Applied Education Technologies

Im November bot TUM LearnLabs zwei besondere Veranstaltungen an: einen spielerischen Informatik-Workshop für Kinder im Rahmen des TUM-Ferienprogramms und ein erstes Lehrertraining für ein Kollegium aus Eggenfelden. Während die Kinder mit Rätseln, Verschlüsselungen und Bastelaufgaben Informatik entdeckten, erhielten die Lehrkräfte praxisnahe Einblicke in analoge und digitale Aktivitäten für ihren Unterricht. Beide Tage zeigten, wie leicht und motivierend der Zugang zu Informatik gestaltet werden kann. Die positive Resonanz bestärkt uns, solche Angebote weiter auszubauen.

At the 25th Koli Calling International Conference on Computing Education Research in Koli, Finland, Patrick Bassner presented our paper Towards Understanding the Impact of Context-Aware AI Tutors and General-Purpose AI Chatbots on Student Learning, coauthored with Anna Lottner and Stephan Krusche. In a randomized, mixed-methods study with 33 students, we explored how learners tackled the Burrows-Wheeler Transform with the context-aware Iris tutor, a general-purpose chatbot (ChatGPT), or no AI support. Performance converged across conditions, giving us a strong baseline, while Iris users showed an encouraging uptick in learning scores alongside slightly longer focus time. Interviews brought energetic feedback: context-aware guidance removed friction, guardrails kept learning on track, and students openly discussed how time pressure, trust, and verification shaped their choices.

We are excited to share that our paper, “LLM-Based Multi-Artifact Consistency Verification for Programming Exercise Quality Assurance”, was presented at the Koli Calling International Conference on Computing Education Research in Koli, Finland (November 13–16, 2025) Auto-graded programming exercises in platforms such as Artemis rely on several interconnected artifacts: problem statements, templates, solutions, test suites, and learning objectives. When these artifacts drift apart, students face confusing tasks and instructors spend time on manual QA. Our work introduces an ontology-driven, LLM-powered approach to keep them aligned:

At Koli Calling 2025, multiple members of our group contributed research and review service to the community. The conference once again highlighted how much careful, constructive feedback elevates the work being shared, from early-stage ideas to polished studies ready for publication. We are thrilled to share that Patrick Bassner received the conference’s “Superb Reviewer” recognition for constructive, detailed, and relevant feedback on multiple submissions. Being acknowledged for both scholarship and service underscores how much the Koli community values supportive, actionable reviews that help authors strengthen their work, and we appreciate the trust and collaboration across the program committee and presenters.

Wir beteiligen uns erneut mit einem Program am Girls’Day! Tauche ein in die spannende Welt der Informatik und lerne die beeindruckenden Geschichten der weiblichen “Hidden Figures“ kennen – Pionierinnen, die die digitale Welt geprägt haben. Erlebe selbst, wie kreativ und vielseitig Informatik sein kann, während unsere Informatikstudentinnen und Informatikstudenten dich durch einen abwechslungsreichen Tag voller spannender Aktivitäten begleiten.
