Instruction in quantum mechanics is becoming increasingly important as the field is not only a key part of modern physics research but is also important for emerging technologies. However, many students regard quantum mechanics as a particularly challenging subject, in part because it is considered very mathematical and abstract. One potential way…

Background: With the rapid proliferation of online education, it is incumbent upon teachers to find ways to provide online students with science laboratory experiences. Existing research on online labs focuses heavily on computer-supported inquiry learning environments, such as virtual laboratories and remote laboratories. There are limited…

In analytical chemistry, discussing different method sand techniques of analysis is essential to promote critical thinking and reasoning. Analytical courses in the chemist, pharmacist, and biochemist curricula represent the opportunity to study concepts such as experimental design, sampling, development, and optimization of protocols, data…

This case study investigated the conceptual understanding of the Simple Pendulum topic amongst physics student-teachers using online experiments. A pre-experimental design was utilised, employing a one-group pretest-posttest approach with 20 student-teachers. The research instruments included a highspeed video activity conducted within Online…

There is a growing need for chemistry students to be able to handle and manipulate large datasets and analyze them in an efficient and accessible way. This creates the need to develop course materials that introduce these topics early in the undergraduate curriculum. To address this growing need, this activity introduced RStudio to students…

Every year, 4 million people die from upper respiratory infections. Mask-wearing is crucial in preventing the spread of pathogen-containing droplets, which is the primary cause of these infections. However, most experiments for evaluating mask efficacy are either expensive and complex or inaccurate. In this work, a novel, low-cost, and…

The aim of this study was to determine the effect of Mobile AR (MAR) supported Flipped Learning Model (FLM) applications on the academic achievement of first year undergraduate students in General Chemistry Laboratory course and to investigate the students' views on MAR supported FLM. In the study carried out with a quasi-experimental design with…

Fluorescence experiments hold great potential to develop and deepen student understanding of fundamental chemical concepts because the phenomenon is engaging and also illustrates many different chemical concepts and applications, including in quantum mechanics, spectroscopy, kinetics, equilibrium, and stoichiometry, through easily observable…

Science, technology, engineering, and mathematics (STEM) project refers to experiments conducted to address problems, make improvements, or discover new things in those fields that can be tested using the scientific method. This paper describes a long-term STEM project in which pre-service science teachers (PSSTs) have a chance to discover new…

It may be asserted that there is no more effective deterrent to crime than the certainty of detection. Equally true is that there is no surer way to establishing identity than by fingerprints. The detection of fingerprints at the scene of crime is therefore one of the most powerful tools available in casework investigations. However, if the crime…

Teaching alternating currents, ac or sound waves, is incomplete without an introduction to the oscilloscope. An oscilloscope is a tool that graphically displays electrical signals and shows their time dependence. However, due to the pandemic, triggered by the SARS-CoV-2 virus, many students do not have the opportunity to master the use of an…

This study reports on a case study about multimodal work in a primary physics classroom focusing on forces. Previous research reports that students benefit from multimodal work in science classrooms. Yet, few systematic studies have been performed to reveal how students represent their experiences and ideas of science phenomena over time within…

In view of the mounting requirements for courses in nuclear chemistry and radiochemistry, hands-on experience in the separations of radioisotopes is imperative. Three separation techniques commonly used were introduced, coprecipitation, liquid-liquid extraction, and ion-exchange chromatography. Their principles and the associated fundamental…

In chemistry, a eutectic mixture refers to a mixture of two or more components at which the lowest possible freezing point is observed. This phenomenon is covered in a wide range of curricula such as physics, chemistry, chemical engineering, and pharmacy to various depths. Despite the significance of this phenomenon in pharmaceutical compounding…

A multioutcome, discovery-based column (CC) and thin layer chromatography (TLC) experiment has been designed for introductory organic chemistry. Multiple outcomes were established using commercially available two- and three-component analgesic medications based on acetaminophen, acetylsalicylic acid (aspirin), and ibuprofen. A series of 11…
