in this paper an efficient three- stage algorithm is developed for software production cost and time estimation. first stage includes a hybrid model composed of cocomo and function points methods to increase estimation accuracy. second stage encompasses paired comparisons matrix of analytical hierarchy process to determine amount of any resources consumed in each step of software production by ...

background: cerebrovascular disease leading to stroke is the most common cause of aphasia. speakers with agrammatic non-fluent aphasia have difficulties in production of movement-derived sentences such as passive sentences, topicalized constituents, and wh-questions. to assess the production of complex sentences, some passive, topicalized and focused sentences were designed for patients with no...

The main purpose of the study reported in this paper was to examine the interrelationships between L2 risk-taking, English learning motivation, L2 speaking anxiety, linguistic confidence, and low-proficiency English as a foreign language (EFL) learners’ speaking complexity, accuracy, and fluency (CAF). A secondary purpose was to test whether task repetition can influence the level of the mentio...

The main purpose of the present quasi-experimental study was to investigate the effects of linear process versus genre-based approach on EFL learners’ written production. To this end, 40 learners of English at intermediate level were randomly selected as the participants of the study and assigned into two groups of experimental (process and genre) which received different types of instruction f...

The main purpose of the present quasi-experimental study was twofold; its first purpose was to investigate the effects of using of two approaches namely; genre and process on EFL learners’ accuracy, fluency, and complexity in written task production. Secondly, it attempted to investigate the effects of mentioned approaches on EFL learners’ attitude toward writing skill. to this end, 60 learners...

The  present  meta-analysis  was  conducted  to  provide  a  quantitative  measure  of  the overall effects of task complexity on Chinese EFL learners’ language  production.  Based  on  the strict inclusion criteria, 12 primary  studies  were synthesized according to key  features.  Eleven of them  were  meta-analyzed  to  investigate  effects  of  raising  the  resource-directing  task  comple...

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...
