Types of Planning (Ellis, 2005)Types of Planning (Ellis, 2005)

Planning

Pre-task planning

Within-task planning

Rehearsal (task repetition)

Strategic planning

Pressured

Unpressured (on-line planning)

Strategic vs. On-line PlanningStrategic vs. On-line Planning

1. Strategic planning

• Information-processing model

• Skill-learning model

2. On-line planning

• L2 Monitoring (Morrison & Law, 1983)

• Careful within-task planning (Yuan & Ellis, 2003)

Focus-on-Form InstructionFocus-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 learner’s 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)

Page 7: Planning and Focus-on-form in Task- Based Language Learning Ryo Nitta University of Warwick TBLT Conference Leuven, 2005.

Identifying a Link between Planning Identifying a Link between Planning and Focus-on-Formand 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)

Page 8: Planning and Focus-on-form in Task- Based Language Learning Ryo Nitta University of Warwick TBLT Conference Leuven, 2005.

Research QuestionsResearch 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?

Research Hypotheses for Task Research Hypotheses for Task Performance Analysis (1)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.

Page 10: Planning and Focus-on-form in Task- Based Language Learning Ryo Nitta University of Warwick TBLT Conference Leuven, 2005.

Research Hypotheses for Task Research Hypotheses for Task Performance Analysis (2)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.

TaskTask

• 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).

ParticipantsParticipants

• 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.

Page 15: Planning and Focus-on-form in Task- Based Language Learning Ryo Nitta University of Warwick TBLT Conference Leuven, 2005.

FluencyFluency

1. Pruned speech rates2. Mean length of run3. Total length of pauses per minute4. Number of end-clause pauses per 100 words5. Number of mid-clause pauses per 100 words6. Number of filled pauses7. Number of dysfluencies (i.e., false-starts,

reformulation, repetition and self-correction)

Page 16: Planning and Focus-on-form in Task- Based Language Learning Ryo Nitta University of Warwick TBLT Conference Leuven, 2005.

ComplexityComplexity

1. Syntactic complexity: the number of clauses per AS-unit (Foster, Tonkyn and Wigglesworth, 2000)

2. Discoursal complexity: the number of discourse organization devices (Ejzenberg, 2000)

• Chaining integration devices

• Grammatical integration devices

Page 17: Planning and Focus-on-form in Task- Based Language Learning Ryo Nitta University of Warwick TBLT Conference Leuven, 2005.

AccuracyAccuracy

1. Global measures: percentage of error-free clauses (e.g., Foster & Skehan, 1996)

2. Specific measures:• Percentage of target-like verb forms (Yuan & Ellis,

2003)• Percentage of target-like article (Crookes, 1989)

Page 18: Planning and Focus-on-form in Task- Based Language Learning Ryo Nitta University of Warwick TBLT Conference Leuven, 2005.

Factor AnalysisFactor 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.
