for all without limitations. MOOCs integrate social networking, accessible online resources, and open-ended outcomes and are publicly shared. In addition, MOOCs offer several online variables that allow researchers from analytical disciplines (learning analytics) to translate these variable data values into research actions and interpret patterns. In this chapter, we present a detailed analysis of a MOOC case study offered in the previous 2 years, 2015 and 2016. The Graz University of Technology, the University of Graz, and partners from the Medical University of Graz collaborated on a project producing a MOOC called “Dr. Internet.” This MOOC aims to investigate whether the Internet helps or hurts in the endeavor to increase health literacy of the public and how it affects the practitioner-patient relationship. Nevertheless, the research study in this chapter is looking onto a different point of view. We will follow a quantitative investigation and apply learning analytics techniques on learners’ behavior as well as scrutinize traces they left behind in videos, discussion forums, and quizzes. In addition, we try to further inspect the dropout rate and level of engagement. It can be outlined that the early analysis results show that those MOOCs behaved similar to other studies but they differ in the higher number of reads in the discussion forum. Reasonable didactical interventions assisted to change learners’ attitudes toward online learning. This chapter will also describe the didactical approach of the Dr. Internet MOOCs.

[publication] Tutoring writing spelling skills within a web-based platform for children #iderblog #LearningAnalytics

Our publication about „Tutoring writing spelling skills within a web-based platform for children“ got published. We are describing our research project IDERblog and the results using learning analytics.

Abstract:

According to the NMC Horizon Report (Johnson et al. in Horizon Report Europe: 2014 Schools Edition, Publications Office of the European Union, The New Media Consortium, Luxembourg, Austin, 2014 [1]), data-driven learning in combination with emerging academic areas such as learning analytics has the potential to tailor students’ education to their needs (Johnson et al. 2014 [1]). Focusing on this aim, this article presents a web-based (training) platform for German-speaking users aged 8–12.Our objective is to support primary-school pupils—especially those who struggle with the acquisition of the German orthography—with an innovative tool to improve their writing and spelling competencies. On this platform, which is free of charge, they can write and publish texts supported by a special feature, called the intelligent dictionary. It gives automatic feedback for correcting mistakes that occurred in the course of fulfilling a meaningful writing task. Consequently, pupils can focus on writing texts and are able to correct texts on their own before publishing them. Additionally, they gain deeper insights in German orthography. Exercises will be recommended for further training based on the spelling mistakes that occurred. This article covers the background to German orthography and its teaching and learning as well as details concerning the requirements for the platform and the user interface design. Further, combined with learning analytics we expect to gain deeper insight into the process of spelling acquisition which will support optimizing our exercises and providing better materials in the long run.
