Dr. LeSage’s research areas explore the inter-connectedness of teaching and learning mathematics from preschool through teacher professional development, including affect and cognition. Current projects include research on pre-service teachers’ mathematical knowledge and teaching efficacy; mobile apps as tools to support and elicit Kindergarten children’s understanding of numeracy; and video podcasts as a tool to support flipped classrooms.
