The purpose of the project is that together with teachers, develop a meta-language and an awareness of teaching and assessment in relation to digital, multimodal meaning-making in the classroom to improve the conditions for students' learning in a digital school environment. The goal is to develop models for teaching and assessment, clearly linked to the challenges that teachers identify daily in relation to governing documents, students' skills and classroom practice. Based on socio semiotics and the perspectives of multiliteracies and Designs for learning, teaching design is developed in iterative cycles using the method design-based research in close collaboration with teachers based on the needs identified by the schools. The teaching designs are tested in small-scale classroom interventions. Continuously collected empirical data consists of documentation of workshops, planning discussions with teachers, teaching, teachers’ mutual feedback, and students' digital multimodal text productions. The use of the model Learning Design Sequence, partly as support for the design of learning sequences, and partly as analysis breaks for the empirical material, puts the focus on for and in learning. The research project results are important both nationally and internationally and contribute with knowledge about further development of teaching in digital classroom environments.
