This essay is a critique of medical/clinical ethics from the personal perspective of a medical historian in an academic health science centre who has interacted with ethicists. It calls for greater transparency and accountability of ethicists involved in "bedside consulting"; it questions the wisdom of the four principles of biomedical…

I investigated two late 19th-century methods for capturing magnetic field images from iron filings for historical insight into the pedagogy of hands-on physics education methods, and to flesh out teaching and learning practicalities tacit in the historical record. Both methods offer opportunities for close sensory engagement in data-collection…

This paper discusses the levels of The Instructional Model for Using History of Science (UHOS) to explain the relationship between the history of science and science teaching. The UHOS model proposes four levels: Conceptual Level, Epistemological Level, Sociocultural Level, and Interest Level. Each Level has sublevels with regards to types of…

This paper describes a method for teaching planetary retrograde motion, and the Ptolemaic and Copernican accounts of retrograde motion, by means of a series kinesthetic learning activities (KLAs). In the KLAs described, the students literally walk through the motions of the planets in both systems. A retrospective statistical analysis shows that…

This article discusses a number of aspects of the nature of science that can be illustrated by considering the development of pangenesis, a principle proposed by Charles Darwin to describe the rules of inheritance, explain the source of new variation, and solve other natural history puzzles. Pangenesis--although false--can be used to illustrate…

In recent years, school science has been the target of increasing critique for two reasons. On the one hand, it is said to enforce "epic" images of science that celebrate the heroes and heroic deeds that established the scientific canon and its methods and thereby falsifies the history and nature of science. On the other hand, the…

Despite its popularity in education studies literature, interdisciplinary science education is mostly considered outside the multitude of social forces that drive education reform. This has contributed to a mythologizing of interdisciplinary science education and lead to assumptions about the necessity of its intervention into science education…

The experiment in which a candle is burned inside an inverted vessel partially immersed in water has a history of more than 2,200 years, but even nowadays it is common that students and teachers relate the change in volume of the enclosed air to its oxygen content. Contrary to what many people think, Lavoisier concluded that any change in volume…

One major obstacle for integrating the history of mathematics in teaching (hereafter referred to as IHT) is how to help teachers, particularly those who lack experience in IHT, use historical materials in their teaching. Based on many IHT practices in Shanghai, this paper proposes an IHT framework including two parts: one is a triangular pyramid…

The history of science is an important component to acquire for achieving scientific literacy. In this study, a collaborative activity was applied in which the students were presented with the historical context in which Robert Hooke lived and developed the first register of the microscopic world. Furthermore, the students explored the environment…

In response to a reader query, this article traces the history of fusible alloys, including Newton's metal, D'Arcet's metal, Rose's metal, Onion's fusible alloy, and Wood's metal. (Contains 1 table and 1 figure.)

Throughout the nineteenth century, the sciences in the United States went through many professional and disciplinary shifts. While the impact of these changes on university education has been well established, their consequences at the level of high school education have been often overlooked. In mathematics, debates at the level of university…

The nature of light and how it is affected by gravity is discussed. Einstein's prediction of the deflection of light as it passes near the Sun was verified by observations made during the solar eclipse of 1919. Another prediction was that of gravitational redshift, which occurs when light emitted by a star loses energy in the gravitational field…

This article is about a late 19th-century teacher of secondary school physics. I was originally interested in the apparatus that he sold. This led me to the physics books that he wrote, and these took me to his unusual ideas about ways to use laboratory time to introduce students to the phenomena of physics. More than 100 years later educational…

In this study, the historical development of experimental research on learning processes from scientific texts has been introduced. Then a detailed analysis of the main contributions of cognitive science has been provided and the theoretical developments that are considered to have had a major role in the comprehension and understanding of…
