It is important that engineering students learnthe detrimental effects of stress raisers such as notches, holes, and sharp corners in machinemembers. Such discontinuities can cause a large rise in stress above the nominal value. Thistopic is introduced in the strength of materials course in the design of a stepped shaft withkeyways subjected to bending, torsion, as well as axial loads. The nominal axial stress, thebending stress, and the shear stress due to torsion in the shaft are each multiplied by thecorresponding

Several computer tools have been developed to maintain student involvement inengineering mechanics, combining lab activities with CSA in an authentic project15, 28, 29, 30. Themain educational advantage of using computer-based labs is the real-time display ofexperimental results and graphs, facilitating a direct connection between the real experiment and Page 26.221.5the abstract representation19. Nevertheless, acquisition of laboratory skills is often a learning goalin itself which cannot be completely replaced by simulations.It is a common pedagogical practice to use analogies. In
effort in recent years focused on implementing newtechniques to the teaching of engineering mechanics. This work has included combiningtraditional statics topics in a heavily design oriented backdrop (Russell 7, Condoor 8, Klosky etal. 9), focusing on application to real artifacts (Seif and Dollar 10), and combining statics conceptswith those from mechanics of solids and machine design (Chaphalkar 11). Recent effortsdocument successes with utilizing an inverted classroom (Papadopoulos et al.12) and otherinnovative pedagogies. The goal of improving educational outcomes via a highly interactiveclassroom has been shown to be successful in formats where lectures and laboratories arecombined and problem-based active learning techniques are

These hands-on laboratories canbe much more powerful than demonstrations and lecturing – the students can actually feel thegyroscopic moments generated. These demonstrations were assessed through two problems onthe final examination. The first asked what happens to the motion of a gyroscope when you pushgently on the outer gimble. The second involved the action-reaction moments involved withgyroscopic motion (e.g., if you are riding your bike and lean to the left, which way to do youhave to push on your handlebars).

tofeel where the tension was”. “I learned how to apply it to real life rather than memorizing it for anexam”.Introduction and BackgroundConventional engineering lectures are structured to present students with theory pertaining to aspecific scientific principle, followed by examples and practice problems. Once the students arepresented with the theory, their knowledge is usually reinforced with a laboratory experiment onthe material. This approach focuses on having students remember information for laterapplication. The issue with this approach is that students begin to think in terms of set test cases.If they are presented with a problem, they attempt to relate it to an example they have seen beforeand approach the solution in the same manner

However, in this first course offering, no separateaccommodations were requested.Discussion labs are where the online course and on-campus course differ in that the onlinecourse did not have a discussion lab. The discussion lab is a time when students in smallergroups of 24 students review additional example problems, take check-point quizzes, andparticipate in hands-on laboratory experiments with the teaching assistants. The decision not tohave a discussion lab for the online course was one that was made with much reservation. Thedriving factor was the dilemma of how to schedule a time when all 39 students would be able toCourse Format On-campus Statics
engineering courses could provide an authentic laboratory experience that helpsimprove students’ conceptual understanding of engineering mechanics concepts. Moreover,physical manipulatives are easy to implement, easy to duplicate and distribute,13 and can beextended to include different engineering subjects.Other studies have investigated the use of physical manipulatives in a variety of STEM areas. Theuse of hands-on (physical) manipulatives has helped engineering students in modeling andengineering problem solving.7 For instance, Coller indicated that the manipulatives helpedstudents increase their understanding of engineering concepts when they used manipulatives andwere able to see and feel reactions created by the manipulative.7 Another study

better engineering education overlap withstrategies that have been shown to be particularly effective for the recruitment, success, andretention of women and minorities12. Of particular importance is offering students extendedexperience in experimentation, observation, and holistic problem-solving, throughinteractive methods. Engineering is an intrinsically “hands-on profession,” historically learnedby apprenticeship, but increasingly distanced from laboratory experiences 13. With previousgenerations of engineering students, it was common for extended experience opportunities tooccur prior to entering university. Backyard explorations and repair of the family car,disassembly and reassembly of common household devices or machines often served as

A frame-by-frame study of the pictures of bouncing tennis balls obtainedusing high-speed cameras (2000 frames per second) in our laboratory demonstrated that thisprocess consists of four separate and distinct phases: initial contact, deformation of the originalshape, restitution and recovery of the shape of the ball, and separation and takeoff [6].

surprising that the retention rate of undergraduateengineering programs can be adversely affected. As a result, a Statics instructor may facesubstantial pressure (whether real or perceived) to minimize the attrition rate yet still preparestudents for subsequent higher-level engineering coursework.Various pedagogical approaches to teaching mechanics have been attempted with the intent ofimproving student success. Some approaches include supplemental instruction [2], interactivetutoring [3], recitations [4], virtual laboratories [5], online courseware [6], and gaming [7]. It isimportant to concede that even the most well-intentioned and passionate instructors may nothave access to the resources to implement these unique approaches. Thus, traditional
