3.2 Emergent Bilinguals, Cross-Language Transfer, & Texas ELPS

3.2 Emergent Bilinguals, Cross-Language Transfer, & Texas ELPS

The Legal and Pedagogical Mandate: Texas ELPS

In Texas public education, meeting the linguistic and academic needs of Emergent Bilinguals (English Learners) is a shared statutory responsibility codified in the Texas English Language Proficiency Standards (ELPS) under 19 TAC Chapter 74.4. The ELPS mandate that all teachers—regardless of content area or grade level—must provide content-area instruction that is linguistically accommodated (communicated, sequenced, and scaffolded) commensurate with the student's levels of English language proficiency.

The ELPS outline proficiency level descriptors across four distinct language domains: Listening, Speaking, Reading, and Writing. Texas educators must assess student growth annually through the Texas English Language Proficiency Assessment System (TELPAS) and systematically tailor daily oral language tasks to advance students across four developmental tiers.

The Asset-Based Framework & Common Underlying Proficiency

Texas STR pedagogy operates strictly from an asset-based perspective toward bilingualism. An asset-based framework views a student's home language ($L1$) not as an impediment or deficit to be eradicated, but as a rich cognitive and linguistic foundation that accelerates English ($L2$) literacy. This framework embraces additive bilingualism, in which English literacy is added to primary-language literacy without degrading the native tongue.

Dr. Jim Cummins conceptualized this relationship through the Common Underlying Proficiency (CUP) model, widely known as the "Dual Iceberg Hypothesis."

          SEPARATE SURFACE FEATURES (L1 & L2)
   Spanish Oral / Print              English Oral / Print
         ▲         ▲                       ▲         ▲
         │         │                       │         │
─────────┼─────────┼───────────────────────┼─────────┼────────── [Surface Level]
         │         │                       │         │

                               ▼
                  COMMON UNDERLYING PROFICIENCY
                   (Cognitive Academic Concepts,
                   Linguistic Schemas, Phonemic
                    Awareness, Metacognition)

While the surface features of two languages (specific alphabets, phonetic pronunciations, grammatical syntax) appear entirely separate above the surface, they are fed by a single, shared cognitive-linguistic reservoir beneath the water line. When an emergent bilingual student learns a concept in their primary language—such as understanding that plants require photosynthesis, or mastering the metacognitive process of chronological sequencing—they do not need to re-learn that underlying cognitive concept in English. They merely require the English phonetic labels, academic vocabulary, and syntactic sentence structures to express their existing knowledge.

Cross-Linguistic Transfer: Positive vs. Negative

Cross-linguistic transfer occurs when knowledge, skills, or linguistic habits established in $L1$ influence performance in $L2$. Teachers must systematically distinguish between positive transfer (facilitating literacy) and negative transfer (interference requiring targeted contrastive analysis).

Positive Cross-Linguistic Transfer

1. Phonological Awareness Transfer: Foundational phonological skills mastered in $L1$—such as syllable segmentation, rhyming, and phonemic manipulation—transfer directly to English. A student who can isolate phonemes in Spanish does not need to re-learn the abstract concept of phonemic segmentation in English.
2. Concepts of Print: Understanding print directionality (left-to-right, top-to-bottom), book handling, punctuation functions, and the alphabetic principle transfers completely between alphabetic languages.
3. True Cognates: Words in two languages that share common Greek or Latin etymological roots, similar spellings, and identical meanings. Over 30% to 40% of English vocabulary words have direct Spanish cognates, representing a massive cognitive bridge for emergent bilinguals.

Negative Cross-Linguistic Transfer (Interference)

1. False Cognates (Falsos Amigos): Words that appear visually similar in both languages but carry fundamentally different definitions, generating acute comprehension errors.
2. Phonological Discrepancies: Spanish contains only five pure vowel sounds (/a/, /e/, /i/, /o/, /u/), whereas English features more than 15 distinct vowel phonemes, including short vowels (/ɪ/, /æ/, /ʌ/, /ʊ/) and r-controlled vowels. Spanish-speaking emergent bilinguals predictably substitute familiar pure vowels for English vowel phonemes (e.g., pronouncing ship as sheep or cut as cot).
3. Syntactic and Word Order Differences: In Spanish, descriptive adjectives typically follow the noun (el carro rojo), whereas English requires pre-nominal adjective placement (the red car). Additionally, Spanish allows pronoun omission because verb conjugations encode the subject ("Es grande" vs. English "It is big").

Foundational Second Language Acquisition Theories

Stephen Krashen's Second Language Acquisition Hypotheses

1. Comprehensible Input Hypothesis ($i + 1$): Language is acquired when learners receive linguistic input that is slightly beyond their current level of proficiency ($i$), made comprehensible through context, visuals, gestures, and background knowledge ($+1$). If input is at level $i + 0$, no acquisition occurs; if at $i + 2$, input is incomprehensible noise.
2. Affective Filter Hypothesis: Emotional and psychological variables—such as high anxiety, low self-efficacy, and fear of public embarrassment—act as an invisible cognitive barrier (the "affective filter") that blocks comprehensible input from reaching the brain's language processing centers. To optimize acquisition, teachers must create low-stress, emotionally safe classrooms.
3. The Silent Period: A natural, developmental stage in early second-language acquisition where the learner focuses entirely on receptive comprehension before attempting expressive speech. Forcing an emergent bilingual in the Beginning proficiency level to speak prematurely spikes their affective filter and retards language growth. Teachers must honor the silent period by allowing non-verbal demonstrations of comprehension (e.g., pointing, gesturing, matching pictures).

Jim Cummins: BICS vs. CALP

Dr. Jim Cummins established a critical distinction between two fundamentally different types of language proficiency:

1. BICS (Basic Interpersonal Communicative Skills):
   • Context-Embedded: High reliance on paralinguistic supports, gestures, facial expressions, and concrete realia.
   • Developmental Timeline: Typically acquired within 1 to 3 years of exposure to English.
   • Functional Context: Playground interactions, cafeteria discussions, social hellos, and informal phone conversations.
2. CALP (Cognitive Academic Language Proficiency):
   • Context-Reduced & Cognitively Demanding: Relies almost exclusively on linguistic text without environmental props; features abstract, specialized Tier 2/3 vocabulary and complex syntactic structures.
   • Developmental Timeline: Typically requires 5 to 7+ years (and up to 10 years without native-language schooling) to reach grade-level parity with native English peers.
   • Functional Context: Reading science textbooks, analyzing historical primary sources, writing argumentative essays, and taking standardized assessments.

THE BICS / CALP ICEBERG MODEL
======================================================
    BICS (1–3 Years)               CALP (5–7+ Years)
    Context-Embedded               Context-Reduced
    Cognitively Undemanding        Cognitively Demanding
    [Social / Conversational]      [Academic / Textual]
------------------------------------------------------
• Playground discourse             • Science lab reports
• Cafeteria interactions           • STAAR reading passages
• Informal greetings               • Synthesizing evidence
• Video game chats                 • Mathematical word problems
======================================================

The Diagnostic Trap: A pervasive error among novice educators is observing an emergent bilingual student chatting fluently with peers on the playground (high BICS) and incorrectly concluding that the student has attained complete English proficiency. When that same student struggles to comprehend a grade-level expository text, the teacher erroneously suspects a learning disability. Educators must recognize that BICS does not equal CALP!

Real Classroom Scenario: ELPS Scaffolding in Science

Ms. Garza teaches a third-grade inclusive science class containing four emergent bilingual students at the Intermediate level of English proficiency. During a lesson on plant adaptations, Ms. Garza avoids lecturing abstractly from the textbook. Instead, she implements research-based ELPS accommodations:

1. Comprehensible Input ($i + 1$): She introduces real cacti, desert soil, and large diagrams displaying clear arrows. She uses gestures to mimic thick plant walls holding water.
2. Cognate Bridge: She highlights that the English word adaptation is a cognate for the Spanish adaptación, and photosynthesis is fotosíntesis.
3. Structured Sentence Frames: To support expressive oral output and lower the affective filter, she provides paired sentence frames:
   • Level 1 Frame: "The cactus survives in the desert because it has _________."
   • Level 2 Frame: "Although water is scarce in the desert, the cactus adapts by _________, which allows it to _________."
4. Structured Partner Rehearsal: Before any student is asked to share orally with the whole class, they practice with a partner, ensuring a low-anxiety oral trial.

As a result, her Intermediate students successfully articulate complex scientific conclusions using academic English without feeling intimidated or silenced.
