The Scientific Principles of Reading and Writing Instruction

“In The Scientific Principles of Reading and Writing Instruction, Nathaniel Hansford teaches educators to embrace research over opinion. He breaks up key terms and goes deep into how to interpret and understand research—an area often overwhelming for educators in the classroom. He leaves no stone unturned, diving deeply into phonemic awareness, sound walls, high-frequency words, spelling, handwriting, the real differences between leveled texts and decodables, and so much more. He is also willing to tell uncomfortable truths when the research supports them. This is a brilliant, practical resource that actually helps educators do the work—a literacy masterpiece!”

“The Scientific Principles of Reading and Writing Instruction is a confident but measured guide for any literacy teacher wanting the evidence laid out without shortcuts or obscurity. Hansford pulls the full research picture into view, tackling how reading and writing can be best taught, why the evidence points where it does (including the many gaps), and how to interpret studies with discernment. It’s a rare book that deepens your expertise and sharpens your judgement!”

“It is far too easy for well-intentioned educators to get lost in a single study or misinterpret a complex effect size. In The Scientific Principles of Reading and Writing Instruction, Nathaniel Hansford provides the guardrails, signposts, and running lights we’ve been looking for. He not only provides a map; he equips educators with tools to determine for themselves which paths are truly evidence-based. Drawing on his unique perspective as both teacher and researcher, Hansford writes with a clarity that is as refreshing as it is necessary.”

“I have long been an avid follower of Nathaniel Hansford’s work, watching him move in and out of big, often tricky ideas—and I am consistently impressed by the humility with which he tests his instincts against the evidence. In The Scientific Principles of Reading and Writing Instruction, the author equips educators to understand research, not just receive conclusions, and brings reading and writing into the same instructional frame, arguing that their synergy deserves more attention as a lever for literacy improvement. If you want a readable, practitioner-oriented guide that turns evidence into better day-to-day instruction, this is the book to keep within arm’s reach.”

“Written for teachers by a teacher, The Scientific Principles of Reading and Writing Instruction uses plain language to help teachers think about evidence, separate facts from fads, and judge whether instructional practices are evidence-based. Drawing on meta-analytic data about effective literacy instruction, Hansford gives clear guidance on when and how to teach specific skills and what this means for classroom practice.”
