Linares, J.; Nistal, M. C. – European Journal of Physics, 2011
We present a derivation of the paraxial geometrical laws starting from a wave-optics approach, in particular by using simple continuity conditions of paraxial spherical waves at boundaries (discontinuities) between optical media. Paraxial geometrical imaging and magnification laws, under refraction and reflection at boundaries, are derived for…

Chen, Jian; Smith, Andrew D.; Khan, Majid A.; Sinning, Allan R.; Conway, Marianne L.; Cui, Dongmei – Anatomical Sciences Education, 2017
Recent improvements in three-dimensional (3D) virtual modeling software allows anatomists to generate high-resolution, visually appealing, colored, anatomical 3D models from computed tomography (CT) images. In this study, high-resolution CT images of a cadaver were used to develop clinically relevant anatomic models including facial skull, nasal…

Layton, William – Physics Teacher, 2011
Students are often unaware of the little tab on a rear-view mirror that is used to dim headlights from the rear. Those who know about this tab are usually interested in knowing how it works. Explanations of the optics involved can be found in Serway and Jewett and Jones and Edge. An alternate explanation is given.

Silva, Cibelle Celestino; Moura, Breno Arsioli – Science & Education, 2012
The present paper presents a historical study on the acceptance of Newton's corpuscular theory of light in the early eighteenth century. Isaac Newton first published his famous book "Opticks" in 1704. After its publication, it became quite popular and was an almost mandatory presence in cultural life of Enlightenment societies. However, Newton's…

Çildir, Sema – EURASIA Journal of Mathematics, Science & Technology Education, 2016
Factors such as innovations brought in by the developing technology, also rapidly changing social structures casted various roles to both the student and the teacher. Therefore, it is necessary to associate such knowledge acquired in courses with implications of the knowledge in our real lives and to constantly enrich course contents, namely to…

Jewett, John W., Jr. – Physics Teacher, 2016
This is the second in a series of two articles on using antique devices to teach introductory physics. As mentioned in the first article, students can more clearly see the physics required for the operation of antique devices than for modern-day technological devices. This article further discusses antiques used to teach vibrations and waves,…

Verpoorten, Dominique; Castaigne, Jean-Loup; Westera, Wim; Specht, Marcus – Education and Information Technologies, 2014
This paper describes how a short, repeated and structured opportunity to reflect was integrated in the storyline of a serious game in order to stimulate the development of a meta-cognitive skill: the ability to self-assess the degree of confidence in own answers. An empirical validation of the approach, conducted with 28 secondary school pupils,…

Cabeza, Cecilia; Rubido, Nicolás; Martí, Arturo C. – Physics Education, 2014
Entertaining and educational experiments that can be conducted in a water park, illustrating physics concepts, principles and fundamental laws, are described. These experiments are suitable for students ranging from senior secondary school to junior university level. Newton's laws of motion, Bernoulli's equation, based on the conservation of…

Sise, Omer; Manura, David J.; Dogan, Mevlut – European Journal of Physics, 2008
The interactive nature of computer simulation allows students to develop a deeper understanding of the laws of charged particle optics. Here, the use of commercially available optical design programs is described as a tool to aid in solving charged particle optics problems. We describe simple and practical demonstrations of basic electrostatic…

Price, Kelly J.; Shiffrar, Maggie; Kerns, Kimberly A. – Research in Autism Spectrum Disorders, 2012
To determine whether motor difficulties documented in Asperger's Syndrome (AS) are related to compromised visual abilities, this study examined perception and movement in response to dynamic visual environments. Fourteen males with AS and 16 controls aged 7-23 completed measures of motor skills, postural response to optic flow, and visual…

Greenslade, Thomas B., Jr. – Physics Teacher, 2012
In the fall of 1999 I was shown an Ocean Optics spectrometer-in-the-computer at St. Patricks College at Maynooth, Ireland, and thought that I had seen heaven. Of course, it could not resolve the sodium D-lines (I had done that many years before with a homemade wire diffraction grating), and I began to realize that inside was some familiar old…

Chu, Hye-Eun; Treagust, David F. – Journal of Science Education and Technology, 2014
This study focuses on elucidating and explaining reasons for the stability of and interrelationships between students' conceptions about "Light Propagation" and "Visibility of Objects" using contextualized questions across 3 years of secondary schooling from Years 7 to 9. In a large-scale quantitative study involving 1,233…

Kawalec, Tomasz; Bartoszek-Bober, Dobroslawa – European Journal of Physics, 2012
An experimental setup allowing the observation of two-laser interference by the naked eye is described. The key concept is the use of an electronic phase lock between two external cavity diode lasers. The experiment is suitable both for undergraduate and graduate students, mainly in atomic physics laboratories. It gives an opportunity for…

Go, Johnny C. – Teachers and Teaching: Theory and Practice, 2012
This paper examines Donald Schon's critique of Herbert Simon's "science of design" to determine whether later developments in Simon's thought--particularly, his theories of "bounded rationality" and "goal-less designing"--can contribute to an appreciation of Schon's notion of reflective practice. The paper then argues, that viewed through the…

Taslidere, Erdal; Eryilmaz, Ali – Research in Science Education, 2012
The primary purpose of this study was to investigate the combined and partial effects of the Integrated Reading/Study Strategy and Conceptual Physics Approach on ninth grade private high school students' achievement in and attitudes toward optics. The Integrated Reading/Study Strategy is a new strategy which was developed by integrating previously…
