Molecular symmetry plays a central role in chemistry education with regard to predicting chemical properties such as bonding and spectroscopic transitions. Better understanding of the symmetry of molecules requires high visual-spatial thinking ability. Conventional teaching methodologies, with limited teaching aides, fall short in providing a…

Drawing equipotential and electric field lines is an activity commonly found in most second-semester introductory physics courses. Unfortunately, current commercial lab offerings are expensive and do not afford the opportunity for real-time graphical visualization of the trends in voltage in different regions. In this brief article, we describe a…

Recent advancements in biochemical sciences have helped the researchers to explore the molecular logic of life inclusive of its multifarious expressions and explain many facts about the structure and functions of cellular macromolecules. Due to its simple and cost-effective nature, polyacrylamide gel electrophoresis (PAGE) has become the most…

The Curriculum of the Nigeria Certificate in Education (NCE) has implications for the Curriculum of the 9-year Basic Education (BEC) programme in Nigeria. Hence the National Commission for Colleges of Education (NCCE) came up with a vision of producing well motivated teachers with high professional integrity and competence. Both the in-service and…

A laboratory experiment is described in which students determine the concentration and speciation of iron in beer samples using cloud point extraction and absorbance spectroscopy. The basis of determination is the complexation between iron and 2-(5-bromo-2- pyridylazo)-5-diethylaminophenol (5-Br-PADAP) as a colorimetric reagent in an aqueous…

The convenient synthesis of dihydroberberine by the reduction of berberine is described as an experiment for an upper-division undergraduate organic chemistry laboratory course. Students obtained up to 74% yield of the desired pure product without the use of chromatographic techniques. The antimicrobial activities of both compounds against…

There is consensus in the literature that peer learning is beneficial for student content learning as well as affective response to courses. Peer learning methods are used frequently in large science and math courses and often show positive outcomes from all participants. Peer learning programs in undergraduate science education rarely distinguish…

An experimental procedure is presented that was developed by fifth-year chemical engineering and industrial chemistry undergraduates at the Federal University of Rio de Janeiro doing the discipline on Experimental Organic Technology. The aim of this study was to apply the solvatochromic effect of the dye Nile Blue chloride to the characterization…

This study explores the effect of video-based instruction on the safety rules in the chemistry laboratory on student achievement. The sample for the study comprised 61 ninth grade students enrolled in two different classes at a public high school. The students in the class designated as the experimental group (N = 32) were given video-based…

Suspended on-site instruction during the COVID-19 created an exceptional challenge for teaching hands-on laboratory classes. We designed an online laboratory activity using computational biology techniques to overcome this issue. This set of online exercises introduces bioinformatics skills into existing curricula in the form of guided tutorials…

Students' epistemologies of experimental physics refer to how they understand the role of experimentation as well as the experimental operation and design and communication of results in physics. This research aimed to find whether students in inquiry-based physics laboratory activities show more expert-like epistemologies of experimental physics…

The aim of this experimental study was to compare the attitudes of prospective Science teachers towards Chemistry Laboratory and Chemistry Lesson delivered via inquiry-based instruction method in real and virtual laboratories. The study was conducted in 2013-2014 academic year and adopted Mixed Methods design based on both quantitative and…

This article describes a ten week long laboratory exercise designed for undergraduate students aimed at enhancing their understanding of physiological and biochemical responses of plants under dehydration stress. Hypothesis was built around previous reports which suggested that exogenous application of certain elicitors leads to transient…

The current study investigates the differences in students' explanations of friction concepts after the use of the visuohaptic simulation with two different of sequenced approaches: enhanced visual first to enhanced visual and haptic feedback second (V [right arrow] V + H), and haptic enhanced first to enhanced visual and haptic feedback second (H…

A comparison of the experiences of both organic and analytical lab faculty during the COVID-19 pandemic distance learning initiative is described here. Faculty of both lab courses experienced four shared challenges in the transition to the online format: (1) experimental implementation; (2) assessments and postlab activities; (3) technological…
