Embedded system course requires the manifestation of acquired knowledge through the transfer of the relevant skill set in a hands on environment to achieve the respective course outcome. Laboratory skills provide the optimum exposure and experiential learning to obtain real time solutions for real time problems. The present embedded system course…

This article explores results from a 3-year model of laboratory instruction, Project Synapse, that synthesized biology, chemistry, and communication curricula for firstyear science majors at a STEMfocused university. Laboratory biology-chemistry integration was featured at natural intersections where disciplines used similar tools, such as…

After the COVID-19 pandemic, there was an increasing demand for remote learning and an expansion in the substitution of traditional practical sessions with lab-based virtual tools. This study aimed to assess the effectiveness of virtual labs in practicing biochemical experiments and to examine the student's feedback regarding this tool. Virtual…

The COVID-19 pandemic has constituted a sudden educational transformation around the world. It has disrupted instructors, including physics educators, forcing them to adjust to remote teaching. The hands-on laboratory, one of the components of physics instruction, has also had to rapidly go online in all branches of this science, including nuclear…

Hands-on experiences in analytical chemistry laboratories are essential to improve students' technical skills on handling analytical glassware and instruments, but the coronavirus pandemic in 2020-2021 disrupted such learning activities. Thus, alternative remote activities are required to supplement practical skills. In this work, a new portable…

In the laboratory, data acquisition systems are important, as they allow us to easily and precisely collect data. In this sense, Arduino emerges as an automatic data acquisition device with great potential, due to its low cost and high versatility. In this work, we describe the development of an experimental apparatus, with automatic data…

In addressing the need for safer and more accessible chemistry lab procedures, this work integrates green chemistry and small-scale chemistry concepts to serve as a laboratory model for both qualitative and quantitative analyses of iron(III). An aqueous extract of Indian gooseberry is utilized as a natural reagent to form a complex with iron(III),…

Witnesses to crime often experience stress during the witnessed event. However, most laboratory studies examining eyewitness memory do not include a stressful encoding event. Participants (N = 129) completed an experimental stress induction procedure--a modified version of the Trier Social Stress Test. We designed three conditions to manipulate…

The COVID-19 pandemic severely affected the medical education worldwide. The infection risk for medical students and healthcare personnel who work with COVID-19 positive cadavers or tissues remains unclear. Moreover, COVID-19 positive cadavers have been rejected by medical schools, adversely impacting the continuum of medical education. Herein,…

Ethanol (EtOH) is among the most consumed drugs in the world. The behavior of humans after ingestion of this drug is characteristic: At low doses it may be excitatory and at higher doses, it may induce depressant/sedative effects. Similar effects are observed in the zebrafish experimental model ("Danio rerio"), which has about 70%…

Institutional assessment in higher education often restricts measurement of learning to outcomes that elide the complexity of learning processes and contexts in favor of data that is tidy and manageable. Moreover, such outcomes are frequently written to express an economic value for the learning to justify the purpose of education as a personal…

Approximations can help to orient the student in an organic chemistry laboratory. There the student needs to develop the solvent systems for the reaction and isolation of organic reactants and products. The adage "like dissolves like" helps in this regard, but this approach is vague and entirely qualitative. More quantitative approaches…

A symmetry activity using student-built models was developed in line with faculty-developed pedagogical goals and a collaborative learning framework. The activity took place in a 3-h laboratory portion of an upper-division inorganic chemistry course. It required students to identify symmetry elements for seven molecules using common 2D…

The helium-plasma (HePI) ionization mass spectrometry method was used to track the formation of reaction products and consumption of reactants by continually monitoring the vapors in the reaction headspace in real time. Two examples of the application procedure are presented here: a nucleophilic acyl substitution reaction and a 1,4-nucleophilic…

An introductory experimental course to teach and assess basic organic synthesis and identification skills has been designed. The first work of this course, which is based on the well-known hydrazone formation reaction of benzaldehydes with Brady's reagent, is presented. The designed experiment has many advantages and perfectly matches the goal of…
