The French natural philosopher Henri Victor Regnault (1810-1878) was one of many researchers who contributed to the development of the thermometer in the 19th century. In this paper, we use an example from Regnault's work to explore how the history of thermometry can provide a context for teaching upper-secondary chemistry students about the…

Developing students' understanding of and about science is an important educational goal. Learning the nature of science (NOS) has been recognized as a critical component of science literacy, affecting how students (our future citizens) make informed decisions. Textbooks can be useful teaching materials if the content presented aligns with…

The principle of relativity is of fundamental importance in practice when we are solving problems in physics since the axiom states that the result of any physical experiment is the same when performed with identical initial conditions relative to any inertial coordinate system. Hence, conceptual knowledge of coordinate systems is central in any…

A simple photometric device was built to measure the kinetics of the title reaction. The device consisted of a green light-emitting diode (centered at 520 nm), a sample vial, a photodiode, and an Arduino microcontroller board. These parts were mounted on a black poly(lactic acid) holder which was manufactured by utilizing three-dimensional…

The law of conservation of momentum is a fundamental law of nature. It states that the momentum of an isolated system is conserved. In high school or introductory-level physics courses, for simplicity, teachers and textbooks always use collisions in one dimension as the examples to introduce the concept of conservation of momentum. To solve simple…

In this work, we present an experimental approximation to the study of the phenomenon of radioactivity in secondary schools, taking as an analogy the process of release of carbon dioxide in a carbonated beverage. In this way, we intend to facilitate the approach to the mathematical formalism and to the graphical description of this phenomenon, as…

Newton's laws are a ubiquitous topic in introductory physics instruction. One common problem involves asking what will happen if you stick your finger into a cup of water sitting on a scale. A way to solve the problem would be to first recognize that the water exerts a buoyant force upward on the finger, which students can recognize as being the…

The existing literature lacks a precise understanding of how online facilitation and dialogic discussions can positively impact students' comprehension of the Nature of Science (NoS). This study delves into the experiences of students and facilitators engaged in synchronous and asynchronous online dialogic discussions and e-facilitation to enhance…

Chinese 2017 General High School Physics Curriculum Standards explicitly include understanding the nature of science (NOS) as core literacy for students. History, philosophy of science, and sociology of science (HPSS) education is an important way to promote students' understanding of the nature of science. In this context, this study analyzed the…

The purpose of this study is to examine how students may hold coexisting and competing conceptual ideas and how students' uses of such ideas may evolve during the process of conceptual change by combining two complementary methods including model analysis and the conceptual framework model of knowledge integration. Conceptual change is fundamental…

High school students' difficulties with quantum physics (QP) are partly due to their limited understanding of the nature of science (NOS). The essence of QP can only be understood with informed views about NOS aspects such as the role of models and the relevance of controversies between physicists. Inversely, QP is an ideal topic for teaching…

Nature of Scientific Knowledge (NOSK) and Nature of Scientific Inquiry (NOSI) are important components of scientific literacy and important educational objectives in science education. Recent literature theorizes that understanding both NOSK and NOSI increases students' understanding of science content knowledge. However, this assumption has yet…

The COVID-19 pandemic provides an opportunity for teachers to explicitly address nature of science (NOS) themes during instruction. Aligned with key NOS categories in the "Next Generation Science Standards," this article discusses events and trends from the pandemic that teachers can use to help students understand values and methods of…

Developing students' understanding of the nature of science (NOS) is seen as critical for educating scientifically literate citizens, and has emerged as an important curricular goal internationally. In Norway, a new curriculum reform has recently been implemented, intended to improve the Norwegian education in several ways. The reform aims to…

Regular disciplinary instruction of introductory physics at high school often misses a holistic perspective of the subject matter, its structure, and hierarchy. We have considered the domain of classical mechanics as taught at school and provided such a perspective in the form of a summative lecture which frames content in the triadic structure…
