possible, or should it benecessary, for traditional engineering education systems to fundamentally change to meetcorporate requirements? These are but a few of the compelling issues discussed in this paper.1. Situational BackgroundDuring the summer of 1999, eleven individuals representing a variety of engineering disciplinesand universities spent eight weeks at the Boeing Company as A.D Welliver Faculty Fellows. Theprimary objective of the Boeing sponsored A.D. Welliver Faculty Fellowship program is to"influence the content of engineering education in ways that will better prepare tomorrow'sgraduates for the practice of engineering in a world-class industrial environment." Now in its fifthyear of existence, the Boeing faculty fellowship program

on these characteristics educators have created instructionalmaterial using LabVIEW with success 4,5.Due to LabVIEW’s use for data acquisition and instrument control, it includes a number ofcontrols and indicators which can be placed on the front panel, LabVIEW’s version of agraphical user interface (GUI). These panel items are designed to duplicate the look andfunction of common controls and indicators found on equipment and instruments (Fig. 1).They include such common items as knobs, dials, meters, slide levers, switches, levelindicators, and charts. These items can be modified in appearance to almost anything desired.Based on these basic items more complicated interface items can also be constructed. Figure 1: Typical

Two JAVA applets have beendeveloped that provide an interactive, web based approach to the evaluation of thermodynamicproperties for steam and ideal gases.This paper continues with a brief description of the software development. This is followed by adescription and demonstration of the JAVA applets. Finally, conclusions are providedconcerning this work.II. Code DevelopmentIn developing these applets several different JAVA compilers were considered. BorlandJBuilder was chosen to be used for this purpose. One of JBuilder’s strengths was its drag anddrop feature for building the graphical user interface. As shown in Table 1, two other JAVAcompilers were given serious

class room education.Traditional classrooms have the advantage of creating an appropriate learningenvironment, and having an active (face-to-face) interaction between students andinstructors. Some of the limitations in this process are, (1) difficulty in providing courseinformation or handouts to every student including those who were absent; (2) inability tohave office hours that is compatible with the schedule of every student, (3) difficulty inadministering many quizzes and tests without increasing the workload of grading, and (4)complexity in obtaining a statistical assessment of class performance. Web-basedinstruction can be used to eliminate or minimize these limitations 3,4.The success of Web-based instruction depends on the ability and

problem-solving methods. This paper describes an ongoing process of course andcurricular review that has resulted in the development of a web-based learning environment (theInteractive Problem Solver) to supplement traditional instructional methods in an undergraduateDynamics course. The Interactive Problem Solver, which is still under development, is beingdesigned 1) to help students learn (and practice) rigorous problem solving skills, 2) to helpstudents develop an ability to understand and evaluate mathematical models and results in thecontext of physical reality, and 3) to provide a forum for instructors to evaluate the impact ofvarious features of a learning environment on student learning of tasks (problem solving skills)and concepts.I

available convertertopologies is not always easy to grasp from a textbook. Practical converters contain non-idealcharacteristics, filters, voltage or current limiters, etc. Often, it becomes difficult to see thedifferences among converters without the aid of computer simulations. The rationale ofproducing this website is to give students a more intuitive approach whereby they can learn thematerial by interacting with a computer. All major types of converters are dealt with as well asspecific topics such as electromagnetic interference (EMI), heatsink specifications, snubbers, andmagnetics. Performance characteristics such as converter efficiency, ripple, and total harmonicdistortion (THD) are also discussed.1. Introduction Power electronics

Third studentmodified the instrumentation during the spring semester of 1997. Since data acquisition byLabTech/CONTROL was not fast, we used ASYST[2] software for data acquisition, analysis anddisplay. During the Spring semester of 1998, fourth student worked on the project toremanufacture the shaft and the wheel anchoring system to closer tolerances to improve theaccuracy of measurements.The purpose of this paper is to describe the wheel-balancing machine and convey the experienceswe had during the design and construction of the wheel-balancing machine.MECHANICAL DESIGN OF THE WHEEL

.1. IntroductionThe Fundamentals of Mechanics course (Fall Semester 1999) at the United States Air ForceAcademy was used as a testing ground for introducing and assessing the effectiveness of visuallearning aids. The course combines statics and strength of materials at an introductory level forall students regardless of major (this will turn out to be a very significant point that must bekept in mind). Typically, the concepts of stress in objects caused by torsion, bending, andcombined loading are among the most difficult for students to grasp. For these topics, “enhancedlearning modules” were developed to bring visualization learning aids into the classroomexperience.The initial study4 (Fall 1998) attempted to correlate the effects of these

techniques in an engineering decision-making context.Engineering Economy textbooks typically use a mix of financial and engineering problems tohelp the students learn the basics of engineering economy. Financial examples, such as bankaccount savings, loans and bonds, are useful because they can be used to present time value ofmoney concepts in a simplistic form. Problems using an engineering decision making context inreal life tend to be more complex.Arguments can be made that courses in Engineering Economy should provide more of anengineering decision-making focus than is currently emphasized in textbooks. In recent yearsseveral papers in the Engineering Economy Division at the ASEE National Conference havesupported this view. Hartman[1] strongly

students lack essential connections between scientific/technologicaldescriptions and physical behavior of real systems. We believe that a successful first course inengineering thermodynamics must address these issues by careful and comprehensive pedagogyand assessment. This paper describes our approach that involves laboratory workshops.In our course is taken principally by mechanical and chemical engineering majors. For it, wehave developed nearly a dozen 1-hour laboratory sessions to augment classroom activities and tofacilitate student growth in connecting descriptions to behavior. These include 1) simple customdevices such as piston/cylinder systems and instrumented spray bottles of refrigerant, 2)"familiar" household devices such as bicycle

their approach will be described as an example of rational engineering design.Two memorable unsuccessful attempts by others will be described briefly before examining theWright approach. In these cases, the lack of success can be attributed to failure of the use of arational design process.The first example is an aircraft builtby Maxim (1894 - five years beforethe Wrights started their design pro-cess). He gathered pertinent informa-tion, but failed in the conceptualiza-tion phase: Instead of testing parts ofhis design in stages, he spent a greatdeal of money to immediately buildhis final aircraft (Fig. 1). It weighed Fig. 1. The first powered aircraft, built by Maxim in 1894 wasfour tons, was powered by

In this paper, a summary of the curriculumdevised for this writing technique will be presented. Writing topics selected and presented bystudent participants will also be shared. In addition, links will be made to the importance ofmaking science and engineering topics accessible to non-majors through the active process ofwriting.I.
