This paper reports on a design‐based intervention in urban primary and secondary schools serving culturally diverse students from low socio‐economic status (SES) communities. The intervention capitalises on a partially implemented programme in seven schools which use digital devices (netbooks) and applications to raise literacy levels. Learning and teaching measures have been used to identify effective components which can be more systematically implemented. Classroom observations were employed to provide a profile of the use and quality of the literacy instruction and to identify effective instructional practices, thereby contributing to the redesign of instruction for cluster wide implementation. The study adds to a growing number of interventions which use a design‐based approach to tackle problems associated with school effectiveness. It contributes to the identification of promising new practices and to the design of more effective instruction in the context of a national system (New Zealand) that is already generally of high quality in literacy teaching but with low equity. A specific outcome is further evidence about how new technologies and digital learning are being implemented in low SES classrooms and the relationships with valued student outcomes.

This present study reports the impact of a research–practice partnership among nine collaborating schools and researchers in Auckland, New Zealand. The goals of the partnership were to refine digital instruction in ways that would result in improved learning processes and achievement. The partners employed a design-based research approach to iteratively develop and test changes to the pedagogy. Results indicate moderate to large effect sizes in writing, and small effect sizes in reading and mathematics. Results also indicate increasing effects over time in reading and writing, but not in mathematics. Educational effects included greater use of discussions by teachers and greater use of open-ended activity types. These outcomes are discussed in relation to features of the partnership as well as digital pedagogy.
