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...

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...

A sizeable body of research into instructed pragmatics roots from the noticing hypothesis: comparing im- plicit and explicit instruction. It is only recently that other theories, including the output hypothesis, have been researched as possible explanations of interlanguage pragmatic development. Pursuing the same line of research, the present study addressed the impact of collaborative o...

Today, learners’ interaction and collaborative task performance have attracted increasing attention from language teachers and researchers. The present study investigated whether collaborative pre-planning, task complexity manipulation, and language proficiency level play a role in learners’ interactions. To this end, 128 EFL learners from two different language proficiency levels carried out t...

Privacy-preserving techniques for distributed computation have been proposed recently as a promising framework in collaborative inter-domain network monitoring. Several different approaches exist to solve such class of problems, e.g., Homomorphic Encryption (HE) and Secure Multiparty Computation (SMC) based on Shamir’s Secret Sharing algorithm (SSS). Such techniques are complete from a computat...

This study examined the effects of input-oriented and output-oriented tasks with different involvement load indices on Iranian EFL learners' comprehension and production of lexical collocations. To achieve this purpose, a sample of 180 intermediate-level EFL learners (both male and female) participated in the study. The participants were in six experimental groups. Each of the groups was random...

Distance metric learning has been widely investigated in machine learning and information retrieval. In this paper, we study a particular content-based image retrieval application of learning distance metrics from historical relevance feedback log data, which leads to a novel scenario called collaborative image retrieval. The log data provide the side information expressed as relevance judgemen...
