When expiratory flow is maximal during tidal breathing and cannot be increased unless operative lung volumes move towards total lung capacity, tidal expiratory flow limitation (EFL) is said to occur. EFL represents a severe mechanical constraint caused by different mechanisms and observed in different conditions, but it is more relevant in terms of prevalence and negative consequences in obstru...

This study aimed at investigating the effect of instructional YouTube videos on Iranian male and female EFL learners' listening comprehension. It was conducted with 60 male and female intermediate male and female EFL learners. The Oxford Quick Placement Test (OQPT) was used to measure the participants’ language proficiency to make sure about homogeneity of the participants. The participants wer...

The present study examined the acquisition of anaphora in English by Iranian EFL learners as well as Persian speaking children. To do so, the study was conducted in three phases. In the first phase, 40 intermediate female and male EFL learners were selected from Puyan Institute in Takestan, Iran. Then, an off-line based Grammatical Judgment Task was administered. In the second phase, 40 female ...

This  case  study  analyzes  how  a  Taiwanese  EFL  teacher  participating  in  a  U.S.  based MATESOL program made sense of systemic functional linguistics (SFL) and genre based pedagogy  in  designing  and  reflecting  on  literacy  instruction  for  EFL  learners  in  Taiwan. Using  longitudinal  ethnographic  methods,  the  findings  indicate  that  this  teacher’s conceptualization  of  g...

Tidal expiratory flow limitation (EFL) may promote dynamic hyperinflation and contribute to chronic dyspnoea. The purpose of this study was to assess the contribution of EFL to chronic dyspnoea in adults with cystic fibrosis (CF). The presence of EFL was determined in 102 adults with stable CF (forced expiratory volume in one second (FEV1) 17.3-91.5% predicted) and 20 age-matched control subjec...

Student ratings of instruction can be a valuable indicator of teaching because the quality measurement of instruction identifies areas where improvement is needed. Student ratings of instruction are expected to evaluate and enhance the teaching strategies. Evaluation of teaching effectiveness has been officially implemented in Taiwanese higher education since 2005. Therefore, this research inve...

Various vocabulary learning systems have been developed to assist students of English as a Foreign Language (EFL) in acquiring the knowledge of vocabulary. By using the electronic dictionary, people only acquire vocabularies on a superficial. Most corpus-based system focuses on lexical explanation, such as giving synonyms and antonyms. Only a few studies have attempted to use lexical structures...

Regional expiratory flow limitation (EFL) may occur during tidal breathing without being detected by measurements of flow at the mouth. We tested this hypothesis by using Technegas to reveal sites of EFL. A first study (study 1) was undertaken to determine whether deposition of Technegas during tidal breathing reveals the occurrence of regional EFL in induced bronchoconstriction. Time-activity ...

The analysis of current EFL (English as a Foreign Language) education and literature indicates that most EFL practices can be characterised as traditional language learning settings in which teachers direct the learning process, and students are then assumed as passive receptors of knowledge. Furthermore, EFL learning has also been criticised as an in-class-only learning practice due to the rar...

This study aimed at investigating the effect of using wikis to develop prospective English as a Foreign Language (EFL) teachers' writing performance. The participants were fourth year prospective EFL teachers at Suez Faculty of Education in Egypt. Thirty prospective EFL teachers participated in each of the experimental and control groups. Both groups were pre-tested by using the Writing Perform...
