I am a senior lecturer at Mid Sweden University.

One of my research interests is how students’ mathematical reasoning influences their learning
in primarily mathematics, but also in physics. This has been expanded to include studies of how
various contexts in mathematics tasks influence students’ mathematical reasoning.

Another interest is how students’ understanding of mathematical symbols might affect their mathematical
reasoning, which include interest in how mathematical symbols can be understood, with a specific focus
on algebraic symbols, and the role of mathematical discourses.

Transition between different educational levels is known to include changes in mathematical discourses,
thus my research also includes transition studies and interest in what happens to students’ mathematical
reasoning in the transition.

Primary focus has so far been on upper secondary students’ mathematics education, and the
transition to higher education. Recently, my research has also focused on mathematics education
for younger students.
