[publication] Insights into Learning Competence Through Probabilistic Graphical Models #tugraz #research

We contributed to this year „Third IFIP TC 5, TC 12, WG 8.4, WG 8.9, WG 12.9 International Cross-Domain Conference (CD-MAKE 2019)“ with a publication titled „Insights into Learning Competence Through Probabilistic Graphical Models„.

Abstract:

One-digit multiplication problems is one of the major fields in learning mathematics at the level of primary school that has been studied over and over. However, the majority of related work is focusing on descriptive statistics on data from multiple surveys. The goal of our research is to gain insights into multiplication misconceptions by applying machine learning techniques. To reach this goal, we trained a probabilistic graphical model of the students’ misconceptions from data of an application for learning multiplication. The use of this model facilitates the exploration of insights into human learning competence and the personalization of tutoring according to individual learner’s knowledge states. The detection of all relevant causal factors of the erroneous students answers as well as their corresponding relative weight is a valuable insight for teachers. Furthermore, the similarity between different multiplication problems – according to the students behavior – is quantified and used for their grouping into clusters. Overall, the proposed model facilitates real-time learning insights that lead to more informed decisions.

[conference proceeding] EMOOCs 2016 #graz #emoocs2016

Timley, just one week for conference start the „Proceedings of the European Stakeholder Summit on experiences and best practices in and around MOOCs (EMOOCS 2016)“ are online. Enjoy a huge number of research publications and experience reports as well as some posters in the end. Of course we will love if you visit us in Graz to great discussions on MOOCs.

[publication] What do we know about typical MOOC participants? First insights from the field

Our publication about „What do we know about typical MOOC participants? First insights from the field“ at this year eMOOCs 2015 conference, Mons (Belgium) is now online available.
Abstract:

Massive Open Online Courses became a worldwide phenomenon. Especially in Central Europe it is a subject of debates whether universities should invest more money or not. This research study likes to give first answers about typical MOOC participants based on data from different field studies of the Austrian MOOC-platform iMooX.
It can be pointed out that the typical learner is a student or an adult learner, strongly interested in the course topic or just interested in learning with media and finally with self- contained learning competencies. The research work concludes that MOOCs broaden the educational field for universities and are a possibility to educate the public in a long run.
