Episode 072: Using Modeling as a Pedagogy in Chemistry

This week we had a conversation with Erica Posthuma, a current high school chemistry teacher. Erica shared with us some of the practices she has implemented as a “modeler” and how she helps students develop their own understandings from their observations and understandings.

Erica also discussed her journey as a teacher, including how she was affected by the pandemic and how modeling has changed how she approaches chemistry. Erica wraps up this episode discussing some of the avenues she has found to publish as a high school chemistry teacher.
