This exploratory study aims to verify whether the current use of scientific experiments in the Moroccan high-school science curriculum meets students' needs for experimental scientific learning. For that purpose, a sample chapter of the official science textbook was analysed in detail. The analysis was carried out using a didactic model of the…

Heat transfer is a phenomenon well known from everyday life. It is intuitively connected to the properties of materials, that is, to the physics concept of thermal conductivity relevant for cooking or maintaining the constant temperature in rooms, even without being familiar to the underlying physics. However, measurement of thermal conductivity…

Keto-enol tautomerism is a fundamental concept that examines the migration of a proton between two constitutional isomers, the keto and enol tautomer. Many experiments have been proposed to understand the concept behind Meyer's Rule, which states that the keto tautomer is favored as the solvent polarity increases. However, all the experiments have…

This note is about 1000 words in length. We have been taught that this much information is contained in a single picture. But, Fig. 1 is so rich that four separate ideas can be obtained from it! The figure appears in "The Boy's Playbook of Science" by John Henry Pepper. Pepper tells us that this shows an "assistant standing on the…

This chapter illustrates the main warning signals that could help us to detect the flaws of an explanation in physics: internal contradiction (two examples); direct contradiction of a law of physics (one example); indirect contradiction of a law of physics (one example); logical incompleteness of an explanation (three examples); overgeneralization…

The COVID-19 pandemic posed significant challenges for practical teaching within the sciences. While many instructors adopted innovative alternatives to conventional practicals, many relied on digital approaches that did not give students hands-on experience. In this study we evaluate the use of 'at home' practical kits used in first year physics…

Teachers' goals and orientations underlie their instructional decision making and can make the difference between "talking the talk" and "walking the walk" when trying to change lab instruction. Schoenfeld's "Resources, Orientations, and Goals" (ROG) framework was employed to shed light on the challenges involved in a…

To improve student outcomes in four-credit asynchronous online physical geography classes that included a lab component, we employed three different experimental techniques in spring 2022. Fifteen faculty who collectively taught 24 sections of Introduction to Landforms or Weather and Climate modified one element of their course to foster improved…

Institutional ethics review procedures aim -- in principle -- to minimise harm and evaluate risks, providing an important space to consider the safety of participants and researchers. However, literature has questioned the effectiveness of the process, particularly for reviewing 'risky' topics in a risk-averse environment. This article reports the…

Course-based undergraduate research experiences (CUREs) are important for providing undergraduates with authentic research experiences. At Xavier University of Louisiana, a Genetics Laboratory CURE course was developed and implemented. The goals of developing this Genetics CURE laboratory course were: (1) to provide a large number of students the…

Purpose: Although technology is a defining characteristic of distance education, assessment of the applicability of such resources in knowledge dissemination is greatly warranted to ensure effectivity. Hence, the purpose of this study was to assess the viability of a novel tool in teaching practical chemistry online. Design/methodology/approach:…

CRISPR-Cas9 is revolutionizing how we conduct scientific research, treat disease, and develop new crops. The widespread impact of this genome-editing technology makes it critical for undergraduate students to understand and engage with this new tool. In this article, we describe a multi-week lab module that teaches undergraduates how to design…

Contribution: From the moment when universities began to talk about learning environment instead of classes and schools, a summative notion that entails knowledge transfer heralds an important stage of redefining the basic elements of learning. A learning environment requires the transition from learning rounding off toward open learning, without…

The concept of black body is of primary importance in studying the energy transfer of thermal electromagnetic radiation at all wavelengths. Several physical bodies like incandescent lamps, electric heaters, stoves, the sun and the other stars, microwave background radiation, etc., are considered to be black bodies as their radiation spectra fits…

While laboratories have long been associated with introductory physics courses, there is doubt as to whether they positively impact student learning. Holmes and Wieman found that students who elected to take optional laboratories fared no better across a range of metrics than their counterparts who did not participate. In addition, these…
