scientific and engineering calculations. It iswidely used for normal applications and a large portion of the student population with PCs isfamiliar with its usual applications. However, many do not employ Excel (Excel-solver) packageto solve engineering problems. Therefore, using Excel for this purpose eliminates the need topurchase specialized software packages for various applications. The problem setup is effortlessand quick, and once formulated it can be used repeatedly. As a result, it is time and cost effective.A case study of solving linear homogeneous 2D steady state partial differential equations waspreviously reported 1.In this paper, a numerical solution of an unsteady state heat equation is presented. The heattransfer problem is solved

in Table 1. Thesettings were chosen so that the students would get immediate feedback on whether or not theirsolutions were correct (Show detailed results On), but yet not reveal the correct answer (Revealcorrect answer Off). The students were allowed to take the assessment multiple times (Allowmultiple attempts On). This encouraged the students to repeat the assessment until they receiveda good score. Two steps were taken to help ensure they did not simply memorize (or write down)the answers to specific questions. First, when possible, large problem sets were created for thequestion pools. The individual assessment problems were then drawn randomly from each pool.This helped ensure that different problems would be asked each time a student

collaboration problems have been the focus in thecreation of collaboration tools. Most CAD systems today either have a web basedcollaboration module or can facilitate collaboration from within the software [1][2].There are even systems that specialize in inter-application collaboration. Alibre Designmakes a CAD tool that allows engineers to collaborate using different CAD packages [3].In non engineer-to-engineer scenarios these tools suffer both from a technical perspectiveand from a usability perspective. This can be attributed to the fact that these tools havebeen adapted from engineering tools and do not focus on media presentation anddelivery.Most of these collaboration systems can be placed into one of two categories.

mentalrepresentations of concepts.The knowledge and skills already acquired by the learner play an important role when formingmental representations of new concepts. Rather than viewing the mind as a tabula rasa, a blanktablet upon which knowledge can be written, research on cognition supports the notion ofknowledge as an internal construct that cannot be transmitted directly. 1 Thus, instructors cannot“give” students knowledge directly. These notions form the basis of constructivism, the dominanttheory of learning in modern cognitive science, derived from Piage t’s work on childdevelopment. According to this theory, learners must actively incorporate new conceptualinformation into an existing set of beliefs.Furthermore, learning requires the learner’s

Coal fired power plants are now the largestsingle source of power supply for Los Angeles and other metropolitan areas in California. Naturalgas supplies about 20% of the City of Los Angeles’ energy demand, hydroelectricity accounts for12%, nuclear 9%, and the remainder comes from purchased power through wind, biomass, solar andcogeneration. Since June 2000, California’s electricity market has produced extremely high prices asa result of deregulation.
