This research developed learning activities for students to explore and connect the concepts of acid-base titration, equivalence points, pK[subscript a], and molar absorption coefficients. Polyphenolic compounds consisting of p-coumaric acid (CMA), caffeic acid (CFA), and 3,4,5-trihydroxycinnamic acid (3,4,5-THCA) were selected as study models.…

A drug discovery project has been successfully implemented in an advanced undergraduate organic chemistry laboratory. In the laboratory, a five-step synthetic sequence is used to prepare five analogues of 13-phenyl-1-tridecanol. These compounds are key precursors in the synthesis of 2-oxo-14-phenyltetradecanes. This class of compounds, isolated…

A straightforward procedure for the synthesis of (Ph[subscript 3]P)[subscript 3]CuCF[subscript 3], a robust, air-stable trifluoromethylating agent, is reported herein. This preparation can be completed in a single 3 h laboratory session and typically provides ample yields (~79--86%) and high purity (>90%). The target complex is characterized by…

To better prepare undergraduate students for current and future biological challenges, scientists, educators and researchers in the Vision and Change report recommended five core conceptual areas essential for the improvement of biological literacy, one of which is biological systems. Systems are an identified core concept that may help promote…

Learning in asynchronous online environments has gained importance over the last several decades, and educational environment shifts from the COVID-19 pandemic appear to have increased this need. Science educators and students need information about which approaches work in the asynchronous environment where informal feedback tends to be reduced,…

Context-based learning (CBL) environments are widely used in science education to create authentic learning opportunities. Contexts can be authentic through their relation to everyday life, to uncommon scientific phenomena, or to the chemical laboratory. Previous research revealed that students choose contexts that are authentic in different ways…

Society and education are inherently ableist. Disabled people are routinely excluded from education, or have poorer outcomes within educational systems. Improving educational experiences and outcomes for people of color has required educators to design antiracist curricula that explicitly address racial inequality. Here, we explore parallel…

Immunology, a complex and rapidly evolving biological field, serves dual educational goals: training healthcare professionals and immunologists as well as promoting immune literacy among laypeople. This study conducted a scoping review of the literature to explore different aspects of immunology education, examining various contexts, levels, and…

The ubiquity and ease with which microbial cells disperse over space is a key concept in microbiology, especially in microbial ecology. The phenomenon prompted Baas Becking's famous "everything is everywhere" statement that now acts as the null hypothesis in studies that test the dispersal limitation of microbial taxa. Despite covering…

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…

The Survey of Physics Reasoning on Uncertainty Concepts in Experiments (SPRUCE) was designed to measure students' proficiency with measurement uncertainty concepts and practices across ten different assessment objectives to help facilitate the improvement of laboratory instruction focused on this important topic. To ensure the reliability and…

In "Belonging and Identity in STEM Higher Education," leading scholars, teachers, practitioners and students explore belonging and identity in Science, Technology, Engineering and Mathematics (STEM) fields, and how this is impacted by disciplinary changes and the post-pandemic higher education context. In STEM fields, positivist…

Concept inventories are widely used in physics education research, yet numerous studies show that concept inventories measure dramatically different learning gains in different demographic groups. Prior studies show that the performance gaps between demographic groups are already present in their preinstruction responses, suggesting that the…

Most biology undergraduates learn about mutations in multiple classrooms throughout their college career. Understanding personalised genome test results, genome editing controversies, and the appearance of new variants of viruses or antibiotic resistant bacteria all require foundational knowledge about mutations. However, the abstract nature of…

Amidst the disruptions caused by COVID-19, maintaining learner engagement in traditional and online courses has become a significant concern. This study explores the use of embedded video questions in an undergraduate Biology course grounded in the Learning Experience Design (LXD) pedagogical paradigm with the objective to reduce cognitive load…
