This interpretive case study investigated how a fifth-grade teacher’s social practices with visual and linguistic signs positioned her students (10- and 11-year-olds) to take up particular modes as they constructed digital compositions. The context of the study was a suburban public school in the northeastern United States. Analysis was threefold. The discourse surrounding multimodal composition was analyzed via inductive analysis. Students’ use of semiotic resources in the HyperStudio composition was analyzed with Unsworth’s image-language intermodal framework. Then, teacher-student conversations related to visual and linguistic signs were triangulated with students’ compositions. Findings show that a classroom teacher’s limited content knowledge as related to metafunctions and metalanguage of visual and linguistic sign systems affected the information taught to the students and, ultimately, their use of visual and linguistic signs. Students demonstrated tacit knowledge of image-language relations beyond what was taught but lacked the explicit knowledge to more strategically use visual and linguistic signs. Implications include the importance of creating opportunities for teachers to develop more substantive content knowledge of the metalanguages and metafunctions of various sign systems.

Teachers and students often express an aversion to poetry based on their experiences with printbased poetry texts that typically dominate school curricula. Given this challenge and the potential affordances of new and multimodal technologies, we investigate how preservice and inservice teachers enrolled in a new literacies master’s course began to interpret poetry multimodally, through PowerPoint.
