This study investigated the extent to which individual differences in working memory (WM) mediate the effects of captions with or without textual enhancement on attentional allocation and L2 grammatical development, and whether L2 development is influenced by WM memory in the absence of captions. We employed a pretest-posttest-delayed posttest…

The benefit of Content and Language Integrated Learning (CLIL) for second language (L2) development has been addressed by second language acquisition theory and investigated by empirical studies. However, previous studies have not demonstrated the effectiveness of CLIL precisely as most of their study participants took CLIL and non-CLIL courses…

This study assessed the extent to which captions, textually unenhanced and enhanced, can draw learners' attention to and promote the acquisition of a second language (L2) grammatical construction. A pretest-posttest-delayed posttest experimental design was employed. Seventy-two Korean learners of English were randomly assigned to an enhanced…

This experimental study examines the role of oral and written repetition strategies in consolidating new vocabulary in the classroom context. The participants in this study were divided into three treatment groups: oral, written and oral+written. A pretest and three delayed post-tests given at one day, one week and six weeks intervals were…

Some mathematics concepts, especially geometry, have not been understood well by students. The current curriculum in Indonesia strongly recommends the use of manipulatives in mathematics learning. However, the presence of manipulatives only cannot guarantee the students could construct their knowledge of concepts. This research aims to find out…

This study investigated the effects of extensive versus intensive recasts. The focus was on the effect of feedback on learning English articles, which, as nonsalient target structures, have been shown to be difficult for many second language learners. Intensive recasts were operationalized as recasts provided on article errors only, while…

This study launched an investigation into the extent to which textual enhancement in captions can promote learner attention to and subsequent development in second language (L2) grammar. Using eye-tracking, it also intended to extend research on the relationship between attention and L2 learning. A pretest-posttest experimental design was…

Despite a growing amount of research on collaborative dialogue during task performance, little attention has been given to the occurrence of collaborative dialogue across task modality and its impact on language development. To expand our current understanding of task modality effects on learning opportunities, we examined the process of engaging…

This paper studies the pragmatic competence of U.S. heritage speakers of Spanish in an attempt to determine (a) the degree of pragmatic transfer from English to Spanish experienced by heritage speakers when producing different types of requests in Spanish; and (b) how to best teach pragmatics to students of Spanish as a Heritage Language (SHL).…

Given the growing importance of English as a lingua franca, this study examines which context (classroom instruction in the students' home country vs. studying abroad in an English-speaking country) better facilitates the acquisition of English by learners of different ages: children, adolescents and adults. Participants (N = 197) completed…

Among the academic challenges faced by students from low-socioeconomic status (SES) homes is the loss of academic skills during the summer months. A total of 22 elementary students from low-SES homes participated in a summer program designed to improve oral and written narrative skills. We gathered oral and written narrative samples at the…

A quasi-experimental study was conducted to examine the effectiveness of providing written corrective feedback (WCF) to Arab speakers of English on ten uses of English prepositions. Arab speakers commonly find it difficult to correctly use English prepositions, mainly due to the differences between the two languages (e.g. Ortega, 2009). Examples…

This paper reports on task interaction, task success and word learning among second language (L2) learners of different levels of word recognition from speech (WRS) proficiency who used a CALL application previously shown to be effective in the development of L2 WRS. Participants (N = 65) were categorised into three levels of L2 WRS proficiency…

Meta-analytic research suggests an edge of explicit over implicit instruction for the development of complex L2 grammatical structures, but the jury is still out as to which type of explicit instruction--"deductive" or "inductive," where rules are respectively provided or elicited--proves more effective. Avoiding this…

One of the thorniest aspects of teaching languages is developing students' vocabulary, yet it is impossible to be "an accurate and highly communicative language user with a very small vocabulary" (Milton, 2009, p. 3). Nation (2006) indicates that more vocabulary than previously thought is required to function well both at spoken and…
