    This study examined the effects of data-based astrophysical 3D models delivered via computer based interactions, virtual reality, and 3D prints, on spatial reasoning skills and interest in science, technology, engineering, and mathematics (STEM) for females aged 9-12, in particular from underrepresented groups. Underrepresented, or underserved, audiences refer to the demographic status of, and the services that are offered or presented to, segments of a community, typically not currently being served within a larger population that might benefit from such services (Williams et al., 2009). Research to date has not focussed on the development of STEM interests and spatial reasoning skills of young females, particularly at the time when such young learners are forming potential identities in or with STEM and beginning to think about educational and career-related options. STEM interest has been shown to be a critical component of developing a STEM identity, and can be intertwined with issues of confidence and self-efficacy for young female learners (see e.g., Bian et al., 2017; Blotnicky et al., 2018; Fouad, & Smith, 1996; Simpkins et al., 2006). Mental manipulation and understanding of 2D or 3D objects has been posited as an important STEM skill, helping to indicate future mathematical success, science performance, and potential pursuit of STEM careers (Ganley et al., 2014; Hegarty & Waller, 2005; Rafi et al., 2005; Uttal & Cohen, 2012; Verdine et al., 2014). A mixed methods design was used for this research. In Study 1, a qualitative approach examined potential obstacles to and challenges in working in STEM field for females from underrepresented groups. Unstructured interviews with 11 adult females representing diverse groups and various STEM careers yielded important historical perspectives, along with recommendations for building STEM careers for young females today. The recommendations from Study 1 generated three areas that informed the development of Study 2: the critical role of having a strong mentor, role model, or support system in place along the STEM pathway; the need to work with and engage females in STEM activities and subjects when they are as young as possible, preferably while in primary/elementary school; and the importance of developing a sense of STEM self-efficacy in young females. Study 2 was a quantitative study that investigated the overall research question. Participants were three different groups of young female learners (n = 100), ages 9 -12. The participants worked directly with data-based astrophysical 3D models, in short term interventions in formal and informal educational workshop settings. The interventions concatenated concepts driven by current astrophysical data models, providing authentic learning experiences in full and half day formats through coding, 3D modeling, 3D printing and virtual reality, and delivered by women researchers in STEM. The results showed that such interventions that utilized real world data manipulations and 3D applications as part of hands-on activities significantly increased STEM interest for the participants from underserved groups. Results were not significant for increasing spatial ability. The results are discussed in terms of the need to extend exposure to STEM activities and interventions for females younger than middle school, especially in underserved areas, to encourage interest and self-confidence in further STEM education and future careers. The research also offers recommendations on how to better approach the evaluation of and potential improvement of spatial reasoning skills that take into consideration age and cognitive appropriateness. This study holds promise for helping to engage young and underserved females who might otherwise not have confidence in their abilities or even be aware of their potential to contribute in STEM areas

    This study extended research on the development of explanatory labels for astronomical images for the non-expert lay public. The research questions addressed how labels with leading questions/metaphors and relevance to everyday life affect comprehension of the intended message for deep space images, the desire to learn more, and the aesthetic appreciation of images. Participants were a convenience sample of 1,921 respondents solicited from a variety of websites and through social media who completed an online survey that used four high-resolution images as stimuli: Sagittarius A*, Solar Flare, Cassiopeia A, and the Pinwheel Galaxy (M101). Participants were randomly assigned initially to 1 of 3 label conditions: the standard label originally written for the image, a label with a leading question containing a metaphor related to the information for the image, or a label that contained a fact about the image relevant to everyday life. Participants were randomly assigned to 1 image and compared all labels for that image. Open-ended items at various points asked participants to pose questions to a hypothetical astronomer. Main findings were that the relevance condition was significantly more likely to increase wanting to learn more; the original label was most likely to increase overall appreciation; and, smart phone users were more likely to want to learn more and report increased levels of appreciation. Results are discussed in terms of the need to examine individual viewer characteristics and goals in creating different labels for different audiences.Comment: 50 pages, 7 tables, 2 figures, accepted by the journal "Psychology of Aesthetics, Creativity, and the Arts

    A Universe of Sound: processing NASA data into sonifications to explore participant response

    IntroductionHistorically, astronomy has prioritized visuals to present information, with scientists and communicators overlooking the critical need to communicate astrophysics with blind or low-vision audiences and provide novel channels for sighted audiences to process scientific information.MethodsThis study sonified NASA data of three astronomical objects presented as aural visualizations, then surveyed blind or low-vision and sighted individuals to elicit feedback on the experience of these pieces as it relates to enjoyment, education, and trust of the scientific data.ResultsData analyses from 3,184 sighted or blind or low-vision survey participants yielded significant self-reported learning gains and positive experiential responses.DiscussionResults showed that astrophysical data engaging multiple senses could establish additional avenues of trust, increase access, and promote awareness of accessibility in sighted and blind or low-vision communities
