Using RME to support PSTs’ meanings for quadratic relationships
Page: 440
Quadratic relationships are an important topic in algebra through calculus. In this report, we describe how a task designed using Realistic Mathematics Education (RME) principles supported students in developing meanings for quadratic relationships via their covariational reasoning. After describing the task design and sequence, we present student activity highlighting shifts in their meanings before, during, and after a six-week teaching experiment. We highlight the role of interactions amongst students, task, and the teacher in supporting such shifts. We conclude with a discussion and areas of future research.
