thesolar panel. Due to the production processes currently used, solar cells often show local defectsthat may affect their life time and efficiency. For this reason, there is a growing interest in solarcell quality control processes. Effective tools and methods are needed designed to assess andmeasure the quality of solar cells, especially in line during manufacture5-8.Finished solar cells undergo a variety of tests before they are assembled into modules. It iscrucial that low-performing cells are not incorporated into modules. Conventional quality controlmethods test the current, voltage, and resistance of each of the cells to determine whether it fallsshort of the required standards. The approaches for measuring solar cell current usually

This paper describesthe overall structure of the capstone course and projects, outlines the role and expectations forfaculty mentors, and provides an assessment of the impact and effectiveness of the facultymentoring on student performance and project outcomes.

The content of a node issimilar to the description of a topic within a course but at a more detailed level; it is presented inbehavioral terms.

First, theevaluation questionnaires provide the NCTT with a basis for establishing a primary thrust in thecurriculum and preferred skills set for a viable workforce. Second, the industry has evaluated theoutput of the program by means of internships, for both teacher and student. This activefeedback helps the faculty and partner school participants to redesign, revise, enhance, andinnovate according to industrial perceptions.The close relationship of the Massachusetts Telecom Council with NCTT allows for the Centerto obtain rapid assessment of the programs by over 300 companies in the telecommunicationsindustry.

This paperis based on preliminary results of a study being conducted by a team of researchers toinvestigate engineering students’ perceptions about what is cheating, how often they do itand how it can be prevented. It is the author’s personal belief that students do notinherently want to cheat for malicious reasons, but instead do so as a result of variousdemographic, situational and/or psychological factors. Therefore, a set of useabletechniques should exist that can counteract these factors and help students avoid thetemptation to cheat.II.

Copyright ©2001, American Society for Engineering Education The purpose of this senior design project is to use today’s engineering knowledge to analyze Peale’s and Paine’s designs. Based upon its assessment, the team will produce its own design for an 18th century bridge across the Schuylkill using the approach of either Peale or Paine. Finally a scale model will be built and tested to a design load deemed reasonable for 18th century use.Here the students were confronted with a significant societal problem that was amenable to atechnical solution. For the city of Philadelphia to grow, a means to span the Schuylkill River wasneeded. The gap at High Street was 390 feet wide. Two "new" design concepts had emergedduring the 1700’s from the

Thelaboratory took place in four major segments. In each segment, the students monitored thesystem, assessed its stability, and took corrective actions based on their assessment. The fourstages were: 1. Develop a stable, open system. In this stage, the students learned about the needs of the crayfish, set up their tanks, developed proficiency with the water quality tests, and allowed the tanks to stabilize. During this period, the students became aware of the complexity of their challenge. As the self-organization proceeds

In their report, the students are asked to compare thedifferent techniques to each other and to the accepted value, using appropriate statistics, andmake a judgment as to which technique should be preferred.
