Families commonly document their outings by capturing their experiences through digital photographs and videos. However, little is known about the ways in which families engage their personal mobile devices to document educational family outings and how they subsequently talk about the digital artifacts that captured their informal learning experiences. This paper presents new evidence on family digital artifact creation during an informal science institution (ISI) visit, the expected and actual uses of their digital artifacts after the visit, and family conversations reminiscing about the ISI visit with the digital artifacts. Using a concurrent triangulation mixed-methods design, data on family digital artifact creation during an aquarium visit (N = 204) and digital artifact use after the visit (n = 67) were collected using parent surveys. Audio-recorded parent-child conversations with a subset of families (n = 25) document whether and how families use their digital artifacts to reminisce about the aquarium visit. Quantitative findings detail family digital technology practices during informal learning experiences, and qualitative findings suggest evidence of informal science learning in the everyday interactions of the families who elected to continue the study. The study indicates that family storytelling and digital technology practices may help to bridge informal science learning from ISI to home and frames family non-participation within an anti-deficit perspective.
