As emerging technologies reshape both the body and how we represent it, anatomical education stands at a threshold. Virtual dissection tools, AI-generated images, and immersive platforms are redefining how students learn anatomy, while real-world bodies are becoming hybridized through implants, neural interfaces, and bioengineered components. This…

Bounded by the statements of Feynman and Galileo, I describe certain tricks that can be useful for the teaching of physics. In particular, I describe the calculation of the center of mass (centroid) of an arc of circumference and a circular sector. For this purpose, I also use Pappus's theorems. An Appendix is available with Archimedes' method to…

The various aspects of projectile motion have been analyzed many times in this journal. As a sample, over the years, authors have investigated particular details of the path of a projectile and different situations for launching projectiles. Others have written about a nifty way to determine the maximum height of a projectile, finding the range of…

In this paper, we propose a novel method for deriving Russell-Saunders terms of complex atomic systems with an arbitrary number of equivalent electrons in orbitals with a higher azimuthal number. The method can be regarded as an extension of the classic works of Douglas, McDaniel, and Hyde but with several notable improvements, including the…

By organizing an extracurricular seminar, based on the analysis of the intermolecular dispersion action in normal alkanes, a new topological index (named "Intermolecular Interaction Index (IMI)") was proposed to express the intermolecular dispersion force. The IMI has an excellent linear relationship with the boiling point (T[subscript…

One of the greatest challenges in a student's ability to successfully complete reactions in organic chemistry is the ability to differentiate between reactions that have similar structures and proceed through similar reaction mechanisms. Featured in this article is an interleaved reaction review activity called a reaction web. Students are divided…

Biochemistry is becoming increasingly crucial for undergraduates majoring in biology, chemistry, agriculture, and medicine. In recent years, much research has been carried out on promoting this course's teaching outcomes. However, the knowledge structure of undergraduate biochemistry teaching research has yet to be formed. Here, 715 validated…

A laboratory experiment has been designed for teaching laboratories aimed at training students in the basics of spectroscopy in junior and senior level undergraduate chemistry courses. Despite the ubiquity of light-based tools in modern science, students often find it difficult to comprehend light and light-matter interactions. A portable…

The Homeostasis Concept Inventory (HCI) is a validated instrument for measuring students' knowledge of homeostasis. It is comprised of 20 multiple-choice questions covering key components of the previously validated Homeostasis Conceptual Framework (HCF). In this paper, we present the first multi-institutional study of the impact of physiology…

This case study examined how a kindergarten teacher used and adapted three sets of science curricular materials to promote vocabulary development. Analysis of 126 minutes of science instruction across three video-recorded lessons and the curricular materials used focused on target word selection, discussion questions, and use of educative…

Reflective assignments are a powerful tool in undergraduate STEM courses to promote student metacognition and give instructors and researchers a view of that process. We were interested in understanding student challenges in our developmental biology course, so we used reflective assignments to uncover these challenges and also add to our…

Gardening provides children with hands-on, minds-on, and inquiry science learning. This article describes the benefits of gardening, preparations for gardening with preschoolers using children's books, creation of a garden, and planting a garden. It presents ways in which teachers can look deeper for the practices and experiences that meet the…

The UV--vis absorption of cyanine dyes is a common experiment in many physical chemistry teaching laboratories. As part of the analysis, students are often asked to hypothesize why the predicted absorption differs from the measured values and why dyes which are predicted to have the same absorption have measured values which differ from each…

In school chemistry, the oxyhydrogen or "Knallgas" reaction is used to provide evidence of hydrogen gas in the squeaky pop test. However, the test actually indicates the presence of an explosive gas mixture of hydrogen and oxygen (oxyhydrogen gas) rather than pure hydrogen. The sheer observations of an explosive reaction and the…

This research is a systematic literature review study that aims to explore the evidence in publications that report on the types of misconceptions experienced by students in learning chemistry by providing types of students' chemical misconceptions based on levels and obtaining the correct formulation of misconceptions so that they can be used as…
