Task Planning and Oral L2 Production: A Research Synthesis and Meta-Analysis
Peer reviewed Peer reviewed
Direct linkDirect link
Johnson, Mark D.; Abdi Tabari, Mahmoud – Applied Linguistics, 2022
Increased second language acquisition (SLA) research interest in the effect of planning on subsequent L2 oral production has typically examined the effect of planning on the syntactic complexity, accuracy, lexical complexity, and/or fluency (CALF) of L2 production. However, the results of research in this domain are inconclusive. This study, a…

Vandommele, Goedele; Van Gorp, Koen; Van den Branden, Kris; De Maeyer, Sven – Applied Linguistics, 2022
This study investigates the differential effects of a task-based inside-school intervention and an outside-school project intervention on the development of speaking skills of 56 beginner second language (L2)-learners. The study extends previous research by looking at development across multiple occasions instead of two (i.e., a pretest and…

The Effects of Complexity, Accuracy, and Fluency on Communicative Adequacy in Oral Task Performance
Peer reviewed Peer reviewed
Direct linkDirect link
Révész, Andrea; Ekiert, Monika; Torgersen, Eivind Nessa – Applied Linguistics, 2016
Communicative adequacy is a key construct in second language research, as the primary goal of most language learners is to communicate successfully in real-world situations. Nevertheless, little is known about what linguistic features contribute to communicatively adequate speech. This study fills this gap by investigating the extent to which…

Dynamics of Complexity and Accuracy: A Longitudinal Case Study of Advanced Untutored Development
Peer reviewed Peer reviewed
Direct linkDirect link
Polat, Brittany; Kim, Youjin – Applied Linguistics, 2014
This longitudinal case study follows a dynamic systems approach to investigate an under-studied research area in second language acquisition, the development of complexity and accuracy for an advanced untutored learner of English. Using the analytical tools of dynamic systems theory (Verspoor et al. 2011) within the framework of complexity,…

Contrasting Effects of Starting Age and Input on the Oral Performance of Foreign Language Learners
Peer reviewed Peer reviewed
Direct linkDirect link
Muñoz, Carmen – Applied Linguistics, 2014
The present study focuses on the influence of starting age and input on foreign language learning. In relation to starting age, the study investigates whether early starters in instructional settings achieve the same kind of long-term advantage as learners in naturalistic settings and it complements previous research by using data from oral…

Towards an Organic Approach to Investigating CAF in Instructed SLA: The Case of Complexity
Peer reviewed Peer reviewed
Direct linkDirect link
Norris, John M.; Ortega, Lourdes – Applied Linguistics, 2009
In this article, we examine current practices in the measurement of syntactic complexity to illustrate the need for more organic and sustainable practices in the measurement of complexity, accuracy, and fluency (CAF) in second language production. Through in-depth review of examples drawn from research on instructed second language acquisition, we…
