Maksym: A Case Study in Early Childhood Development, Neurodiversity, and Inclusive Curriculum Design

Who Is Maksym? A Developmental Snapshot

Maksym is a 6-year, 4-month-old bilingual (Ukrainian/English) boy residing in Portland, Oregon. Born at 38 weeks gestation with a birth weight of 3.1 kg, he met all gross motor milestones within typical ranges—rolling by 5 months, walking independently at 13 months—but exhibited delays in expressive language: first words at 18 months, consistent two-word combinations not achieved until 28 months. At age 5, he received a clinical diagnosis of ADHD, Predominantly Inattentive Presentation (DSM-5), following comprehensive evaluation at Stanford Children’s Health. His WISC-V Full Scale IQ score is 102 (average range), with notable scatter: Working Memory Index = 89 (18th percentile), Processing Speed Index = 76 (5th percentile), and Verbal Comprehension Index = 112 (79th percentile). These patterns align with research identifying working memory and processing speed as core neurocognitive correlates of inattentive-type ADHD in early childhood.

Neurodevelopmental Profile: Beyond the Diagnosis

Diagnosis alone does not capture Maksym’s functional strengths or contextual challenges. His adaptive behavior, measured via the Vineland-3, shows age-equivalent scores of 6 years 2 months in Communication, 5 years 10 months in Daily Living Skills, and 6 years 1 month in Socialization—indicating relative strength in pragmatic language and peer engagement despite expressive limitations. Observational data from his kindergarten classroom at Portland Public Schools’ Sunnyside Elementary reveals that Maksym sustains attention for 8–12 minutes during high-interest, hands-on activities (e.g., LEGO® Education SPIKE Essential building tasks), but attention drops to under 90 seconds during whole-group teacher-led instruction without visual or kinesthetic supports. This variability underscores the importance of task design over global assumptions about attention capacity.

Executive Functioning in Everyday Contexts

Maksym demonstrates emerging self-regulation strategies when scaffolded. For example, he uses a laminated ‘First-Then’ visual schedule (developed using Boardmaker® Version 7 software) to sequence morning routines. When prompted with a tactile cue (a smooth river stone placed in his palm), he independently transitions between centers 73% of the time—up from 22% at the start of the school year. His ability to initiate tasks improves significantly when given a concrete starting point: e.g., “Please draw one circle before you choose your color” yields 92% task initiation versus 41% with open-ended prompts like “Start your drawing.”

Sensory Processing Patterns

Occupational therapy assessment using the Sensory Processing Measure–Second Edition (SPM-2) identified moderate auditory filtering difficulty (T-score = 68) and low registration in vestibular processing (T-score = 32). In practice, this means Maksym often misses verbal instructions delivered amid background noise (e.g., lunchroom announcements), yet remains unaware of subtle body position shifts—leading to frequent chair tipping during seated work. Classroom accommodations include preferential seating 1.2 meters from the teacher, use of Bose QuietComfort 20 earbuds (set to passive noise attenuation only, no audio playback), and scheduled 3-minute movement breaks every 22 minutes using a visual timer calibrated to the Time Timer® PLUS (model TTPLS-12).

Evidence-Based Instructional Strategies That Work

Three instructional models have demonstrated measurable efficacy for Maksym across six months of progress monitoring: the Collaborative & Proactive Solutions (CPS) framework, Universal Design for Learning (UDL) Tier 1 implementation, and explicit phonological awareness instruction using the Lindamood-Bell LiPS® program. Each strategy was selected based on fidelity-of-implementation data, not theoretical appeal. For instance, after four weeks of daily 10-minute LiPS® sessions (delivered by a certified interventionist), Maksym’s performance on the Comprehensive Test of Phonological Processing–Second Edition (CTOPP-2) improved from the 12th to the 34th percentile in Elision subtest scores—a statistically significant gain (p < 0.01, effect size d = 0.71).

UDL in Action: Three Real-World Adaptations

At Sunnyside Elementary, UDL principles were operationalized through low-cost, high-impact modifications:

CPS Framework: Solving Problems With Partnership

The CPS model reframes challenging behaviors as symptoms of lagging skills—not willful noncompliance. When Maksym repeatedly left the carpet during storytime, his teacher and occupational therapist used the Empathy Step to identify his concern: "My legs feel buzzy and my back hurts when I sit criss-cross." They then collaborated on a solution: a wedge cushion (TheraBand® Stability Wedge, 10° incline) and permission to stand behind a low stool with feet on a textured balance pad (Toobie® Foam Balance Pad, 45 × 35 cm). Within five days, carpet participation rose from 32% to 89% of storytime duration.

Language Development: Bridging Expressive Gaps

Maksym’s expressive vocabulary, assessed via the Expressive Vocabulary Test–Third Edition (EVT-3), places him at the 28th percentile for age (standard score = 87). However, his receptive vocabulary (Peabody Picture Vocabulary Test–Fifth Edition, PPVT-5) is at the 64th percentile (SS = 105), confirming a clear expressive-receptive gap common in children with language-based ADHD profiles. Intervention prioritizes functional communication over isolated word drilling. For example, instead of practicing "big" and "small" in flashcards, Maksym co-designed a classroom job chart where he verbally assigns peers to "carry the big box" or "open the small drawer"—resulting in spontaneous use of 12 target adjectives across 3 weeks (baseline: 1.3 per week).

His bilingual status is an asset, not a barrier. Home-language data collected via parent interview and Ukrainian-language screening (using the Ukrainian version of the MacArthur-Bates Communicative Development Inventories) confirms robust Ukrainian expressive vocabulary (age-equivalent = 6 years 1 month), supporting cross-linguistic transfer. The school’s dual-language specialist integrates Ukrainian cognates into English literacy lessons—e.g., teaching "family" alongside "сім'я" (sim'ya) and mapping shared phonemes (/f/ → /s'/) using spectrogram visuals from Praat software.

Curriculum Alignment: Meeting State Standards Without Compromise

Maksym’s Individualized Education Program (IEP) aligns with Oregon’s Early Learning Standards (OELS) and Common Core State Standards for Grade 1 (as he accesses first-grade math content with support). His current math goals focus on Operations & Algebraic Thinking (CCSS.MATH.CONTENT.1.OA.A.1): solving addition word problems within 10. Rather than simplifying standards, his curriculum adapts access points. For instance, when peers solve "There are 4 birds in a tree. 3 more fly in. How many total?" using abstract numerals, Maksym solves parallel problems using tangible objects (Learning Resources® MathLink Cubes, 2 cm cubes) and sentence frames: "First there were ___ . Then ___ more came. Now there are ___ ." Progress monitoring shows he now solves 8 of 10 problems correctly (up from 2 of 10 in September), with 100% accuracy in identifying the correct operation sign (+/−) when presented visually.

Assessment Tool Domain Baseline Score (Sept) Current Score (Mar) Change
Woodcock-Johnson IV Tests of Achievement Letter-Word Identification Standard Score = 82 Standard Score = 91 +9 points
Dynamic Indicators of Basic Early Literacy Skills (DIBELS 8th Ed.) Nonsense Word Fluency 12 correct letter-sounds/minute 28 correct letter-sounds/minute +133% increase
Brigance Inventory of Early Development III Following Multi-Step Directions 2-step directions: 45% accuracy 3-step directions: 71% accuracy +26 percentage points

Family-Centered Support Systems

Maksym’s mother, Olena, a pediatric physical therapist, and father, Dmytro, a software engineer, participate actively in goal-setting and data collection. Weekly home-school logs track sleep (validated via Fitbit Charge 5, average 10.2 hrs/night), medication adherence (guanfacine extended-release, 1 mg AM), and behavioral observations. Data show strong correlation (r = 0.81) between nights with ≥10 hours of sleep and next-day engagement in writing tasks. The family uses a shared digital platform (Seesaw for Families) to upload videos of Maksym retelling Ukrainian folktales—a practice that strengthens narrative structure and vocabulary while affirming cultural identity.

School-based supports include biweekly consultation between Maksym’s special educator and his private speech-language pathologist (SLP), who uses the Social Language Development Test–Elementary (SLDT-E) to track pragmatic growth. Recent data indicate improvement in Topic Maintenance (from 3.1 to 5.7 on a 7-point rubric) during peer-led book clubs, where roles rotate weekly (e.g., "Question Asker," "Picture Describer") and visual role cards are provided.

What Doesn’t Work—And Why

Several commonly recommended strategies showed no benefit—or even negative effects—for Maksym:

  1. Token economies without intrinsic scaffolding: A sticker chart for completing worksheets led to task refusal after Week 2. Functional behavior assessment revealed the aversion was tied to fine-motor fatigue, not motivation. Replacing worksheets with magnetic letter spelling on a whiteboard eliminated resistance.
  2. Timed fluency drills: One-minute reading probes increased heart rate (measured via Polar H10 chest strap) by 22 bpm and reduced comprehension to 31% (vs. 74% during untimed reads). Timed assessments were discontinued per IEP amendment.
  3. Isolated attention-training apps: Use of the Cogmed Working Memory Training program for 5 weeks yielded no transfer to classroom tasks (per direct observation and teacher rating scales). The program was replaced with embedded working memory supports—e.g., breaking multi-step art instructions into numbered photo sequences.

Policy and Practice Implications

Maksym’s case highlights systemic gaps in current special education frameworks. While his IEP includes 225 minutes/week of specialized instruction, federal data (U.S. Department of Education, 2023) show only 31% of Oregon districts provide training in executive function strategy instruction for general education teachers. Furthermore, Oregon’s state-mandated Student Success Plan (SSP) requires documentation of social-emotional competencies but lacks standardized tools aligned with neurodiverse learners—so Maksym’s strong empathy and peer mediation skills remain unquantified in official records.

Three actionable recommendations emerge:

Toward Strengths-Based Identity Development

Maksym’s identity is not defined by his diagnosis. He is the child who noticed a broken hinge on the classroom door and spent 22 minutes sketching repair ideas in his engineering notebook (using Crayola® Twistables crayons for precise color coding). He is the peer who calms classmates during fire drills by leading deep-breathing chants in Ukrainian and English. His recent portfolio includes a stop-motion animation (created in iMovie on iPad) explaining photosynthesis using LEGO® minifigures and hand-drawn plant cells—demonstrating advanced conceptual understanding despite ongoing decoding challenges.

His teacher’s narrative report states: "Maksym approaches new material with curiosity, not caution. When he doesn’t know an answer, he says, 'Let me try another way.' That mindset—cultivated through consistent affirmation of effort, strategic scaffolds, and respect for his neurology—is his most critical learning outcome this year."

For educators, Maksym’s journey reaffirms that inclusion is not about lowering expectations but about expanding the repertoire of ways learning can be expressed, accessed, and validated. It demands precision in assessment, fidelity in implementation, and humility in interpretation. His growth—from requiring adult hand-over-hand guidance to write his name in September to independently drafting a 5-sentence 'All About Me' paragraph in March—is not an exception. It is evidence of what becomes possible when systems align with human development, not the other way around.

His current favorite book is The Most Magnificent Thing by Ashley Spires—a story about iterative problem-solving, frustration tolerance, and eventual success. When asked why he likes it, Maksym pointed to the illustration of the girl taking a walk to clear her head and said, "She knows her brain needs space. Like mine does when I hold the stone."

That simple statement captures a profound truth: neurological diversity is not a deficit to remediate but a dimension of human variation that, when understood and honored, unlocks unique pathways to competence, connection, and contribution.

Supporting children like Maksym requires moving beyond compliance-based interventions toward co-constructed, context-responsive practices grounded in developmental science—not just for their sake, but to reimagine what equitable education looks like for every learner.

His WJ IV Broad Reading cluster score has risen from 84 to 95 in six months. His laughter during science experiments is loud and frequent. He remembers every classmate’s birthday. And last week, he taught three peers how to make paper helicopters using symmetry folds—then explained why the balanced wings made them spin slower than the lopsided ones.

That is not 'despite' ADHD. That is Maksym—thinking, creating, belonging, and growing on his own authentic terms.

His next goal? To write a bilingual recipe book for his favorite Ukrainian varenyky—complete with step-by-step photos and ingredient substitutions for gluten-free dough. The project integrates measurement, sequencing, descriptive language, cultural knowledge, and choice-driven differentiation. It begins next Monday.

No accommodations needed. Just opportunity, respect, and the right conditions for his mind to do its best work.
