New Pub: From Nervous to Noteworthy: Evaluating SPEAKS

Competence development, Conference, Conference, Higher Education

Public speaking can be nerve-wracking, but it’s also a skill every professional needs. Many students leave higher education feeling unprepared to speak confidently in front of an audience. Traditional courses exist, but providing enough guidance to every student is time- and resource-intensive. This is where SPEAKS comes in. SPEAKS (Speech content Preparation for Effective and Authentic Knowledge Sharing) is an educational software designed to guide students through preparing the content of their speeches. The tool and its evaluation were presented at ECEL 2025 in a paper authored by Nina Mouhammad, Jan Schneider, Roland Klemke and Daniele Di Mitri as part of the HyTea-project, highlighting its potential to support students in developing better speech content and becoming more confident regarding public speaking. The tool uses a fully scripted, chat-based interface with…

New Pub: Optimizing Formative Assessment with Learning Analytics

Assessment, Learning Analytics, Literature review, New Pub

The teaching and learning processes in education need to be effective. This is something that all parents, teachers and educational scientists can agree on. To help us track the learners’ achievements and educational progress and ultimately show whether the teaching and learning processes are effective, we rely on formative assessment. Learning analytics has the potential to assist in formative assessment. So far there has not been enough evidence collected to prove this potential support. Thus, many have reservations about the connection between the results of learning analytics and formative assessment models. If the results from learning analytics don’t match well with formative assessment approaches, teachers may be reluctant to trust, understand or use those insights to guide their teaching. This issue is addressed in a recently published study which introduces…

New Pub: ChatGPT in Education

Journal, New Pub, Research Methods

Early studies on the usage of ChatGPT in educational settings have reported substantial learning gains from ChatGPT applications. But how valid are these studies? Is using ChatGPT in education really as effective as it seems? A newly published paper takes a deeper look at key findings from past debates about media and teaching methods to reveal frequent conceptual challenges that arise in studies about the effectiveness of ChatGPT. When researchers compare different types of media for learning, they sometimes mix up the effects of the teaching style with the features of the technology. If the instructional methods and the technological features are confused with one another, it makes it difficult to be able to interpret the actual effect of ChatGPT. To help pinpoint the conceptual difficulties of these efficacy studies,…

GREAT Project – European Conference on Games Based Learning 2025

Conference

On 2.10.2025, Jane Yau presented on behalf of the GREAT project team the following paper virtually - THE REACH OF DIGITAL GAMES AND THEIR POTENTIAL AS GLOBAL COMMUNICATION TOOLS Abstract: This paper examines the potential of digital games as communication tools to reach global audiences, extending beyond established cultural and geopolitical divides. It shows the empirical data gathered in our EU and UKRI-funded Games Realising Effective and Affective Transformation (GREAT) project, where we collaborated with several organizations to investigate this potential. Namely, a significant case study called Play2Act was undertaken in collaboration with the United Nations Development Programme (UNDP), which forms the focus of this paper. The aims of this study were to find out how much of the world’s population could be reached via digital games and how…

PhD Defense: A Triumph in Learning Analytics: Congratulations, Dr. Atezaz Ahmad!

Award, PhD defense

The entire EduTec team warmly congratulates Atezaz Ahmad on his remarkable journey, as he has successfully defended his PhD thesis and now holds the distinguished title of Dr. Atezaz Ahmad. In a compelling and rigorous defense, Atezaz presented his groundbreaking research, titled: “Uncharted Territories: Learning Analytics Indicators from a Learning Design Perspective”. His PhD dissertation explores the intersection of Learning Design (LD) and Learning Analytics (LA) and addresses the long-standing challenge of their limited alignment. While LD focuses on structuring meaningful learning activities, LA provides data-driven insights into learning processes and outcomes, yet their connection has often remained fragmented. To bridge this gap, the thesis introduces the Learning Analytics and Design Alignment (LADA) framework, a comprehensive reference model that explicitly links LD principles with LA practices by connecting learning goals, activities,…

New Pub: Design, Development and Evaluation of HILA

Artificial Intelligence, Keynote, Learning Analytics, Publication

How can AI-supported learning analytics be integrated into educational processes in a significant way? How can they be designed, tested and further developed to effectively improve teaching and learning practices? These questions were addressed by Hendrik Drachsler in his keynote at the Learning AID 2024 in Bochum, which has recently been published in the conference proceeding “Learning Analytics, Artificial Intelligence und Data Mining in der Hochschulbildung”. In his keynote, Hendrik stresses the importance of content-specific applications that address genuine educational needs and are supported by empirical evidence demonstrating their effectiveness. The key to fostering adaptive and sustainable learning experiences is to understand and accommodate learners’ individual needs. Hendrik argues that technological progress alone is not sufficient to improve education. His ongoing research shows that AI-supported learning analytics can only bring…

A Heartfelt Welcome to our New Colleague Sricharan Sammeta

Team

We’re happy to extend a warm welcome to a new addition to our extended team, Sricharan Sammeta, who has just started this September for the Educational Computer Science unit of DIPF and will be working closely with us. Sricharan completed his Master of Engineering in Mechatronics at the Technische Hochschule Rosenheim, where he focused on applying artificial intelligence and machine learning to solve complex engineering and data-driven challenges. Over the past years, he has worked on projects that involved implementing core machine learning and AI concepts - from deep learning and generative AI to MLOps and multi-agent LLM systems. His work has focused on transforming advanced AI methods into scalable, real-world applications using platforms like AWS and GCP. During his time at DIPF, Sricharan plans to develop AI-powered tools designed…

New Pub: TBA at BEA 2025 Shared Task: Transfer-Learning from DARE-TIES Merged Models for the Pedagogical Ability Assessment of LLM-Powered Math Tutors

New Pub

In the BEA 2025 Shared Task on Pedagogical Ability Assessment of AI-Powered Tutors, the goal was to evaluate how well LLM-based math tutors support students. The task focused on four aspects of feedback: spotting mistakes identifying where the mistake happens giving guidance providing actionable suggestions For our submission, we built on FLAN-T5 models with a multi-step training pipeline. In addition to standard fine-tuning, we used model merging (DARE-TIES) to leverage information across all four labels – and saw clear improvements over plain fine-tuning. Our models achieved F1 scores between 52 and 69 and accuracies between 62% and 87%, ranking 11th, 8th, 11th, and 9th across the four tracks. Link to the paper: Link
