Marit Buset Langfeldt

Marit Buset Langfeldt serves as Senior Lecturer in Mathematics at the Department of Teacher Education, Norwegian University of Science and Technology (NTNU), Trondheim. She instructs primary school teacher training programs in Mathematics 1 (1-7), Mathematics 2 (1-7), and programming-focused courses like LÆR2003, while previously teaching Mathematics 1 (5-10) and continuing education for in-service teachers.

Education:

• Master of Science in Mathematics, NTNU (2016), thesis: "Triangulated Categories and Matrix Factorizations"

Her research investigates mathematical reasoning and argumentation in primary classrooms, emphasizing how teachers facilitate discussions that develop students' proof skills. She examines digital tool integration in mathematics education and pre-service teachers' identity formation through collaborative planning, with active involvement in the ProPrimEd project (2020-2024) developing primary-level reasoning resources.

Publication analysis reveals consistent focus on mathematical argumentation in teacher education, with recent expansion into computational thinking via robotics. Her work bridges theory-practice through resources like ARiL (role-play simulations) and Fuggelmyra (virtual school environment), targeting primary mathematics instruction and teacher development.
