Research shows many problems and ambiguities of second language acquisition (SLA), which have made learners and readers worldwide unsatisfied. Therefore, this study attempts to highlight theories and research that have comprehensive explanations of the problems and ambiguities of second language acquisition, which learners of English as a Foreign…

This study investigates the acoustic realizations of English phonemic contrasts by Korean EFL learners, comparing their productions with those of native English speakers. Focusing on the segmentally correct production, the research aims to determine if Korean learners' acoustic properties align with those of native speakers, influenced by second…

This paper provides an experimental study of interlanguage phonological characteristics of Chinese students learning Thai as a foreign language and the accentedness perceived by native Thai speakers. Both production and perception experiments were designed to see how Chinese students acoustically produced Thai final nasal consonants and how Thai…

Though dynamic assessment (DA) has gained strong theoretical and empirical support over the last decades, second language (L2) practitioners have blamed it for its applicability in large classes. To ameliorate this limitation, peer-dynamic assessment (peer-DA), rooted in the conceptualization of zone of proximal development (ZPD), can be…

This article reports on a study exploring the differential effects of immediate and delayed corrective feedback (CF) on the acquisition of the English past tense. One hundred and forty-five seventh-grade EFL learners were assigned to four groups: Immediate CF, Delayed CF, Task Only, and Control. Each experimental group performed six focused…

This study explored the effects of concurrent group dynamic assessment (G-DA) and cumulative G-DA on Iranian pre-intermediate English as a foreign language (EFL) learners' interlanguage pragmatic comprehension (ILPC). To this end, a total of 97 pre-intermediate learners took the key English test (KET) test and 45 learners whose scores fell between…

Research into instructed pragmatics mainly comparing implicit and explicit instruction has gained salience in language teaching research in the last two decades. The present study was designed to investigate the effect of cognitive and interpersonal task-based instruction on EFL Learners' production of two speech acts of apology and request. To…

This dissertation examines the development of the internal structure of the Korean syllable by adult Korean learners whose native language is English. Prior research has identified the prominence of the body constituent in Korean and the rime constituent in English. The current study focuses on the acquisition of the body unit by English speakers…

This study investigates the effects of input-based and output-based instructions on the acquisition of second language (L2) request modifiers. Four intact classes were randomly assigned to textual enhancement (TE), input flooding (IF), output-based instruction (OI), and control (CO) groups. The TE group watched some captioned videos on requests…

This study aims to advance the understanding of sociolinguistic competence among near-native speakers and to further knowledge about the acquisition of variable structures. We conduct a quantitative analysis of variable future-time expression in informal conversations between near-native and native speakers of French. In addition to examining…

In this article we look at some of the structural properties of second language (L2) Japanese WH questions. In Japanese the WH words are licensed to remain "in situ" by the prosodic contiguity properties of the phrases which have no prosodic boundaries between the WH word and the question particle. In a rehearsed-reading, sentence…

Learning to use prepositions in English as a second language (L2) has been widely acknowledged to pose significant difficulties to learners, especially within metaphorical contexts. Difficulties relate to the complex distributional patterns of prepositions in discourse, namely, the variety of collocations requiring their use, as well as…

There have been a number of studies on the use of complaints as a speech act. The majority of these studies have included analysis of how different first language speakers make complaints while only a limited number of studies have examined the effects of instruction on the development of complaints as a speech act. Those that have examined this…

The second language (L2) acquisition of tense, aspect, and mood/modality (TAM) has been widely explored as it holds the promise of a better understanding of the L2 learners' linguistic competences, particularly semantically and morpho-syntactically. This study focuses on the acquisition of the subjunctive mood by L1 English learners of L2 French…

This study investigated the processing of English articles by second language (L2) speakers whose first language (L1) is Korean. Previous studies in L2 English article use had some issues unresolved such as using offline tasks, conflating definiteness with real-world knowledge, and operationalizing definiteness and relevant constructs in ways that…
