Using Design Research to Develop an Activity to Introduce Limit of a Sequence: “Getting Back to Sesame Street”
Page: 1-270
This report is based on work completed within an ongoing project to develop a calculus course which serves as the foundation for the mathematical education of STEM-focused elementary teachers at a large southeastern university. In the process of designing and implementing the course materials, several research-based activities have been developed, tested and refined. In this paper we discuss how we used a design research approach to create and implement an activity that introduces the concept of limit of a sequence using popular characters from Sesame Street. We report on the first two design cycles in the ongoing design of this activity and discuss the modifications made in both the broad learning goals and the activity drafts.
