Summary of thesis
Over the last decade, digital fabrication (DF) technologies, such as 3D printers, laser- and vinyl cutters, have become affordable for consumers, and so-called Maker Spaces and fabrication labs where people meet and make things using DF technologies are becoming more common.
In this project, I inquire into the opportunities that DF could bring to mathematics teacher education to utilize the technologies to make manipulatives that can be successfully integrated into teachers’ practice.
Since few teachers have experience with using DF, I inquire into how DF can be introduced to mathematics teachers. Furthermore, I explore how teachers’ experiences may impact their practice. My overarching research questions are:
- How can DF be introduced to mathematics teachers for making manipulatives?
- What are teachers’ reflections on their ability to change their practice concerning manipulatives after being introduced to DF for making mathematical manipulatives?
I employed Community of Inquiry as an overarching theory and developmental research as methodology to design and implement two workshop series.
My thesis contributes to mathematics teacher education by expanding the theoretical, methodological, and practical knowledge about teachers’ use of DF for making mathematical manipulatives.
