[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] Individualized Differentiated Spelling with Blogs – Implementing and Individualizing (IDeRBlog ii) #iderblog #hcii2020 #tugraz

We did a contribution titled “Individualized Differentiated Spelling with Blogs – Implementing and Individualizing (IDeRBlog ii)” for this year HCII conference.

Abstract:
The paper depicts the Erasmus+ project “Individual DifferEntiated correct writing with Blogs – Individualizing and Implementing (IDeRBlog ii)”. IDeRBlog ii is a follow-up project evolving the result of IDeRBlog, a blogging platform for pupils aged eight and above. The project is an international cooperation between 3 countries in Europe. This paper presents an overview of possibilities in context of individualization of the exercises. Further, it covers the benefits of using the platform, e.g. learning about media competences, how to communicate online and the possibility to get individualized exercises for supported during their writing process by the feedback of the intelligent dictionary.

[publication] Mobile Learning Applications for Android und iOS for German Language Acquisition based on Learning Analytics Measurements #LearningAnlytics #IdERblog

We did a contribution to the International Journal of Learning Analytics and Artificial Intelligence for Education (iJAI) titled “Mobile Learning Applications for Android und iOS for German Language Acquisition based on Learning Analytics

Abstract:
The use of digital media is increasingly being promoted in school teaching. Since this aspect changes the interaction between teachers and pupils, this research is concerned with the development of a prototype of a mobile application for Android and iOS, in which different learning applications for language acquisition are offered on the basis of learning analytical measurements provided by experts in the field. By logging and collecting interactions of the user, it is possible to create a variety of statistical evaluations and thus respond to the needs and weaknesses of students. For the evaluation of the application, a user experience test was carried out, whereby the child-friendly operation of the application was tested. Due to the very positive feedback, the design was found to be good and can therefore be further developed.

[publication] Learning Analytics: Einsatz an österreichischen Hochschulen #fnma #LearningAnalytics

Unsere gemeinsaem Publikation zu “Learning Analytics: Einsatz an österreichischen Hochschulen” versucht ein gemeinsames Verständnis für das Themenfeld zu schaffen und ist nun auch online zugänglich:

Zusammenfassung:

Learning Analytics ist sowohl international als auch national ein immer mehr an Bedeutung gewinnendes Themenfeld, welches dabei helfen kann, Lehr- und Lernprozesse besser zu verstehen und gezielt zu optimieren. Dieses Whitepaper soll eine erste Orientierung zu diesem Thema geben und dabei speziell die österreichische Hochschullandschaft adressieren.
Ausgehend von der Definition: “Learning Analytics umfasst die Analyse, Darstellung und Interpretation von Daten aus Lehr- und Lernsettings mit dem Zweck, dass Lernende ihr Lernen unmittelbar verändern können” werden Herausforderungen benannt und der Status Quo in Österreich präsentiert. Daraus werden sechs Argumente für Learning Analytics abgeleitet und vier konkrete Handlungsempfehlungen ausgesprochen.
