Research cores are centralized, shared resources that provide access to advanced instruments, such as nuclear magnetic resonance (NMR) and cryogenic electron microscopy (cryo-EM), and specialized services to scientific and clinical investigators. Most have been founded to address the urgent research needs of STEM programs, medical schools, and…

The paper highlights the development of a collaborative formative assessment scoring process in a partnership between an urban university and one of the nation's largest districts. We explore collaborative research through the lens of a single formative assessment rubric derived from the Claims, Evidence, and Reasoning Framework (CER, McNeill…

The Department of Physics at EKU [Eastern Kentucky University] with support from the National Science Foundations Course Curriculum and Laboratory Improvement Program has successfully converted our entire introductory physics sequence, both algebra-based and calculus-based courses, to an activity-based format where laboratory activities,…

The theory of constructivism states that learning is non-linear, recursive, continuous, complex and relational--Despite the difficulty of deducing constructivist pedagogy from constructivist theories, there are models and common elements to consider in planning new program. Reflective activities are a common feature of all the programs of…

In this study, I present an analysis of instructor comments on assignments written for upper-division courses in the biological sciences as a window into current practices around teaching science writing to major students. My results demonstrate that, while the overwhelming majority of instructors respond primarily to lower order issues of grammar…

Audrey Sillick's article, first printed in 1988, provides a theory base for Maria Montessori's foundational emphasis on the biological sciences and the sustainability of a living, organic planet Earth as part of the educational process "of becoming more fully human." Ms. Sillick helps link primary-level biology with the special energy…

Determining the gas constant "R" by measuring the properties of hydrogen gas collected in a gas buret is well suited for comparing two approaches to uncertainty analysis using a single data set. The brevity of the experiment permits multiple determinations, allowing for statistical evaluation of the standard uncertainty u[subscript…

In general, laboratory experiments focus on traditional chemical disciplines. While this approach allows students the ability to learn and explore fundamental concepts in a specific area, it does not always encourage students to explore interdisciplinary science. Often little transfer of knowledge from one area to another is observed, as students…

This article describes an approach to general chemistry that involves teaching chemical concepts in the context of two thematic laboratory modules: environmental remediation and the fate of pharmaceuticals in the environment. These modules were designed based on active-learning pedagogies and involve multiple-week projects that dictate what…

This article describes two simple classroom demonstrations that illustrate the principles of scanning probe microscopy (SPM) based on a macroscopic analogy. The analogy features the bumps in an egg carton to represent the atoms on a chemical surface and a probe that can be represented by a dwarf statue (illustrating an origin of the prefix…

Nanotoxicity is an area of intense research, stimulated by increased use of nanoparticles in commercially available products. Herein, using nanotoxicity as a platform, we describe an experiment that emphasizes interdisciplinary science in a collaborative work setting while expanding the traditional realm of chemistry and chemistry research.…

We present a set of exercises designed to be used in a survey astronomy course, an introductory astronomy laboratory course, or in secondary education. The exercises use the great works of Vincent van Gogh but could be easily extended to other works of art. We also include a brief description of our current practices, lectures, and group questions…

A trip to the mall is used as a classroom demonstration to illustrate the fundamentals of separations without the need for chemicals or any chemistry background. Student volunteers are the "mixture", and depending on the shopping list they have been given, they spend varying amounts of time in the "stores" versus moving through…

A recent YouGov poll indicated that almost half of eight to 18-year-olds aspire to a career in science. The latest Association of Colleges enrolment survey indicates a large increase in uptake of science, technology, engineering and mathematics (STEM) at further education (FE) colleges. These reports, along with other findings that suggest an…

An experiment was developed to demonstrate a microfluidic device in the analytical chemistry (instrumental analysis) laboratory. Students made the paper-based microfluidic device with a wax pen and a piece of filter paper and used it to determine the total quantity of amino acids in a green tea leaf extract. The device is low cost, easy-to-make,…
