ABSTRACT
This chapter describes the development of tracking semiosis as a method for revealing evidence of the choices inherent in students' representational activity. It begins by demonstrating the operation of representational processes in multimodal texts using two student-produced artefacts central to this study, a three-dimensional model and a poster. After providing an account of the different representational processes, the tracking semiosis framework is presented and its format explained: a grid-like arrangement of chronologically ordered multimodal texts grouped according to a common representational process. Two examples of tracking semiosis are then used as illustrations, one from the teaching of science and one from history.
