Abstract
Based on the multimodal discourse analysis, the contribution attempts to describe the genre of online video tutorial, focusing primarily on the involved modes and their interplay. The research has been done on the corpus consisting of online video tutorials on differential and integral calculus (e.g. first-order linear differential equations) which are available on the Internet and made by native speakers of English. In order to comment on differences between online and offline practices a referential group of standard lectures on infinitesimal calculus has been investigated as well. A case study focusing on forms of explication from the multimodal perspective has been carried out; seven presentational formats were compared both quantitatively and qualitatively to find out how various communication techniques are employed.
