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…

Electricity and magnetism are fundamental areas of physics and are integral to science curricula at various educational levels. However, this area has been reported to contain several concepts that students find challenging, leading to perspectives that diverge from scientifically accepted views. This study examines the errors made by physics…

Chemical thinking has been widely recognized as a core competence that students develop in chemistry education. This study examined the distribution and representation forms of chemical thinking in the five Chinese high school chemistry textbooks aligned with the new national standards in Mainland China. We employed the framework of essential…

Traditional didactic teaching methods in medical education, while foundational, often lead to passive learning and insufficient engagement. "Pancreata--The Keto Struggle," an educational tale-based game for diabetic ketoacidosis (DKA), was developed to address these challenges by promoting collaborative learning, enhancing student…

Elementary teachers require support through professional learning activities to enhance their climate change literacy and bolster their self-efficacy for teaching climate change. This study explores methods for supporting in-service elementary teachers' self-efficacy in climate change teaching by examining the impact of professional learning…

Research shows that when students use core concepts to guide their reasoning, they are able to construct more accurate, mechanistic explanations. However, there is scant research exploring student's perceptions of the usefulness of core concepts. Knowing students' perceptions could be influential in encouraging faculty to adopt core concept…

Mechanistic explanations, aiming to disclose details of entities and their activities, employ the act of unpacking which, inherently and paradoxically, produces explanatory gaps--pieces of undisclosed, undetailed mechanistic information. These gaps, termed explanatory black boxes, are often perceived as counterproductive to the teaching of…

Games are a powerful tool for learning, offering unique benefits for student engagement, particularly when addressing complex or challenging topics. The general public's understanding of how vaccines are made is limited and the general public is unaware of the comprehensive research, development, and safety measures that are inherent in vaccine…

This qualitative multiple-case study examined kindergarten students' engagement in science concepts and literacy learning in a classroom in which these two subjects were integrated through Concept-Oriented Reading Instruction (CORI). CORI is an instructional framework created to increase reading engagement by teaching reading comprehension…

Many simple chemical reactions produce an audible fizz due to the formation of gases, such as oxygen, hydrogen, or carbon dioxide. A hands-on activity based on perceiving these audible chemical changes is presented. The relative quality of fizz due to the formation of gases in a chemical reaction was determined by visually impaired middle and high…

Augmented reality (AR) provides students with visual, auditory, and concrete learning understandings that facilitate their understanding of abstract concepts, leading to positive experiences in the learning process. Positive experiences increase students' motivation and interest in learning. This study examined the effects of using AR technology…

Even though physical experiments are mandatory in science education, there has been an increasing demand for virtual experiments. This research aimed to investigate the impact of virtual experiments compared to physical experiments on students' conceptual understanding of chemical kinetics concepts. To achieve this, a two-phase explanatory…

This research aims to develop a professional development model for science teachers using a school-based approach to enhance STEM literacy. The model leverages outdoor STEM education resources in southern Thailand. The study focuses on primary-level science and project-based teachers in Phuket Province, selected through purposive sampling from…

Despite the challenges posed by expository instruction materials, including unfamiliar text structure and abstracted and isolated representation of the contents, they constitute a primary means of studying scientific concepts in higher education. Conversely, utilizing narratives to present the to-be-learned content was conjectured to mitigate some…

The cosine theorem is used in solving triangulation problems and in physics when solving problems of addition of unidirectional oscillations. However, this theorem is used only for the analytical calculation of triangles or when solving problems of adding two oscillations. Here we propose a generalization of the cosine theorem for the case of…
