Microfluidics has attracted widespread interest in the fields of chemicals, materials, pharmaceuticals, biology, etc. Integrating low-cost automation based on open-source hardware/software to improve lab security and reduce time consumption is demanded in microchemical processing. In this work, we developed a "do it yourself"…

Atoms may repel or attract each other, but bound systems get virtually all of the attention in the classroom. To address the imbalance, instructors can explore the basis of repulsion in a few simple systems and highlight the important role played by the Pauli principle. A good example is the first triplet excited state of H[subscript 2] wherein…

This study was aimed at assessing the research trends in the family resemblance approach to the nature of science (FRA-to-NOS). This was accomplished through bibliometric analysis using the R program and a literature review employing the analysis framework. The findings demonstrated that the field of FRA-to-NOS has been experiencing growth, with…

We present a tool, one that is both a stand-alone web-based video game and a Python package, designed for students to explore a particle's wave function on one-dimensional potential surfaces. The tool relies on a basis set formalism and can, therefore, explore any one-dimensional potential surface imaginable. This tool also lets students interact…

Developing students' understanding of the nature of science (NOS) is seen as critical for educating scientifically literate citizens, and has emerged as an important curricular goal internationally. In Norway, a new curriculum reform has recently been implemented, intended to improve the Norwegian education in several ways. The reform aims to…

As introductory chemistry courses expose students to many distinctive properties of matter, it is helpful to systematically evaluate and relate different measures such as mass, moles, and molarity, or specific heat capacity and heat capacity. Intensive and extensive designations help distinguish intrinsic and component properties of a system and…

An application for visualizing the dynamic properties of an equimolar binary mixture of isotropic reactive particles is presented. By introducing a user selectable choice for the activation energy, the application is useful to demonstrate qualitatively that the reaction rate depends on the above choice and on temperature. The application is based…

The study consisted of three articles. Article one aimed to determine if there were any significant difference in science graduate students' (SGSs') conceptions of the "consensus tenets" of the nature of science (NOS) with respect to demographic factors -- the SGSs' academic and research characteristics. The participants were SGSs from…

Rheology is an enormously far-reaching branch of physics (or physical chemistry) and has a number of different guises. Rheological descriptions define fluids, semi-solids and conventional solids, and the application of this science defines the performance and utility of materials and substances as diverse as foods (such as yogurt and marmalade),…

The 1969 version of "The Italian Job" is used as context for teaching turning forces and introducing or enhancing the understanding of equilibrium and Newton's Third Law of Motion. A Harrington Legionnaire coach is used as the getaway vehicle for a gold heist and the film ends on a genuine cliffhanger, with the rear half of the coach…

Science teacher's self-efficacy has been at the center of many investigations on students' achievement in science, teacher burnout, and teacher performance. While overly studied, this construct has not been examined with scientific literacy in depth. Thus, this study aims to identify the influence of science teacher's scientific literacy on their…

In this study, we examined the teaching emphasis of the history of science (HOS) in science lesson plans. The examination was based on a five-dimensional framework, which comprises conceptual, procedural, epistemological, affectional, and social dimensions. Content analysis was employed as the research methodology, targeting 71 copies of science…

Epistemology plays an important role in detecting learning difficulties in a given field of knowledge and in directing strategies to eliminate them. This quantitative study aimed to get to know the perceptions of 624 students, related to the nature of science and science teaching and learning. The cross-sectional survey, based on the Inventory of…

In this study, diagnostic worksheets adopted from the Royal Society of Chemistry and microscale chemistry activities were employed to investigate teacher trainees' understanding of chemical compounds. The framework for the study was hinged on the constructivist theory. Participants in this study were 36 1st-year undergraduate teacher trainees of…

This article presents a qualitative study, descriptive-interpretive in profile, of the effectiveness in learning about the nature of science (NOS) of an activity relating to the historical controversy between Pasteur and Liebig on fermentation. The activity was implemented during a course for pre-service secondary science teachers (PSSTs)…
