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.
The Devil's Milkshake is a simple, yet interesting chemistry experiment that fits well as a Halloween demo.
Standards based grading (SBG) is a method of assessment that is gaining in popularity. There is ample research to suggest that students who participate in SBG do just as well or even better than those students in traditional classrooms
Want to heat up a department meeting? Just propose that all courses have an on-line option and watch as some colleagues have strong opinions about it- be it on one side or the other. What overlooked component can be distilled from a normal in-person course into an online that could have a significant impact? Perhaps the face-to-face “live” interaction.
The flipped-classroom approach to education is undoubtedly popular, with consistent growth in the number of related books, conference sessions, and educator network memberships. Although active-learning may not be any more beneficial in a flipped classroom compared to a traditional classroom, it is clear that a flipped class can increase the frequency of active-learning opportunities.
Kristen Drury shares how she covers the new AP Chemistry Course and Exam Description Learning Objectives associated with atomic structure.
Once one knows about Critical Pedagogy (with respect to Critical Thinking, as was covered in the previous blog), how is that knowledge used? Can strategies be implemented that embrace Critical Pedagogy while not sacrificing content coverage? What are some ways to build criticality in students while maintaining expected requirements for classroom rigor?
The first unit in my sequence for AP Chemistry covers stoichiometry and reactions. The new AP Chemistry Course and Exam Description has identified Learning Objectives which need to be taught and practiced to ensure students perform well on the AP Chemistry Exam. I will identify and describe activities I use to teach students some of the Learning Objectives that I tie into this unit.
