We explore how general principles of learning apply to and combine with usage-based approaches to language learning and teaching, with a focus on the effects of order of exposure to new information in second language (L2) instruction. Although the effects of input spacing and timing on memory and learning have been previously explored (see Rogers,…

The involvement load hypothesis (ILH) was designed to predict the effectiveness of instructional tasks for incidental L2 vocabulary learning. In this meta-analysis we examined 398 effect sizes from 42 empirical studies (N = 4,628) to explore (a) the overall predictive ability of the ILH, (b) the relative effects of different components of the ILH…

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 effects of production and listening training on the subsequent comprehension of foreign-accented speech were investigated in a training-test paradigm. During training, German nonnative (L2) and English native (L1) participants listened to a story spoken by a German speaker who replaced all English /?/s with /t/ (e.g., *"teft" for…

Taking a psycholinguistic orientation within task-based language teaching scholarship, this study investigated the effects of mode (oral vs. written) and task complexity on second language (L2) performance. The participants were 78 Catalan/Spanish learners of English as a foreign language. Half of the participants performed the simple and complex…

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,…

This study investigated the differential effects of prompts and recasts, in the context of dyadic interaction, on the acquisition of grammatical gender by adult second language learners of French. Participants were 25 undergraduate students enrolled in an intermediate-level French course at an English-speaking university. All students were exposed…

The article summarizes results from two experimental studies on reactivity. In the first experiment, 24 college-age participants received a computerized treatment that delivered a grammar lesson, practice, and feedback on assignment of semantic functions in Latin. Verbalizations did not induce reactivity on accuracy, but they slowed down posttest…

Examined the efficacy of the keyword method versus rote rehearsal in learning foreign language vocabulary. Findings revealed that in experienced foreign language learners, rote learners' performance excelled that of keyword learners, whereas in experienced learners, rote and keyword learners recalled the same proportion of words, although the…
