Christian Doabler, Ph.D., is a Research Assistant Professor with the Center on Teaching and Learning at the University of Oregon. He specializes in curriculum design, observation systems, and the prevention of learning difficulties. He is a former general education and special education teacher. Currently, he serves as a Co-Principal Investigator on three IES-funded research projects focused on the development and efficacy testing of early mathematics interventions for students who are at-risk for learning difficulties in mathematics: (1) Project ROOTS - A Randomized Control Trial of a Tier 2 Kindergarten Mathematics Intervention,” (2) NumberShire Level-K – “Development of a Game-based Integrated Learning and Assessment System to Target Whole Number Concepts for Kindergarten Students,” and (3) NumberShire Level-2 -Foundations of Mathematical Understanding: Developing a Strategic Intervention on Whole Number.”
