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,…

Although a modality effect indicating better learning from an animation with spoken learning guidance than from an animation with written learning guidance has often been found in research on learning from animation, the effect has hardly been investigated for learning from computer simulation. This study examined the interaction effects between…

Teachers spend a lot of time finding 'just right' picture books for their students. However, much of what is known about a book's difficulty level was developed with native English speakers. More needs to be developed with the distinctive characteristics of English Learners (ELs). This study reports on the selection of picture books to teach in an…

This paper investigated how production task combined with teacher feedback (in the form of recasts) affects child second language development, and the effects of task complexity on their production performance. 92 child learners of English in three intact classes were assigned to three tasks of different complexity (simple, +complex, ++complex).…

The research investigated pragmatic transfer in responses to English tag questions by L1 Thai learners based on Interlanguage Pragmatics, specifically pragmatic transfer (Kasper & Blum-Kulka, 1993). The L1 Thai learners were categorized into two groups according to their English proficiency levels: advanced and intermediate. Oral and written…

This study investigated the effects of task complexity on child learners' second language (L2) gains, the relationship between aptitude and L2 development, and the extent to which task complexity influences this relationship when recasts are provided. Sixty child EFL learners were assigned to two experimental groups. During the treatment, one…

The aim of this study was to investigate the effects of cognitive task complexity and individual differences in input, processing, and output anxiety (IPOA) on L2 narrative production. The participants were enrolled in a bilingual secondary educational program. They performed two narrative tasks in speech and writing. The participants' level of…

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…

The authors assessed 4,865 middle and high school students for the ability to recognize and understand written and spoken morphologically simple words, morphologically complex words, and the syntactic structure of sentences and for the ability to answer questions about facts presented in a written passage and to make inferences based on those…

The study reported in this paper investigated the relationship between components of aptitude and the fluency, lexical variety, syntactic complexity, and accuracy of performance in two types of written and spoken narrative tasks. We also addressed the question of how narrative performance varies in tasks of different cognitive complexity in the…

The research project reported in this chapter consists of three studies in which syntactic complexity, lexical variation and fluency appear as dependent variables. The independent variables are task complexity and proficiency level, as the three studies investigate the effect of task complexity on the written and oral performance of L2 learners of…

The ultimate goal of reading is to construct text meaning based on visually encoded information. Essentially, it entails converting print into language and then to the message intended by the author. It is hardly accidental, therefore, that, in all languages, reading builds on oral language competence and that learning to read uniformly requires…

Indicates that, in relation to oral systems, written systems are more complex in structure, reveal more adjectival but less adverbial elaboration, show more complex verbal structures, and contain fewer indices of personal reference. (RL)

This study investigated the development of oral metalinguistic abilities in 140 children (ages 5-12) with oral language or reading impairments. The study focused on determining the difficulties that children with these different types of problems have at different ages in the elementary school years and determining how metalinguistic abilities…

The manual for administration of the Chinese Proficiency Test contains an overview of the program, including: (1) its history, content, and format; (2) its primary focus and uses; (3) administration procedures, including registration, ordering the test, reporting scores, and billing; (4) the interpretation of test scores based on normative data…
