An experimental design by combining hydrogel and ethylenediaminetetraacetic acid disodium salt (EDTA) for visually displaying chemical complexation reactions is developed. The Na[superscript +] ions on the [alpha]-l-guluronic acid (G) unit of the sodium alginate molecule undergo an ion exchange with a divalent cation, so that the G units are…

The COVID-19 pandemic has accelerated the shift from traditional in-person teaching to remote and online learning, necessitating a more adaptable educational platform to serve the diverse needs of students. Transforming hands-on "wet lab" activities into virtual "dry lab" exercises can promote a more accessible and flexible…

With the development of new sequencing and bioinformatics technologies, concepts relating to personal genomics play an increasingly important role in our society. To promote interest and understanding of sequencing and bioinformatics in the high school classroom, we developed and implemented a laboratory-based teaching module called "The…

In this article, we describe a basic practical laboratory designed for fifth-year undergraduate students of Microbiology as part of the Epidemiology course. This practice provides the students with the tools for molecular epidemiological analysis of pathogenic microorganisms using a rapid and simple PCR technique. The aim of this work was to assay…

Implementing enzyme-linked immunosorbent assays (ELISA) in microchannels offers several advantages over its traditional microtiter plate-based format, including a reduced sample volume requirement, shorter incubation period, and greater sensitivity. Moreover, microfluidic ELISA platforms are inexpensive to fabricate and allow integration of…

Despite numerous calls for science education to be driven by authentic investigation, many laboratory experiences continue to consist of disconnected weekly units during which students carry out instructions that lead to some predetermined finding. This study developed and evaluated a pedagogical design for introductory biology labs where students…

Current atom concept teachings haven't reached required levels from the points of both teaching methods and learning attainments. With this purpose in this research atom concept is conveyed to the classroom milieu through observations and experiments related to the atom concept during historical development process starting with the masterpiece…

Research projects conducted by faculty in STEM departments served as the inspiration for a new curriculum of inquiry-based, multiweek laboratory modules in the general chemistry 1 course. The purpose of this curriculum redesign was to improve students' attitudes about chemistry as well as their self-efficacy and skills in performing inquiry…

This paper describes curriculum modules developed for first-year general chemistry laboratory courses that use scientific literature and creative experiment design to build information literacy in a student-centered learning environment. Two curriculum units are discussed: Exploring Scientific Literature and Design Your Own General Chemistry…

This paper describes the development of an aero control experiment apparatus (ACEA) for use in aerospace control practical courses. The ACEA incorporates a systematic multihierarchy learning and teaching method, and was designed to improve aerospace engineering students' understanding of unmanned aerial vehicle (UAV) control systems. It offers a…

The Wellcome Trust is running a national engagement and education initiative inspired by the London 2012 Olympic and Paralympic Games. "In the Zone" involves sending practical science kits to every UK school and college. Here, we discuss the development of the school activities and how the feedback from pilot schools helped to shape the…

In this laboratory module, introductory biochemistry students are exposed to two-dimensional [superscript 1]H-nuclear magnetic resonance of glycerophospholipids (GPLs). Working in groups of three, students enzymatically synthesized and purified a variety of 2-acyl lyso GPLs. The structure of the 2-acyl lyso GPL was verified using [superscript…

A novel S[subscript N]1-S[subscript N]2 studio-based lab module that incorporates inquiry-based learning was designed and implemented. The studio module was taught in a newly renovated lab space designed with an integrated classroom. The students were divided into two groups for the lesson with one group conducting a studio-module lab and the…

Oxford College is a small liberal-arts intensive 2-year undergraduate division of Emory University, where inquiry-based courses are a required part of the general education program. We have developed an authentic research experience for undergraduates that mimics--as much as possible--a real undergraduate research experience. Our program provides…

In delivering chemistry courses by distance, a key challenge is to offer the learner an authentic and meaningful laboratory experience that still provides the rigour required to continue on in science. To satisfy this need, two distance general chemistry laboratory courses appropriate for Bachelor of Science (B.Sc.) students, including chemistry…
