Stephen Krashen: Learning vs. acquisition Natural order Monitor Input (I + 1) Affective filter Second Language Acquisition © 2014 MARY RIGGS 2

Jim Cummins: Linguistic threshold Degree of L1 proficiency Effects of student status Context and cognitive load Dimensions of proficiency: Iceberg Common underlying proficiency Effects of prior literacy Second Language Hypotheses © 2014 MARY RIGGS 3
4
Other Significant Hypotheses: 2-way interaction: display vs. referential questions (Long) Acculturation (Schumann) Critical vs. sensitive period (Lenneberg and others) Optimal age for 2LA (Collier & Thomas) Older = better Diminishing returns for LOR Second Language Hypotheses © 2014 MARY RIGGS 4

Learning vs. Acquisition Learning: Grammar-based syllabus Mastery of linguistic forms Conscious memorization Drills and exercises Teacher-directed Contrastive analysis Error correction Production skills emphasized Acquisition: Syllabus based on students needs, desires, interests Developmental emphasis Communicative goals Subconscious internalization Student-centered Errors not overtly corrected Comprehension skills emphasized © 2014 MARY RIGGS 10
11
Acquiring a Second Language Ineffective Practices: Sentence patterns out of context Drills, discrete repetitions Watered-down, boring stories Grammatical analysis Frequent correction of all errors Judgmental attitude Assumption that all learners can/will react the same way Effective Practices: Comprehensible input that is relevant and interesting Visuals, gestures, realia Challenging questions/stories Interaction on real-world tasks Response to content of student responses/writing Tolerance and sense of humor Sensitivity to cultural difference © 2014 MARY RIGGS 11

Stages of Acculturation © 2014 MARY RIGGS 12

2.Culture Shock: effects ranging from irritability to physiological and psychological panic and crisis: Anger, annoyance at others inattentiveness, constant complaining, disorientation, dissatisfaction, escapism, estrangement, frustration, homesickness, indecision, insecurity, loneliness, physical illness, resentment, sadness, self-pity, self-questioning of competence, social uncertainty Stages of Acculturation © 2014 MARY RIGGS 13

3.Culture stress: progress is made but individual may feel anomie, the sense that one belongs to neither culture. 4.Acculturation or assimilation: near or full recovery Stages of Acculturation © 2014 MARY RIGGS 14

1.Display Question: In what year did Columbus arrive in the New World? (Everyone knows the teacher knows the answer to this; the student must display his/her knowledge.) 2.Referential Question: If you had sailed with Columbus, what sort of job would you have had on the ship? (No one knows what answer the student might give; the instructional conversation is open-ended.) Two-Way Interactions © 2014 MARY RIGGS 16
