Purpose: This follow-up study examined whether a parent intervention that increased the diversity of lexical noun phrase subjects in parent input and accelerated children's sentence diversity (Hadley et al., 2017) had indirect benefits on tense/agreement (T/A) morphemes in parent input and children's spontaneous speech. Method: Differences in…

This quasi-experimental study examined the potential benefits of zero-error dictation, a teaching technique based on dialogue-driven dictation, and the extent to which target linguistic features and proficiency levels mediated its effects on second language (L2) learners' accurate use of French grammatical morphology. Seventy-nine learners of L2…

Background: Currently, most research on the effective treatment of morphosyntax in children with specific language impairment (SLI) pertains to younger children. In the last two decades, several studies have provided evidence that intervention for older school-age children with SLI can be effective. These metalinguistic intervention approaches…

This study investigated the metalinguistic reflections of 12 students, aged 14-15 years, undertaking a unit of work focused on reading and writing non-fiction. The unit embedded contextualised grammar teaching into preparation for English Language examinations. Students were interviewed twice, with prompts to discuss a sample of argument text in…

Whilst historically there has been a widespread consensus that teaching grammar has no impact on students' attainment in writing, more recent research suggests that where a functionally oriented approach to grammar is meaningfully embedded within the teaching of writing, significant improvements in writing can be secured. A recent study, using a…

This study examined the use of "Pixton" for enhancing grammar and vocabulary teaching in a public high school in the South region of Ecuador. In this intervention, 163 junior high school learners and 14 pre-service English teachers participated during a period of 4 months. The data for this study was obtained by gathering information…

Purpose: The current study used an intervention design to test the hypothesis that parent input sentences with diverse lexical noun phrase (NP) subjects would accelerate growth in children's sentence diversity. Method: Child growth in third person sentence diversity was modeled from 21-30 months (n = 38) in conversational language samples obtained…

A quasi-experimental study was conducted to examine the effectiveness of providing written corrective feedback (WCF) to Arab speakers of English on ten uses of English prepositions. Arab speakers commonly find it difficult to correctly use English prepositions, mainly due to the differences between the two languages (e.g. Ortega, 2009). Examples…

Students with writing difficulties and learning disabilities struggle with many aspects of the writing process, including use of sentence-level skills. This literature review summarizes results from 19 published articles that used single-case or group-experimental and quasi-experimental designs to investigate effects of intervention on the…

Corrective feedback (CF), the implicit or explicit information learners receive indicating a gap between their current, compared to the desired, performance, has been an area of interest for EFL researchers during the last few decades. This study, conducted on 139 English-major prospective EFL teachers, assessed the impact of two CF types…

Despite substantial correlational evidence of a relationship between morphological awareness and reading ability, there has been only limited intervention research conducted to document the effects of morphological awareness on various literacy outcomes, particularly reading comprehension, and almost no research comparing the relative…

One important controversy connected with the effectiveness of grammar teaching seems to have been resolved as there is ample empirical evidence testifying to the positive effect of form-focused instruction on second language acquisition (Nassaji & Fotos, 2004; Norris & Ortega, 2000; Spada, 1997, 2010). Nevertheless, there are still a…

This study examined the effectiveness of a bilingual/bicultural technology intervention on beginning learners of Spanish at a public university in the United States and intermediate learners of English at a public university in Mexico. This study used a quasi-experimental mixed method design and compared gains in grammar, listening, and reading…

Recently ELT has witnessed the debate between the proponents of non-interventionist and interventionist views towards SLA. The former, also known as zero option, sees L2 acquisition as an incidental process leaving no role for instruction (Krashen, 1981; Prbhu, 1987), while the latter considers instruction effective and even crucial for some…
