Whilst teaching about the nature of science (NOS) is a significant goal of science education, there remains debate about specifying the NOS and appropriate pedagogies and approaches to researching the NOS. A neglected, but conceptually and practically significant, problem is the proliferation of NOS-related learning goals such as NOS beliefs,…

Background: Immersive virtual reality (IVR) is a new technology that could motivate learners, but also could contain distracting elements that increase cognitive demands on learners. In contrast, learning with conventional media, such as a narrated slideshow could be less motivating, but also less distracting. Objectives: This experiment…

Given the severe pollution caused by traditional plastics, biodegradable plastic products (BPPs) have received great attention and are appearing in people's lives in the form of packaging bags, tableware, etc. Whether a wide variety of BPPs can truly degrade depends on the environment. Aerobic composting is the arbitration method to evaluate the…

Anatomy is the cornerstone of medical education. Virtual reality (VR) and augmented reality (AR) technologies are becoming increasingly popular in the development of anatomy education. Various studies have evaluated VR and AR in anatomy education. This meta-analysis aims to evaluate the effectiveness of VR and AR in anatomical education. The…

This study seeks to elucidate the fundamental principles underlying the hydration, hydrolysis, and enolization of [beta]-diketones, aiming to enhance students' comprehension of the link between fundamental chemical principles and the practical implications of keto-enol tautomerization and diketone-gem diol equilibrium in diverse chemical…

Background: TPACK is a widely used framework for assessing teachers' competence in integrating technology in education. However, previous studies have shown varying interpretations of the relationship between TPACK elements. Qualitative studies that assess the manifestations of TPACK by examining the practices of pre-service teachers are rare.…

Electrophilic aromatic substitution (S[subscript E]Ar) and nucleophilic aromatic substitution (S[subscript N]Ar) reactions are among the most valuable reactions in the conversion of aromatic rings. While these reactions are typically covered in separate experiments in undergraduate organic courses, a continuous experimental setup elucidating both…

A comprehensive chemistry laboratory experiment, including the synthesis of Pt/Al[subscript 2]O[subscript 3] catalysts at different conditions, structure characterization, and the real-world application exploration, has been designed for upper-division undergraduate and graduate students as an expansion and improvement of the professional…

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…
