In this article, we present an analysis of the complexity of grammatical constraints and their impact on early language acquisition of inflectional morphemes in Malayalam. We use the natural speech production data of two monolingual children acquiring Malayalam between the ages 1;9-2;10 and 2;3-3;0 and three bilingual children acquiring…

This longitudinal case study investigated the developmental trajectories of two participants enrolled in an ITA oral communication course at Purdue University. The course provides language support to the ITA population who play a crucial role in higher education programs in the U.S. (Gorsuch, 2016). Over four months (i.e., one semester), I…

In this research study, unlike previous studies that have examined the advantages of peer review for low proficiency students, uses a longitudinal action mixed methods design is used to explore the impact of peer review on the academic writing of students with low English proficiency. The format was a longitudinal action study, which analyzed the…

The current study responds to the call for increased dialogue among different areas of additional language research. Specifically, we bring together learner corpus research and variationist approaches to second language acquisition to advance learner corpus research in two ways: (a) by modeling interlanguage development and variability and (b) by…

This article reports the results of the first longitudinal study that systematically investigates the acquisition of verb agreement by hearing learners of a sign language. During a 2-year period, 14 novel learners of Sign Language of the Netherlands (NGT) with a spoken language background performed an elicitation task 15 times. Seven deaf native…

A body of previous work in second- and foreign language pronunciation instruction (e.g., Lord, 2005; Miller, 2012) has shown that explicit phonetic and pronunciation instruction is beneficial. However, Olson (2014) noted that just a few minutes per week of instruction are devoted to pronunciation in most classrooms. What is the effect of such…

Developing literacy in two languages can be challenging for young bilingual children. This longitudinal study investigates the effects of bilingualism in the spelling strategies of English-Portuguese speaking children. A total of 88 six- to-seven-year-old bilinguals and monolinguals were followed during one academic year and data gathered on a…

This paper analyzes the spoken corpus of thirty Iranian learners of French at four levels (A1, A2, B1 and B2). The data were collected in a pseudo-longitudinal manner in semi-directed interviews with half closed and open questions to analyze the learners' syntactic errors (omission, addition, substitution and displacement). The most frequent…

The present paper compares the vocabulary development of a group of CLIL and of traditional EFL learners along three years. The observation that a CLIL approach might provide with larger benefits in the long-run vocabulary is the starting point of this study. We had learners in the two groups complete a letter-writing task. These writings were…

Han's (2009, 2013) selective fossilization hypothesis (SFH) claims that L1 markedness and L2 input robustness determine the fossilizability (and learnability) of an L2 feature. To test the validity of the model, a pseudo-longitudinal study was designed in which the errors in the argumentative essays of 52 Iranian EFL learners were identified and…

The article discusses the potential of combining learner corpus research with experimental studies in order to fine-tune the understanding of learner language development. It illustrates the complementarity of the two methodological approaches with data from an ongoing study of the acquisition of the English tense and aspect system by French…

Within the Australian education system, Aboriginal students' use of non-standard English features is often viewed simplistically as evidence of non-attainment of literacy and oral-English milestones. One reason for this is the widespread use of assessment tools which fail to differentiate between native-English speakers and students who are…

Methods for analysing interlanguage have long aimed to capture learner language in its own right. By surveying the cognitive methods of Error Analysis, Obligatory Occasion Analysis and Frequency Analysis, this paper traces reformulations to attain this goal. The paper then focuses on Emergence Analysis, which fine-tunes learner language analysis…

Within a Dynamic System Theory (DST) approach, it is assumed that language is in a constant flux, but that differences in the degree of variability can give insight into the developmental process. This longitudinal case study focuses on intra-individual variability in accuracy rates and complexity measures in Finnish learner language. The study…

Detailed research concerning the issue fluency, specifically relating to pauses, mean length runs, and fluency rates in Japanese EFL learners, is limited. Furthermore, the issue of tracking fluency gains has often been ignored, misunderstood or minimized in EFL educational research. The present study, which is based on six monologues conducted…
