New pub: key technical features of automated feedback systems - a systematic feature analysis

New publication alert from the HyTea project titled "Enhancing presentation skills: key technical features of automated feedback systems - a systematic feature analysis", led by PhD candidate Stefan Hummel

The article presents a systematic analysis of oral presentation automated feedback systems (OPAFs), which are designed to support public speaking through automated feedback mechanisms.

Our study assessed 14 existing systems across a comprehensive set of 83 functional features and 12 additional aspects. Although there is an increased interest in these systems, we found that the overall implementation rate of key features remains low at just 16%, with notable gaps in critical areas like verbal-nonverbal congruency, adaptive feedback, and content structuring.

Moreover, evaluation methodologies tend to focus heavily on usability and user experience, while aspects such as learning outcomes and pedagogical value are often overlooked. The majority of studies are lab-based, which raises concerns about the generalisability of findings to real-world educational environments.

Our findings emphasise the importance of improved feature integration, real-world testing, and closer collaboration with educators to help transition these tools from experimental prototypes to effective educational technologies.

This is the first journal article published about the HyTea project and contributed substantially to building a solid foundation for Presentable (www.presentable.info).

This milestone was especially significant as it marks my first article published as the last author. Well done, Stefan, thanks to my co-authors and everyone who supported this research.

Pitch session: Learning with Machines

On the 14th December 2017, during the (y)OUr day organised by the Open Universiteit I was invited to prepare a pitch of 3 minutes about my research. Here is what I said.

My name is Daniele Di Mitri and I am PhD candidate at the TELI department of the Welten institute. My field of research is learning analytics. The Open Universiteit is a distance university that provides its education online. With Learning Analytics it is possible to collect the user-interaction events, analyse these data and provide more personalisation opportunities to the students.
