What I am planning:
Interventions through a guest lecturer (entrepreneur) in non-business student groups, ex-ante-/ex-post-/follow-up-survey (3 months), control group (business students).
Aim: Generating affective learning outcomes (entrepreneurial inspiration, entrepreneurial desirability, certainty about aptitude for entrepreneurial tasks, etc.).
Even better if someone would know any evidence (or pedagogic theory) about negative effects of too long or too short excursions.
Thank you very much for any suggestion!
