Student performance prediction in SlideWiki at 8th Conference on e-Learning, Belgrade

In September we had the opportunity to present as part of this year’s eLearning Conference (http://econference.metropolitan.ac.rs/), held from September 28-29, 2017 at Belgrade, Metropolitan University.

Our presentation was based on the research paper entitled “Educational data mining for student performance prediction in SlideWiki OpenCourseWare platform” by Dr Nikola Tomasevic, Dejan Paunovic and Prof. Dr Sanja Vranes from The “Mihajlo Pupin” Institute. During the session, we introduced the SlideWiki project to the international audience and presented preliminary results and conceptual approaches to student performance prediction in SlideWiki. The approaches included a number of machine learning techniques (k-NN, SVM, ANN, decision trees, naïve Bayes, matrix factorization, etc.) which were compared using the Open University Learning Analytics Dataset (OULAD). The techniques were also evaluated using both classification and regression tasks for predicting the student performance. In addition we showed how different combinations of input data (in terms of student demographic, engagement and performance data) were investigated in order to discover the optimal input dataset for predictions. Finally, we discussed some important challenging points that had been identified with implementing the SlideWiki learning analytics module.

The Eighth International Conference on eLearning 2017 was organized by the Belgrade Metropolitan University, the Open University of the Netherlands as well as the Mathematical Institute of the Serbian Academy of Science. The conference started with some welcoming words and a presentation about the importance of the eLearning Conference from the Headmaster of the Metropolitan University, Professor Dragan Domazet. The conference brought together experts in field of eLearning from various countries. They shared their experience, presented new developments in this field, and also discussed about innovative methods.

This years eLearning Conference was focused on:

  • Technical concepts of eLearning,
  • Instructional design of eLearning, and
  • Pedagogical/psychological aspects of eLearning.

The main topics discussed during the conference were design and development of online courses, use of learning objects, learning analytics, personalized learning, gamification of learning, massive open online courses, while the Keynote presentation was dedicated to “Open educational resources”.
