\r\n\r\nGenerative AI has become a part of students' everyday working life. If used without guidance, GenAI can cause over-reliance and leave students with a distorted sense of what they have actually learned. Most research and practice have focused on how we can scaffold students' GenAI use, for example through prompts, guardrails, or redesigned tasks. This talk asks a simpler question that has received far less attention. When should students be allowed to use AI so that it helps their learning?
\r\n
\r\nIn this lunch&LEARN session, Janne Rotter turns to a question that's been largely overlooked: not how, but when should students be allowed to use AI for it to actually support learning? Janne will present findings from a study of 105 university students comparing three conditions: unrestricted AI access, no access at all, and a \"timed\" condition where students could only turn to AI after first attempting the task on their own.
\r\n
\r\nDrawing on multiple pedagogical theories to build a decision rule for when access should open up, the results show that students in the timed condition outperformed those with unrestricted access on an objective post-test, and had a more accurate sense of their own understanding, without an explicit metacognitive prompting. Compared to withholding AI entirely, timed access also seemed to reduce task errors and time spent on task.

Chirality is omnipresent in nature through a fundamental coupling between chirality and angular momentum. Despite extensive experimental evidence, the underlying mechanisms of this coupling remain debated. Here, we will explore how chiral magnetic textures can be stabilized in altermagnets, a new class of magnetism. Turning to structurally chiral magnetic molecules, we will show that chirality is directly linked to their intrinsic magnetic moments. Bringing both together, we will discuss how molecular design can control spin phenomena at hybrid chiral molecule-magnet interfaces. Our findings pave a pathway towards functional \"chiraltronic\" devices – turning a fundamental puzzle into a technological opportunity.
