Student Evaluations of U.S. Chemical Safety Board Case Study Videos Using a ChE Process Safety Assignment

A ChE process safety assignment using case study videos produced by the U.S. Chemical Safety Board (CSB) is described. Study of student perceptions of video quality and effectiveness of 25 CSB videos identified a number of entries highly-regarded by students which would make good choices for in-class discussion/assignments. Student ratings of videos' visuals and effectiveness had a highly statistically significant positive correlation, confirming visual ethos theory from contemporary communication rhetoric literature.
