Practical learning methodologies have become the need of the hour in the education sector, in particular in engineering education, to achieve technical competencies and skills. Advancements in web-based learning strategies have evolved over the years, and technology has played a major role in creating e-learning resources, among which remote labs…

The theory of Expansive learning and the change laboratory (CL) methodology has been developed and applied in many studies on workplace learning and educational change. There are fewer studies made on small-scale interventions, exploring the longitudinal development of expansive learning in an educational change effort. This article examines a CL…

Teaching chemistry without access to a traditional laboratory space is an ongoing challenge that has become especially relevant because of the SARS-CoV-2 pandemic. While several remote learning options exist for covering general chemistry concepts (including kitchen-based experiments, online modules, and virtual reality), few options provide…

A laboratory experiment was performed using tetra-n-butylammonium bromide (TBAB) ionic semiclathrate hydrate, a crystalline compound. Ionic semiclathrate hydrates have unique properties, and hence, novel technologies utilizing the ionic semiclathrate hydrates have been proposed to date. Thus, students could learn fundamentals of functional…

We are living in the Big Data era, and yet we may have serious troubles when dealing with a handful of kinetic data if we are not properly instructed. The aim of this paper, related to enzyme kinetics, is to illustrate how to determine the K[subscript m] and V[subscript max] of a michaelian enzyme avoiding the pitfalls in which we often fall. To…

A laboratory experiment was developed to introduce undergraduate chemistry students to the chemical characterization of agroindustrial waste extracts by gas chromatography-mass spectrometry (GC--MS). The students prepared hexane and dichloromethane extracts from black pepper ("Piper nigrum" L.) waste. GC--MS analysis revealed the…

Virtual labs have proven to be very versatile and valuable for providing realistic experience for students in STE (Science, Technology, and Engineering) fields. As we progress from delivery of instructional material from classroom to the Internet, there is need to develop laboratory exercises to supplement the theoretical lessons. A Web-based…

Academic work in universities is in flux with staff increasingly being confronted with multiple and conflicting roles, often leading to academics experiencing feelings of fragmentation and despair. Though much has been written about the changing nature of academic work and its effects on the academic workforce, there has been less exploration of…

A Foldscope is an ultra-affordable paper microscope with a magnification up to 2000X and 2 micron resolution. It is economic, durable and easy to handle tool for scientific studies. Many govt. schools of Kamrup district, Assam found it difficult to use microscope in their regular practical classes for its complexity and high cost. For…

This experimental lab set is for students taking college chemistry courses. It includes four laboratory works and completely illustrates the important parts of chemical kinetics, namely the determination of the rate constant and the determination of the factors influencing its value. They can be used in a laboratory set for a physical chemistry…

Although many laboratory experiments are available to illustrate spectrophotometric or fluorometric methods, few of them introduce the use of luminometry to students. Bioluminescence, a subtype of chemiluminescence, is produced when an enzyme-catalyzed chemical reaction gives rise to light emission. Despite the advantages of bioluminescent…

A laboratory exercise for undergraduate advanced students of enzymology and biocatalysis is presented. Since enzyme assays can be quenched or continuous, this experiment compares the performance of two quenching agents for lactase, in a continuous setup. Enzymatic activity of [beta]-galactosidase ("Aspergillus oryzae") was determined…

Using a qualitative approach based on grounded theory, this study explored the best practices of educational technology implementation in 2-year community college writing centers through a series of interviews with 13 separate 2-year community college writing center administrators. This study utilized Vygotsky's (1978) sociocultural development…

The main goal for this work was to provide information as to the possibilities of creating an online or hybrid option for an upper-level biomechanics laboratory that is in keeping with course goals. Conversion of the laboratory modules for online use was described with detailed setup and learning goals. The lecture portions and most labs could be…

The creation and evaluation of known evolutionary histories and the implementation of student investigatory experiences on evolution are difficult endeavors that have only recently been feasible. The research presented in this dissertation is related in their shared use of digital evolution with Avidians as a model study system, both to conduct…
