This study explores the relationship between an Affective Instructional Design (AID), children’s attitudes toward math, and math learning. Participants included 15 kindergarten children at a university K-12 laboratory school located in East Tennessee. This quasi-experimental study employed a pretest-intervention (AID)-posttest design. Data, including pretest/posttest attitude surveys, and baseline and intervention non-participant video observations of math learning and math attitudes, during 13 math lessons were coded and analyzed. As hypothesized, a significant positive correlation (r = 0.936, p = 0.000) was found between attitude and math learning. Additionally significant differences were found between the baseline (pre-intervention) mean score and the final intervention lesson for both math attitude, t(14) = -12.39, p = 0.008, and math learning, t(14) = -8.40, p = 0.002.These findings suggest AID could be one route to supporting educators in establishing quality learning environments that promote positive attitudes and meaningful learning in mathematics.
