The process of meiosis is an essential topic that secondary and postsecondary students struggle with. The important meiosis-related concepts of homology, ploidy, and segregation can be described using the DNA Triangle framework, which connects them to the multidimensional nature of DNA (chromosomal, molecular, and informational levels). We have…

In this article, we put forward a new approach to the teaching of scientific reasoning in biology with the "Next Generation Science Standards" ("NGSS"). We argue that a framework based on the idea of six styles of scientific reasoning provides the best guide for biology teachers to the nature of scientific reasoning in biology…

Students' epistemological beliefs are beliefs centred on one's own learning and knowledge. Such beliefs play a major role in the way one approaches problem solving in physics. The intention of this study is to evaluate such beliefs amongst undergraduate physics students. An analytical tool developed by Hammer has been used as a criterion for…

In the April 2018 issue of "TPT," Joseph Amato presented an analysis of intercontinental ballistic missile (ICBM) trajectories as applied to recent test launches from North Korea. Using properties of their elliptical paths, he derived relationships between launch velocity, elevation angle, and maximum range. However, this approach cannot…

This study aims to investigate the effect of mixed reality applications on students' motivation to learn science. The study further aims to identify students' attitudes toward augmented reality applications and also intends to explore the students' views on mixed reality applications. A total of 42 primary school students participated in the study…

An engaging, simple, and cost-effective laboratory experiment has been implemented at our institution to teach undergraduate chemistry students about cyclic voltammetry and electrochemistry in general. This experiment involves the application of cyclic voltammetry to analyze a sample of acetaminophen (APAP) with the objective of determining the…

The separation of suspensions and immiscible liquids by the laboratory centrifuge is widely used in such fields as chemistry, biology, biochemistry, and clinical medicine. In this paper, an Arduino-based microcentrifuge was fabricated using a computer DVD (digital versatile disc) drive. The hardware part consisted of inexpensive mechanical and…

For many high school students, physics is an abstract subject with complex mathematical statements explaining the world around them. The mathematics can feel intimidating and the introduction of difficult vocabulary, such as "force," "kinetic energy," or "spectroscopy," can give students the impression that physics is…

The aim of the present research was to explore the use of concept maps as an assessment tool. The research question posed was: can concept maps be used to quantitatively assess the learning of a physics topic in an engineering course? This paper describes a new approach to quantifying concept maps. The research was preceded by a pilot project that…

A critical component to disciplinary engagement in science is that of epistemic affect--learning how to "feel" as scientists do when engaged in their work. The emotional responses, feelings, and dispositions that emerge as one participates in the construction of knowledge are part and parcel to the experiences of scientists and, we…

According to Bandura's social cognitive theory, a student's self-efficacy influences his or her academic and career decisions, and his or her performance outcomes; as such, a student's self-efficacy changes with time in response to the student's experiences. Self-efficacy may also vary by academic domain. Differences in STEM self-efficacy have…

A lot of new science has been inspired by common phenomena and even by old traditions practiced in our daily lives. Eventually, after deep exploration, this may engender unexpected new technologies. In this paper, inspired by the wearing of a traditional cloth called a "sarong," by the community in South East Asian countries and others,…

The success of films such as "Avengers: Endgame," "Black Panther," and "Captain Marvel" has established the superhero genre in modern popular culture. Many students will have seen these films, or at the very least they are familiar with a number of the superhero characters. In the physics classroom, content based on…

So many fundamental physics problems involve rigid body rotation that mastery of the subject is essential to many science and engineering undergraduate degrees. Rigid body rotation is typically taught in introductory mechanics courses and while students are generally comfortable with the corresponding kinematic equations, torques and moments of…

A simple apparatus consisting of a plastic syringe coupled with a U-tube has been constructed. This setup is filled with water to trap air in one arm of the U-tube. A change in the volume of the enclosed air causes a change in its pressure that is indicated by the difference in the water levels. Boyle's law is shown by a linear relation between…
