In recent years increasing research attention has been devoted to the definition and development of presentation skills. As an interactive oral discourse type, the presentation is characterised by specific speech acts, of which cooperative acts have proved to be of a highly developmental nature (Sazdovska, 2009). The aim of the present paper is to report on a study which investigated the metadiscursive realisations of interactional acts in English major novice presenters' speeches as well as their correlation with raters' holistic perceptions of presentation quality.
