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

Angle of Twist for Round and Square Torsion Specimen For the round specimen, from any text on Mechanics of Materials, such as, Reference [3] Which gives G = 3.94 x 106 psi For the square cross section, the determination of torsional stiffness requires consideration of warping which is available only in advanced texts on Mechanics of Materials, such as, Reference [4]. Stiffness for the square specimen, (2) This gives α = 0.138 which compares favorably with the analytical value of 0.1406 [4] CONCLUSIONS Warping has been demonstrated using (a) twisting Styrofoam specimens, (b) Membrane Analogy, and (c) Torsion experiments involving shafts of circular and square sections

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. In this lab, as well as many other labs, students were required to fashion a hangersystem and determine a means to accurately determine

notice absences (without any formal attendance taking).4. 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. Life-long learning skills, the ability to

Next, we illustrate the development ofspecific relationships and attributes, and highlight the challenges of establishing a knowledgearchitecture for seemingly straight-forward concepts (such as coordinate systems and units). Nextwe show how the ontology can also be linked to specific curricula and in particular learningoutcomes associated with courses (as well as ABET) in which specific concepts are introduced.Finally, we explain and demonstrate the query procedures through which the ontology is minedfor relationship information that–despite their expertise–experts may not fully be aware of. Ourresults so far indicate that an ontology can indeed be

Although it may be arguedthat the inclusion of more learning outcomes may overburden the students and require them toallocate more time for this course, the feedback from students for the last two semesters has beengenerally positive. This paper provides the details of the curriculum and explains the rationalebehind the changes in a critical course for ME and CE students. It is expected that the curriculumwill lead to a broader discussion on the need to revamp critical courses in the engineeringcurriculum in order to enhance student engagement, and in an attempt to improve studentretention in engineering.Keywords: Curriculum, Statics, Dynamics, Scaffolding.1.
