Providing Instruction and Modifying Curriculum
Explicit teaching, then systematic adjustment
Strong instruction for students with disabilities is explicit and systematic: state the objective, model with clear language, provide guided practice with high rates of opportunities to respond, give immediate corrective feedback, move to independent practice, and build in cumulative and distributed review. Task analysis breaks complex skills into teachable steps; scaffolding is faded as competence grows. Progress monitoring with curriculum-based measures and decision rules (for example, examining the trend across several consecutive data points) turns instruction into an evidence-based loop rather than a hunch.
In reading, address phonemic awareness, phonics, fluency, vocabulary, and comprehension explicitly; code-based instruction is essential for students with word-reading disabilities, repeated reading builds fluency, and text-structure and strategy instruction supports comprehension. In mathematics, a concrete-to-representational-to-abstract sequence, explicit schema instruction, and mnemonic devices are well supported. Cooperative learning, peer tutoring, self-monitoring, and graphic organizers are effective when they carry the cognitive work rather than replace it.
The distinction candidates most often miss is accommodation versus modification. An accommodation changes how the student accesses content without changing the expectation: extended time, preferential seating, a read-aloud, a word bank, a graphic organizer, audiobooks. A modification changes what is expected: fewer items, below-grade-level text, an alternate achievement standard. Co-teaching models - one teach/one assist, station teaching, parallel teaching, alternative teaching, team teaching, and one teach/one observe - are selected by purpose, not preference. Assistive technology, whether a device or a service, must be considered for every student with an IEP.
Rule of thumb: if the student is still held to the same grade-level standard, it is an accommodation; if the standard itself is lowered, it is a modification, and the IEP must say so.
