The study explored science and science education professors' nature of science (NOS) understandings and perceptions on NOS instruction before (T1), during (T2), and after (T3) a professional development (PD) series. Using repeated measures design, findings showed an increasing trend across NOS aspects. Summary scores were used to classify…

Today, only people, who truly understand what scientific knowledge is and how it is obtained, are considered scientifically literate. This understanding expected in today's scientific areas is called the nature of science (NOS). This study aimed to determine the perceptions of high school students and their parents regarding NOS. In addition, the…

Integrating science and engineering has become a focal point for current research in science and STEM educational fields. Infusing engineering design as an application of scientific principles is beneficial, as it demonstrates an authentic, real-world application and allows for not only student engagement and enthusiasm, but also an avenue to…

With regard to current controversial public discussions about the credibility of scientific knowledge, it seems particularly important that students possess adequate ideas about the tentativeness of scientific knowledge, which is a key aspect of nature of science. However, international studies show that many pre-service science teachers tend to…

What if energy flowed from cold to hot regions? How would thermodynamics be different? We examine such an imagined cold-to-hot world, abbreviated here as a C2H world, and show that the unfamiliar direction of energy flow implies that two thermally interacting objects at different temperatures will not equilibrate. We find that there is no…

If a ball rolls at constant speed on a horizontal surface about a horizontal axis then the angular velocity is easily measured. If the ball is projected with additional spin about the vertical axis, then the rotation axis is tilted and it is more difficult to measure the rotation speed. A few examples are presented to show how the separate topspin…

Physical chemistry students often lack conceptual understanding of the measurable quantities derivatives and integrals represent in particular problems. Also, two-parameter equations of state exhibit horizontal inflections at the critical point in the "PV" isotherms, and students must employ the mathematical properties of inflections to…

Understanding the world around us is a growing necessity for the whole public, as citizens are required to make informed decisions in their everyday lives about complex issues. Systems thinking (ST) is a promising approach for developing solutions to various problems that society faces and has been acknowledged as a crosscutting concept that…

This study aimed to develop a valid and reliable scale that reveals secondary school pupils' attitudes toward science literacy. The survey model, one of the quantitative research methods, was used in the study. The validity and reliability study of the scale was carried out on secondary school pupils attending public schools in Turkey in the…

Scholars as exemplars and their linked eponyms play a significant role in education. Since the discovery of the periodic law in 1869, perceptions of Mendeleev and his eponyms may have shifted. With the aim of assessing the historical and current portrayal of Mendeleev and his eponyms in chemistry textbooks and on the Internet, content analysis of…

Although Ohm's law contains various possibilities in teaching and learning scientific inquiry, it is rare for students to experience an authentic inquiry. Thus, we designed an open-ended in-depth inquiry about Ohm's law and made students conduct it. To do this, we developed a laboratory activity for students following a standard method of Ohm's…

Background: Research on cognitive effects of educational games in general shows promising results. However, there are large variations in learning outcomes between individual educational games. Research on the design process and different design elements of educational games has led to some interesting directions, but some design aspects remain…

Quasi-experimental methods are a cornerstone of applied social science, providing critical answers to causal questions that inform policy and practice. Although open science principles have influenced experimental research norms across the social sciences, these practices are rarely implemented in quasi-experimental research. In this paper, we…

"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…

A science, technology, society, and environmental (STSE) impact assignment framework was developed that bridges the gap between analytical chemistry education and broader societal and environmental contexts. Over the course of [approximately]8 weeks, students were provided with the opportunity to engage in a self-directed learning opportunity to…
