Chemical Engineering Screencasts
John L. Falconer, Garret D. Nicodemus, Janet deGrazia, and J. Will Medlin
Screencasts are videos made by digitally recording a computer screen (often a Tablet PC that can be written on) with accompanying narration. More than 430 screencasts are available online for chemical engineering courses (engineering calculations (computing), material and energy balances, fluids, heat transfer, thermodynamics, kinetics/reactor design, and separations/mass transfer) at and on iTunesU. These screencasts have been watched more than 43,000 times in their first year of availability and downloaded more than 41,000 times from iTunes U. Screencasts can be prepared quickly and used to present solutions to example problems, software tutorials, exam reviews, explanations of concepts, and mini-lectures. Most are less than 10 minutes in length, and many are about 5 minutes long. Feedback from students in a number of courses has been overwhelmingly positive; students indicated that the screencasts were extremely helpful for learning. They also have the potential to save instructor time. These screencasts can be viewed on computers, tablets, or smartphones.
