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.

Cyberchase: Mobile Adventures in STEM is designed to advance the STEM learning of children ages 6-8 and engage low-income families in informal STEM interactions. Based on a successful NSF-funded pilot, the project combines the appeal of the PBS KIDS series Cyberchase and the potential of mobile texting to deliver informal learning. WNET and Education Development Center will produce: three Cyberchase videos that blend math and environmental content; a bilingual family engagement campaign in 15 communities across the U.S. that combines this media with weekly text-based engagement; and research into use and impact of the model among low-income Latinx families. Mobile Adventures addresses the need to better engage underserved families in informal science practices that are foundational for future STEM learning. While the materials target low-income communities broadly, research will focus on low-income Latinx families with children ages 6-8, an age group overlooked in previous research on educational uses of texting. A needs assessment and formative testing will ensure that the project design meets the needs and interests of diverse Latinx and other families.
The goal of Mobile Adventures is to build knowledge about how innovative, culturally responsive tools can help Latinx and low-income families engage in fun STEM learning at home. A three-tiered research study will address the question: how and to what extent does a mobile text-and-media approach to delivering informal STEM learning materials foster joint media engagement between children and parents, building new repertoires for learning together? The study will combine analysis of observation in homes and community settings, backend data, and pre/post surveys. Research will deepen understanding of effective family engagement models that make media a central component, the potential of text messaging as a stimulus to parent/child STEM learning, and maximal design of media and community engagement to serve low-income Latinx families. Findings will be disseminated through national conferences and journals. The Cyberchase videos, distributed free on broadcast and digital platforms, will build the STEM literacy of millions of diverse children, while the family engagement campaign will involve a projected 3,750 families in 15 locations. Evaluation will assess how well the project has met its goals.

Increasing greater diversity, equity, and inclusion in science not only presents a social justice goal, but is also vital to the financial and social success of the nation. The stereotype of the older white male scientist has obscured the contributions of women and people of color. This project seeks to remedy these perceptions which are barriers to entry into STEM fields. The project will create a large-scale hub for STEM themed video content on YouTube and other social media platforms, featuring 100+ original STEM videos produced by PBS partners. This hub and accompanying research seeks to identify the characteristics of online STEM content that attract (or fail to attract) underrepresented groups, specifically Black and Hispanic communities as well as women of all races. The objectives of this project are to 1) provide a unified online science-themed hub, PBS Terra, on YouTube and other platforms for hosting, sharing, and distributing digital STEM series from diverse producers from across the PBS system; 2) conduct surveys and focus groups to examine and understand the needs and expectations of women, Black and Hispanic communities and their consumption of STEM video content online and 3) test hypotheses about the communicative strategies of STEM videos that feature Black and Hispanic female scientists. Project collaborators include PBS, researchers at the University of Utah and the University of Georgia, and consultants and advisors with expertise in broadening participation and inclusion in STEM.
Little is known about how or why adult Americans seek science content on YouTube, especially the motivations of adults from underrepresented minorities and females. The key research questions in this project are: 1) Why do Black and Hispanic audiences and women of all races seek science video content online? 2) How does showing Black and Hispanic female scientists in science video content on YouTube impact viewers’ identification with and sense of belonging in STEM? 3) How does the use of humor by Black and Hispanic scientists in YouTube science content affect viewers’ perceptions of the communicator and their engagement with STEM content? 4) How does the appearance and manner of dress of Black and Hispanic scientists in YouTube science content affect viewers’ perceptions in the aforementioned areas? A nationally representative baseline survey will be conducted. A probability sample of 2000 respondents will be obtained including oversampling of Black and Hispanic audiences. To complement findings from the survey, focus groups will be conducted in eight different regions of the country to learn why these targeted audiences do or do not seek science content on YouTube and what motivates them to share the content with their social media network. In addition, an experiment embedded in an online survey will test the hypothesis that greater on-screen representation of women and scientists of color will broaden existing perceptions about scientists. The experiment will consist of a 3 (scientist’s race: Black/Hispanic/White) × 2 (science issue: controversial/non-controversial) × 2 (style: casual/professional) between-subjects design. Survey participants will be randomly assigned to the experimental conditions. These factors (science issue and host appearance) can be altered by content producers to better reach and engage the targeted audiences. The project not only investigates theoretical questions at the intersection of STEM stereotypes and race, but findings related to these experimental conditions will offer practical insight into strategies that can be used by science communication practitioners.

Mentoring is a widely accepted strategy for helping youth see how their interests and abilities fit with education and career pathways; however, more research is needed to better understand how different approaches to mentoring impact youth participants. Near-peer mentoring can be a particularly impactful approach, particularly when youth can identify with their mentors. This project investigates three approaches to near-peer mentoring of high-school-aged Hispanic youth by Hispanic undergraduate mathematics majors. Mentoring approaches include undergraduates' visits to high school classrooms, mathematics social media, and a summer math research camp. These three components of the intervention are aimed at facilitating enjoyment of advanced mathematics through dynamic, experiential learning and helping high school aged youth to align themselves with other doers of mathematics on the academic stage just beyond them, i.e., college.
Using a Design-Based Research approach that involves mixed methods, the research investigates how the three different near-peer mentoring approaches impact youth participants' attitudes and interests related to studying mathematics and pursuing a career in mathematics, the youth's sense of whether they themselves are doers of mathematics, and the youth's academic progress in mathematics. The project design and research study focus on the development of mathematical identity, where a mathematics identity encompasses a person's self-understanding of himself or herself in the context of doing mathematics, and is grounded in Anderson (2007)'s four faces of identity: Engage, Imagine, Achieve, and Nature. The study findings have the potential to uncover associations between informal interactions involving the near-peer groups of high school aged youth and undergraduates seen to impact attitudes, achievement, course selection choices, and identities relative to mathematics. It also responds to an important gap in current understandings regarding effective communication of mathematics through social media outlets, and results will describe the value of in-person mathematical interactions as well as online interactions through social media. The study will result in a model for using informal near-peer mentoring and social media applications for attracting young people to study and pursue careers in STEM. This project will also result in a body of scripted MathShow presentations and materials and Math Social Media content that will be publicly available to audiences internationally via YouTube and Instagram.
This Research in Service to Practice project is funded by the Advancing Informal STEM Learning (AISL) program, which 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.
This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
