Projects

This project will develop a learning progression that characterizes how learners integrate and interrelate scientific argumentation, explanation and scientific modeling, building ever more sophisticated versions of practice over time using the three common elements of sense-making, persuading peers and developing consensus. The learning progression is constructed through students’ understanding of scientific practice as measured by their attention to generality of explanation, clarity of communication, audience understanding, evidentiary support, and mechanistic versus descriptive accounts.

This project is developing and testing curriculum materials and a professional development model designed to explore the potential for introducing engineering concepts in grades 3 - 5 through design challenges based on stories in popular children's literature. The research team hypothesizes that professional development for elementary teachers using an interdisciplinary method for combining literature with engineering design challenges will increase the implementation of engineering in 3-5 classrooms and have positive impacts on students.

This project is creating and studying a professional development model to support preK teachers in developing culturally and developmentally appropriate practices in counting and early number. The proposed model is targeted at teachers of children in four-year-old kindergarten, and focuses on culturally relevant teaching and learning. The model stresses counting and basic number operations with the intention of exploring the domain as it connects to children's experiences in their homes and communities.

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.

The project designs and implements technologies that combine artificial intelligence in the form of intelligent tutoring systems with multimedia interfaces (i.e., an electronic science notebook and virtual labs) to support children in grades 4-5 learning science. The students use LEONARDO's intelligent virtual science notebooks to create and experiment with interactive models of physical phenomena.

This project develops a series of interactive on-line games and investigates the effect these games have on increasing middle school science students' and teachers' knowledge and skills of scientific argumentation. There are four areas of argumentation addressed by the games: (1) understanding a claim, (2) judging the evidence about a claim based on type and quality (objectivity, reliability or validity), (3) analyzing the reasoning applied to the claim, and (4) evaluating the claim.

This research and development project develops and tests in the classroom three fifth-grade and two second-grade science units that combine both socio-cultural and socio-cognitive perspectives in order to more fully engage both students and teachers in authentic inquiry and tests the units in second- and fifth-grade classrooms.

This research and development project examines the impact of the Project-Based Inquiry Science (PBIS) middle school science curriculum. The research questions explored will look into efficacy, implementation, and teacher practice. A unique feature of the study’s design is an analytic focus on the conditions needed to implement the curriculum in ways that improve student learning in light of the Framework for K-12 Science Education.

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 will bring together two promising innovations: a high school course entitled Energizing Physics and the BEAR assessment system. The goal of this study is to develop and test a formative assessment system for Energizing Physics that has the potential to enable all students to learn physics, so they can succeed in college.

The Math, Engineering, Science Achievement (MESA) outreach programs are partnerships between K-12 schools and higher education that for over forty years introduce science, mathematics and engineering to students traditionally underrepresented in the discipline. This project examines the influences MESA activities (field trips, guest lecturers, design competitions, hands-on activities and student career and academic advisement) have on students' perception of engineering, their self-efficacy and interest in engineering, and their subsequent decisions to pursue careers in engineering.

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 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 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.

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 developing and implementing a rigorous eighth grade physical science program that utilizes engineering design, LEGO™ robotics and mechanics, and a problem-based learning approach to teach mechanics, waves, and energy.

This project is a four-year, longitudinal, mixed-methods study of 12 school districts’ implementation of elementary mathematics instructional materials. It investigates the relationships among the district level of coherence of implementation, the school level of support for implementation, the school level of use of materials, and the effects on student outcomes.

This project investigates the educational value of computer technologies for learning engineering. The project engages high school students to design, build, and evaluate an energy-efficient model house with the aid of computer simulation and design tools. 

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.

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 addresses biology teachers and students at the high school level, responding to the exponential increases occurring in biology knowledge today and the need for students to understand the experimental basis behind biology concepts. The project studies the feasibility of engaging students in an environment where they can learn firsthand how science knowledge develops in the fields of bioinformatics and DNA science by performing collaborative, simulated experiments to solve open-ended problems.

This project provides visionary leadership to the education community by (a) identifying and analyzing the needs and opportunities for future STEM curriculum development and (b) recommending policy positions and actions by funding agencies and STEM educators regarding the development and implementation of STEM school curricula.

The High Adventure Science project is bringing some of the big unanswered questions in Earth and space science to middle and high school science classrooms. Students will explore the mechanisms of climate change, consider the possibility of life on other planets, and devise solutions to the impending shortage of fresh water. Each curriculum module features interviews with scientists currently working on the same unanswered question.

This project is revising and field testing six existing modules and developing, pilot testing, and field testing two engineering modules for required middle school science and mathematics classes: Catch Me if You Can! with a focus on seventh grade life science; and Creating Bioplastics targeting eighth grade physical science. Each module addresses an engineering design challenge of relevance to industries in the region and fosters the development of engineering habits of mind.

This exploratory research and development project addresses the question, "Can students develop an understanding of the ecological nature of science (ENOS) in high school biology and environmental science classes that is useful and productive in environmental citizenship?" To address this question, the project will identify the essential elements of ENOS, investigate how these can be taught and learned, and explore how ENOS skills and understandings are used to enhance environmental citizenship.
