Although unrecognized for his scientific achievements during his life, Gregor Mendel pioneered our modern understanding of the gene, work that shaped the field of genetics and advances in biology and medicine. The field that he set in motion 200 years ago lies at the center of current ethical debates about the future of humanity, the limits of…

In 1900, three botanists claimed they had found regularities in inheritance, which soon would be known as Mendel's Laws, without knowing the work of Gregor Mendel or of each other. Their claims of independent (re)discovery have been thoroughly studied during the past decades, with various outcomes. The case is still of interest today as it offers…

As a member of the team that created elements 104 and 105 at Lawrence Berkeley Laboratory, James Andrew Harris [1932-2000] was the first African American credited in the discovery of an element. This factoid has been posted on social media, used in a quiz game, and repeated on numerous Web sites. The story (if any context is offered at all) is…

This lesson used the correspondence of Charles Darwin as an exploration of nature of science (NOS) in a historical context. Specifically, we used his original correspondence about his "provisional hypothesis" of pangenesis as a novel way to explore a scientist's social community. Darwin's community of friends and colleagues in the…

Most physics teachers have observed the majestic swings of a monumental pendulum at a science museum and have watched long enough to see the plane of oscillation slowly changing direction as Earth turns. The purpose of Don Olson's article is to describe visits to Paris sites related to Jean Bernard Léon Foucault (1819-1868), with a special focus…

"American Biology Teacher" has published over seven dozen articles relevant to the history of biology in biology teaching. They are cataloged here and indexed by topic. As reflected in this archive, teachers adopt a historical approach for many pragmatic motivations: (1) to engage students, by contextualizing science culturally; (2) to…

Background: Science history is a discipline that teaches the development of scientific thought and the discoveries of scientists. However, these topics can sometimes be abstract and difficult to understand. The use of technology can make the teaching of the history of science more effective, engaging, and accessible. By providing students with…

It has been 150 years since D.I. Mendeleev formulated the Periodic law and expressed it visually in the form of a table of elements in 1869. As is clearly well known today, Mendeleev's ideas, confirmed by the discovery of the elements he predicted, turned out to be very promising indeed. However, Mendeleev was not the first, nor the only scientist…

Ask a physics person what the name of Robert A. Millikan brings to mind, and most would immediately think of the eponymous experiments that he did with the charge on the electron in the years 1908 to 1913. A few might remember his work, starting in 1914, with the experimental determination of Planck's constant using the photoelectric effect. Few…

This study aims to determine the knowledge levels in the Nature and History of Science course of the prospective teachers studying in the science education program and their views following the course. Six interview questions were asked to the pre-service teachers in the science education program about the Nature and History of Science course.…

This paper discusses the emergence of science education in the seventeenth century with the influences of Joseph Priestley on the Dissenting Academies. Primarily, this paper analyses Priestley's ideas from some of his letters to scientists during his time and his ideas from his books "Miscellaneous Observations Relating to Education"…

STEM is a well-known acronym describing the intersections of science, technology, engineering, and math. Emerging from this paradigm is a relatively new interdisciplinary model entitled STEAM. STEAM endeavors to intersperse "the arts" into the sciences with the expectation of increasing student engagement and skills within the sciences.…

Oscillating chemical reactions in the homogeneous phase have been studied intensively only since the mid-1960s, but they were known since 1920, having as forerunners the chemist William C. Bray and an "atypical" chemist Alfred J. Lotka. This contribution is the result of a careful reading of their literature and patient research into…

In this study, the effects of a documentary and a biographical film, which was watched in an informal environment, on the prospective science teachers' nature of science (NOS) views were examined. The study conducted according to the mixed research methodology. The data were obtained through the open-ended questionnaire prepared by considering the…

Many teachers like to introduce the Bohr atom toward the end of an introductory physics course. This is an excellent idea, given the historic importance of Bohr's 1913 work, which provided the bridge from Planck's quantized interaction of matter and radiation (1900) to the full theory of quantum mechanics (1925-28). Unfortunately, the version of…
