the systematic pursuit of improvement in thequality of engineering education that satisfies the needs of constituencies in a dynamic andcompetitive environment. Although institutions may use different terminology, for purposes ofCriterion 3, program outcomes are statements that describe what students are expected to knowand be able to do by the time of graduation. These relate to the skills, knowledge, and behaviorsthat student acquire in their matriculation through the program. For the purpose of accreditation,engineering programs must demonstrate that their students attain:(a) an ability to apply knowledge of mathematics, science, and engineering;(b) an ability to design and conduct experiments, as well as to analyze and interpret data;(c

In the program the Euler angle pitch rate is integrated to getpitch angle. But students are introduced to the quaternion method used in full flight simulatorswhich avoids the singularity at 90 degrees of pitch. Please see Appendix A for an example of astudent written program. In contrast, the flight model in the EFS is “industrial strength”.2 Use of Engineering Flight SimulatorThe Parks College Engineering Flight Simulator is used in a variety of ways a) to give AE students some “flight” experience, albeit simulated flight b) to provide a platform on which AE

Most of thosestudents had also difficulties interpreting the error messages and debugging their code.Audience Analysis: Students Interest and DemographicsFor the first offering, the Fall 04 tutorials, the number of students in attendance had a peak at 45and decreased as the semester progressed. Not surprisingly, there was a clear peak inattendance at the tutorial and office hours when homework involving MATLAB was due in oneof their 'for credit' courses, such as Control Theory or Thermodynamics.

overthe course of the semester. Because the first project was guided and straightforward, whereas thesecond was industry-sponsored and much more open-ended, it was expected that tolerance forambiguity would have a greater impact on the variables measured for the second project. In otherwords, the personality trait of tolerance for ambiguity was proposed to be more relevant whenthe project demands involved a higher degree of uncertainty and abstractness. Specifically, thefollowing hypotheses were proposed:(1). Individuals with higher tolerance for ambiguity will report higher levels of: a. self-efficacy, b. collective efficacy, c. satisfaction with the team, and d. conflict resolution.(2).
