Very inexpensive and wide area solar cells may use amorphous silicon thinfilms which are easily deposited over a large area but do not provide very high efficiency2,3.Solar cells are similar to batteries in that they provide a voltage to a load; but whereas a batteryprovides a constant voltage, a photovoltaic cell provides a voltage and current which varies withthe load resistance itself4.

reflecting on the content of the course and the student comments, several modifications aresuggested for improving the effectiveness of the course. These modifications would include:additional lectures by the instructor, reduction of the number of student presentations, instructorinput prior to student presentations, an earlier start on the design project and a more structuredenvironment for learning how to use H2 ONET. Both the students and the instructor appreciatedthe practitioners’ presentations and the assistance they provided for the design project. Studentswere quite satisfied with their final results and report. However, there were some frustrations inlearning the program and implementing it. The students handled this in a professional

The ETKs will conform to astandard format, and undergo a uniform set of tests and evaluations. Our goal is todevelop, test, evaluate, and distribute six to ten distinct ETKs during the next three years.ETKs are being designed according to the best pedagogical principles [4,5]. They willinvolve active, cooperative learning. The students will work in teams to solve problemsand design products. The middle school students will reflect on what they have learned,and explore the impacts or consequences of technology. These materials will promotesocial, ethical, aesthetic, and environmental awareness. Finally

daunting set of conditions would have to be met. Specifically, - proper course objectives that arise exclusively from the educational objectives and fully encompass all of these objectives must be set - tests and other graded assignments must completely capture these objectives - student performance on exams or assignments must be a direct reflection of their abilities and not be influenced by test anxiety, poor test taking skills, etc.There should be a direct correlation between student performance in courses and the overalllearning of the students only if all of these conditions are met every time.

) role modeling experiences, it is also quite possiblethat these findings do reflect actual advantages of the historically Black universityenvironment. Likewise, the growing availability of women’s support services (e.g.,Society of Women Engineers) and increasing numbers of female role models may havebeen responsible for our female participants’ expectations regarding social supports andbarriers. These possibilities notwithstanding, women and most racial/ethnic minoritygroups continue to be substantially underrepresented in science and engineering fields, andthe educational environment is often viewed as part of the problem14.

Indeed, it seems that the number of students attracted to the ECEdiscipline by working on radios, automobiles, electronic kits, etc. before entering college issteadily decreasing. Now, many students

The neutronbeam is approximately 35 cm in diameter at the screen, resulting in a radiographic L/D of 140.The object turntable is approximately 10 cm in front of the scintillator screen. The photonsgenerated in the screen are reflected from the mirror and then pass through a 50 mm lens into theCCD camera. The CCD camera consists of a rectangular array of 1024 x 1024 pixels (24 •m x24 •m). The image data are collected in a 16-bit format.

specialty based on a study by theNational University Continuing Education Association.2 According to a 1991 National ResearchCouncil study, university curricula, in general, did not reflect the modern design practices used inmost competitive companies.3 The reason behind this is that faculty teaching these courses arerarely aware of the most recent design techniques. Therefore, it becomes a mandate for thepracticing engineer as well as for the engineering technology educator to treat their careers asdynamic entities that require constant updating. So how can this be accomplished? There areseveral options faculty can pursue such as attending conferences and workshops, taking time toconduct research, taking a sabbatical, reading trade magazines, and

In these trying financialtimes, most new faculty members perceive that hiring and tenure decisions are based on thepotential to develop an externally funded research program or a proven research record. Theinstitutional emphasis on research is reflected in a reward structure that values researchaccomplishments over teaching improvement. For new tenure-track faculty, the lack of externalmotivation for change in teaching methodology combined with the lack of formal training, leadsto a “trial by fire” indoctrination into teaching. As a result, most engineering educators tend toteach others as they were taught. Faculty simply emulate the professors that they remember fromtheir own schooling.To

specific costs for fatality and injury. These costs were developed byestablishing a value that consumers are “willing to pay” (WTP) to reduce the probability of fatalityor injury. Since this WTP cost reflects only the value that a group of individuals places onavoiding injury, the FAA method adds other direct costs to the WTP value such as legal andemergency medical expenditures to develop a total cost. For a fatality, the FAA identifies $2.7Mas the cost benchmark.The WTP values for injuries are based on evaluating the loss of quality or quantity of life incurredby the injury as a fraction of the fatality cost. For example, the WTP cost of a minor injury isevaluated as 0.2% of the loss of life cost and medical and legal costs are then added to
