Recasts in the ESL classroom: Comparing the effectiveness of different types of corrective feedback Jenefer Philp & Shawn Loewen University of Auckland, New Zealand
Recasts • Target-like reformulations following a learner’s non-TL utterance. • Maintains the central meaning, while changing elements of the form (lexical, morphological, syntactic, phonological components). (Long, 1996)
Example 1 (Loewen 2002) Kao: his crime was uh when he was uh seventeen uh he over drunk he drank too much and get fight with some boy and the boy uh get got into unconscious T: became unconscious Kao: became unconscious and permanently damaged his brain
Example 2 (Philp, 1998) NNS why why is the why is he why is the son read read the table? NS why is he ah setting the table? NNS uh huh
Features of recasts • Provides implicit negative feedback • Juxtaposes the learners’ incorrect utterance with the target-like version • Contingent on the learner’s production • Incidental
Corrective feedback in the L2 classroom • Elicitation moves : repetition, clarification requests, prompts • Informs: explicit correction • Recasts
Recasts in the classroom • Impact of context (Morris & Tarone, 2003; Seedhouse, 1997; van Lier, 1988) • Range in explicitness and salience (Nicholas, Lightbown & Spada, 2001; Ellis, to appear)
Salience and response moves 1.Ph driver 2.T a driver did you say? 3.Ph screw screw driver 4.T what’s a school driver? Screwdriver 5.Ph screwdriver 6.T a screwdriver 7. Ph screwdriver 8. T yeah I think I’d call that a tool that’s that’s not an appliance it’s not powered by electricity
1.T: you have to tell this story to Jack okay not your story you’re telling the story “girl had bullet in her scalp”. 2.S: the title of the story is girl had blood in her scalp 3.T: blood? 4.S: bloot 5.T: bullet bullet= 6. S: =bullet bullet in her scalp is about is about
Prosodic emphasis (stress) 1.H: some people have racism 2.T: some people ARE racist 3.H: are racist
Segmentation 1.Thom: yeah and uh when they went to the ban the gateway and they stu- stu- in 2.T: got stuck 3.Thom: got stuck on the rova, ro:
Intonation • Declarative recast • Interrogative recast (Lyster 1998; Sheen 2004)
Are recasts beneficial? • Juxtaposition of the correct with the incorrect • Congruent with the learner’s production • Maps meaning to form • Incidental & transitory (Doughty, 2001; Long, to appear; Philp, 1998)
If noticed… • Noticing is crucial (Gass, 1997; Mackey, in press; Philp, 1998; Schmidt, 1993, 2001) • Recasts may help learners ‘notice the gap’
Potential limitations of recasts • Ambiguous • Learners are not pushed in their output • Differentially beneficial depending on form • Other forms of feedback may be more beneficial (Ellis, to appear; Lyster, 1998, 2004; Lyster & Ranta, 1997; Panova & Lyster, 2002)
Research Questions • Description of recasts in the L2 classroom • Effectiveness of recasts (post tests / successful uptake) • Differences between recasts and effects on test performance / successful uptake
Data (Loewen, 2002) • 17 hours of classroom interaction • 12 ESL classrooms • 118 adult intermediate-level learners • Tailor-made tests 1-3 days and 2 weeks later
TEST: Correction Example The following sentences are incorrect or inappropriate. Please listen and tell me how you could make the sentences better. 1. I used to wear the balaclava for protection to wind and cold. S: when I was soldier I used to wear the balaclava T: and why did you wear it S for protection from the cold or for another reason S: just wind uh protection to wind and cold T: protection from S: uh from wind and cold T: right, okay not for a disguise
Test: Pronunciation • Learners were asked to first read aloud a sentence containing the targeted word/phrase and then to read aloud the target word/phrase in isolation.
Coding of data • Type of feedback move • Recasts: segmentation, stress, length, number of changes, complexity and intonation • Uptake: successful uptake, no uptake, no chance • Test performance: correct, incorrect
Recall on Post Test • Learners were able to recall at least 50% of test items • No significant differences in learners’ ability to recall correctly on the tests and they type of feedback they had received. • Post test: Chi square (2, 180) p =.114 • Delayed post test: Chi square (2, 188) p = .577
Successful Uptake • Recasts resulted in high levels of successful uptake (72.6%) • Elicitation moves associated with significantly higher numbers of successful uptake (88.3%) • Informs associated with significantly higher levels of Unsuccessful uptake • Chi square (2, 363) = 16.63, p<.001
Successful uptake and test performance (Logistic regression) • Successful uptake predicted by : Stress 13.235 .000 Complexity 5.052 .000 Intonation .351 .014 Number of changes .519 .068
Recasts and test performance (Logistic regression) • Correct and partially correct test scores predicted by : Morpheme Length .509 .149 Intonation 2.206 .084 Number of changes .519 .068
Summary • 50% of corrective feedback moves are recasts. • High levels of successful uptake, with 88% for elicitation moves. • No significant difference between teachers’ response moves and performance on tests. Recasts were associated with 50% success rate.
The majority of recasts in these ESL classrooms were: • Short • Stressed More • Declarative Explicit • Segmented
Recasts and Successful Uptake • Stress • >1 response move successful uptake • One change • Falling intonation
Recasts and Post Test Recall • Rising intonation • Shorter recasts recall on post tests • One change
