Before reading this essay, go to your kitchen and find a bottle of Italian salad dressing. Get one that has been sitting still for a while at a fixed temperature--that is, one in thermal equilibrium. You will find an oil-rich layer at the top of the bottle and a vinegar-rich layer at the bottom (see Fig. 1). But think for a moment before spreading…

A popular physics legend holds that scissors can cut paper with a speed faster than light. Here this counter-intuitive myth is investigated theoretically using four simple examples of scissors. For simplicity, all cases will involve a static lower scissors blade that remains horizontal just under the paper. In the first case, the upper blade will…

Purpose: Learning, unlearning and relearning (LUR) has been preached as a panacea to organizations. Whereas, research on learning and unlearning has grown exponentially, relearning is still considered as an obscure concept. This paper aims to provide a new insight on organizational relearning and highlight its linkages with organizational…

For 26 years, it has been assumed by some that the thermodynamics of open-system biochemical reactions must be executed by performing Legendre transformations on the terms involving the species whose concentrations are being held fixed. In contrast, standard nontransformed thermodynamics applies to chemical processes. However, it has recently been…

The various radiation types that make up the electromagnetic (EM) spectrum are ubiquitous and highly significant in modern society. Detection of visible light by the eye facilitates sight, radio waves and microwaves are used in communication technologies, x-rays are used in medical imaging, and gamma rays are frequently employed in medical…

This discussion paper makes the case that the term counter-argument should be replaced with the term "alternative point of view," as the counter-argument, in an essay, implies that it is the opposite of the argument put forth by the writer, and, in fact, it isn't. It, also, looks at the root of the word counter and how that word is often…

As some misconceptions remain persistent, comforting and highly resistant to change, it is imperative to use methods and strategies that are centred around students' abilities, interests and needs to address those misconceptions. This study investigates the appropriateness of using 'concept cartoons' to address misconceptions held by forty grade 9…

Humanities majors are used to answering the question, "So, what are you going to do with that degree?" The common misconception is that students in humanities programs don't learn any useful skills for the real world. In "Major Trade-Offs," sociologist Corey Moss-Pech argues that not only do humanities majors learn real-world…

The study investigated the issue of sexual harassment myths among the students of higher institutions of learning in Southeast Nigeria region, focusing on the male and female undergraduates from these institutions as the study population. While the study was guided by Structuration Theory, survey design with questionnaire instrument was applied to…

Concurrency is a complex to learn topic that is becoming more and more relevant, such that many undergraduate Computer Science curricula are introducing it in introductory programming courses. This paper investigates the combined use of Sonic Pi and Team-Based Learning to mitigate the difficulties in early exposure to concurrency. Sonic Pi, a…

Teachers require support in developing the pedagogical skill of interpreting students' mathematical thinking and providing effective feedback that promotes learning. However, there is a lack of research assessing the quality of feedback based on teacher noticing in mathematics classes. This study analysed 20 preservice teachers' (PSTs) feedback…

Science, Technology, Engineering, and Technology (STEM) fields face challenges with underrepresented minority (URM) student achievement and retention. White students earned 59% of bachelor's degrees in science and engineering, while LatinX and African American students earned 16% and 9% respectively (National Center for Science and Engineering…

The research is motivated by the demands for the readiness of elementary school teachers and students to face the Merdeka Curriculum, one of which is the demand for HOTS-based learning. The implementation of HOTS-based learning requires an evaluation using HOTS-based test questions as well. The objectives are, (1) to analyze and examine the…

Background: The COVID-19 pandemic and the shift to digital learning materials have dramatically reduced the use of paper-based textbooks in higher education. In the field of engineering, students need a comprehensive understanding of mathematical concepts, which can be achieved through the use of e-textbooks. These digital learning materials can…

Children's books play a central role in today's classrooms. Educators can use children's literature to promote children's social and cultural understandings and critical thinking skills. This is particularly important when extending children's knowledge and understandings of themselves, their identity and those who may differ culturally, socially…
