John Timothy Dunlosky - US grants

As part of NSF's Advancing Informal STEM Learning program, Science Learning+ (SL+) is a partnership among US and UK foundations. SL+ makes grant awards that take transformational steps to inform, improve, and advance the knowledge bases, practices, and design of informal STEM learning experiences and environments. The long-term SL+ goals are to broaden participation in STEM and to better understand, strengthen and coordinate STEM engagement and lifelong learning.

This Science Learning+ Planning Project will develop a prototype assessment tool (based on a mobile technology platform) to map STEM learning experiences across different learning ecologies (e.g. science centers, mass media, home environment) and to develop research questions and designs for a Phase 2 Science Learning+ proposal. The tool will focus on the impact of the learning ecologies on knowledge, interest, identity and reasoning rather than emphasize learning in a specific content area. The proposing team will develop and conduct a small scale usability study during the planning period, which will inform what is proposed in the Phase 2 research.

A key focus of the planning period will be to identify and develop the theoretical constructs (i.e., outcomes) to be measured by the prototype App. As a starting point, the project will start with four of the six strands identified in Learning Science in Informal Environments (National Research Council, Bell et al., 2009): (1) interest triggered by a STEM experience; (2) understanding scientific knowledge; (3) engaging in scientific reasoning; and (4) identifying with the scientific enterprise. Discussion among the project partners during the planning process will revolve around how these strands should be measured in the Phase 2 research across ecologies.

The measurement tool will assess the goal(s) that people set as they engage in STEM learning within each ecology and will measure the individuals' duration and level of engagement. The project will strive to utilize measures that: (1) are nonobtrusive; (2) are embedded in STEM experiences; (3) can be used across ecologies; (4) can be scaled for other ecologies than the ones examined in Phase 2 research; and (5) will be easy to use by researchers and practitioners.

Families play a large role in igniting children's interest in science pathways, but they may not always have access to high-quality materials that demonstrate clear connections between science and their daily lives. This project will address this issue by developing high-interest materials that teach the science of food preparation to families with children ages 7-13. These materials include the following four components: (a) Food Labs, food-based investigations taking place in museums or in food service facilities; (b) take-home kits allowing families to conduct similar types of Food Labs at home; (c) a series of question starters called Promoting Interest and Engagement in Science (PIES) designed to facilitate meaningful family conversations around food preparation; and (d) a mobile app designed to deepen families' understandings of relevant science concepts and containing embedded measures of STEM learning. This project will advance knowledge regarding features of take-home materials that foster family science learning and ignite children's interest in science pathways.

This Innovations in Development Project will result in empirically-tested instructional materials that support families, with children ages 7-13, in conducting scientific investigations and holding scientific conversations related to food preparation. Kent State University, in partnership with The Cincinnati Museum Center and La Soupe, a food service provider for families who face food insecurity, will collaboratively develop and test the four interrelated sets of instructional materials mentioned above that are designed to deepen families' scientific content knowledge related to the chemistry of food preparation. To iteratively design and evaluate these materials, the team will conduct both laboratory and in-vivo experiments using a Solomon design with a pre- and post-demonstration survey. The survey will measure children's interest, knowledge, and engagement. For a month after interacting with instructional materials, families will document their science activity at home through the app. Additionally, through analyzing audio-recordings, the team will determine whether and how families ask questions using the PIES materials. Finally, post-demonstration interviews with participating families will focus on the usability and accessibility of the instructional materials. Quantitative and qualitative analyses of the pre-post surveys, interview transcripts, and audio-recordings will be used to improve the instructional materials, and the revised materials will be re-assessed using the same experimental methods and outcome measures. The final set of instructional materials will be developed and widely disseminated for easy use at other science museums, food service providers, and in families' homes. This project leverages partnerships to generate empirical knowledge on features of learning environments that support family science learning and engagement, resulting in empirically-based materials designed to broaden participation in science. 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.

This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
