Projects

This project is conducting a comprehensive study of professional development models designed for mathematics teachers in grades K-12. The research team will identify key constructs and frameworks within professional development programs and identify types of professional development models. The goals of the project are to encourage researchers and professional developers to reconceptualize mathematics professional development, develop a shared language, and renew discussions on effective professional development for teachers of mathematics.

Doing science requires that students learn to create evidence-based arguments (EBAs), defined as claims connected to supporting evidence via premises. In this CAREER project, I investigate how argumentation ability can be enhanced among middle school students. The project entails theoretical work, instructional design, and empirical work, and involves 3 middle schools in northern Utah and southern Idaho.

This project is designing, developing, and studying an innovative model for professional development (PD) of teachers who use the Scratch computer programming environment to help their students learn computational thinking. The fundamental hypothesis of the project is that engagement in workshops and on-line activities of the ScratchEd professional development community will enhance teacher knowledge about computational thinking, their practice of design-based instruction, and their students' learning of key computational thinking concepts and habits of mind.

This project conducts interdisciplinary research to advance understanding of embodied learning as it applies to STEM topics across a range of current technology-based learning environments (e.g., desktop simulations, interactive whiteboards, and 3D interactive environments). The project has two central research questions: How are student knowledge gains impacted by the degree of embodied learning and to what extent do the affordances of different technology-based learning environments constrain or support embodied learning for STEM topics?

The research and educational activities of this project focus on advancing the field in the area of fraction operation algorithm development. The goal of this research is to identify core mathematical teaching practices that engage and support students in algorithmic thinking associated with fraction operations. The educational product of this work will be written educational materials that can be used to support the general population of teachers in this domain.

This project explores the potential of "Agent-Based Models" to assist learners to acquire environmental science concepts targeted in forthcoming Advanced Placement test standards. The investigators frame the research in a simulated scenario where "green" infrastructure is integrated into urban environments, and they propose how to use a new user interface strategy ("Paper-to-Parameters") that promises unique approaches for understanding the spatial and scalar relationships between simulation elements.

This project develops and assesses the effectiveness of integrating three computation-based technologies into curricular modules: agent-based modeling (ABM), real-world sensing, and collaborative classroom networks. The STEM disciplines addressed are life sciences and physical sciences at middle and high school levels, specifically Evolution, Population Biology/Ecology, Kinetic Molecular Theory, and Electromagnetism.

This project will adapt and study successful discourse strategies used during language arts instruction to help teachers promote mathematically-rich classroom discourse. Of special interest is the use of models to promote mathematics communication that includes English language learners (ELL) in mathematics discourse.The project will result in a full 40-hour professional development module to support mathematics discourse for Grade 2 teachers, with an emphasis on place value, multidigit addition and subtraction, and linear measurement.

This project will explore how new mobile and web-based technologies can support content-rich nomadic inquiry; that is, science inquiry that takes place on-the-go, across integrated K-12 formal and informal settings. Students will begin the inquiry process in the classroom using curricular activities and the Zydeco web software developed in the project to help define goals and questions and to design data collection strategies and categories for use on a field trip to an informal setting.

This project will synthesize existing literature on modeling-based instruction (MBI) in K-12 science education over the last three decades. It will rigorously code and examine the literature to conceptualize the landscape of the theoretical frameworks of MBI approaches, identify the effective design features of modeling-based learning environments with an emphasis on technology-enhanced ones, and identify the most effective MBI practices that are associated with successful student learning through a meta-analysis.

This project is designing, developing, and testing an innovative approach to elementary students' learning in the critical areas of multiplicative reasoning, fractions, and proportional reasoning. The project is building on the successful El'Konin-Davydov (E-D) elementary mathematics curriculum that originated in Russia to develop a curriculum framework that can be implemented in U. S. schools. The ultimate product of the research will be a rational number learning progression consisting of carefully articulated and sequenced learning goals.

This project will design, develop, and test a virtual learning community (VLC) to enhance the ability of first- and fourth-grade teachers to provide mathematics education. The goal is to produce a prototype of a VLC for first- and fourth-grade Everyday Mathematics teachers that integrates three primary elements: (a) learning objects rooted in practice, such as lesson video, (b) community-building tools offered by the internet, and (c) focused content that drives teachers' professional learning in mathematics.

This project is developing and testing a set of 12 curriculum modules designed to engage high school students and their teachers in the process of applying computational concepts and methods to problem solving in a variety of scientific contexts. The project perspective is that computational thinking can be usefully thought of as a specialized form of mathematical modeling.

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.

The University of South Florida is hosting a conference on Research on the Enacted K-12 Mathematics Curriculum. The purpose of the conference is to explicate the theory on mathematics curriculum enactment, defining key constructs and explaining how they are expected to interact, and why, in order to facilitate the systematic accumulation of knowledge about mathematics curriculum enactment that can guide policy and practice.

This research project aims to explore and understand how geographic information systems (GIS) can be used to promote and teach spatial thinking and social science inquiry skills. It addresses the research question: What are effective teaching practices using GIS to teach spatial thinking and social science inquiry in middle-school and undergraduate classrooms? This program will study the effectiveness of teaching practices for social science instruction with GIS in urban public schools for specific learning objectives.

This CAREER project explores interrelated research questions: (1) What understandings of variability can provide conceptual support for the scheme of ideas that underlie statistical inference--making claims about a population on the basis of samples? (2) What conceptions about variability do students bring to study of data analysis and statistical reasoning in middle grades? (3) How can instruction support students in coming to develop understanding and skill in reasoning about variability?

This project provides partial support for the First North American GeoGebra Conference, GeoGebra-NA2010, to be held July 27-28, 2010 at Ithaca College. The global mission of this conference is to build a community of mathematicians, mathematics educators, and classroom teachers who can develop the potential of GeoGebra and other similar software for transformation of mathematics instruction and curricula through creative development, practical experimentation, and research.

The aim of this project is to explore the hypothesis that a curricular focus on quantitative reasoning in middle grades mathematics can enhance development of student skill and understanding about mathematical proof. The project is addressing that hypothesis through a series of studies that include small group teaching experiments with students, professional development work with teachers, and classroom field tests of curricular units that connect quantitative reasoning and proof in algebra.

This project is reviewing and analyzing policy documents and studies related to Algebra I learning and teaching, in order to (1) gain a better understanding of algebra education in the United States; and (2) conduct an accounting of research questions that have and have not been taken up by policy documents to date. The results are to be disseminated to both the mathematics education research community and to the education policy community.

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.

This project will hold a two-day workshop on assessing 21st century skills building on two previous workshops. The previous workshops expressed the need for assessments that can measure the attainment of 21st century skills. This workshop is to describe research on assessment of 21st century skills to inform policies and practices.

This project is examining the relationship between specific technology-based motivational activities and grade 5 to 9 student interest in STEM careers through a variety of classroom-based experiences. The project will test a series of specific hypotheses relating motivation, self-efficacy, STEM career interest, and mathematics learning to activity assignment.

This project convenes two professional mini-conferences and one professional summit to address issues related to the mathematical education of African American students. Research suggests that there is a negative relationship between African American students and mathematics. This relationship is exacerbated by the underrepresentation of African American students in advanced mathematics classes, even when they are the majority of school populations, and the overrepresentation of African American students in lower-track mathematics courses and special education.

This project is convening a series of two professional mini-conferences and one professional summit to address issues related to the mathematical education of African American students, Pre-K-16.
