My research explores the conceptual development of students in student-centered learning environments. I am interested in the evolution of the system as a whole, including students, tools, teachers, course materials, and the interactions among these components. Another current research interest stems from experience working with prospective and practicing K-12 teachers. Reform methods often encourage the elicitation of students' prior knowledge, but several different notions of what to do with that prior knowledge exist within the community of educational practitioners and researchers. I am currently working to understand how prospective and practicing teachers conceive of students' prior knowledge and how they capitalize on it to empower students to inform their own teaching and as a resource on which students can build.

The Constructing Physics Understanding In a Computer听Supported Learning Environment Project (CPU Project)

In 1991, I began a five-year, NSF-funded project with Fred Goldberg, Patricia Heller, and colleagues. The purpose of the project was to develop materials for a 3-year workshop that could model student-centered pedagogy for teaching physics. The workshop was intended for high school teachers and college professors. During the pilot phase of the project, we implemented these modules in our course for prospective elementary teachers. My doctoral research stemmed from the observations made during the first two years of implementation in a physics course for prospective elementary teachers. Students were videotaped as they worked in groups for the purpose of understanding the role of the computer simulator versus laboratory apparatus in students鈥� construction of physics knowledge, and the role of the construction of students鈥� knowledge in shaping the social and material learning environment.

Constructing Physics Understanding for Prospective听and Practicing Elementary Teachers

In 2001, I began a five-year, NSF-funded project with Fred Goldberg from San Diego State University, and Steve Robinson from Tennessee Tech University. The project builds off the needs that were recognized during implementation of the CPU Project. The purpose of the project is to develop a three-tiered curriculum/professional development package for teaching physics to prospective and practicing elementary teachers, for thinking about students鈥� thinking, and for recognizing and using students鈥� prior knowledge. The third part of the package consists of professional development materials for physics instructors and professional development providers for the curriculum stated above. Research that accompanies this curriculum involves understanding how college physics faculty and prospective and practicing elementary teachers conceive of student prior and evolving knowledge. This understanding will inform the development and iterations of the new curriculum as well as elementary methods instruction in the same way that understanding students鈥� conceptions in physics has informed the community鈥檚 physics curriculum-development over the past 30 years.

My teaching interests are in the related fields of elementary science methods, content and educational research. I am committed to providing an environment, tools, and opportunities for prospective and practicing teachers to develop, modify, and support a strong set of beliefs about science teaching and science learning that will guide their instruction and their participation in science and educational communities. Of central importance is helping prospective and practicing teachers establish beliefs that will allow them to present science as an opportunity that is open to all students.

Courses frequently taught

EDUC 5215: Elementary Science Theory and Methods

This course is designed to provide in-depth science instruction on concepts in physical science, life science, and earth science. The nature and history of science are considered part of science content. A focus on strands within the National Science Education Standards and the American Association for the Advancement of Science Benchmarks for Scientific Literacy provide rich contexts for investigations of appropriate science content, processes and methods for K-6 instruction. The content addressed in this course is generally associated with strands that extend to K-6. A central concern in this course includes strategies for eliciting student's prior knowledge and strategies for using this knowledge to empower students, inform instruction, and enhance student learning.

EDUC 5315: Nature of Science and Science Education

This course is designed for prospective and practicing secondary science teachers. The purpose of the course is to provide teachers with the opportunity to establish a personal system of beliefs about societal influences on science and by science, practices within the scientific community, how truth is established in science, and the meaning of objectivity in science. An important goal for this course is to establish a perspective that distinguishes between ideals, actual practices, and the role of the human in determining scientific truth. Another central focus is on making decisions about the purpose of science education in 6-12 instruction. Teachers are expected to establish a system of beliefs that will allow them to answer questions such as, 鈥淲hy should my students learn physical, life, or earth science?鈥�; 鈥淗ow do I balance preparation for students who will become scientists with preparation for students as critical citizens?鈥�; 鈥淗ow do I provide my students with an understanding of science as a human endeavor in which all types of people participate?鈥�; 鈥淗ow can I use science to help students understand the concept of risk assessment?鈥� Several different perspectives on science and science education are discussed, including sociological perspectives, traditional and inquiry perspectives, multicultural perspectives, and feminist perspectives. It is expected that teachers will draw on the research literature, discussions, and classroom activities to establish, modify, and support a strong set of beliefs that have personal meaning and that will influence their science instruction.
