The problem of decentralized multiple Point of Interests (PoIs) detection and associated task completion in an unknown environment with multiple resource-constrained and self-interested Unmanned Aerial Vehicles (UAVs) is studied. The UAVs form several coalitions to efficiently complete the compound tasks which are impossible to be performed individually. The objectives of such coalition formati...

Despite the recent surge in research on unsupervised category learning, the majority of studies have focused on unconstrained tasks in which no instructions are provided about the underlying category structure. Relatively little research has focused on constrained tasks in which the goal is to learn predefined stimulus clusters in the absence of feedback. The few studies that have addressed thi...

Pair and small group work is infrequently welcomed in English as a Foreign Language (EFL) classes under the assumption that students tend to use their first language (L1), which is considered detrimental to learning the new language. From sociocultural perspective, however, students’ first language is claimed to play the role of an important psychological tool and can facilitate the learning pr...

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...

Developing reading comprehension ability is an important aspect in acquisition of a language. The  present  study  focused  on  improving  reading  comprehension  ability  through  Task-based Instruction  (TBI).  TBI  is  a  methodology  that  develops  from  a  focus  on  classroom  tasks.  The participants of the study were 135 Iranian female students at different levels selected from high sc...
