Most importantly, however, at some point in the project they will have to makesome of their own decisions. There will be more than one way to attack the problem, and thestudents will have to make appropriate assumptions, research several alternatives, use commonsense and think both logically and physically in order to arrive at a practical solution. If thisproject accomplishes its goal, the chemical engineering curriculum at Penn State University willtake a step away from being a mere extension of theoretical science and a step toward being anactual preparation for a career in thoughtful problem-solving and design.1 IntroductionLike many

A top-down methodology is used Specifically, thedesigner must think in an organized fashion to generate a top-down hierarchy. Modularinterfaces are developed at top-level. Higher-level components are made up of lower-levelcomponents, with the lowest level being components that have realizable behavioral or structuraldescriptions. The design tools used in the Department of Electronics and Computer EngineeringTechnology at Arizona State University East allow the generation of this hierarchy within codeor schematic.The synthesis tool Synplicity Synplify1 allows portable behavioral VHDL code that issynthesizable and

A FORTRAN program has been written allowing the students to input their ball launchconditions to obtain the ball’s trajectory and carry distance. To accommodate the student’sanalysis needs, a standardized LS-INGRID file for the ball and club was developed (LS-INGRIDis a preprocessor for LS-DYNA). Also, FORTRAN program has been written to post-processthe data. Running these simulations on a Sun Ultra 1 workstation takes approximately 7 minutesper design iteration.I

IntroductionFixed roadway lighting plays an important part in safe driving at night. Since automobileheadlights do not light a distance that is adequate for safe stopping at night. To provide safedriving at night, different design methods for roadway lighting was developed to obtain bettervisibility and visual comfort. The first time roadway lighting were desined, it was based on theamount of light striking the surfaces of the pavement (illuminance). However, it was later foundthat the brightness of a pavement related to the amount of light that is reflected from it(luminance). Since then, it has been proved that the ability to

IntroductionThe World-Wide Web owes its existence to the Internet, whose original constituents weremainly universities. So it is only natural that the Web should abound with educationalmaterials. As universities scramble to put courses on line, they are in effect creating a largedistributed database of course materials, organized in an ad hoc manner, with varying degreesof incompleteness. These materials can potentially be shared to provide an educationalexperience far richer than any instructor could

More sophisticated programs (Java, JavaScript, or a plug-in) allow for a constant connection between users and the automation program. However, theseprograms tend to be more difficult to implement. Since WWW users are accustomed to delays inweb responses, we used the simpler LabVIEW CGIs.One of our initial programming objectives was nearly simultaneous use of the site by multipleusers.

Students report that mathbecomes more difficult, that they receive less support from parents, teachers and peers forstudying math, and that math becomes more anxiety provoking over time. Female studentsreported that math was more difficult than did male students, and females rated themselves asmore anxious in quantitative situations than males, even though their mathematical ability wasapproximately equal [2]. In fact, as early as the seventh grade, boys plan to study more maththan girls do [3]. High school girls perceive math to be less useful than boys do [4], and valuemath less than boys do [5].

by the problem-solving sessions. The feedback cycle forhomework and exams is often very long; it can be days, weeks, or even months, before a crucialmisconception, possibly held by a majority of the class, is identified. In some cases, thesemisconceptions can even impact understanding of subsequent material. The immediate,supervised practice of skills to solve problems can quickly reveal gaps in understanding andallow other students to clear up misconceptions. Many traditional courses throughout theengineering curriculum can benefit from these small informal problem-solving sessions, relatedto what Smith describes as "Informal Cooperative Learning Groups"1.
