Bruce Mason, University of Oklahoma Wolfgang Christian Davidson College Francisco Esquembre, University of Murcia, Spain Mario Belloni, Davidson College OSP is supported by NSF grant s DUE-0442581 and 0937836.

Contemporary Physics Education “A curriculum in which computation is absent or plays a minor role is inauthentic to the contemporary discipline. This absence is one of the most striking examples of our failure to update the curriculum.” B. Sherwood “Tripartite” Learning Platform Solution: • Open Source Physics (OSP) Java code library and tools. • Easy Java Simulations (EJS) simplified java modeling tool • ComPADRE NSDL pathway for Physics & Astronomy
Pedagogic Advantages of Modeling • Students are actively involved in the PHYSICS. • Modeling is exploratory, like labs. • Modeling engages students predicting phenomena. • Computer modeling allows exploration of complex problems, visualization, and communication. • Modern science involved experiment, theory, and modeling.
Modeling Examples • The Falling Slinky model.What happens to the bottom when it begins its fall? • The bottom end will move up initially. • The bottom end will move down initially. • The bottom end will remain at the same point for a short time before it begins to move. • The Falling Cup and Ball model. • The Colliding Galaxy model.
Ideal Solution The ideal solution would be to get a simulation that: Is ready to run (for a first impression) Is modular Does not require non-standard, heavy-weight software Can be inspected in an accessible way Can be downloaded and used locally Can be modified (and re-run) Can be localized (translated to your language) Has been peer-reviewed (quality control) Has been used by other teachers Is absolutely free Is intellectually traceable (Add your own requirement…)
The philosophy of Easy Java Simulations • Good educational software needs to be adoptable and adaptable. Edward Redish in the Foreword to “Physlets” Francisco Esquembre, University of Murcia http://www.um.es/fem/EjsWiki/ Power to the People!
Results • Teachers NOT Java programmers • Todd Timberlake (Davidson College, NC) • Phases of the moon • Phases of Venus • Anne J Cox (Eckerd College, FL) • Generator • Falling loop • Adoptable, Adaptable, and UNDERSTANDABLE • Download, Right Click, Go!
