Background
Over the past few years, there has been a parallel development in the use of the internet and technology for teaching purposes. The Flipped classroom model (FCM) used by the instructor aims at spending more time interacting with students rather than lecturing them. There are very few studies about the effectiveness of FCM on student performance and perception as compared to the traditional lecture in colleges of medicine. This study evaluates the effectiveness of the FCM on the academic achievement of students in terms of increased performance and perception as compared to the traditional lecture the medical students in Al-Neelain University-Sudan.
