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...

The flipped classroom of today looks vastly different from its initial form. Originally, class time was primarily used to complete homework assignments; however, more effective active learning practices tend to dominate class time in modern applications of the model. Although the flipped classroom has improved over the years, several challenges persist.

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.

As high school teachers, we know that understanding how measurement works is crucial for lab skills and for understanding significant figures. We think measurement should be an easy topic for students to learn; especially because we know that teachers begin working with students in elementary school to teach these skills. However, I, and many other teachers, have spent countless hours teaching and reteaching a seemingly simple skill.

A couple of days ago on Twitter, the ever-lasting debate between lecture and active learning reignited due to some talks at an Educational Research Conference held in Dublin. These talks stated direct guidance (which includes lecture) was superior in terms of student learning due its reduction of students’ cognitive load. The main citation used for this argument was an article by Kirschner, Sweller, and Clark published in 2006. So, let’s dive into what this article says.
