Researching One's Own Practice: Reflections on the Teaching of Linear Algebra Using Multimodal Narratives

Abstract

This chapter aims to link the known research results on the teaching and learning of linear algebra to research on teaching practices. The same person, as a teacher and as a researcher, plans and implements a teaching sequence, constructs multimodal narratives (MNs) for some classes, and reflects on his own practice, based on the emerging categories from content analysis of the MNs. Regarding the methodology and focusing on the role of MNs in this research, it is worth highlighting the value attributed to MNs because they function as an instrument that embodies the practices of the teacher and aid him in reflecting on his own practice.
