We investigate the multilingual and multimodal performance of a large language model-based artificial intelligence (AI) system, GPT-4o, using a diverse set of physics concept inventories spanning multiple languages and subject categories. The inventories, sourced from the PhysPort website, cover classical physics topics such as mechanics,…

A systematic literature review across multiple scientific disciplines was conducted to explore students' understanding of atomic structure, focusing on students' ACs. A total of 112 publications between 1972 and 2023 were selected for the study. Within the selected body of literature, 851 instances of ACs were distributed across students ranging…

This review extends on previously reported findings in which students were asked to construct Reaction Coordinate Diagrams (RCDs) de novo. Instead of asking students to construct RCDs, this study explores students' understanding of kinetics and thermodynamics when provided with mechanisms for the Aldol and Claisen condensations. Data was collected…

Hybridization is a bonding model, universally used in organic chemistry, which allows consideration of two-electron localized bonds in organic molecules. Without hybridization, it is almost impossible to describe aspects such as hyperconjugation for the stabilization of carbocations and alkane conformers. Hybridization is often presented in…

Science concept formation has a long history in early childhood educational research. Most of the studies in the field focus on the way children form science concepts as preschoolers. However, less is known about the nature of science concept formation for children under 3 years of age. This study explores how early childhood teachers create the…

Although formulating a broadly accepted definition of scientific literacy may be challenging, it is widely recognized that Nature of Science (NOS) is an essential component of it. There are different ways to define NOS. In some cases, NOS can be conceptualized through a number of general NOS aspects like for instance science's empirical basis or…

Background: Recognizing the relatively few studies that have explored university students' understanding and alternative conceptions in linear and circular motion as well as the relatively few studies that have used 2-dimensional multiple-choice questions (MCQs) in the science education literature, this study set out to contribute to these areas.…

This study aims to investigate the views of pre-service teachers who have taken the "Science Teaching" course in the undergraduate program of classroom teaching about the teaching of science concepts. In this study, the phenomenology study approach, one of the qualitative research designs, was used. The study group of this research…

A major challenge when designing new experiments for the general chemistry laboratory is introducing students to the necessary techniques while keeping the experiment engaging and accessible. This work presents a new multiweek activity designed to introduce students to advanced instrumentation in the form of high-performance liquid chromatography…

Chirality continues to intrigue scientists because of its implications in various scientific areas, including the long-unsolved question of its development and link with the origin of life. Chirality plays a significant role in medicine with the advent of chiral drugs and the consequent importance of asymmetric synthesis. For many undergraduate…

The distribution of pulmonary blood flow is uneven and can be described as a three-zone model, the West zones: zone 1 occurs whenever alveolar pressure exceeds arterial pressure; zone 2 when the arterial pressure is greater than alveolar but the alveolar pressure exceeds the venous pressure; and finally zone 3 when both arterial and venous…

Under the appropriate conditions, oscillatory chemical reactions have the capacity to generate chemical waves and spatial patterns. Among these structures, Turing patterns are a distinct class that, to date, has not been commonly demonstrated in a classroom environment. We present here a novel, practical procedure for the demonstration of Turing…

This Family and Practitioner Brief discusses the challenge in translating complex scientific words with abstract concepts from spoken/written language to American Sign Language (ASL).

The Kigali Amendment introduced a new family of chemical compounds, which do not contribute to stratospheric ozone depletion but present a high global warming potential, under the watch of the Montreal Protocol in 2016. Earlier this year, a press note from the World Meteorological Organization entitled "Ozone layer recovery is on track,…

Microfluidic-based ultramicroscale chemistry experiments involve the manipulation and consumption of reagents on a microliter or submicroliter scale in a microfluidic device. This article presents the pedagogical functions of microfluidic systems, including green chemistry education, stimulation of students' interest in learning about chemistry,…
