Clearly additional avenues must be pursued.

In general, students can learnabout many communication systems, but have no opportunity to actively learn first-handthe performance trade-offs involved in designing a system. For that reason, a new courseusing a combination of lectures and multiple computer assignments has been proposed toprovide a practical view of communication systems using computer modeling andsimulation. The course assumes that students only have a background in signals andsystems. Therefore it includes a lecture covering the relevant concepts needed

Students who enroll for this course, however, expect to learn about digitalsignal processor hardware and how to program it. Due to time limitations, it is impossibleto teach both aspects thoroughly.

Traditional lectureformat teaching methods sometimes fall short of conveying the complex analysis and designprinciples that need to be mastered in reinforced concrete design course. One of the methods ofreducing this short fall is to use simple animated virtual models, which demonstrate basicstructural design concepts that can be used to enhance the students understanding.

Typical juniors at FrenshipHigh School are students who are unsure of what field of work they want to enter and areunsure of their post-secondary educational needs. Individually advising 200+ students onthe world of work can be daunting for one counselor. However, in groups of 15-18students in a computer lab situation, students were introduced to E-COACH.

then incorporated into a computer code to calculate total relativedisplacement under arbitrary history of shear loading. MotivationIt is hard to find structural elements in engineering applications that would not have anyjointed connections. The search for joints’ accurate modeling has been on-going for yearsbut with limited success. The latter is mainly attributed to the complexity of physicalprocesses taking place in the contact region when a joint is subjected to loading. Forexample, a contact between two surfaces always results in energy dissipation caused byfriction in shear micro-displacements. It leads to a highly non-linear behavior of a joint.The other challenge is related to the fact that the
