There has been extensive investigation into factors affecting digital technology integration in learning and teaching, but the complexity of integration continues to elude understanding. Thus, questions about how digital technologies can be best used to support learning persist. This paper argues that methods designed to address complex systems are needed to understand the interplay between teaching, learning and digital technologies. Starting with a developing system model of teachers' technology integration, this study revises the model to include factors of students' experience using digital technologies and beliefs about learning. The revised model is then used to demonstrate possible effects of student experiences in a technologically integrated group learning task. Analysis draws on data from a large-scale Australian study of technology innovation (N=7406). Data mining techniques are used to identify patterns of students' technology use and perceptions of group work. Findings inform revision of the model to include factors of students' experience and learning and their effects on teachers' practice. Implications for learning design and students' learning experiences are explored.
