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.
Projects
This project hypothesizes that learners must have access to the real work of scientists if they are to learn both about the nature of science and to do inquiry themselves. It explores the question "How can informal science education institutions best design resources to support teachers, school administrators, and families in the teaching and learning of students to conduct scientific investigations and better understand the nature of science?"
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 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 is a full research and development project addressing challenge question: How can promising innovations be successfully implemented, sustained, and scaled in schools and districts? The promising innovation is the Science Teachers Learning from Lesson Analysis (STeLLA) professional development (PD) program, which supports 4th- and 5th-grade teachers in teaching concepts in biology (food webs), physical science (phase changes), and earth science (earth’s changing surface, weather).
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.
To meet College and Career-Ready standards in mathematics, classroom instruction must change dramatically. As in past reform efforts, many look to professional development as a major force to propel this transformation, yet not enough is known about mathematics professional development programs that operate at scale in the United States. In this project, we evaluated one such program.
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.
This project is carrying out a research and development initiative to increase the success rates of our most at-risk high school students—ninth-grade students enrolled in algebra classes but significantly underprepared for high school mathematics. It will also result in new understandings about effective approaches for teaching mathematics to struggling students and about effective ways for implementing these approaches at scale, particularly in urban school districts.
This project is developing and evaluating effectiveness of 15 - 20 short computer mediated animations and games that are designed to: (1) increase students' conceptual understanding in especially problematic topics of middle grades mathematics; and (2) increase students' mathematics process skills with a focus on capabilities to think and talk mathematically.
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 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.
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.
The goals of STEM instruction are to educate a populace that is scientifically and mathematically literate and who can solve real-world problems by applying science and mathematics. This exploratory project is designed to study the effectiveness of professional development focused on the integration of mathematics and science instruction, mediated by technology tools, to improve middle school teachers' ability to teach scientific inquiry and mathematical problem solving.
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.
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.
This project will design, develop, and test a virtual learning community (VLC) to enhance the ability of first- and fourth-grade teachers to provide mathematics education. The goal is to produce a prototype of a VLC for first- and fourth-grade Everyday Mathematics teachers that integrates three primary elements: (a) learning objects rooted in practice, such as lesson video, (b) community-building tools offered by the internet, and (c) focused content that drives teachers' professional learning in mathematics.
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 is creating and studying a blended professional development model (face-to-face and online) for mathematics teachers and special educators (grades 4-7) with an emphasis on teaching struggling math students in the areas of fractions, decimals, and positive/negative numbers (Common Core State Standards). The model's innovative design differentiates professional learning to address teachers' wide range of prior knowledge, experiences, and interests.
This project is developing and testing curriculum materials and a professional development model designed to explore the potential for introducing engineering concepts in grades 3 - 5 through design challenges based on stories in popular children's literature. The research team hypothesizes that professional development for elementary teachers using an interdisciplinary method for combining literature with engineering design challenges will increase the implementation of engineering in 3-5 classrooms and have positive impacts on students.
This is a 3.5-year efficacy study of the Developing Mathematical Ideas (DMI) elementary math teacher professional development (PD) program. DMI is a well-known, commercially available PD program with substantial prior evidence showing its impact on elementary teachers' mathematical and pedagogical knowledge. However, no studies have yet linked DMI directly with changes in teachers' classroom practice, or with improved student outcomes in math. This study aims to remedy this gap.
This project is creating and studying a professional development model to support preK teachers in developing culturally and developmentally appropriate practices in counting and early number. The proposed model is targeted at teachers of children in four-year-old kindergarten, and focuses on culturally relevant teaching and learning. The model stresses counting and basic number operations with the intention of exploring the domain as it connects to children's experiences in their homes and communities.
This project recruited high school African American males to begin preparation for science, technology, engineering and mathematics teaching careers. The goal of the program was to recruit and prepare students for careers in secondary mathematics and science teaching thus increasing the number of African Americans students in STEM.
