What is Language? Education 388 Lecture 3 January 23, 2008 Kenji Hakuta, Professor Learning Objectives General: This class is meant to address student knowledge about language and linguistics (the formal study of the nature of language) in particular as they apply to ELL teaching. Specific Objectives: STUDENTS WILL be able to…. • • • • • State that language consists of sounds, words, sentences, meanings, and social uses; that different languages vary on these dimensions. Apply knowledge about language to the analysis of language errors found in their ELL students. State why the analysis of language has caused controversy about how related areas such as reading and writing are taught in the schools. State a biological and a linguistic argument for why second language acquisition is complex and must take into account the characteristics of the learner. Apply the theories about language to the analysis of the California (and other) state English Language Development standards.

Second Language Errors • A “language error” is a systematic variation in form from the standard language that occurs in the speech or writing of second language learners. “He no like his job” contains a language error (“no” rather than “doesn’t”) if it occurs consistently. It may or may not be attributable to the speaker’s native language. It is not random; rather, it is predictable on the basis of linguistic principles. • Can you think of an example of language errors that you have observed in your students? Some Examples of English Grammatical Difficulties (based on Robin Scarcella) Verb Forms • I always remembered when my friend died. • I study English since 1986 Prepositions – often absent or used incorrectly • The nucleus is on the cell. • He discriminate me. Articles – often absent or used incorrectly. • The knowledge is good. • On first day school I get loss. Count/non-count nouns • The T.A. gave me many good advices. • I read the informations.

Analysis of Language • • • • • • • • • Subfield of lingusitics / the study of _______ Phonetics / sounds Phonemics / phonemes Morphology / morphemes Lexicology / words Syntax / grammar Semantics / meaning Pragmatics / social uses Sociolinguistics / social variation Components of Language and Reading • Phonemic Awareness: The ability to hear and manipulate sounds in words. • Alphabetic Principle: The ability to associate sounds with letters and use these sounds to form words. • Fluency with Text: The effortless, automatic ability to read words in connected text. • Vocabulary: The ability to understand (receptive) and use (expressive) words to acquire and convey meaning. • Comprehension: The complex cognitive process involving the intentional interaction between reader and text to convey meaning. Source: http://reading.uoregon.edu/ Categorical Speech Perception • The human speech (language) recognition system is finely tuned, and creates categorical perception out of continuous information. • Research on categorical speech perception is the strongest evidence (perhaps) of the modularity of language (see Pinker). • There are language-specific aspects to this: the /ba/ to /pa/ continuum is marked differently in English and in Spanish. Language Functions and Modalities are Localized in the Brain Different Tasks are Localized Too Hearing Speaking Thinking about Source: National Institute of Aging www.nia.nih.gov/Alzheimers/Resources/HighRes.htm McGurk Effect: A vivid demonstration of sensory integration. • The same sound, e.g., /ba/ is perceived differently depending on visual cues about vocal production (place of articulation) – you will hear it as /ba/ or /da/ depending on what you see. • View the effect: http://www.youtube.com/watch?v=73LE1vKGfy4&feature=related • On Japanese TV!
