Dr. Nicodemus has taught a variety of different classes in chemical engineering at the University of Colorado Boulder. He has helped build the inventory of screencasts, conceptests and simulations in chemical engineering courses. His interests have been in developing active learning methods and incorporating technology in the classroom.

The teaching/learning resources for chemical engineering on havebeen greatly expanded and improved to make them more useful for both students and faculty.The website now contains more than 1,250 screencasts, which are short videos made by screencapture of a tablet PC screen. These screencasts provide brief, focused mini-lectures that can be usedas replacements or supplements of activities that would typically occur in a classroom (e.g., toimplement flipped classrooms). They also present solutions to problems and present software tutorials.The use of these screencasts is inherently interactive because students can work through problems attheir own pace, and they can pause, rewind, and skip sections of the screencast. To further increaseinteractivity, screencasts were prepared that allow students to answer questions during a screencast totest their understanding and receive tailored explanations when they select an answer. That is, theanswers within the screencast are linked to other screencasts. The screencasts, which are now availablefor ten chemical engineering courses, but can also be used by students in other engineering majors,were played/downloaded more than 2.2 million times in the last twelve months. More than 100 of the original screencasts were replaced based on outside feedback in orderto correct errors or improve presentation of the material. For many of the courses, thescreencasts were indexed for additional textbooks, and more than 400 screencasts were closedcaptioned. Also, many of the screencasts are now linked (within the screencast) to otherscreencasts to guide students in their use. Screencasts were also added that make use ofinteractive simulations to explain concepts. Assessments were carried out to study howstudents use screencasts and the effect of screencasts on learning. More than 65 interactive Mathematica simulations were added to the website. They allowthe user to change variables and observe the effect on the system behavior, and they do notrequire Mathematica software. Links were also provided to active-learning course packagesthat we prepared in thermodynamics and material and energy balances.P
