Projects

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.

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 aims to develop a software diagnostic tool for integrating diagnostic interviews, group administered assessments, and student data in real-time so that teachers can enter and view student status information. This project would concentrate on rational number learning in grades 3-8. The design is based on a model of learning trajectories developed from existing research studies.

This project is developing and evaluating a test form that diagnoses teachers' capacities in two closely connected cases of reasoning about multiplicative relations among quantities: fractions and proportions. Teachers' responses to test items will be informative about their capacities to reason about content in ways that support student’s thinking. The project is developing instruments using a new class of psychometric models called Diagnostic Classifcation Models (DCMs) that are based on categorical latent variables.

The project will develop, pilot, and validate eight discussion-oriented performance tasks that will be embedded in an online simulated classroom environment. The resulting research and development products could be used nationwide in teacher preparation and professional development settings to assess and develop teachers' ability to support classroom discussion in science and mathematics.

This exploratory project develops and tests graphical scaffolds which facilitate high school students' coordination of connecting evidence with alternative explanations of particular phenomena, as well as their collaborative argumentation about these phenomena. At the same time, the project examines how high school students use these tools to construct scientifically accurate conceptions about major topics in Earth and space sciences and deepens their abilities to be critically evaluative in the process of scientific inquiry.

SRI International developed a formative assessment intervention that integrates classroom network technologies and contingent curriculum activities to help middle school teachers adjust instruction to improve student learning of Earth science concepts. The intervention was tested as part of a quasi-experimental study within an urban school district in Colorado that includes ethnically and economically diverse student populations. Findings indicate significant student learning gains for students in implementation classes as compared to students in comparison classes.

The project team is developing, implementing and evaluating a prototype for an integrated assessment system in elementary teacher education in mathematics. The project is documenting both the development of the student teachers in the practice of teaching mathematics to students from diverse backgrounds and of cooperating teachers and field instructors as they learn to analyze the practice of the student teachers and provide feedback.

A principled framework is created for the development of learning progressions in science that can demonstrate how their use can transform the way researchers, educators and curriculum developers conceptualize important scientific constructs. Using the construct of transformation of matter, which requires understanding of both discrete learning goals and also the connections between them, a hypothetical learning progression is constructed for grades 5-12.

This project is developing and testing a curricular learning progression of early algebra objectives and activities for students in grades 3 - 5. The goal of the work is to provide teachers with curricular guidance and instructional resources that are useful in preparing students for success in study of algebra at the middle grade level. The project is also developing and validating assessment tools for evaluating student progress toward essential pre-algebra mathematical understandings.

The goal of this project is to develop a classroom observation tool and an online professional development model to help early-elementary teachers improve science instruction among young learners by cultivating scientific discourse.

One significant challenge facing elementary STEM education is the varied preparation of English-language learners. The project addresses this with an innovative use of engineering curriculum to build on the English-language learners' prior experiences. The project will support teachers' learning about strategies for teaching English-language learners and using engineering design tasks as learning opportunities for mathematics, science and communication skills. 

This project investigates how vignette illustrations minimize the impact of limited English proficiency on student performance in science tests. Different analyses will determine whether and how ELL and non-ELL students differ significantly on the ways they use vignettes to make sense of items; whether the use of vignettes reduces test-score differences due to language factors between ELL and non-ELL students; and whether the level of distance of the items moderates the effectiveness of vignette-illustrated items.

This project focuses on the challenge of using assessment of relevant STEM content to improve K-12 teaching and learning. CLEAR takes advantage of new technologies and research findings to investigate ways that science assessments can both capture and contribute to cumulative, integrated learning of standards-based concepts in middle school courses. The project will research new forms of assessment that document students' accumulation of knowledge and also serve as learning events.

This RAPID project is a cross-national comparative study of U.S. and Chinese instructional support systems, building from earlier data about mathematics teaching and learning in large urban school districts of both the United States and the People's Republic of China. The study uses quantitative methods to compare and contrast the effectiveness of supports (e.g., professional development, teacher networks, school leadership) in improving teachers' instructional practices and student achievement using comparable instrumentation.

This project is developing, validating, and evaluating computer modeling-based formative assessments to improve student learning in chemistry. Activities include developing a series of computer models related to key topics in high school chemistry, developing questions to probe student understanding of matter and energy, identifying teaching and learning resources appropriate for different levels of student conceptual understanding, and developing professional development resources on integrating formative assessments into high school chemistry courses.

The purposes of this conference include bringing together 150 participants from all aspects of STEM education to exchange ideas about research, curriculum, and assessment; to help teachers integrate research-based instructional strategies in their teaching; and to build sustainable collaborations between participants. It includes three days of parallel presentations and discussion followed by a two-day summer academy. A focus on research-based strategies that advance the successful participation of underrepresented groups is embedded in all activities.

In response to the critical need for scholars with deep content knowledge in chemistry and the specialized training to conduct CER, this capacity building project prepares scholars whose research marries expertise in instrument design with extensive literature on chemistry misconceptions, resulting in the development of concept inventories as reliable and valid measures of student learning for use by chemistry teachers (both high school and post-secondary) and chemistry education researchers.

This project aims to engage students in meaningful scientific data collection, analysis, visualization, modeling, and interpretation. It targets grades 9-12 science instruction. The proposed research poses the question "How do learners conceive of and interact with empirical data, particularly when it has a hierarchical structure in which parameters and results are at one level and raw data at another?"

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 implemented a facets-of-thinking perspective to design tools and practices to improve high school chemistry teachers' formative assessment practices. Goals are to identify and develop clusters of facets related to key chemistry concepts; develop assessment items; enhance the assessment system for administering items, reporting results, and providing teacher resource materials; develop teacher professional development and resource materials; and examine whether student learning in chemistry improves in classes that incorporate a facet-based assessment system.

This project draws from the expertise of a fully collaborative educator-scientist team to create learning progressions, curricular units and assessment instruments towards large scale research on the teaching and learning of climate change and impacts by 7-12^th graders in primarily under-resourced schools. Products include eight week curricular units, IPCC-compliant simplified future scenarios, an online interface with guided predictive distribution modeling, and research results.

This CAREER proposal has four objectives: 1) examine the nature of mathematics teachers' learning opportunities for instructional improvement, 2) examine how work contexts influence the quality of teacher learning opportunities, 3) examine the impact of teacher learning opportunities on changes in student mathematics achievement over four years, and 4) work with district and school administrators to promote instructional improvement and student achievement by effectively providing learning opportunities to mathematics teachers.

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.
