Peg Tyre examines the solution that finally turned around a school with failing test scores, facing closure: a systematic and hierarchical approach to teaching writing that made no assumptions about what the students knew and didn’t know about language. It debunks the popular assumption that writing skills can be simply “caught not taught” and asserts that all facets of language must be explicitly taught in order for students to truly understand how to write, succeed across subjects, and perform on standardized tests.
