Abstract
This study explores an analysis unit suitable for listening recall. It follows Iimura (2007) and focuses on idea unit (IU). It examines three types of IUs-Carrell version, Sakai version, and Spencer version. The recall protocols of 41 Japanese university students are scored against these types. Their scores on each type are compared to an external criterion measure, the listening section of the computerized assessment system for English communication (CASEC). Although the results indicate that all the versions are significantly correlated with the external measure, by grouping recall protocols, this study reveals the characteristics of each type and identifies Sakai version to be the most suitable analysis unit for the listening recall of the three IU types.
