Engineering and technology educators continually strive for realistic, hands-on laboratory exercises to enhance their students' learning. This research describes the redesign of an undergraduate introductory computer networking course to include new weekly virtual laboratory assignments that culminate in a 'real world' final project of configuring…

High-performance liquid chromatography is one of the primary techniques covered in the undergraduate analytical chemistry curriculum. This technology report describes the use of a portable capillary-scale instrument that can provide similar performance to a benchtop instrument but generates less solvent waste and enables operation in nonlaboratory…

The COVID-19 pandemic is promoting online education. In this concern, not only online teaching of wet laboratory practices is being challenging, but also online teaching of practices in bioinformatics. Here, I discuss the problematic of online teaching practices in bioinformatics and provide fundamental guidelines, especially oriented for beginner…

Oxygen reduction reaction (ORR),as a multielectron electrode reaction, is an important electrochemical reaction in the field of electrochemical energy storage systems. Herein, a new advanced electrochemical laboratory experiment is designed for undergraduates to master the preparation of oxygen reduction catalytic electrode. Students can use…

Recent research has shown a great interest in supporting self-regulated learning (SRL) strategies in online learning. However, there is hardly any study that has investigated how students' self-regulation of behavior could be promoted in online environments for programming learning and assessment, despite the proliferation of automated programming…

Youth often fail to see themselves in the role of a scientist or engineer and they may lack the confidence to believe they can be successful in STEM courses and careers. This study investigated students wearing lab coats as one strategy to build science academic self-concept and self-efficacy in science. Teachers in four elementary schools had…

The reigning orthodoxy in writing centres has been to avoid directive approaches and embrace non-directive approaches to tutoring. Although this 'myth has been debunked by various writing centre scholars since the late 1990s, many guidebooks on tutoring still adhere to it. We believe that theory-led empirical research on tutor approaches and…

Amidst the COVID-19 pandemic, many colleges shifted to online learning, creating a need for teaching materials that could be deployed in the online setting. A pair of virtual laboratory exercises with a COVID-19 theme were created for first year Biology majors to introduce students to the topics of polymerase chain reaction and gel…

There have been multiple calls to incorporate the teaching of scientific practices within science laboratory courses over the past decade. To accomplish this goal, changes must be made to the curriculum standards, instructional programs, and assessment-evaluation systems used in laboratory courses. One instructional program that can used in a…

In this teaching laboratory, the students are directed in an exercise that involves designing and performing an experiment to determine estrogen's role in regulating delayed implantation (diapause) in female rats. To encourage active participation by the students, a discussion question is provided before the laboratory exercise in which each…

Magnetic iron oxide nanoparticles were synthesized and stabilized using ammonium cations or poly(vinyl alcohol) to produce amazing materials such as safer aqueous ferrofluids, ferrogels, ferromagnetic inks, plastics, and nanopowders illustrating how versatile materials can be produced just by simple modifications. The synthesis is fast, reliable,…

In this work, the first experiment ever done to determine the age of the Earth is revisited. The benefits of its application at primary and secondary school levels are presented and discussed. In particular, emphasis is placed on the advantage of facing students with the challenges that scientists have had to overcome during the past three…

Here we present a new undergraduate laboratory that will introduce the concepts of time-resolved spectroscopy and provide insight into the natural time scales on which chemical dynamics occur through direct measurement. A quantitative treatment of the acquired data will provide a deeper understanding of the role of quantum mechanics and various…

A laboratory experiment in which students recycle silver and platinum selectively from spent screen-printed platinum electrodes is described. The recovered silver in solution is used to show its spontaneous redox reaction with a copper sheet. The recovered platinum is electrodeposited onto a screen-printed carbon electrode to develop a sensor for…

In 1972 Christian B. Anfinsen received the Nobel Prize in Chemistry for "…his work on ribonuclease, especially concerning the connection between the amino acid sequence and the biologically active conformation." The understanding of this principle is crucial for physical biochemistry students, since protein folding studies, bio-computing…
