This paper will offer a discussion of the literature concerning multimodality, orchestration and participation related to classroom use of the interactive whiteboard (IWB). Specifically, it will explore the place, or potential use, of the IWB to resource a multimodal approach to teaching and learning, emphasising the complex connections that need acknowledging when viewing the IWB in context. Comments on the IWB's effectiveness or otherwise, however, are beyond the scope of this paper. Conceptions of the role of language in mediating other modes and media, in terms of its centrality or complementarity, will necessarily be addressed by considering activities such as classroom talk aligned to other resources. The role of various actors (including teachers and learners) in designing, orchestrating and interpreting multimodal material will be considered. Whilst recognising the substantial debate regarding multimodality as an analytic lens, the discussion will focus on multimodality in terms of materials used in the classroom. (Contains 2 figures.)
