Reading and Writing

Domain 5: Reading and Writing

This domain tests literacy development for ELs: phonemic awareness, phonics, fluency, vocabulary, comprehension, writing process, genre, and the role of L1 literacy. Expect questions on selecting strategies by proficiency and text demand.

Core rules

  • Reading components: phonemic awareness, phonics, fluency, vocabulary, comprehension. Older newcomers may need accelerated phonics while still accessing grade-level meaning.
  • L1 literacy transfer: readers literate in L1 transfer decoding strategies, text structure, and academic habits; transfer is not automatic for all features.
  • Vocabulary: tiered words, cognates, morphological analysis, context clues, and repeated exposure. Teach both general academic and content-specific terms.
  • Comprehension: previewing, questioning, summarizing, text structure, and monitoring. Use texts with adequate support, not just simplified texts.
  • Writing: process (plan, draft, revise, edit, publish), genre awareness, sentence combining, and feedback. Error correction should target patterns, not every mistake.

Worked example

A Spanish-speaking student writes 'The plant need water for to grow.' The teacher identifies two patterns: subject-verb agreement (needs) and infinitive use (to grow). Instead of marking every error, the teacher gives a focused mini-lesson on third-person singular and infinitive purpose clauses, then asks the student to revise. Reasoning: one or two high-frequency patterns are more learnable than a fully marked paper.

Traps

  • Assuming a student who decodes English well comprehends academic text.
  • Using only simplified texts and never grade-level content with scaffolds.
  • Treating cognates as always identical in meaning (false cognates).
  • Correcting spelling and grammar so heavily that content and ideas are obscured.
  • Ignoring the difference between social and academic vocabulary.
