We derive a class of extended one-step methods of order m for solving delay-differential equations. This class includes methods of fourth and fifth order of accuracy. Also, the class of these methods depends on two free parameters. A convergence theorem and convergence factor of these methods are given. In addition, we investigate the stability properties of these methods. The results of the ar...

Speaking and writing are the productive skills of language and share similar components. In other words, writing and speaking are clearly related activities, but the modes of production are different. In addition, among a number of personality variables in predicting English language proficiency, extraversion/introversion has been extensively studied. This quasi-experimental study aims at explo...

Speaking as an initial goal in language teaching and learning has relationships with many variables including listening, reading, writing, knowledge of vocabulary as well as grammar. The present study mainly aims at examining the relationship between translations and speaking fluency. For this purpose and following an experimental design, three groups of Iranian advanced EFL learners were...

Over the last few years, role of computers has become a controversial issue in language learning. This study was designed to examine the impact of computer anxiety and computer self-efficacy on the speaking section of the TOEFL iBT test taken by Intermediate EFL learners. The researchers intended to find out, which var- iable i.e. computer anxiety and/or self-efficacy would result in better per...

This study investigated the effect of role play on improving speaking ability of Iranian pre-intermediate ESP learners. To this aim, the researchers examined the students’ speaking ability in two groups: the experimental and the control groups.24 males and femaleESPlearners at pre-intermediate level were selected by taking a pre-test. Then the participants of the current study were randomlydivi...
