The Influence of Choice The Influence of Choice Upon Complex Output in Upon Complex Output in TBLTTBLTJohn ThurmanHokkaido University3rd Biennial International Conference on Task-Based Language Teaching13-16 September 2009Lancaster University
The QuestionThe QuestionWill a method of increasing students’
interest in conducting a task, that of the introduction of topic choice, have an effect upon the complexity of the oral output of the students?◦The introduction topic choice has shown
to improve participants’ interest in conducting a language learning task (Thurman, 2008), intrinsic motivation (Zuckerman et al, 1978), vigilance (Dember et al, 1992), and to reduce anxiety (Stotland & Blumenthal, 1964).
Complexity in TBLTComplexity in TBLTConcerns the cognitive demands of
a task and the attentional resources that students utilize during a task
Highly Important.◦AILA 2008
Often a central area of research (e.g., Gilabert, 2007), such as in Skehan’s (2007) Trade-off and Robinson’s (2007) Cognition models of language acquisition.
Complexity . . .Complexity . . .Indicates change and
development in the interlanguage system.
Is based on the ability of learners to take risks and use more language subsystems with the possibility that such language may not be controlled effectively.
Is how advanced (i.e., subordinated) the language is.
Complexity . . .Complexity . . .Concerns cognitive factors
affecting students’ cognitive challenge:◦Resource-directing: Demands which
direct learner attention and effort in using the L2 system.
◦Resource-dispersing: Demands which increase task complexity without directing learner attention and effort to any particular aspects of language code (i.e., planning).

ConclusionsConclusionsThe descriptive task seemed to be
the most salient with statistically significantly greater increases of words-per-turn (interactional complexity), subordination (grammatical complexity), and Guiraud’s Index (lexical complexity).
Task affect (Interest or time-on-task) was mixed but higher for both types of tasks.
WHAT IS THE WHAT IS THE MOTIVATIONAL BASIS MOTIVATIONAL BASIS OF TBLT?OF TBLT?
Food for Thought
Affect in TBLTAffect in TBLTSome researchers in the TBLT
field claim that task-based language teaching is more motivating, compared to the more traditional (i.e., P-P-P) methods.
Why is TBLT more motivating?
Affect in TBLTAffect in TBLTDornyei (2002) found that the pooled
scores of the pairs of course attitude and task attitude correlated significantly with the number of words produced by the pairs and the number of turns by the pairs (Table 5).◦In this study, there were no significant
correlations of Task Interest nor Time on Task with any of the dependent variables for either the descriptive task or the narrative task (limited choice treatments only).
Affect in TBLTAffect in TBLTGilabert (2007) found that
students had significantly higher stress with a There-and-Then narrative task, as compared to a Here-and-Now narrative task, and significantly higher confidence with the Here-and-Now task, but there were no differences for interest or motivation between the two types of tasks.
Affect in TBLTAffect in TBLTThere has been the claim that
The Attribution Model of motivation (Skehan, 1989) may be a motivational basis in TBLT*◦The reason for this was that students
would attribute success to their skill or knowledge more in the TBLT environment, as compared to luck.
*The claim was not made by Skehan.
Affect in TBLTAffect in TBLTIt is my belief that the motivational
basis of TBLT may be the Self-Determination Theory (SDT) of human motivation◦In tapes, students would at times be
surprised as to how well they did on the task and in using English (i.e., competence)
◦There is a great deal of autonomy in TBLT. Even though there may be focused tasks (Ellis, 2003), students still have the autonomy as to where to start and which language to use.
How well does the How well does the motivational basis of TBLT motivational basis of TBLT relate to a new model of relate to a new model of language learning language learning motivation?motivation?
The L2 Motivational Self The L2 Motivational Self SystemSystemDeveloped in Dörnyei (2009) based
on the theory of ideal self and ought-to self by Markus and Nurius (1986).◦The ideal self refers to the attributes
that one would ideally like to posses. Includes integrative and internalized
instrumental motivations.◦The ought-to self refers to the attributes
one believes one ought to posses. Includes the more extrinsic types of
instrumental motives.
A Link Between SDT and the A Link Between SDT and the L2 Motivational Self SystemL2 Motivational Self SystemNoels (2009) maintains that SDT, with
its levels of internalisation of engaging in an activity, from extrinsic motivation to intrinsic motivation, underscores the central role of the self in language learning and that SDT is closely aligned with the L2 Motivational Self System.
Lynch et al (2009) found that the support of autonomy was related to lower ideal self- and actual self-concept* discrepancies.
*Aspects of the self-concept deemed acceptable “determined by the nature of one’s interactions with others.”
TBLT and the L2 Motivational TBLT and the L2 Motivational Self SystemSelf SystemIt is intuitively intriguing that TBLT,
with its design of the tasks that fosters actual language use, with its implementation features that fosters autonomy for the students, and with its syllabus designed to meet the needs of the students, will promote the L2 Motivational Self System.
Future research combining L2 Motivational Self System research methodology and TBLT could prove to be insightful in linking a teaching methodology and a motivational theory in the classroom.

colloquium in 2011 where affect (motivation, beliefs, anxiety, etc.) in TBLT is a central research focus?
