Probst Department of Physics and Engineering Physics Southeast Missouri State University Cape Girardeau, MO 63701 AbstractMany concepts in physics and engineering courses cannot be understood easily. Althoughpowerful computers with advanced software can generate fancy animations, students still cannotgrasp these concepts without spending time reflecting on them. In the past, homework was thetool used by instructors to challenge students and enforce their learning. Unfortunately, nowmany students can bypass this challenge and directly go to the solution manual for answers,which is widely available from the

impacted research, but also the classes that are using Buddy.The items in Tables One and Two reflect considerable effort on the part of faculty, students, andthe co-authors of this paper. It should not appear as though these results were not “hard-won.” Inthe conclusions of this paper we list some of the issues that have arisen in this deployment andoperation of the Buddy cluster in hopes that others can at least be aware of pitfalls.Conclusions and DiscussionAt UCO an NSF MRI grant was competed for and won for a HPC cluster, Buddy, to enable andenhance the research computing environment at UCO, which had not had any such facilitiesbefore. The competition for Buddy took several tries with
activities to develop students’ reasoning skills and therefore, increase engineeringstudents’ physics learning.IntroductionScientific reasoning refers to “cognitive abilities such as critical thinking and reasoning” (Bao etal, 2009, p. 586) or “skills involved in inquiry, experimentation, evidence evaluation, andinference that are done in the service of conceptual change or scientific understanding”(Zimmerman, 2007). It is needed in problem solving situations and requires methods of scientificinquiry such as the cycle of analysis, testing, reflection and revision, in order to construct adeeper understanding of the situation. Scientific thinking is “purposeful thinking that has theobjective of enhancing the seeker’s knowledge” (Kuhn, 2010, p. 2).To
