Areas thatwere covered ranged from engineering design to operator training to media coverage andgovernmental responses. At SL-1, three operators were killed when they accidentally triggered asteam explosion in the reactor. There was total secrecy applied to this disaster. At Three MileIsland, there was a reactor meltdown triggered in large part by operator training and workplacedesign. The media covered the incident, in which there were no injuries, extensively and (somewould say) at times hysterically. At Chernobyl, lack of operator training and poor reactor designtriggered a massive explosion which scattered radioactive debris across half of

At the end of the semester, the students must present a team project. The project is ofsufficient complexity and workload that it is very difficult for one student to complete it alone ina semester’s time frame.To illustrate the teaching approach, the topic of distillation will be presented. In this typicalsession on distillation process design and operation, the students learn about the concept ofdistillation, how to design a distillation to achieve desired product specifications, simulate adistillation process and consider the impact of certain operating variables on its operation.By

Universities today have attained top of the line environments for “realworld” engineering application laboratory and design processes. However, students find thatdespite having a solid education of applying theory to engineering ingenuity, there is littleexposure to existing equipment. Sure, classes build a strong backbone of basic and complexprinciples on which we create designs from the ground up, but there is also value in seeing whatis already out on the market and how current products fair with the human interaction.

preference for visual learning over verbal learning [3, 4]. Charts,graphs, videos, and other graphics work much better for engineering students than text-based orlecture-based aids. Often students favor active learning techniques. This is especially true forsenior students, who are more likely to be interested in the hands-on applications of the material[4]. Active learning techniques may include activities like laboratory work, working in groups,and playing with ideas [1, 2]. Unfortunately, most classroom environments are passive settingswith students involved mostly in listening—slightly favoring reflective learners, but not stronglyhelping either style [2].

controlled to fit within a typically constrained laboratory budget, since thecost of development of a platform for a mobile robot can become fairly expensive as thecomplexity of the sensors and control system are increased, it can reach thousands of dollars. Inour case, early in the development process, this was a limitation that we had to work with. First,we try to establish which would be the best approach to follow in order to keep the cost of therobotic platform within the limits of the budget assigned to this class. Next, in order to reduce theimplementation costs we decided to use as many devices and systems that we already hadavailable in our labs, such as sensors, electronic devices, laptops, microcontroller cards andsimulators, programming

This degree requires that all students conduct adirected project as a requirement for graduation. The directed project is an applied researchproject that is more extensive and sophisticated than a graduate-level independent study and lessformal than a master’s thesis. The overall objective of the requirement is to engage each graduatestudent in a study, typically industry or business focused, which is sufficiently involved as torequire more than one semester to conceive, conduct, and report.
