Extensive reading has been continuously studied as a promising instructional method for improving students' language proficiency, including reading proficiency, vocabulary acquisition, and grammar awareness. The present study is a meta-analysis, which synthesized the data of 21 empirical studies (N = 1268). It was designed to explore whether…

Ensuring internal validity in quantitative research requires, among other conditions, reliable instrumentation. Unfortunately, however, second language (L2) researchers often fail to report and even more often fail to interpret reliability estimates beyond generic benchmarks for acceptability. As a means to guide interpretations of such estimates,…

The interaction between heritage language (HL) and ethnic identity has gained increasing scholarly attention over the past decades. Numerous quantitative studies have investigated and vindicated this interaction within certain contexts. Nevertheless, quantitative evidence on this interaction across contexts is absent to date. The current…

Lexical bundles are worthy of attention in both teaching and testing writing as they function as basic building blocks of discourse. This corpus-based study focuses on the rated writing responses to the email tasks in the Canadian English Language Proficiency Index Program® General test (CELPIP-General) and explores the extent to which lexical…

Elicited imitation (EI) has been widely used to examine second language (L2) proficiency and development and was an especially popular method in the 1970s and early 1980s. However, as the field embraced more communicative approaches to both instruction and assessment, the use of EI diminished, and the construct-related validity of EI scores as a…

Low language proficiency and problem behavior often co-occur, yet language deficits are likely to be overlooked in children with emotional and behavioral disorders (EBD). Random effects meta-analyses were conducted to determine prevalence and severity of the problem. Across 22 studies, participants included 1,171 children ages 5-13 with formally…

Sixteen meta-analyses were conducted to examine relations of typically developing bilingual immigrant-background children's oral language proficiency in their first and second language with the school outcomes of early literacy (k = 41), reading (k = 61), spelling (k = 9), mathematics (k = 9), and academic achievement (k = 9). Moderate to strong…

The ever growing interest in the development of foreign or second (L2) oral proficiency in a computer-mediated communication (CMC) classroom has resulted in a large body of studies looking at both the direct and indirect effects of CMC interventions on the acquisition of oral competences. The present study employed a quantitative meta-analytic…

As various means of computer mediated communication (CMC) have been incorporated within language classrooms over the past two decades, it has become important to critically understand whether, to which extent, and under what contextual factors, a particular type of CMC is more effective than other modes of communication. This study examined the…

This research project undertook a review and synthesis of previous research on the effectiveness of feedback for individual writing development. The work plan was divided into two main phases. First, we surveyed all available studies that have investigated the effectiveness of writing feedback, including both quantitative and qualitative research,…

A review of research leads to the proposal that infants' perception of "fragile" contrasts is lost due to their lack of exposure to particular sounds. Perception of "robust" contrasts is lost around the onset of formal language training due to children's lack of experience with phonologically irrelevant sounds. (Author/CB)

Quantitative educational research with ethnic minorities has a long history, characterized by assumptions that are still operative, such as the assumption that the white male is the standard against which other groups should be compared. It has also been assumed that assessment instruments are applicable across all groups, and that sources of…

Two studies of elementary, intermediate, and advanced second language learners indicated that involuntary rehearsal of second languages ("Din in the Head") is more frequently experienced by elementary and intermediate students and much less prevalent among advanced students, suggesting that the phenomenon is related to language…
