To best prepare students for the real-world research environment, key skills, including experimental design, data analysis, communication of results, and critical thinking, should be key components of undergraduate science courses. Furthermore, the impact of the COVID-19 pandemic on in-person teaching has resulted in a need to develop courses that…

A challenge in the pandemic era is to implement effective but flexible practical teaching for biological sciences courses. Such teaching needs to deliver conceptual, analytical and practical skills training while having the option to rapidly respond to health and safety issues, local regulations, staff and student concerns. In this paper, we…

In light of COVID-19 in spring 2020, we developed a simple and versatile inquiry-based, laboratory-style active learning colorimetry experiment amenable to at-home quantitative analysis. In this experiment, students acquire an external calibration method using aqueous solutions of a self-selected chromophoric analyte from household products using…

Due to the COVID-19 pandemic, education at all levels has temporarily shifted to remote learning, hobbling an integral component of chemistry courses: the laboratory. The chemistry lab is crucial for developing student engagement and learning with hands-on, relevant experiments in a socially dynamic classroom setting. The transition to remote…

The COVID-19 pandemic has forced the Bioinformatics course to switch from on-site teaching to remote learning. This shift has prompted a change in teaching methods and laboratory activities. Students need to have a basic understanding of DNA sequences and how to analyze them using custom scripts. To facilitate learning, we have modified the course…

Laboratory experience is an integral part of the undergraduate curriculum in most engineering courses. When physical learning is not feasible, and when the demand cannot be met through actual hands-on laboratory sessions, as has been during the COVID-19 pandemic, virtual laboratory courses can be considered as an alternative education medium. This…

This article presents the study of Fourier series experimentally, using the "ExpEYES"-17 kit in a different way. This familiar undergraduate experiment has been performed for teaching online laboratory classes when face-to-face classes were not possible, due to the "COVID"-19 pandemic. We chose parabolic and sawtooth waveforms,…

Three days into the academic year, the COVID-19 pandemic abruptly led to emergency remote teaching, ERT, of Chemical Experimentation--a revised alternative to the majors' General Chemistry Laboratory at the University of Costa Rica. The course was reoriented to support students' development of nontechnical experimentation skills and scientific…

The COVID-19 outbreak represented a remarkable challenge in universities and colleges since it forced the transition from a face-to-face model in classrooms and laboratories to a remote, online model using computers, tablets, and cell phones. In Mexico and other Latin American countries, the return to educational activities was a slow-paced…

The efficacy of the various pedagogies that are used in human anatomy laboratories has been extensively debated. Nevertheless, an important question remains relatively unexamined--how the learning experience in the anatomy laboratory impacts students' mastery and application of anatomical knowledge beyond the laboratory setting. In this study, the…

Laboratory classes effectively enhance student understanding and appreciation of course concepts. With course delivery suddenly shifted into the online format due to the COVID-19 pandemic, four laboratory exercises in each of two introductory-level soil science courses were converted into virtual sessions delivered in the form of…

Since the appearance of the COVID-19 pandemic and its subsequent stage, the changes produced in the chemistry teaching process have allowed educators to use a wide range of strategies, methodologies, and tools to promote student learning. To carry out laboratory practices, some strategies reported include the use of simulators and educational…

Colorful transitions of various acid-base indicators have been used to illustrate the concept of chemical equilibria, especially in spectrophotometric determination of the equilibrium constants or pKa values. To accommodate an online laboratory environment necessitated by the COVID-19 pandemic, this work employs color analyses from digital images…

At the beginning of 2020, the COVID-19 pandemic surprised the world, affecting activities that promote attendance, including abruptly impacting the education area. Educational institutions, from preschool to university, were required to adopt alternative teaching methods to continue their activities. Distance learning has been adopted by educators…

The reform documents point out the necessity of teaching the plurality of scientific method (SM) when scientists engage in scientific practices (SPs). The dramatic change in education due to COVID-19 pandemic necessitates examining the outcomes of online education, especially laboratory applications courses, which the students and educators used…
