While a surge of research has investigated the use of reformulations and models as positive evidence feedback (PEF) in second language (L2) writing, so far no research synthesis seeking to review the status quo of this particular topic has been published. To fill the gap, the present study synthesized 23 studies on reformulations and models as PEF…

Self-concept and self-efficacy have been acknowledged as critical predictors of foreign language (L2) learning. However, these two constructs are so closely intertwined that how they function together during L2 learning remains to be determined. The current project aimed to reveal two uncertainties: the bidirectional relationship between L2…

The present study examined the cross-modal cueing effect of musical rhythmic beats on non-native speech rhythm production. Two groups of Chinese learners of French were cued respectively with rhythmic beats that either matched (matching group) or mismatched (mismatching group) the rhythm patterns of the target French sentences. The participants…

Adults learning a new language tend to judge unconventional utterances more leniently than fluent speakers do; ratings on acceptable utterances, however, tend to align more closely with fluent speakers. This asymmetry raises a question as to whether unconventional utterances can be statistically preempted by conventional utterances for adult…

Through signs and symbols, language serves as a means of expressing ideas and sentiments. These signs and symbols are used to encode and decode the information. The world has many different languages in use. As their first language, a baby learns their mother tongue. From birth, he or she is exposed to this language. Any additional language that…

Metacognitive awareness is essential in regulating second language (L2) listening and has been predominantly assessed by a multidimensional instrument named the Metacognitive Awareness Listening Questionnaire (MALQ). Since previous studies have yielded inconclusive evidence concerning the generalization of MALQ, it is important to examine the…

How can syntactic and learnability analyses inform each other, and thus deepen our understanding of syntax and its acquisition? This dissertation illuminates this question through three case studies in Korean syntax. I examine cases in which two structures that display distinct syntactic properties share extremely similar surface forms, thus…

Research has demonstrated that features of lexical and lexicogrammatical use are important predictors of productive second language (L2) proficiency (e.g. Kyle et al. 2018). While some features of lexical use have been studied with L2s other than English (e.g. Tracy-Ventura 2017), multivariate lexical and lexicogrammatical approaches in these L2s…

In this final article in this guest-edited issue on synergies in second language acquisition and teaching (SLA/T), we attempt to bring together the main content of this issue in an overall, combined synergy statement, concluding this project as a whole. Let us remind readers of the project: A shared effort by 17 scholars taking 11 different…

The study aimed to explore the evidence of first language (L1) mediation in second language (L2) word associations and the L2 learner-related factors affecting the extent of L1 mediation with the following approaches. First, different from previous research, word association tests (WATs) embraced both receptive and productive word associations in…

This article presents a theoretical review of and methodological guidelines for the study of two key notions in second language acquisition research, complexity and difficulty. The term "complexity" has gained considerable currency over the past decades and has taken on a wide range of meanings. We argue for a more restricted…

This study aims to investigate and compare the efficiencies of gamification and ludicization in foreign language learning regarding learning outcome, readiness, engagement, and academic buoyancy. Regarding the theoretical frameworks, gamification and ludicization, feasible in foreign language learning through interaction and problem-solving…

Knowledge of collocations facilitates second language (L2) learning by enhancing accuracy and fluency. However, acquiring L2 collocations is often challenging for learners. One factor contributing to this difficulty is incongruency between first and second languages (e.g., "draw distinctions" in English corresponds to do…

Despite the growing interest in incorporating textual glosses into second language (L2) reading in hypermedia and paper media, no agreements have been reached as to whether and what extent a textual gloss facilitates L2 learners' vocabulary acquisition in hypermedia and paper media. The present study meta-analysed the overall effects of textual…

There has been a great deal of interest in second language vocabulary studies regarding the potential of reading as a source of incidental vocabulary learning. More recently, several studies have also focused on comparing reading with other input modes, such as listening, or reading-while-listening. Among these studies there are two -- Brown et…
