Arnau is a 7-year, 4-month-old boy enrolled in 2nd grade at Escola Montserrat, a publicly funded primary school in Sant Andreu de Palomar, Barcelona. Born in 2016 to a Catalan-speaking mother and Spanish-speaking father, he uses both languages daily—Catalan at school and home during weekdays, Spanish during weekend family visits to Girona. In February 2023, he received a clinical diagnosis of ADHD-Inattentive Type (DSM-5 criteria) following evaluation at Hospital Sant Joan de Déu’s Child Neuropsychology Unit. Concurrently, occupational therapy assessment confirmed mild developmental coordination disorder (DCD), commonly referred to as dyspraxia, with standardized Movement Assessment Battery for Children, Second Edition (MABC-2) scores placing him at the 12th percentile for manual dexterity and 18th percentile for aiming and catching. This profile synthesizes 22 months of multidisciplinary data—including WISC-V subtest scores, teacher rating scales (Conners-3), handwriting samples measured with the Minnesota Handwriting Assessment (MHA), and weekly observational logs—to inform inclusive pedagogical practice.
Developmental Context and Linguistic Profile
Arnau’s bilingualism is additive rather than subtractive: he demonstrates age-appropriate receptive vocabulary in both Catalan (PPVT-Cat: standard score 102) and Spanish (PPVT-ES: standard score 99), per assessments administered in October 2023 using the Peabody Picture Vocabulary Test, Fourth Edition (PPVT-4) normed for Catalan and Spanish speakers. His expressive language shows asymmetry—he produces more complex syntactic structures in Catalan (mean length of utterance: 6.8 words) than in Spanish (MLU: 5.2 words), likely due to greater classroom exposure and peer modeling in Catalan. Crucially, his bilingual advantage manifests in metalinguistic awareness: on the Language Processing Scale (LPS), he scored at the 91st percentile in phonological segmentation tasks across both languages, outperforming monolingual peers by an average of 1.4 standard deviations.
This linguistic duality informs his learning strategies. For example, when solving multi-step math word problems, Arnau consistently translates instructions into Catalan first—even when presented in Spanish—before generating solutions. Teachers report that providing bilingual glossaries (e.g., suma/suma, resta/resta) increases his problem-solving accuracy by 37%. His dual-language fluency also buffers emotional regulation: during transitions or unstructured periods, self-talk in Catalan (“Respira. Pensa. Fes-ho pas a pas.”) correlates with 58% fewer off-task episodes compared to silent or Spanish-only self-cueing.
Cognitive Strengths and Executive Functioning Patterns
Arnau’s WISC-V profile reveals a pronounced scatter: Verbal Comprehension Index (VCI) = 116 (86th percentile), Visual Spatial Index (VSI) = 122 (93rd percentile), but Working Memory Index (WMI) = 81 (10th percentile) and Processing Speed Index (PSI) = 76 (5th percentile). His highest subtest score was Matrix Reasoning (15, 95th percentile), indicating exceptional nonverbal abstract reasoning—particularly with geometric patterns, symmetry, and spatial transformations. He independently solved all 12 puzzles in the ThinkFun Rush Hour logic game at Level 40 (the highest tier) within 90 seconds average time, a benchmark typically achieved by neurotypical children aged 10–11 years.
His working memory limitations are highly task-specific. Digit Span Forward is solid (span of 6), but Backward collapses to span 3—a 3-point deficit relative to age norms. Similarly, Letter-Number Sequencing yields only 4 correct sequences out of 8 trials. Yet in authentic contexts—such as remembering multi-part art project instructions (“Cut three blue triangles, glue them to the yellow circle, then add glitter to the edges”)—he succeeds 89% of the time when paired with visual anchors (e.g., laminated step cards with icons). This dissociation underscores that his challenges lie not in capacity per se, but in executive control under time pressure or without external scaffolds.
Educational Engagement and Academic Progress
From September 2022 through May 2024, Arnau’s academic trajectory was tracked using curriculum-aligned benchmarks from Catalonia’s Decret 187/2015 (Primary Education Curriculum). In reading fluency (measured via Lectura en Veu Alta protocol), his words-per-minute increased from 42 (below 25th percentile for Grade 2) to 78 (above 75th percentile) after implementing daily 10-minute paired reading with sentence-level cloze passages and auditory feedback via SpeechLogger software. His comprehension accuracy rose from 54% to 86% on inferential questions—especially those requiring character motive analysis or cause-effect sequencing.
In mathematics, he excels in conceptual understanding but struggles with procedural execution. On the Prova de Competències Bàsiques (PCB) diagnostic, he correctly identified fraction equivalence (e.g., 2/4 = ½) and area models for multiplication—but made 11 calculation errors in a 20-item addition/subtraction drill due to misaligned columns and skipped regrouping steps. Structured graph paper (5mm grid, used with Stabilo Point 88 Fine Tip pens) reduced arithmetic errors by 63% over 12 weeks. His science project on plant growth—completed with tactile soil sampling, time-lapse photography using a Canon EOS M50 Mark II, and annotated Catalan/Spanish captions—earned top marks for scientific reasoning and multimodal communication.
Motor Development and Sensory Integration
Arnau’s MABC-2 results confirm mild DCD: Manual Dexterity raw score = 12/36 (12th %ile), Aiming and Catching = 14/36 (18th %ile), Balance = 16/36 (34th %ile). His handwriting, assessed via the Minnesota Handwriting Assessment (MHA), showed consistent issues: letter formation irregularity (42% of letters deviated >2mm from baseline), inconsistent sizing (range: 2.1–4.8mm height vs. target 3.5mm), and slow speed (12.3 words/minute vs. class mean 21.7). Occupational therapy (OT) intervention twice weekly since January 2023 included Handwriting Without Tears’s wooden “Wet-Dry-Try” method and proprioceptive input via TheraBand resistance loops during seated writing tasks.
Sensory processing, evaluated using the Short Sensory Profile-2 (SSP-2), revealed significant registration difficulties: he frequently misses auditory cues (e.g., fails to respond to his name called once, requires 2–3 repetitions), yet displays tactile defensiveness around clothing tags and certain food textures (e.g., refuses cooked carrots but eats raw ones). Classroom accommodations include a designated “quiet corner” with weighted lap pad (Weighted Blanket Co. 1.5kg model), noise-dampening headphones (Loop Quiet), and scheduled proprioceptive breaks every 45 minutes—such as wall pushes (10 reps), chair push-ups (8 reps), or carrying stacked books (3–4kg total).
Classroom Supports and Evidence-Based Interventions
Arnau’s individualized support plan integrates Universal Design for Learning (UDL) principles with targeted neuropsychological strategies. Three core interventions demonstrate robust efficacy:
- Structured Movement Breaks: Using a Timer Pro visual countdown timer set to 45-minute intervals, Arnau performs 3-minute gross-motor activities (e.g., jumping jacks, crab walks, balance beam stepping). Teacher logs show this reduced off-task behavior from 22 to 8 instances per 90-minute block.
- Dual-Language Visual Scaffolds: All instructions are provided in parallel Catalan/Spanish text with embedded icons (e.g., a clock icon next to “10 min”, a pencil icon beside “write”). This cut assignment non-completion rates from 31% to 9% in Q3 2023.
- Self-Monitoring Checklists: Custom laminated checklists with Velcro-toggled icons allow Arnau to track task initiation, material organization, and completion. Weekly fidelity checks show 94% adherence, correlating with 42% higher on-task engagement (per ABC continuous recording).
Technology integration further enhances access. He uses Read&Write for Google Chrome for text-to-speech on digital worksheets and Microsoft Immersive Reader to adjust line spacing (1.5x), font (Open Dyslexic), and syllable highlighting. For math, DragonBox Numbers’ gamified interface helped him internalize number composition/decomposition concepts—his post-intervention Number Sense Screener score rose from 58 to 89 (out of 100).
Social-Emotional Development and Peer Interaction
Arnau’s social profile reflects asynchronous development: he reads facial expressions accurately (92% on the Reading the Mind in the Eyes Test—Child Version) but struggles with real-time reciprocity. During group work, he often dominates topic selection (e.g., insisting on dinosaur facts during a weather unit) yet withdraws if peers interrupt or shift subjects abruptly. The Social Responsiveness Scale-2 (SRS-2) teacher form yielded a T-score of 68 (borderline clinical range) for Social Awareness and 74 (clinical range) for Autistic Mannerisms—though clinical consensus ruled out ASD due to absence of restricted interests or sensory-seeking behaviors beyond his documented tactile sensitivities.
Peer-mediated intervention has yielded measurable gains. Since November 2023, Arnau participates in biweekly Friendship Circles facilitated by the school psychologist, using Social Thinking® curricula (We Thinkers! Volume 2). Role-play scenarios focus on “thinking with your eyes,” “body in the group,” and “adding comments vs. taking over.” Pre/post sociometric ratings show his peer nomination count increased from 2 to 7 classmates selecting him as “someone I like to work with”—a 250% improvement. Crucially, teacher observations note he now initiates turn-taking 68% of the time in partner reading, up from 23% pre-intervention.
Family Collaboration and Home-School Alignment
Consistency between home and school environments significantly amplifies Arnau’s progress. His parents use the same visual schedule system (First-Then Board from Do2Learn) for morning routines: “First: brush teeth (timer set to 2 min), Then: choose breakfast fruit.” They co-developed a “Focus Kit” containing a Time Timer MAX (with audible chime), fidget tools (Tangle Jr., Pop It!), and laminated emotion cards (Zones of Regulation visuals). Weekly shared logs via ClassDojo document behavioral patterns—e.g., noting that sugar intake >15g at breakfast correlates with 3.2x more disengagement episodes during morning literacy blocks.
Parent interviews reveal key insights: Arnau’s ability to sustain attention triples during hands-on, interest-driven tasks—especially those involving natural elements. His backyard composting project (monitoring decomposition rates of apple cores vs. plastic wrappers over 8 weeks) maintained 22+ minutes of focused observation, versus 4–6 minutes during conventional seatwork. This aligns with research on intrinsic motivation in neurodivergent learners (Ryan & Deci, 2000); his science teacher now embeds choice boards with ecology-themed options for all units.
Assessment Data and Longitudinal Trends
Quantitative tracking confirms durable gains across domains. The table below summarizes standardized metric changes from baseline (Sept 2022) to follow-up (May 2024):
| Metric | Baseline (2022) | Follow-up (2024) | Change |
|---|---|---|---|
| Reading Fluency (wpm) | 42 | 78 | +36 (+86%) |
| Math Calculation Accuracy (%) | 61 | 89 | +28 (+46%) |
| Handwriting Legibility Score (MHA) | 14/30 | 24/30 | +10 (+71%) |
| Off-Task Episodes (per 90-min) | 22 | 8 | -14 (-64%) |
| Peer Nominations (social preference) | 2 | 7 | +5 (+250%) |
| Homework Completion Rate (%) | 54 | 89 | +35 (+65%) |
These improvements were achieved without pharmacological intervention; his parents opted for behavioral and environmental supports following guidance from Hospital Sant Joan de Déu’s ADHD Family Support Program. Notably, gains persisted through summer 2023—when he attended a bilingual nature camp (Ca la Nena in Besalú)—indicating skill generalization beyond classroom contexts.
Implications for Inclusive Curriculum Design
Arnau’s case challenges monolithic assumptions about attention, language, and ability. His profile validates several evidence-based design principles:
- Temporal Flexibility: Replacing rigid 45-minute lesson blocks with 25-minute focused segments + 5-minute transition buffers increased his task initiation compliance from 62% to 94%.
- Material Multimodality: Providing science content via National Geographic Kids videos (Catalan-dubbed), tactile rock kits, and illustrated glossaries raised concept retention from 51% to 83% on unit quizzes.
- Strength-Based Scaffolding: Leveraging his visual-spatial strength, teachers replaced traditional spelling lists with “word architecture” diagrams—building orthographic knowledge through shape mapping (e.g., “girar” drawn as a spiral; “correr” as two parallel lines with arrows).
Curriculum adaptations must avoid lowering expectations. When Arnau’s class studied the water cycle, he was assigned the same learning objectives as peers—but accessed them through differentiated pathways: while others wrote paragraphs, he produced a stop-motion animation (iMovie) with bilingual narration and labeled diagrams. His final product met all rubric criteria for scientific accuracy, sequencing, and explanatory clarity—and earned full credit.
Future Directions and Research Considerations
Looking ahead, Arnau’s team prioritizes three goals for 2024–2025: (1) expanding his self-advocacy skills through explicit instruction in requesting accommodations (e.g., “I need the timer reset” vs. “I’m stuck”); (2) introducing cursive writing using LoEsquema’s motor-practice approach, given his strong visual memory for letter forms; and (3) piloting a peer-buddy system for unstructured recess, targeting sustained cooperative play. Ongoing data collection will track whether his high visual-spatial aptitude predicts success in computational thinking—specifically, his performance on Code.org’s Express Course (Grades 2–5), where spatial logic underpins debugging and algorithmic sequencing.
From a research perspective, Arnau exemplifies why population-level special education metrics can obscure individual potential. His WISC-V PSI score (76) falls in the “Borderline” classification—but in context, it reflects inefficient processing under timed conditions, not global cognitive limitation. Standardized labels risk eclipsing assets: his ability to hold complex spatial relationships in mind surpasses 93% of same-age peers, a strength directly applicable to engineering, cartography, and data visualization. Future curriculum frameworks must integrate asset-based assessment batteries—not just deficit-focused screens—to ensure neurodivergent children like Arnau are positioned as innovators, not just accommodated learners.
His story also highlights infrastructure gaps. Escola Montserrat lacks dedicated OT space; Arnau receives services in a repurposed storage closet (2.4m × 1.8m), limiting equipment variety. District-level advocacy has secured funding for a sensory-motor room by 2025—a 12m² space equipped with Sammons Preston therapy mats, Spalding balance beams, and Abilitations tactile walls. Such investments don’t merely serve Arnau; they benefit all students, including those with anxiety, trauma histories, or undiagnosed sensory needs.
Arnau’s growth isn’t measured in normalized percentiles alone—it’s visible in his confident voice explaining photosynthesis to kindergarteners during cross-grade science fair, in his neatly organized “focus backpack” with color-coded folders, and in his mother’s note: “He told me yesterday, ‘Mama, my brain works different, but it works.’” That self-awareness, nurtured through respectful, data-informed support, remains the most vital outcome of all.
His journey affirms that inclusion isn’t about fitting children into static systems—it’s about redesigning systems to honor how diverse minds learn, create, and contribute. When educators recognize that attention isn’t singular but multifaceted, that language isn’t a barrier but a bridge, and that motor challenges don’t define cognitive capacity, they unlock possibilities no standardized test can capture.
For curriculum designers, Arnau’s profile underscores a non-negotiable principle: accessibility features built for neurodivergent learners—like visual timers, bilingual glossaries, and flexible pacing—are universal tools that enrich learning for everyone. A timer benefits the anxious student; dual-language supports aid immigrant families; movement breaks improve circulation and focus for all. His classroom isn’t an exception—it’s a prototype.
At the heart of effective practice lies consistency—not rigidity. Consistent expectations paired with variable pathways. Consistent warmth paired with precise, individualized scaffolds. Consistent belief in capability, even when progress is nonlinear. Arnau’s 42% engagement gain wasn’t magic; it was the cumulative effect of 22 months of calibrated observation, collaborative problem-solving, and unwavering affirmation of his whole, complex, brilliant self.
His favorite phrase, written in careful Catalan script on his desk plaque, reads: “Jo sóc capaç. Només necessito una mica de temps i les eines adequades.” (“I am capable. I just need a little time and the right tools.”) That statement, grounded in evidence and lived experience, is the compass guiding every decision in his educational journey—and a north star for inclusive design everywhere.
