Feasibility of Behavior Change Techniques to Increase Parent Involvement in STEM ?with Young Children Experiencing Poverty
Broadening participation in early, informal STEM is important for families experiencing poverty. We explored the feasibility of the Teaching Together STEM preschool program for increasing home-based parent involvement and reducing barriers to informal STEM learning with 181 families at schools where 92% of students received free/reduced lunch. The core treatment included family engagement events and text messages; STEM events were delivered at school sites by museum-based informal science educators. We randomly assigned schools to business-as-usual or one of three additive treatment groups to evaluate adult behavior change techniques of adding materials and parent rewards to the core treatment. The primary outcome was parent involvement in STEM. There were no significant impacts of any treatment on home-based parent involvement in STEM; however, the groups that included take-home activity kits along with family education events/resources were the most promising way to get focal parents involved in doing science and math with their young child. Interestingly, the most intensive treatment group that added parent monetary rewards produced short-term improvements in parent involvement that faded at a later follow-up timepoint. We discuss the relative effects of different behavior change techniques and uptake of components, as this has implications for family engagement programs that aim to ensure equity when many parents have competing demands on their time.
