Roy LysterOral corrective feedback as a catalyst for
second language development
This was the evening plenary of the first day of the 1st International Conference on Written Corrective Feedback, held at the University of Vic, Catalonia, 14th April, 2023.
Roy Lyster is Professor Emeritus of Second Language Education at McGill University in Montreal (Canada). He is best known in the field of language teaching education for his work on corrective feedback and learner uptake, e.g. Lyster & Ranta, 1997.
Complementary
approaches to L2 teaching
Professor Lyster explained that the vast majority
of his research, training and indeed his own teaching has taken place in an EMI
(English as Medium of Instruction) context in bilingual education in Canada (=
CLIL in Europe). Based on his extensive observations of ELT in these classes,
he suggests that effective L2 teaching should use these two approaches in
tandem:
Proactive approach |
Consists of planned content-based or meaning-oriented instruction designed
to meet curricular objectives while fostering language use and language
awareness |
Reactive approach |
Ensures that oral interaction is a key source of
language learning though scaffolding techniques such as teacher questions and
corrective feedback |
To
correct or not to correct?
Errors are a part of learning and indicate
that learners are formulating and testing their hypotheses about the target
language. However, in order to make sure learners benefit from this trial and
error, these hypotheses need to be confirmed or dismissed. In other words, they
need corrective feedback (CF)
CF has an essential scaffolding role, because it allows teachers to provide language support during meaningful interaction. There is a large body of research to support the effectiveness of oral corrective feedback (OCF), including at least four meta-analyses, e.g. Mackey & Goo, 2007. Basically, providing correction helps!
Teachers are understandably reluctant to interrupt the oral interaction of learners making an effort to talk in order to provide immediate error correction. Furthermore, teaching manuals and training courses generally discourage intervention during fluency activities in favour of noting errors and providing delayed corrective feedback (DCF) after the activity has concluded. However, Lyster & Ranta (1997) found that none of the feedback types (see below) disrupted the flow of interaction. On the contrary, students expected to be corrected and were not frustrated by it.
Types of oral corrective feedback
CF can be explicit – you tell the student
you are correcting them and provide the correct version, or implicit – the
learner has to do the work, noticing and/or producing the correct version. The implication
is that the more work the student does (Depth of Processing), the more
memorable it is and more learning occurs.
There are two families of OCF:
·
Those which provide the correct
form: Reformulations. These are explicit correction (e.g. no – don’t say
that, say this) and implicit - recasts
(repeating the learner’s utterance correctly before continuing with the next
conversational move)
·
Those which withhold the
correct form: Prompts. These ‘push’
the students to self-repairs. They are receiving feedback and producing output (Swain, 2005). These include: clarification requests; metalinguistic
clues, elicitation, repetition of error.
Teachers
love recasts
In their observations of French immersion
classes, Lyster and Ranta found that well over half of CF episodes were recasts.
There are good reasons for this. They preserve the student’s original meaning and move the conversation along naturally. Also, if noticed, they free up the learner’s attentional resources (Long, 1996). Teachers justify their use of recasts as a way of correcting students without embarrassing them in front of others. However, this contradicts the message that ‘It’s OK to make errors, it’s a normal part of learning’. Also, in order to be effective, the recasts need to be noticed as CF. Students may interpret them differently!
What
do teachers need to know?
Lyster believes that teachers need to be
aware not only of the types of OCF they can provide, but also of the learners’
responses following the feedback. These responses (uptake) basically fall into
two categories: learner repair or utterances still in need of repair. This
uptake provides an indication of the learner’s current level of performance.
This is particularly important in contexts where ‘dynamic assessment for
learning’ is used to monitor students’ current levels in order to ‘push’ them
to the next level (e.g. Lantolf & Poehner, 2010)
“ The purpose of OCF is not only to provide students with information about accuracy but also the means for them to move towards more advanced levels of performance” (emphasis in original)
In praise of prompts
Lyster argues that prompts are more
effective: they help students to notice errors and generate correct forms. Also,
learners remember information better when they take an active part in producing
it rather than having it provided for them by an external source. He recalls an
instance in his own teacher training when he was told that under no
circumstances should a teacher repeat a student error as it may be interpreted
as the correct form. However, learners are intelligent enough to pick up the
intonational and non-verbal clues that a teacher uses when repeating an error
as a prompt.
We watched two short videos of classroom
interaction (same teacher, same pupils, grade 5 in an English immersion
programme for L1 French speakers). The class was content-based and
meaning-focused, discussing a class reader. In the first, the teacher used
recasts and the interaction moved along effectively. In the second, the teacher
used a variety of prompts, and Lyster highlighted the affordances that these
provided (see his comments on the transcript below)
He pointed out that some of the most effective teaching he had observed over the course of his career was when a teacher ‘smartly played dumb’.
Implications for teacher training
In their seminal paper on classroom
discourse, Sinclair and Coulthard (1975) identified the most typical classroom
questioning exchange, consisting of three moves:
Initiating (I) move by the teacher Responding (R) move by the learner Evaluative (E) by the teacher |
T: What would Max be feeling? S: He would be very worried T: Yes, very worried. That’s a really good word. (Tedick
& Lyster, 2020) |
This IRE pattern generally concludes with a teacher move which effectively shuts down the interaction. Teachers can be trained to ask follow-up questions to scaffold continued discourse.
Furthermore, as research has not yet
provided conclusive evidence in favour of indirect v direct or comprehensive v
selective correction (either in oral or written corrective feedback), this
effectively leaves the door open for teachers to use a variety of feedback
types according to their specific language learning objectives.
Prof. Lyster concluded his presentation by
appealing to teachers to use the repertoire of techniques available to them,
and to reconsider our fondness for recasts
