In this experiment we have first determined the focal length of an equiconvex lens. We have observed that a real image can be formed by the lens on the same side of the source if the source is sufficiently strong. This is due to the reflection from the concave surface of the lens. We have measured these image distances for different object…

Computers and computer algorithms have contributed to important scientific advances by allowing scientists and engineers to create and use sophisticated models to explain and predict phenomena. Yet, of the eight "Next Generation Science Standards" ("NGSS") science and engineering practices, computational thinking may be the…

The refractive index (RI) is probably the single most important parameter in optical systems. Chromatic dispersion, on the other hand, indicates how the RI depends on the wavelength and is central in, e.g., optical communication systems. Chromatic dispersion also plays an important role when teaching optics due to the captivating natural…

The paper is based on the hypothesis and the assumption that teachers' beliefs and perspectives on teaching have a significant impact on their behaviour in the classroom, as well as that they guide and direct reflexivity in teaching practice. In that manner, the teachers' beliefs and their reflective practice have become the necessary and integral…

The Unlearning Cycle offers a way to help educators identify some of the underlying assumptions and beliefs we bring to our pedagogical design. In a field so focused on learning, it is actually unlearning we need to focus on. This chapter shares research and strategies to trade up for new ways of teaching and designing for inclusive, rigorous…

Physical education is an important venue to develop children's motor competencies and healthy lifestyles. It is concerning that participation rates in secondary physical education classes have been declining in recent years. The decline is often associated with a decreased level of motivation. While many physical educators are struggling with…

In this article, the author opines that bell hooks' deepest, most complex contribution to antiracist teaching is her 2001 book "All About Love: New Visions" rather than titles such as "Teaching to Transgress: Education as the Practice of Freedom" (1994) or "Teaching Community: A Pedagogy of Hope" (2003). The author…

In this article, the author shares her research, as well as the work of other scholars, on social studies education narratives that portray individuals as heroes or villains and the effect these portrayals may have on students. These narratives not only stifle students' feelings of civic agency, but they minimize the role of community in creating…

The wave nature of light has been widely demonstrated in a double-slit experiment, which has played a special role in physics teaching. When monochromatic light passes through the double-slit sheet, the diffraction and interference fringes can be observed in the far-field regime. The interference of light causes the beams passing through the two…

Our discussion addresses Benjamin's antifascist education through the lens of aesthetic education and Herbert Marcuse's aesthetic theory. While this theme is not explicitly discussed in Lewis' book, we argue that it is essential for understanding the full political and educational potential of what he calls "the art of straying in the…

How do educators talk about trauma with young children? Specifically, how do they address children's secondhand experiences of crimes against humanity? In this article, Cara E. Furman argues that classrooms for young children must witness these experiences. A genre of picture books that Furman terms "eavesdropping texts" offer testimony…

This paper draws on the concept of affective atmospheres to theorize how democracy and democratic education take hold and circulate in classrooms and schools. The paper asks under which circumstances affective atmospheres are experienced or even 'engineered', encompassing affective and material features that (de)legitimate democracy, democratic…

In this article, the author details an undergraduate senior seminar titled "History and Literature," for which the main project was a close reading of a big book: Victor Hugo's Les Misérables (1862). Despite reservations about the style of the material, the "great books" approach to teaching, and the challenge of compelling…

Background: Research has established that service-learning is a high-impact practice with significant consequences for student learning. Research in this area can provide greater understanding and recognition of the value faculty bring to the service-learning experience. Purpose: Examining faculty members' memorable experiences in service-learning…

The aim of this article is to present pedagogical inspirations in contemporary art. In pedagogical research and analyses, we more frequently pose questions about the artistic inspirations for educational theory and practice. In the face of the educational turn in contemporary art and culture, it is worth considering inspiration in the opposite…
