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 is developing and conducting research on the Cohort Model for addressing the mathematics education of students that perform in the bottom quartile on state and district tests. The predicted outcome is that most students will remain in the cohort for all four years and that almost all of those who do will perform well enough on college entrance exams to be admitted and will test out of remedial mathematics courses.

The SAVE Science project is creating an innovative system using immersive virtual environments for evaluating learning in science, consistent with research- and policy-based recommendations for science learning focused around the big ideas of science content and inquiry for middle school years. Motivation for this comes not only from best practices as outlined in the National Science Education Standards and AAAS' Project 2061, but also from the declining interest and confidence of today's student in science.

This project is developing a science teacher education model focused on the establishment of a diagnostic learning environment through formative assessment as a powerful instructional practice for promoting learning of all students (grades 5–12) on the topic of energy with the goal of increasing the understanding of the processes through which teachers develop the requisite knowledge, skills, and dispositions for effective deployment of a formative assessment instructional cycle.

This project uses computer-based models of interacting organisms and their environments to support a learning progression leading to an appreciation of the theory of evolution and evidence that supports it. The project has created a research-based curriculum centered on progressively complex models that exhibit emergent behavior. The project will help improve the teaching of complex scientific topics and provide a reliable means of directly assessing students' conceptual understanding and inquiry skills.

We are analyzing the intended algebra curriculum as represented in a variety of high-school mathematics textbooks – Core Plus Mathematics Project (CPMP), Discovering Mathematics (Key Curriculum Press), EDC's Center for Mathematics Education, Glencoe, Interactive Mathematics Program (IMP), and University of Chicago School Mathematics Project (UCSMP). The textbook analysis is based on two dimensions frequently used for curriculum analysis: a content dimension and a cognitive dimension.

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.

The goal of this project is to accelerate the progress of early-career and pre-service science teachers from novice to expert-like pedagogical reasoning and practice by developing and studying a system of discourse tools. The tools are aimed at developing teachers' capabilities in shaping instruction around the most fundamental science ideas; scaffolding student thinking; and adapting instruction to diverse student populations by collecting and analyzing student data on their thinking levels.

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.

Several small-scale experimental classroom studies Star and Rittle-Johnson demonstrate the value of comparison in mathematics learning: Students who learned by comparing and contrasting alternative solution methods made greater gains in conceptual knowledge, procedural knowledge, and flexibility than those who studied the same solution methods one at a time. This study will extend that prior work by developing, piloting, and then evaluating the impact of comparison on students' learning of mathematics in a full-year algebra course.

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.

Geometry Assessments for Secondary Teachers (GAST) represents a collaborative partnership among faculty and staff at the University of Louisville, the University of Kentucky, Florida State University, Alpine Testing Solutions, and Horizon Research, Inc. to develop a knowledge framework and assessments for secondary mathematics teachers' geometry knowledge for teaching. The framework for the assessments will be designed to collect validity evidence for predicting effective geometry teaching and improving student achievement.

This project will define and synthesize effective feedback strategies that can be linked to specific features of daily classroom assessment practices. It will develop a framework, including a conceptual strand (will conceptualize feedback practice considering intrinsic and contextual dimensions) and a methodological strand (used to describe and evaluate the feedback studies and findings to be synthesized). The framework will provide a shared language within and across multiple forms of research in various disciplines.

This project is using data from interviews with 160 K-12 students and 20 adults to describe common understandings and progressions of development for negative number concepts and operations. The project is motivated by the widely acknowledged finding that students have difficulty mastering key concepts and skills involved in work with integers.

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 exploring how curricula and assessment using dynamic, interactive scientific visualizations of complex phenomena can ensure that all students learn significant science content. Dynamic visualizations provide an alternative pathway for students to understand science concepts, which can be exploited to increase the accessibility of a range of important science concepts. Computer technologies offer unprecedented opportunities to design curricula and assessments using visual technologies and to explore them in research, teaching, and learning.

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 focuses on practicing and preservice secondary mathematics teachers and mathematics teacher educators. The project is researching, designing, and developing materials for preservice secondary mathematics teachers that enable them to acquire the mathematical knowledge and situated rationality central to teaching, in particular as it regards the leading of mathematical discussions in classrooms.

The Data Games project has developed software and curriculum materials in which data generated by students playing computer games form the raw material for mathematics classroom activities. Students play a short video game, analyze the game data, develop improved strategies, and test their strategies in another round of the game.

This project is developing a system for producing automated professional mentoring while students play computer games based on STEM professions. The project explores a specific hypothesis about STEM mentoring: A sociocultural model as the basis of an automated tutoring system can provide a computational model of participation in a community of practice, which produces effective professional feedback from nonplayercharacters in a STEM learning game.

This project is assessing the capacities needed by elementary teachers for productive use of mathematics curriculum materials. The project is guided by the assumption that well-designed curriculum programs have the potential to contribute to improvement in mathematics learning opportunities in K-12 classrooms. Yet, minimal research has examined the kind of knowledge and capacities necessary for teachers to use these resources productively. The project will undertake such research and develop tools to assess these capacities.

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.

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 developing a two-year, intensive professional development model to build middle-grades mathematics teachers’ knowledge and implementation of formative assessment. Using a combination of institutes, classroom practice, and ongoing support through professional learning communities and web-based resources, this model helps teachers internalize and integrate a comprehensive understanding of formative assessment into daily practice.
