Fraction Understanding in 2nd & 5th Graders

The Educational Neuroscience Lab and Mathematics Education Learning & Development Lab are working with the Waisman Center to investigate the development of fraction knowledge in children. Knowledge of fractions and mathematical competence are important determinants of life chances in modern society. Despite the importance of fraction knowledge, children and adults often encounter considerable difficulties understanding fractions. We are currently recruiting typically developing 2nd and 5th graders enrolled in Madison area public schools to participate in our longitudinal study.

Participation will involve completing 2-4 sessions with us per year for four years. Sessions will include computer games about math, standardized assessments, surveys, and brain imaging. To qualify for the brain imaging portion, participants must pass the fMRI screening. Participants may not participate in the brain imaging portion of the study if they have any metal in their body or experience claustrophobia.

For every behavioral session completed, participants will receive $10.
For every brain imaging session completed, participants will receive $50.
Children under the age of 12 will also receive a toy after each session.
