We examine different roles that caregivers took on during the implementation of the prompts to organize families’ engineering learning activities. Narrative accounts and transcriptions were analyzed to investigate the different roles that caregivers took. Three roles emerged: caregivers as monitor; caregivers as mentor; caregivers as partner. We further coded families’ talks to investigate how three different caregivers’ roles influenced families’ engineering practices and caregiver-child talk types. Preliminary findings illustrate how three caregivers’ roles enabled and constrained different types of engineering practices and caregiver-child talk types. Findings contribute to future considerations in designing discussion prompts for at-home engineering kits. Country unknown/Code not availableOSTI-MSA
