9.1 Supporting English Learners (ESOL / Multilingual Learners) in Reading Acquisition

Key Takeaways

  • Second language acquisition unfolds across five predictable developmental stages (Pre-production, Early Production, Speech Emergence, Intermediate Fluency, Advanced Fluency), requiring educators to tailor linguistic scaffolds without diluting cognitive challenge.
  • Jim Cummins' Dual-Iceberg Model establishes that Basic Interpersonal Communicative Skills (BICS) develop in 1–2 years, whereas Cognitive Academic Language Proficiency (CALP) requires 5–7+ years; conversational fluency must never be conflated with academic reading independence.
  • Under the Common Underlying Proficiency (CUP) principle, literacy competencies, conceptual schemas, and metacognitive habits established in a student's home language (L1) transfer directly to accelerate English (L2) reading acquisition.
  • Cross-linguistic phonological contrasts—such as Spanish's 5 pure vowel sounds versus English's 15+ vowel phonemes and absent consonants (/sh/, /th/, /v/)—account for systematic pronunciation and spelling approximations that reflect linguistic transfer rather than intrinsic processing deficits.
  • The Sheltered Instruction Observation Protocol (SIOP) framework enhances comprehension by pairing explicit content and language objectives with comprehensible input, multimodal realia, bilingual glossaries, and structured sentence frames.

Supporting English Learners (ESOL / Multilingual Learners) in Reading Acquisition

Quick Answer: Multilingual Learners acquire English literacy through five developmental stages (Pre-production, Early Production, Speech Emergence, Intermediate Fluency, and Advanced Fluency). Jim Cummins' Dual-Iceberg Model demonstrates that conversational fluency (BICS, acquired in 1–2 years) masks underlying needs in academic language (CALP, requiring 5–7+ years). Rather than viewing native languages as deficits, the Common Underlying Proficiency (CUP) model reveals that foundational literacy in L1 directly accelerates L2 reading acquisition. Educators must leverage Sheltered Instruction (SIOP) scaffolds—such as comprehensible input, realia, bilingual glossaries, cognates, and structured sentence frames—while distinguishing normal cross-linguistic phonological transfer from reading disabilities.


1. GACE Blueprint Alignment: Objective 0006 & Linguistic Diversity

Under GACE 350 Objective 0006 (Factors that May Affect Reading Development), Georgia educators must demonstrate a rigorous understanding of how environmental, cultural, neurobiological, and linguistic factors influence literacy acquisition. A significant portion of this objective centers on English Learners (ELs)—also termed English for Speakers of Other Languages (ESOL) or Multilingual Learners (MLs).

Historically, educational models treated second language acquisition through a subtractive deficit lens, operating under the misconception that non-English home languages hindered reading development. The Science of Reading and contemporary cognitive linguistics refute this premise. Multilingualism confers distinct cognitive and metalinguistic advantages. However, navigating an opaque alphabetic orthography like English while concurrently developing oral language proficiency presents unique instructional considerations that candidates must master for the GACE examination.


2. Krashen & Terrell's Stages of Second Language Acquisition

Second language acquisition is a gradual, developmental process governed by predictable stages. Formulated by Stephen Krashen and Tracy Terrell, this natural continuum guides educators in providing developmentally appropriate instructional scaffolds and setting realistic communicative expectations.

StageTypical TimeframeReceptive / Expressive VocabularyStudent Linguistic BehaviorsEvidence-Based Instructional Scaffolds
1. Pre-Production (The Silent Period)0 to 6 months~500 receptive words; minimal expressive speechFocuses on active listening, receptive processing; communicates via pointing, gesturing, nodding, and drawing; absorbs prosody and phonologyAvoid forced public oral production; utilize realia, visuals, physical demonstrations (Total Physical Response - TPR); assign bilingual peer buddies; lower the affective filter
2. Early Production6 to 12 months~1,000 receptive/active words; limited oral outputProduces 1–2 word utterances, memorized chunks, and routine phrases ("yes/no", "thank you", "here"); communicates in present tenseProvide forced-choice binary questions ("Is this an herbivore or a carnivore?"); use visual graphic organizers; supply simple sentence starters with pictorial supports
3. Speech Emergence1 to 2 years~3,000 active words; growing dialogueFormulates simple sentences; initiates conversations; exhibits frequent grammatical and syntax errors (e.g., omitted plural inflections, word order transfer from L1)Implement structured sentence frames; facilitate structured think-pair-share routines; model correct syntax through revoicing rather than overt correction; use dialogic read-alouds
4. Intermediate Fluency3 to 5 years~6,000 active words; complex speechSpeaks in compound and complex sentences; expresses personal opinions and debates; demonstrates substantial comprehension; fewer grammatical errorsExplicitly teach academic (Tier 2) vocabulary; provide transition-word banks and complex analytical sentence stems; utilize graphic organizers for expository text structures
5. Advanced Fluency5 to 7+ yearsNear-native communicative proficiency across contextsDemonstrates fluent academic literacy across all content areas; grasps idiomatic expressions, humor, and irony; writes and reads at or near grade levelProvide ongoing discipline-specific morphological and vocabulary enrichment; foster advanced metacognitive comprehension monitoring; refine subtle stylistic and rhetorical nuances

Detailed Analysis of Acquisition Stages

|                                 STAGES OF SECOND LANGUAGE ACQUISITION                                   |
+---------------------------------------------------------------------------------------------------------+
|  Stage 1: Pre-Production       --> Receptive listening, nonverbal responses, "Silent Period"            |
|  Stage 2: Early Production     --> 1-2 word utterances, memorized phrases, forced-choice prompts        |
|  Stage 3: Speech Emergence     --> Simple sentences, emerging dialogue, developmental grammar errors     |
|  Stage 4: Intermediate Fluency --> Complex sentences, academic discourse, analytical sentence frames    |
|  Stage 5: Advanced Fluency     --> Grade-level academic literacy, nuanced syntax, disciplinary idioms   |
+---------------------------------------------------------------------------------------------------------+

1. Pre-Production (The Silent Period)

In this initial window, students are not merely passive; their cognitive architecture is intensely engaged in auditory discrimination, segmenting the continuous stream of English speech into recognizable lexical and phonological units. Forcing oral reading or public speaking during this stage elevates the student's affective filter (anxiety, self-consciousness), which Krashen demonstrates impedes language acquisition. Instruction must prioritize comprehensible input through physical gestures, concrete artifacts, and non-verbal response options.

2. Early Production

Students begin to express basic needs and answer questions using single words or formulaic phrases. When assessing reading comprehension, teachers must refrain from requiring elaborate verbal explanations. Instead, prompt comprehension using closed questions, pointing tasks, or dual-option selections.

3. Speech Emergence

Students possess sufficient vocabulary to construct original sentences and engage in interactive literacy discussions. However, their speech and writing exhibit regular grammatical errors (e.g., omitting third-person singular -s as in "He walk to store" or confusing prepositions). These errors are natural signs of active linguistic hypothesis testing. Teachers should employ revoicing (repeating the student's idea with correct academic syntax and grammar: "Yes, he is walking to the store to purchase supplies") rather than punitive correction.

4. Intermediate Fluency

Learners communicate fluently in social settings and engage with complex academic ideas. However, when confronted with dense expository texts, they encounter bottlenecks in abstract Tier 2 vocabulary (e.g., evaluate, formulate, contrast) and intricate syntactic structures (e.g., passive voice, relative clauses). Scaffolds should shift toward text-dependent analysis, paragraph frames, and morphological deconstruction.

5. Advanced Fluency

Students demonstrate language capabilities comparable to native English-speaking peers. Continued support centers on disciplinary literacy—mastering the specialized registers of science, history, and literature.


3. Cummins' Dual-Iceberg Model: BICS vs. CALP & Common Underlying Proficiency

One of the most heavily tested theoretical frameworks on educator licensing exams is Jim Cummins' Dual-Iceberg Hypothesis of Language Interdependence.

                          THE DUAL-ICEBERG MODEL (JIM CUMMINS)

               Surface Features (L1)                 Surface Features (L2)

                            Metacognitive Strategies, Syntax]

BICS vs. CALP

Cummins distinguishes between two distinct dimensions of second language proficiency:

  1. Basic Interpersonal Communicative Skills (BICS):

    • The language of face-to-face, everyday social interactions (playground talk, cafeteria conversations, casual dialogue).
    • Heavily context-embedded: supported by situational cues, facial expressions, body language, gestures, and immediate feedback.
    • Cognitively undemanding: deals with familiar, routine topics.
    • Typically acquired within 1 to 2 years of immersion.
  2. Cognitive Academic Language Proficiency (CALP):

    • The formal language necessary for academic learning, abstract reasoning, and disciplinary reading.
    • Heavily context-reduced: relies entirely on the printed word or oral lectures with few non-verbal props or external situational cues.
    • Cognitively demanding: features dense informational loads, low-frequency vocabulary, complex syntax (e.g., subordinate clauses, nominalizations), and abstract concepts.
    • Requires 5 to 7 years (and up to 7 to 10 years in non-bilingual, immersion-only settings) to attain parity with native-speaking peers.
DimensionBICS (Conversational)CALP (Academic)
Primary FunctionSocial survival, interpersonal relationships, daily routinesAcademic synthesis, text evaluation, abstract concept acquisition
Timeframe for Mastery1 to 2 years of exposure5 to 7+ years of explicit, sustained instruction
Contextual SupportHigh (context-embedded: gestures, tone, visual environment)Low (context-reduced: print-based, abstract, decontextualized)
Linguistic FeaturesHigh-frequency words (Tier 1), simple syntax, informal registerLow-frequency academic words (Tier 2 & 3), complex syntax, passive voice
Diagnostic RiskHigh risk of false negatives (educators assume student is fully fluent)High risk of misidentification as having a learning disability

[!IMPORTANT] The BICS/CALP Conflation Trap: On the GACE exam, scenario items often describe an English Learner who chats effortlessly with peers at recess and follows conversational instructions, yet struggles significantly with grade-level reading comprehension on informational passages. Novice teachers often assume the student is lazy, unmotivated, or exhibiting a specific learning disability. The Science of Reading identifies this as the classic BICS/CALP discrepancy: conversational ease does not equate to the decontextualized academic literacy required to parse complex expository text.

Common Underlying Proficiency (CUP)

Early deficit views operated on the Separate Underlying Proficiency (SUP) fallacy, assuming that the human brain possesses two isolated language compartments, and that cultivating literacy in L1 diminishes the cognitive space available for L2. Cummins refuted this by establishing the Common Underlying Proficiency (CUP) model:

  • The two languages operate through a shared central processing engine.
  • While the outward surface manifestations (pronunciation, vocabulary, orthographic symbols) appear distinct above the water line, the foundational intellectual and literacy processes below the surface are shared.
  • When a student learns to read in their native language—discovering that symbols represent sounds, that print conveys meaning, that narratives follow structural arcs, and that reading requires metacognitive monitoring—these foundational literacy schemas do not need to be relearned in English.
  • Consequently, strong literacy instruction in a student's native language serves as an accelerant, not an impediment, to English reading acquisition.

4. Cross-Linguistic Phonological & Orthographic Transfer

When Multilingual Learners decode and pronounce English words, they filter the new linguistic system through the phonological and orthographic templates of their primary language. Understanding contrastive linguistic analysis enables educators to differentiate between normal cross-linguistic transfer and true phonological deficits.

Spanish-to-English Phonological & Orthographic Contrasts

Because Spanish is the primary home language for the vast majority of Georgia ESOL students, GACE candidates must master its specific phonological contrasts with English:

  1. The Vowel System Contrast:

    • Spanish possesses a highly transparent, shallow orthography with exactly 5 pure vowel sounds (/a/, /e/, /i/, /o/, /u/), each maintaining a consistent, one-to-one letter-sound correspondence.
    • English possesses an opaque, deep orthography with at least 15 to 20 vowel phonemes, including short vowels, long vowels, diphthongs, and the unaccented neutral vowel schwa (/ə/).
    • Instructional Implication: Native Spanish speakers often struggle to perceive and produce phonemic contrasts between English vowel pairs that collapse into a single Spanish vowel category. Common substitutions include:
      • /ɪ/ (short i as in ship) vs. /iː/ (long e as in sheep)
      • /ɛ/ (short e as in bed) vs. /æ/ (short a as in bad)
      • /ʌ/ (short u as in cup) vs. /ʊ/ (as in book)
  2. Consonant Inventory Differences:

    • English features several consonant phonemes that do not exist in Spanish:
      • Voiced and unvoiced /th/ (/ð/ as in this, /θ/ as in think): Spanish speakers frequently substitute /d/, /t/, or /s/ (e.g., pronouncing think as sink or this as dis).
      • The unvoiced palato-alveolar fricative /sh/ (/ʃ/ as in share): Spanish lacks /sh/ (except in regional dialects), leading speakers to substitute the affricate /ch/ (/tʃ/ as in chair), pronouncing shoes as choes.
      • The labiodental fricative /v/ (/v/ as in vine): In Spanish, letters b and v represent the same bilabial phoneme (/b/ or /β/). Speakers frequently pronounce English /v/ as /b/ (berry for very).
      • The voiced alveolar fricative /z/ (/z/ as in buzz): In Latin American Spanish, letter z is pronounced as unvoiced /s/, leading to substitutions (sip for zip).
      • The voiced affricate /j/ (/dʒ/ as in jump): Frequently substituted with the palatal glide /y/ (/j/ as in yump).
  3. Syllable Structures & Consonant Blends (The Epenthetic /e/ Phenomenon):

    • In Spanish, syllables typically follow an open CV (consonant-vowel) structure. Crucially, no native Spanish word begins with an /s/ + consonant cluster (such as sp-, st-, sk-, sm-, sn-, sl-, sw-). In Spanish, these roots are always preceded by the vowel e (e.g., escuela for school, estudiante for student, especial for special).
    • Instructional Implication: When reading or speaking English words starting with /s/-blends, Spanish speakers naturally insert an epenthetic vowel (/e/), pronouncing stop as "estop", school as "eschool", and spoon as "espoon". This is a predictable phonotactic transfer rule, not an auditory processing disorder or articulation disability.
  4. Orthographic Depth and Morphological Cognates:

    • English and Spanish share extensive Latin and Greek roots. Teachers can leverage cognate awareness to unlock thousands of academic words:
      • Positive Cognates: Family / familia, curious / curioso, hypothesis / hipótesis, photosynthesis / fotosíntesis.
      • False Cognates ("False Friends"): Words that appear identical but hold divergent meanings (e.g., embarrassed does not mean embarazada [pregnant]; sensible in Spanish means sensitive).

| Linguistic Dimension | Spanish (L1) | English (L2) | Diagnostic & Instructional Takeaway | |:---|:---|:---|:---|| | Vowel Sounds | 5 pure, static vowels | 15+ vowel phonemes; extensive diphthongs | Explicitly teach articulatory mouth shapes (mirror work, tongue position) for English short vowels. | | Consonant Sounds | Lacks /sh/, /th/ (voiced/unvoiced), /z/, /v/ | Contains /sh/, /th/, /z/, /v/ | Provide targeted auditory discrimination and tactile phoneme training; do not classify as speech impediment. | | Initial Clusters | Syllables never begin with /s/ + consonant | Frequent /s/ initial clusters (star, speak) | Recognize epenthetic /e/ insertion ("estop") as rule-governed L1 transfer. | | Orthographic Depth | Highly regular, shallow (transparent) | Highly irregular, deep (morphophonemic) | Teach both phoneme-grapheme correspondences and morphemic word roots (prefixes, bases, suffixes). |


5. Sheltered Instruction: The SIOP Model in Structured Literacy

The Sheltered Instruction Observation Protocol (SIOP), developed by Jana Echevarria, MaryEllen Vogt, and Deborah Short, provides an empirically validated framework for making grade-level academic content comprehensible to English Learners while systematically developing their English language proficiency.

The Eight Components of SIOP

  1. Lesson Preparation: Articulating dual objectives: explicit Content Objectives (aligned to Georgia Standards of Excellence) and Language Objectives (specifying the vocabulary, language functions, and syntax students will practice).
  2. Building Background: Explicitly linking new concepts to students' cultural backgrounds, prior life experiences, and past learning, accompanied by pre-teaching critical academic vocabulary.
  3. Comprehensible Input: Adjusting speech rate and enunciation; avoiding colloquial idioms without explanation; utilizing multimodal presentation techniques.
  4. Strategies: Explicitly modeling metacognitive reading strategies (predicting, visualizing, questioning, summarizing) and using scaffolds such as tiered graphic organizers.
  5. Interaction: Structuring intentional peer-to-peer discussions, cooperative learning groups, and collaborative inquiry to maximize authentic language output.
  6. Practice & Application: Integrating hands-on manipulatives, literacy games, and multimodal composing tools that unite reading, writing, listening, and speaking.
  7. Lesson Delivery: Ensuring high student engagement, sustaining focus on both content and language objectives, and pacing instruction to accommodate processing time.
  8. Review & Assessment: Conducting continuous formative assessment of key vocabulary and concepts, providing constructive corrective feedback, and reviewing objectives before concluding.

High-Yield Sheltered Scaffolds for Literacy

  • Realia & Multimodal Visuals: Pairing abstract text with concrete physical artifacts, diagrams, short video clips, and labeled photographs to anchor meaning without relying solely on verbal explanations.
  • Bilingual Glossaries & Word Walls: Organizing cognate walls and bilingual reference charts where academic terms are juxtaposed with native language equivalents and student-generated illustrations.
  • Structured Sentence Frames & Stems: Providing linguistic scaffolding tailored to language proficiency tiers:
    • Beginner (Early Production): The animal is a ________ because it eats ________.
    • Intermediate (Speech Emergence): I predict that ________ because the text states that ________.
    • Advanced (Intermediate Fluency): Although the author claims that ________, the evidence suggests ________ because ________.
  • Structured Language Practice: Incorporating routines like Numbered Heads Together, Think-Pair-Share, and Clock Partners to lower anxiety and ensure all learners rehearse oral academic language before independent reading and writing.

6. Realistic Diagnostic Scenario: The Case of Mateo

Student Diagnostic Profile

Context: Mateo is a 4th-grade student who transitioned to a Georgia public school two years ago from Honduras. In social settings, Mateo appears fully fluent: he converses effortlessly with friends on the playground, jokes with the bus driver, and translates conversational announcements for his parents (demonstrating well-developed BICS).

Assessment Data: On the mid-year universal reading screening (measuring oral reading fluency and expository comprehension on a grade-level history passage about the American Revolution), Mateo performs in the lowest 10th percentile. An analysis of his oral reading errors reveals:

  • He reads special as "especial", state as "estate", and stand as "estand".
  • He mispronounces ship as "sheep" and fit as "feet".
  • He reads valor accurately but cannot define it, despite recognizing valiente (brave) in Spanish.
  • On silent reading comprehension questions requiring inferential reasoning from context-reduced text, he scores 40%.

Teacher Referral: Mateo's novice general education teacher initiates an immediate referral for Tier 3 special education testing, writing in the referral notes: "Mateo has a suspected phonological processing disorder and auditory memory deficit. He cannot decode basic consonant blends, continually mispronounces short vowels, and demonstrates profound reading comprehension deficits despite having fluent spoken English."

Clinical Literacy Analysis & Intervention Plan

The reading specialist reviews the referral and immediately intervenes, identifying classic diagnostic errors:

  1. Misinterpreting L1 Transfer as Pathology: Mateo's pronunciation of "estate" for state is rule-governed phonotactic transfer (Spanish epenthetic /e/ preceding initial /s/-blends). His vowel substitutions (feet for fit) reflect the 5-vowel Spanish inventory mapped onto the complex English system. Neither indicates a phonological processing deficit.
  2. Confusing BICS with CALP: Mateo possesses robust conversational BICS after two years of immersion, but has not yet developed the 5-to-7-year CALP necessary to navigate 4th-grade expository syntax and abstract Tier 2 vocabulary independently.
  3. Unlocking Latent L1 Assets: Mateo possesses solid L1 foundational literacy from early schooling in Honduras. His failure to connect valor to valiente represents an instructional opportunity for explicit cognate training.

Intervention Protocol: Rather than inappropriate special education placement, Mateo is placed in a Tier 2 structured literacy and ESOL intervention group focusing on:

  • Contrastive articulatory phonology (explicit mirror work contrasting English short /ɪ/ and long /iː/, and practicing initial /s/-blends without an epenthetic vowel).
  • Explicit cognate recognition routines bridging Spanish and English academic vocabulary.
  • SIOP-scaffolded graphic organizers and tiered sentence stems for historical texts. Within twelve weeks, Mateo's decoding accuracy rises to 96% and his expository comprehension reaches grade-level benchmarks.

7. Common GACE Exam Traps

  1. The BICS Conflation Trap: Assuming that an English Learner who demonstrates effortless conversational fluency at lunch or recess possesses the academic literacy required to comprehend complex informational text without scaffolds.
  2. The English-Only / L1 Suppression Trap: Choosing answer choices that advise parents to stop speaking their native language at home, or that prohibit students from using bilingual dictionaries or L1 discussions. Research proves that robust native language literacy is the strongest predictor of rapid second-language acquisition.
  3. The Premature Special Education Referral Trap: Selecting options that immediately refer English Learners to special education or speech therapy based on developmental language patterns such as the silent period, epenthetic vowel insertion, or grammatical syntax transfer.
  4. The Simplified Content Fallacy: Confusing linguistic scaffolding with watering down content standards. Sheltered instruction preserves the high cognitive demand of grade-level Georgia Standards of Excellence while providing multimodal access (visuals, realia, sentence frames) to remove linguistic barriers.
