My main research themes are:

 

  • mathematics learning and teaching in university and secondary school, including the secondary-tertiary transition and advanced mathematics studies; 
  • coming to grips with fundamental concepts and processes in mathematics (e.g., problem solving & posing, proving, defining, exemplifying) and investigating how digital resources and AI can be of help;
  • mathematicians' teaching practices, research, and the interrelations between them;
  • mathematical communication online and in hybrid spaces; 
  • theories of learning with a special interest in discursive and socio-cultural approaches.

 

I am currently seeking PhD applications with a strong mathematical background and keen interest in these or other themes. If you are interested in pursuing a PhD or a Research Assistant position, please fill out the Expression of Interest (EOI) Form on the left-hand side of this page.

Undergraduates' grasp of fundamental concepts and processes in mathematics

First-year university mathematics courses have gained a reputation of being intense, lecturer-centered, and difficult for many students. This project attempts to understand specific mathematical challenges that students experience, consider them from different theoretical angles, and offer new approaches to overcome them. 

 

Mathematics as an activity that develops throughout the curriculum

Some concepts appear multiple times in the students’ landscape of mathematics education when each time they are reconsidered in a new domain. For instance, angles in plane geometry and trigonometry, reciprocals of numbers and inverse functions, roots of real and complex numbers. A domanial shift is often accompanied by a redefinition, revision of familiar properties and an introduction of new ones. How do learners cope with new situations? How do they explain that something that was correct in one domain turns to be wrong in the new one? Are they even aware of the change? How does it feel when prior knowledge cannot be trusted?

 

Collaborative learning - not as straightforward as it may sound

​In mathematics education, students’ collaborations have gained a reputation as a ‘good’ learning practice. A more complex image emerges once collaborations are construed as an arena where cognitive, social, and affective matters intertwine in ways that can fuel and impede learning. This project delves into this complexity, aiming to understand the mechanisms of collaborative learning on a fine-grained level.

 

Mathematics learning with automated feedback

Contemporary AI-based technology is capable of not only assessing the correctness of students' answers but also providing meaningful feedback regarding changes that need to be implemented. This project explores how these technological affordances can be mobilized for students' learning.

 

Making sense of mathematical conventions

Conventions are fascinating creatures: some of them are reasonable and widely accepted, while others differ from one mathematical community to another. They are also rarely discussed in a classroom, which complicates the lives of many newcomers to mathematics. This project engages students and teachers with conventions and explores what "big" lessons about mathematics can be learned from them. 

 

Mathematical communication in online forums

​On the one hand, there is multiple evidence of a decline in students' interest in mathematics. On the other hand, there are infinitely many online forums with rich mathematical discussions. What is discussed there and how? How are these discussions different from the ones that we try to cultivate in our classrooms? How do students use these forums for coping with their classroom mathematics?

 

Mathematicians-researcher collaborations

​For too long, mathematics education research has treated mathematicians only as research subjects. This project reconsiders the relations between the community of mathematics education researchers and mathematicians, aiming to understand how the knowledge, skills, and resources that each community "brings to the table" can be leveraged to improve university mathematics education.
