Developing solutions to large-scale collective problems -- such as resilience to environmental challenges -- requires scientifically literate communities. However, the predominant conception of scientific literacy has focused on individuals, and there is not consensus as to what community level scientific literacy is or how to measure it. Thus, a 2016 National Academies of Sciences, Engineering, and Medicine report, “Science Literacy: Concepts, Contexts, and Consequences,” stated that community level scientific literacy is undertheorized and understudied. More specifically, the committee recommended that research is needed to understand both the i) contexts (e.g., a community’s physical and social setting) and ii) features of community organization (e.g., relationships within the community) that support community level science literacy and influence successful group action. This CAREER award responds to this nationally identified need by iteratively refining a model to conceptualize and measure community level scientific literacy. The model and metrics developed in this project may be applied to a wide range of topics (e.g., vaccination, pandemic response, genetically-modified foods, pollution control, and land-use decisions) to improve a community’s capacity to make scientifically-sound collective decisions. This CAREER award is funded by the Advancing Informal STEM Learning (AISL) and the EHR CORE Research (ECR) programs. It supports the AISL program goals to advance new approaches to, and evidence-based understanding of, the design and development of STEM learning in informal environments. It supports the ECR program goal to advance relevant research knowledge pertaining to STEM learning and learning environments.
The proposed research will conceptualize, operationalize, and measure community level scientific literacy. This project will use a comparative multiple case study research design. Three coastal communities, faced with the need to make scientifically-informed land-use decisions, will be studied sequentially. A convergent mixed methods design will be employed, in which qualitative and quantitative data collection and analyses are performed concurrently. To describe the i) context of each community case, this project will use qualitative research methods, including document analysis, observation, focus groups, and interviews. To measure the ii) features of community organization for each community case, social network analysis will be used. The results from this research will be disseminated throughout and at the culmination of the project through professional publications and conference presentations as well as with community stakeholders and the general public. The integrated education activities include a professional learning certificate for informal science education professionals and STEM graduate students. This certificate emphasizes high-quality community-engaged scholarship, placing students with partners such as museums, farmer’s markets, and libraries, to offer informal learning programs in their communities. This professional learning program will be tested as a model to provide training for STEM graduate students who would like to communicate their research to the public through outreach and extension activities.
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.

Access to STEM information is unequal, with rural and poor communities often receiving the fewest public education science and science literacy opportunities. Rural areas also face unique STEM teaching and technology integration challenges. In fact, LatinX communities in rural areas are less likely to have access to educational resources and language supports available to LatinX communities in urban centers. This project will help address these inequities by engaging rural librarians, bilingual science communicators, polar scientists, and a technical team to create a series of five bilingual virtual reality (VR) experiences to enhance STEM understanding and appreciation. Project researchers will create a new channel for disseminating polar science, working first with rural Latinx communities in Wisconsin to create a new network between rural communities and university researchers. Involving rural librarians in the co-design of instruction process will produce new ways for rural libraries to engage their local communities and their growing Latinx populations with polar science learning experiences. Each of the five VR experiences will focus on a different area of research, using the captivating Arctic and Antarctic environments as a central theme to convey science. VR is a particularly powerful and apt approach, making it possible to visit places that most cannot experience first-hand while also learning about the wide range of significant research taking place in polar regions. After design, prototyping and testing are finished, the VR experiences will be freely available for use nationally in both rural and urban settings. Public engagement with science creates a multitude of mutual benefits that result from a better-informed society. These benefits include greater trust and more reasoned scrutiny of science along with increased interest in STEM careers, many of which have higher earning potential. The project team will partner with 51 rural libraries which are valued community outlets valuable outlets to improve science literacy and public engagement with science. The effects of this project will be seen with thousands of community members who take part in the testing of prototype VR experiences during development and scaled engagement through ongoing library programs utilizing the final VR experiences for years to come.
This project will create new informal STEM learning assessment techniques through combining prior efforts in the areas of educational data mining for stealth assessment and viewpoint similarity metrics through monitoring gaze direction. Results of the project contribute to the field of educational data mining (EDM), focusing on adopting its methods for VR learning experiences. EDM is a process of using fine grained interaction data from a digital system to support educationally relevant conclusions and has been applied extensively to intelligent tutors and more recently, educational videogames. This project will continue building on existing approaches by expanding to include the unique affordances of VR learning media, specifically gaze. The project will focus on predicting user quitting as well as assessing key learning goals within each experience and triangulate these predictive models with user observations and post-experience surveys. The eventual application of this foundational research would address the problem in assessing a learner using measures external to the experience itself (i.e., surveys) and instead provide new methods that instrument learners using only data generated by their actions within the learning context. These techniques will provide a new means for evaluating informal learning in immersive technology settings without need for explicit tagging. The findings from this project will enable a greater understanding of the relationship between a user’s experience and their learning outcomes, which may prove integral in the creation of educational interventions using VR technology.
This Innovations in Development project is funded by the Advancing Informal STEM Learning (AISL) program, which seeks to (a) advance new approaches to and evidence-based understanding of the design and development of STEM learning in informal environments; (b) provide multiple pathways for broadening access to and engagement in STEM learning experiences; (c) advance innovative research on and assessment of STEM learning in informal environments; and (d) engage the public of all ages in learning STEM in informal environments. This project is also supported by the Office of Polar Programs.
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.
