He obtained the B. S. E. degree in biomedical engineering from Duke University, the M. S. degree in bioengineering from Clemson University, the Ph.

15.680.7Figure 4 shows that there was a slight increase in the scores on the spectroscopy question in Fall2009. However, it is hard to tell what is occurring, since the scores vary so much from year toyear. For this reason, we “normalized” the scores by dividing the score from the spectroscopyquestion by the score from the calculation question (Table 1). If, for example, class A did poorlyon both questions (i.e. 10 on both, out of 25) and class B did well on both (20), we may unfairlysay that class B was the better class and the teaching practices implemented within that classwere more desirable and well suited to the students. By normalizing, we would see that class Aand B were equal (1) and no conclusions about who had the better teaching practices
construct. The concentration of the purified constructwas determined by UV-VIS spectroscopy. The absorbance of theconstruct was obtained at 519 nm and the concentration wascalculated by the students using Beer’s Law (A=bc). In thisequation, A is absorbance, is molar absorptivity, b is pathlength andc is concentration. The molar absorptivity of 585nm QDs is 450,000L mol-1 cm-1.The concentration of the QD construct is important because whenrunning a gel electrophoresis all concentrations of the samples need tobe approximately the same. Otherwise, saturation of the sample willoccur, which makes discerning the individual bands on the geldifficult for the students. The conjugation was confirmed by gelelectrophoresis (Figure 3).

One advantage of using the hearing application for a lab project isthat it motivates further study of advanced digital signal processing courses where labs related tospeech processing and the auditory system are enthusiastically pursued by the students. a) b) Figure 2: a) A cochlear implant signal processor serves to separate the sound content in an acoustic signal into distinct frequency bands. Similar to chiming the keys on a xylophone, a cochlear implant activates distinct frequencies in the cochlea through electrical stimulation of auditory nerve

majority of students received final grades of an A+ to an A- (Figure 10). Of the studentsreceiving B grades, 66% worked on teams of 2 or more and these students usually had at leastone teammate who received a higher grade. This variability of grading within a team reflects theefforts of the instructors and advisors to assign grades as fairly as possible, using advisor andpeer feedback to help assess individual contributions to the Capstone project. Of the studentsreceiving C grades, 60% worked as individuals. In addition, their advisors were single-affiliationadvisors, mostly from BME (60%) and some from nursing (20%). This supports the findingsfrom the previous section in which combination advisors were found to generate the mostsuccess outcomes

This gives the students an understanding of the trade-offs involved when designing a component for “printing” using a rapid prototyping device. It also provides students with experience in using rapid prototyping, a tool that they will use in subsequent classes, and likely in their future careers. B.

The course grading was designed to be highly dependent on individual work submitted(70%) where as the rest 30% was based on the team submitted material (which included theposter and oral presentation). Although the laboratories were conducted in teams, each studentsubmitted their own abstract for grading. The use of abstracts facilitated this grading formatbecause each student could reasonably produce a 1 page report each week, without dependenceon others in the team. The classical laboratory format of having a team submit a multi-pagereport is often criticized by students who cite

Intensive Immersive Research Experiences for Undergraduates and Teachers: Undertaking Creativity and Innovation, Diversity of Thinking, and EntrepreneurshipAbstractOne objective of National Science Foundation efforts is the training of the future work force inscientific and technical fields. In summer 2009 research experiences for undergraduates (REUs)and teachers (RETs) were developed and implemented introducing participants to leading edgeresearch currently underway. These experiences were intended in part to fulfill the mission tocreate a diverse pipeline of future practitioners and educators in the Biomaterials field.The Research experiences for undergraduates and teachers were six weeks in duration and
University(BE@SLU) is to provide early undergraduate students (students entering their first or secondyears) with real examples of bioengineering career options (both research and industry) tosustain their interest in engineering through their early curricula. By exposing students to abioengineering research experience after their freshman year, the students may be better able torecognize their academic interests and may have a better idea of their career options inengineering. The program is structured to accommodate these early career students, with peermentoring, career discussions, and research training embedded into the program. The first weekof the program, “Training Week” not only covers basic laboratory technique, but we also have ajournal
