model rocket manufactured by QuestAerospacet5. A diagram of the rocket is shown in Appendix A at the end of this paper. Thisrocket was chosen because of its unique payload section which is separate from the parachutestowing area. In model rocketry the parachute is deployed by the, “Ejection charge” that isproduced by the rocket engine after the thrust charge is depleted. The ejection charge effectivelyforces the rocket stages to separate and propels the parachute(s) out of the storage chamber. Byhaving a separate payload section, the sensors can be shielded from the violent pressure effectsof the ejection charge.The diameter and length of the combined payload and hollow nose cone sections placeconstraints on the physical design.

However, Mills and deAraujo (1999) determined that students’subjective perceptions of technologies used in teaching should not be ignored when comparingthe effectiveness of different technologies used in education.The research problem of this study was to determine whether there is a significant difference inthe effectiveness of anaglyphic and HMD-based stereo display methods in design and graphicseducation.

This paper presents the evidence that there is an overwhelming need for providinginternational experience for students in technical fields and evidence that American students arenot receiving such experience. The lack of student participation is especially prominent atCommunity Colleges or regional campuses, where large number of students tends to live at homeand commute to campus. The paper then presents several programs that have been attempted atvarious institutions and discuss their shortfalls. Finally the paper examines several programs thatoffer promise in providing such experience.The need for International Experience According to Byron Newberry, [1] and J. C. Swearengen, S. Barnes, S.

After revisions based on this round of testing, the game segments are testedfor instructional impact. This round of testing involves interviews, “think aloud”strategies, and pre/post surveys to test content knowledge.Motivation for the ProjectThe use of digital games has grown exponentially since the early 1980’s, when personalcomputers first appeared.

Putting this in the context of making design decisions,even though experience in the form of design knowledge may be accessible to an inexperienceddesigner, (s)he may feel compelled to select a concept to embody based on a subconscious desireto validate an initial ‘gut feeling.’ So, the challenge becomes finding innovative ways to guide anengineer toward the best solution(s) by building on existing design experience while simultane-ously discouraging tendencies to make choices or evaluations based on

In addition, students practice their timing technique and estimate theuncertainty of timing due to their response time using the stop watch. This is done using astopwatch to time ten second intervals displayed on an online timing device. With practice,students could typically measure within +/- 0.15 s of the “true” time. An insightful studentrecognizes that the timing device can give a misleading impression of accuracy -- limitations intiming technique introduce a significant uncertainty that exceeds both the published 0.01%accuracy of the device and the ILE of +/- 0.01 s.Students obtain the pulse rate first by measuring the time for

Dr. Lawson' s research centers on the nature and development of scientific reasoning patterns such as hypothetico-deductive, probabilistic, proportional, combinatorial, analogical and correlational reasoning. Major interests involve determination of factors that influence the development of these reasoning patterns during childhood and adolescence and determination of their relationship to each other and to scientific concept acquisition.
