Session 13XX Challenge-Based Instruction in Biotransport Robert J. Roselli Department of Biomedical Engineering, Vanderbilt University, Nashville, TN 37235AbstractAn introductory physiological transport course was recently redesigned to take advantage of thebenefits of challenge-based instruction. In this mode of instruction a series of specific challengesare introduced throughout the semester. The challenges are based on real problems inbiotransport and are designed to motivate students to discover a solution. For example, principlesof
distribution of grades on these evaluation instruments to assess cadet attainment of eachcourse block objective.Step 3: Assessing the Level of Attainment The achieved grades (A, B, C, D, and F) on each evaluation instrument are plotted vs.number of cadets achieving these grades. A rubric defines the standards to assess theperformance of cadets on each evaluation instrument. The rubrics allow us to assess cadetperformance as: • suspicious (most frequent grades are A and B), • acceptable (most frequent grades are C or better, with less than 20% F’s), • marginally acceptable (most frequent grades are C or better, with more than 20% F’s), or • unacceptable (most frequent grade is D or F
the results of the discussion in two ways. First, as examples, we include images ofsome art works chosen by participants to represent their struggles and successes.Simultaneously, we provide descriptions – paraphrases or their own words – of why theseimages were chosen and what they represented to the women who chose them. These images arepresented within categories that were identified with a post-hoc inductive coding scheme basedon the participants’ descriptions of their rationales for choosing particular images, according toestablished qualitative research methods [18-20]. The major themes identified were: (A)balancing work, family and personal life, (B) internal career barriers, (C) external career barriers,(D) optimism about academia, (E

Connecting rod fracture due to axial loading.Holes act as stress risers due to a dramatic change in cross-sectional area (see Figure 4 for afailure example). In practical calculations, this is accounted for by evaluating the stressconcentration factor defined as: u maxK? u nomFor a bar in tension, u nom is the average stress based upon the net cross-sectional area. In theseparticular calculations, the maximum allowable stress u U is substituted for u max as the rod wastested to failure. The value of K can be found by applying the ratio of d / b in graphs found inStrength of Materials texts, for example Gere6 used in our course. Thus the

procure a suitable model. After extensivesearching for available models from various sources, a set of lines corresponding to a generichigh length-to-beam ratio (L/B) SES hull were provided by a local engineering consulting firm.From these lines, the USNA Model Shop constructed the model, using advanced composites toreduce the structural weight without sacrificing rigidity. The final product was a model with alength of 7.8 ft (2.4 m), resulting in a 1/64 nominal scale SES, whose principal characteristics areshown in Table 1.

accompanied by loud heavy metalmusic which intensifies the shocking elements. The irony is that the fast-paced media (such asCNN) helped promote the phrase “Shock and Awe” during the 2003 Iraq War. Although itcannot be documented, one wonders if the U.S. Army’s enlistment increased from the media’suse of the phrase “Shock and Awe.”B. Successful Youth OrganizationsYoung people are drawn to adventure16, and adventure has been defined as a dangerous, exciting,or perhaps shocking experience17. (This helps explain the popularity of fireworks amongteenagers.) Imagine watching a 12 years old grab an axe and proceed to sharpen it. Next theyouth begins chopping at some logs. Then he/she starts tossing the logs into a bonfire that isblazing next to him/her

Torque is applied to the free end of the cylindrical shaft using a ~six inch longloading lever arm from which is hung a cradle of deadweights. The angular displacement of theshaft in response to torsional loading is measured using protractors two protractors (marked indegrees) located at B and C along the length of the shaft to eliminate any rigid body motion atthe fixed end (A).

which the break occurs using a magnifying glass. What is demonstrated is plasticdeformation – a type of deformation in which the object undergoes a permanent shape change, orfracture, and evolution of energy is usually involved in the deformation. This test also illustratesthe mechanical property of ductility, in which a material is capable of undergoing plasticdeformation before fracture. In this case, the number of bends the metal paper clip can withstandbefore fracture is a comparable measure of ductility. The new employees must also address thefollowing question in their memorandum: b) What would be the case if the metal paper clips had no ductility?

Session 1163 Strategies for Creating Web-based Engineering Case Studies Donald R. Falkenburg, Diane Schuch Miller Wayne State UniversityAbstractLinking academic learning with real-world experiences motivates students and significantlyimpacts depth of learning. The Greenfield Coalition is developing and deploying case studies tosupport its programs in manufacturing engineering and technology. This paper describes theGreenfield case methodology, and presents a four-step design process used to author anengineering case.Integrating LearningMost engineering problems are not like the problems at
obstructions between the transmitter andthe receivers at each art object (Figure 1). The second room required a mirror placed along onewall as some art objects obstructed the laser beam's access to the receivers on another objects.Students were asked to apply their knowledge of basic high school level algebra andtrigonometry to answer a series of questions. With regards to the first room, the students wereasked:a. How can you consistently and quantitatively describe the location of the objects and the transmitter? That is, how can you use numbers to describe the exact location of the objects and the transmitter in the room?b. How will you consistently and quantitatively describe the position of the transmitter (and thus the trajectory of

We show that one particular assignment, the developmentof autonomous mobile robots, ties together interdisciplinary design, experiential learning,teamwork assessment and other topical educational subjects in powerful and unique ways. Weidentify best practices taken from our experiences, focusing on (a) undergraduate experiences infire-fighting robotics and in the AUVSI Intelligent Ground Vehicle Competition; (b) integratingrobotics into the first year engineering design courses, advanced research project teams, andsenior design projects; (c) robot design as a medium to promote teamwork; (d) methods ofevaluation and assessment of robotics curricula and
of the internet as acommunication infrastructure between the student and the equipment, which may be ingeographically different locations, and (b) the adaptation of these experiments to be remotelycontrolled. Several researchers in the area of control engineering have successfully developed remotelycontrolled experimental setups for both the in-class teaching and distance learning5-7. A web-based tutorial and tele-operation system for earthquake engineering education has beendeveloped at Southern Illinois University8. However, it did not address remote control. Once theinput values were set, remote viewing and analysis were the only objectives. Changes to theinputs were not needed. “The Web pages allowed students and interested engineers
