Projects
This is a continuing research project that supports (1) creation of what are termed "ink inscriptions"--handwritten sketches, graphs, maps, notes, etc. made on a computer using a pen-based interface, and (2) in-class communication of ink inscriptions via a set of connected wireless tablet computers. The primary products are substantiated research findings on the use of tablet computers and inscriptions in 4th and 5th grade math and science, as well as models for teacher education and use.
This project is investigating the learning that can take place when elementary school students are directly involved in the collection, sense-making, and analysis of real, personally-meaningful data sets. The hypotheses of this work are that by organizing elementary statistics instruction around the study of physical activities, students will have greater personal engagement in data analysis processes and that students will also develop more robust understandings of statistical ideas.
This project will document factors explaining variations in science achievement across schools enrolling ethnically and linguistically diverse students. The research question is: what leadership and organizational features at the school level are associated with mitigating science achievement gaps? At the conclusion of the five-year project, the findings will take the form of recommendations about leadership practices and school organization that can be implemented in other school settings.
This CAREER proposal has four objectives: 1) examine the nature of mathematics teachers' learning opportunities for instructional improvement, 2) examine how work contexts influence the quality of teacher learning opportunities, 3) examine the impact of teacher learning opportunities on changes in student mathematics achievement over four years, and 4) work with district and school administrators to promote instructional improvement and student achievement by effectively providing learning opportunities to mathematics teachers.
The goal of the project is to inform the development of an impact-based research methodology (IBR) to enable a more direct and overt connections between academic research on games and the development of educational products and services that are sustainable and scalable.
The objective of this project is to develop a toolkit of resources and practices that will help inservice middle grades mathematics teachers support mathematical argumentation throughout the school year. A coherent, portable, two-year-long professional development program on mathematical argumentation has the potential to increase access to mathematical argumentation for students nationwide and, in particular, to address the needs of teachers and students in urban areas.
This project addresses the need for a computationally-enabled STEM workforce by equipping teachers with the skills necessary to prepare students for future endeavors as computationally-enabled scientists and citizens, and by investigating the most effective ways to provide this instruction to teachers. The project also addresses the immediate challenge presented by NGSS to prepare middle school science teachers to implement rich computational thinking experiences within science classes.
This project will study five elementary STEM schools from across the U.S. that are inclusive of students from underrepresented groups in order to determine what defines these schools and will use an iterative case study replication design to study the design and implementation of five exemplary eSTEM schools with the goal of developing a logic model that highlights the commonalities in core components and target outcomes across the schools, despite the different school contexts.
The goal of this project is to improve the implementation of rigorous instructional materials in middle-grades mathematics at scale through a system of practical measures and routines for collecting and using data that both assesses and supports implementation.
This project lays the foundation and framework for enabling digital, multimodal tactile graphics on touchscreens for individuals with visual impairments (VI). Given the low-cost, portability, and wide availability of touchscreens, this work promotes the use of vibrations and sounds on these readily available platforms for addressing the graphical access challenge for individuals with VI. An open-source vibration library has been created and fundamental perceptual building blocks (e.g.\ shapes, lines, critical points, line width and gaps, etc.) guiding how basic graphical components should be rendered on these platforms is being disseminated.

This project is focused on the work and learning of teachers as they engage youth from underrepresented groups in studying chemistry as a subject relevant to heavy metal contamination in their neighborhoods. The project will position Chicago teachers and students as Change Makers who are capable of addressing the crises of inequity in science education and environmental contamination that matter deeply to them, while simultaneously advancing their own understanding and expertise. The project will examine the malleable factors affecting the ability of teachers to engage underrepresented students in innovative urban citizen science projects with a focus on the synergistic learning that occurs as teachers, students, scientists, and community members work together on addressing complex socio-scientific issues.
This project will explore the learning of mathematics through architectural tasks in an online simulation game, E-Rebuild. In the game-based architectural simulation, students will be able to complete tasks such as building and constructing structures while using mathematics and problem solving. The project will examine how to collect data about students' learning from data generated as they play the game, how students learn mathematics using the simulation, and how the simulation can be included in middle school mathematics learning.
This project will examine the impact on mathematics learning of an initiative to provide kindergartners in an urban school district with personal tablet devices that include free, widely available digital mathematics resources. The research questions examine how teachers use table-based mathematics resources during instruction, how caregivers and children engage with table-based mathematics resources, and how the resources then relate to kindergartners mathematics learning.
This project will design, develop, and test a new curriculum unit for high school chemistry courses that is organized around the question, "How does chemistry shape where I live?" The new unit will integrate relevant Earth science data, scientific practices, and key urban environmental research findings with the chemistry curriculum to gain insights into factors that support the approach to teaching and learning advocated by current science curriculum standards.
This proposal will develop and test an open-access, online system of professional development for high school biology teachers in order to build pedagogical competencies for teaching about complex systems and to support the application of those competencies in high school biology classrooms.
The project plans to develop and study a series of metacognitive strategies that support learning and engagement for struggling middle school students during makerspace experiences. The study will focus narrowly on establishing a foundational understanding of how to ameliorate barriers to engaging in design learning through the use of metacognitive strategies. The project plans to translate and apply research on the use of metacognitive strategies in supporting struggling learners to develop approaches that teachers can implement to increase opportunities for students who are the most difficult to reach academically.
This project will research how elementary (K-5) teachers in the Teacher Engineering Education Program (TEEP) program progress in one particular aspect of responsive teaching, noticing student thinking. Project research will also contribute to literature on how to support responsive teaching in web-based environments, expanding understanding of how design principles and features developed in in-person professional development settings can be implemented online. The project will refine a program for engineering teachers nationwide, identify key features that are effective in developing teachers' practice, and create video resources for other professional development programs to use.
This project focuses on the research and develop an engineering education technology and pedagogy that will support project-based learning of science, engineering, and computation concepts and skills underlying the strategically important "smart" and "green" aspects of the infrastructure. The project will develop transformative technologies and curriculum materials to turn the campus of a high school or a geographical information system such as Google Maps into an engineering laboratory with virtually unlimited opportunities for learning and exploration.
This project will work in partnership with the Santa Clara Unified School District (SCUSD) to adapt a previously designed Professional Learning (PL) model based on the District's objectives and constraints to build the capacity of teacher leaders and a program coordinator to implement the adapted PL program. The project is examining the sustainability and scalability of a PL model that supports the development of teachers' pedagogical content knowledge and instructional practices. The project is contributing knowledge about how to build capacity in districts to lead professional learning in science that addresses the new teaching and learning standards and is responsive to the needs of their local context.

The Next Generation Science Standards (NGSS) emphasize the integration of scientific knowledge and the practices of science, a recognition that science classrooms are complex learning environments. Meeting this expectation requires teachers to move beyond traditional routines of practice to become adaptive experts who can adjust their teaching to maximize learning in varied classroom situations. The project will work with teachers to implement a three-year professional development program to assist teachers in the development of adaptive expertise through implementation of an argument-based inquiry approach.
