Research interests

The area of focus in my PhD project involves ICT in mathematics education, mathematical competencies and design research. During my master’s thesis, I have engaged in the areas of preservice teacher education, mathematical knowledge for teaching, mathematics teacher competencies and networking of theories. Additionally, in PISA related work, I have focused on mathematical literacy and curriculum studies.
