A Blended Teaching Sequence for Introducing Eigentheory in a Large University Class

We present the design and implementation of a teaching sequence on eigentheory that aims at encouraging at facilitating students' active participation in a class attended by a high number of students. We describe how the use of the online noticing board Padlet facilitates the implementation of activities in small groups during lectures. These activities are designed based on the results of a pilot study aimed at assessing students' understanding of eigentheory notions. We analyze various types of data collected during and after the implementation, showing a positive response from both the course teacher and the students to this teaching and learning methodology.
