Early childhood is a critical time for developing foundational knowledge, skills, and interest in science, technology, engineering, and mathematics (STEM). For that reason, the Public Broadcasting Service (PBS) places a great priority on developing early childhood STEM content, especially through its television shows that are watched by over 60% of young children in the United States. Research suggests that adding in-the-moment interaction to television watching promotes learning and engagement. Toward this end, researchers from the University of California, Irvine and PBS KIDS have prototyped interactive versions of science shows that children view on internet-connected devices while they communicate with the main character powered by an AI conversational agent. Pilot studies show that when children watch these new interactive videos with the main character pausing periodically to ask probing questions about the learning goals of the episode and following up with appropriate responses, they are more engaged and learn more about science, with heightened benefits for children who speak languages other than English at home. Based on these early results, in this Innovations in Development project the research team will develop, test and produce publicly available conversational episodes for two PBS KIDS television shows, one focused on science and the other on computational thinking.
The project will iteratively study and develop six conversational videos with novel forms of support for children, including extended back-and-forth conversation that builds upon a child's responses, visual scaffolding that facilitates verbal communication, and bilingual language processing so that children can answer in English or Spanish. The conversational videos will be evaluated in both lab-based and home settings. The lab-based study will involve 600 children ages 3-7 in a predominantly low-income Latino community in Southern California, in which researchers compare children’s learning and engagement when watching the conversational videos with three other formats: (1) watching the non-interactive broadcast version of the video; (2) watching the video with pseudo-interaction, in which the main character asks questions and gives a generic response after a fixed amount of time but can’t understand what the child says; or (3) watching the broadcast version of the video with a human co-viewer who pauses the video and asks questions. The home-based study will involve 80 families assigned to watch either the non-interactive or interactive videos as many times as they want over a month at home. In both the lab-based and home studies, pre- and post-tests will be used to examine the impact of video watching on science and language learning, and log data will be used to assess children’s verbalization and engagement while watching. Following the home study, the six videos will be further refined and made available for free to the public through the PBS KIDS apps and website, which are visited by more than 13 million users a month. Beyond providing engaging science learning opportunities to children throughout the country, this study will yield important insights into the design, usability, feasibility, and effectiveness of incorporating conversational agents into children’s STEM-oriented video content, with implications for extending this innovation to other educational media such as e-books, games, apps, and toys.

As part of its overall strategy to enhance learning in informal environments, the Advancing Informal STEM Learning (AISL) program seeks to advance new approaches to, and evidence-based understanding of, the design and development of STEM learning in informal environments. This includes providing multiple pathways for broadening access to and engagement in STEM learning experiences, advancing innovative research on and assessment of STEM learning in informal environments, and developing understandings of deeper learning by participants. The project aims to understand ways to empower Latinx families (adult caregivers) to feel confident in their ability to support their middle school-aged girls in science and engineering activities. The project involves seven weeks of family programming around rockets or urban farming, as well as separate conversation groups for adult family members and girls. The project is relevant for several reasons: females and Latinx individuals are both underrepresented in science, technology, engineering, and math (STEM) coursework and careers; girls tend to lose interest in STEM by middle school age; and adult family members may have an impact on their children's attitudes and interests. The project partners with school districts and nonprofit organizations in Arizona and California.
This multidisciplinary project's priority is broadening participation, with a focus on increasing Latina girls' science and engineering interests through Family Project-Based Learning Activities, Conversation Groups, and a cultivated Community of Learners. It is based on the frameworks of Social Cognitive Career Theory and Community Cultural Wealth. The project aims to empower families (adult caregivers) to feel confident in their ability to support their daughters in science and engineering activities, which is often low especially among Latinx parents. The project will develop and evaluate two out-of-school enrichment methods for aiding families in encouraging and supporting their daughters in science: Family Problem-Based Learning Activities, which focus on rockets and urban farming, and Conversation Groups, which provide information and discussion for separate groups of parents and girls. A series of pilot studies will be conducted with 80 families to iteratively evaluate and improve the materials and procedure prior to the main study with 180 families, featuring a factorial design with a control group.
The materials developed and research findings may inform similar projects, especially those for students from culturally and linguistically diverse backgrounds and projects seeking to enhance the role of families in learning. The hypothesis guiding the project is that the greatest gains will be produced with the synergistic combination of enrichment methods. Another component that can potentially have broad impact is working to create environments where Community Cultural Wealth is recognized and enhanced through interactions of different families, creating Communities of Learners. This can inform projects that recognize the importance of community and/or that seek to use culture as an asset. The proposed study will engage three geographically distributed universities and several community partners. It will also provide university students and community leaders opportunities for work on instructional design, implementation, and research. The team will disseminate their findings and methods through multiple avenues to reach researchers, parents, leaders, curators, and educators in informal and K-12 settings.

This project responds to the Faculty Early Career Development Program (CAREER) solicitation (NSF 17-537) and is sponsored by the Advancing Informal STEM Learning program at the National Science Foundation. CAREER: Talking Science: Early STEM Identity Formation Through Everyday Science Talk (Talking Science) addresses the critical issue of the development of children's identification with science, technology, engineering and mathematics (STEM) fields and the limited knowledge about the development of STEM identity through conversations, particularly among very young children from underserved and underrepresented populations. Talking Science is based on the premise that individuals who develop STEM interests and identify with STEM at a young age tend to participate in STEM fields more so than individuals who develop these later in life. This study investigates how STEM-related conversations outside of school with friends and family during formative years (i.e., 7 - 12 years old) shape youths’ STEM identity later in life and their engagement in STEM. The goals of Talking Science are (1) To develop an understanding of the features and context of conversations held between children and their caregivers/teachers that support STEM identity development in both majority and Hispanic/Latine populations; and (2) To translate the research outcomes into informal STEM learning practices that positively contribute to young people's perceptions of STEM fields in their future.
To achieve its goals, this work addresses the following research questions: (1) What is the content, context, and structure of STEM-related conversations with friends and family that youth ages 7 - 12 participate in?; (2) How do the features of conversation (i.e., content, context, structure) relate to the development of youth's STEM interests, sense of recognition as STEM people, and self-identification with STEM?; (3) How do the cultural values and science talk experiences of Hispanic/Latine youth shape conversation features related to youth's STEM interests, sense of recognition as STEM people, and self-identification with STEM?; and (4) Does professional development for practitioners that focuses on encouraging youth to engage in STEM-related conversations with friends and family positively contribute to youth's STEM interest, sense of recognition, and self-identification with STEM? To address these questions, the study adopts a qualitative research approach that applies phenomenological strategies in research design, data collection, and analysis to allow for exploration of the meaning of lived experiences in social and cultural contexts. Participants include elementary-age youths (ages 7 - 12) and caregivers from socially, culturally, linguistically, and economically diverse backgrounds. To inform the development of interview protocols in terms of the kinds of childhood talk that leave a long-term impact on students, including the kinds of talk experiences remembered by students who choose or persist towards a STEM career in college, the project also recruits college students pursuing STEM degrees as participants. Data gathering and interpretation strategies include surveys and interviews. The outcomes of this research will constitute a theoretical framework and models that guide the development of both professionals and programmatic activities at informal learning institutions, particularly around scaffolding participation in STEM through family science talk.
