This paper is the first part of a multiphase study examining students' mental models about the quantization of physical observables-light, energy, and angular momentum. Thirty-one second-year physics and physics education college students who were taking a modern physics course participated in the study. The qualitative analysis of data revealed six variations in students' mental models about the quantization of physical observables: scientific model, primitive scientific model, shredding model, alternating model, integrative model, and evolution model. These models were determined to be context dependent. In addition, some students are in a mixed-model state where they use multiple mental models in explaining a phenomenon and use these models inconsistently.

Identifying pre-service physics teachers' misconceptions and conceptual difficulties about geometrical optics Kaltakci-Gurel, Derya; Eryılmaz, Ali; MCDERMOTT, Lillian C. (IOP Publishing, 2016-07-01) This study investigated pre-service physics teachers' (PSPTs) misconceptions and conceptual difficulties about geometrical optics in the contexts of plane mirrors (single and hinged), spherical mirrors (concave and convex) and lenses (converging and diverging) using prolonged interviews and an open-ended test. The interviews were conducted in five sessions with a divergent sample of 16 PSPTs, and the open-ended geometrical optics test (OEGOT) was administered to a sample of 52 PSPTs in Turkey. The interview...
Investigation of undergraduate students' mental models about the quantization of physical observables Didiş, Nilüfer; Eryılmaz, Ali; Erkoç, Şakir; Department of Secondary Science and Mathematics Education (2012) The purpose of this research is to investigate undergraduate students’ mental models about the quantization of physical observables. The research was guided by ethnography, case study, and content analysis integrated to each other. It focused on second-year physics and physics education students, who were taking the Modern Physics course at the Department of Physics, at Middle East Technical University. Wide range of data was collected by interview, observation, test, diary, and other documents during 2008-...
Facilitating Conceptual Change in Rate of Reaction Concepts Using Conceptual Change Oriented Instruction KAYA, EBRU; Geban, Ömer (2012-01-01) The purpose of this study was to investigate the effects of conceptual change-oriented instruction through demonstrations (CCOITD) on 11th grade students' understanding of rate of reaction concepts when compared to traditionally designed chemistry instruction (TDCI). The sample consisted of 69 11th grade students from two classes in a public high school. Reaction Rate Concept Test was administered to both groups as a pretest and posttest to assess students' understanding of the concepts. The data was analyz...
A database of PIV measurements within a turbomachinery stage and sample comparisons with unsteady RANS Uzol, Oğuz; Chow, Y.-C.; Katz, J.; Meneveau, C. (Informa UK Limited, 2007-01-01) This paper describes an experimental database obtained using two-dimensional Particle Image Velocimetry (PIV) measurements within an axial turbomachinery stage, and presents sample unsteady Reynolds Averaged Navier - Stokes (RANS) simulations to illustrate its applicability for turbomachinery model validation. The experiments are performed in a refractive-index-matched facility that provides unobstructed view, and cover the entire second stage of a two-stage axial pump. The data were obtained at ten differe...
Development of software for calculations of the reflectance, transmittance and absorptance of multilayered thin films Şimşek, Yusuf; Esendemir, Akif; Department of Physics (2008) The aim of this study is to develop a software which calculates reflection, transmission and absorption of multilayered thin films by using complex indices of refraction, as a function of both wavelength and thickness. For these calculations matrix methods will be considered and this software is programmed with the matrix method. Outputs of the program will be compared with the theoretical and experimental results studied in the scientific papers.
