It is important to be able to identify research results likely to have been arrived at by means of "'p'-hacking," a common term for research and reporting practices (such as the selective reporting of results) that are biased toward finding "p" < [alpha]. This paper discusses and demonstrates "'p'-curving," a means…

This is the first international and interdisciplinary handbook to offer a comprehensive and an in-depth overview of findings from contemporary research, theory, and practice in early childhood language education in various parts of the world and with different populations. The contributions by leading scholars and practitioners are structured to…

Lexical knowledge is complex, multidimensional, and difficult to pin down to a set of defined components. The development, organization, and use of lexical knowledge in the first and additional languages are studied in a number of neighbouring disciplines beyond second language acquisition and applied linguistics, including psycholinguistics,…

Exploring the longitudinal development of second language (L2) lexical use has been one of the important topics in L2 vocabulary research. One approach to examining longitudinal changes in L2 lexical use is to capture changes in lexical features as found in learner production, such as L2 writing, over time. To further facilitate this approach, the…

In this brief report, we present a scoping review of 31 second language (L2) vocabulary research syntheses published in the Web of Science from January 1990 to May 2022. The purpose of this undertaking was to understand what L2 vocabulary research synthesizers have aggregated and the investigative foci they intended to address. It was observed…

There has been a growing number of reviews of mobile language learning (MLL) conducted on various aspects of this field of study over the last two decades. However, unlike in other fields, there is a paucity of overviews of reviews that assess and integrate findings from multiple reviews, and that compare and contrast such findings, or establish…

Since its modern inception in the late nineteenth century, research on word associations has developed into a large and diverse area of study, including work with both applied linguistic and psycholinguistic orientations. However, despite significant recent interest in the use of word association to investigate second language (L2) vocabulary…

This book is unique in bringing together studies on instructed second language acquisition that focus on a common question: "What renders this research particularly relevant to classroom applications, and what are the advantages, challenges, and potential pitfalls of the methodology adopted?" The empirical studies feature experimental,…

This paper reviews the literature on the use of digital simulation games in computer-assisted language learning (CALL). The discussion explores research approaches, contexts, methodologies, findings, trends and issues in peer-reviewed research that has investigated the use of this type of digital game over the period 2005 to 2020. Results showed…

This systematic review presents a definition for digital games within the second/foreign language (L2) learning research field. This definition is used to identify games used in research in the last five years (2012-2017). Forty-nine studies were identified and then summarized by type of research, game genre employed, age, and size of sample…

This is the appendix for the report, "The Impact of Word Knowledge Instruction on Literacy Outcomes in Grade 5." District leaders in a large urban school district in central Florida wanted to examine the efficacy of a new curriculum designed to enhance the word knowledge of grade 5 students so as to improve reading achievement. The new…

The digital technology-mediated foreign language vocabulary learning involves the use of technological tools such as online and offline dictionaries, multimedia, social media, television, computer, smart-phones, tablets, and similar others. Although many research findings in the existing literature have emphasized the effectiveness of these…

We meta-analyzed the effectiveness of incidental second language word learning from spoken input. Our sample contained 105 effect sizes from 32 primary studies employing meaning-focused word-learning activities with 1,964 participants with typical cognitive functioning. The random-effects meta-analysis yielded a mean effect size of g = 1.05,…

The purpose of this study was to systematically review the factors affecting the language, speech intelligibility, speech production, and lexical tone development of children with hearing loss who use spoken languages other than English. Relevant studies of children with hearing loss published between 2000 and 2011 were reviewed with reference to…

Despite the hundreds of Mobile-Assisted Language Learning (MALL) publications over the past twenty years, statistically reliable measures of learning outcomes are few and far between. In part, this is due to the fact that well over half of all MALL-related studies report no objectively quantifiable learning outcomes, either because they did not…
