Research has suggested the important role of vocabulary knowledge in second language (L2) speaking proficiency. However, earlier studies tended to disregard the congruence in test format between assessing vocabulary knowledge and speaking skills with the former predominantly measured in written format. The current study measured vocabulary…

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 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 present study examines the effects that a 3-week study-abroad (SA) experience and a set of individual differences have on the foreign language (FL) development of a group of 64 Catalan/Spanish speakers, learners of English as an FL. Moreover, the present study attempts to account for the outcome differences between successful and less…

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…

We report on a small-scale exploratory study of Japanese students' reactions to the use of a bilingual language assistant on an EFL study-abroad course in the UK and we give an insight into the possible effect of using bilingual assistants on speaking production. First-year university students were divided into three groups all taught by a…
