Previous research has shown that task repetition can positively affect L2 oral performance. However, few studies have explored the effects of task repetition on young EFL learners' production. Also, task repetition research has paid little attention to effects of "spacing" examined through longer time intervals between the two occasions…

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,…

Despite extensive research on task planning in L2 writing contexts, the optimal length of pre-task planning time remains uncertain due to varying lengths used in TBLT studies. This study aimed to address this gap by investigating the effects of different pre-task planning times (nil, 5, 10, and 15 minutes) on the argumentative writing task…

Many English as a foreign language (EFL) learners worldwide spend hours playing commercial-off-the-shelf massively multiplayer online games. They engage in a multitude of different interactions with the game environment and possibly with other gamers, using English as the predominant medium of communication. This raises the question of whether…

The current study explores whether form-focused instruction with different timing and availability conditions can be used with repetitive writing tasks to enhance grammatical accuracy and fluency. Sixty-one intermediate English as a foreign language (EFL) learners performed three text reconstruction tasks: Task 1, Repeat Task, New Task, and…

This study examines the influence of pre-departure proficiency on English as a second language (L2) oral development after a semester studying abroad in two distinct learning contexts. The data analysed were collected from tertiary level students (N = 33) who undertook an ERASMUS exchange semester in a European country where English was either the…

This study investigates the impact on L2 oral performance of participatory structure of strategic planning (individual vs. collaborative pair planning) and task complexity (simple vs. complex tasks) defined according to the number of elements involved. It also explores individual and collaborative planners' planning behaviours prior to simple vs.…

This study aimed to examine the effects of combining task repetition with immediate post-task transcribing (TRIPT) on L2 learners' immediate and delayed oral repetitions of the same task in terms of complexity, accuracy, and fluency (CAF). For this purpose, 38 intermediate Iranian learners were randomly assigned to two groups: TRIPT and task…

This article expands upon research into task planning effects by looking at how the addition of planning prior to group discussions may positively and negatively influence performance. 24 Japanese university students performed three weekly discussions in groups of four. Prior to each discussion, they undertook either no planning, strategic…

This study examined the effect of the combination of task repetition and post-task transcribing (TRPT) on the complexity, accuracy, and fluency (CAF) of L2 oral performance and their subsequent development. Taiwanese university students (N = 39) were randomly assigned to one of the three groups: TRPT, task repetition (TR), and control group, and…

While there is ample evidence that study abroad (SA) enhances oral fluency in a foreign language, the effects of different types of learning context on other aspects of oral skills, such as vocabulary use, have not received much attention in academic research and are less clear. The present study tries to fill this void by investigating lexical…

The study presents an investigation of the effect of strategic planning, online planning and rehearsal on the fluency, accuracy and complexity of oral productions at two proficiency levels. Forty EFL participants at low and intermediate levels performed picture story tasks in three different conditions: the online planning only condition,…

The constructs of complexity, accuracy and fluency (CAF) have been used extensively to investigate learner performance on second language tasks. However, a serious concern is that the variables used to measure these constructs are sometimes used conventionally without any empirical justification. It is crucial for researchers to understand how…

This article discusses issues related to oral assessment of school knowledge of L2-educated students. In particular, it examines benefits and disadvantages of students being tested in their L1 (their dominant language) and in their L2 (their language of instruction). The study draws on the data from 37 high school students studying in a content…

This study investigates the combined effects of task-based careful online planning and the storyline structure of a task on second language performance (complexity, accuracy and fluency). Sixty intermediate EFL learners were randomly assigned to four groups (n = 15). Participants were asked to perform two tasks with different degrees of storyline…
