security become ever more importantto Americans, engineering schools that have not traditionally focused on energy are moving toaddress the topic more formally. At Baylor University, an “energy core” of technical electives isbeing developed, including courses on wind energy, solar energy, power systems, turbines andcombustion engines. This paper documents the authors’ observations on the use of the TRNSYSsimulation software package in a senior/graduate elective on solar energy. The paper givesexamples of the types of projects students do using TRNSYS, how it can be used in theclassroom, and some suggestions for educators considering its use in future courses.Comparisons are made between projects completed using general-purpose numerical

A modified version of this approach, however, can easily be used at all levels of themechanical engineering curriculum. This laboratory’s development process began by writing asuccessful proposal for outside funding in order to create a hands-on teaching laboratory. A two-semester long, open-ended project was utilized, a process which required the students to come upwith creative approaches to problem solving. Consequently, a full-cycle learning experience tookplace. The students began with

SoftwareProgrammable logic software and high-level language compilers for microcontrollers aresupplied by hardware vendors. They are usually packaged as a part of an IntegratedDevelopment Environment (IDE), which enables a project to be created and simulated, andfinally the hardware programmed. In many cases these are usually available free of charge,especially for educational use. A very significant factor for faculty is academic support for thesoftware in regard to the course textbook. A textbook that supports the chosen software by wayof examples and tutorials is viewed very positively by the students. In fact, given that thesoftware is often free, this may be the deciding factor for software selection.In terms of programmable logic, the most widely

Institutions seeking accreditation usually go through hurdles in finding multiplemethods of assessment and to map them to the objectives of the programs. Continuing studentperformance is traditionally assessed by quantitative method in which numerical scores areassigned on quizzes, home works, projects and tests. ABET considers this as a single assessment,as it is an acceptable indicator of performance of the graduates in the future.

Does this new information help thestudent to become a better general electrical engineer? Does the new information helps thestudent to prepare, executes, and demonstrate a better final senior design project? Does thestudent have to take the communication course in order to satisfy the

assessment of student performance in a course directly tied to a specific program outcomeis referred to as an embedded indicator. This type of information reflects a direct assessmentmethod and can provide quite useful information. To be clear, embedded indicators do not referto course grades, and we will discuss those separately. Embedded indicators relate to studentperformance on a particular activity, such as an exam question, project, or report, and correlate toa particular outcome. Courses that are more relevant to a particular outcome, such as shown inTable 1, are better choices for utilizing embedded indicators. It is important for the score of theactivity to directly correlate to a specific outcome. This may take a little time on the part of
