This study investigates the differential effects of a task-based inside-school intervention and an outside-school project intervention on the development of speaking skills of 56 beginner second language (L2)-learners. The study extends previous research by looking at development across multiple occasions instead of two (i.e., a pretest and…

Open access academic lectures are potential sources for incidental vocabulary learning. These lectures are available in various formats (transcripts, audios, videos, and video with captions), but no studies have compared the learning of vocabulary in these lectures through different input modes. This study adopted a pretest-posttest design to…

Conversation-for-learning (Kasper and Kim 2015) is a pedagogical arrangement set up with a view to maximizing the potential benefit of interaction for language learning. As participants for conversation-for-learning are recruited for their relative expertise in the target languages, the talk is often characterized by asymmetries in knowledge and…

Learners' self-initiated language learning with mobile technology occurring outside the classroom is often contextualized, heterogeneous, and idiosyncratic. In this study, we propose a time-series clustering methodology for researching informal mobile language learners' learning and development of another language, with a view to unravelling the…

This investigation responds to the need for longitudinal data-driven research on additional-language (AL) acquisition by examining grammatical-gender marking among AL learners of French during a 21-month period, which included an academic year abroad (LANGSNAP corpus). The analysis of oral production consists of a generalized linear mixed model…

This longitudinal study examined growth patterns of written syntactic complexity of Turkish learners of English. Using a nonexperimental corpus of 852 writing samples by 284 English as a foreign language (EFL) learners over three semesters, the study addressed the following questions: which indices of syntactic complexity characterize the writing…

The role of awareness has been under investigation in second language (L2) acquisition research for many years. Williams' study (2005) has attracted particular interest and has been actively reexamined from a variety of perspectives, and the replications and extensions of the research currently form a research horizon on the intersection of…

Do adults learn the same syntactic second language (L2) form explicitly and implicitly simultaneously during meaning-based exposure, and does the type of learning (explicit and/or implicit) affect subsequent performance. In this study, 81 anglophones completed comprehension tasks providing incidental exposure to a semi-artificial language (English…

Epistemics in interaction refers to how participants display, manage, and orient to their own and others' states of knowledge. This article applies recent conversation analytical work on epistemics to classrooms where language and content instruction are combined. It focuses on Epistemic Search Sequences (ESSs) through which students in peer…

Vygotskian sociocultural theory of mind holds that language mediates thought. According to the theory, speech does not merely put completed thought into words; rather, it is a tool to refine thought as it evolves in real time. This study investigated from a sociocultural theory of mind perspective how nine beginning learners of Latin used private…

This paper responds to calls for studies that investigate multiple types of word knowledge and the processes of word learning. Focusing on a single word, this three-month diary study describes the micro-development of an adult male's Japanese L2 lexical knowledge. In contrast to most L2 vocabulary acquisition studies, this study posits a dynamic…

This paper draws on the Vygotskian methodological construct of microgenesis to study collaborative activity in an intermediate Spanish as a foreign language classroom. In this study, the construct of "microgenesis" is drawn upon to refer to both, the methodological "tool" to investigate language learning instances as observed in short periods of…

One of the great puzzles of language acquisition has been described as poverty of the stimulus: how are complex aspects of language acquired when they appear to be rare or even non-occurring in the input that a learner receives and comprehends? This article presents an emergentist solution to one aspect of this puzzle (involving relative clauses)…

Analyzed sound systems of six phonologically disordered children and assessed relative phonological knowledge of target sounds. After-treatment results indicated that error sounds of which the children had the most knowledge were easiest to learn. Treatment beginning with the most difficult sounds resulted in more widespread changes in the…

Describes the study of learning strategies employed by successful (defined in terms of oral communicative abilities) Chinese learners of English. These strategies are compared to those of less successful learners and those of other population types from other studies. The test of oral communicative abilities is described. A strategies…
