Foundations of Language and Language Acquisition
This domain is tested through items on phonology, morphology, syntax, semantics, and pragmatics, plus the major first- and second-language acquisition theories. The exam expects you to see learner English as a rule-governed system rather than as carelessness, and to match a theorist or theory to the classroom decision it justifies.
Language as a system
- Phonology: learners filter incoming sounds through their L1 phoneme inventory, so a Spanish-speaking student may hear ship and sheep as one word, and consonant clusters (/str/) get simplified.
- Morphology: free vs. bound morphemes; inflectional affixes (-ed, -s, -er) vs. derivational affixes (un-, -ness). Languages such as Mandarin that do not inflect verbs for tense leave English tense endings as a predictable trouble spot.
- Syntax and semantics: word order, articles, question formation, polysemy, idioms.
- Pragmatics: register, politeness, turn-taking, and how context shifts meaning - the layer content classrooms most often neglect.
Acquisition theory
- Krashen: comprehensible input (i + 1), a low affective filter, natural order; conscious learning does not automatically become acquisition.
- Cummins: BICS roughly 2 years, CALP 5–7 years - why a student can chat comfortably yet stall on a textbook chapter.
- Interlanguage (Selinker): errors reveal an internal rule system. Overgeneralization (goed) and L1 transfer are different diagnoses with different responses.
- Vygotsky (ZPD, scaffolding) and Long (interaction/negotiation of meaning) explain why structured pair work produces growth.
Worked example
A fourth grader writes, Yesterday I goed to the store. The learner has already internalized the regular past-tense rule and applied it too widely: this is overgeneralization, a developmental step, not an L1 habit and not laziness. The teacher recasts - Oh, you went to the store - restating the target form inside meaningful talk and letting the developmental sequence continue, rather than drilling the irregular list in isolation.
Traps that cost marks
- Labeling every error L1 interference, when many are developmental.
- Confusing phonemic awareness (identity of sound units) with phonics (letter–sound correspondences).
- Reading BICS fluency as grade-level academic proficiency.
