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.

Informal STEM education spaces like museums can intentionally serve surrounding communities and support sustainable and accessible engagement. Building from this base, the project takes a stance that the intersection of the museum, home/family life and the youth’s internal practices and disciplinary sense of self are rooted in history and culture. Thus, this CAREER work builds on the following principles: Black families and youth have rightful presence in STEM and in STEM learning environments; Black families are valuable learning partners; and Black youths need counterspaces to explore STEM as one mechanism for creating future disciplinary agency. In partnership with the Henry Ford Museum and the Detroit-Area Pre-College Engineering Program, the project seeks to (a) expand the field's understanding of how Black youth engineer and innovate; (b) investigate the influence of a culturally relevant curriculum on their engineering practices and identity, knowledge, and confidence; and (c) describe the ways Black families and museums support youth in engineering learning experiences. The work will center on the 20-hour “Innovate” curriculum which was designed by the museum to bridge design, innovation, and creation practices with the artifacts of innovators throughout time. The project comprises six weekend “Innovate” sessions and an at-home innovation experience plus participation in an annual Invention Convention. By focusing on these aims, this research responds to the goals of the Advancing Informal STEM Learning (AISL) program, which seeks to advance evidence-based understanding of the design and development of STEM learning opportunities for the public in informal environments. This includes providing multiple pathways for broadening engagement in STEM learning experiences and advancing innovative research on STEM learning in informal environments.
The main research questions of this multiphase CAREER award are: (1) What practices do Black youths and families engage in as they address engineering, design, and innovation challenges? (2) In what ways does a culturally relevant museum-based innovation program influence the design and innovation practices and assessment performance of Black youths and families as they engage in engineering, design, and innovation across learning settings? (3) How does teaching innovation, design, and engineering through historical re-telling and reconstruction influence a youth’s perception of their own identities, abilities, and practices? and (4) How do Black families engage with informal STEM learning settings and what resources best support their engineering, design, and innovation exploration? Youth in sixth grade are the focus of the research. The work is guided by ecological systems, sociocultural learning, culturally relevant pedagogy, and community cultural wealth theories. During phase one, the focus will be to refine the curriculum and logistics of the study implementation. The investigator will enhance the curriculum to include narratives of Black innovators and engineers. Fifteen families will be recruited to participate in the program enhancement pilot and initial research cycle for phase two. In phase three another cohort of families will be recruited to participate. Survey research, narrative inquiry and digital ethnography will comprise the approaches to explore the research questions. The evaluation has a two-pronged focus: to assess (1) how well the enhanced Innovate curriculum and museum/home learning experience supports Black families’ participation and (2) how well the separate phases of the study connect and operate together to meet the research aims. The study’s findings can help families and informal practitioners leverage evidence-based approaches to support Black youth in making connections between history and out-of-school contexts to model and develop their innovative engineering practices. Additionally, this work has implications for Black undergraduate students who will develop skills through their mentorship and researcher roles, studying cultural practices and learning experiences. The research study and findings can inform the design of future museum/home learning programs and research opportunities for Black learners in informal learning spaces.

Recent studies have advocated for a shift toward educational practices that involve learners in actively contributing to science, technology, engineering, and mathematics (STEM) as a shared and public endeavor, rather than limiting their involvement to the construction of previously established knowledge. Prioritizing learners’ agency in deciding what is worth knowing and how learning takes place may create more equitable and inclusive learning experiences by centering the knowledge, cultural practices, and social interactions that motivate learning for people across ages, genders, and backgrounds. In informal learning environments, families’ social interactions are critical avenues for STEM learning, and science centers and museums have developed strategies for prompting families’ sustained engagement and conversation at STEM exhibits. However, exhibits often guide visitors’ exploration toward predetermined insights, constraining the ways that families can interact with STEM content, and neglecting opportunities to tap into their prior knowledge. Practices in the maker movement that emphasize skill-building and creative expression, and participatory practices in museums that invite visitors to contribute to exhibits in consequential ways both have the potential to reframe STEM learning as an ongoing, social process that welcomes diverse perspectives. Yet little is known about how these practices can be scaled, and how families themselves respond to these efforts, particularly for the diverse family audiences that science centers and museums aim to serve. Further, although gender and ethnicity both affect learning in informal settings, studies often separate participants along a single dimension, obscuring important nuances in families’ experiences. By addressing these outstanding questions, this research responds to the goals of the Advancing Informal STEM Learning (AISL) program, which seeks to advance evidence-based understanding of the design and development of STEM learning opportunities for the public in informal environments. This includes providing multiple pathways for broadening engagement in STEM learning experiences and advancing innovative research on STEM learning in informal environments.
Research will address (1) how families perceive and act on their collective epistemic agency while exploring STEM exhibits (i.e., how they work together to negotiate and pursue their own learning goals); (2) whether and how families’ expressions of agency are influenced by gender and ethnicity; and (3) what exhibit design features support expressions of agency for the broadest possible audience. Research studies will use interviews and observational case studies at a range of exhibits with distinct affordances to examine families’ epistemic agency as a shared, social practice. Cultural historical activity theory and intersectional approaches will guide qualitative analyses of families’ activities as systems that are mediated by the physical environment and social setting. Education activities will involve an ongoing collaboration between researchers, exhibit designers, educators, and facilitators (high-school and college-level floor staff), using a Change Laboratory model. The group will use emerging findings from the research to create a reflection tool to guide the development of more inclusive learning experiences at STEM exhibits, and a set of design principles for supporting families’ expressions of agency. A longitudinal ethnographic study will document the development of inclusive exhibit design practices throughout the project as well as how the Change Lab participants develop their sociocultural perspectives on learning and exhibit design over time. Analyzing these shifts in practice within the Change Lab will provide a deeper understanding of what works and what is difficult or does not occur when working toward infrastructure change in museums. By considering how multiple aspects of families’ identities shape their learning experiences, this work will generate evidence-based recommendations to help science centers and museums develop more inclusive practices that foster a sense of ownership over the learning process for the broadest possible audience of families.
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.
