for a more applicable early experience, an experimentalintegrated pre-engineering curriculum (IPEC) 8 was developed and implemented fall 1996 withsponsorship from the National Science Foundation. The fundamental goals of this project were asfollows:1. To improve the students’ depth of understanding of the mathematical models of the physical world;2. To deepen students’ understanding of the physical principles that are the foundation ofengineering problems;3. To increase students’ use of mathematical models in solving basic engineering problems;4. To increase students’ involvement and sense of belonging in and personal commitment to the Page

partnership is to attract and retain women, Hispanics, African Americans, and otherminorities individuals to engineering. Students participating in the program are exposed andtrained on NASA’s mission, given seminars on the realities of the workplace, diversity, andgender issues. Students attend to their regular curriculum during the academic year, whileworking on projects for NASA. This model is being tested at various levels to transfer it toindustry at large. Our preliminary results indicate that such partnership provides a win-win-winsituation for the student, industry, and faculty. This article discusses the partnership model andits implementation.1.

group design was used in the first study where both the control andexperimental groups completed the 30 items on the PSVT. After a short break period, bothgroups completed an equivalent form of the PSVT with coordinate axes added to the 30 items forthe experimental group. The following conclusions were drawn from the initial study:1. When examining differences between the experimental and control groups, the coordinate axes had only a small influence on scores. The mean score for the experimental group was greater than the mean score for the control group, but the difference was not significant.2. The coordinate axes had a significant affect on response times. Analyses of response times indicated that more time was required to process the

special for the year 2000, the rules were substantially changed for 1998. The site wasmoved to the Department of Energy’s Hammer facility. The Hammer facility is a hazardouswaste cleanup training ground, and mockups of disaster scenes are available, including a burningfuel truck, an overturned railcar, and a smoke-filled building. Because these props wereavailable and because the site is in a remote location, the competition field size was increased toabout 1 acre. The 1997 vehicle was only capable of about 10-15 minutes of flight time, which isnot enough to search the new larger field. To allow increased payload for more fuel andbatteries, the team moved to the Bergen vehicle instead. Many of the same electronics wereemployed with some upgrades

Once the reverse pushbutton is pressed, the command signal decreases until it is zero when the motor has stopped. Nowthe system will wait for one (1) second to insure that no current is passing through the coils. Sincethe frequency is 60 Hz, a one (1) second delay is a sufficient delay time. The controller will changethe phase sequence and automatically push the motor starter. The motor will have a reverseddirection of rotation.

First, providing awareness of practicallife of all kind of engineers and answering all puzzles in the students’ mind about engineering.Second, setting competencies that can help students to master problem solving as well as basic skillenrichment. Third, developing the course activities and materials that practice all competencies. Thisstrategy was the key to increased enrollment in engineering.
