Certain weaknesses of Expert System technology became apparent in the early 80's. Among them were the `knowledge acquisition bottleneck' and problems of robustness. Among the proposals in the 1980s to resolve these problems are Case Based Reasoning (CBR) and Task Speci c Architectures (TSA). Case Based Reasoning resolves these problems by representing knowledge in cases cases are generalized wh...

lead (pb2+) is a well known neurotoxin that was frequently found in the environment and chronic exposure to lead has been matter of public health. in the present study the effect of lead on spatial memory in developmentally exposed rats and their dams in morris water maze task were investigated. female rats were divided into three groups and two groups exposed to 250 and 750 part per million (p...

this paper examines the theoretical rationales and practical aspects of task-based language teaching (tblt) with particular reference to research findings in efl/esl contexts. the definitional scope of the term ‘task’, polarizations in terms of task vs. non-task, and its relation to different language teaching approaches have engendered conceptual and methodological ambiguities.  moreover, fact...

conclusions meeting the prerequisites to incorporating tbl in the curriculum of medical universities plays a pivotal role in its success. accordingly, in the assessment of the curriculum of medical universities, these requirements should be fully identified and fulfilled so as to be able to devise appropriate plans for the success of teaching methods. context this review study, performed in 201...

task-based language teaching (tblt) has been considered as an effective language teaching methodology. however, its applicability for lower-proficiency learners in efl contexts has not been adequately justified. moreover, the possible mediating effect of the experiential learning styles on academic listening tblt has not been targeted in the literature, a gap that this study attempts to fill. t...
