Environmental components, including soil, water, air, and biodiversity, are vital for maintaining the balance of the ecosystem. However, environmental pollution is one of the most significant threats to these balances. With environmental pollution, the balance of ecosystems is disrupted, and the food chain is negatively affected. The food chain,…

The purpose of this case study, informed by a Lakatosian perspective, is to identify how an alternative conception that originates in present learning but is related directly to subsequent learning contexts can be constructed. Before the study, one of the authors found by accident that a student who had learned about Avogadro's principle and…

A central objective of science education is to foster a profound comprehension of fundamental scientific principles among students. Research has shown that a highly integrated knowledge structure is a key factor in achieving a deep understanding. This research has developed a friction force conceptual framework to model students' different…

We present two studies to investigate the extent to which attending a planetarium presentation increases secondary school students' understanding of the apparent motion of the Sun and stars. In the first study, we used the Apparent Motion of Sun and Stars (AMoSS) test in a pretest/post-test/retention test setting to measure learning gains and…

With the rise of quantum computing, interest has grown in using two-state quantum systems (qubits) at the secondary level to foster students' conceptual understanding. Quantum measurement, in particular, is central to quantum theory and its accurate conceptualization by students is crucial for grasping fundamental quantum principles. However,…

The construction of scientific explanations is recognised by science education researchers and curriculum developers as one of the core epistemic practices in which students should acquire proficiency. However, little is known about the knowledge and skills that teachers must and do put into practice to successfully engage their students in…

A significant body of scholarship in Physics Education Research (PER) has documented that students have intuitive knowledge resources that they use to make sense of the physical world. Similarly, for physicists, symmetry is fundamental to making sense of the universe. In this dissertation, I explore students' intuitive resources related to…

Energy is a concept frequently encountered both in daily life and in various disciplines. Despite such a wide range of scope, conceptualizing it might be challenging at times. This study aims to investigate high school students' views on the concept of energy through a set of various paper-and-pencil tests. For this purpose, 654 high school…

This article describes how the authors began developing human rights curriculum for, and then teaching, a middle grades book club unit using books with lesbian, gay, bisexual, transgender, queer, intersex, and asexual (LGBTQIA)+ content in an eighth-grade English class. The article highlights how picture books with book clubs can be used to render…

Seeds of Algebraic Thinking comes from the Knowledge in Pieces (KiP) perspective of learning. KiP is a systems approach to learning that stems from the constructivist idea that people learn by building on prior knowledge. As people experience the world, they acquire small, sub-conceptual knowledge elements. When people engage in a particular…

The paper is the result of extensive research carried out among Czech students and focuses on a conception of infinity. The questionnaire survey was taken by 861 students ranging from grades 7 to 13. The aim of the research was to describe the development of students' conceptions of infinity. These conceptions are built on the intuitive phenomenon…

Augmented Reality (AR) enhances education by providing immersive and interactive learning experiences, particularly for students with low spatial skills, as well as in conceptual and procedural knowledge. In the Malaysian Form 2 mathematics curriculum, Isometric Transformation presents significant challenges. Traditional teaching methods often…

The purpose of this study is to analyze the mental model of improvement and changes on light wave concepts with Conceptual Change based on Virtual Media (CC-VM) x POE strategy. The method used is mixed methods with embedded design. The sample consisted of 30 students (with an age range of 16-17 years) in one of the schools in Subang, Indonesia.…

This study investigated children's knowledge of the addition of fractions with unlike denominators. It focussed on the strategies used by children to add fractions with unlike denominators. A cross-sectional survey of Grade 8 children in schools in two districts in Ghana was used. A test on the addition of fractions with unlike denominators was…

When learning about fractions, teaching usually follows certain topics -- e.g. part of the whole, fraction equivalence, and size comparison. Not yet answered is whether students' conceptual and procedural knowledge of fractions is coherent between those topics. To answer this question, we performed a latent profile analysis of data from N = 1005…
