Session 2663 Overcoming Barriers to Deliver a Quality Hands-on Mechanics of Materials Laboratory Course at a Distance David G. Alexander, Ronald E. Smelser University of IdahoAbstractTraditionally, hands on skills have been taught in a laboratory environment where students workin groups to investigate scientific principles. This learning environment is rich in discussion andparticipation that can actively engage the student in his or her learning. Simulating thislaboratory environment has been one of the biggest obstacles for distance education programs.The goal of this

Its meeting schedule is set for two two-hour sessions perweek. The class usually has a mixture of sophomores, juniors and seniors.The variation in the academic achievement between students and in the students’ backgroundmakes it difficult to use one method of delivery to achieve the learning objectives. Thus, varietyof teaching and learning strategies for the engineering mechanics class at the FAMU-FSUCollege of Engineering has been developed and used. These strategies include:1.

Analysis and Discussion of ResultsThe results from traditionally teaching Engineering Mechanics are compared to those from thetraditional teaching combined with the Internet teaching. Such comparison is based on the sameconditions, namely, using the same textbook and materials, the same number of assignments(e.g., ten homework and quizzes given weekly) as well as the same tests and exams materials(e.g., the same problems for two comprehensive tests plus the mid-term and final exams).

Selection - The results from the analysis stage are evaluated to determine how well thespecifications are met. Candidate solutions are compared. Usually the synthesis, analysis andevaluation sequence will require several iterations to achieve a satisfactory solution.6.

From there we discuss the concept ofair resistance and, using a fan with streamers attached, allow the children to discover theaerodynamic design of each ball. The final portion of the class examines projectilemotion. Using a hose, we use a stream of water to illustrate the path of a projectile. Wethen ask the children to guess which balls will make the best projectiles and how theymust be thrown. Through a series of experiments, the children then have an opportunityto test their hypotheses.The class is fun, familiar, and quite intuitive for children of each age with whom we haveworked.
