The Young-Feynman two-hole interferometer is widely used to present electron wave-particle duality and, in particular, the buildup of interference fringes with single electrons. The teaching approach consists of two steps: (i) electrons come through only one hole but diffraction effects are disregarded and (ii) electrons come through both holes…

Teachers' classroom-based action research is sometimes misunderstood by those who undertake it and support it, in three respects. First, it is wrongly assumed to fall into either positivist or interpretive paradigms (or perhaps a mixture of both) or to be critical. Second, there is little understanding as to why action research is necessarily…

The "Balance of Nature" metaphor is a pervasive idea in ecology. However, the scientific community acknowledged during the last decades that equilibrium conditions are rare, while disturbance events are not uncommon. We suggest that the exclusive teaching of the "Balance of Nature" metaphor produces cultural, scientific and learning misconceptions…

This article attempts to reconsider and re-evaluate the often misunderstood and mis-conceptualised notion of "progressivism" within education by examining it through the lens of intentionality, specifically the textual kind prescribed by Quentin Skinner in his seminal work "Visions of Politics" (2002). Locating and explicating his ideas will…

The requirement of rotational invariance for lattice potential energies is investigated. Starting from this condition, it is shown that the Cauchy relations for the elastic constants are fulfilled if the lattice potential is built from pair interactions or when the first-neighbour approximation is adopted. This is seldom recognized in widely used…

This study examines the use of inquiry-based instruction to promote the understanding of critical concepts in thermodynamics and heat transfer. Significant research shows that students frequently enter our courses with tightly held misconceptions about the physical world that are not effectively addressed through traditional instruction. Students'…

Undergraduate and graduate students' predictions and submicroscopic level explanations for the melting of four materials (salt, chalk, sugar, and butter), and for the mixing of these solutes in two solvents (water and cooking oil) were collected. Twenty-three undergraduate students and seven graduate students participated in the study, and data…

In an attempt to give a general but critical review of school-based curriculum development (SBCD) in China's new curriculum reform (NCR), this article discusses at length some issues remaining in SBCD, including misconceptions in Chinese discussions about SBCD, most significantly, the Chinese literal expression of the policy statement on…

Dinosaurs in the middle school classroom can be exciting. These extinct reptiles are both an exotic subject and familiar to our students. Because students are inherently interested, dinosaurs can serve as an effective portal for the integration of biology, geology, ecology, and the history and nature of science. The field of dinosaur study is…

Originally designed for K-12 teachers, the Understanding Evolution (UE) Web site ("www.understandingevolution.org") is a one-stop shop for all of a teacher's evolution education needs, with lesson plans, teaching tips, lists of common evolution misconceptions, and much more. However, during the past five years, the UE project team learned that…

To test the effects of octave and timbre on tuning accuracy, four stimuli--B-flat 4 sounded by flute, oboe, and clarinet and B-flat 2 sounded by tuba--functioned as reference pitches for high school wind players (N = 72). The two stimulus octaves combined with participants' assigned tuning notes created soprano, tenor, and bass tuning groups. All…

The purpose was to examine how caregivers of infants and toddlers with autism spectrum disorder view their daily activities/routines and in what way, if any, assistive technology (AT) acts as a support. A total of 134 families who reported their child's disability as autism spectrum disorder/pervasive developmental disorder completed a survey…

Eighteen middle and high school students with visual impairments participated in a weeklong field-based geology summer camp. This paper reports the curriculum, strategies, and what the students learned about Earth science by climbing in and out of caves, collecting fossils, exploring a bog, and interacting with experts in the field. Students were…

The process of conceptual change can be described as a three phase process. The first phase involves students' possession of initial naive "conceptions/misconceptions," the second phase involves students undergoing a process of "assimilation," and the third phase involves students undergoing a radical process called…

In this paper, I argue that Friedrich Nietzsche's concept of self-overcoming has been largely misinterpreted in the philosophy of education journals. The misinterpretation partially stems from a misconstruction of Nietzsche's perspectivism, and leads to a conception of self-overcoming that is inconsistent with Nietzsche's educational ideals. To…
