Based on the Reggio Emilia approach to learning, Visible Learners highlights learning through interpreting objects and artifacts, group learning, and documentation to make students' learning evident to teachers. Visible classrooms are committed to five key principles: that learning is purposeful, social, emotional, empowering, and representational. The book includes visual essays, key practices, classroom and examples.

Visible Learners asks that teachers look beyond surface-level to understand who students are, what they come to know, and how they come to know it.
