An online HTML5 Fourier synthesizer app is provided that allows students to manipulate sixteen harmonics and construct periodic waves. Students can set the amplitudes and phases for each harmonic, seeing the resulting waveforms and hearing the sounds. Five waveform presets are included: sine, triangle, square, ramp (sawtooth), and pulse train. The…

In most high school physics classes, gravity is described as an attractive force between two masses as formulated by Newton over 300 years ago. Einstein's general theory of relativity implies that gravitational effects are instead the result of a "curvature" of space-time. However, explaining why things fall without resorting to Newton's…

In recent years there has been an increasing interest in museum studies in exhibitions on what is termed Difficult Matters (Silvén and Björklund 2006)--such as rape and mass murder--and how such exhibitions may evoke ethical change. This raises the question about the conditions on which such exhibitions can lead to an ethical change. By developing…

Reflecting on one's own emotions and seeing teaching as an emotionally complex engagement can enrich a teacher's experience, pedagogy, and students' motivation and response in class.

In this paper I present various equatorial sundial designs that use diffraction on a CD to display time. The designs described in the paper include a transparent CD sundial equipped with a small terrestrial globe. This sundial is compact, pedagogically useful, can be used throughout the year, and provides the user with a wealth of information.

In this study, we examine how prospective teachers perceive the efficacy of manipulatives and if these perceptions relate to their future use of manipulatives and their mathematics self-efficacy. Survey responses from 97 preservice educators who had completed a mathematics method course indicate three essential findings. One, preservice teachers…

There is a wealth of literature that attests to the benefits of retrieval practice in the long term retention of academic material (see Roediger & Butler, 2011 for a review). Unfortunately, there is also evidence indicating that students rarely report using this method of study (e.g. Karpicke, Butler, Roediger, 2009). The authors have piloted…

The study of English, like the teaching of English, is bound with thematic concerns of love. Notions of love, and the range of experiences that come with them, coalesce in learning spaces when both teachers and students analyse texts, unpack social issues, and construct arguments in daily teaching and learning practice. Within the broader social…

Selecting repertoire that adult piano students find motivating and musically satisfying is more complex than simply finding pieces that are aurally pleasing. Drawing on theories of motivation, adult learning and transformative pedagogy, this practitioner-based study describes how the author learned to involve her students in the selection process,…

In the early 1960s, Peace Corps staff turned to American colleges and universities to prepare young Americans for volunteer service abroad. In doing so, the agency applied the university's modernist conceptions of citizenship education to volunteer training. The training staff and volunteers quickly discovered, however, that prevailing methods of…

Project-based learning (PBL) is a powerful way to make learning meaningful to students and to promote student questions and ownership of the inquiry process. It is a useful way to design and deliver curriculum that is similar in many ways to the Inquiry Design Model (IDM). Although PBL and IDM both value inquiry and student questioning, PBL…

This article proposes a practical method of teaching the addition of unit fractions using a series of mirror equation experiments.

English permits certain non-prototypical sentence forms that have focusing or foregrounding effect. Focus structures place certain elements of the basic version of the sentence in different positions in order to make them more prominent. Due to the widespread usage of them, EFL/ESL teachers should be familiar with the grammar of these structures…

In this article, we draw upon the Conceptual Profile Theory to discuss the negotiation of meanings related to the energy concept in an 11th grade physics classroom. This theory is based on the heterogeneity of verbal thinking, that is, on the idea that any individual or society does not represent concepts in a single way. According to this…

The paper emphasis on the teaching learning process by evaluating the Emotional Maturity and Metacognition of high school teachers. Metacognitive strategies are essential for the teachers of 21st century. This may enable teachers to successfully cope with and handle new situations. For this they should be able to regulate their thinking. So, it is…
