Projects

This project examines the empirical nexus between ELL students' language identity and science identity development. The project addresses the pressing need for empirical studies that combine theoretical perspectives from second language education, linguistics, and science education to understand science identity development among ELLs.

This project explores possibilities for localized change led by parents and caregivers. By making explicit how to foster and increase Black and Latinx parents’ engagement in solidarity with community organizations and teachers, this project could provide a model for other communities and schools seeking to advance racial justice in mathematics education. Through critical community-engaged scholarship and in collaboration with ten Black and Latinx families, ten teachers, and two community organizations, the research team will co-design and co-study two educational programs aimed at advancing racial justice in elementary mathematics.

This study seeks to describe trajectories that describe the ways in which Black learners develop as particular kinds of mathematical learners. The study takes place in the context of an established, multi-year college bridge program that has as its goals to increase the representation of historically marginalized groups in the university community.

This project investigates how to use new touch technologies, like touchscreens, to create graphics and simulations that can be felt, heard, and seen. Using readily available, low-cost systems, the principal investigator will investigate how to map visual information to touch and sound for students with visual impairments.

This project will aim to investigate how to increase equitable and active participation of diverse students' science learning in middle schools. The central premise of this study will be that building upon and integrating diverse students' funds of knowledge into their learning opportunities would contribute to create equitable access to effective participation.

This project will contribute to the understanding of how high school physics can have a positive impact on students' self-perceptions, impacting important educational outcomes in this subject matter. Its focus is on the development of a positive physics identity (self-perceptions with respect to physics in terms of competence, performance, interest, and recognition by others) among high school students, particularly females, as a means to increase current and future engagement with the subject.

This research study expands on the characteristics of mathematical discourse and examines and specifies relationships between descriptive elements across multiple content foci in mathematics. The micro-genetic study is based on examination of video data from multiple routine classroom settings with teachers who demonstrate varying levels of discourse across three curricular topics in mathematics. The resulting framework and redesigned teacher education courses will provide models on which other teacher education programs might build.

This project studies teaching practices in a year-long high school algebra course that integrates hand-held and other electronic devices. Of particular interest is how these technologies can support learners' capacity to efficiently and effectively draw on the distributed intelligences that technical and social networks make available. The investigation focuses on collaborative learning tasks centered on collective mathematical objects, such as functions, expressions, and coordinates that participants in a group must jointly manipulate through networked computers.

This is a Faculty Early Career Development project aimed at developing, implementing, and assessing a model that introduces novice elementary school teachers to community-based engineering design as a strategy for teaching and learning in urban schools. Reflective of the new Framework for K-12 Science Education, the model addresses key crosscutting concepts, disciplinary core ideas, and scientific and engineering practices. It builds on theoretical perspectives and empirical foundations, including situated learning, engineering design cognition, and children's resources and funds of knowledge, including cultural and linguistic diversity.

Covariational reasoning, or the ability to reason about relationships as quantities change together, is one way of thinking that can provide a foundation for students to build their more abstract algebraic knowledge. This research builds a foundation for integrating education and research at the intersection of students’ developing algebraic knowledge, covariational reasoning, and new educational technologies to create a new path into algebra. This path can help remove barriers that have historically restricted access to mathematics and STEM coursework and careers.

The goal of this project is to improve the quality of middle school science in a select number of schools and to gain insight into effective science professional development practice more generally. The project will focus on the following objectives: (1) increasing the quantity and quality of inquiry-based instruction; (2) facilitating the development and implementation of inquiry-based instruction; and (3) improving student achievement in middle school science classrooms.

There have been prominent and widespread calls for high school science students to work with data in more complex ways that better align with and support the work of professional scientists and engineers. However, high school students' analysis and interpretation of scientific data is often limited in scope, complexity, and authentic purpose. This project aims to support and advance students' work with ecological data in high school biology classrooms by embracing a new approach: Bayesian data analysis methods. Such methods involve expressing initial ideas or beliefs and updating them quantitatively with data that students access or record. This project will empower 20 high school teachers and their approximately 1,200 students to make sense of data within and beyond classroom contexts. It also will involve sharing research findings, an educational technology tool for Bayesian data analysis, and curricular resources in open and accessible ways.

Environmental issues like wildfires can serve as effective science learning contexts to promote scientific literacy and citizenship. This project will partner with teachers, teacher educators, and disciplinary experts in data science, fire ecology, public health, and environmental communication to co-design a data-driven, justice-oriented, and issue-based unit on wildfires. In the unit, student will engage in various data practices to gain insights into the issue of wildfires and how it affects their lives and communities. The project seeks to theorize how learners can leverage disciplinary knowledge and practices in environmental and data science as a foundation for making data-informed actions towards a more just and sustainable society.

This CAREER award aims to study the construct of "epistemic empathy" and examine how it can be cultivated in science and mathematics teacher education, how it functions to promote responsive teaching, and how it shapes learners' engagement in the classroom. In the context of this project, epistemic empathy is defined as the act of understanding and appreciating another's cognitive and emotional experience within an epistemic activity aimed at the construction, communication, and critique of knowledge.

This project explores how secondary mathematics teachers can plan and enact learning experiences that spur student curiosity, captivate students with complex mathematical content, and compel students to engage and persevere (referred to as "mathematically captivating learning experiences" or "MCLEs"). The study will examine how high school teachers can design lessons so that mathematical content itself is the source of student intrigue, pursuit, and passion. To do this, the content within mathematical lessons (both planned and enacted) is framed as mathematical stories and the felt tension between how information is revealed and withheld from students as the mathematical story unfolds is framed as its mathematical plot.

This project will design and develop specialized instructional materials and guidelines for teaching secondary algebra in linguistically diverse classrooms. These materials will incorporate current research on student learning in mathematics and research on the role of language in students' mathematical thinking and learning. The work will connect research on mathematics learning generally with research on the mathematics learning of ELLs, and will contribute practical resources and guidance for mathematics teachers who teach ELLs.

This project examines the development of statistical literacy that combines statistical reasoning and thinking. The project will use professional learning communities for teachers to learn about statistical literacy and develop learning experiences for their students. The project will engage students and teachers in finding meaningful ways to use statistical reasoning to make data-based arguments and reason about patterns they observe in society.

Students of color must have access to robust and meaningful opportunities to learn science in classrooms that center their assets and humanity. This project aims to cultivate such spaces through designing and studying teacher professional learning focused on pedagogical practices that engage students of color meaningfully in science learning. These practices leverage students’ assets to foster growth in science and scientific habits of mind. This project will support pre-service and practicing teachers in developing tools for practice and reflection that focus on equity and highlighting the assets of students of color in secondary science.

Elementary students need opportunities to see science as meaningful and relevant to their lives. One way to increase this relevance is with learning experiences that are grounded in community-based questions and inquiries that students identify and carry out themselves. An important contribution of this project is investigating how culturally relevant and community-based science curriculum helps to affirm and develop Black students’ science identities in an urban, elementary classroom. This project will partner with third, fourth and fifth-grade elementary teachers to create and to investigate such learning experiences.

This project will study ways to improve classroom instruction grounded in science practices to address inequities in science education for emerging bilingual students. The project will create research-based resources for teacher educators that focus on developing preservice elementary teachers' understanding and abilities to support emerging bilingual students' engagement in science practices.

This project will support pre-service and in-service teachers in professional development that will prepare them to teach about climate change in community-specific ways. This project aims to advance elementary teachers’ development in three high-impact areas: (a) their self-efficacy toward teaching climate change science or beliefs and attitudes about teaching climate change science; (b) their science content knowledge around climate change; and (c) their climate change identity, or how they view their agency and role in climate change.

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.

Access to high quality STEM education is highly variable depending on where one lives. In addition, early career teachers need support during their first years of teaching to be successful and help them stay in the profession. This project aims to provide in-service and beginning elementary school teachers increased opportunities to refine their mathematics teaching to support minoritized youth in racially diverse rural communities in Georgia that have less access to elementary mathematics specialists. This project follows and supports both beginning teachers (BTs) and elementary mathematics coaches (EMCs) over 5 years to develop and refine their mathematics teaching and coaching, respectively, using equity-based tools to guide reflection and conversations about both the BTs’ instructional practices and the EMCs’ coaching practices.

This project involves a longitudinal, ethnographic study of children's mathematical performances from preschool to first grade in both formal classroom settings and informal settings at school and home. The study seeks to identify opportunities for mathematical learning, to map varied performances of mathematical competence, to chart changes in mathematical performance over time, and to design and assess the impact of case studies for teacher education.

This project investigates the STEM teacher pipeline and examine qualifications, from teacher candidates who express interest in teaching STEM through to the eventual career paths of teachers in the workforce. In doing so, the project examines how the supply of STEM teachers has changed over time, whether the supply is adequate in meeting the needs of a changing nation, the qualifications and credentials of STEM teachers, and the implications of the STEM teacher career paths for equity and serving high needs contexts and students.
