This article offers a methodological synthesis spanning 35 years of instructed second language acquisition research on the efficacy of form-focused instruction. Eighty-eight (quasi-) experimental studies were sampled from six academic journals: "Applied Linguistics," "Language Learning," "Language Teaching Research,"…

We evaluated the effects of tact and listener instruction on the emergence of bidirectional intraverbal relations with 6 typically developing Brazilian children, using an adapted alternating treatment design with pretest and posttest probes. In listener instruction, participants selected pictures that corresponded to spoken foreign-language words.…

This study aimed at investigating EFL pre-service teachers' attitudes towards pronunciation and pronunciation teaching. Another purpose was to explore the outcomes of pronunciation instruction of EFL pre-service teachers' phonological development and, based on the findings, to provide suggestions taking learners' pedagogical needs into…

The present article argues for a conceptual distinction between corrective feedback and mediation that emphasizes the status of the latter not as an instructional practice but as a defining feature of human psychology (Vygotsky, 1987) that has direct implications for how instruction might be approached. Specifically, Sociocultural Theory (SCT)…

There is considerable evidence that incidental vocabulary acquisition through reading accounts for a large portion of the growth in word knowledge for both first (L1) and second (L2) language acquirers. In this paper, we evaluate the Markov Estimate of Semantic Association (MESA) technique for detecting small, incremental gains in vocabulary…

Service-learning has increasingly been implemented to enhance teacher education coursework in the field of Teaching English to Speakers of Other Languages (TESOL). Service-learning engages preservice teachers in activities or projects that benefit a particular community of stakeholders with ties to English as an additional language learning while…

This paper aims to analyse the role of time concentration of instructional hours on the acquisition of formulaic sequences in English as a foreign language (EFL). Two programme types that offer the same amount of hours of instruction are considered: intensive (110 hours/1 month) and regular (110 hours/7 months). The EFL learners under study are…

In this paper we evaluate the effectiveness of an adaptive online learning platform, designed to support Chinese students in learning the English language. The adaptive platform is studied in three studies, where the experimental platform is compared to an alternate, non-adaptive platform, with random assignment to conditions (the adaptive…

Jim Greer and his colleagues argued that student modelling is essential to provide adaptive instruction in tutoring systems and showed that effective modelling is possible, despite being enormously challenging. Student modelling plays a prominent role in many intelligent tutoring systems (ITSs) that address problem-solving domains. However,…

This study investigates whether practice with computer-administered feedback in the absence of meaning-focused interaction can help second language learners notice the corrective intent of recasts and develop linguistic accuracy. A group of 218 beginning Anglophone learners of Spanish received 1 of 4 types of automated feedback (no feedback,…

Students living in disadvantaged contexts and whose second language is English (ESL) are at risk of not succeeding in school mathematics. It has been internationally recognised that students' socioeconomic background and their achievements in mathematics is more pronounced for Australian students (Thomson et al. 2011). This gap is even more…

Using extant data, the purpose of this study is to examine methods for determining response to intervention (RTI) in a sample of kindergarten English Learners (ELs). Three commonly used methods for determining RTI--(a) benchmark criteria, (b) slope discrepancy, and (c) dual discrepancy--are investigated. Participants included 117 ELs. Students…

This study examined the effectiveness of explicit instruction on second language (L2) learners' implicit and explicit knowledge of English. Explicit instruction on the generic and non-generic use of English articles was delivered by CALL activities. Four tasks assessed acquisition: elicited imitation, oral production, grammaticality judgement, and…

This paper explores the outcomes of the first year of the implementation of a mathematics program ("Representations, oral language and engagement in Mathematics": RoleM) which is framed upon research relating to effectively supporting young Indigenous students' learning. The sample comprised 230 Indigenous students (average age 5.76…

Vocabulary knowledge is of fundamental importance to reading comprehension, and many students lack the vocabulary knowledge necessary to facilitate learning to read. A study was conducted to determine the effects of an individualized, online vocabulary program on picture vocabulary test scores. Elementary summer school students (N = 43), entering…
