Process options differ from task performance options in that they concern the way in which the discourse arising from the task is enacted rather than pedagogical decisions about the way the task is to be handled. Whereas performance options can be selected in advance of the actual performance of the task, process options must be taken in flight while the task is being performed.
The teacher’s on-line decision about how to conduct the discourse of a task reflect his/her
‘theory-in-use’(Schön 1983)and ‘practical knowledge’(Eraut 1994). On the learners’part, they reflect the language learning beliefs(Horwitz 1987)they bring to the classroom and, more particularly, to a specific task. How teachers and learners conduct a task will be influenced, to a large extent, by their prior experiences of teaching and learning and their personal definitions of the particular teaching-learning situation.
A common assumption of task-based teaching is that the texts, the discursive practices and the social practices of the classroom(Breen 1998)that are constructed by and through a task resemble those found in non-pedagogic discourse. To achieve this, however, is no mean feat, especially if the teacher is directly involved in the performance of the task. As Breen points out the ‘texts’of lessons(i. e. the actual language produced by the participants)are typically teacher-centred with learners ‘not actually required to do much overt or explicit discursive work’ (p. 123), while the ‘discursive practices’(i. e. the means by which the text are produced) ‘construct learners as primarily responsive and seemingly fairly passive participants in the discourse’(p. 124)and the ‘social practices’(i. e. the organisational and institutional circumstances that shape the texts and discursive practices)are directed at the avoidance of ‘social trouble’.Task-based teaching, however, seeks the converse- texts that are learner- centred, discursive practices that encourage the learner to actively engage in shaping and controlling the discourse, and social practices that are centred on allowing and resolving social trouble. This poses a problem, which teachers need to address.
