Roser’s current research focuses on understanding how students make sense of mathematics in the context of the classroom, with a focus on classroom discourse developed through the interaction of students, teacher, and curriculum artifacts. She brings academic expertise in the following areas: methods of teaching mathematics at the secondary school level; mathematics professional development for teachers; discourse analysis for understanding meaning making in mathematics; socio-cultural theories and their appropriation in the learning of mathematics.
Courses taught at Lesley include Calculus I and II; Discrete Mathematics; Inferential Statistics; Patterns and Functions; Teaching Middle and Secondary Mathematics: Exploring Connections; Teaching Mathematics for Elementary School Teachers; Geometry Measurement and Data; Curriculum, Instruction and Assessment in Mathematics; Teaching Mathematics in a Student-Centered Secondary Classroom; Constructing Mathematical Understanding for Number Theory.
