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…

This systematic review aims to explore how task complexity and task sequencing affect the complexity, accuracy, and fluency (CAF) of second language performance. Through an analysis of studies conducted between 2012 and 2021, this review investigates the characteristics of the studies, operationalisation of task complexity, measurements of CAF,…

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,…

This exploratory study investigated Vietnamese secondary students' engagement in a sequence of detecting, correcting, and rewriting tasks, and examined the factors affecting their engagement and/or disengagement in the process. The study draws on the principles of task-based instruction, involving eight mixed-ability groups (n = 31), and was…

To test the predictive power of the SSARC (stabilize, simplify, automatize, reconstruct, and complexify) model of pedagogic task sequencing in second language (L2) writing development, the present study explores the performance of written decision-making tasks with varied levels of cognitive complexity in a simple-to-complex sequence in comparison…
