Hot Topic for Early Spring: Thermogenesis of Eastern Skunk Cabbage
Dean Campbell | Sat, 03/06/2021 - 22:07
The blossoms of eastern skunk cabbage produce heat for a couple of weeks in early spring. This heat, which can be detected using an infrared camera, results from oxidation of carbohydrates. The mechanisms behind this process can be used to introduce energy transduction during classroom discussions of thermochemistry.

Summative Assessment: High Rigor - Low Stress with Katy Dornbos
Deanna Cullen | Fri, 02/26/2021 - 20:45
ChemEd X Talks with Katy Dornbos about how she has transformed the way she is assessing her students - particularly on exams. Her new method of assessing was born from her desire to decrease student stress, minimize her grading time and keep the questions challenging enough to encourage deep thinking. You can watch the edited recording of Katy's Talk here.
ACCT Formative Assessment and Chemical Thinking course
ACCT Admin | Fri, 02/26/2021 - 11:25
The Assessing for Change in Chemical Thinking (ACCT) group has created materials for chemistry teachers nationwide to employ in order to deliver professional development in your schools, districts, and professional organizations. The ten sessions constitute a full course of professional development, which we used to deliver over the course of an entire school year back in Boston. The design of the professional development is based upon three critical frameworks, each of which is a pillar that the PD rests upon. These three pillars are Chemical Thinking, the Formative Assessment Enactment Model and the Teaching Dilemmas. Understanding how these three pillars collectively support the ACCT model of professional development is critical to be able to deliver professional development sessions effectively. More information about each framework is linked above their respective infographics. Session at at glance pages for each of the nine sessions give an overview of what facilitators and participants should expect from each ACCT session.
Why Take Chemistry for Mortuary Science? Part 1
