How to determine a sample size for studying your informal learning program
What’s important to consider when selecting a sample size, or participant group size, for studying your informal (science) education program? What value does a small sample size have? If program managers have ample resources for collecting a lot of data, what factors are important to consider?
Here is a collection of guidelines and examples for use in making an informed decision about determining the sample size for studying your informal learning program. To design a study whose findings are more authentic
When NSTA first adopted guidelines for science competitions in 1999, two of the important questions addressed were whether competitions should be voluntary or required, and whether the emphasis should be on the learning experience or the competition. Our recent research concerning students’ high school science fair experiences has important implications for both of these questions.
Several years ago, we began a systematic and ongoing study of high school science fairs using anonymous voluntary surveys that included a combination of quantitative and qualitative (open-ended text) questions
Science fairs have a remarkable hold on the public’s attention. President Obama, in his 2011 State of the Union address, said, “We need to teach our kids that it’s not just the winner of the Super Bowl who deserves to be celebrated, but the winner of the science fair.” The 2018 film Science Fair won that year’s Sundance Film Festival favorite award. The 2018 book The Class chronicled a year in a classroom where science fairs are at the center of science education. And a recent GEICO “Science Fair of the Future” television commercial had more than 11 million views on YouTube in its first month
Science fairs offer potential opportunities for students to learn first-hand about the practices of science. Over the past six years we have been carrying out voluntary and anonymous surveys with regional and national groups of high school and post high school students to learn about their high school science fair experiences regarding help received, obstacles encountered, and opinions about the value and impact of science fair. Understanding what students think about science fairs will help educators make science fairs more effective learning opportunities. In this paper, we focus on the
The goal of our ongoing research is to identify strengths and weaknesses of high school level science fair and improvements that can help science educators make science fair a more effective, inclusive and equitable learning experience. In this paper, we confirm and extend our previous findings in several important ways. We added new questions to our anonymous and voluntary surveys to learn the extent to which students had an interest in science or engineering careers and if science fair participation increased their interest in science or engineering. And we surveyed a national rather than
The ChemAttitudes project recieved supplemental funding to create materials for train-the-trainer workshops in order to inoculate the chemistry outreach community with members who have the knowledge and resources to train others on strategies for stimulating interest, sense of relevance, and feelings of self-efficacy that were tested in the earlier work of the project. The project team recruited participants from minority serving professional organizations as a strategy for broadening participation. Can it work? Did it work?

Many youth programs seek to understand their influence over time on participant outcomes. This paper offers a methodology for measuring a participant’s perception of a program’s contribution amid their perception of other youth influences such as those from family, school, peer groups, hobbies, and other organized activities. The instrument built on the large body of work on youth influences in order to capture the dominant factors in development of the item bank. In addition to item development, the paper documents face validity followed by content assessment of items using a research panel
Presentation slides and narration for the NARST 2022 Annual Conference. In this presentation we summarize findings from our interviewed with undergraduate STEM majors who identify as Latine, homing in on the ways in which they characterize "STEM" and "STEM people" and their descriptions of K-12 experiences that contributed to their characterizations of these concepts.
Interest is a critical motivating factor shaping how children engage with STEM inside and outside of school and across their lives. In this paper, we introduce the concept of interest catalyst that emerged from longitudinal research with preschool-age children and their families as critical to the process through which each family developed unique interest pathways through their experience with a family-based informal engineering education program. As defined by the team, an interest catalyst is an instance or moment in which an element of the program (or other learning resource or experience)
In collaboration with Metropolitan Family Service (MFS), we conducted a three-year design-based research study to better understand how the characteristics of hands-on, home-based family engineering activities influence how preschool-age children and their parents engage in the engineering design process. Four themes emerged from the study: (1) Families used their imagination and activity narrative elements to set the design context, (2) Families evaluated and revised their solutions based on imagination-driven constraints, (3) Families creatively modified the design space, and (4) Imaginative
This 4-year project addresses fundamental equity issues in informal Science, Technology, Engineering and Mathematics (STEM) learning. Access to, and opportunities within informal STEM learning (ISL) remain limited for youth from historically underrepresented backgrounds in both the United States and the United Kingdom. However, there is evidence that ISL experiences can expand opportunities for youth learning and development in STEM, for instance, increase positive attitudes towards educational aspirations and future careers/pursuits, improve grades and test scores in school settings, and decrease disciplinary action and dropout rates. Through research and development, this project brings together researchers and practitioners to focus on the experiences, practices and tools that will support equitable youth pathways into STEM. Working across conceptual frameworks and ISL settings (e.g. science centers, community groups, zoos) and universities in four urban contexts in two different nations, the partnership will produce a coherent knowledge base that strengthens and expands research plus practice partnerships, builds capacity towards transformative research and development, and develops new models and tools in support of equitable pathways into STEM at a global level. This project is funded through Science Learning+, which is an international partnership between the National Science Foundation (NSF) and the Wellcome Trust with the UK Economic and Social Research Council. The goal of this joint funding effort is to make transformational steps toward improving the knowledge base and practices of informal STEM experiences. Within NSF, Science Learning+ is part of the Advancing Informal STEM Learning (AISL) program that seeks to enhance learning in informal environments and to broaden access to and engagement in STEM learning experiences.
This Equity Pathways project responds to three challenges at the intersections of ISL research and practice in the United States and the United Kingdom: 1) lack of shared understanding of how youth from historically underrepresented backgrounds perceive and experience ISL opportunities across national contexts, and the practices and tools needed to support empowered movement through ISL; 2) limited shared understanding and evidence of core high-leverage practices that support such youth in progressing within and across ISL, and 3) limited understanding of how ISL might be equitable and transformative for such youth seeking to develop their own pathways into STEM. The major goal of this Partnership is for practitioners and researchers, working with youth through design-based implementation research, survey and critical ethnography, to develop new understandings of how and under what conditions they participate in ISL over time and across settings, and how they may connect these experiences towards pathways into STEM. The project will result in: 1) New understandings of ISL pathways that are equitable and transformative for youth from historically underrepresented backgrounds; 2) A set of high leverage practices and tools that support equitable and transformative informal science learning pathways (and the agency youth need to make their way through them); and 3) Strengthened and increased professional capacity to broaden participation among youth from historically underrepresented backgrounds in STEM through informal science learning. The project will be carried out by research + practice partnerships in 4 cities: London & Bristol, UK and Lansing, MI & Portland, OR, US, involving university researchers (University College London, Michigan State University, Oregon State University/Institute for Learning Innovation) practitioners in science museums (@Bristol Science Centre, Brent Lodge Park Animal Centre, Impressions 5, Oregon Museum of Science & Industry) and community-based centers (STEMettes, Knowle West Media Centre, Boys & Girls Clubs of Lansing, and Girls, Inc. of the Pacific Northwest).
Conversations with parents during engagement in informal learning settings, such as museums, can play a critical role in facilitating young children’s early experiences and interest in STEM (Jant et al., 2014; NRC, 2012). There is an acute need to support early STEM engagement for underrepresented families. Successful community partnerships between informal learning settings and Head Start are one way to broaden participation, interest, and success in the STEM fields for underrepresented children and families.
