Young children of colour with disabilities have experienced more exclusionary practices in educational settings. Given the fast-growing number of students of colour across classrooms in the United States, and approximately 1 in 6 students identified with disabilities in public schools, it is important to pay attention to why exclusionary…

Within the eukaryotic cell, the actin cytoskeleton is a crucial structural framework that maintains cellular form, regulates cell movement and division, and facilitates the internal transportation of proteins and organelles. External cues induce alterations in the actin cytoskeleton primarily through the activation of Rho GTPases, which then bind…

In introductory physics laboratory instruction, students often expect to confirm or demonstrate textbook physics concepts. This expectation is largely undesirable: labs that emphasize confirmation of textbook physics concepts are generally unsuccessful at teaching those concepts and even in contexts that do not emphasize confirmation, such…

The formation of chemistry identities among students is closely linked to the norms and practices prevalent in their chemistry learning environments. However, these norms may not be equally accessible or aligned with formal assessment criteria, leading to disparities for students in cultivating a positive chemistry identity. This study…

Human anatomy is a key subject area within undergraduate kinesiology programs. However, literature detailing the course structures, available resources, and teaching approaches used to deliver anatomy education in kinesiology programs is lacking. The present study sought to address this deficit by surveying instructors in Canadian university and…

The purpose of this study was to determine the influence that a novel, industry-situated, Science, Technology, Engineering, and Mathematics (STEM) Learning Laboratory (STEM Lab) experience may have on students' (ages 10-18) perceptions of manufacturing-related careers as well as to identify any challenges/strategies for the implementation of these…

Though zoos and aquariums have become increasingly focused on conservation education, their menageries of unique and diverse learning opportunities have been underused. This practical "NGSS"-aligned guide to field trips at zoos and aquariums is written specifically for science teachers to support broader utilization of zoos and aquariums…

This study aims to investigate the relationship between written and oral reasoning in an undergraduate chemistry laboratory course as part of an argument-based inquiry approach, which is also a generative learning environment, known as the Science Writing Heuristic (SWH). The study employed the data-transformation variant of convergent design of…

Interest affects learning; it also affects students' attitude towards science and career choices. It is therefore urgent to increase students' interest and improve their attitude towards science to face the complex challenges of the future. This study transformed cutting-edge induced pluripotent stem cells (iPSC) research into an informal science…

We developed a gas-phase Fourier Transform InfraRed Scientific Instrument Simulator (FTIR-SIS, https://ftir.rastonlab.org/) in response to the unavailability of one during the COVID-19 pandemic lockdown of 2020. It features an interactive interface that encourages students to explore different components of a typical FTIR, and it allows them to…

Research on student learning in organic chemistry indicates that students tend to focus on surface level features of molecules with less consideration of implicit properties when engaging in mechanistic reasoning. Writing-to-learn (WTL) is one approach for supporting students' mechanistic reasoning. A variation of WTL incorporates peer review and…

Simulation is accepted as an effective method of learning procedural skills. However, the translational outcomes of skills acquired through simulation still warrants investigation. We designed this study to assess if skills laboratory training in addition to bedside learning (intervention group [IG]) would provide better learning results than…

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…

Micellar catalysis has become an important aspect of the chemical industry's effort to "go green". However, this chemistry has yet to be fully explored in educational settings such as second-year organic chemistry laboratories. Reported herein is a discovery-based nucleophilic aromatic substitution experiment that introduces chemistry…

This work combines laboratory quantitative analysis of colored solutions and common devices for digital imaging (digital or web cameras or mobile phones, i.e., smartphones). ColorX software, specially designed for this study, was used for data collection and analysis in order to calculate concentrations of colored solutions from measured RGB…
