We previously reported the advantages of using screencasts in chemical engineering courses.''' In the current paper we discuss uses of screencasts, describe their availability, present data that demonstrate how extensively they have been used, and provide additional student feedback. More than 430 screencasts have been prepared for seven chemical engineering courses: engineering calculations (computing), materials and energy balances, fluids, heat transfer, thermodynamics, kinetics/reactor design, and separations/mass transfer. Screencasts were prepared using Camtasia Studio 7 software, which captures both narration and real-time screen input. These screen recordings were edited and processed into MP4 videos that are posted online.
