Teacher collaboration helps to facilitate meaningful and effective learning and enables sustainable development of schools. Teacher teams who collaboratively investigate a shared problem, or design curriculum materials together, significantly contribute to the professional development of teachers in areas of subject matter, curriculum design and data skills.

Contributions to this book discuss various perspectives of teachers collaborating in design teams, by investigating the sense of collaboration and its effects, and the conditions that influence and drive it. The studies provided suggest that collaborative design and research supports participants (teachers and teacher educators) to improve their knowledge, specifically in regards to technological pedagogical content and subject matter. Participating teachers further developed curriculum design expertise, such as, understanding the relevance and effectiveness of involving stakeholders in designing and implementing newly designed curricula. This volume was originally published as a special issue of Educational Research and Evaluation.
