Session 2368 Hands-on Learning in Engineering Mechanics using Layered Beam Design B. L. Newberry Oklahoma Christian UniversityI. IntroductionA sophomore level Engineering Mechanics project is presented that uses design and constructionto reinforce student learning of beam deflection and flexural shear strain. The project requires thestudent to design, to build, and to test a layered beam that minimizes cost yet provides specific in-plane and out-of-plane stiffness. Each student is presented with an inventory of available

comments from respondents are as follows: Positive Comments: • Yes, because it [engineering] was fun and very enjoyable. I learned things by being hands- on which is how I like to learn. • Engineering/technical was very interesting from the activities we got to participate in. I would like to challenge myself in getting to know engineering a little better. • Even though I attended a very interesting program, I found engineering was not for me. This is positive in my eyes because I found that something interesting like engineering is for a dedicated student in that field. I probably would not have been that dedicated b/c it did not interest me. P.S. - VT was my #2 choice! Go Hokies • Even though I've always been

In engineering practice,projects related to heritage resources are, in many instances, dealt with through the eye ofnew construction. Glimpses of hope for engineering heritage come, however, throughFederal programs like the National Register and the Historic American EngineeringRecord.Engineering education has a responsibility towards engineering and industrial heritage.This paper advocates introducing the heritage subject in engineering education. The paperwill address the following objectives: a) defining heritage and heritage preservationcontext; b) exploring the status of engineering heritage as an area of study in engineeringeducation, including efforts exerted by professional

Wehave found that students who typically fail to complete assignments are more likely to do so whenthey know that only selected problems will be graded.Another possible source for the occasional homework grade is to have each student come by youroffice for a few minutes during a given week to discuss their favorite and least favorite homeworkproblems with you. Make it very clear what type of discussion constitutes an A, B, C, D, or F. Inour opinion, the only way to make an F on this type of assignment would be to not show up!Basically, we would hope that each student would make an A or a B

Transfer is measured using the following scale from A to C: A is the root problem; B is if there are synonym replacement and changes in the data values; and C if there are changes in all three categories.Much additional work is needed to study these measures, but the initial scoring is designed tomatch the ordinal increase in transfer (or difficulty) as more elements of an exercise are changed.The following definitions of terms were used.
