The concept of relative density is introduced in the middle school and high school curricula by an intuitive approach based on the phenomena of immersion and flotation. In high school, the same concept is taught as the ratio between the masses of two bodies of the same volume. This dichotomy of the concept of relative density between the two…

Astronomy has great potential to attract children toward science and improve their scientific literacy. However, it has a relatively small presence within the school curricula worldwide. In Chile, home of the world's largest telescopes, astronomy is even more relevant in science education, but the presence of astronomical content within the…

Understanding ecological concepts is crucial in tackling environmental issues like climate change, pollution, and habitat destruction. These concepts also serve as a teaching framework, encouraging learners to effect positive change. This research was conducted with grade 9 learners from three schools in Bloemfontein, South Africa, randomly…

The aim with this study was to analyse and explore how physical sciences, engineering science and technology subjects (technical electrical technology, technical civil technology, technical mechanical technology) can contribute to the alignment of the technical sciences curriculum. We used document analysis to collect data. An analysis of the…

'A lack of prior knowledge in the other discipline' is often given by geoscience instructors to explain why students struggle to apply knowledge from other disciplines to the Earth. We examine this assumption by considering the disciplinary crossing of buoyancy (physics) to isostasy (geoscience). We investigate the teachers' perspective through…

STEM education is on demand more than ever as the workforce relies on 21st century skills and STEM disciplines. This paper presents a framework (IMS-TEAM) for integration of mathematics and science with the use of technology and modeling in an authentic context. The activity based on this framework is designed for and implemented with forty-four…

The Anthropocene is a geo-stratigraphic unit of the upper Earth's layers, impacted by human disturbances, but also humankind's historical record, and children's place to live on. It is an unfinished narrative. This study explores how garden and soil-related activities with kindergarten children, guided by well-informed teachers, may have the…

This paper, presented in three parts, overviews the current understandings of the Earth System and the relatively recent interdisciplinary field of Earth System Science (ESS) from a school education perspective. The representation of ESS in the Australian Curriculum is explored through the Cross Curriculum Priority area of Sustainability and the…

Reconceptualized Family Resemblance Approach to Nature of Science (RFN) explains science as a cognitive, epistemic, and social institutional system. The aim of this study is to examine the inclusion of Nature of Science (NOS) in the 5th, 6th, 7th, and 8th grade Turkish middle school science textbooks. The "content," "activity,"…

In an effort to promote integrated STEM education, the Malaysian government has integrated STEM teaching framework within the science and mathematics curriculum specifications to guide the science and mathematics teachers to design and implement interdisciplinary teaching while teaching science and/or mathematics concepts. Some of the factors that…

Universities are recognizing the need to prepare graduates to think conceptually and have the ability to take on complex, real-world problems. Strategies to assess conceptual knowledge are limited and often require more time and effort to complete than is accessible for most undergraduate courses. Card sorting is a very broad technique for…

The integrated STEAM approach arises when a contextualized problem's resolution requires different contributions (views) from each discipline. In this descriptive article we discuss the views needed from chemistry, technology, design skills, mathematical modelling and the artistic support necessary for constructing a scientific model that explains…

This study explores the integration of STEM principles into chemistry education through the redesign of the topic Chemical Reactions for initial teacher training. The aim was to develop and evaluate an innovative teaching module that fosters key competences--knowledge, skills, and attitudes--via student-centred, context-based, and…

The integration of mathematics and science in teaching facilitates student learning, engagement, motivation, problem-solving, critical thinking, and real-life application. Although curriculum integration is theoretically desirable for many educators, what to integrate and how to integrate are often the big questions facing teachers working within…

Society needs transdisciplinary citizens with good scientific literacy. One way to achieve this could be through the use of areas or subjects for which students have more affinity and expertise. This study seeks to maximize the chemistry learning of students who want to be musicians, through the use of analogies. Analogies are a powerful tool to…
