A Modeling Approach to Energy Storage and Transfer

Sat, 05/03/2014 - 15:57 -- Erica Posthuma-Adams

In my previous blog post I described some problems I encountered when beginning my instruction on energy this year.  From the misconceptions fostered by the biology textbooks using the phrase “high-energy phosphate bond” to idea that energy comes in different forms, the Modeling community recognizes the challenges of teaching the energy concept and has developed a way of talking about energy designed to help students construct a consistent and cohesive model.

Socratic Questioning (Whiteboarding Part II)

Avogadro @ NSTA 2013

At NSTA (in beautiful San Antonio, Texas), this past week, I shared activities designed to explore three levels of representation AND provide formative assessment techniques to reveal student misconceptions. All of the activities shared have been featured in the Journal of Chemical Education or have been linked to research articles in JCE as supporting information.
