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.
Projects
This project will (1) identify the characteristics and needs of college-level target learners and their instructors with respect to evolution, (2) articulate the components for expanding the Understanding Evolution (UE) site to include an Undergraduate Lounge in which students and instructors will be able to access a variety of evolution resources, (3) develop a strategic plan for increasing awareness of UE, and (4) develop a strategic plan for maintenance and continued growth of the site.
Current curriculum materials for elementary science students and teachers fail to provoke the following essential questions during science instruction: What is evidence? Why do you need evidence? The goal of this project is to identify whether and how elementary school students formulate answers to these questions and develop concepts of evidence and understandings of the nature of scientific evidence.
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?"
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 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 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, conjecture improved strategies, and test their strategies in another round of the game.
This project is studying effects of linguistically sensitive science instructional materials by translating, enhancing, and evaluating culturally relevant and linguistically appropriate Collaborative Online Projects (originally written in Spanish) for middle school Spanish-speaking English Language Learners.
This project contributes to the emerging knowledge base for reform-minded middle school STEM instructional materials development through the development, field-testing, and evaluation of a prototype instructional materials module specifically designed to stimulate and sustain urban-based students’ interest in STEM. The module includes guided inquiry-oriented activities thematically linked by the standards-aligned concept of energy transfer, which highlight the fundamental processes and integrative nature of 21st century scientific investigation.
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 refining and testing two case study units on contemporary issues in ecology for urban middle and high school students underserved in their connection to nature. The case studies are based on two Science Bulletins, digital media stories about current science produced by the American Museum of Natural History (AMNH), which use current scientific data to link ecological principles to real-world environmental issues, and to link issues to human daily life.
This project operationalizes research in number, operation, and early algebra. It builds on the paradigm of Dynamic Geometry (the interactive and continuous manipulation of geometric shapes and constructions) with a new technological paradigm, Dynamic Number, centered on the direct manipulation of numerical representations and constructions. Using The Geometer’s Sketchpad as a starting point, KCP Technologies is developing new software tools to deepen students’ conceptions of number and early algebra in grades 2–8.
Math Pathways & Pitfalls lessons for students boost mathematics achievement for diverse students, including English Learners, English Proficient students, and Latino students. This project develops modules that increase teachers’ capacity to employ the effective and equitable principles of practice embodied by Math Pathways & Pitfalls and apply these practices to any mathematics lesson. This four-year project develops, field tests, and evaluates 10 online professional development modules.
This project provides visionary leadership to the education community by (a) identifying and analyzing the needs and opportunities for future STEM curriculum development and (b) recommending policy positions and actions by funding agencies and STEM educators regarding the development and implementation of STEM school curricula.
This project is developing and testing a prototype electronic teacher's guide for a 12-week genetics unit in the NSF-funded curriculum titled Foundation Science: Biology to determine how it impacts high school teachers' learning and practice. The electronic guide, which is based on an existing print guide, has a flexible design so that it anticipates and meets the curriculum planning and support needs of teachers with different knowledge/skills profiles.
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.
This project is revising and field testing six existing modules and developing, pilot testing, and field testing two engineering modules for required middle school science and mathematics classes: Catch Me if You Can! with a focus on seventh grade life science; and Creating Bioplastics targeting eighth grade physical science. Each module addresses an engineering design challenge of relevance to industries in the region and fosters the development of engineering habits of mind.
This project is developing and implementing a rigorous eighth grade physical science program that utilizes engineering design, LEGO™ robotics and mechanics, and a problem-based learning approach to teach mechanics, waves, and energy.
This project is a four-year, longitudinal, mixed-methods study of 12 school districts’ implementation of elementary mathematics instructional materials. It investigates the relationships among the district level of coherence of implementation, the school level of support for implementation, the school level of use of materials, and the effects on student outcomes.
This project investigates the educational value of computer technologies for learning engineering. The project engages high school students to design, build, and evaluate an energy-efficient model house with the aid of computer simulation and design tools.
The University of South Florida is hosting a conference on Research on the Enacted K-12 Mathematics Curriculum. The purpose of the conference is to explicate the theory on mathematics curriculum enactment, defining key constructs and explaining how they are expected to interact, and why, in order to facilitate the systematic accumulation of knowledge about mathematics curriculum enactment that can guide policy and practice.
This project is designing, developing, and testing an innovative approach to elementary students' learning in the critical areas of multiplicative reasoning, fractions, and proportional reasoning. The project is building on the successful El'Konin-Davydov (E-D) elementary mathematics curriculum that originated in Russia to develop a curriculum framework that can be implemented in U. S. schools. The ultimate product of the research will be a rational number learning progression consisting of carefully articulated and sequenced learning goals.
This research and development project examines the impact of the Project-Based Inquiry Science (PBIS) middle school science curriculum. The research questions explored will look into efficacy, implementation, and teacher practice. A unique feature of the study’s design is an analytic focus on the conditions needed to implement the curriculum in ways that improve student learning in light of the Framework for K-12 Science Education.
This project will develop a learning progression that characterizes how learners integrate and interrelate scientific argumentation, explanation and scientific modeling, building ever more sophisticated versions of practice over time using the three common elements of sense-making, persuading peers and developing consensus. The learning progression is constructed through students’ understanding of scientific practice as measured by their attention to generality of explanation, clarity of communication, audience understanding, evidentiary support, and mechanistic versus descriptive accounts.
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.
