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…

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…

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…

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…

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…

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…

The philosophy of science (POS) has gained recognition for its contributions to science education, particularly in integrating the history and philosophy of science (HPS). However, the existing literature lacks a comprehensive review that systematically investigates the implications and limitations of POS in science education research. This study…

The study examined preservice teachers' development in conceptions of NOS and their argumentation components using an explicit approach that targets NOS and argumentation. Participants were 20 preservice elementary teachers enrolled in a science methods course emphasizing explicit instruction of NOS and argumentation through various hands-on…

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…

This study examined science teachers' views on the Reconceptualized Family Resemblance Approach to Nature of Science (RFN). Semi-structured individual online interviews including questions related to all categories of the RFN were conducted with eight science teachers to explore their views on the epistemic, cognitive, and social-institutional…

Informed Nature of Science (NOS) conception is among the professional competencies of science teachers. As a result, extensive research is being conducted on the development of NOS conceptions among pre-service science teachers (PSSTs). However, it remains a significant challenge, particularly because NOS is a meta-concept that necessitates…

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…
