This paper explores the effectiveness of various video based learning methods. In recent years the flipped classroom has emerged as an innovative teaching-learning process. In a flipped classroom, study materials are made available to students for self learning before class starts and class hours are utilized for student teacher interaction in a variety of ways. In this research work we experiment with three broad scenarios to facilitate learning: a) delivering the lecture live and providing the entire recorded video of the class to the students, b) delivering the lecture live and providing short videos of the main concepts discussed in that class, c) recording lecture videos and making them available prior to the actual class (flip classroom model). We evaluate the impact of these three scenarios. For that we use observations, questionnaires, and interviews of both instructor and students for a semester course in Digital Image Processing. The results show that recorded videos are useful for students. Among these scenarios the students find the methodology of the delivery of the live lecture followed by short recorded video summary as the most effective way for learning.
