education, and assessment methodologies31-32. For some engineering programs, ablended instructional environment could provide the initial step towards the development of anonline learning experience for students and faculty31-32. However, additional research into theblended learning environment for engineering students’ learning, satisfaction, and retention isneeded to assist these programs in using the technology wisely31-32.PurposeThe purpose of the present study was to compare blended instruction to a traditionally taughtsophomore level chemical engineering material and energy balances course (a traditionalintroductory course in the chemical engineering curriculum). Specific research questions to thisstudy were: 1). How does the use of
