# Special Education and Learning Differences

## Common learning differences

### Dyslexia

Reading and language processing difficulty. NOT related to intelligence.
Signs: Difficulty with phonological awareness, decoding, reading fluency, spelling.
Prevalence: 15-20% of the population.
Evidence-based interventions: Structured literacy (Orton-Gillingham, Wilson Reading, SPIRE). Systematic phonics, phonemic awareness, fluency, comprehension.
Accommodations: Extended time, audiobooks, text-to-speech, reduced writing demands.

### ADHD (Attention-Deficit/Hyperactivity Disorder)

Executive function difficulty. Impacts attention regulation, impulse control, working memory.
Primarily Inattentive, Primarily Hyperactive-Impulsive, or Combined presentation.
Environmental supports: Short task segments, frequent breaks, movement, reduced distraction, clear structure.
Technology helps: Timers, reminders, task management apps.

### Dyscalculia

Difficulty processing numbers and mathematical concepts.
Accommodations: Calculator use, extra time, visual/tactile representations, graph paper.
Instruction: Concrete → Representational → Abstract (CRA approach).

### Autism Spectrum Disorder (ASD)

Wide variation. May impact: social communication, sensory processing, restricted interests, executive function.
Supports: Predictable structure, visual schedules, clear explicit instructions, sensory accommodations, interest-based learning.

## IDEA and IEPs (US context)

**IDEA (Individuals with Disabilities Education Act):** Federal law guaranteeing free and appropriate public education (FAPE) in least restrictive environment (LRE).

**IEP (Individualized Education Program):**
Required for eligible students. Annual document.
Must include: Present levels of performance, measurable goals, special education services, related services, accommodations/modifications, transition planning (age 16+).
Parents are equal partners in IEP development.

**504 Plan:** For students who need accommodations but don't qualify for special education.
Common 504 accommodations: Extended time, preferential seating, reduced distraction environment, copies of notes.

## Universal Design for Learning (UDL — CAST)

Design learning environments accessible to all from the start — not retrofitted.
Three principles:
**Multiple means of representation:** Present information in various formats (visual, auditory, text).
**Multiple means of action and expression:** Let students demonstrate learning in varied ways.
**Multiple means of engagement:** Provide options for interest, persistence, and self-regulation.
Good UDL often eliminates the need for individual accommodations.

## Supporting diverse learners: practical strategies

**Chunking:** Break complex tasks into smaller steps.
**Explicit instruction:** Don't assume implicit understanding. State it directly.
**Check for understanding frequently:** Not "Does everyone understand?" but "Tell me step one."
**Reduce cognitive load:** Simplify instructions, one step at a time, visual supports.
**Strength-based approach:** What can this learner do? Build from there.
**Environment:** Minimize distractions, predictable routines, sensory considerations.
