One benefit of working in groups is that group members can learn from each other how to perform the task, a phenomenon called group-to-individual transfer (G-I transfer). In the context of quantitative judgments, G-I transfer means that group members improve their individual accuracy as a consequence of exchanging task-relevant information. This…

This article reports a classroom-based study of the effects of two types of corrective feedback (CF) on the acquisition of 3rd person "-s." One hundred and nine Chinese university students completed three communicative tasks: One group received implicit CF consisting of a single corrective move (implicit recasts), a second group received…

This study employed a multisite design to investigate the differential impact of deductive and guided inductive instruction for second language (L2) grammar development in ecologically valid classroom contexts. Students (n = 138) from eight intact third-year L2 Spanish classes in three public high schools in the United States received deductive…

Explicit pronunciation instruction enhances production of intelligible, comprehensible, and fluent second language (L2) speech. Additionally, task-based instruction (TBI) enhances the production of segmentals and suprasegmentals, and promotes awareness of L2 forms in pronunciation. Since most previous research on TBI in L2 pronunciation learning…

This study is the first to compare objective and subjective measures of explicit and implicit knowledge under learning from incidental exposure. An experiment was conducted, during which L1 English speakers were trained on a semiartificial language, "Japlish." A measure of explicit knowledge and a recently proposed measure of implicit…

Emphasis manipulation is a way to help learners by directing their attention to particular subcomponents of a learning task. This study investigated the effects of different approaches to emphasis manipulation on knowledge transfer and cognitive load. This was done by examining the impact of three task selection strategies: system-controlled,…

This study was an attempt to investigate the effect of choice theory-based instruction on Iranian EFL learners' vocabulary achievement. To fulfil the purpose of this study, 60 female advanced EFL learners were selected from among a total number of 90 learners through their performance on a piloted sample Cambridge ESOL Certificate of Advanced…

The present study investigates the effect of the first language (L1) on learners by using the negative and the positive evidence in the classrooms while teaching English directional prepositions such as 'to' and 'into'. It is assumed that Arabic has two versions of 'to'. It has the directional interpretation without boundary-crossing which is…

Research has confirmed the benefits of pragmatics instruction for a variety of speech acts, including suggestions and requests. However, less is known about the effectiveness of instruction for disagreements, which are face-threatening acts that establish a point of view counter to the interlocutor. Therefore, the current study explored the effect…

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 study investigated the effect of dynamic Assessment (DA) on the acquisition of L2 grammar by EFL learners. The focus was on teaching Conditional Type II, or Unreal Conditional, which is a difficult structure for language learners to acquire. To this end, two intact classes of intermediate EFL learners, each consisting of 23 male students were…

This study introduces an approach to providing corrective feedback to L2 learners termed analogy-based corrective feedback that is motivated by analogical learning theories and syntactic alignment in dialogue. Learners are presented with a structurally similar synonymous version of their output where the erroneous form is corrected, and they must…

The present study aims to investigate the role of extensive reading in the acquisition of implicit phonological knowledge. Through extensive exposure to print, L2 learners can improve their phonological processing skills, and this could contribute to their word recognition fluency. On the basis of the Oxford Placement Test, 30 9th graders and 30…

It is widely accepted that L2 learners often face communication problems due to lack of competency in the target language and familiarity with its culture of origin. One way to resolve miscommunication problems is to seek clarification of the utterance; this process is called "repair negotiation" (Nakahama et al. 2001). Repair…

This dissertation tests a grammatical structure, differential object marking (DOM), which is particularly difficult for L2 learners to acquire. DOM is a phenomenon in which some direct objects are morphologically marked to distinguish them from subjects (Comrie, 1979). In Spanish, animate and specific direct objects are marked with the preposition…
