problems. This goal is reflected in theevaluation of the student questions as described in the next subsection.Methods – Assessing Student Submissions In both courses, the faculty agreed to evaluate student submissions on a four point scale.The low end of the scale, 1&2, were considered to be relatively simple questions. These werequestions directly related to the course material that could typically be answered by review ofthe course text or notes. Questions at the upper end of the scale, 3&4, were questions thatdemonstrated understanding of the course material and expressed interest in additional, relatedinformation that was not expressed in the course text or notes. The four point scale allowed the submissions to be looked at from

p. 3particular project has some impact on the outcome. Because students were designing anexperiment, the questions asked were, by nature, somewhat biased toward the “test andexperiment” category and the “learning” category as students had to reflect on how otherstudents would best learn a concept through the experiment developed. A second challenge is the question of how to normalize the results so that they can becompared to similar efforts in other courses and related to overall program effectiveness. Onepossibility of how this might be done is shown in Table 2. For the particular course underconsideration, the course goals are consistent with the idea that students should divide theirtime equally between technical and

The percentage ofwomen varies considerably by school/college ranging from 13.5% in Engineering &Applied Science to 90.1% in Nursing. 2UWM serves a racially diverse population consisting 15.8% while Milwaukee Countydemographics from the U.

of precession. When absorption occurs, a dip is noted in the spectrum, and conversely,when dispersion occurs (reflection of microwave energy), there is a rise in the spectrum (Fig. 2).These reflections, due to the absorption or dispersion of energy, are part of the EPR spectrum;which give the scientist insight into the sample’s molecular structure and behavior.The pulse EPR methodology allows a very short burst of microwave energy to the cavity’ssample (Fig. 3). The power level, duration, and repetition rate of these bursts are determined bythe experimenter, based on the sample’s properties and the kind of EPR information desired.For example, a long pulse width will fully irradiate the sample and cause all of the moments ofthe sample’s

credentials, reflecting that they meet the minimumproficiency levels that satisfy rapidly shifting manufacturing and employmentneeds.About 4000 workers from 700 companies, 300 subject matter experts and 30support organizations worked diligently to develop MSSC production worker skillsstandards. Subsequently, a team from the National Occupational CompetencyTesting Institute (NOCTI) and Raytheon assembled a validated, onlineassessment protocol. It is a multiple-choice test, combined with a computer-simulated exercise, comprised of four modules that in aggregate set theminimum requirement for a worker to gain certification. The four areas ofconcentration (modules) are safety, quality, manufacturing process andmaintenance.The Skill Standards

aspects of good requirements, which are exercised throughout the class.Completeness of requirements presents special challenge to experienced professionals, so it is notnecessarily a poor outcome that students are more tentative in their self-evaluation of this area. Itis interesting that the smallest bias of self-success over course aid occurred for objective 6 (0.16),while the largest occurred for objective 8 (0.63). This may reflect the students’ confidence inpresenting technical material from several previous courses.7.

specified as driving dimensions, so thatthey do not define the position of the linkage, but simply reflect the values of these dimensionsas link 2 is dragged to a new position. In addition to determining the values of the limitingpositions, the students can see that these positions exist when links 2 and 3 are collinear. Figure 4 Finding Limiting Position of Link 4 Figure 5 Linkage with θ2 DefinedThe last part of the problem is solved by changing the dimension defining θ2 to a drivingdimension, as shown in Figure 5. Although the linkage is now fully defined, any of the drivingdimensions (any of the lengths or the angle θ2) may be changed by double-clicking its value andentering a new value. For example
