The system requires that students include the reaction and then specify that it has zero magnitude.

Suggestions and conclusions are made at the end of this paper.Definitions of Computer Simulation and Computer AnimationAlthough computer animation and simulation have been used to help students visualize a varietyof phenomena, the terms of “computer simulation” and “computer animation” are not explicitlywell defined in most of the studies that are examined in this paper. Only a few studies includeddefinitions of these two terms. According to Larvive 16, “animation” is a form of cartoon used tohelp one visualize a difficult concept, in place of a description of the concept in words; and“simulation” is a program that accepts inputs, and simulates experimentations via

In the allowable stress experiment,students used a simple double lap connection (provided in the lab kits and shown in Figure 1)made of balsa wood to measure allowable shear stress. Students added an adhesive (such asdouble sided tape) to the Part B illustrated in Figure 1, and then suspended increasing weight toget to failure.

, the student co-authorsexplored early examples of Statics textbooks4, 5 that emphasized graphical analysis. Not only wasthe style of exposition distinctly different from today’s textbooks, but these texts effectivelyblended analytical and graphical techniques for solving engineering problems. Realizing that, inboth these cases, calculators were not available to students, professors or working engineers,served to emphasize the usefulness and power of the graphical techniques. These graphicalapproaches, while grounded in mathematics, had a great deal of embedded visual and physicalintuition.References[1] Baxter, S. C., & Johnson, A., & Fralick, B. S.

beams in mechanics of ma-terials. They include the following:1-11 (a) method of double integration (with or without the useof singularity functions), (b) method of superposition, (c) method using moment-area theorems,(d) method using Castigliano’s theorem, (e) conjugate beam method, and ( f ) method using gen-eral formulas. Naturally, there are advantages and disadvantages in using any of the above meth-ods. By and large, the method of double integration is a frequently used method in determiningslopes and deflections, as well as statically indeterminate reactions at supports, of beams. With-out use of singularity functions, the method of double integration has an advantage of needing aprerequisite in mathematics only up to simple calculus

Group BIn the Fall 2012 semester of Engineering Statics several teaching methodologies andprograms were used to help students in Group B understand and embody the type oflogical thinking, analysis, and self-learning that is required in the field of engineering.Student growth and confidence, during this course in particular, often is the factor thatdetermines if a student will be successful in engineering and if they will continue inengineering. The goals of the course in this area are that after taking this course thestudents would develop:i. Self-confidence in their ability to solve problems and more natural problem-solving skills,ii.

Some teaching strategies to overcome thisinclude computer simulations and the use of videos, but only a few researchers have utilizedmotion analysis systems or other instrumentation in their dynamics courses.One of the goals of our recent Keck Foundation grant is to incorporate our motion analysissystem into courses in engineering and kinesiology. To date, we have utilized three differentassignment versions in our dynamics course: (a) allowing students to select their own artefact foranalysis, (b) supplying six specific artefacts for analysis, and (c) interfacing with a Kinesiologyclass on motor learning to provide “expert” engineering advice on performance measures ofnovice jugglers versus advanced jugglers.We
