Projects

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 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 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.

In response to the increased use of formative assessment practices in California's PK-12 mathematics classrooms, this project will investigate what formative assessments are in use, how practitioners and students are utilizing these assessments, and how they impact performance on summative state assessments. The main outcome of this study will be a set of research-informed and field-tested conclusions, recommendations, guidelines, and tools for the development and use of new or improved PK-12 mathematics formative assessments.

This project investigated the professional development needed to make teachers comfortable teaching with multi-user simulations and communications that students use every day. The enactment with OpenSim (an open source, modular, expandable platform used to create simulated 3D spaces with customizable terrain, weather and physics) also provides an opportunity to demonstrate the level of planning and preparation that go into fashioning modules with all selected cyber-enabled cognitive tools framed by constructivism, such as GoogleEarth and Biologica.

Colorado’s PhET project and Stanford’s AAALab will develop and study learning from interactive simulations designed for middle school science classrooms. Products will include 35 interactive sims with related support materials freely available from the PhET website; new technologies to collect real-time data on student use of sims; and guidelines for the development and use of sims for this age population. The team will also publish research on how students learn from sims.

This project is studying the impact of implementing a NSF-funded, high school mathematics curriculum that emphasizes mathematical habits of mind. This curriculum focuses on ways of thinking and doing mathematics in contrast with curricula that focus on mathematical topics. The project is studying the development of teachers' mathematical knowledge for teaching and their capacity to align their instruction with the new curriculum.

This project leverages curricular module development to design, develop, and test new cyberlearning modules that integrate multiple (circulation, respiration, and digestion) systems of the human body. The project aims to deepen science content knowledge, science inquiry skills, and model-based reasoning skills for high school biology students. The project will use simulations showing how individual systems function, how they work together, and how the integration of all three creates a dynamic and reactive biological system.

This is an efficacy study to determine if partnerships among formal and informal organizations demonstrate an appropriate infrastructure for improving science literacy among urban middle school science students. The study aims to answer the following questions: How does participation in the program affect students' science knowledge, skills, and attitudes toward science; teachers' science knowledge, skills, and abilities; and families engagement in and support for their children's science learning and aspirations?

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 project explores the use of cyberinfrastructure to significantly enhance the delivery and quality of professional development for grades 8-12 engineering, technology, and design educators. The goal of the project is to study whether the use of highly interactive cyberinfrastructure increases the educator's teaching competencies and how to effectively teach. Student achievement is measured by comparing state assessments in: the curriculum's technology, engineering, and design assessment, end-of-grade mathematics assessment, and end-of-grade science assessment.

This project scales and further tests the Target Inquiry professional development model. The model involves teachers in three core experiences: 1) a research experience for teachers, 2) materials adaptation, and 3) an action research project. The original program was implemented with high school chemistry teachers, and was shown to result in significant increases, with large effect sizes, in teachers' understanding of science inquiry and quality of instruction, and in science achievement of those teachers' students.

This project is supporting and investigating the implementation of reformed mathematics instruction at the middle school level in two large school districts. The primary goal of the project is to develop an empirically grounded theory of action for implementing reform at school and district levels. The researchers are investigating reform within a coherent system that focuses on leadership and school-based professional development.

The research goal of this project is to evaluate whether an early childhood science education program, implemented in low-income preschool settings produces measurable impacts for children, teachers, and parents. The study is determining the efficacy of the program on Science curriculum in two models, one in which teachers participate in professional development activities (the intervention), and another in which teachers receive the curriculum and teachers' guide but no professional development (the control).

This project scales and further tests the Target Inquiry professional development model. The scale-up and further testing would involve adding physics, biology and geology at Grand Valley State University, and implementing the program at Miami University with chemistry teachers. The project is also producing a website of instructional materials for middle and secondary science.

This is an exploratory study to identify critical aspects of effective science formative assessment (FA) practices for English Language Learners (ELLs), and the contextual factors influencing such practices. FA, in the context of the study, is viewed as a process contributing to the science learning of ELLs, as opposed to the administration of discrete sets of instruments to collect data from students. The study targets Spanish-speaking, elementary and middle school students.

This project is conducting a longitudinal study of the effects of a pre-service elementary science education.  Through overlapping studies on the pre-service teachers (PSTs) and in-service teachers who are graduates of the program, this project is seeking to analyze the impact of three essential dimensions of teacher preparation: inquiry-based science content courses, science methods/practicum courses, and k-12 mentor teachers.

This research study is examining the persistence of improved teacher skills achieved during the K-2 Science & Technology Assistance for Rural Teachers and Small Districts project (K-2 STARTS). K-2 STARTS provided four years of professional development to teachers in 16 rural school districts with high populations of traditionally underserved students. Project data indicates that the project increased teacher content knowledge, pedagogical content knowledge, abilities to integrate science and literacy and to use research-based instructional strategies.

This project will test the efficacy of using agent-based simulation and visualization models to identify the factors that predict mathematics achievement for students from the 8th grade to the 12th grade and beyond. The team is using data that includes 14 years of data on student grade reports, coursework, demographics, teacher variables such as years of service, professional development courses taken, years of service, and other artifacts.

In this project, investigators will convene a group of 15 African American science educators, scientists, and doctoral student scholars and assign them to small work groups to design and conduct multi-site micro-research studies on learning activities that promote science learning and teaching. Work groups will investigate different learning and teaching approaches used in K-12 rural and urban school settings to identify effects on student science learning using quantitative, qualitative, or mixed design studies.

This project is studying measurement practices from pre-K to Grade 8, as a coordination of the STEM disciplines of mathematics and science. This research project tests, revises and extends learning trajectories for children's knowledge of geometric measurement across a ten-year span of human development. The goal will be to validate all components of each learning trajectory, goal, developmental progression, and instruction tasks, as well as revising each LT to reflect the outcomes of the experiments.

This study examines the impact of the newly revised Advanced Placement (AP) Biology and Chemistry courses on students' understanding of and ability to utilize scientific inquiry, on students' confidence in engaging in college-level material, and on students’ enrollment and persistence in college STEM majors. The project provides estimates of the impact of students' AP-course taking on their progress into postsecondary educational experiences and their intent to continue to prepare to be future engineers and scientists.

This exploratory project examines how teachers of second grade students scaffold the development of student conceptual models and their understanding of the nature of scientific models and modeling processes in physical science conceptual areas associated with the particulate nature of matter. This foundational research provides descriptive exemplars that can be shared in both the research literature and in practitioner publications as examples of what cognitively rich pedagogy can achieve.

The goal of this Transforming STEM Learning project is to comprehensively describe models of 20 inclusive STEM high schools in five states (California, New Mexico, New York, Ohio, and Texas), measure the factors that affect their implementation; and examine the relationships between these, the model components, and a range of student outcomes. The project is grounded in theoretical frameworks and research related to learning conditions and fidelity of implementation.
