Environmental stewardship education, as a locally oriented concept, benefits from being recast to account for the emergent, multidimensional, and interdisciplinary nature of today's most pressing socio-ecological issues. In an effort to infuse environmental stewardship education with global citizenship, instructional materials on community-based…

This study examines the epistemic disciplinary knowledge that students consider when addressing a real food emergency that requires their engagement in inquiry and argumentation practices. The study comprised two phases: (1) designing an experiment to study the emergency and (2) evaluating the real outcome of the emergency. The participants were…

This research aims to analyse students' conceptual understanding of chemical equilibrium matter using Physics Education Technology (PhET) Interactive Simulations. Students' misconceptions can be caused by the difficulty in connecting the sub-microscopic, macroscopic, and symbolic levels of understanding in chemistry. The study was conducted at a…

Seventeen years after the end of the Liberian civil war, which is partly blamed for the waning of the standard of education, the country is still grappling with providing a competency-based science educational experience that will enhance the science inquiry process skills of its youth. In this paper we used the constructivist theoretical…

The purpose of this mixed-method study is to determine the effect of integrating Engineering design on high school students' scientific reasoning and science achievement. Thirteen eleventh-grade students participated in this eight-week long study. The intervention engaged students in the Engineering design of a functional Dialysis model. Students…

"Instructional Sequence Matters, Grades 9-12" is the one-stop resource that will inspire you to reimagine your approach to high school physical science. The book discusses the 5E (Engage, Explore, Explain, Elaborate, and Evaluate) as a specific pathway for teaching and learning. It also shows how simple shifts in the way you arrange and…

The purpose of this study was to investigate the relationship between the nature of small group discussion tasks and learners' talk during Physical Science lessons. The study was conducted during Physical Science lessons with three self-selected groups of Grade 11 learners from one school. A total of three lessons were followed. During the…

It is difficult for students to learn the concepts of chemical laboratory safety education from actual experiences because the traditional teaching model prohibits students from performing dangerous operations. Therefore, this study develops a novel mixed reality-based chemistry experiment learning system (MRCELS) to allow learners to conduct…

This paper presents an analysis of the socio-scientific dimensions which 46 11th graders, enrolled in the subject scientific culture, consider to justify their COVID-19 vaccination decision and how they managed to combine and integrate these dimensions before and after working on a sequence of activities aimed at learning about argumentation in…

How do scientists make inferences for something they cannot directly observe? The Black Box approach seems ideal to help students understand how scientists work. Black Boxes are sealed units; their interior is not accessible. The effort to determine their possible content (internal structure) demands successive modifications in hypothesis,…

Meaningful understanding of chemistry, among others, includes the ability of an individual to think simultaneously at macroscopic, submicroscopic and symbolic levels, and this presupposes the competence to translate between different types of chemical representations. In this study, we investigated 11th grade Greek students' and 3rd year…

The recent inclusion of the "Depth Study" in the New South Wales (NSW) Years 11 and 12 science curriculum has generally been well received by secondary science education leaders. The Depth Study is designed to present an opportunity for students to engage in inquiry-based learning (IBL). However, the integration of this new curriculum…

This research focuses on chemistry teachers' enacted pedagogical content knowledge (ePCK) in equilibrium in chemical reactions. The enactment dimension of this pedagogical content knowledge (PCK) encompasses enacted knowledge and skills as well as those embedded in practice concerning the Refined Consensus Model of PCK, the most recent PCK model…

Teaching through a second language (L2) poses many challenges, as second language learners (SLLs) have fewer linguistic resources in the language of instruction. Scaffolding students' learning is a possible way of overcoming these challenges, but there are few studies on this in Content and Language Integrated Learning (CLIL) contexts. The present…

In this study, high school physics textbooks published by People's Education Press (PEP) and Educational Science Publishing House (ESP) (a total of 6 books) in China were analyzed via a self-developed scale measuring nature of science (NOS) including three first-level indicators of scientific knowledge, scientific process, and scientific…
