The Double Asteroid Redirection Test (DART) is a National Aeronautics and Space Administration--European Space Agency collaborative mission to test the feasibility of defending Earth from a catastrophic asteroid impact by using a spacecraft to deflect the asteroid away from the planet. Launched on Nov. 23, 2021, the DART spacecraft will intercept…

Cell size is an important variable in the study of cellular growth, metabolism, and the cell cycle. The large size of "Amoeba proteus" and the ease with which it can be collected and cultured have made it a star in biology education--and it was a model for research on cell biology before the introduction of molecular genetic methods.…

Ampère's law is presented in introductory physics as a relation between the line integral of the magnetic field around a closed loop and the net current crossing any open surface spanning that loop. By allowing the surface to pass between the plates of a charging parallel-plate capacitor, Maxwell realized that this law is incomplete and introduced…

A straightforward experimental set-up, requiring a two-liter bottle, a ruler and a stopwatch, is used to provide data appropriate for modelling with Torricelli's Law in the simplest case, and a more sophisticated differential equation when losses are taken into account and a pipe extension is considered. With only an exit hole included in the…

Background: The views of the nature of science (VNOS) is one of the important goals of science education. According to information processing constructivism, learners' psychological factors that may influence VNOS include scientific argumentation (SA), metacognition (MC) and epistemic beliefs (EB). Purpose: This mixed-methods study aims to analyse…

The purpose of this study is to see how the inquiry-based nature of science (NOS) argumentation (IB-NOSA) instructional model affects scientific literacy skills. This research used a quasi-experimental method. The design of this research is a pretest-posttest control group design. This study describes the significance of the differences between…

Despite decades of research, NOS is still rarely explicitly and accurately taught in K-12 schools (Abd-El-Khalick & Lederman, 2023). Teachers often address NOS ineffectively as a result of inadequate knowledge of NOS and science content (Wahbeh & Abd-El-Khalick, 2014) as well as NOS pedagogy (Hanuscin et al., 2011). A variety of contextual…

There is often a steady trajectory of curriculum change under the surface of developments that might seem arbitrary or inconsistent. This article traces the change from key competencies to science capabilities and, most recently, to enduring competencies. All these changes (and names) respond to increasing awareness of the challenges involved in…

Understanding nature of science (NOS) is integral to the development of students' scientific literacy. While NOS studies are growing worldwide, none of these reported on the views of secondary school learners in the Philippines. Hence, this study examined the Filipino junior high school (JHS) students' views of the NOS and determined whether…

Purpose -- This study is part of a comprehensive investigation conducted in Malaysia, examining science teachers' understanding of the Nature of Science (NOS) and their ability to translate this knowledge into Pedagogical Content Knowledge (PCK) for NOS. This paper specifically examines how teachers apply their NOS knowledge to develop NOS PCK in…

The purpose of this study is to determine which features of the nature of science pre-service primary school teachers refer to while making a decision on a socioscientific issue at the end of the explicit reflective nature of science education. For this purpose, an exploratory qualitative research design was used in the study. The research group…

Research indicates that students' interest in science decreases during their school years. To counteract this, a quasi-experimental instructional intervention was designed in which we addressed students' leisure interests to foster their (situational) interest in physics. Students in the intervention group got the opportunity to choose topics…

The present study investigates how Greek in-service secondary education biology teachers understand the unique features of school biology and physics when considering the biological theoretical edifice and method. Our theoretical framework focuses on important differences that exist between the neo-Darwinian and Newtonian worldviews, while our…

Graduates in biology or genetics learn Mendel's laws and Hardy-Weinberg equilibrium as students, and they know, use, and sometimes teach these concepts. However, it is unusual to learn about stochastic processes during the graduate studies of these topics, although the applications of Markov chains in the fields of genetics or biology are…

As an introduction to sound and vibration, the authors wanted their first-grade students to plan and conduct their own investigations. In this article, the authors share a series of investigations to help students explore the relationship between sound and vibration. By planning, creating, testing, adapting, and reflecting on the outcomes of the…
