: Freshman/Sophomore Retention, 80%; Two Year Retention, 72%;and Six Year Graduation Rate, 46%. All of the university numbers have been fairly consistentover the years with a small upward trend. Direct comparison with numbers in the above tableshows that the department retention figures are comparable to those of the university, albeit withmore scatter due to the smaller sample sizes. However, the graduation rates are much better forthe department than for the university as a whole. Note that some figures are quoted as “greaterthan” since the requisite time period has not yet expired; those numbers reflect graduates thus far.The most recent freshman/sophomore retention figures in the table are a disappointment, as thatreflects the first class to

My child was encouraged to participate and it was OK if she couldn't work on a project."• "It exposes students to various aspects of engineering, team building and socialization. Students make friends from other schools."• "My son enjoyed it a lot."Program Leader Reflection: The program is a highly satisfying outreach to the community.Each leader can recall numerous examples of unsolicited parent feedback thanking RHIT andEXPLORE

These modifications would include:additional lectures by the instructor, reduction of the number of student presentations, instructorinput prior to student presentations, an earlier start on the design project and a more structuredenvironment for learning how to use H2 ONET. Both the students and the instructor appreciatedthe practitioners’ presentations and the assistance they provided for the design project.

daunting set of conditions would have to be met. Specifically, - proper course objectives that arise exclusively from the educational objectives and fully encompass all of these objectives must be set - tests and other graded assignments must completely capture these objectives - student performance on exams or assignments must be a direct reflection of their abilities and not be influenced by test anxiety, poor test taking skills, etc.There should be a direct correlation between student performance in courses and the overalllearning of the students only if all of these conditions are met every time.

) role modeling experiences, it is also quite possiblethat these findings do reflect actual advantages of the historically Black universityenvironment. Likewise, the growing availability of women’s support services (e.g.,Society of Women Engineers) and increasing numbers of female role models may havebeen responsible for our female participants’ expectations regarding social supports andbarriers. These possibilities notwithstanding, women and most racial/ethnic minoritygroups continue to be substantially underrepresented in science and engineering fields, andthe educational environment is often viewed as part of the problem14.

The neutronbeam is approximately 35 cm in diameter at the screen, resulting in a radiographic L/D of 140.The object turntable is approximately 10 cm in front of the scintillator screen. The photonsgenerated in the screen are reflected from the mirror and then pass through a 50 mm lens into theCCD camera. The CCD camera consists of a rectangular array of 1024 x 1024 pixels (24 •m x24 •m). The image data are collected in a 16-bit format.

specialty based on a study by theNational University Continuing Education Association.2 According to a 1991 National ResearchCouncil study, university curricula, in general, did not reflect the modern design practices used inmost competitive companies.3 The reason behind this is that faculty teaching these courses arerarely aware of the most recent design techniques. Therefore, it becomes a mandate for thepracticing engineer as well as for the engineering technology educator to treat their careers asdynamic entities that require constant updating. So how can this be accomplished? There areseveral options faculty can pursue such as attending conferences and workshops, taking time toconduct research, taking a sabbatical, reading trade magazines, and
