In fact, an engineering physics program, together with courses, could be viewed as auniversal donor 1. Fundamental concepts are usually covered in introductory engineeringphysics course. However, it was reported in a recent 2005 case study that some 10 to 15% ofsenior engineering students still have confusion about the difference of energy and temperature 2.The finding is consistent with an earlier 2000 report that some students identify movement ofelectricity and energy transfer as material flows, completely

Some examples include assuming unrestrained rotation at every joint of a truss, exactly straight members, or perfectly rigid Page 11.1225.2 diaphragms.

is that moving to remote and virtual access to laboratoryhardware leads to significant changes in the learning outcomes of the students whoexperience this laboratory. In the face of such changes, these alternative access modes mustbe considered pedagogical alternatives, rather than simply logistical conveniences.IntroductionLaboratory classes are a key element in undergraduate engineering teaching. They serve anumber of valuable roles, such as validating analytical concepts, and providing exposure toprofessional practice 1. One of the drawbacks of laboratory classes is that they are expensive,in terms of both time and money. Another drawback is the significant logistical challenge ofscheduling access to hardware for potentially large groups
