Title:

Opportunities for Instrumental Genesis in Mathematics Lessons

Digital technologies have become ubiquitous in mathematics classrooms. However, there are still many aspects of technology use and integration that are not well understood. One such topic is instrumental orchestration, which is the process by which teachers support students’ learning of mathematics with and through technological tools. This exploratory study extends prior research on instrumental orchestration by analyzing a sample of videos found on teacher professional development websites. In addition to identifying six literature-based categories of instrumental orchestration, the analysis revealed five new categories; extended by teachers as well as peers to support student learning. We discuss implications of this analysis for research and teacher education.
