Title: Planning and Focusonform in TaskBased Language Learning


1
Planning and Focus-on-form in Task-Based Language
Learning
  • Ryo Nitta
  • University of Warwick
  • TBLT Conference
  • Leuven, 2005

2
Introduction
  • 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

3
Types of Planning (Ellis, 2005)
Rehearsal (task repetition)
Pre-task planning
Strategic planning
Planning
Pressured
Within-task planning
Unpressured (on-line planning)
4
Strategic 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)

5
Summary of the Previous Research
6
Focus-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)

7
Identifying 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)

8
Research 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?

9
Research 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.

10
Research 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.

Research Design
12
Task
  • 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).

13
Task Implementation
14
Participants
  • 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.

15
Fluency
  • 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)

16
Complexity
  • 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

17
Accuracy
  • 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)

18
Factor 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.

19
Repeated measures MANOVA
20
Univariate test of within-participant effect
21
ANOVAs in Two Proficiency Groups
22
Specific Accuracy Measures
23
Implications
  • 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

24
Next 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
