A survey was developed and implemented to determine how pervasively safety principles and cultural expectations are included in the chemistry curriculum at the undergraduate level. The survey was completed by first-year doctoral candidates in the chemical/pharmaceutical sciences. A majority of the respondents were trained in the use of Safety Data…

Four General Chemistry instructors investigated the use of ChatGPT-4 to improve their lessons plans for the historical experiments of Thomson, Millikan, and Rutherford. The instructors varied in their prior knowledge for these experiments and their initial lessons addressed somewhat different learning objectives. This led to different…

The science process skills of elementary school students in Langsa city are still relatively low, despite these skills being a crucial element in science education based on the Merdeka curriculum. Additionally, teachers have reported several challenges, including the presence of abstract science material, textbooks that use two-dimensional…

The aim of this qualitative multiple case study was to understand three Saudi kindergarten teachers 'attitudes toward enacting inquiry to teach science in the kindergarten classroom. This study was guided by two research questions: 1) What attitudes do Saudi kindergarten teachers hold about using inquiry to teach science in their classrooms? 2)…

The threat of climate change makes it increasingly important for biologists and the public to understand how organisms respond to temperature. The Metabolic Theory of Ecology (MTE) predicts that temperature should affect organism performance, with implications for species interactions and ecosystems that span disciplines including mathematics,…

The role of computation in science is ever-expanding and is enabling scientists to investigate complex phenomena in more powerful ways and tackle previously intractable problems. The growing role of computation has prompted calls to integrate computational thinking (CT) into science instruction in order to more authentically mirror contemporary…

Numerous studies in the educational field show the importance of feedback in the teaching process and students' motivation for learning. Although researchers agree that feedback is essential for improved performance, learners often dismiss it, and its effectiveness is diminished because of specific characteristics of feedback itself, teacher, and…

A systematic review of Threshold Concepts provides a thorough and structured analysis of the existing literature related to these essential and transforming concepts in education. Threshold Concepts represent ideas or knowledge that, once understood, allow the student to access deeper levels of understanding of a discipline. These concepts are…

Digital learning tools and laboratory simulations have been an area of great interest not only due to the advancements of at-home learning but also by allowing students and institutions access to experiences they would not have otherwise due to the high cost of commercial instrumentation. The need for online learning tools became especially…

The double-indicator method is often used in the analysis of Na[subscript 2]CO[subscript 3], NaHCO[subscript 3], and NaOH mixtures (carbonate mixtures). In this method, the determination of the volumes at the first and second equivalence points plays a crucial role in analyzing the composition and content of the carbonate mixtures. Here, LabVIEW…

Photochemical reactions are initiated by the absorption of light, triggering the chemical reactions and resulting in the formation of products. These reactions are generally performed using a freely available renewable source of energy-solar energy. Solar simulators mimic both the ultraviolet and visible regions of sunlight and hence can serve as…

Lateral flow immunoassays have become part of our daily lives as a consequence of the coronavirus pandemic, but what is actually the story behind these red lines? Scientific findings, often described as a scientific black box, create continuous global changes in our living conditions and must be made accessible to society in a comprehensible way.…

Intelligent personal assistants (IPAs) carry massive potential in enhancing students' performance through individualized dynamic scaffolding strategy. Despite IPAs being increasingly recognized among educationists, little is known about their application in the development of students' scientific inquiry skills, particularly in physics. This study…

This study aimed to examine whether withholding answers coupled with physical manipulation of material strengthened by the self-explanation effect (SEE) contribute to the development of a deeper conceptual understanding and retention of learning about motion content in a hands-on (HO) learning environment. The correlation between students'…

The French natural philosopher Henri Victor Regnault (1810-1878) was one of many researchers who contributed to the development of the thermometer in the 19th century. In this paper, we use an example from Regnault's work to explore how the history of thermometry can provide a context for teaching upper-secondary chemistry students about the…
