It is estimated that there could be 40 billion earth-sized planets orbiting in the habitable zones of stars in the Milky Way. Major advances in long range telescopes have allowed astronomers to identify thousands of exoplanets in recent decades, and the discovery of new exoplanets is a now a common occurrence. Public excitement for the discoveries grown alongside these discoveries, thus opening new possibilities for inspiring a new generation of scientists and engineers that may dream of one day visiting these planets. This project investigates the use of interactive, intelligent educational technologies to generate interest in STEM by allowing learners to explore and even create their own exoplanets. Research will occur across several informal learning contexts, including summer camps, after school programs, planetarium shows, and at home. The approach is based on the idea of "What if?"questions about Earth (e.g., "What if the Moon did not exist?"), designed to trigger interest in STEM and frame exploratory and elaborative discussions around hypothetical science questions that are subsequently linked to the search for habitable exoplanets. Learners are able to interact with and explore scientifically accurate simulations of alternative versions of Earth, while making observations and posing explanations for what they see. Technology-based informal learning experiences designed to act as triggers for and sustainment of interest in STEM have the potential to plug the leaky STEM pipeline, and thus have profound implications for the future of science and technology in the United States.
The project seeks to advance the science of designing technologies for promoting interest in STEM and informal astronomy education in several ways. First, the project will develop simulations for exploratory learning about astronomy and planetary science. These simulations will present hypothetical worlds based on what-if questions and feasible models of known exoplanets, thus giving learners a chance to better understand the challenges of finding a habitable world and learning about what is needed to survive there. Second, a new PBS NOVA Lab will be developed that will focus on Exoplanet education. This web-based activity has the potential to reach millions of learners and will help them understand how planets are formed and the requirements for supporting life. Learners who use the lab will have an opportunity to invent their own exoplanets and export them for first-person exploration. Third, researchers on the project will design and implement Artificial Intelligence-based pedagogical agents to support learning and promote interest. These agents will inhabit the simulations with the learner, acting as a coach and guide, and be designed to be culturally responsive and personalized based on learner preferences. Fourth, interactive exoplanet-focused planetarium shows, that will involve live interaction with simulations, will take place at the Fiske Planetarium (Boulder, CO). Finally, the project will develop a server-based infrastructure for tracking and supporting long term development of interest in STEM. This back-end will track fine-grained behaviors, including movement, actions, and communications in the simulations. Such data will reveal patterns about how interest develops, how learners engage in free-choice learning activities, and how they interact with agents and peers in computer simulations. A design-based research methodology will be employed to assess the power of these different experiences to trigger interest and promote learning of astronomy. A range of different pathways for interest in STEM will therefore be considered and assessed. Research will measure the power of these experiences to trigger interest in STEM and promote re-engagement over time. Innovation lies in the use of engaging and intelligent technologies with thought-provoking pedagogy as a method for extended engagement of diverse young learners in STEM. Project research and educational resources will be widely disseminated to researchers, designers developers and the general public via peer-reviewed research journals, conference presentations, informal STEM education networks of science museums, children's museums, Fab Labs, and planetariums, and public media such as public television's NOVA science program website.

A team of experts from five institutions (University of Minnesota, Adler Planetarium, University of Wyoming, Colorado State University, and UC San Diego) links field-based and online analysis capabilities to support citizen science, focusing on three research areas (cell biology, ecology, and astronomy). The project builds on Zooniverse and CitSci.org, leverages the NSF Science Gateways Community Institute, and enhances the quality of citizen science and the experience of its participants.
This project creates an integrated Citizen Science Cyberinfrastructure (CSCI) framework that expands the capacity of research communities across several disciplines to use citizen science as a suitable and sustainable research methodology. CSCI produces three improvements to the infrastructure for citizen science already provided by Zooniverse and CitSci.org:
Combining Modes - connecting the process of data collection and analysis;
Smart Assignment - improving the assignment of tasks during analysis; and
New Data Models - exploring the Data-as-Subject model. By treating time series data as data, this model removes the need to create images for classification and facilitates more complex workflows. These improvements are motivated and investigated through three distinct scientific cases:
Biomedicine (3D Morphology of Cell Nucleus). Currently, Zooniverse 'Etch-a-Cell' volunteers provide annotations of cellular components in images from high-resolution microscopy, where a single cell provides a stack containing thousands of sliced images. The Smart Task Assignment capability incorporates this information, so volunteers are not shown each image in a stack where machines or other volunteers have already evaluated some subset of data.
Ecology (Identifying Individual Animals). When monitoring wide-ranging wildlife populations, identification of individual animals is needed for robust estimates of population sizes and trends. This use case combines field collection and data analysis with deep learning to improve results.
Astronomy (Characterizing Lightcurves). Astronomical time series data reveal a variety of behaviors, such as stellar flares or planetary transits. The existing Zooniverse data model requires classification of individual images before aggregation of results and transformation back to refer to the original data. By using the Data-as-Subject model and the Smart Task Assignment capability, volunteers will be able to scan through the entire time series in a machine-aided manner to determine specific light curve characteristics.
The team explores the use of recurrent neural networks (RNNs) to determine automated learning architectures best suited to the projects. Of particular interest is how the degree to which neighboring subjects are coupled affects performance. The integration of existing tools, which is based on application programming interfaces (APIs), also facilitates further tool integration. The effort creates a citizen science framework that directly advances knowledge for three science use cases in biomedicine, ecology, and astronomy, and combines field-collected data with data analysis. This has the ability to solve key problems in the individual applications, as well as benefiting the research of the dozens of projects on the Zooniverse platform. It provides benefits to researchers using citizen scientists, and to the nearly 1.6 million citizen scientists themselves.

Consideration of the needs of individuals with a wide range of disabilities is not always considered in the early design stages of an informal STEM learning (ISL) activity or program. The primary access approach for people with disabilities becomes the provision of accommodations once the ISL product or environment is created. In contrast, the Universal Design approach considers users with a wide range of characteristics throughout the design process and works to create products and environments that are accessible, usable, and inclusive. This project, called AccessISL, led by the University of Washington's DO-IT (Disabilities, Opportunities, Internetworking and Technology) Center and Museology Program, includes an academic museology program and local ISL sites, representing museums, zoos, aquariums, makerspaces, science centers, and other sites of informal STEM learning. Insights will be gained through the engagement of people with disabilities, museology graduate students and faculty, and ISL practitioners. The AccessISL project model, composed of a set of approaches and interventions, builds on existing research and theory in the fields of education science, change management, effective ISL practices, and inclusive design processes. The project will collect evidence of policies and practices (or lack thereof) that improve the inclusiveness of ISL with respect to a wide range of disabilities and considers approaches for the design and development of new strategies; explores what stakeholders need to make change happen; uncovers challenges to the adoption of inclusive practices in public ISL settings and explores ways to overcome them; and proposes relevant content that might be included in museology curriculum. This 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 project addresses the following two objectives:
For ISL personnel and museology faculty: to increase knowledge, skills, and actions to make ISL programs, facilities, courses, and resources more welcoming and accessible to participants with disabilities and embed relevant practices within their work.
For postsecondary STEM students with disabilities and museology students: to increase knowledge and skills in advocating for ISL offerings that are welcoming and accessible to everyone, including those with a wide variety of disabilities, and to encourage individuals with disabilities to pursue careers in ISL.
The project employs a student-centered approach and a set of practices that embrace the social model of disability, social justice education, disability as a diversity issue, intersectionality, and Universal Design. A leadership team of interns--each member a STEM student with a disability or a museology graduate student--along with project staff will engage with the University of Washington's Museology Program to identify and implement strategies for making ISL activities and courses more welcoming and accessible to individuals with disabilities. An online community of practice will be developed from project partners and others nationwide. A one-day capacity building institute will be held to include presentations, student/personnel panels for sharing project and related experiences, and group discussions to explore issues and further identify systemic changes to make ISL programs more welcoming and accessible to individuals with disabilities. As prototypes of the AccessISL Model are developed, evaluation activities will primarily be formative (looking for strengths and weaknesses) and remedial (identifying/implementing changes that could be made to improve the model). The model will continue to be fine-tuned through formative evaluation. Evaluation of the model components will focus on the experience of a range of stakeholders in the project. Specifically, quantitative data collected will include levels and quality of engagement, accessibility recommendations and products developed, and delivery of ISL services. Qualitative data will be collected through observations, surveys, focus groups, interviews, and case studies.
AccessISL project products will include proceedings of an end-of-project capacity building institute, promising practices, case studies, a video, and other online resources to help ISL practitioners and museology faculty that will result in making future ISL opportunities more inclusive of people with disabilities. AccessISL will advance knowledge and ensure long-term impact using multiple strategies:
broadening the STEM participation of people with disabilities as well as women, racial/ethnic minorities, and other underrepresented groups through the application of universal design
strengthening associations and creating synergy and durable relationships among stakeholders,
encouraging teaching about disability, accessibility, and universal design in museology courses,
empowering students with disabilities and current and future ISL practitioners to advocate for accessible ISL and develops an infrastructure to promote accessible ISL programs nationwide, and
contributing to the body of promising practices with products that will (a) enhance understanding of issues related to the inclusion of people with disabilities in ISL programs and (b) promote inclusive practices.
Outcomes will benefit society by making STEM opportunities available to more people and enhancing STEM fields with the talents and perspectives of people with disabilities.

This Research in Service to Practice project will bring together representatives from six long-standing youth programs, experts in the field of out-of-school-time youth programming, and education researchers to collaboratively explore the long-term (15-25 years) impact of STEM-focused, intensive (100+ hours/year), multi-year programming. The six partnering programs have maintained records with a combined total of over 3000 alums who participated between 1995 and 2005. This four-year research project uses an explanatory, sequential, mixed-method design to carry out four steps: (1) identify and describe the impact on the lives of program alums who are now ages 30 to 45; (2) identify causal pathways from program strategies to long-term outcomes; (3) develop an understanding of these pathways from the perspective of the people who experienced them; and (4) disseminate this knowledge broadly to those associated with STEM-focused programming. Research questions include: How did these programs affect youth's lives as they progressed toward and into adulthood? What program strategies and what participant attributes contributed most to the staying power of these effects? What life events and social structures supported and inhibited participant outcomes? This project describes the effects, identifies the causal pathways, and produces materials that programs can use for both strategic planning and generating support resources. Additionally, this project provides research methodology for organizations that want to conduct their own retrospective research and lays a foundation for a more comprehensive study that includes programs without historical documentation. The project aligns with NSF's Big Idea "NSF INCLUDES: Transforming education and career pathways to help broaden participation in science and engineering" by providing essential information about the long-term effect of interventions on educational and career pathways in STEM.
The project's approach involves three phases: (1) research preparation, (2) causal structural modeling of survey data from approximately 2,000 respondents, and (3) rich qualitative follow-up. Human ecological and self-determination theories inform data collection and analyses at every project phase. In the preparation phase, program staff complete program profiles from an historic perspective by identifying program strategies that may have included, for example, scientific research, robotics development, teaching science in informal settings, and working in scientific research labs. In the quantitative phase, the project will recruit alums who attended one of the 6 youth programs between 1995 and 2005 to submit a current resume and complete an online questionnaire, based on the following scaled variables: retrospective recall of basic psychological need satisfaction and frustration in relation to perceived program strategies; STEM identity (at three time periods: pre-program; post-program; and current); current well-being; career influences; and career barriers. The questionnaire also includes open-ended questions about life events related to the following categories: family and friends, school and work, and living conditions. Analysis of the questionnaire will lead to development of a causal structural model. In the qualitative phase, data will be collected from a purposefully selected sample of 30 alums based on findings from the quantitative phase. Methods include interviews, photo journals, and STEM pathways maps. Analysis of interviews, resumes, and photo journals take place within the structure of basic psychological need satisfaction and motivational quality across ecological systems over time. Qualitative analysis uses the constant comparative method, and findings are used to update and refine the final causal structural model and inform overall findings, conclusions, and recommendations of the project.
Since the 1990s, out-of-school time programs have engaged youth from underserved communities in STEM learning and in building interest in STEM careers, yet these programs often based on untested assumptions that participation has lasting effects on education, career, and life choices related to STEM. This Research in Service to Practice project has the potential to 1) guide practitioners in program improvement and improved program outcomes; 2) provide insight into achieving program goals, such as equity, increased well-being of participants, an informed citizenry, and a diversified STEM workforce; and 3) inform multi-stakeholder decision-making with respect to this type of programming. This research also builds a foundation of research data collection and analysis methods to guide and support future research on long term-impacts and youth STEM programming. Dissemination strategies include a website, webinars, video, infographics, conference presentations, and written reports to reach stakeholders including practitioners, researchers, administrators, and funders.

While prior research has explored the reasons adults seek learning opportunities, little is known about the factors that moderate older adults' desire to participate in particular learning experiences. This study will contribute to understanding strategies that engage older adults in STEM learning in informal settings. The specific informal STEM Learning (ISL) experience to be studied here involves the innovative use of a carefully structured multigenerational team engineering design challenge that incorporates the engineering design process, recognized as integrative approach to STEM. The project will develop and pilot new tools to measure the impacts of the ISL experience on older adults. The work will ultimately generate new knowledge that supports general measurement practices through the rigorous, systematic development of measures of older adult learning.
During the 18-month pilot study, the team will: (a) develop and test methods for measuring engagement in informal STEM learning and STEM advocacy in adults 50+ years of age; and (b) explore factors that lead to the engagement of this population in ISL and that moderate the outcome of enhanced STEM advocacy. For research purposes, engagement is being defined as focus, participation, and persistence on a task. STEM advocacy is defined as a stance toward personal actions that supports or promotes a cause or policy. The study design includes use of an intergenerational team engineering design challenge involving 48 older adults as the focal ISL activity of the research. Findings from this pilot study will inform a future large-scale study of ISL environments, including specific instructional practices and resulting outcomes, for older adult learning. Defining the construct of STEM advocacy and examining its validity as a potentially measurable outcome will better position the field to design and evaluate more effective older adult learning experiences.
Project results will be disseminated widely through the literature on ISL, adult education and research tool development, as well as existing practitioner networks. The project's connection with networks of lifelong learning institutes creates additional infrastructure opportunities for ISL experiences, including the broader use of intergenerational learning methods and informal STEM design challenges. This Pilot & Feasibility study 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 program will derive knowledge on extreme weather and its concepts to be shared with youth in the Boston and Kansas City areas. Subsequently, the youth will share this knowledge by displaying it as art work on the rapid transit systems. The art projects will culminate in broad-based exhibition at the end of each group's sessions. The project will involve 200 youth per region resulting in an impact of 1000 youth per year, 80 adult mentors and 20,000 adult transportation riders in learning about extreme weather concepts. Participant organizations are the University of Mass-Boston, University of Mass-Lowell, The Massachusetts College of Art, the University of Kansas Center for Research Inc., and the Goodman Research Group Inc.
The goals of this project are to bring the topic of extreme weather to the foreground by educating youth and in turn having them educate a selected group of adults that use the rapid transit system. Groups of youths will learn about the topic through a series of meetings with mentors who are experts on the issues around extreme weather. The youth will derive their own art-works with their interpretation. These art-works will be displayed on the rapid transit systems in New England (Merrimack Valley and Worcester regions) and the Mid-West (Topeka and Kansas City areas). Using a quasi-experimental mixed methodology (demographics, bus ridership, initial level of science awareness, and interest) the goal is to understand science learning outcomes associated with the creation and public display of youth art. Research questions of importance in this regard are 1. In what ways does blending art with the science enhance youth learning about extreme weather concepts? 2. To what extent does youth art support adult learning of science? and 3. How does regional context affect learning about extreme weather?
Broader impacts will result from the youth diversity as well as the diversity of riders of the rapid transit systems where the art of extreme weather is displayed.

This project responds to calls to increase children's exposure and engagement in STEM at an early age. With the rise of the maker-movement, the informal and formal education sectors have witnessed a dramatic expansion of maker and tinkering spaces, programs, and curricula. This has happened in part because of the potential benefits of tinkering experiences to promote access and equity in engineering education. To realize these benefits, it is necessary to continue to make and iterate design and facilitation approaches that can deepen early engagement in disciplinary practices of engineering and other STEM-relevant skills. This project will investigate how stories can be integrated into informal STEM learning experiences for young children and their families. Stories can be especially effective because they bridge the knowledge and experiences young children and their caregivers bring to tinkering as well as the conversations and hands-on activities that can extend that knowledge. In addition, a unique contribution of the project is to test the hypothesis that stories can also facilitate spatial reasoning, by encouraging children to think about the spatial properties of their emerging structures.
This project uses design-based research methods to advance knowledge and the evidence base for practices that engender story-based tinkering. Using conjecture mapping, the team will specify their initial ideas and how it will be evident that design/practices impact caregivers-child behaviors and learning outcomes. The team will consider the demographic characteristics, linguistic practices, and funds of knowledge of the participants to understand the design practices (resources, activities) being implemented and how they potentially facilitate learning. The outcome of each study/DBR cycle serves as inputs for questions and hypotheses in the next. A culturally diverse group of 300+ children ages 5 to 8 years old and their parents at Chicago Children's Museum's Tinkering Lab will participate in the study to examine the following key questions: (1) What design and facilitation approaches engage young children and their caregivers in creating their own engineering-rich tinkering stories? (2) How can museum exhibit design (e.g., models, interactive displays) and tinkering stories together engender spatial thinking, to further enrich early STEM learning opportunities? and (3) Do the tinkering stories children and their families tell support lasting STEM learning? As part of the overall iterative, design-based approach, the team will also field test the story-based tinkering approaches identified in the first cycles of DBR to be most promising.
This project will result in activities, exhibit components, and training resources that invite visitors' stories into open-ended problem-solving activities. It will advance understanding of mechanisms for encouraging engineering learning and spatial thinking through direct experience interacting with objects, and playful, scaffolded (guided) problem-solving activities.

This commentary explores the kinds of audiences who attend science festivals in the United States by examining data from nearly 10,000 attendees from 24 festivals. Findings are presented to describe festival audiences overall and in comparison to national census and polling data. Results are similar to those for other public science events, with the majority of attendees being well-educated and middle-class. Even so, approximately two thirds of festival-goers are new each year. The findings are discussed in relation to evidence that begins to establish a typology of public science event
This report details the results of a five-year longitudinal study on the Explainer program at the Exploratorium. Explainers from the summer 1999, fall 1999 and spring 2000 cohorts were interviewed before and after their first semester of work as an Explainer, then followed up with additional interviews three more times at intervals of from one to three years. Additional supplemental data were gathered from a larger set of Explainers via surveys that were administered to these same cohorts before and after their first semester of work, and to a set of Explainer alumni who had been out of the

Research shows that science centers and museums play an important role in giving youth STEM learning opportunities (Hamilton, Nussbaum, Kupermintz, Kerkhoven, & Snow, 1995; Salmi, 2001, 2002). These informal learning spaces use interactive exhibits and programming to spur excitement, generate interest in the sciences, shape STEM identities, and support science skills (National Research Council, 2009). A previous Knowledge Base article on engaging diverse youth further details the potential of informal learning to activate STEM interest.
However, despite these encouraging findings, informal
