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.
This Innovations in Development project is funded by the Advancing Informal STEM Learning (AISL) program.

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.

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.
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.

Wireless radio communications, such as Wi-Fi, transmit public and private data from one device to another, including cell phones, computers, medical equipment, satellites, space rockets, and air traffic control. Despite their critical role and prevalence, many people are unfamiliar with radio waves, how they are generated and interact with their surroundings, and why they are the basis of modern communication and navigation. This topic is not only increasingly relevant to the technological lives of today’s youth and public, it is critical to the National Science Foundation’s Industries of the Future activities, particularly in advancing wireless education and workforce development. In this project, STEM professionals from academia, industry and informal education will join forces to design, evaluate, and launch digital apps, a craft-based toolkit, activity guides, and mobile online professional learning, all of which will be easily accessed and flexibly adapted by informal educators to engage youth and the public about radio frequency communications. Experiences will include embodied activities, such as physically linking arms to create and explore longitudinal and transverse waves; mobile experiences, such as augmented reality explorations of Wi-Fi signals or collaborative signal jamming simulations; and technological exploration, such as sending and receiving encrypted messages.
BSCS Science Learning, Georgia Tech, and the Children’s Creativity Museum (CCM) with National Informal STEM Education Network (NISE Net) museum partners will create pedagogical activity designs, digital apps, and a mobile online professional learning platform. The project features a rigorous and multipronged research and development approach that builds on prior learning sciences studies to advance a learning design framework for nimble, mobile informal education, while incorporating the best aspects of hands-on learning. This project is testing two related hypotheses: 1) a mobile strategy can be effective for supporting just-in-time informal education of a highly technical, scientific topic, and 2) a mobile suite of resources, including professional learning, can be used to teach informal educators, youth, and the general public about radio frequency communications. Data sources include pre- and post- surveys, interviews, and focus groups with a wide array of educators and learners.
A front-end study will identify gaps in public understanding and perceptions specific to radio frequency communications, and serve as a baseline for components of the summative research. Iterative formative evaluation will incorporate participatory co-design processes with youth and informal educators. These processes will support materials that are age-appropriate and culturally responsive to not only youth, with an emphasis on Latinx youth, but also informal educators and the broader public. Summative evaluation will examine the impact of the mobile suite of resources on informal educators’ learning, facilitation confidence and intentions to continue to incorporate the project resources into their practice. The preparation of educators in supporting public understanding of highly technological STEM topics can be an effective way for supporting just-in-time public engagement and interests in related careers. Data from youth and museum visitors will examine changes to interest, science self-efficacy, content knowledge, and STEM-related career interest. If successful, this design approach may influence how mobile resources are designed and organized effectively to impact future informal education on similarly important technology-rich topics. All materials will be released under Creative Commons licenses allowing for widespread sharing and remixing; research and design findings will be published in academic, industry, and practitioner journals.
This project is co-funded by two NSF programs: The Advancing Informal STEM Learning program, which seeks to advance new approaches to, and evidence-based understanding of, the design and development of STEM learning in informal environments.

On October 1, 2015, Oregon Public Broadcasting (OPB) was awarded a 3‑year grant of 2.7 million dollars from the National Science Foundation (NSF) to fund the project Hacking Your Mind (award number 1515520). A major public and social media project, Hacking Your Mind (HYM) planned to engage Americans with the new discoveries being made in the social, behavioral, and economic sciences and the remarkable insights these discoveries offer into how individuals make numerous daily decisions and judgments, as well as the broader impact of this highly personal phenomenon on nearly every aspect of
From a strategic communication perspective, for any communication to be effective, it must be audience-centered, with content and delivery channels that are relevant to its intended target. When trying to reach culturally specific communities or other groups that are not otherwise connected with science research, it is crucial to partner with community members to co-create content through media that is appealing and culturally competent. This commentary considers some examples including storytelling through ‘fotonovelas’ and radio stories, community drama and serious games.
For at-risk children who cannot attend preschool, accessing science activities depends almost entirely on parents—but many parents have limited skills for supporting such learning. PBS station WGBH has recently launched a series of free family apps based on the Emmy Award-winning preschool science series, PEEP and the Big Wide World. The apps were developed to be used jointly by parent and child for a shared learning experience. Available on Google Play and the App Store in both Spanish and English, PEEP Family Science apps cover the topics of shadows, sound, color, and ramps, respectively.
To engage parents and young children in exploring science together, media producers from WGBH (Boston’s public media station) and researchers from Education Development Center (EDC) collaborated with two home-visiting organizations—Home Instruction for Parents of Preschool Youngsters (HIPPY USA) and AVANCE—to design and test PEEP Family Science, an app-based intervention with science-focused digital media resources and associated supports for diverse, low-income families. Both organizations target families whose children do not attend preschool. These home visiting organizations play a unique
This RAPID was submitted in response to the NSF Dear Colleague letter related to the COVID-19 pandemic. This award is made by the AISL program in the Division of Research on Learning, using funds from the Coronavirus Aid, Relief, and Economic Security (CARES) Act. COVID-19 presents a national threat to the health of children and families, presenting serious implications for the mental and physical health of children. Child development scientists have already warned of increasing stress levels among the U.S. child population, especially those in low-income families of color. In addition, Latino children are disproportionately impoverished, and benefit from culturally relevant information. Parents and caregivers need to be armed with effective science-based strategies to improve child prospects during this global crisis. Harnessing well-established partnership (including with local TV news partners and parent-serving organizations) strengthens the potential for broad impacts on the health and well-being of children and families during the COVID-19 pandemic. As the pandemic persists, widely disseminating accurate research-based strategies to support parents and families, with a focus on low-income Latino parents, is crucial to meeting the needs of the nation's most vulnerable during this global crisis. The award addresses this urgent need by producing research-based news videos on child development for distribution on broadcast television stations that reach low income Latino parents. The videos will communicate research-based recommendations regarding COVID-19 in ways that are relatable to Latino parents and lead to positive parenting during this pandemic. A "how to" video will also be produced showing parents how to implement some of the practices. Project partners include Abriendo Puertas, the largest U.S. parenting program serving low-income Latinos, and Ivanhoe Broadcasting.
Research questions include: 1) What information do parents need (and potentially what misinformation they are being exposed to)? 2) What are they sharing? 3) How does this vary geographically? 4) Can researchers detect differences in public engagement in geographic areas where TV stations air news videos as compared to areas that don't? This project will use data and communication science research strategies (e.g. natural language processing from online sites where parents are asking questions and sharing information) to inform the content of the videos and lead to the adoption of featured behaviors. Data from web searches, public Facebook pages, and Twitter posts will be used to gain a window into parents' main questions and concerns including information regarding hygiene, how to talk about the pandemic without frightening their children, or determining veracity of what they hear and see related to the pandemic.
This organic approach can detect concerns that parents may be unlikely to ask doctors or discuss in focus groups. Methodologically, the researchers will accomplish this by natural language analysis of the topics that parents raise; the words and phrases they use to talk about specific content; and any references to external sources of information. Where possible, the researchers will segment this analysis by geography to see if there are geographical differences in information needs and discourse. A research brief will share new knowledge gained with the field on how to respond to national emergencies, such as the COVID-19 pandemic, using local TV news and reinforcement of messages across contexts. The findings from this award will provide a knowledge base that can be utilized to better inform responses to national emergencies in the future. By broadly disseminating these findings through a research brief, the project?s innovative research will advance the field of communication science.

How can creators of STEM learning media reach underserved parents and children, and support the kinds of playful STEM interactions that are foundational for future STEM learning?
This research report summarizes findings from a pilot study of Cyberchase: Mobile Adventures in STEM, a program that uses mobile text messaging and short videos to encourage hands-on family learning among low-income Latino families.
In the study, 95 mostly Latino families received weekly text messages with video clips from the popular children's series Cyberchase, and fun activities to do with their
