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…

Analytical chemistry is one of the chemical materials that is considered difficult by students. The application of multi-representational proximity in delivering analytical chemistry material can make it easier for students to understand the material. The purpose of research and development is to produce Instagram- and TikTok-based learning media…

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.…

Many researchers have suggested that incorporating history and philosophy of science in the science curriculum can be helpful for students' understanding of scientific concepts and effective for developing their scientific thinking. Recently, in this context, there have been studies on historical controversies which show that history of science…

The oscillating atmospheric CO[subscript 2] concentrations at Mauna Loa, on the island of Hawaii, Hawaii, United States of America, are Fourier transformed in order to extract the period of oscillations. Also well-known as the Keeling curve, CO[subscript 2] concentrations (in time series) at Mauna Loa oscillate in direct association with seasonal…

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 push for project-based learning (PBL) has been at the forefront of education for the last decade. Exposure to projects even in the lower grade levels helps students learn foundational skills that will strengthen the collaborative and leadership skills that will assist them as they get older. The result of a typical PBL project requires…

Contrary to the situation at primary, middle, and secondary school levels, university science courses provide students with very few opportunities to reflect upon the nature of science (NOS). The first goal of this study was to provide evidence that the co-construction of evolutionary trees, an important component of university biology education,…

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.

This paper discusses the use of educational equipment and materials can be used by biology teachers. Science Education has an important role in raising individuals who can adapt to developing world with the 21st century skills. Within the scope of science education, biology covers information that individuals can make use of in their daily lives.…

Entropy is a concept with an extreme controversy which many scientists have been trying to explain. Some of the approaches employed in its definition contradict each other, which made it extremely difficult for high school and college students to understand. Boltzmann was the first person who brought a statistical explanation to entropy and…

The term "Classroom Proxemics" refers to how teachers and students use classroom space, and the impact of this and the spatial design on learning and teaching. This study addresses the divide between, on the one hand, substantial work on proxemics based on classroom observations and, on the other hand, emerging work to design automated…
