the present study was conducted to evaluate data driven learning (ddl) combined with computer assisted language learning (call) as an approach to improving vocabulary knowledge of iranian postgraduates majoring in teaching english, english literature and translation. the purpose was to help language learners get familiar with ddl as a student-centered method taking advantage of a computer progr...

In this article we consider nonlinear Schrödinger (NLS) equations in R for d = 1, 2, and 3. We consider nonlinearities satisfying a flatness condition at zero and such that solitary waves are stable. Let Rk(t, x) be K solitary wave solutions of the equation with different speeds v1, v2, . . . , vK . Provided that the relative speeds of the solitary waves vk − vk−1 are large enough and that no i...

The latency of the brain response to semantic anomalies (N400 effect) has been found to be longer in a bilingual's second language (L2) than in their first language (L1) and/or to that seen in monolinguals. This has been explained in terms of late exposure to L2, although age of exposure and language proficiency are often highly correlated. We thus examined the relative contributions of these f...

Abstract To probe the limits of attention raising through form-focused instruction, second-language research must adapt to needs a technologically driven learning environment. In this study, we used randomized control design investigate effect captioned media on vocabulary and grammar in L2 Spanish ( n = 369 learners). Through four data-collection sessions, participants were presented with gram...

The present study investigated the effects of selected presentation techniques including the keyword method, the peg word method, the loci method, argument mapping, concept mapping and mind mapping on L2 vocabulary comprehension and production. To this end, a sample of 151 Iranian female students from a public pre-university school in Islam Shahr was selected. They were assigned to six groups. ...

It remains unsettled whether human language relies exclusively on innately privileged brain structure in the left hemisphere or is more flexibly shaped through experiences, which induce neuroplastic changes in potentially relevant neural circuits. Here we show that learning of second language (L2) vocabulary and its cessation can induce bidirectional changes in the mirror-reverse of the traditi...

The present study serves to demonstrate that learning new L2 vocabulary items in association with unique cues can have a rather dramatic effect on the way in which the newly learned items are processed. In the present study, participants learned new L2 vocabulary items in association with either familiar line drawings or uniquely colored pictures. It was found that new L2 words learned in assoc...

this study has examined the effect of semantic mapping on learning vocabulary across genders. the researchers selected 120 intermediate students after the administration of a standard proficiency test. a vocabulary test was also used to measure the students’ vocabulary knowledge. the experimental group received semantic mapping in the pre-reading stage, butthe control group did not receive this...

The  present  study  investigated  the  effects  of  three  methods  of  vocabulary  presentation,  i.e., picture,  song,  and  the  keyword  method  on  Iranian  EFL  learners'  vocabulary  recognition  and production.  The  participants  were  102  Iranian  lower-intermediate  EFL  learners  in  Zaban  Sara English language institute in Kermanshah. To make sure that they had no previous knowl...

  A growing body of research has indicated that students of ESL/EFL are reticent and unwilling to be engaged in oral activities in English lessons. Communicative language ability includes speaking ability, so vocabulary knowledge plays an integral role in speaking a language. However, there have been few studies examining the degree to which vocabulary knowledge affects speaking ability. The pr...
