Persistence of Teacher Change in Rural Schools: Assessing the Short- and Long-term Impact of Professional Development on K-2 Science Instruction
This research study is examining the persistence of improved teacher skills achieved during the K-2 Science & Technology Assistance for Rural Teachers and Small Districts project (K-2 STARTS). K-2 STARTS provided four years of professional development to teachers in 16 rural school districts with high populations of traditionally underserved students. Project data indicates that the project increased teacher content knowledge, pedagogical content knowledge, abilities to integrate science and literacy and to use research-based instructional strategies.
Constructing and Critiquing Arguments in Middle School Science Classrooms: Supporting Teachers with Multimedia Educative Curriculum Materials
This project is developing Earth and Space Science multimedia educative curriculum materials (MECMs) and a system to facilitate teachers' learning and beliefs of scientific argumentation. The project is investigating the impact of the MECMs on teachers' beliefs about scientific argumentation and their related pedagogical content knowledge. The overarching research question focuses on how can multimedia educative curriculum materials provide support to middle school science teachers in implementing standards for constructing and critiquing arguments.
Further Development and Testing of the Target Inquiry Model for Middle and High School Science Teacher Professional Development (Collaborative Research: Yezierski)
This project scales and further tests the Target Inquiry professional development model. The model involves teachers in three core experiences: 1) a research experience for teachers, 2) materials adaptation, and 3) an action research project. The original program was implemented with high school chemistry teachers, and was shown to result in significant increases, with large effect sizes, in teachers' understanding of science inquiry and quality of instruction, and in science achievement of those teachers' students.
CAREER: Noticing and Capitalizing on Important Mathematical Moments in Instruction
This project investigates the outcomes of a teacher education model designed to foster prospective mathematics teachers' abilities to notice and capitalize on important mathematical moments in instruction. The project engages prospective teachers in research-like analysis of unedited teacher-perspective classroom video early in their teacher education coursework in order to help them learn to identify, assess the mathematical potential of, and respond to important student ideas and insights that arise during instruction.
Expanding and Sustaining Understanding Evolution
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.
Evaluating the Developing Mathematical Ideas Professional Development Program: Researching its Impact on Teaching and Student Learning
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.
Virtual Learning Communities: An Online Professional Development Resource for STEM Teachers
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.
Across the Sciences: Multidisciplinary Learning for Teachers through Multimedia
This project will conduct a professional development series to improve the content knowledge of science teachers. "Across the Sciences," a ten-unit series requiring approximately 145 hours to complete, will better qualify 9th and 10th grade science teachers to teach multidisciplinary science courses. Teachers prepared in one science discipline will benefit from opportunities to increase and deepen their interdisciplinary science content knowledge and their understanding of student needs associated with learning science.
Mapping Developmental Trajectories of Students' Conceptions of Integers
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.
Math Snacks: Addressing Gaps in Conceptual Mathematics Understanding with Innovative Media
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.
