Topics featured in this issue include: innovative curriculum; exploring kinetics; engaging organic chemistry activities; molecular structure and symmetry; polymer chemistry; technology-based instruction; synthesis laboratories; undergraduate research experiences; from the archives: bath bombs and cosmetics chemistry.
While POGILⓇ Activities are designed to be completed synchronously in a collaborative team setting with the teacher present as the facilitator, there are ways to utilize the activities in an asynchronous online setting.
No one really knows how to immediately transform an in person class to a distance learning environment. We struggle to provide an equitable education, whatever that looks like, for all our students and make accommodations for differences in learning abilities, home lives, internet access, in addition to mental and physical health.
With the current global COVID-19 pandemic, there has been much discussion of “flattening the curve” by social distancing. These ideas can be demonstrated chemically, for example, by the iron-catalyzed decomposition of hydrogen peroxide to produce an oxygen gas foam. Decreased hydrogen peroxide concentrations, representing decreased human population concentrations from social distancing, produce oxygen gas foam, representing cases of illness, at a slower rate. A similar demonstration can be achieved using the popular Diet Coke and Mentos experiment. These simple experiments are best used as stand-alone demonstrations.

Have you heard that TERC, a nonprofit, has launched a STEM Teacher Leadership Network funded by the National Science Foundation? The online community is for aspiring or current teacher leaders, researchers and administration to improve STEM education, effect policy and discuss the changes to the future of STEM education in a collaborative online collegial network.
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.
