the favorable gains gleaned from the provision of pre-task planning time (ptp) have struck a chord with sla researchers as they try to manipulate task features to promote language production and development. in a similar vein, the present study is a two-fold attempt to first compare the effect of the length of pre-task planning time on discourse-analytic measures in narrative written production...

This paper presents an application of Hierarchical Transition Network (HTN) planning to a squad-based military simulation. The hierarchical planner produces collaborative plans for the whole squad in real time, generating the type of highly coordinated behaviours typical for armed combat situations involving trained professionals. Here, we detail the extensions to HTN planning necessary to prov...

This study aimed at examining the main and interaction effects of increased intentional reasoning demands, planning time, and also language learning aptitude on syntactic complexity, accuracy, lexical complexity, and fluency (CALF) of 226 EFL learners’ performance on letter writing tasks. The participants were first randomly assigned to three experimental groups to be given a task with differin...

In the realm of second language acquisition (SLA), task-based language teaching (TBLT) and input enhancement (IE) have been the focus of a great number of studies. However, the idea of investigating the effects of focus on form instruction through input-enhanced tasks along with pre-task planning time as one of the features of task-based language teaching has been rarely explored in the field o...

Building on Robinson’s (2001, 2003) Cognition Hypothesis, Skehan’s (1998) Limited Attentional Capacity Model, and Kellog’s (1986) model of writing, this study examined the effect of task planning on the fluency, accuracy, and complexity of 60 Iranian EFL learners’ argumentative and narrative writings under different planning conditions. A quasi-experimental design with three levels of planning ...

The favorable gains gleaned from the provision of pre-task planning time (PTP) have struck a chord with SLA researchers as they try to manipulate task features to promote language production and development. In a similar vein, the present study is a two-fold attempt to first compare the effect of the length of pre-task planning time on discourse-analytic measures in narrative written production...

research on pre-task planning has revealed that planned conditions have produced more fluent and complex language than unplanned conditions. to date, most of these studies have investigated the effects of individual planning on language production while collaborative planning has received scant attention. to determine the effects of pre-task planning on second language written production, the p...
