Student engagement in the process of transduction concomitantly affords them with opportunities to develop and express their critical and creative thinking competences. Reconfiguring or remaking knowledge or meaning in modes other than those of the original sources of information requires affective, imaginative and cognitive activity by sign-makers. In this article, I present examples of elementary students' transduction work and discuss their semiotic meaning-making with reference to the concepts of critical and creative thinking. During the study featured in this article, Grade 4 students engaged in the process of transduction when participating in activities about elements of visual art and design and conventions of the medium comics, when exploring picturebooks and graphic novels and when composing and explaining their own multimodal texts. The students' transmodal meaning-making showed how, in the context of the research classrooms, the purposefully designed pedagogy and activities both required and nurtured students' critical and creative thinking, which simultaneously provided the students with opportunities to extend their knowledge and deepen their understandings of the concepts and curriculum content under study.
