consulted to help shape the new plan of study.For many years, the Purdue EET program prided itself as being one of only a few in the UnitedStates with a strong electric power program. The plan of study included a required electricmotors course, which was organized in a traditional pattern of magnetics, DC machines,transformers, and AC machines. Electives included a course oriented toward electric utilityoperations (generation and transmission), an electrical distribution course, 1 and two controlscourses. Despite this history, some faculty viewed the required course as a target for elimination,which would allow other topics to be included. Surprisingly, however, there were a few non-power faculty who felt the course should be kept exactly as it

modularizedcurriculum model in Mechanics designed to serve the needs of students pursuing degreesof Bachelors of Manufacturing Engineering (BME) and Bachelor of Science EngineeringTechnology (BSET) in Manufacturing. The curriculum provides a unified learningexperience including topics in mechanical physics, statics and dynamics rather than thetraditional distinct courses in these subjects. All learning experiences are rooted first inpractical applications with which the students are familiar and focus on instilling anintuitive understanding of key concepts prior to the introduction of formal analyticaltechniques. The complete curriculum is being implemented in computer-basedmultimedia form, allowing for individualized self-paced learning.1. Introduction

The combining of these with other learningresources such as mathematical packages and laboratory work is considered.1. IntroductionThere would appear, from recent reviews of engineering education in the USA1 and inAustralia2 that there is strong impetus towards a broadening of engineering courses and astriving to make students more central in the whole educational process. Coupled with thesedirections is a highlighting of longlife learning aspects so that students progressively takegreater control of their learning. This means that as important as the technical skills is theobtaining of the learning skills to ensure

3.214.1DiscussionSteady State AC Analysis - SophomoresCharles Steinmetz, in the late nineteenth century, developed a method for the steady stateanalysis of electric circuits that are excited by sinusoidal signalsi. Sophomore EE/EETstudents recognize this as the complex impedance approach to AC circuit analysis.Presentation of this technique frequently begins with the assertion that the forcedresponse of a linear time invariant (LTI) system will often be of the same form as theforcing function (e.g., a sinusoidal input yields a sinusoidal output of the same frequency,with, perhaps, a phase shift). A more detailed examination exposes that the mathematicalorigin of this assertion is the fact that: (1) the response of a LTI system to the complexexponential, ejωt, is

Physical distance among classrooms has no bearing on the dynamics of classroom or learning. There are advantages of classrooms being near each other. However, quality of sound is very important when all members of the class can hear anyone for greater interaction among students and the instructor to reduce the impact of physical distance. 2. Voice contact is comparatively more important than the small faces appearing on visual images on the screen. 3. More preparation required for the classes.

L is assumed very large, so that output current can be considered having no ripple at all. The diodes used are ideal diodes with zero switching delay. Hence, the shape of the output current is rectangular. But, this causes electromagnetic interference.
