12535Portland State Biomedical Physics: Computed Tomography
http://www.compadre.org/psrc/items/detail.cfm?ID=13719
This laboratory exercise uses standard physics laboratory equipment to create an analogy to image formation in Computed Tomography. Objects are placed in an enclosure that is largely opaque in the visible spectrum but mostly transparent to the near infrared light. The enclosure is scanned with a photogate using a rotating platform and an image of the contents is formed. This experiment conveys how an image is formed during a CT scan and highlights the important physical and imaging concepts behind CT such as electromagnetic radiation, the interaction of light and matter, image artifacts, and windowing. Resources provided include learning goals, an assessment, software for creating images, and instructions for assembling the equipment.

http://www.compadre.org/psrc/items/detail.cfm?ID=13627
This paper traces the importance of pedagogical content knowledge in the digital age to prepare today students for the 21st century. It highlights the need for ICT-based pedagogical models that are grounded in both the learning theories of constructivism and connectivism. One such suitable ICT-based pedagogical model is the TSOI Hybrid Learning Model. By means of a physics blended learning exemplar based on the TSOI Hybrid Learning Model, this paper argues for the use of blended learning approach as the way forward for 21st century teaching.Education Practices/Instructional Material Designhttp://www.compadre.org/psrc/bulletinboard/Thread.cfm?ID=13627Tue, 14 Jul 2015 16:31:41 ESThttp://www.compadre.org/psrc/items/detail.cfm?ID=13627Stormtrooper Explosion

http://www.compadre.org/psrc/items/detail.cfm?ID=13615
This interactive video tutorial is an exploration of Newton's Second Law. The videos show a constant force exerted on carts of different mass. When the same force acts on a more massive cart, it accelerates less. This vignette walks the user through experiments to verify part of Newton's Second Law. With video analysis the user sees that the same force acting on twice the mass produces half the acceleration.

http://www.compadre.org/psrc/items/detail.cfm?ID=13230
Physics education literature recommends using multiple representations to help students understand concepts and solve problems. However, there is little research concerning why students use the representations and whether those who use them are more successful. This study addresses these questions using free-body diagrams (diagrammatic representations used in problems involving forces) as a type of representation. We conducted a two-year quantitative and qualitative study of studentsâ€™ use of free-body diagrams while solving physics problems. We found that when students are in a course that consistently emphasizes the use of free-body diagrams, the majority of them do use diagrams on their own to help solve exam problems even when they receive no credit for drawing the diagrams. We also found that students who draw diagrams correctly are significantly more successful in obtaining the right answer for the problem. Lastly, we interviewed students to uncover their reasons for using free-body diagrams. We found that high achieving students used the diagrams to help solve the problems and as a tool to evaluate their work while low achieving students only used representations as aids in the problem-solving process.Education Foundations/Problem Solving/Representational Usehttp://www.compadre.org/psrc/bulletinboard/Thread.cfm?ID=13230Tue, 23 Jun 2015 07:08:06 ESThttp://www.compadre.org/psrc/items/detail.cfm?ID=13230Paradigms in Physics: Interpreting Effective Potential Plots
