This study investigated the effect of sequencing tasks from simple to complex along +/- reasoning demands on fluency in writing task performance of English as Foreign Language (EFL) learners. The participants of this study included 90 intermediate EFL learners from three intact class divisions at the Islamic Azad Uni- versity, Shahr-e-Qods Branch. They were distributed in three groups: Experime...

This study was an attempt to investigate the comparative impact of two types of teaching approaches, namely content-based (CBI) and task-based (TBLT) instruction on the reading comprehension of Iranian EFL learners. For this purpose, sixty intermediate students from a pool of eighty five students studying at a private language school were chosen using a piloted PET. The students were then rando...

We consider the problem of relating an agent’s internal state (its beliefs and goals) and its social state (its commitments to and from other agents) as a way to develop a comprehensive account of decision making by agents in a multiagent system. We model this problem in terms of hierarchical task networks (HTNs) and show how HTN planning provides a natural representation and reasoning framewor...

An important focus of recent CBR research is on how to develop strategies for achieving compact, competent case-bases, as a way to improve the performance of CBR systems. However, compactness and competence are not always good predictors of performance, especially when problem distributions are non-uniform. Consequently, this paper argues for developing methods that tie case-base maintenance mo...

Presented paper describes the development of comprehensive approach for knowledge processing within e-Sceince tasks. Considering the task solving within a simulation-driven approach a set of knowledge-based procedures for task definition and composite application processing can be identified. This procedures could be supported by the use of domain-specific knowledge being formalized and used fo...

Based on Robinson’s Cognition Hypothesis, this study explored the effects of task complexity on the lexical complexity of Iranian EFL students’ argumentative writing.This study was designed to explore the manipulation of cognitive task complexity along +/-single task dimension (a resource dispersing dimension in Robinson’s triadic framework) on Iranian EFL learners’ production in term of lexica...

Growth in the mobile internet services industry has seen a marked increase in the number of mobile internet services provided, and this has made proper structuring and organization of the services difficult. Present methods of service provision have proven insufficient to guide users efficiently to the services they need. To solve this problem, a task-oriented menu, which enables users to searc...
