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…

This project report highlights a simple yet effective outreach lab benefiting the community partner, specifically the Alameda Point Collaborative (APC) youth program and Saint Mary's College students in a general science course. Building on a partnership focused on reciprocity, a portable lab experiment (Mattson Microscale Gas Chemistry lab) was…

Lab-based learning is an essential part of any undergraduate chemistry curriculum as it incorporates necessary and required hands-on experiential learning. However, in response to the COVID-19 pandemic, many students are learning from home, rendering laboratory instruction a particular challenge. Options for educators include third party virtual…

Virtual laboratories (VL) can provide students with learning experiences simulating practical experiments in a traditional laboratory. Evidence is presented that students believe in the truth of results from the VL as well as those from the traditional laboratory. The underlying reasons for these beliefs are explored, through Russell's description…

Concepts and practices surrounding measurement uncertainty are vital knowledge for physicists and are often emphasized in undergraduate physics laboratory courses. We have previously developed a research-based assessment instrument--the Survey of Physics Reasoning on Uncertainty Concepts in Experiments (SPRUCE)--to examine student proficiency with…

The increasing use of online virtual laboratories (OVLs) in educational institutions as a recent educational technology application necessitates developing a new educational platform for assisting instructors in using such technology in the teaching process without web programming obstacles. The OVLs are online environments that provide students…

For the past decade, the College of Chemistry at UC Berkeley has iteratively redesigned general chemistry laboratory courses to introduce students to green chemistry concepts, while simultaneously using green chemistry as a relevant context to learn chemistry. To investigate the effectiveness of this curriculum we developed approaches to…

With the increase of waste paper, environmental pollution and atmospheric impact have become global problems. The cellulose contained in waste paper has the advantages of being renewable and biodegradable and can be applied to many fields to achieve sustainable development. At present, thermal management materials, as a new type of material, have…

Functional feeding guild classification of aquatic insects is partly based on mouthpart morphology, but the link between mouthpart morphology and ecological feeding roles is often missed by students in the classroom. We implemented a Jigsaw activity in a freshwater biology course to help students connect morphology and ecology. Paired students…

Text-to-speech (TTS) technology is a common accommodation available for students with disabilities. Despite the ubiquitous nature of TTS, this technology has not been explored in laboratory settings for neurodiverse college students. This study explores the adaptability of laboratory accessible TTS technology (originally developed for blind/low…

The 21st century technology has advanced to become an accessible beacon of education. The physical boundaries of the chemistry laboratory have expanded with the use of innovative virtual lab simulations despite disparate results from previous investigations of student performance comparing virtual lab simulations with traditional laboratory…

This study introduces a modernized approach to classical volumetric titrations for the undergraduate chemistry curriculum. Leveraging smartphones and digital top-loading balances, we performed mass-based titrations and determined end points using digital color measurements. Our aim was to make classical wet chemistry more accessible and engaging…

Moving to remote, online learning to meet health guidelines during the COVID-19 pandemic posed a challenge for college science courses due to the interactive nature of laboratories. We developed and implemented a remote/in-person lab partner model where in-person students were paired with remote students in natural science courses during the…

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…

Laboratory-based "practical" classes are an essential component in teaching molecular biology for undergraduate students. Universidad Regional Amazonica Ikiam is a higher education institution located in the Ecuadorian Amazon rainforest, a high biodiversity place, including amphibians. Based on this, we have established a practical…
