Multisite research (MSR) offers the key advantages of greater statistical power and external
validity via larger and more diverse participant pools. In second language acquisition (SLA) …

Meta-analyses play an instrumental role in informing second language (L2) theory and
practice. However, current (ie, classic) approaches to meta-analysis are limited in their …

Applied linguists are increasingly conducting meta-analysis in their substantive domains,
because as a quantitative approach for averaging effect sizes across studies, it is more …

Meta-analytic reviews collect available empirical studies on a specified domain and
calculate the average effect of a factor. Educators as well as researchers exploring a new …

Meta-analysis has become increasingly popular in second language acquisition research
(SLA) and has provided valuable summative information about a number of key areas …

This chapter proposes that the emergent multiphase design can be conceptualized as an
integrated mixed methods approach for conducting language research. There has been …

Research synthesis and meta‐analysis provide a pathway to bring together findings in a
given domain with greater systematicity, objectivity, and transparency than traditional …

Second language acquisition researchers often face particular challenges when attempting
to generalize study findings to the wider learner population. For example, language learners …

This study provides a systematic review of the methodological features of meta-analyses in
second language learning. The synthesis aims to inform how meta-analyses in L2 learning …

There has recently been a surge of interest in improving the replicability of second language
(L2) research. However, less attention is paid to replicability in the context of L2 meta …
