S04E05 - Dr. Kimberly Nix Berens on Applying the Science of Behaviour and Precision Teaching to Accelerate Learning

Mar 28, 2026

Dr. Kimberly Nix Berens, scientist-practitioner and founder of Fit Learning, applies behaviour science and precision teaching to accelerate learning. She discusses why observable, rate-based fluency matters, how precision teaching and timed practice transform assessment and instruction, and why many popular approaches fall short without fluent foundations. Practical routines like personal bests and sprint timings are highlighted.

ANECDOTE

From Broom Closet Program To Global Fit Learning

Kimberley started Fit Learning from a university after-school program using precision teaching for learners with disabilities.
Over 27 years it grew into ~30 centres worldwide and an online division serving thousands of children.

INSIGHT

Define Learning As Measurable Behaviour

Learning must be defined and measured as observable behaviour, not abstract constructs like 'memory'.
Kimberley contrasts cognitive constructs with behaviour science by using count-per-time (rate) to operationalise retention and guide instruction.

ADVICE

Let The Learner's Data Drive Instruction

Let the learner's measured performance drive instructional decisions rather than opinions or grades.
Use regular, objective data (e.g., rates on a chart) to decide mastery, interventions, or acceleration for each student.

In this episode of the Knowledge for Teachers podcast we explore how to transform classroom outcomes using the science of behaviour. Brendan Lee chats with Dr. Kimberley Nix Berens, a scientist-practitioner and the founder of Fit Learning. Together, they unpack the role of behaviour science in education and why observable, measurable learning matters. You’ll hear why fluency—not just accuracy—is the true indicator of mastery, how precision teaching can transform the way we assess and respond to students, and why many common approaches to instruction fall short of producing lasting outcomes.

Kim also challenges some widely held assumptions, including the limits of discovery learning and the over-reliance on grades as meaningful measures of progress.

If you’re looking for practical, research-informed ways to sharpen your teaching and better support every learner, this episode offers a powerful new lens.

About Kimberly

Kimberly Nix Berens, Ph.D., is the Founder of Fit Learning and CEO of Fit Learning Online. She co-created a powerful system of instruction based in behavior science and the Technology of Teaching, which has transformed the learning abilities of thousands of children worldwide. For more than 20 years, her system of instruction has produced at least one year’s worth of academic growth in only 40 hours of training. Her learning programs effectively target such essential areas as early learning skills, basic classroom readiness, phonemic awareness, reading fluency, comprehension, inferential language, basic and advanced mathematics, logical problem solving, grammar, and expressive writing. From her early beginnings in a broom closet at the University of Nevada – Reno, Dr. Berens has helped grow Fit Learning to an organization with centers located throughout the US, Canada, Europe, and Australia. In her current role as CEO of Fit Learning Online, she focuses on increasing access for learners living in regions without a Fit Learning center. Dr. Berens is a frequent invited speaker and a contributor to many popular press publications such as Thrive Global, 74 Million, and Medium. Her first book, Blind Spots: Why Students Fail and the Science That Can Save Them, was released in October of 2020.
