When Fidelity in Math Improvement Turns Into Rigidity & How To Avoid This Costly Mistake

Implementing with fidelity matters—whether it’s adopting a new math resource, embedding a routine like number talks, or structuring PLCs. But fidelity is not the same as rigidity. When we cling too tightly to practices, they can outlive their usefulness and prevent innovation.

In this episode, we draw from research, including Janice Fraser’s concept of making durable decisions, to unpack the balance between fidelity and rigidity in math improvement. We explore how leaders and teachers can commit deeply enough to see results without locking into approaches that may no longer serve students.

We also examine what it means to hold strong beliefs, loosely held—anchoring commitments in evidence-based math practices while staying open to refinement as new learning emerges.

Listeners will learn how to:

• Distinguish between fidelity to outcomes and rigidity in practice.
• Apply research on durable decisions to math routines and systems.
• Use fidelity as a lever for student achievement while leaving space for adaptation.
• Recognize when it’s time to refine, pivot, or let go of a practice.
• Model “strong beliefs, loosely held” in leading math improvement.

Tune in to discover how to implement with fidelity without getting locked into rigidity—so your math improvement efforts remain both focused and adaptable.
