Work In Progress: "Explain It To Me"

The ubiquitous on-line delivery and assessment of personalized tasks and homework problems to students in pre-engineering physics courses has had considerable positive impact promoting student achievement. The reasons include instant feedback on the correctness of the solutions and the ability to interact quickly and efficiently with fellow students and teaching staff. Still, many and especially less well prepared students have considerable difficulty in understanding the assigned problems. The current work investigates the impact of providing students video explanations designed to approximate personalized one-on-one tutorial sessions for a set of representative problems. Initial results show significant improvement in the students´ problem solving ability
