2Introduction
- Two research traditions in SLA planning and
focus-on-form - The study analysis of task performance and
verbal protocols - Findings of task performance analysis
- Implications
- Issues for the second stage
3Types of Planning (Ellis, 2005)
Rehearsal (task repetition)
Pre-task planning
Strategic planning
Planning
Pressured
Within-task planning
Unpressured (on-line planning)
4Strategic vs. On-line Planning
- Strategic planning
- Information-processing model
- Skill-learning model
- On-line planning
- L2 Monitoring (Morrison Law, 1983)
- Careful within-task planning (Yuan Ellis, 2003)
5Summary of the Previous Research
6Focus-on-Form Instruction
- The noticing issue Do learners have the
cognitive resources to notice the gap between
their IL utterances and the TL utterances around
them? - The interruption issue Is a pedagogical
intervention that does not interrupt the
learners own processing for language learning
even possible? - The timing issue If so, then precisely when,
in cognitive terms, should the pedagogical
intervention occur? (Doughty, 2001)
7Identifying a Link between Planning and
Focus-on-Form
- Theoretical issue Strategic planning facilitates
a learner-driven focus-on-form (Ortega, 1999,
2005) - Methodological issue A process-product approach
to planning. How do L2 learners plan during
strategic planning time? (Ortega, 1999, 2005
Sangarun, 2005)
8Research Questions
- Do different planning conditions differently
influence the oral performance? - How do L2 speakers plan their speech on-line when
their performance is underway? Do they focus on
form in on-line planning more frequently than
strategic and no-planning conditions?
9Research Hypotheses for Task Performance Analysis
(1)
- Hypothesis One Strategic planning (SP) will give
more positive influence on fluency, complexity
and accuracy than no-planning (NP). - Hypothesis Two On-line planning (OP) will give
more positive influence on complexity and
accuracy, but more negative influence on fluency
than NP. - Hypothesis Three OP will give more positive
influence on complexity and accuracy, but more
negative influence on fluency than SP.
10Research Hypotheses for Task Performance Analysis
(2)
- Hypothesis Four The effects of SP will interact
with the different proficiency levels. - Hypothesis Five The effects of OP will interact
with the different proficiency levels.
11Research Design
12Task
- Story-telling tasks x 3 6 picture cartoons taken
from a popular story-telling resource book for
EFL learners (Heaton, 1975). - Different, but clearly structured tasks (cf.
Tavakoli Skehan, 2005) - The first obligatory sentence was given to
encourage the use of past tense forms in each
task, following Ellis (1987).
13Task Implementation
14Participants
- 27 Japanese speakers of English (male 11,
female 16) - Length of residence mean 11.86 (months), SD
13.74, Range 0.25 (i.e., 1 week) - 41.00 (i.e.,
3 years and 5 months) - High vs. Low Proficiency 6-point global ratings
by three raters to judge the NP speech. The
average scores were used to categorize high and
low proficient groups.
15Fluency
- Pruned speech rates
- Mean length of run
- Total length of pauses per minute
- Number of end-clause pauses per 100 words
- Number of mid-clause pauses per 100 words
- Number of filled pauses
- Number of dysfluencies (i.e., false-starts,
reformulation, repetition and self-correction)
16Complexity
- Syntactic complexity the number of clauses per
AS-unit (Foster, Tonkyn and Wigglesworth, 2000) - Discoursal complexity the number of discourse
organization devices (Ejzenberg, 2000) - Chaining integration devices
- Grammatical integration devices
17Accuracy
- Global measures percentage of error-free clauses
(e.g., Foster Skehan, 1996) - Specific measures
- Percentage of target-like verb forms (Yuan
Ellis, 2003) - Percentage of target-like article (Crookes, 1989)
18Factor Analysis
- On the whole, the results of three factor
analyses represent three independent dimensions,
fluency, complexity and accuracy. - Mean length of run was selected for MANOVA
analysis as a fluency component. - The number of grammatical integration devices was
selected as a complexity component. - The percentage of error-free clauses was selected
as an accuracy component.
19Repeated measures MANOVA
20Univariate test of within-participant effect
21ANOVAs in Two Proficiency Groups
22Specific Accuracy Measures
23Implications
- Trading-off between fluency and form
- Fluency and accuracy
- Fluency and complexity
- Interaction between fluency and proficiency
- Monologic story-telling task type?
- Dual mode?
- Interaction between accuracy and proficiency
- Form-focused effects of on-line planning
24Next Stage
- To identify the mental operations in the three
planning conditions. - To identify different mental operations between
high and low proficient speakers. - Strategic planning ? High proficient speakers
- On-line planning ? Low proficient speakers
