Integration of technology in schools rests on effective teacher education programmes that help teachers create new teaching and learning methods and adopt them for classroom use. Social learning processes play a key role in this, but there is a lack of understanding of their role in technology adoption and in evidencing them in teacher education programmes. Using the knowledge appropriation model, we propose a self-report questionnaire instrument to evidence knowledge creation and learning practices during training. With a sample of N = 109 in-service teachers participating in the Teacher Innovation Laboratory, a teacher professional development programme that is built around school-university co-creation partnerships, we demonstrate the instrument to be reliable and to differentiate between groups who completed different programmes. The instrument predicted intended adoption of technology-enhanced learning methods beyond individual level constructs, highlighting the important role that social practices play for the eventual adoption of technologies in the classroom.
