Situated within Sociocultural theory (SCT), this article analyzed an existing data set (Toth, 2021a, 2021b, 2021c, available at https://www.iris-database.org) to investigate learners' development through participation in a dialogic approach to grammar instruction called PACE. The target of instruction was the Spanish pronominal clitic…

This article focuses on the role of crosslinguistic patterns with verbs in the mapping of noun phrases/semantic roles to positions in morphosyntax, with a particular focus on second language (L2) development of Spanish "se." The data set derives from high school learners of Spanish in the United States under broadly deductive and…

This longitudinal randomized trial study investigated the effects of phonological specificity training on second language (L2) vocabulary learning. Eighty-six Dutch secondary-school students participated in one of two experimental conditions or in an animacy judgment (active control) condition. Participants in the phonological specificity training…

This study investigated the relative effectiveness of two instructional interventions (implicit and explicit feedback) as a function of implicit sequence-learning ability. Second language (L2) attainment was measured by means of a self-paced reading task, which shows online sensitivity to language errors. Implicit sequence-learning ability was…

Adequately responding to linguistic diversity in the classroom is imperative in European school contexts, not least because of current migratory movements. This article presents the results of an intervention study with primary school English-foreign-language learners in Germany (N = 42, M[subscript age] = 8.70 years) from linguistically diverse…

The current study was designed to assess the central claim of the Teachability Hypothesis (TH), a corollary of general Processability Theory (PT), which predicts instruction cannot alter posited universal, hierarchically organized psycholinguistic constraints behind PT's developmental sequences. We employed an interventional design, which adhered…

This descriptive observational study aimed at exploring the form-focused instruction (FFI) interventions used by four French and four English as-a-second-language high school teachers to draw their students' attention to form. With the help of an Intervention-on-Form(s)-Observation Scheme (IFOS) developed and tested for this purpose, each FFI…

Research on the effects of second language strategy instruction (SI) has been extensive yet inconclusive. This meta-analysis, therefore, aims to provide a reliable, quantitative measure of the effect of SI as well as a description of the relationship between SI and the variables that moderate its effectiveness (i.e., different learning contexts,…

Sixty-five Japanese learners of English participated in the current study, which investigated the acquisitional value of form-focused instruction (FFI) with and without corrective feedback (CF) on learners' pronunciation development. All students received a 4-hr FFI treatment designed to encourage them to notice and practice the target feature of…

Second language listening has historically proved to be a difficult skill. Strategy instruction studies have sought to bring about improvements in subjects' listening but with mixed results. This lack of success might be due to the nature of listening strategy theory and its influence on conceptualizations of listening strategy instruction. The…

Research on second language lexical development during reading has found positive effects for word frequency, the provision of glosses, and elaborative word processing. However, findings have been inconclusive regarding the effect of such intervention tasks on long-term retention. Likewise, few studies have looked at the cumulative effect of…
