Abstract

Digital tools and technology-based activities offer new and promising opportunities for students to actively explore mathematical concepts and ideas in ways supported by current reforms and visions of mathematics instruction. This report provides an in-depth look at the implementation of SunBay Digital Mathematics (SunBay Math) during the second year of an i3 validation project, in two large Florida districts. SunBay Math is a set of middle-school curriculum replacement units centered on the use of technology-based, dynamically linked representations to learn core mathematical concepts. We focus specifically on patterns and relationships between instructional practices and instructional quality in 26 videotaped lesson enactments that were purposefully collected to represent variation in implementation.
