Tablet PCs were provided to all trainees for the length of the course. Detailedhandouts were also provided to all the trainees to accommodate reading/writing learners. Thefirst half of the course followed a traditional lecture type training module, with one instructor andseveral ‘students’ to accommodate auditory learners. The instructor used PowerPoint

This paper discusses how these signals can be effectively used to teach, demonstrate, and reinforce the concepts of time dilation/compression, frequency trans- lation, spectral analysis/estimation, and aliasing.1 IntroductionKeeping our students interested and motivated is an ongoing challenge for professors today. In theauthors’ experience, we find that our students of signal processing still respond well to demon-strations that pique their curiosity or interest them in one way or another. This usually requiresinvolving their sense of hearing and/or sight in some way. For most students, tying such demon-strations to real world applications can bring signal processing theory to life

That is thereason that automating the design process through hardware description languages and softwarethat reads those languages to configure programmable logic devices has been so successful. Onthe surface, everything is cookbook and easy. Complex systems are assembled by replicatinglots of simple circuits, a process at which digital computers excel. Circuits designed by studentsin the lab for an introductory digital circuits course fall into this category of design. Once

While such interfaces may be useful in some domains, they haveclear limitations. For example, they are typically not well-suited for instruction in domainsin which solutions require complex graphics. Engineering Statics is one such domain.Solving Statics problems requires the construction of free body diagrams and equilibriumequations, two tasks which are difficult to perform with a mouse and keyboard.Here we present our efforts

computer science students understood computer function (most ofthem had not yet taken a computer architecture course), but rather that the liberal arts studentswere troubled by their ignorance while the technical students were not. Clearly, it would beuseful to provide the entire class with a basic understanding of how stored program computersfunction at a very simple level.In addition, for the purpose of the particular class, we determined that it would be useful tointroduce a few basic computer science concepts: 1. A finite set of operations can each be numbered and hence be uniquely identified by bit patterns. 2. One can often solve complex problems using algorithms consisting of a sequence of very simple primitive operations. 3

IntroductionIn typical Dynamics courses, most homework problems require the student to solve for agiven variable at an instant in space and time. The professor typically assigns a set ofhomework problems and the students solve each problem by hand. The student knowsthat his or her calculations are correct by checking answers in the back of the book.In reality, the subject of particle Dynamics is the study of motion and not the calculationof a particle’s point at a particular instance in time.

For instance, a student may be asked tosolve for the work and/or heat transfer of a process that begins at known state #1 andends at known state #2. In reality, though, the work and heat transfer vary with time asthe system moves from state #1 to state #2.
