Although integrating the history of science (HOS) into teaching has long been recommended in science education research, studies have revealed conflicting results on its effectiveness. These are mainly due to the need for more studies in this context. Therefore, this research aimed to explore the impact of HOS teaching on science process skills,…

A balanced interrelation between theory and practice is still often missing out in many (language) teacher education programs (Esteve, 2018; Lantolf & Esteve, 2019). Hence the need to critically analyze teacher educators' professional practice and rethink it. This paper presents a deep reflection upon the difficulties and the possibilities of…

This paper consists of a systematic review of the literature on ChatGPT's application in science education, drawing from studies conducted between January and September 2023, examining the current landscape, challenges, and implications of integrating ChatGPT into science classrooms. Analysis revealed a predominant emphasis on physics and…

Upper-division undergraduate students are introduced to polymer processing using material extrusion fused filament fabrication 3D printing to make poly(lactic acid) (PLA) mechanical testing specimens. Computer aided design and slicing software packages are used to demonstrate the process of preparing 3D computer models for printing. Following the…

This generic qualitative study examined how mid-to-late career experts in the U.S. space exploration sector transfer tacit knowledge to novices, with a particular focus on fostering employee engagement. Semi-structured interviews were conducted with ten industry experts from various sectors within space exploration. Thematic analysis identified…

Teachers are increasingly expected to incorporate Project-based learning (PBL) pedagogy to teach science. While teachers' definitions and challenges in the use of PBL are widely studied, very few studies focus on the development of a teacher's knowledge of the use of PBL over multiple projects. The current research is an in-depth case study aimed…

The Curie temperature, also called the Curie point, is the temperature at which magnetic material undergoes a phase transition from ferromagnetic to paramagnetic properties. The characteristics of permanent magnets appear below the Curie temperature--below 400 °C (673 K) for commercial ferromagnetic materials such as ferrite or neodymium. In…

The American Association for the Advancement of Science (AAAS) has outlined four themes that define science literacy; these are systems, models, constancy and change, and scale. More recently, the National Research Council has released the framework for K-12 science education that includes "Scale, Proportion, and Quantity". Scale…

This paper presents a new way to demonstrate the principle behind mirages in air in the lab. The setup is simple and includes a modified laser illuminator that allows direct comparison between the deflected light rays and their straight path.

We have created and validated a conceptual framework for the core physiology concept of "cell membrane." The conceptual framework is composed of 27 items arranged in a hierarchy that is, in some instances, four levels deep. We have validated it with input from faculty who teach at a wide variety of institutional types. All items making…

In this laboratory experiment, students apply a mass-based approach to determine the Henry's law constant for CO[subscript 2] using a small bottle of a diet carbonated beverage. The calculations are challenging; therefore, team-based learning is encouraged. Our students reported values of 0.033 ± 0.003 mol/(L[middle dot]atm) at room temperature…

One theme that both the American Association for the Advancement of Science (AAAS) and the National Research Council (NRC) agree pervades any science course (and specifically chemistry) is scale. Despite the fact that scale concepts and skills are at the core of a student's scientific literacy, scale or the skills related to understanding quantity…

Background: This article argues that the emergence of scientific reasoning in the preschool years could be augmented by caregivers and preschool teachers through nurturing 'Habits of Mind' (HOM) and 'Habits of Body' (HOB) of young children. This type of mind--material-- body integration is proposed from an epistemological position that comprises a…

A mechanical model of light propagation helps to show that optical refraction is related to the speed of light and how it changes from one medium to another. A tricycle toy robot is used to realize the model. Left and right wheels independently change their speed (high or low) in response to the local color (white or black, respectively) of the…

Whilst many science educators, it is reported, associate knowledge with justified true belief (JTB), epistemologists have observed that the JTB model is an incomplete account of knowledge. Moreover, researchers from several fields have argued that developing scientific expertise involves not only the acquisition of knowledge that can be expressed…
