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…

Studies into the role of audiovisual input and captions (i.e., subtitles in the same language as the audio) for L2 learning have shown that such input can positively influence L2 learners' acquisition of lexical items. Few studies have explored the effects of captioning on learners' capacity to segment the speech stream. This study investigates…

This book contributes to emerging research on third language acquisition (TLA) and pinpoints the main factors characterising TLA as a different process and area of study from second language acquisition. Moving beyond the dichotomous conception of monolingualism and bilingualism, it proposes a holistic and interdisciplinary approach to studying…

Language is crucial for adapting to society, and learning different languages enhances human efficiency. Learning a second language involves acquiring any language in addition to one's native language. Second Language Acquisition (SLA) has two meanings, generally, it describes the process of learning a second language, and more specifically, it…

Purpose: This meta-analysis study aimed to determine the optimal level of talker variability in training to maximize second-language speech learning. Method: We conducted a systematic search for studies comparing different levels of talker variability in nonnative speech training, published through July 2024. Two independent reviewers screened…

Second language acquisition (SLA) researchers have long searched for patterning in the development of linguistic elements (e.g., grammar and morphology). However, little attention has been given to the examination of systematicity in vocabulary acquisition, limiting our understanding about how overall vocabulary is learnt. The current study…

Written corrective feedback is a hot topic in the field of L2 writing and second language acquisition. Citespace, one of the bibliometric analysis software, was used to investigate the number of publications, productive authors, influential journals and institutions, major themes, and research trends of written corrective feedback in L2 writing…

Background/purpose: This study examines how well EFL students perform in English language learning using Kagan's Cooperative Learning Approach (KCLA). Conventional teaching approaches frequently fail to actively involve students, which lowers achievement. With an emphasis on teamwork and active engagement, this study seeks to ascertain whether…

The purposes of this research were to: 1) develop and determine the efficiency of the digital learning according to blended learning on Chinese languages for beginner level in primary school, 2) compare the students' learning achievement test after using the digital learning according to blended learning on Chinese languages for beginner level in…

Spanish is the second most common language among US children aged 5-17, with 26.8% speaking it at home. To foster cultural understanding and promote positive relationships, it's crucial to introduce young children to different languages and cultures. Preschool language education can cultivate respect and empathy, building more inclusive…

This paper presents the outcomes of an action research study that implemented a linguistic landscape (LL) unit as an English language learning activity at the secondary school level in Rayong, Thailand. The theoretical framework employed in this study draws upon Lefebvre's (1991) conceptualization of space, adapted for pedagogical purposes as…

Learning a foreign language enables people to get to know different cultures. People who know different cultures get richer. So, their prejudices against people are destroyed. Thus, a foreign language student may both improve himself and become a better person. In this context, the aim of the present study is to learn the thoughts of Turkish…

While it is widely accepted that language teachers require knowledge of second language acquisition (SLA) (Richards, 2010), what about content teachers, who are increasingly required to help develop their learners' academic language proficiency? How much do they need to know about SLA theories and how can they acquire such knowledge and expertise?…

This meta-analysis included 27 empirical studies to explore the effectiveness of robot-assisted language learning (RALL) as well as the moderating effects of a number of variables. The comparison of 64 effect sizes from 2,637 participants indicated significant variability between the independent samples. The overall results showed that the…

Counterfactuals are a type of conditional sentences used to convey situations that do not correspond to reality. Tense morphology is a core ingredient to encode counterfactuals in English and most Indo-European languages. Mandarin Chinese (hereafter Chinese) lacks tense morphology and does not require counterfactuals to be formally distinguished…
