The author started instruction for the course in 2018 using the traditional classroom lecture method using the learning management system (LMS) "Blackboard" (Bb). However, the assessment approaches and lessons learned apply to other LMSs. The course migrated to a hybrid delivery in 2019. The LMS and video conferencing (Zoom) technology facilitated the migration in delivery methods. This trend continued, and the course went entirely online in the Spring of 2020 with the onset of the Covid-19 pandemic. During this period in 2020, the author became aware of the “flipped classroom” delivery method. [14] The syllabus was reworked to move the lecture material out of the classroom into video presentations ranging in length from 10 to 45 minutes. [13] Each module was standardized around pre-class reading, videos, practice quiz sets, and a pre-class quiz. The out-of-class material was screened using the Bloom taxonomy to limit the associated cognitive levels to remember, comprehend, and apply, as discussed below. The class sessions were recorded and then edited using Adobe Premiere Rush video editing software mainly to eliminate dead spells and sped the play rate to 125% of the

original. Breaks in the material were flagged with PowerPoint slides to allow the students to manually select portions of the video to watch relevant to them. This reduced playtime on average from 90 minutes to 40 minutes. At the end of each week, an online assignment incorporated all the material for the module and is discussed further below. Also, the students reflected on their experience and learning attainment in a weekly journal submission. An end-of-semester survey used a Likert scale, focusing on their perceived ability to solve complex

problems in engineering economics. As of 2021, the course was asynchronous, with several students unable to participate in the lectures either due to other class conflicts or time-zone issues. At the end of the semester, 25 hours of edited class video had been produced, with another 15 hours of associated pre-class videos also produced.
