The classic demonstration illustrating Lenz's law by dropping a magnet through a copper pipe is presented using household aluminum foil right out of the box. Then comes the surprise. The teacher presents an aluminum foil cylinder with a missing lengthwise slice (cut before class). Will the demonstration still work? Students are amazed at the…

Consider a chain of length L that hangs in a U shape with end A fixed to a rigid support and free end E released from rest starting from the same initial height (call it y = 0) as A. Figure 1 sketches the chain after end E has fallen a distance y. Points O and A are assumed to be close enough to each other and the chain flexible enough that the…

A new visual representation for insight problems permits 22 new quantitative measures; which leads to a detailed diagnosis of a person's (or team's) creative weaknesses; which then leads to prescribing targeted, effective counter-techniques for each weakness. Currently, only two measures are consistently used for insight problem solving: the…

Folk tales composed of poetry and prose, have succeeded to come until today by various narrators. These stories which especially contain heroism and love stories carry the accumulation of the Turkish society such as belief, experience, art and law. Many societies, including European countries are concerned about the growth of generations that are…

In 1936, Albert Einstein wrote a brief article where he suggested the possibility that a massive object acted as a lens, amplifying the brightness of a star. As time went by, this phenomenon--known as gravitational lensing--has become a powerful research tool in astrophysics. The simplest and symmetrical expression of a gravitational lens is known…

Alex Ford and Richard Kennett both welcome the renewed emphasis on knowledge within recent curriculum reforms in England, but are concerned about some of the ways in which the principle of a 'knowledge-rich' curriculum has been interpreted and transformed into particular pedagogical prescriptions. In this article they explain their reasons for…

In this paper, I explore the problems of cultivating a critical attitude in pedagogy given problems with accounts grounded in critical social theory, rational liberalism and pragmatic esthetic theory. I offer instead an alternative account of criticism for education in open, pluralistic, liberal, democratic societies called 'pedagogy of…

The standard technique taught in calculus courses for partial fraction expansions uses undetermined coefficients to generate a system of linear equations; we present a derivative-based technique that calculus and differential equations instructors can use to reinforce connections to calculus. Simple algebra shows that we can use the derivative to…

In this article, we seek to unpack and enrich the notion of the design concept. We do this through the use of Gilles Deleuze and Felix Guattari's 'concept' in its philosophical specificity to critique less-effective uses of the design concept. In particular, we investigate the idea that a concept is actually an aggregation of many concepts that…

Singing has a profound effect on the child's mental and emotional development and is directly related to the basic mental functions and physiological development. In this context, it is considered that voice training with the aim of using the voice correctly and effectively is necessary in the general music education and breathing and voice…

Music educators share the responsibility of preparing students to become global citizens by providing equal and fair access to a music education through a socially just music classroom. Music education scholars advocate that instead of trying to define social justice or trying to achieve it in the classroom, educators should ask themselves how…

The literature concerning students' understanding of the equal sign has focused narrowly within the context of formal mathematics. Researchers have put forth a hierarchy of conceptions of the equal sign with only the top level regarded as correct. Meanwhile, we find that the equal sign is used widely and in a variety of ways in advertising and…

The Circle of Insight is a dialectical, open, purposeful, and enlightening process that moves those engaged toward deeper, liberating insight. It is a pedagogical construct I created over the past 15 years that I have used in teaching and developing my social justice social work classes. It integrates a see, reflect, act cyclical process that is…

Current research into reflective pedagogy in dance almost exclusively discusses the tertiary education population. Additionally, the research is primarily focused on concert modern dance and creative dance pedagogies, techniques, and choreography. Ballet technique programs in precollegiate populations have, so far, been left out of the…

The changing demographics of U.S. society have prompted a focus on multiculturalism in today's classrooms. Educators and students are expected to be aware of the individual differences and characteristics that exist and use these attributes to everyone's advantage. This awareness begins with developing a broad understanding of the diverse…
