Bjarnheiður Kristinsdóttir (She/Her)

I work both at the School of Engineering and Natural Science (Faculty of Physical Sciences) and School of Education (Faculty of Subject Teacher Education) and divide my time between two offices in Tæknigarður (315) and Stakkahlíð (K-203). My research focuses on the collaboration between unviersity and upper secondary school mathematics teachers, the design of rich mathematical tasks for upper secondary school students, the use of digital technology (e.g., GeoGebra, Desmos, and AR) to support students' learning of mathematics, teacher noticing, pre-service and in-service teachers' implementation of the Building Thinking Classroom practices, and the design of mathematics teacher professional development courses. I have been an active participant in the Nordic-Baltic GeoGebra Network since 2012, collaborated with the GeoGebra Institute in Linz since 2016, and regularly participate in conferences such as CERME, ICTMT, and MEDA. In 2020-23, I participated in the EU funded project Colette on behalf of the Johannes Kepler University in Linz, designing tasks intended to enhance and support students' computational thinking.
