This study examines the effects of a pre-service teacher training on inquiry-based learning (IBL) in history education. This training consisted of a workshop and an assignment that required student teachers to prepare and implement an IBL activity during their teaching internship. The findings reveal that student teachers found the workshop valuable, and afterwards felt significantly more capable to organize IBL activities in the classroom. The authors found that the workshop was also able to convince student teachers of the value of IBL. After its ending, almost all student teachers indicated that they mainly wanted to use sources for conducting full-scale investigations, whereas, previously, about half of them had held a different opinion.
