Thesis advisor: George M. Barnett / Lifelong science learning is important for making informed decisions on science topics, and there is a need to engage broader and more diverse audiences with science. One opportunity for engagement occurs when students share science topics with a public audience. Research indicates this interaction can have benefits for students, but little is known about the impact it may have on audience members’ thoughts about science. Youth are different from typical sources of science information, and may elicit different reactions. This dissertation examines the impact youth sources may have on adults’ perceptions of and responses to science topics. Young adults (N = 399) were randomly assigned to one of two scenarios. Both scenarios stated two individuals would describe research they had done about local air quality on the news. One scenario identified the individuals as local high school students, and the other as research scientists from a local institution. Dependent variables included perceptions of the warmth and competence of the presenters, expectations of the quality of the information they would share, willingness to take action based on that information, and general trust in scientists. A subset of participants (N=22) was selected for cognitive interviews and asked to explain the thoughts that influenced their survey responses. Results showed multiple reactions to the scenario. Three groups were identified in the perceptions data: one expressed trust in the presenters, one expressed skepticism, and one based their perceptions on personal experiences doing science. Participants said intertwined thoughts about trust in scientists and assumptions about the presenters’ intentions influenced perceptions, with an overall assumption that youth would have good intentions while adults might not. Participants did not appear to separate their expectations of the information from the people who would share it. However, their willingness to take action was related to the action, not the presenter or information. Findings suggest youth may be an avenue for engaging individuals who have lower trust in typical science information sources. Implications for science education and communication are discussed. / Thesis (PhD) — Boston College, 2017. / Submitted to: Boston College.

This study is an examination and evaluation of the outcomes of a series of courses that I helped build to create a graduate certificate. Specifically, I wanted to evaluate whether or not the online iteration of the Informal Science Institutions Environmental Education Graduate Certificate Program truly provided the long term professional development needed to enhance the skills of the formal and informal educators participating so that they could contribute meaningfully to the improvement of science literacy in their respective communities. My role as an internal evaluator provided an extraordinary opportunity to know the intent of the learning opportunities and why they were constructed in a particular fashion. Through the combination of my skills, personal experiences both within the certificate’s predecessor and as an educator, I was uniquely qualified to explore the outcomes of this program and evaluate its effectiveness in providing a long-term professional development for participants. After conducting a literature review that emphasized a need for greater scientific literacy in communities across America, it was evident that the formal education enterprise needs the support of informal educators working on the ground in myriad different settings in ways that provide science as both content and process, learning science facts and doing real science. Through a bridging of informal science educators with formal teachers, it was thought each could learn the culture of the other, making each more fluent in accessing community resources to help make these educators more collaborative and able to bridge the classroom with the outside world. This bridge promotes ongoing, lifelong learning, which in turn can help the national goal of greater scientific literacy. This study provided insight into the thinking involved in the learners’ growth as they converted theory presented in course materials into practice. Through an iterative process of reviewing the course generated content, I was able to piece through the many layers of this two year long program to examine the growth of these individuals over time. While all participants showed growth completing the certificate program, those who could fully invest themselves in the experiences seemed to have gained the most. These cases indicate the Informal Science Institutions Environmental Education Graduate Certificate Program was effective at enhancing the careers of formal and informal science educators. Additionally, it suggests informal science educators, although busy with their professional obligations and personal lives, can be successful in a formal graduate program designed to meet ISE needs as explicated in Learning Science in Informal Environments: People, Places, and Pursuits (Bell, Lewenstein, Shouse, & Feder, 2009). The emergent model indicating connections among a person’s personal life, professional life, and graduate study may also have implications for other professionals desiring to enroll in graduate school. For example, science teachers in university graduate programs may also benefit from applying this model to their lives.

Will student attitudes towards science change when they are given a chance to explore an area of science in which they have indicated an interest? This action research thesis investigated this question over a period of nine weeks. The subjects of this study included twelve students enrolled in the same seventh grade physical science class. The school was located in a suburban setting in the Southeast United States. Data for this study was collected with anecdotal notes, participation grid, science attitude survey, student interviews, and student journals. This study found that when students are given the opportunity to pursue an area of science in which they demonstrate an interest, they are more likely to participate in their regular curriculum and increase positive attitudes' towards science. As a result of this increased engagement and improved attitudes' towards science, students academic performance in science also improved.

Underrepresentation of women and minorities in the science, technology, and engineering (STEM) fields is a perennial concern for researchers and policy-makers. Many causes of this problem have been identified. Less is known about what constitutes effective methods for increasing women’s participation in STEM. This study examines the role that identity formation plays in encouraging girls to pursue STEM education and careers utilizing data from a cohort-based, informal science enrichment program that targets middle-school-aged girls. A Mixed-methods design was employed to examine girls’ science interests, efficacy, attitudes, and identity—referred to as affinities. Quantitative data were collected before and after program participation using science affinity scales. Qualitative data included observations, focus groups, and individual interviews. This study builds on past research conducted on the same program. The study is presented in three components: fidelity of implementation, participant affinities, and science identity theory building. Quantitative and qualitative measures reveal that the program was implemented with high fidelity. Participants had high initial affinities for science as compared to a contrast group. Analysis of qualitative data of science affinities revealed several themes in girls’ attitudes, experiences, and intentions toward science. Emergent themes discussed include girls’ preferences and interests in science, gender and science efficacy, attitudes toward science, and elements of science identities. Archetypes of emergent science identities developed in this study (expert, experimenter, and inventor) inform different ways in which girls engage with and envision science study and careers. Implications for best practice in fostering science engagement and identities in middle-school-aged girls include the importance of hands-on science activities, the need for enthusiastic relatable role models, and an emphasis on deep understanding of scientific principles.

Eldora, Neethi and Seraphina are three young women who work as science interpreters at a large metropolitan museum. Each woman began her tenure at the age of 15, as part of an employment program for low-income and minority youth, and have since grown to become leaders within the program. Using autoethnography (Ellis, 2004) and portraiture (Lawrence-Lightfoot and Hoffman Davis, 1997), I explore the rich cultures and histories that each woman brings to her work, present stories that counter the dominant deficit narratives around diversity in informal science education, and reflect on connections to my own practice. Through a critical pedagogy framework (McLaren, 2009; Kincheloe, 2008), I analyze power and privilege within the institution, and the roles that race, language, and culture play in the dynamics of the workplace. This includes examination of workplace microaggressions, physical barriers to cross-cultural interaction, and technocratic ideologies that limit advancement and sense of belonging. From facing subtle acts of racism to taking on life-changing opportunities for growth, I examine the complex relationships that the women have with the institution, and explore ways that they are becoming agents of change. / Ph.

Abstract This research attempted to understand the experiences of a cohort of informal and formal science educators and informal science institution (ISI) community representatives during and after completion of a pilot graduate certificate program. Informal science educators (ISEs) find limited opportunities for professional development and support which influence their contributions to America's science literacy and school science education. This emergent design nested case study described how an innovative program provided professional development and enabled growth in participants' abilities to contribute to science literacy. Data were collected through interviews, participant observations, and class artifacts. The program by design and constituency was the overarching entity that accounted for members' experiences. Three principal aspects of the ISI certificate program and cohort which influenced perceptions and reported positive outcomes were (1) the cohort's composition and their collaborative activities which established a vigorous community of practice and fostered community building, mentoring, and networking, (2) long term program design and implementation which promoted experiential learning in a generative classroom, and (3) ability of some members who were able to be independent or autonomous learners to embrace science education reform strategies for greater self-efficacy and career advancement. This research extends the limited literature base for professional development of informal science educators and may benefit informal science institutions, informal and formal science educators, science education reform efforts, and public education and science-technology-society understanding. The study may raise awareness of the need to establish more professional development opportunities for ISEs and to fund professional development. Further, recognizing and appreciating informal science educators as a diverse committed community of professionals who positively influence science education for everyone is essential.

Inquiry-based science instruction is a major goal of science education reform. However, there is little research examining how preservice elementary teachers might be motivated to teach through inquiry. This quantitative study was designed to examine the role of background experiences and an inquiry science methods course on interest in science and interest in teaching science. The course included many activities and assignments at varying levels of inquiry, designed to teach content and inquiry methods and to model effective teaching. The study involved analyses of surveys completed by students in the course on their experiences with science before, during, and at the end of the course. The following questions guided the design of this study and analysis of the data: 1.What science background experiences (school, home, and informal education) do participants have and how do those experiences affect initial interest in science? 2.Among the hands-on activities in the methods course, is there a relationship between level of inquiry of the activity and the motivational quality (interesting, fun, and learning) of the activity? 3.Does the course affect participants’ interest and attitude toward science? 4.What aspects of the course contribute to participants’ interest in teaching science and choice to teach science? Descriptive and inferential analysis of a background survey revealed that participants with high and low initial interest in science differed significantly on remembering about elementary school science and involvement in science related activities in childhood/youth. Analysis of daily ratings of each hands-on activity on motivational qualities (fun, interest, and learning) indicated that there were significant differences in motivational quality of the activities by level of inquiry with higher levels of inquiry rated more positively. Pre/post surveys indicated that participants increased in interest in science and a number of variables reflecting more positive feelings about science and science teaching. Regression analysis found that the best predictors for interest in teaching science were experiencing fun activities in the science methods course followed by the interest participants brought to the course. This study highlights the motivational aspects of the methods course in developing interest in science and interest in teaching science.

abstract: As interest in making and STEM learning through making and tinkering continue to rise, understanding the nature, process, and benefits of learning STEM through making have become important topics for research. In addition to understanding the basics of learning through making and tinkering, we need to understand these activities, examine their potential benefits, and find out ways to facilitate such learning experiences for all learners with resources that are readily available. This dissertation is a study of children’s learning while tinkering inspired by the Educational Maker Movement. It is motivated by the projects that children playfully create with broken toys, art and craft resources, and other found objects, and the connections of such activities to learning. Adopting a sociocultural lens this dissertation examines eight to twelve-year-olds’ learning while tinkering in collaboration with friends and family, as well as on their own. Using a case study methodology and studying interactions and transactions between children, materials, tools, and designs this study involves children learning while tinkering over a week-long workshop as well as over the summer in the Southwest. The three hallmarks of this study are, first, an emphasis on sociocultural nature of the development of tinkering projects; second, an emphasis on meaning making while tinkering with materials, tools, and design, and problem-solving; and third, an examination of the continuation of tinkering using newly acquired tools and skills beyond the duration of the workshop. In doing so, this dissertation contributes to the ongoing discussion of children’s playful tinkering, how and why it counts as learning, and STEM learning associated with tinkering. Implications for future learning and the ways in which tinkering connects to children’s everyday fabric of activities are considered. / Dissertation/Thesis / Doctoral Dissertation Learning, Literacies and Technologies 2018

<p>    </p> <p>The first article presents a study that measured exhibit visitors' reported attitudes as measured by an early iteration of the attitudinal learning inventory (ALI) (Watson et al., 2018). The study, which was conducted at the Indiana State Fair and measured visitors’ self-reported attitude changes after visiting an exhibit about hellbender salamanders, found that 73% of survey respondents claimed they would change their behavior and 70% claimed they would tell others what they learned by visiting the exhibit. The second article presents a study that measured visitors' time spent at the exhibit to calculate holding power. Holding power was calculated by dividing the amount of time spent at the exhibit by the minimum amount of time it takes to read the text and interact with the exhibit. The holding power for the <em>What's Bugging Belva? </em>exhibit was favorable at .67 and is compared with exhibits with holding powers of .47 (Boisvert et al, 1995) and .69 (Peart, 1984). The third study gathered visitor data using the validated ALI and analyzed the data using the FREQ procedure (SAS 9.4). The study was conducted at the Indiana State Fair and Purdue Springfest and measured visitors’ responses to an exhibit about animal welfare. At both events, visitors had positive perceptions in the categories of cognitive and general learning, affective learning, behavioral learning, and social learning.  </p>

Our understanding of how the world works is shaped through countless interactions with things in it. These interactions are our first exposure to science. Through them, we learn that heavy things are hard to push and books do not fall through tables. Our interactions are also shaped by the rules of the groups to which we belong (e.g., families, religious organizations, athletic teams). These rules lead us to accept that some things cannot or should not be done, limiting our interactions with the world. At the same time, these rules change our appreciation for what we do experience. Prior research has focused largely on the separate influences of either physical interactions or social interactions, leaving (relatively) unexplored their combined effects. In this dissertation, I describe how adults understand science related to their long-term participation in a recreational road bicycling group. The cyclists demonstrated a rich understanding of gearing and air resistance that paralleled, on a practical level, the explanations taught in school. This understanding was shaped by the cyclists’ years of physical experience interpreted in light of their individual goals for participating. For the cyclists in this study, knowing the science helped them be more efficient and faster riders. In the end, this study supports the idea that productive and valuable learning takes place in many settings and that it is important to account for the relationship between the social and physical aspects of learning when designing instructional experiences.
