I was recently reading the November/December 2024 issue of “Science and Children” a publication of the National Science Teaching Association. 

In this issue, I read the “Editor’s Note” column, written by Elizabeth Barrett-Zahn.  She wrote an article entitled, “Expansive Science Teaching Practices.” 

Expansive learning theory, rooted in activity theory, provides a framework for how learners create new knowledge and practices for novel situations.
