Is High Cognitive Overload Killing Your Coaching Impact?

The Silent Barrier to Teacher Growth

As coaches, we often focus on the quality of our feedback. But have you ever considered how much information the teachers you support are actually processing?

While we may conduct quick check-ins before a meeting, do we truly account for a teacher's cognitive load as they prepare for new challenges?

Understanding Cognitive Load Theory

What is Cognitive Load Theory?

“Cognitive load refers to the amount of information our working memory can process at any given time. For educational purposes, CLT helps us to avoid overloading learners with more than they can effectively process into schemas for long-term memory storage and future recall.” (Office of Educational Improvement, Medical College of Wisconsin, 2022)

Cognitive Load Theory, first explained by John Sweller in the 1980s, informs instructional design by matching it to the brain's cognitive capacity. Working memory has a limited capacity and requires rehearsal to encode information into long-term memory. This rehearsal occurs both during initial encoding and through retrieval as we build upon existing schemas.

Cognitive Load Theory and Adult Learners

We are failing our teachers (and therefore our students) by choosing to focus on everything. Teachers are learners too. In fact, most teachers identify as “life-long learners” and we expect continual improvement in our profession, apparent with our many initiatives and professional development plans.

Cognitive Load Theory reminds us that learning is most effective when working memory isn't overloaded. While often applied to students, this principle is equally critical for adult learners.

Yet, we often overlook how the adult brain learns. How can we integrate Cognitive Load Theory with Andragogy (Knowles, 1968) to better support educators? Why do both theories matter?

Suggestions for Addressing Cognitive Load with Adults 

There are three suggestions for addressing cognitive load (source); let’s consider these implications for leaders and coaches:

We must also integrate Knowles' Principles of Andragogy to support adult learning effectively (source):

1. Self-Concept - adults are self-directed and independent learners.

2. Experience - adults bring life experiences as a resource for learning.

3. Readiness to Learn - adults seek immediate practical value and application of material.

4. Orientation to Learning - adults approach learning with a problem-based approach.

5. Need to Know/Why - adults want to understand how the information will be used, how it benefits them, and the consequences of not learning it.

6. Intrinsic Motivation - adults are driven by internal factors. 

In the current Science of Reading movement, many schools are juggling new professional learning, curriculum implementation, assessments, and technical systems. This is a significant amount of new information, and in many cases, teachers have not chosen this path nor are they intrinsically motivated to participate.

Cognitive Load Theory and Principles of Andragogy

While we may not be able to change an adult’s self-concept or intrinsic motivation, we CAN consider other principles of andragogy as we engage with adults while considering their cognitive load. In the table below, I’ve added a column to address the adult learner characteristics we can address.

When we ask teachers to manage several initiatives or process too many new ideas simultaneously, we risk cognitive overload. This often results in surface-level implementation, frustration, and fatigue.

Strategies for High Impact Coaching

To protect mental bandwidth and ensure lasting growth, we must prioritize clarity and focus. You can transform your coaching practice by simplifying the target, connecting to prior knowledge, and rehearsing and revisiting. These high impact coaching strategies work together ensure new concepts are manageable and effectively encoded into long-term memory.

Simplify the target: Choose one instructional routine or idea to strengthen before adding more.

Examples from the field:

1. When reviewing student data with a third-grade team, we identified a need for dedicated fluency and decoding time. We started small by introducing one fluency routine. First, teachers learned the steps during planning. Then, I co-taught the initial lessons, modeling the instruction and explaining the "why." For two weeks, the team focused only on this routine. Once mastered, we moved on to a decoding routine for multisyllabic words.

2. A first-grade team implemented a revised eight-step foundational skills framework. To avoid overwhelm, we focused first on mastering the dictation component. I modeled the routine, which we recorded and analyzed as a team. Subsequent coaching sessions focused solely on this step. As confidence grew, pacing and automaticity improved, allowing us to shift focus to increased interleaved practice.

Connect to prior knowledge: Anchor new learning in what teachers already do well.

Examples from the field:

1. A second-grade team was already sharing students for targeted literacy needs. We optimized this by shifting from small-group instruction to a whole-group model using the LETRS© Phonics Lesson plan. Coaching then focused on high-leverage practices: explicit instruction and immediate feedback, using the team's existing resources.

2. In a K-5 professional learning series, we anchored complex new content to the existing literacy curriculum. We deepened teachers' understanding of phonemic awareness, phonics, and fluency by using specific examples from their daily routines, making the learning immediately relevant and actionable.

Rehearse and revisit: Provide opportunities to practice, reflect, and retrieve learning over time.

Examples from the field:

1. The third-grade team refined their decoding routine by using planning time to rehearse lessons, specifically focusing on multisyllabic word division and anticipating student misconceptions. This collaborative practice built teacher confidence, allowing me to gradually reduce coaching support as their instruction became more self-sustaining. 

2. I facilitated a professional learning series for instructional coaches, starting by establishing a shared definition of coaching and coaching cycles. A core insight from the first session was that adopting a "coaching stance" is possible even without the formal title. Coaches were immediately tasked with applying this new understanding to their grade-level planning support. To reinforce learning, subsequent sessions began with a structured check-in: reviewing essential coaching cycle components and sharing examples of how they "coached" their teams. This continuous structure ensured every session deepened their understanding through practice, reflection, and retrieval over time.

Making Growth Meaningful

As Malcolm Knowles noted, adults are self-directed learners seeking relevance. Designing high impact coaching with cognitive load in mind makes learning manageable, meaningful, and memorable. By simplifying the target, we respect the brain's limited working memory. By connecting to prior knowledge, we leverage existing schemas for easier integration. Finally, by rehearsing and revisiting, we support the transition to long-term memory, ensuring professional growth is sustainable and impactful.
