摘要：With digital technology it has become possible and relatively easy to create texts, which contain different kinds of expression, such as images and sound. This challenges the concept of literacy and what it means to create texts in education. By exploring tensions and contradictions in and between different components in the activity system of creating texts in classrooms this article attempts to illuminate conditions for transforming this activity. Activities are here conceptualized as activity systems where components at local and systemic levels influence and constitute each other. Tensions and contradictions at both levels, reflect general issues related to the concept of literacy, as they concern what kind of expressions are considered valuable and primary when creating and assessing texts in educational settings
