This Research Advanced by Interdisciplinary Science and Engineering (RAISE) project is supported by the Division of Research on Learning in the Education and Human Resources Directorate and by the Division of Computing and Communication Foundations in the Computer and Information Science and Engineering Directorate. This interdisciplinary project integrates historical insights from geometric design principles used to craft classical stringed instruments during the Renaissance era with modern insights drawn from computer science principles. The project applies abstract mathematical concepts toward the making and designing of furniture, buildings, paintings, and instruments through a specific example: the making and designing of classical stringed instruments. The research can help instrument makers employ customized software to facilitate a comparison of historical designs that draws on both geometrical proofs and evidence from art history. The project's impacts include the potential to shift in fundamental ways not only how makers think about design and the process of making but also how computer scientists use foundational concepts from programming languages to inform the representation of physical objects. Furthermore, this project develops an alternate teaching method to help students understand mathematics in creative ways and offers specific guidance to current luthiers in areas such as designing the physical structure of a stringed instrument to improve acoustical effect.
The project develops a domain-specific functional programming language based on straight-edge and compass constructions and applies it in three complementary directions. The first direction develops software tools (compilers) to inform the construction of classical stringed instruments based on geometric design principles applied during the Renaissance era. The second direction develops an analytical and computational understanding of the art history of these instruments and explores extensions to other maker domains. The third direction uses this domain-specific language to design an educational software tool. The tool uses a calculative and constructive method to teach Euclidean geometry at the pre-college level and complements the traditional algebraic, proof-based teaching method. The representation of instrument forms by high-level programming abstractions also facilitates their manufacture, with particular focus on the arching of the front and back carved plates --- of considerable acoustic significance --- through the use of computer numerically controlled (CNC) methods. The project's novelties include the domain-specific language itself, which is a programmable form of synthetic geometry, largely without numbers; its application within the contemporary process of violin making and in other maker domains; its use as a foundation for a computational art history, providing analytical insights into the evolution of classical stringed instrument design and its related material culture; and as a constructional, computational approach to teaching geometry.

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. This AISL project investigates how informal programs can broaden participation by building social capital in STEM for youth from underrepresented groups. The project integrates social network analysis with research on informal learning, and draws on a framework to connect learning across a variety of sectors. It builds on evidence that sponsorship of youth interest, affinity-based mentorship, and brokering connections to other settings and opportunities can build social capital and support interest and persistence in STEM. It represents a strategic and timely investment into research that solidifies these emerging insights from research and practice, conducting focused investigation into relational supports for STEM interests that are particularly well suited to informal programs.
The project is guided by two research questions: (1) What forms of social capital are tied to persistence in and connecting across informal STEM programs for youth from underrepresented groups? (2) What program features--specifically sponsorship, mentorship, and brokering--grow these social supports for persistence in and connecting across informal STEM programs for underserved youth? These questions are addressed through a mixed methods 18-month cross-sectional study of 200 students in three informal programs in Orange County, California that offer project-based engineering and coding programs, support mentorship, and focus on groups underrepresented in STEM. The sample will include three age categories, capturing the transition to high school, persistence during high school, and transition to college and career. Teens will be interviewed three times at 6-month intervals, spanning these transitions. The goal of this research and effort is to determine if social capital plays an extra ordinary role in learning by this group.

This project by California State University San Marcos and their collaborators will expand and continue to innovate on a pilot Mobile Making program with the goal of developing a sustainable, regional model for serving underserved, middle-school aged youth in twelve after-school programs in the San Diego region. Evaluation of the current Mobile Making program has documented positive impacts on participants' interest, self-efficacy, and perception of the relevance of Making/STEM in everyday life, and led to a model for engaging underserved youth in Making. The work will focus on implementing the program model sustainably at greater capacity by increasing the number of undergraduate activity leaders, after-school sites, and level of community engagement. The expanded Mobile Making program is expected to engage ~1800 middle school youth at 12 local school sites, with activities facilitated by ~1020 undergraduate CSU-SM STEM majors. The sites are in ethnically diverse and economically disadvantaged neighborhoods, with as many as 90% of students at some sites qualifying for free or reduced price lunch. The undergraduate facilitators are drawn from CSU-SM's diverse student body, which includes 44% underrepresented minorities. Outcomes are expected to include increases in the youth participants' interest, self-efficacy, and perception of the relevance of Making/STEM in everyday life. Positive impacts on the undergraduate facilitators will include broadened technical skills, increased leadership and 21st century skills, and increased lifelong interest in STEM outreach/informal science education. The program is designed to achieve sustainability through innovative means such as involving undergraduate facilitators via Community Service Learning (rather than paid positions), and increased community engagement via development and support of a community of practice including local after-school providers, teachers, Makers, and University members. Evaluation of the program outcomes and lessons learned are expected to result in a comprehensive model for a sustainable, university-based after-school Making program with regional impact in underserved communities. Dissemination to other regions will be leveraged via CSU-SM's membership in the California State University (CSU) system, yielding a potential statewide impact. The support of the CSU Chancellor's Office and input from a CSU implementation group will ensure the applicability of the model to other regional university settings, identify common structural barriers and solutions, and increase the probability of secondary implementations. This work 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.
