OutlineOutline
“Tasks are L2 classroom activities to be completed through the medium of the L2, but with intrinsically motivating/worthwhile goals other than language practice”
(Ros Mitchell, 2000:296).
Task repetitionTask repetition
CAF compete for learners’ attention (Skehan, 2009)
Repetition helps learners to integrate the competing demands of CAF (Bygate, 1999).
When exposed to new versions of the task, learners deal with task variations more effectively (Helgesen, 2003) .
Complexity, Accuracy, and Fluency Complexity, Accuracy, and Fluency (CAF)(CAF)
C = The use of challenging language (Skehan, 2009).
A = The quality of being congruent with norms (Housen & Kuiken, 2009).
F = Ability to speak at a normal rate without hesitation (Nunan, 1999).
Research Questions
1. Does task repetition lead to increased complexity, accuracy and fluency in
performance of the same task?
2. Does any improvement from task repetition transfer to performance in a new task?
The main task phase
What did you do on Sunday from morning to evening?
Tell me everything about your last school trip.
Talk about your favourite movie.
What do you do at juku from start to finish?
What do you see in this picture, and what are they doing?
New-task phase
How do you make a cup of tea/coffee?
What are your best two subjects in school and why do you like them?
Who is your favourite sportsperson, and why do you like him/her?
Tell me what you see in this picture.
COMPLEXITY
Percentage of utterances including verbs =(Number of turns with verbs/total number of turns) X
100.(Yuan and Ellis, 2003)
Percentage of utterances with complete sentences = (Number of turns having complete sentences/the total
number of turns) X 100. (Bygate, 2001; Kawauchi, 2005 in Ellis, 2009)
ACCURACYPercentage of error-free turns =
(Number of error-free turns/the total number of turns) X 100
(Larsen-Freeman, 2006)
FLUENCY
Total number of words.(Larsen-Freeman, 2006)
Total number of pruned words =Total number of words less dysfluent words
(Derwing, Munro, Thomson & Rossiter, 2009).
Ratio of total words to dysfluent words =Total number of words divided by the total
number of dysfluent words(Ellis, 2009).

years ago, no… (laughter) twenty five years ago.

Benefits
Complexity seems to benefit the most. Comparable to Bygate (2001).
Fluency gains were transferred to the new task.Transfer gains lead to acquisition (Ellis, 2009).
Lowered anxiety level, leading to greater WTC in class activities.
Increased self-confidence and greater collaboration.
Perhaps, better L2 perception.

Limitations
Sample size.
Week 1 vs New Task.
Asynchronous nature of the task.
Self-selection (killer).
Future research
Microanalysis of CAF to establish interrelationship.
