Gel electrophoresis (GE) is the most preferred and adapted technique for the separation and identification of biological molecules like proteins/peptides and nucleic acids from diverse types of organisms. All over the world, researchers, educators, and students aspiring to work in biochemistry and molecular biology disciplines use the…

Both nanopore-based DNA sequencing and CRISPR/Cas-based gene editing represent groundbreaking innovations in molecular biology and genomics, offering unprecedented insights into and tools for working with genetic information. For students, reading, editing, and even writing DNA will be part of their everyday life. We have developed a laboratory…

A simple photometric device was built to measure the kinetics of the title reaction. The device consisted of a green light-emitting diode (centered at 520 nm), a sample vial, a photodiode, and an Arduino microcontroller board. These parts were mounted on a black poly(lactic acid) holder which was manufactured by utilizing three-dimensional…

The diversity of scientific methods has received widespread recognition in recent years. The purpose of this review is to analyze the changes in the representation of laboratory work in Chinese senior high school chemistry textbooks in the past 30 years from the perspective of the diversity of scientific methods. This study was based on Brandon's…

Although most teachers recognize the importance of taking investigative, open-ended approaches to students' learning experiences, implementing them in high school classes can be challenging for teachers. In this work, we analyzed data from multiple sources from a teaching Community of Practice (CoP) to investigate (a) barriers to taking an…

Hands-on learning is a staple in high school science education, as it provides students with a fast-learning curve and a great degree of field competency. However, due to the safety risks associated with high school students in university chemistry laboratory settings, high school students rarely engage in authentic hands-on chemical learning. To…

In order to improve learning efficiency and memory retention in medical teaching, furthering active learning seems to be an effective alternative to classical teaching. One option to make active exploration of the subject matter possible is the use of virtual reality (VR) technology. The authors developed an immersive anatomy atlas which allows…

A new module designed to ease the transition from school to university was devised and implemented at Cardiff University School of Chemistry. Two iterations of the module are described, both of them conducted under restrictions imposed by COVID-19 pandemic regulations. Over a two-week period, students attended 15 different sessions, each designed…

It is difficult for students to learn the concepts of chemical laboratory safety education from actual experiences because the traditional teaching model prohibits students from performing dangerous operations. Therefore, this study develops a novel mixed reality-based chemistry experiment learning system (MRCELS) to allow learners to conduct…

Increasing public concern over the use of animal dissection in education is driving development and testing of alternatives to animal use. Clay modeling has proven successful in achieving comparable or superior learning at postsecondary levels, but it has not yet been tested at secondary levels. This study tested the effectiveness and appeal of…

This study aimed at investigating the effectiveness of using Radioactivity Remote Laboratory Activities (RRLAs) in enhancing Form Four (equivalent to Grade 10) students' understanding of radioactivity and motivation to learn science. For this purpose, in this study, a repeated measures one-way ANOVA design was utilized in which 54 Form Four…

This laboratory experiment, designed for undergraduate nonmajors or advanced high school students, attempts to demystify the technique of spectrophotometry by utilizing a hands-on, real-world approach. Modification of the reaction for the formation of Fe[(bpy)[subscript 3]][subscript 2+] allows students to interact with vitamin C, a compound with…

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…

Three-dimensional visualization of molecular simulations in virtual reality (VR) is an emerging teaching tool in chemical education. This work describes a VR application which can generate a 3D molecular dynamics (MD) simulation from arbitrary molecular structures and renders that MD simulation trajectory on a VR headset in real-time. This system…

An investigation was carried out into laboratory practical skills development and students' specific challenges in transition from laboratory chemistry at Chinese High School (HS) to a fully English style university laboratory course. To the best of our knowledge this is the first study of its type investigating practical laboratory skills for a…
