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.

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.
