Second language acquisition (SLA) researchers have long searched for patterning in the development of linguistic elements (e.g., grammar and morphology). However, little attention has been given to the examination of systematicity in vocabulary acquisition, limiting our understanding about how overall vocabulary is learnt. The current study…

Research on L2 acquisition of the Spanish perfective and imperfective past has suggested that order-of-instruction (preterite before imperfect) may significantly contribute to learners' difficulty with mastering the imperfect. We sought to empirically test the effect of order-of-instruction by implementing a program-wide intervention in a beginner…

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,…
