The field of biosensors is a burgeoning area of research and employs a large number of chemistry graduates. The impact of strip tests in detecting coronavirus was palpable during the recent COVID-19 pandemic and will further drive the biosensor industry. Despite their common usage, a coherent introduction to the basics of sensing remains missing…

This undergraduate laboratory experiment is designed for first-year general chemistry students with the goal of introducing the brilliant colors and magnetic properties of transition metal complexes within a bioinorganic/cell biology context. In the first laboratory period, a coordination complex formed from ferric chloride and maltol is…

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.…

Laboratory course activities often focus on "cookbook style," so their activities have not yet integrated with scientific thinking as an essential aspect. In this research, the laboratory experience of microbial analysis techniques was redesigned using alternative inquiry to involve students in isolating and characterising yeast to make…

A biochemistry class was transformed to implement student-centered, active-learning pedagogies to help improve competencies associated with the scientific method. In responding to the COVID-19 pandemic, the course content switched from the biochemistry of nucleic acids to the science of the newly discovered virus, SARS-CoV-2. This provided a…

Digestion is a fundamentally important process for an individual's life. However, the physical process of digestion is hidden inside the body, making it challenging to understand and a particularly difficult topic for students to learn in the classroom. Traditional approaches to teaching body processes include a mixture of textbook teaching and…

Cell migration, a fundamental process in development, wound healing, and immune function, is a common topic in undergraduate cell biology courses. We developed laboratory exercises with an inquiry-based learning (IBL) approach in which cell migration could be examined with the scratch assay, adapted from the primary literature. A narrow scratch…

Background: The goals of laboratory experiences include developing knowledge base, research skills, and scientific communication abilities. Objective: The aim was to assess an inquiry-based laboratory activity using the model organism "Caenorhabditis elegans" in relation to learning goals. Method: Students in a "Biopsychology"…

Metabolomics, the large-scale study of metabolites in biological fluids and tissues, offers the ability to observe metabolic changes in a broad context. Traditionally, nutritional metabolism education has focused on theory using textbooks. The objective of this study was to assess the effectiveness of involving students in a feeding research study…

A course-based undergraduate research experience (CURE) is a teaching approach aimed at developing students' ability to conduct novel research. Although students' perceptions of their learning during CUREs may not reflect actual student learning, such surveys provide a convenient and useful metric for course evaluation. Instructors can use survey…

Contemporary research suggests an urgent need for educators to improve the quality of STEM teaching and learning. We developed a semester-long model curriculum for STEM teaching and learning. The overarching goal of this study was to establish an authentic inquiry approach to advanced laboratory courses that is interdisciplinary, collaborative,…

Helping preservice teachers use hybrid language representations in science is important if they are to become scientifically literate and able to engage in the discourse for understanding scientifiyc issues. Using hybrid language representations based on the framework of computer-supported collaborative learning, the teacher educator applied the…

Although research and new technologies have introduced different ways of observing microorganisms, including scanning and electron microscopy, these methods are expensive and require equipment that is typically not found in a middle school classroom. The transmission-through-dye technique (TTD; Gregg et al., 2010), a new optical microscopy method…

In this laboratory experiment, upper-division undergraduate chemistry and biochemistry majors investigate amide-bond-forming reactions from a green chemistry perspective. Using hydrocinnamic acid and benzylamine as reactants, students perform three types of amide-forming reactions: an acid chloride derivative route; a coupling reagent promoted…

Presented is a guided inquiry activity designed to be conducted with prenursing students using an analogous system to help develop a conceptual understanding of factors impacting enzyme kinetics and the various types of enzyme inhibition. Pre- and postconceptual understanding evaluations and effectiveness of implementation surveys were given to…
