way to capture interactivity fromstepping through an animation or multi-step example to correctly answering multiple choice ortrue and false questions. However, online homework provides more advanced metrics to capturestudent’s problem-solving skills. Numerous platforms have been in development for years withmath and science courses having more tools and options than engineering courses [1-4].Online homework is synonymous with terms such as auto-graded problems, and these tool havebecome common throughout science, technology, engineering, and mathematics (STEM) [5-9].By providing instantaneous feedback to students, auto-graded problem capture some of the mostimportant tenets of deliberate practice [10-13]. Other learning frameworks also
students analyze the Haber-Bosch process in theirChemical Plant and Process Design I course through individual homework assignments(Appendix A7). The last two quarters of their senior year, the students are already working inteams of four students on their capstone design project (which is not the Haber-Bosch process)and in their capstone unit operations laboratory courses. Instead of assigning additionalteamwork, the Haber-Bosch process analysis is continued in individual homework assignments.Students develop process simulation skills in Aspen Plus by modeling the ammonia synthesisreactor-separator-recycle-purge loop and using Aspen’s process optimization tools (sensitivityanalysis and design spec) to optimize the process. They perform sizing
