Research suggests non-experts associate different content with the terms “global warming” and “climate change.” We test this claim with Twitter content using supervised learning software to categorize tweets by topic and explore differences between content using “global warming” and “climate change” between 1 January 2012 and 31 March 2014. Twitter data were combined with temperature records to observe the extent to which temperature was associated with Twitter discussions. We then used two case studies to examine the relationship between extreme temperature events and Twitter content. Our

Glaciers around the world are undergoing dramatic changes. Many people, however, have a limited understanding of the scope of these changes because they are geographically distant and difficult to visualize. Although both digital learning tools and online scientific data repositories have greatly expanded over the last decade, there is currently no interface that brings the two together in a way that allows the public to explore these rapidly changing glacial environments. Therefore, to both improve public understanding and provide greater access to already existing resources, the project team will develop the Virtual Ice Explorer to encourage informal learning about glacial environments. This web application will feature an immersive virtual environment and display a suite of environmental data for an array of Earth's glacial systems. An interactive globe will allow users to select from a collection of sites ranging from polar regions to tropical latitudes. Each featured site will offer users an opportunity to interact with (1) a 3D rendering of the landscape; (2) a local map of the site; (3) historical and contemporary photographs of the site; (4) background information text describing the location, past research, and climate impacts; and (5) available environmental data. One of the most original features of the application will be its realistic, immersive 3D rendering of glacial landscapes by combining very high-resolution digital elevation models and satellite imagery with the application's built-in capabilities for immersive virtual environments. Although immersive environments often require expensive equipment, we are maximizing accessibility by developing the Virtual Ice Explorer to run in a web browser and function across various devices. Thus, the application will be available to anyone with internet access, and they can explore at their own pace.
As part of the successful development of Virtual Ice Explorer, the project team will create a platform for digital elevation models to be visualized and explored in 3D by users within the web application; curate digital elevation models, maps, images, text, and environmental data for inclusion in the web application for up to 11 geographically diverse glaciers/glacial landscapes; iteratively user-test the web application with project partners; and design the architecture of the system to readily scale to a larger collection of glaciers/glacial landscapes. To extend dissemination of the final products, the team has partnered with the U.S. Geologic Survey to showcase four benchmark glaciers in their long-term Glaciers and Climate project. In addition to improving understanding of glacier systems in informal learning environments, the project team will explore applications for spatial learning, employment of 3D environments for educational interventions, and use of Virtual Ice Explorer in formal learning environments. 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. The project also has support from the Office of Polar Programs.

The intent of this five-year project is to design, deliver, and study professional development for Informal Science Learning (ISL) educators in the arena of equity-focused STEAM (Science, Technology, Engineering, Art, and Mathematics) teaching and learning. While the strategy of integrating art and science to promote interest, identity, and other STEM-related learning has grown in recent years, this domain is still nascent with respect to a guiding set of best practices. Through prior work, the team has developed and implemented a set of design principles that incorporate effective practices for broadening participation of girls in science via science-art integration on the topic of the biology, chemistry and optics of "Colors in Nature." The continued initiative would impact the ISL field by providing a mechanism for ISL educators in museums, libraries and after-school programs to adopt and implement these STEAM design principles into their work. The team will lead long-term (12-18 months) professional development activities for ISL educators, including: 1) in-person workshops that leverage their four previously developed kits; 2) online, asynchronous learning activities featuring interactive instructional videos around their STEAM design principles; 3) synchronous sessions to debrief content and foster communities of practice; and 4) guided design work around the development or redesign of STEAM activities. In the first four years of the project, the team will work with four core institutional partners (Sitka Sound Science Center, Sno-Isle Libraries, the Fairbanks North Star Borough School District after-school program, and the Pima County Public Library system) across three states (Alaska, Washington, and Arizona). In the project's later stages, they will disseminate their learning tools to a broad, national audience. 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.
The project has three main goals: (1) To support ISL educators in offering meaningful STEAM activities, (2) To create institutional change among the partner organizations, and (3) To advance the ISL field with respect to professional development and designing for STEAM Programming. The research questions associated with the professional development activities address the ways in which change occurs and focus on all three levels: individual, institutional, and the ISL field. The methods are qualitative and quantitative, including videotaped observations, pre and post interviews, surveys and analysis of online and offline artifacts. In addition, the project evaluation will assess the implementation of the project's professional development model for effectiveness. Methods will include observations, interviews, surveys and Website analytics and program data.
As part of its overall strategy to enhance learning in informal environments, the Advancing Informal STEM Learning (AISL) program funds innovative research, approaches and resources for use in a variety of settings. The project will derive a nationwide online coaching/mentoring program for out of school educators in rural settings. The program builds on a Noyce Foundation pilot project. The issue to be addressed is that educators in rural settings are challenged in a multitude of ways due to isolation. This project will try to find ways to alleviate some of the consequences of isolation through resource sharing, knowledge sharing, and unique techniques for communicating with students. Partners in this effort are the Maine Mathematics and Science Alliance, the National AfterSchool Association, Development Without Limits, and the Maine State Library.
By using widely-available technologies, this project will bring fully online instructional coaching in STEM to out-of-school educators who live too remotely to attend ongoing in-person workshops. The project team will achieve this by adapting a highly promising coaching program where groups of educators video-record their own work with youth, practice key skills, and meet regularly to discuss their work. The project will: (a) test technical challenges to achieve fully virtual implementation; (b) design and adapt a specific STEM-skill curriculum to align with different levels of need; (c) customize the model to work with rural librarians; and (d) integrate the work into existing state and national accreditation systems.
As part of its overall strategy to enhance learning in informal environments, the Advancing Informal STEM Learning (AISL) program 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. The goal of this project is to make 21st century quantum science comprehensible and engaging to non-expert informal adult learners. This project has strong potential to add new knowledge about the public's perception and understanding of quantum physics. This scientific content is often difficult for informal audiences to grasp, and there are relatively few accessible learning resources for a non- professional audience. The development of this online, interactive resource with short animations, graphics, and simulations has strong potential to fill this gap. It will develop a visually driven online resource to engage non-expert audiences in understanding the basics of quantum physics. The web design will be modular, incorporating many multimedia elements and the structure will be flexible allowing for future expansion. All content would be freely available for educational use. There is potential for extensive reach and use of the resources by informal adult learners online as well as learners in museums, science centers, and schools. Project partners are the Joint Quantum Institute at the University of Maryland and the National Institute of Standards and Technology, College Park. An independent evaluation of the project will add new knowledge about informal learners' perceptions and/or knowledge about quantum science and technology. An initial needs assessment via focus groups with the general public will be designed to find out more about what they already know about quantum physics topics and terminology, as well as what they want to know and what formats they prefer (games, simulations, podcasts, etc.). In person user testing will be used with early versions of the project online resource using a structured think-aloud protocol. Later in year 1 and 2, online focus groups with the general public will be conducted to learn what they find engaging and what they learned from the content. Iterative feedback from participants during the formative stage will guide the development of the content and format of the online resources. The Summative Evaluation will gather data using a retrospective post-survey embedded with a pop-up link on the Atlas followed by interviews with a subset of online users. Google Analytics will be used to determine the breadth and depth of their online navigation, what resources they download, and what websites they visit afterward. A post-only survey of undergraduate and graduate students who participated in resource development will focus on changes in students' confidence around their science communication skills and level of quantum physics understanding.
The Exploratorium’s livestream of the August 2017 Total Solar Eclipse reached over 63 million people. Live programs in English and Spanish provided an informal learning experience outside the museum. Over 2.75 million people viewed on-demand videos on eclipse science. Sixty major media providers rebroadcast the livestream telescope feed.
Edu, Inc. conducted a summative evaluation of the NASA-funded project. The study reveals that the Exploratorium successfully disseminated eclipse science and STEM content through media channels and a mobile app, delivering a museum experience to online
In March of 2016, a total solar eclipse occurred in the southwestern pacific; and in August of 2017, a total solar eclipse occurred across a broad swath of the United States. The Exploratorium launched a 2.5 year public education program—Navigating the Path of Totality—that used these two total solar eclipses as platforms for sparking public engagement and learning about the Sun, heliophysics, and the STEM content related to both. These sequential eclipses provided an unprecedented opportunity to build and scaffold public engagement and education. Our strategy was to start the public engagement process with the 2016 eclipse, nurture that engagement with resources, activities and outreach during the 17 months between the eclipses, so that audiences (especially in the U.S., where totality was visible in multiple areas across the country) would be excited, actively interested, and prepared for deeper engagement during the 2017 eclipse. For the August 2017 eclipse, the Exploratorium produced live telescope and program feeds from Madras, OR and Casper, WY. The Exploratorium worked with NASA to leverage what was a once-in-a-lifetime experience for millions to bring heliophysics information and research to students, educators, and the public at large through a variety of learning experiences and platforms.
The core of this project was live broadcasts/webcasts of each eclipse. To accomplish these objectives, the Exploratorium produced and disseminate live feeds of telescope-only images (no commentary) of each eclipse originating them from remote locations; produce and disseminate from the field live hosted broadcasts/webcasts of each eclipse using these telescope images; design and launch websites, apps, videos, educator resources, and shareable online materials for each eclipse; design and deliver eclipse themed video installations for our Webcast studio and Observatory gallery in the months that lead up to each eclipse and a public program during each eclipse; and conduct a formative and summative evaluation of the project.
These broadcasts/webcasts and pre-produced videos provide the backbone upon which complementary educational resources and activities can be built and delivered. Programs and videos were produced in English and Spanish languages. As a freely available resource, the broadcasts/webcasts also provide the baseline content for hundreds if not thousands of educational efforts provided by other science-rich institutions, schools, community-based organizations, and venues. Platforms such as NASA TV and NASA website, broadcast and online media outlets such as ABC, NBC, CBS, CNN, MSNBC and PBS, as well as hundreds of science institutions and thousands of classrooms streamed the Exploratorium eclipse broadcasts as part of their own educational programming, reaching 63M people. These live broadcasts were relied upon educational infrastructure during total solar eclipses for institutions and individuals on the path and off the path alike.
WNET, working with Education Development Center, will lead a small scale Innovations in Development effort to develop, research, and evaluate a new model to engage underserved families in STEM learning. The new endeavor, Cyberchase: Mobile Adventures in STEM, will build on the proven impact of the public media mathematics series Cyberchase and the growing potential of mobile technology and texting to reach underserved parents. WNET will produce two new Cyberchase episodes for 6-9 year olds, focused on using math to learn about the environment. Drawing on these videos and an existing Cyberchase game, the team will produce a bilingual family engagement campaign that will combine an in-person workshop followed by a 6-8 week "text to parent" campaign, in which parents receive weekly text messages suggesting family STEM activities related to the media content. The engagement model will be piloted in three cities with large low-income/Latino populations, along with one texting campaign offered without the workshop. This project will build knowledge about how to deploy well-designed public media assets and text messaging to promote fun, effective STEM learning interactions in low-income families. While past research on educational STEM media has tended to focus on children, especially preschool age, this project will focus primarily on text messaging for parents, and on learners age 6-9, and the wider scope of parent/child STEM interactions possible at that age.
The primary goal of the project will be to develop, test and refine a family engagement model that includes a face-to-face workshop, rich narrative Cyberchase content, and text-message prompts for parents to engage in short, playful STEM activities with children. The project team will explore which features of the mobile text-and-media program have most value for low-income and Latino families and prompt STEM learning interactions, including a comparison of workshop-based and text-only variants. The project will have three phases: needs assessment and preliminary design; an early-stage test in New York and development and testing of media; and three late-stage tests in contrasting locations, two including workshops and one "text-only," and analysis of findings. Ultimately, the project will share knowledge with the field about the opportunities and challenges of using mobile texting and public media to reach underserved families effectively. This knowledge will also inform a future proposal for production and outcomes research, which, based on the study results, may include a scaled-up version in ten locations and a ten-city Randomized Control Test. 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.
Polar Extremes: Enhancing Experiential Digital Learning is an integrated media and research project produced by the PBS science series, NOVA, that will bring polar science to informal learners through traditional storytelling and experiential, digital learning environments. Stark, cold, and seemingly frozen in time, the top and bottom of the Earth feel other-worldly, completely removed from our everyday existence. Yet, nothing could be further from the truth. The Arctic and Antarctic exert profound influence over our entire planet. Disturbances in these icy realms can send transformative ripples around the globe, altering the circulation of the atmosphere and oceans, and affecting every form of life. And although the poles might seem constant and everlasting, they--like our planet--are always changing, with a deep and complex past. NOVA will provide informal science learners access to specialized research happening at the ends of the earth, introducing them to today's scientists exploring the major drivers of the climate, uncovering the deep history of past paleoclimates, or perfecting climate and weather models. The project includes: a 2-hour nationally broadcast PBS documentary (working title Polar Extremes); a NOVA Polar Lab, an experiential interactive learning platform on polar science; and a Polar Exploration Initiative consisting of a 10-part YouTube series, a collection of 360 videos, virtual field trips, and social media reporting "on location" from Antarctica, along with other polar-themed video, radio and digital journalism. It also includes a research program conducted in collaboration with the University of California, Santa Barbara (UCSB) to study how narrative-driven and experiential learning can foster informal learning in polar science across a diverse array of audiences. NOVA, the most popular science program on television, with a robust digital presence, will bring current polar science to millions. NOVA will use a range of media to transport viewers to remote polar locations, to interact with polar scientists, manipulate polar data, or vicariously explore the frozen tundra--using a mix of learning approaches. This project will develop and test the impact of two forms of informal learning: traditional narrative-driven storytelling and active, experiential learning. Both components will be developed through audience research, formative evaluation or pilot testing, and experiments. The overarching goal is to determine the best way to combine and leverage traditional and interactive media technologies to educate the public about polar science. How can these modes enhance learning outcomes? The study uses the Informal Science Learning "strand framework" developed by the National Research Council in Learning Science in Informal Environments: People, Places, and Pursuits (2009). Because different age groups and socioeconomic backgrounds may engage differently with different types of learning materials and platforms, the project components are designed to test a variety of different learning approaches, with different audiences. This study will be one of the first to address the relative efficacy of various forms of experiential education and whether active versus vicarious experiential learning depends on the characteristics of the learners. As engagement technologies continue to evolve, this project will help inform how to best design and apply them effectively. The project will apply these new lessons specifically to present polar research to the public and to offer audiences an opportunity to explore and learn about these remote regions in new ways that bring them to life, make them relevant, and enhance learning outcomes. 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. The project has co-funding support from the Office of Polar Programs (OPP).

Women continue to be underrepresented in computer science professions. In 2015, while 57% of professional occupations in the U.S. were held by women, only 25% of computing occupations were held by women. Furthermore, the share of computer science degrees going to women is smaller than any STEM field, even though technology careers are the most promising in terms of salaries and future growth. Research suggests that issues contributing to this lack of computer science participation begin early and involve complex social and environmental factors, including girls' perception that they do not belong in computer science classes or careers. Computer science instruction often alienates girls with irrelevant curriculum; non-collaborative pedagogies; a lack of opportunities to take risks or make mistakes; and a heavy reliance on lecture instead of hands-on, project-based learning. Computer science experiences that employ research-based gender equitable best practices, particularly role modeling, can help diminish the gender gap in participation. In response to this challenge, Twin Cities PBS (TPT), the National Girls Collaborative (NGC) and Code.org will lead Code: SciGirls! Media for Engaging Girls in Computing Pathways, a three-year project designed to engage 8-13 year-old girls in coding through transmedia programming which inspires and prepares them for future computer science studies and career paths. The project includes five new PBS SciGirls episodes featuring girls and female coding professionals using coding to solve real problems; a new interactive PBSKids.org game that allows children to develop coding skills; nationwide outreach programming, including professional development for informal educators and female coding professionals to facilitate activities for girls and families in diverse STEM learning environments; a research study that will advance understanding of how the transmedia components build girls' motivation to pursue additional coding experiences; and a third-party summative evaluation.
Code: SciGirls! will foster greater awareness of and engagement in computer science studies and career paths for girls. The PBS SciGirls episodes will feature girls and female computer science professionals using coding to solve real-world challenges. The project's transmedia component will leverage the television content into the online space in which much of 21st century learning takes place. The new interactive PBSKids.org game will use a narrative framework to help children develop coding skills. Drawing on narrative transportation theory and character identification theory, TPT will commission two exploratory knowledge-building studies to investigate: To what extent and how do the narrative formats of the Code: SciGirls! online media affect girls' interest, beliefs, and behavioral intent towards coding and code-related careers? The studies aim to advance understanding of how media builds girls' motivation to pursue computer science experiences, a skill set critical to building tomorrow's workforce. The project team will also raise educators' awareness about the importance of gender equitable computer science instruction, and empower them with best practices to welcome, prepare and retain girls in coding. The Code: SciGirls! Activity Guide will provide educators with a relevant resource for engaging aspiring computer scientists. The new media and guide will also reside on PBSLearningMedia.org, reaching 1.2 million teachers, and will be shared with thousands of educators across the SciGirls CONNECT and National Girls Collaborative networks. The new episodes are anticipated to reach 92% of U.S. TV households via PBS, and the game at PBSKids.org will introduce millions of children to coding. The summative evaluation will examine the reach and impact of the episodes, game and new activities. PIs will share research findings and project resources at national conferences and will submit to relevant publications. 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.
As part of its overall strategy to enhance learning in informal environments, the Advancing Informal STEM Learning (AISL) program funds innovative research, approaches, and resources for use in a variety of settings. The project will bring together science museum visitor experience developers, visitor studies staff, indoor location technology developers, cyber-learning researchers, and STEM informal learning specialists for a two day conference, COMPASS (Conference on Mobile Position Awareness Systems and Solutions), to address the achievements and potential of indoor location aware mobile (ILAM) technology in science museums. The pre-conference work, the conference itself, and a subsequent e-publication will provide multiple, informed perspectives and knowledge around ILAM for science museums to develop apps for visitors' own smartphones to enhance and personalize the visitor experience and to experiment with new kinds of inquiry-based learning. The goals of the conference are to form an integrated vision by consolidating expertise from disparate disciplines connected to ILAM tech development, to transform visitor mobile tools to provide more innovative forms of interaction and personalization, and to open new avenues for visitor research with automated data collection and analysis.
The COMPASS conference will bring together 80 participants for two days in September 2018 at the Exploratorium in San Francisco, CA. The first dissemination will take place in a presentation at the ASTC conference the following month in October 2018. A webinar sharing insights from COMPASS and inviting others to engage will be held in March 2019 hosted by ASTC and accessible by ASTC members and non-members alike. A companion COMPASS e-publication will be released for free download, also in March 2019, with summaries of conference proceedings, key issues identified, case histories of ILAM in museums, white papers and other resources. Conference outcomes include establishing a community of practice or special interest group and establishing common goals for future collaborative work. By gathering a diverse range of perspectives and expertise to share research and evidence based findings, COMPASS include collective problem solving and an informed cross disciplinary approach to planning and implementing ILAM technology in the museum environment. The conference will explicitly address the benefits and quality of open source code and protocols and how techniques could be shared among institutions. As professional experience with deploying ILAM apps grows, this tool could be used to increase accessibility for diverse visitor populations, put in use at smaller and medium sized science centers, and applied to a variety of research studies, increasing the impact for funders and benefiting the science center community at large.
As a part of its overall strategy to enhance learning in informal environments, the Advancing Informal STEM Learning (AISL) program funds research and innovative resources for use in a variety of settings. This Broad Implementation project would scale up the CryptoClub Project, an afterschool and online program designed to engage middle school youth in mathematics and cryptography. The project builds on previous successful work and evaluation that is ready for scale up using a train-the-trainer model implemented through a partnership with the National Girls Collaborative. The project will train 160 new CryptoClub leaders who will then train 800 new leaders at 20 hub sites reaching 9600 students. In addition, professional development modules and webinars will continue to refresh leader skills. Other project components include an online multiplayer cryptography game, weekly challenges through social media, and digital cryptology badges for students.
The research uses a think-aloud method with students as they actually attempt to solve the cryptology problems using mathematical thinking. Three think-aloud studies will be performed during the Project. The research team will code transcripts of the interviews for evidence of the mathematical thinking intended to be addressed by each activity, as well as capturing unexpected kinds of thinking. Tasks will also be rated according to the type of knowledge elicited. A written report will include statistical analyses of the think-aloud and interview responses, interpreted in light of the overall CryptoClub goals. The findings will contribute to both future research efforts and practice. The evaluation by EDC uses a quasi-experimental design, which assesses project outcomes for trainers, leaders, students, and Internet users. EDC will also investigate the fidelity to the CryptoClub model as it is scaled up. These studies have strong potential for informing numerous other projects that are at a stage where scale up is under consideration.
