Projects

This project contributes to the emerging knowledge base for reform-minded middle school STEM instructional materials development through the development, field-testing, and evaluation of a prototype instructional materials module specifically designed to stimulate and sustain urban-based students’ interest in STEM. The module includes guided inquiry-oriented activities thematically linked by the standards-aligned concept of energy transfer, which highlight the fundamental processes and integrative nature of 21st century scientific investigation.

We developed and tested two ecology case study units for urban high school students underserved in their connection to nature. The case studies, based on digital media stories about current science produced by the American Museum of Natural History, use current scientific data to link ecological principles to daily life and environmental issues. Preliminary testing results show that treatment students made significantly higher gains than the control students on the project's major learning goals.

This project is conducting repeated randomized control trials of an approach to high school geometry that utilizes Dynamic Geometry (DG) software and supporting instructional materials to supplement ordinary instructional practices. It compares effects of that intervention with standard instruction that does not make use of computer drawing tools.

This project investigates how high school students' understanding about design thinking compares to that of experienced practitioners and whether participation in a multiyear sequence of courses focused on engineering correlates with changes in design thinking. The project builds upon the Standards for Technological Literacy and courses developed at the University of Colorado and the University of Maryland, Baltimore County.

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 is developing and testing a prototype electronic teacher's guide for a 12-week genetics unit in the NSF-funded curriculum titled Foundation Science: Biology to determine how it impacts high school teachers' learning and practice. The electronic guide, which is based on an existing print guide, has a flexible design so that it anticipates and meets the curriculum planning and support needs of teachers with different knowledge/skills profiles.

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 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 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.

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 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 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 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.

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?

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 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.

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 will address the question: In what ways can research on learning inform the design of interfaces and technology tools to be used by students accessing large scientific data bases? Oceans of Data will (1) conduct a systematic survey of the widely-dispersed research literature and (2) develop and disseminate a knowledge status report, a resource offering guidance for making these large scientific data bases accessible to and usable by high school science classes.

This project is using innovative Geospatial Information Technology-based learning in high school environmental science studies with a focus on the meteorological and ecological impacts of climate change. The resources developed are using ArcGIS Explorer Desktop and Google Earth software applications to increase students' learning and interest in science and careers and will be adaptable for teachers to improve classroom implementation.

This project will develop a mathematics course for the fourth year of high school. The new course is being designed for students who will enter post-secondary education and will major in programs not requiring Calculus. The new course includes mathematics from a problem-solving or applications perspective, and serves as a bridge to college mathematics and statistics. Unit topics include functions, modeling, algebraic strategies, binomial distributions, and information processing.

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 uses items and data from the Program for International Student Assessment (PISA) to develop two kinds of resources for preparation and professional development of secondary mathematics teachers: one in the form of prototype professional learning materials and a second in the form of PISA-based, research-grounded articles written for mathematics teachers and teacher educators. Work on both resources will focus on algebra and quantitative literacy and on factors influencing educational equity.

This project will investigate how complex systems concepts supported by innovative curricular resources, technology applications and a comprehensive research and development structure can assist student learning in the domain of biology by providing a unifying theme across scales of time and space. The project seeks to address four areas of critical need in STEM education: biological sciences, complex systems, computational modeling, and equal access for all.

This project integrates American Sign Language (ASL) into the life and physical sciences content of 9th-12th grade deaf or hard-of-hearing students. Project partners incorporate the use of the assistive technology in order to develop, research, and disseminate two interactive 3D dictionaries: Signing Life Science Dictionary (SLSD), and Signing Physical Science Dictionary (SPSD) with audio modes and approximately 750 standards-based terms in English and Spanish text that can be signed or listened to on demand.
