The study addresses professional vision, including the abilities of selective attention and knowledge-based reasoning. This article focuses on the latter ability. Groups with different sport-specific and pedagogical expertise (n = 60) were compared according to their observation and interpretation of sport activities in a four-field design. The…

This study sought to investigate the identity construction of Indonesian Montessori teachers. The research was done in two Montessori schools in Yogyakarta: Cosmic School and Universe School (pseudonyms). The participants involved in this research were eight teachers in total. The data gathering process employed questionnaire, classroom…

It's not surprising that rainbows have received a great deal of attention: in textbooks, in magazines, and on the web. They are, after all, beautiful, fascinating, occasionally awe-inspiring, even a little mysterious. They are an almost perfect blend of natural beauty and simple physics. Has everything that can be said about rainbows already been…

The article "Personal Coaching: A Model for Effective Learning" (Griffiths, 2006) appeared in the "Journal of Learning Design" Volume 1, Issue 2 in 2006. Almost ten years on, Kerryn Griffiths reflects upon her original article. Specifically, Griffiths looks back at the combined coaching-learning model she suggested in her…

A lab was developed for use in an undergraduate honors and majors general chemistry laboratory to introduce students to optics, spectroscopy, and the underlying principles of quantum mechanics. This lab includes four mini-experiments exploring total internal reflection, the tunneling of light, spectra of sparklers and colored candles, and emission…

The use of Virtual Reality (VR) as an educational tool is gaining attention due to its potential to provide immersive and authentic learning experiences. However, most schools cannot afford to provide individual access to VR, making VR-mediated group learning a promising solution for those with limited access to educational resources. Despite its…

We discuss some simple experiments dealing with intriguing properties of light and its interaction with matter. In particular, we show how to emphasize that light reflection, refraction and scattering can provide a proper, physical description of human perception of the "colour" white. These experiments can be used in the classroom with an enquiry…

While most of us probably don't think of teachers as scientists, the truth of the matter is that teachers actually follow many of the scientific processes that scientists use to help them be effective. Teachers have to find ways to measure student learning and to use that measurement to inform their teaching practices. They need to know what…

Women and minorities remain underrepresented in chemistry bachelor's degree attainment in the United States, despite efforts to improve their early chemistry achievement through supplemental academic programs and active-learning approaches. We propose an additional strategy for addressing these disparities: course-based, social-psychological…

Higher education institutions in the United States are experiencing tremendous growth of international students. This essay serves as a case study of how an institution is addressing its growth from a handful of international students to nearly 10% of its total student population in a decade. The authors describe writing instruction and the lack…

This piece critically follows David Bakhurst's 2009 article "Reflections on Activity Theory" in light of recent developments in the field. It sketches three directions for further research. First, it examines his identification of "two strands" of activity theory (AT)--the philosophical, which he associates with E.V. Ilyenkov…

This article takes a psychological perspective on organisational learning, putting "reflection" into the centre of attention. We argue that (1) organisational learning is based on individual and team learning at work, (2) reflection is the driving force that leads to organisational learning and (3) cumulation of the staff's reflection outcomes…

Measuring the refractive index "n" of a substance or medium is part of every introductory physics course. Various approaches to determine this index have been developed over the years based on the different ways light reflects and transmits in the medium. In this paper, the authors would like to present a simple geometrical derivation of the…

In order for teachers to implement inquiry-based teaching practices, they must have experienced inquiry-based learning especially during science content and methods courses. Although the impacts of inquiry-based instruction on various cognitive and affective domains have been studied and documented little attention has been paid to "how"…

Attempts to connect the seemingly disjointed points of view of diffraction and reflection. Light is reflected off of a metal fence, which acts as a grating. Notes that grating with zero spacing between the grating elements acts as a reflector. (MVL)
