Additionally, within an educationalframework, enhanced interaction between engineers and managers would provide for a moreeffective relationship in industry. This paper describes this protocol study in detail along withobservations of students’ communication. Data is presented, conclusions drawn andrecommendations given. It is believed that certain areas that contribute to the development ofthe skill of communication across fields are lacking in engineering curricula. This studyattempts to identify these areas to provide insight into the nature of risk communication problemsin industry.1 IntroductionIn the

-Madison, WI Abstract Many digital signal processing (DSP) topics are difficult for undergraduates to internalize, but studies have shown that demonstrations and laboratory experiences can facilitate the process. In the past, many barriers prevented including real-time DSP hardware in an undergraduate curriculum. This paper describes a pedagogical model the authors have developed which includes theory, demos, lab exercises, and real- time DSP experience using Matlab, C, and real-time DSP hardware that overcomes the barriers. This model has been very successful.1 IntroductionA common complaint heard from electrical engineering (EE) undergraduates

For each textbook chapter, a study question was posted to an online bulletin board. Studentswere required to complete the study question any time during the assignment week. The studyquestions asked students to connect content of the textbook chapter to personal experience or toconnect the content with an online article linked to the question. The study questions typicallyrequired answers of 1 to 3 paragraphs in length.

Finally, we provide conclusions that indicate on how otherinstitutions might use RP technology in their design curriculum.1. INTRODUCTIONRapid Prototyping, as defined by Cooper 1, is the layer-by layer fabrication of 3-dphysical models directly from a computer aided design (CAD). For the last three yearswe have been using a rapid prototyping (RP) machine to facilitate design education at theUS Air Force Academy. The specific type of RP technology we have employed is oftenreferred to as a 3-d printer and is described in more detail in a following section. The RPtechnology has been used to enhance two of our courses in particular: 1) SophomoreIntroduction to Design

However,due to the recent ABET requirements and other curriculum issues, many universities areconsidering to integrate these courses into a single one. In fact, a common recent trend [1] is toteach an integrated course, which includes concepts of statics and basic solid mechanics. Otherexamples include the integration of technical drawing and solid modeling, dynamics andintroductory vibrations, finite element analysis (FEA) and machine component design andsystem dynamics and

The objectives associated with this research program are four-fold: 1) toreach a student population that has a great variety of learning styles, 2) to increase overallmotivation in the topic area, 3) to create a more active learning environment and 4) to presentproblems which are open ended and therefore have no single “right” solution.

Do I mean that we go out and teach science to shopkeepers, lawyers, consultants, and construction workers? Not entirely. To engage in dialogue is to listen as well as to speak. While there is great need for the public to have a better understanding of science, and we should promote this in every way possible, there is as great a need for scientists to have a better understanding of the public. 1 (my emphasis)Lane argues here for a reciprocal understanding between the engineer and society, a dialogue inwhich the engineer listens to society’s needs and interprets them in the design of new andbeneficial

ofengineers is to protect the public safety and welfare at large. After all, this is the factor that setsengineers apart from other professions. However, many engineers do not recognize that theycannot wholly satisfy that responsibility unless they become active participants in thedevelopment of public policies. By utilizing their unique set of skills, talents, and educationalexperiences, engineers can affect the outcome of policy decisions in a major way. It is theresponsibility of their educators to help them realize their importance in this big picture. References 1. Accreditation Board for Engineering and Technology (2001).

The challengewas to develop a project that was realistic, incorporated all of the course topics, and containedthe appropriate level of complexity.

. IntroductionWhen I started teaching DSP last year, I chose LabVIEW as the computer tool for hands-onexperiences and demos. The decision was against the common trend, for MATLAB has becomethe de facto standard for numerical computation in signal processing 1. This uncommon decisionwas taken because of two major reasons: i) My previous experience with LabVIEW 2-6 has beenvery rewarding and I would like my students to have LabVIEW programming skills in addition toMATLAB programming skills they acquire in their Introduction to Engineering class at thefreshman level and in Linear Systems at the sophomore level. ii) It was my contention that“processes that [are best] describe[d in terms of] what happens to various inputs to achieve anoutput, so easily depicted
