Task-based research has shown the benefits of using tasks in various instructional contexts across different age groups. Although task-based language teaching promotes language learning through authentic real-world tasks, previous research has mainly used controlled pedagogic tasks. The current exploratory, intact-classroom, multi-case study…

The present meta-analysis aimed to summarize the extent to which second language vocabulary is learned from the most frequently researched word-focused activities: flashcards, word lists, writing, and fill-in-the-blanks. One hundred effect sizes from 22 studies were included in meta-regression analyses and administered separately for the…

The current 2-part study investigated the relative contributions of English language training (ELT) and computerized Cogmed working memory training (WMT) to improvements in English-as-a-foreign language (EFL) proficiency and working memory capacity. In Study 1, Japanese undergraduate EFL learners were randomly allocated to 1 of 3 experimental…

Despite years of research on vocabulary learning and teaching, relatively little is known about strategies for effective mastery of vocabulary in less commonly taught languages. The current study focuses on English native speakers studying Modern Standard Arabic to identify effective ways to present and learn new vocabulary using tasks varying in…

This study examined the effectiveness of Zipfian frequency at facilitating the acquisition of English prenominal past participles. Chinese middle school students (N = 103) were randomly assigned to a sequenced Zipfian frequency (SZF) group, a random Zipfian frequency (RZF) group, a balanced frequency (BF) group, and a control group. A mixed…

Using structural equation modeling analysis, this study examined the contribution of vocabulary and grammatical knowledge to second language reading comprehension among 190 advanced Chinese English as a foreign language learners. Vocabulary knowledge was measured in both breadth (Vocabulary Levels Test) and depth (Word Associates Test);…

This study examined the abilities of young English as a foreign language (EFL) learners to identify quickly new words from a nonostensive, indirect teaching context (known as fast- mapping) and their ability to commit the words to memory. Seventy-five fourth-grade EFL learners heard novel words embedded in sentences. They were then tested for…

Over the past 2 decades, research has demonstrated that learner collaboration facilitates second language (L2) acquisition (Lapkin, Swain, & Smith, 2002; McDonough, 2004; Storch, 1998, 2004; Swain & Lapkin, 1998). Adopting a sociocultural perspective (e.g., Swain & Lapkin, 1998), the current study compared the effectiveness of collaborative and…

This study investigated semantic transfer in second language (L2) learning and provided a replication of the author's study (Jiang, 2002) in a different English as a Second Language (ESL) population. Korean ESL speakers were asked to perform a semantic judgment task in which they decided whether or not 2 English words were related in meaning. Two…
