We're excited to share a new publication from TERC’s Gilly Puttick, Debra Bernstein, and Mike Cassidy! Dive into their latest research to see how teachers’ perception of the important role of systems in biology and game design can support students’ systems thinking.

Love this! How a child "stacks" the decks tells us so much about what they understand!
I often institute slightly bespoke rules to improve card games, but my very best one is my special rule for War:
For that game only, my kid can set up the decks (in size, composition, and order) however she chooses.
A tweak that greatly improves the enjoyment of all players

In “more than 60 years as an educator… I’ve learned…from sharing ideas with colleagues, I’ve attended workshops, I’ve attended conferences, I’ve read professional books, but my most important source of honing my teaching skills has been the students I’ve taught.”
