S3 Lab Research

In Progress

S3 Lab is conducting over a dozen projects in nearly 400 schools and universities involving more than 135,000 students. All of these projects involve mobilizing and empowering social systems to support student achievement. This work is at varying stages of completion, so please keep checking and follow @Todd_Rogers_ on twitter for updates.

A sampling of projects we are working on:

  • Reducing absences among at-risk K-12 students by providing parents with regular messages targeting specific attendance beliefs.
  • Turning friends and family in college students’ social networks into “Study Supporters” by regularly empowering them to get more involved with updates about the students’ courses, upcoming deadlines, and campus resources.
  • “Inviting the village” that surrounds K-12 students (e.g. grandparents, mentors, coaches, family friends) by empowering these supporters with actionable information they can use to encourage and support students (e.g., report cards, class schedules, attendance reports, etc.).
