The central theme of this webinar is computer-based tools made broadly accessible to students, educators, researchers, and lay people. Major platforms discussed include graphical user interfaces (GUIs), interactive notebooks (e.g., Jupyter Notebooks and MATLAB Live Scripts), and GitHub repositories. These tools have been used in instructing and engaging undergraduate chemical engineering students, preparing faculty for using these tools, training undergraduate and graduate students for computational research in science and engineering, and introducing lay audiences to chemical engineering concepts in informal learning environments outside of the classroom. These and other resources are available in a collection of open-source materials available at http://github.com/ashleefv. Also in this collection is an open-source learning module that the presenter created and packaged (with support from CACHE) for an upper division/graduate elective course, focused on practical computational science and engineering concepts, including GUI design, version control, LaTeX, MATLAB, Python, and open-source and reproducible research computing. The presenter also developed and co-led a session at the 2022 ASEE/AIChE Chemical Engineering Summer School featuring MATLAB and Python interactive modules for computations throughout the ChE curriculum. A subset of these resources will be highlighted in the webinar.
