The use of collaborative classroom interactional tasks is on the rise recently since they incorporate the negotiation of meaning and thus they may be regarded as one of the most efficient ways to ease a learner’s focus on form. This study investigated the immediate and long-term effects of reconstruction editing task on the learning of 20 academic vocabulary items through using five reconstruct...

this study builds on laufer and hulstijn’s (2001) motivational-cognitive construct of task-induced involvement in learning vocabulary and addresses itself to its strong claim that the depth of processing is the overriding factor in learning words. the paper first re-examines the effect of processing load and then of task type on the initial learning and retention of words. to do so, 60 efl lear...

AbstractThe current study examined the modification devices (MDs) used by non-native speakers (NNSs) learning EFL during dyadic task-based interactions. Three meaning-oriented tasks, namely picture-description, spot-the-difference, and opinion-exchange, were used to elicit data from 24(12 male and 12 female, forming 4 male-male, 4 female-female, and 4 male-female dyads) Iranian EFL learners wit...

Multiple-output regression models require estimating multiple parameters, one for each output. Structural regularization is usually employed to improve parameter estimation in such models. In this paper, we present a multiple-output regression model that leverages the covariance structure of the latent model parameters as well as the conditional covariance structure of the observed outputs. Thi...

this study investigated the effectiveness of individual and collaborative outputbasedfocus-on-form instructional tasks on the acquisition of english inversionstructures by efl learners. moreover, it explored the developmental trend oflearners’ inversion acquisition. to this end, 60 homogeneous efl learners wereassigned to individual and collaborative output groups. they were exposed to textsenc...

This study explored the effect of input vs. collaborative output tasks on Iranian EFL learners’ grammatical accuracy and their willingness to communicate (WTC). In so doing, the study utilized 3 input (i.e., textual enhancement, processing instruction, and discourse) and 3 collaborative output (i.e., dictogloss, reconstruction cloze task, and jigsaw) tasks and compared their effects on 5 Englis...
