  2. Thank you • Justin Reich • Heather Sternshein • Jeff Emanuel • Greg Nagy • Ichiro Kawachi • Monica Wang • Dimitar Sasselov • Albert Wang • Dan Levy

  3. Overview • Two projects • Study Supporter (twice+) • Commitment Device • Wrap up

  4. “Study Supporter” Experiment How do we leverage social support to help students succeed? Experiment design: • Name supporter • Assigned to treatment or control • Reach out key moments • Measure persistence, achievement • Iterate: • Which students benefit most? • What kind of supporter is best? • How best to communicate with supporter? • Etc.

  5. HeroesX, CB22x, Spring 2013 • Professor Nagy agreed, pitched several professors • Recruitment: • Emails, icon on homepage • Sample size • N=285 (0.7% of enrollees) • Treatment • Administered via email only • Content reflects course material • E.g., “Ask Todd, why did Oedipus poke his own eyes out?”

  6. Health and SocietyX, PH201X, Fall 2014 • Professor Ichiro agreed, pitched several professors • Recruitment: • Built into pre-course survey • Very weak ask in pre-course survey • Sample size • N=661 (1.8% of enrollees) • 2.6X higher yield than CB22x • Treatment • Collected and used email (and SMS when provided) • Specifically asked for Non-coresident • 20% still named coresitant, though • Content reflects course material

  7. Health and Society X Non cohabitants=543; cohabitants=118 Interaction p=.04; non-cohabs only p=.08

  8. Non cohabitants=543; cohabitants=118 Interaction p=.08

  9. Tangible ThingsUSW30x, Summer 2014 • New Study Supporterplanned • SMS • Recruitment • Stronger recruitment • Larger N, hopefully • A priori hypotheses • Pre-registered hypotheses and analysis plan • Post-experiment mechanism survey of students/supporters

  10. Commitment Devices(With Albert Wang, HILT Fellow) Prof. Sasselov agreed • SPU30x: Super-Earths And Life • Launches May 15

  11. 3 Thoughts on Collaboration with Hx • “Costless” experiments require too many people to say “Yes” • Marketplace for research projects requires guerilla marketing (fine for me, but inefficient) • Data merging has required lots of work
