Traditional lecture theatre environments present significant challenges in higher education, in light of increasingly large and diverse student populations. This small-scale study explores how blended learning through the game-based platform Kahoot! can be used to enhance the learning experience offered to students in these spaces, from the perspective of 44 final-year primary education undergraduates. An action research approach was employed with data collected from pre- and post-lecture surveys. Findings suggest that the integration of synchronous online learning in lecture theatres presented no technical difficulties and that gaming was successful in enabling active participation and interactive learning. Students valued its competitive nature, the immediacy of feedback on their knowledge and structured opportunities for further discussion. Students reported improvements in engagement, concentration and retention, although results for the latter were more ambiguous and would benefit from further investigation.
