This article reports a quasi-experimental study which compared the effectiveness for multiword item learning of three listening-based activities: dictation, dictogloss, and answering text comprehension questions. In a dictation, students write down segments of text immediately after listening to them, whereas in dictogloss students try to…

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,"…

The present study employed a mixed methods quasi-experimental design to investigate the effectiveness of applying motivational strategies and mental imagery (i.e. visionary techniques) to facilitate second language (L2) vocabulary learning. Four treatment sessions were integrated into a six-week language course offered to 150 intermediate students…

This study compared the effectiveness of deductive instruction and guided inductive instruction for developing semantic radical knowledge of Chinese characters. The evaluation was conducted through a quasi-experimental 3-week intervention involving 46 intermediate learners of Chinese as a foreign language (CFL). The results indicated that guided…

Prior research showed that interleaved practice (studying multiple skills at once) is more effective than blocked practice (studying only one skill at a time). This study aims to replicate the benefits of interleaved practice on the proceduralization of second language (L2) syntax and further examines the role of working memory (WM) in different…

This study examined the optimal learning schedule for second language vocabulary within an authentic classroom setting in Hong Kong. Following a pretest, treatment, delayed posttest design, fifty-two primary school students (Cantonese first language) studied 20 English adjectives over two learning episodes under spaced-short (1-day interval) or…

This study examined the effectiveness of explicit instruction and feedback, focusing on degrees of prior knowledge of the personal "a" in intermediate level second language (L2) Spanish. On the pretest, participants (n = 58) completed grammaticality judgment and picture description tasks, which found that learners had different degrees…

This study investigated the effects of three instructional modes: picture-book reading-only (PRO), picture-book reading plus vocabulary instruction (PRVI), and picture-book reading plus reading-based collaborative output activity (PRCOA) on young adult EFL (English as a foreign language) learners' vocabulary acquisition and retention. Eighty…

The role of interactional feedback has long been of interest to both second language acquisition researchers and teachers and has continued to be the object of intensive empirical and theoretical inquiry. In this article, I provide a synthesis and analysis of recent research and developments in this area and their contributions to second language…

Explicit phonetics instruction can help second language (L2) learners to moderately improve their pronunciation, but less is known about how the instruction affects learners' perception, even though there is evidence that perception and pronunciation are related. This study provided phonetics instruction to students (n = 46) studying Spanish as a…

In a recent article, Boers, Demecheleer, Coxhead, and Webb (2014) deplored the lack of effectiveness for the learning of verb-noun collocations of a number of exercise formats which they sampled from EFL textbooks and put to the test in a series of quasi-experimental trials. The authors called for further investigations into possible improvements…

The current study examined in depth the effects of suprasegmental-based instruction on the global (comprehensibility) and suprasegmental (word stress, rhythm, and intonation) development of Japanese learners of English as a foreign language (EFL). Students in the experimental group (n = 10) received a total of three hours of instruction over six…

Although repeated reading--a pedagogical practice often involving phonological support in which learners revisit novel forms in context--has been extensively studied in terms of reading fluency and comprehension, little research has explored whether it promotes language acquisition. The current study, an attempt to fill this gap, found that…

Writing for academic purposes in a second/foreign language is a major challenge faced by many students at both secondary and tertiary levels. This suggests that displaying content knowledge and understanding of a subject through a second language is a very complex process. This article discusses the findings of a longitudinal intervention study…

The purpose of this exploratory longitudinal study was to evaluate the efficacy of two new forms of recasts (i.e., elaborated and paraphrased recasts), each of which was designed to be more in accordance with contested views of input processing. The effectiveness of the two new forms of recasts was compared to that of conventional standard…
