30 Praxes from 30 Years of Teaching

30 Praxes from 30 Years of Teaching brings together classroom practices I have developed, adapted, and refined throughout my career as a science educator. Each Praxis shares the thinking behind the practice, how I use it in my classroom, and materials teachers can adapt for their students.

Students learn about the people behind scientific discoveries and introduce themselves to classmates through a Scientist Mingle.


Students consider how their identities, experiences, families, and communities shape how they see and participate in science.

Students build confidence in the laboratory through safety, classroom orientation, and practice using scientific tools and techniques.

Students use the Science Writing Heuristic to plan investigations, make sense of evidence, and develop scientific explanations.

Students research a science-related issue and create a newsletter to communicate what they learn to others.

Students use Photovoice to document their communities, examine science-related issues, and share what their photographs reveal.
