Paired comparison listening tests and circular error rates
نویسندگان
چکیده
On the basis of noises recorded in trains, this article presents circular errors rates obtained by two possible paired comparison methods. The first one allows listeners to answer that two noises in a pair are equally annoying, while the second one forces them to select one of the sounds. It is shown that the latter can lead to very high number of circular errors when perceptual differences between noises are small. Therefore the former method is recommended, and the number of circular errors must be essentially considered as an indicator of the difficulty of the task.

متن کاملEffects of Task-based Academic Listening on High School EFL Students' Listening Comprehension: Does Experiential Learning Style Matter?
Task-based language teaching (TBLT) has been considered as an effective language teaching methodology. However, its applicability for lower-proficiency learners in EFL contexts has not been adequately justified. Moreover, the possible mediating effect of the experiential learning styles on academic listening TBLT has not been targeted in the literature, a gap that this study attempts to fill. T...
