Learning to Learn Part 1: Two Students, One Lesson

Two children can turn in the same perfect quiz and pay very different prices for it. This is Part 1 of our four-part Learning to Learn series on the developmental steps that make classroom learning feel easy, or exhausting.

Key takeaways

• Grades describe the outcome, not the effort. Effort is often the first sign a visual system is working harder than it should.
• We find it useful to think of learning as built in layers - reflexes settle, the senses organize, the motor systems mature, and classroom visual skills sit on top. That is the framework we work from, not a proven developmental law.
• Vision problems do not cause dyslexia, and vision therapy is not a treatment for it (AAP/AAO/AAPOS/AACO, 2009), though some struggling readers do have treatable focusing or tracking problems (Raghuram et al., 2018).

Two students, one lesson

Imagine a classroom of fifth graders sitting at their desks while their teacher presents a lesson on the solar system. She presents an array of images and bulleted points on the planets’ properties, all while elaborating on the details. Students in the class diligently take notes on the subject matter. Let’s look at two students in the class.

Student A

This student sits at their desk with both feet flat on the floor. Their notebook is centered on the desk in front of them, the pencil resting gently in their right hand while their left hand supports the page. They shift attention from the board to the notebook effortlessly as they write. Each change in gaze is quick and accurate, so they easily find where they left off.

As the teacher speaks, they listen and match what she says with what is on the board, writing the important notes neatly. They pay no attention to a classmate waving and tapping a pencil at the desk beside them.

After school they have a snack and immediately get to work on homework and on studying for tomorrow’s quiz on the planets. They take out their notes and read through them a few more times, visualizing each planet in sequential order and attaching the important details of each one to the mental images they create. They finish promptly and have time to relax before bed. The next day they score 100% on their science quiz.

Student B

This student sits at their desk with their feet wrapped around the legs of their chair. Their notebook is off to the right side of the desk, their pencil tightly gripped, their left arm draped across the page. Each time they shift from the board to their paper and back, their eyes feel weird and their vision gets blurry for a few seconds as they search for where they left off.

They are frantically trying to write down every word the teacher says, stopping often to shake out their hand while splitting attention between what she is saying and what is written on the board. As they try to focus on the lecture, their attention keeps getting pulled to the student beside them, waving and tapping a pencil on the desk.

After school they lie on the sofa and watch television because they are too tired to get their homework done. After 45 minutes of prompting from their parents, they finally sit down. An hour into the assignment they pull out their class notes, then spend the next hour deciphering their handwriting, trying to remember what was said in class, and looking up missing information on the internet. They study by repeating the information over and over. Eventually they feel confident they learned the material and go to bed. The next day they score 100% on their science quiz.

Same score, very different cost

Both are exemplary students with good grades. The difference is how much effort the same outcome required, and that is what a gradebook cannot show. Parents notice it first: the twenty-minute assignment that takes an hour, the child who is fine all day and falls apart at 7 p.m. Among third-, fifth- and seventh-graders, children whose parents reported more visual symptoms tended to have lower achievement scores, and the parents’ answers tracked achievement more closely than the children’s own (Vaughn et al., 2006) - an association in a small sample, not proof, but one that matches what we see.

The layers underneath a classroom skill

We find it useful to think of efficient learning as a stack rather than a single skill, with each layer supporting the one above it. That is a working framework borrowed from developmental optometry and occupational therapy, not a proven law of development, but it organizes what we look for. Our series follows that sequence.

Layer 1: Primitive reflexes

Babies are born with automatic movement patterns that normally fade as voluntary movement takes over. The idea behind reflex-integration work is that a lingering reflex costs effort to suppress - effort that is then not available for sitting still or holding a gaze. That is a model, not a proven mechanism.

The evidence here is weak, so give it limited weight. Persisting reflexes are common even in typically developing preschoolers, where greater persistence tracked with lower motor efficiency (Gieysztor et al., 2018). A systematic review linked reflex persistence with weaker balance, dexterity, reading, spelling and math, but called the studies limited and heterogeneous and the interventions promising rather than proven (Provazník et al., 2026). Researchers studying reading concluded reflex persistence cannot serve as a causal model for reading difficulty (McPhillips and Sheehy, 2004). We treat retained reflexes as a screening observation, not a diagnosis - see our primitive reflexes page.

Layer 2: The sensory systems

Touch, movement, body position, hearing and vision each deliver information the brain must sort and merge. When a child cannot filter what does not matter, a tapping pencil three feet away wins the competition for attention.

Layer 3: The motor systems

Body awareness, bilateral coordination, motor planning and eye movement control develop here, which is why posture belongs in this conversation. In our exam rooms we often read a child who hooks their feet around the chair legs as buying stability so the eyes and hand can work - that is our clinical read, not a research finding. Fine motor performance is measurably related to how well the two eyes work together for depth (O’Connor et al., 2010), and in preschoolers, motor difficulty is associated with language, executive-function and academic difficulty (McWhirter et al., 2024).

Layer 4: Visual and cognitive skills

Only at the top do classroom skills appear: sustained focus at near, accurate copying from board to page, and reading itself, which runs on a precise sequence of quick eye jumps and brief pauses (Rayner, 1998). With the lower layers solid, this is automatic. Without them, it costs effort.

What the evidence does and does not support

This field is contested, so we will be plain. Pediatric and ophthalmology bodies state that dyslexia is language-based, that vision problems can interfere with learning but do not cause dyslexia, and that eye exercises and behavioral vision therapy are not supported treatments for learning disabilities (AAP/AAO/AAPOS/AACO, 2009). Optometric bodies hold that vision problems can and often do interfere with learning, and that optometric care aims to improve visual function and relieve symptoms within a team approach (AAO/AOA, 1997).

The data sit in between. Children with developmental dyslexia had more accommodative and tracking deficits than typical readers, 79% versus 33% for any visual deficit, though the authors called the clinical meaning uncertain (Raghuram et al., 2018). Yet the largest randomized test of the reading question found that treating convergence insufficiency improved reading comprehension no more than placebo therapy did (CITT-ART, 2019).

Our clinical perspective, offered as ours and not as settled science: we do not treat reading and we do not promise better grades. We look for focusing, eye-teaming, eye-movement and visual-processing problems that make near work uncomfortable, and we treat those so a child’s effort goes into learning instead of into seeing. That is the work on our learning-related vision page.

The rest of the series

• Part 2: Primitive reflexes - the five reflex patterns with the biggest classroom impact.
• Part 3: Sensory systems - the seven senses, including two most parents have never heard of.
• Part 4: Motor systems - body schema, laterality and directionality, bilateral integration and ocular motor control.

When it is worth having a child evaluated

Watch effort, not just outcome. Consider an evaluation if your child dreads homework, loses their place when copying, holds their head close to the page or turns it to write, says words blur or move, is unusually tired after school, or sits in the braced, twisted posture Student B does.

A school screening that checks distance letters is a different test. The American Optometric Association recommends comprehensive examinations at 6 to 12 months, once between ages 3 and 5, before first grade and annually after that, and reports that acuity screening alone missed most children later found on full examination to have binocular and eye-movement problems (AOA, 2017).

If this sounds like your child, we would be glad to take a careful look. Schedule an evaluation at our Boynton Beach or Boca Raton office, or see what a developmental vision evaluation involves.
