"This book addresses the renewed focus in mathematics education for students to embrace the role of a mathematician and experience mathematics in authentic situations. This chapter also highlights attributes of the ideal mathematics classroom and the relationship to the PBL Mathematics classroom. A discussion of the intersection between equity-based mathematics teaching practices and PBL equity levers is highlighted. This book discusses the characteristics of a problem-solving task, a performance task, and a project as well as the ways these three teaching practices leverage equity-based mathematics teaching practices. What does it mean to be a mathematician? Who is a mathematician? These questions continue to be asked, challenged, and re-invented in our mathematics community"-- Provided by publisher.
