[publication] Sieben Mythen der KI-Nutzung #tugraz

Unser Beitrag zu „Sieben Mythen der KI-Nutzung“ hat viele Reaktionen hervorgerufen und nun wurde er auch in die Zeitschrift „Die Österreichische Volkshochschule“ aufgenommen.

Abstract:
Wer das Internet nutzt, kommt im Frühjahr 2026 nicht um Anwendungen generativer Künstlicher Intelligenz (kurz KI) herum. Suchmaschinen bieten neben Links standardmäßig KI-generierte Antworten an, Chatbots unterstützen bei der Buchung von Websites, Schüler:innen lassen sich Tests passend zu den Arbeitsblättern der Lehrer:innen generieren usw. – Doch nicht alles, was uns die KI-Anwendungen liefern, wie wir sie nutzen und ihre Ergebnisse verstehen, ist zutreffend und unproblematisch. Das liegt auch an Missverständnissen darüber, wie KI-Anwendungen funktionieren. Aus unserer Sicht – es gibt dazu noch keine empirische Evidenz – verdienen folgende sieben Aussagen besondere Aufmerksamkeit, insbesondere auch im Kontext von Bildung, Schule und Hochschule:

  1.  KI-Anwendungen sind neutral, objektiv und vorurteilsfrei
  2.  KI-Anwendungen arbeiten logisch
  3. KI-Anwendungen denken und lernen wie Menschen
  4. KI-Anwendungen sind empathisch
  5. KI-Anwendungen sind ökologisch und sozial problemlos
  6. KI-Nutzung ist rechtlich einwandfrei
  7. KI-Anwendungen machen Wissen und Kompetenzentwicklung überflüssig

In diesem Beitrag möchten wir diese als „Mythen“ bezeichneten Aussagen beschreiben und aufzeigen, dass und warum sie nicht zutreffend sind. Damit möchten wir einen zukünftig fundierten Umgang und durch die Beschreibung von KI-Mythen Forschung dazu initiieren und unterstützen.

[publication] Generative AI Chatbots in Secondary Mathematics Education: Development and Implementation of a Dynamic Large Language Model-Based Learning Assistant for Quadrilaterals #tugraz

Our contribution titled „Generative AI Chatbots in Secondary Mathematics Education: Development and Implementation of a Dynamic Large Language Model-Based Learning Assistant for Quadrilaterals“ is now published.

Abstract:
As artificial intelligence becomes more and more a part of education, the challenge is not about having access to generative tools, but about connecting them with the goals of the curriculum and the needs of the classroom. This chapter presents the design and evaluation of a large language model–based chatbot developed specifically for teaching quadrilaterals in lower secondary mathematics. The chatbot integrates fine-tuning with retrieval-augmented generation (RAG), combining accurate, curriculum-aligned content with flexible, conversational support. The chatbot allows learners to ask conceptual questions, solve problems step by step, receive guided hints, and generate flashcards or exercises of varying difficulty. A hybrid routing mechanism selects the most appropriate response strategy based on user intent. Evaluations using both isolated prompts and multi-turn dialogues demonstrate that the hybrid system significantly outperforms standard LLM baselines in terms of accuracy, consistency, and pedagogical suitability. A classroom trial with 20 students confirmed the tool’s usability and effectiveness; students reported high satisfaction and meaningful engagement. This study demonstrates that, with careful content and architectural structuring, generative AI can enhance student learning while supporting differentiated instruction. Future directions include scaling the approach to other topics and incorporating multimodal capabilities.

[publication] Generative AI literacy across education and business: competencies, obstacles, and benefits—a systematic literature review #research

Our article, which we really worked on for a long time, is published right now with the title „Generative AI literacy across education and business: competencies, obstacles, and benefits—a systematic literature review„.

Abstract:
This systematic literature review analyses AI literacy, focusing on the required competencies for, the obstacles arising from, and the benefits of, Generative AI (GenAI) in the fields of education and business. The analysis uses the PRISMA 2020 methodology with data from the SCOPUS and ERIC databases. A total of 538 articles were identified; of these, 206 were included after the full-text screening phase. Of those 206, only 33% (education) and 29% (business) were based on empirical research, highlighting the predominantly conceptual state of research. Using a combination of inductive coding and GenAI (ChatGPT-4o) validation, we identified AI literacy as a multidimensional concept comprising technical competencies (e.g. algorithmic literacy and prompt engineering), personal and interpersonal competencies (e.g. adaptability and collaboration), and ethical and critical thinking competencies (e.g. awareness of bias and ethical reflection). While educational literature emphasised pedagogical applications such as adaptive feedback and inclusive curriculum design, business research focused on process automation and data-driven decision-making. Top three identified obstacles included hallucinations, ethics and plagiarism, which manifested differently in contexts such as student assessment and personnel selection. Addressing these challenges will require targeted training modules, ethical governance structures, and institutional support in the form of faculty development programmes or workplace reskilling initiatives. Top three identified benefits of GenAI literacy training are described as critical thinking, personalized teaching and learning and personalized feedback across sectors.

[poster] A Whitepaper on Evaluating GenAI Innovation in Higher Education #edmedia26

This year, we present a poster about „A Whitepaper on Evaluating GenAI Innovation in Higher Education“ at EDMedia 2026.

Generative artificial intelligence (genAI) is increasingly shaping higher education by enabling new forms of content creation, assessment, learner support, personalization, and synthetic media. A whitepaper now presents a practice-derived framework developed through a cross-case synthesis of nine diverse GenAI implementations at Graz University of Technology. Analyzing projects ranging from AI-generated content to RAG-based chatbots, recurring decision points and risk patterns were identified to formulate a five-phase, non-linear evaluation model.

[publication] Enhancing Synchronous Collaborative Learning with AI-Supported Audience Response Systems: The EchoQuiz Approach #ARS #AI #tugraz

Our publication about „Enhancing Synchronous Collaborative Learning with AI-Supported Audience Response Systems: The EchoQuiz Approach“ is now online available.

Abstract:
This paper introduces echoQuiz, an open-source, AI-supported Audience Response System (ARS) designed for synchronous university (online) teaching with open-ended questions. The system follows a two-phase interaction model: In the quiz phase, students/learners submit their responses and then rate their peers’ responses. In the echo phase, the instructor highlights one response for group reflection, with all responses remaining anonymous. To ease the interpretation of open responses, the lecturer can be assisted by an AI system during live sessions. Developed with an Educational Design Research (EDR) approach, echoQuiz was piloted in synchronous university courses with a total of 62 participants. Survey results show high motivation and moderate perceived learning gains. The findings suggest that free-text interaction, supported by AI, can enhance engagement and adaptability in digital classrooms.

[publiation] AI-Powered Chatbots for Education Using RAGs #tugraz

Our publication about „AI-Powered Chatbots for Education Using RAGs“ got published right now.

Abstract:
This study examines the use of Retrieval-Augmented Generation (RAG) in AI-powered educational chatbots, focusing on embedding efficiency, large language model (LLM) performance, and context integrity. Implemented within the MOOC Informatik-Fit at TU Graz, the system supports scalable, curriculum-aligned self-paced learning. Three embedding models were evaluated, with text-embedding-ada-002 offering the best balance between semantic quality and cost-efficiency. Subsequently, three LLMs—GPT-3.5 Turbo, GPT-4o, and GPT-4o mini—were compared, revealing GPT-4o mini as the most cost-effective option while maintaining high accuracy and contextual coherence. Ethical robustness was assessed using 30 adversarial prompts, demonstrating strong resistance to jailbreaking in both GPT-4o and GPT-4o mini, supporting their suitability for secure and pedagogically reliable MOOC applications.
The paper also presents a replicable framework for the implementation of RAG-based systems, with the objective of promoting personalized, ethical, and accessible digital education on a large scale.

Blogpost on „New Report: Seven Myths of AI Use – A Critical Perspective on Generative AI“

Thanks to Stefanie, who published a blogpost about our „Seven Myths of AI Use – A Critical Perspective on Generative AI„:

These days, people can hardly use the Internet without running into generative AI—yet many everyday beliefs about “how AI works” are inaccurate in ways that matter especially for education, argues the position paper “Seven Myths of AI Use”. It was published by a team of six Austrian researchers: Sandra Schön, Benedikt Brünner, and Martin Ebner from Graz University of Technology (TU Graz), Sarah Diesenreither and Georg Krammer from Johannes Kepler University Linz, and Barbara Hanfstingl from the University of Klagenfurt. At a time when we start to contemplate futures of “a country of geniuses in a datacenter” (Dario Amodei), this report summarizes some of the most prominent concerns towards generative AI.
