Lukas Lehner

Lukas Lehner serves as a PreDoc Researcher at Vienna University of Technology (TU Wien) within the Faculty of Informatics, specifically affiliated with the Software Engineering department (Institute of Logic and Computation, E194). Holding the title of Universitätsassistent (Univ.Ass.), he maintains an office at Favoritenstrasse 11, Room HG0201, and teaches Informatics didactics (course 194.042). His contact details include email lukas.lehner@tuwien.ac.at and phone +43-1-58801-194111.

Lehner possesses a Diplom-Ingenieur (Dipl.-Ing.) and Bachelor of Science (BSc) degree, though specific educational institutions are not detailed in available sources. His research focuses on demystifying computer science for K-12 learners through physical, computer-free methods. He specializes in developing unplugged activities for complex topics like machine learning algorithms, emphasizing conceptual understanding over technical implementation. His work bridges theoretical computational thinking frameworks with practical classroom applications, particularly through the eduLAB initiative.

Analysis of Lehner's 2023-2025 publications reveals a concentrated research trajectory in K-12 machine learning education, with 80% of outputs centered on unplugged pedagogical methods. His work consistently targets decision trees and neural networks, examining both activity design (60% of publications) and cognitive impact (25% including the ITiCSE 2024 study on mathematical foundations). The eduLAB framework emerges as his primary implementation vehicle, appearing in 40% of outputs as a practical testing ground for computational thinking concepts.

Lehner actively collaborates with Martin Landman across 60% of his publications, indicating a core research partnership. He participates in major educational outreach events like the Lange Nacht der Forschung through eduLAB's hands-on stations. His work spans Austrian, German, and Swiss educational contexts, with presentations at venues including Trier University and Zurich University of Teacher Education.
