Ungrading: What is it and why should we use it?

Ungrading has long been associated with the idea of purposefully eliminating or minimizing the use of points or letters to assess student work. The focus of ungrading is to provide extensive feedback to students and then jointly (students and instructors) come to a consensus as to what the grade should be. This post addresses what ungrading is and why do it.

26th BCCE Call for Abstracts

The 26th Biennial Conference on Chemical Education, BCCE 2020, will be held on the campus of Oregon State University, Corvallis, Oregon USA July 18-23, 2020. We invite our chemistry education and science education colleagues at the pre-college level (K-12) and college level to submit abstracts of their work for presentations in the symposia sessions, the general papers sessions, or the poster sessions.

The Chemical Laser Show

Chemistry and lasers can be used to create a demonstration that includes several colors and flashing lights. This demonstration connects to topics in quantum chemistry and phase changes.

Metabolic Marvels of Bear Hibernation- Part 2

The post-Thanksgiving excessive calorie-consumption 'blues' have arrived. How is it possible to eat so much? For a bear, it's easy. Easy as pie. Bears are champion eaters, spending about half the year eating non-stop in preparation for winter's foodless landscape. How can this calorie consumption observation about the bear world be used to teach certain chemistry concepts routinely covered? This post includes discussion and two classroom activities about the following common general chemistry topics/concepts- thermochemistry, unit conversions, and interpretation of numerical data. Enjoy...

Chemical Kinetics with a Smartphone

This experiment in chemical kinetics can be conducted using materials as simple as a smartphone, hydrogen peroxide, sodium carbonate solution, and blue food dye! The experiment is useful when discussing the order of rate laws with respect to reactants.

The Metabolic Marvel of Hibernating Bears

Millions of years of evolution has endowed brown (Ursus arctos) and black (Ursus americanus) bears with the enviable metabolic capacity to starve themselves for a long period of time and still survive. Truly, bears are chemist extraordinaires and their hibernation chemistry overall is arguably without equal in the mammalian world. Let's take an introductory look at what's going on.
