Ariadne Nelson is a postdoctoral researcher working with Dr. Susan Levine. Ari has a Ph.D. in Applied Developmental and Educational Psychology from Boston College and a master’s in Infant Mental Health from Mills College. Ari is primarily interested in understanding how young children develop knowledge through everyday interactions with caregivers. She uses qualitative and quantitative methods to study how parents and preschoolers engage in math conversations during different types of activities. For her work with the Development and Research in Early Math Education (DREME) Network, she has developed and evaluated activities and resources for promoting enriching math engagement in family and classroom contexts. For a different project, Ari conducted an RCT to evaluate the utility of a tutoring model in which undergraduate students deliver curriculum-based math tutoring to elementary school students. This project involved developing and implementing an afterschool math tutoring program that paired UChicago undergraduate tutors with students at neighborhood schools. Prior to her time at UChicago, Ari interned at the Museum of Science, Boston, worked as an early childhood assessor for SRI International and Abt Associates, and worked for Resource Development Associates, a consulting firm specializing in evaluation, strategic planning, and grant writing for government agencies and nonprofits.
