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.
This project is funded by the National Science Foundation's (NSF's) Advancing Informal STEM Learning (AISL) program, which supports innovative research, approaches, and resources for use in a variety of learning settings.
In this project, education researchers, environmental scientists, and educators will develop a computer tool to let STEM educators and curriculum developers build local environmental science models. The system will use data about land use to automatically construct map-based simulations of any area in the United States. Users will be able to choose from a range of environmental and economic issues to include in these models. The system will create simulations that ask students to change to patterns of land use -- for example, increasing land zoned for housing, or open land, or industrial development -- to try to meet environmental and social goals. As a result, students will be able to learn about the interaction of environmental and economic issues relevant to their own city, town, neighborhood, or region. These map-based simulations will be incorporated into an existing science, technology, engineering, and mathematics (STEM) education tool, Land Science, in which learners work in a fictional planning office to study how zoning affects economic and environmental issues in a community. Research has shown that Land Science is mode effective when learners are exploring issues in an area near their home, and the current study will investigate how and why local simulations improve environmental science learning. This project is funded by the Advancing Informal STEM Learning (AISL) program which supports work to enhance learning in informal environments by funding innovative research, approaches, and resources for use in a variety of settings.
In this project, the research team will build, test, and deploy a toolkit that will allow informal STEM educators and developers of informal STEM programming to easily adapt an existing environmental science learning environment, which consists of a place-based virtual internship in urban planning and ecology, to their local contexts, learning objectives, and learner populations. Land Science is a virtual internship in which young people explore the environmental and socio-economic impacts of land-use decisions. To do so, they play the role of interns at an urban planning firm developing a new land-use proposal for the city of Lowell, Massachusetts: they read reports, virtually visit sites, determine stakeholder priorities, and use a geographic information system (GIS) model to evaluate the socio-economic and environmental impacts of land-use choices. No one plan can satisfy all stakeholders, so learners must compromise to create an effective plan and justify their decisions. Land Science has been shown to improve civic engagement, interest in eco-social issues, and understanding of scientific models, but it is most effective when the location of the virtual internship is in or near the learners' home town. To improve the accessibility and impact of this effective learning intervention, the interdisciplinary research team, which includes learning scientists, land-use experts, and informal STEM educators, will develop a Local Environmental Modeling toolkit, which will allow educators to change the location of the simulation and the stakeholder groups, zoning codes, and environmental and socio-economic indicators included in the land-use model. The system will ensure that the model produced is functional, realistic, and appropriately complex. The localized versions of Land Science produced by informal STEM educators will be used in a range of contexts and locations, allowing the research team to study the effects of an online, place-based learning intervention on environmental science learning, STEM interest and motivation, and civic engagement.

Often called "self-plagiarism," text recycling occurs frequently in scientific writing. Over the past decade, increasing numbers of scientific journals have begun using plagiarism detection software to screen submitted manuscripts. As a result, large numbers of cases of text recycling are being identified, yet there is no consensus on what constitutes ethically acceptable practice. Text recycling is thus an increasingly important and controversial ethical issue in scientific communication. However, little actual research has been conducted on text recycling and it is rarely addressed in the ethical training of researchers or in scientific writing textbooks or websites. To promote the ethical and appropriate use of text recycling, this project will be conducted in two phases: In Phase 1, the researchers will investigate the ethical, practical, and legal aspects of text recycling as relevant for professional researchers, students, and publishers. In Phase 2, the investigators will produce educational materials and develop model language for text recycling guidelines and author-publisher contracts that can be adapted by educational institutions, research organizations, and publishers.
This project is a multi-institutional, multidisciplinary investigation of text recycling, the reuse of material from one?s previous work in a new manuscript. In Phase 1, the researchers will investigate questions such as these: What do expert researchers, students, and others involved in scientific communication believe to be appropriate practice, and why? Where is there a clear consensus among experts and where is there substantive disagreement? How often do professional scientists actually recycle material, and in what ways? Under what circumstances does text recycling violate publisher contracts or copyright laws? One facet of this research will involve interviewing and surveying experienced STEM faculty, students, journal editors, and others regarding the ethics of text recycling. A second facet will analyze a corpus of published scientific papers to investigate how researchers recycle text in practice and how this has changed over time. The third facet involves analyzing publisher contracts to better understand the rights of publishers and authors regarding text recycling and to assess their legal validity. In Phase 2, the investigators will use findings from Phase 1 to develop, test, and disseminate two kinds of materials: The first are web and print based instructional materials for STEM students (and others new to STEM research) explaining the ethical, legal, and practical issues involved with text recycling, as well as accompanying documents for faculty, administrators, and librarians. The second are model policies and guidelines for text recycling that address appropriate practice in both academic and professional settings. The investigators will obtain feedback on drafts of these materials from potential users and revise them accordingly, after which they will be disseminated.
