This article examines the effects of test format and task type on candidate output in direct and semi-direct versions of the oral interaction subtest of the access: test (the Australian Assessment of Communicative English Skills). Specifically, it contrasts the degree of 'orality' versus 'literacy' characterizing the audiotaped samples collected for the study from the perspective of lexical density, which provides a measure of the relationship between lexical and grammatical items in spoken or…

Systematic effects in the rating of second-language speaking ability: test method and learner discourse
Major differences exist in two approaches to the study of second-language performance. Second-language-acquisition (SLA) research examines effects upon discourse, and is typically unconcerned with

A variationist, corpus linguistic analysis of lexical richness in Flanders
A number of tests have been developed for measuring the lexical knowledge and use of language learners (see for example Read 2000). Most of these tests focus on child language acquisition or on the
An investigation of planning time and proficiency level on oral test discourse
The inclusion of planning time in semi-direct oral interaction tests adds consider ably to the overall length of the test, and it is important to be clear that the increase in length is justified by
The Role of Repair in Oral Fluency and Disfluency
In the literature on second language oral fluency, the most commonly used measures are temporal variables, based on speech rate and pausing (Lennon 1990). However, repair is also a key aspect of
