. Most 50-minutelecture periods involve a set of PowerPoint lecture slides that run on average about 15 minutes,and then the instructor solves two or three example problems for the remainder of the period.Additionally, many classes use models and physical demonstrations to aid students in visualizingconcepts. These demonstrations are usually five minutes or less in duration. Students areassigned simple homework problems that are similar to the in-class examples, and theseproblems are turned in by the students at the beginning of the next class period for credit.Quizzes are given weekly to gauge learning and reinforce the most important learning outcomes.Upon grading of the quizzes the instructors note and record the specific mistake(s) made by
, mesh, and solve. Within about an hour, anyone who is familiar withMicrosoft Windows and understands the component description of a force can learn how to dothis for a diverse range of shapes and loadings. And the graphical portrayal of input and outputquantities makes it easy to detect many user errors. But what are educators doing to incorporatethis ubiquitous, increasingly inexpensive tool into basic engineering classes?The practice of embedding or integrating FEA into freshman design courses seems to have madean appearance in the 1990‟s, coincident with the movement to develop integrated freshmancurricula that include or emphasize design. Barr et al. (1998; 2005)1,2 describe their work toinclude FEA as part of a larger focus on solid

academicyear.Conclusion:A low-cost, compact, and portable experimental kit for online engineering statics courses hasbeen developed. The kit will bolster student proclivity with introductory lab equipment, which isa viable and effective way of rising student outcomes in mechanical engineering. Next, the kitwill be distributed to students and its efficacy on student outcome attainment will be assessed.References:[1] B.

With the leaky connections, theerrant dynamic pressure and velocity measured about 6 mm of water and 10 m/s, respectively.Thus, their digital measurement device appeared in every way to be working properly, but if thestudents took the effort to convert their pressure measurement to a velocity measurement, theymay realize that the velocity they were measuring was too low, which admittedly may requiresome amount of intuition that the students probably do not yet have.Because the exercise involves questions of accuracy, the students were also asked to assess theuncertainty in their measurements.

author failed to state it, deepened their conceptual understanding. In terms of Brown, et. al.’s[5] distinction between rule learners and example learners, these students appeared to be examplelearners relative to example problems, but rule learners with other activities.Learning problem solution strategies and not basic concepts from example problems is notsurprising at all. Example problems are placed in textbooks with the intent of teaching solutionstrategies. However, some students focus primarily on the example problems as an instrumentalmeans of doing homework problems. This practice, of course, places the student’s learning ofconcepts at a disadvantage.Changing study habitsAt the end of the semester the students completed a final journal
