The teaching and learning of quantum physics has recently become a topic of increasing interest in physics education research. In particular, the study of two-state systems is gaining importance as a means of teaching quantum physics at various educational levels. Meanwhile, a number of approaches have been developed that are also suitable for…

This study aimed to examine the effect of three teaching approaches: The traditional teaching method, Teacher based demonstration experiment (TBDE), and the Student hands-on experiment (SHE), on students' conceptual understanding of solutions and titration. The data were collected using a chemistry achievement test (CAT) comprising of 30…

Digital practical work (DPW) has emerged as a highly effective and indispensable component of science education, enhancing and extending traditional laboratory experiences. DPW aims to complement physical laboratory experiments, particularly those that teachers may find challenging to conduct or lack the confidence to perform. In this study, a…

The study investigated the potency of ethnoscience instruction on the critical thinking ability of biology students. The study employed a quasi-experimental research design, with a total of 113 senior secondary school two (the equivalent of grade 11) students from two schools in educational district V of Lagos State, Nigeria. All students in the…

Background: Studies in biology have shown that students perceive variation and evolution to be difficult areas to learn. This has sparked rote learning of variation and evolution concepts and is evidenced in poor performance in tests involving these concepts. Purpose: In light of the significant role of variation and evolution in a human's…

With the rapidly increasing demand for STEM skills, many scientists, mathematicians, engineers, and technology professionals encourage students to pursue STEM careers. However, communicating science to lay audiences is challenging due to complex scientific terminology. This qualitative research aimed to demonstrate how an exemplary scientist, Dr.…

For learners to achieve science literacy and become effective citizens who can make informed judgement on science-related issues in their daily lives, many studies have called for robust understanding of Nature of Science (NOS) among science learners. This study echoed the same sentiment, focusing on an aspect of NOS--the relationship between…

In this study, we investigated whether drawing after learning supports metacognitive monitoring especially when students are supported in their drawing efforts. Therefore, eighty-eight participants were randomly assigned to one of three experimental groups. They were asked to learn from a text comprising five paragraphs about the formation of…

This work uses new materialist perspectives (Barad 2007; Lenz Taguchi 2014; Rautio in "Children's Geographies," 11(4), 394-408, 2013) to examine an exploration of concepts as agents and the question how intra-action of human and non-human bodies lead to the investigation of scientific concepts, relying on an article by de Freitas and…

Although principles and practices of green and sustainable chemistry have been articulated for more than 20 years, they have yet to become systemically infused into the undergraduate chemistry curriculum. The American Chemical Society Green Chemistry Institute (ACS GCI) has convened stakeholders from across the chemistry education community to…

A laboratory experiment is described in which students carry out immobilization of the enzyme invertase via entrapment in alginate (Ca-alginate) and, accordingly, estimate values for kinetic constants and mass transfer coefficients. Immobilization of enzymes, or confinement thereof to a defined space with retention of most catalytic activity, is…

Polymers are ubiquitous and essential to modern society, which is why the American Chemical Society has mandated inclusion of polymer chemistry in the undergraduate curriculum. To meet this requirement, we have chosen to weave a polymeric theme through multiple laboratory courses beginning with organic chemistry, where students use aspartic acid…

A eutectic system is a mixture of two or more substances, displaying a melting temperature lower than its standalone components. The eutectic composition displays the lowest melting temperature of all mixtures. Typically, a eutectic system is used as an example of binary phase diagrams to demonstrate to undergraduate students. Herein, the liquidus…

The research described here examined the sources of knowledge of astronomy of children (age 3-18) in China and New Zealand, together with the development of their awareness of competing sources, ranging from everyday language, childhood literature and folklore to the scientific accounts prevalent in schools. The authors cite examples of the…

Watching over a coffee maker in operation, and designing a simple experiment using it, invokes familiar and unfamiliar physical phenomena and techniques involving calorimetry and heat transfer.
