This case study presents interviews with district and campus leaders along with valuable insights from 4th grade pilot teachers. Significant shifts in assessment tools and instructional materials, and the development of strong data literacy skills and improved data practices are evident in the comments from district leaders to students. In addition, the section "Blended Classroom Deep Dive - 4th grade" describes how one teacher pivoted from traditional to blended instruction. The teacher reflects on new classroom structures, student onboarding and classroom culture shifts, and each instructional component. Short snapshots of two 4th grade ELA classrooms are also informative.
