Question 1

The term 'specific language impairment' (SLI), now often called 'developmental language disorder' (DLD), differs from dyslexia primarily in that DLD involves:

Accepted Answer

Oral language deficits that precede and accompany literacy difficulties

Answer

DLD/SLI involves pervasive oral language deficits (grammar, vocabulary, narrative) that exist before formal literacy instruction, whereas dyslexia primarily manifests in written language with relatively stronger oral language.

Question 2

Which research finding best supports structured literacy instruction over whole-language approaches for students with dyslexia?

Accepted Answer

The National Reading Panel (2000) found strong evidence for explicit, systematic phonics instruction

Answer

The National Reading Panel's 2000 report found strong scientific evidence that systematic, explicit phonics instruction is essential for all readers and especially critical for students with dyslexia.

Question 3

A student with dyslexia struggles most with reading pseudowords (nonsense words) compared to real words. This pattern primarily reflects a deficit in:

Accepted Answer

Phonological decoding using grapheme-phoneme rules

Answer

Pseudoword reading requires applying phonological decoding rules without any lexical support; poor pseudoword reading is a hallmark indicator of the phonological decoding deficit in dyslexia.

Question 4

Morphological awareness — understanding prefixes, roots, and suffixes — becomes increasingly important for reading development beginning at approximately which grade level?

Accepted Answer

4th grade and beyond

Answer

From approximately 4th grade onward, academic vocabulary becomes heavily morphologically complex, making morphological awareness critical for reading comprehension and spelling of multisyllabic words.

Question 5

Which of the following describes 'orthographic mapping,' as defined by David Kilpatrick?

Accepted Answer

The process by which phonemic awareness and letter-sound knowledge bond pronunciations to spellings in long-term memory

Answer

Orthographic mapping (Kilpatrick) is the mental process of using phonemic awareness and grapheme-phoneme knowledge to permanently store words' pronunciations, spellings, and meanings simultaneously in long-term memory.
