Associations between parents' autonomy supportive management language and children's science, technology, engineering, and mathematics talk during and after tinkering at home.

We conducted a time series analysis of parents' autonomy supportive and directive language and parents' and children's STEM (science, technology, engineering, and mathematics) talk during and after a problem-solving activity (i.e., tinkering). Parent and child dyads (N = 61 children; M = 8.10 years; 31 boys; 54% White) were observed at home via Zoom. After tinkering, a researcher elicited children's reflections, and approximately 2 weeks later dyads reminisced together about the experience. During tinkering, the more autonomy supportive STEM talk parents used in 1 min, the more children talked about STEM in the next minute. During reminiscing, parents' autonomy support was also associated with children's STEM talk. Results suggest the importance of considering how both the content and style of parents' talk can support children's STEM engagement.
