This research investigated the effect of project-based learning (PjBL) on students' conceptual understanding of mechanics. For this purpose, a quasi-experimental research design was conducted with 50 ninth-grade students at Nazarbayev Intellectual School in Kazakhstan. We used the force concept inventory test to measure students' conceptual…

As students read scientific texts created in generative artificial intelligence (GenAI) tools, they need to draw on their epistemic knowledge of GenAI as well as that of science. However, only a few research discussed multimodality as a methodological approach in characterising students' ideas of GenAI-science epistemic reading. This study…

Numerous studies have shown that teaching the history and philosophy of science (POS) can help improve senior high school students' scientific literacy. The history of science is usually taught in school science lessons by reference to particular cases, experiments, and scientists. In contrast, the POS -- that is, the study of general and…

This study examines the characteristics of students' arguments when they are confronted with scientific claims. A qualitative single-case study was conducted to investigate the problem. Data were collected through observations and interviews, using the convenient sampling method in a tenth-grade (n=9) class in Norway. Audio recordings captured the…

This paper aimed to examine the changes in the representations of nature of science (NOS) in Chinese senior high school chemistry textbooks under the influence of the new curriculum ideas. The study was conducted based on an analytical framework in which the aspects of NOS, the approaches to address NOS, and the content relation of NOS aspects…

This report includes the analysis of three chemistry textbooks in high schools in Iran for representation of nature of science (NOS). The analysis was framed by an analytical tool developed and validated by Abd-El-Khalick and a team of researchers in a large-scale study on the high school textbooks in the USA. The results indicated that NOS…

This study investigates the process of students' metacognitive learning about homeostasis, a fundamental biological principle. The research aimed to determine how the metacognitive awareness learning approach (MCLA) affects student perceptions of homeostasis. The research participants were 146 Israeli 10th-grade students (ages 15-16) who were…

Numerous studies have shown that a considerable number of students do not accept the theory of evolution, prompting the scientific community to seek ways to improve how lessons on evolution are designed in order to promote students' acceptance. A crucial factor identified in many studies is students' comprehension of the nature of science and…

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…

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…

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…

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…

In the 21st century, post coronavirus disease 2019 (COVID-19) pandemic, virology has been, and continues to be, in the public eye. The impact of the COVID-19 pandemic globally has affected political, economic, social, policy, and health aspects. Transformative breakthroughs in the field of virology such as disease prevention, vaccines, drug…

Guided by the analytical framework in the current literature, whereby ten nature of science (NOS) aspects were targeted, this study aims at assessing the extent to which the three physics textbooks for Cycle 4 of Fundamental Schools in Burundi represent the NOS aspects. The quantitative embedded research design which combines the qualitative and…

This action research case study explored the ability of three high school chemistry students to grow in their understanding of nature of science (NOS) during its explicit-reflective inclusion in two unit chapters on bonding (ionic compounds followed by covalent molecules). Students completed a pre, post and delayed Views of Nature of Science Form…
