Teaching and Learning Project 2025–2026 funded by the International Centre for Teaching and Learning (ICTL) at Queen Mary Engineering School (QMES) (£1,350). This scholarship project investigated the impact of immediate explanatory feedback delivered through Kahoot! quizzes compared with delayed written feedback on undergraduate engineering students' learning and perceptions. The project aimed to develop and evaluate a scalable, technology-enhanced formative assessment approach to enhance student engagement, understanding, and feedback effectiveness. The project was successfully completed, with outcomes accepted for presentation at the Advance HE Teaching and Learning Conference 2026 (Flash Feedback: A Purposeful Digital Approach to Transform Formative Assessment).
