Research and pedagogical information provided to teachers on implementing explicit strategy instruction has primarily focused on teachers' speech, with limited attention to other modes of communication, such as gesture and artefacts. This interpretive case study investigates two teachers' use of different semiotic resources when introducing second-grade readers to specific reading strategies. We analysed two teachers' use of speech, gesture and artefacts in their introductory explanation of the declarative, procedural and conditional knowledge necessary to be strategic readers. The importance of this article lies in reconciling the narrow focus on what teachers say during explicit strategy instruction with the repertoire of semiotic resources that the teachers actually use to enact multimodal communication during their explanation of the strategy.
