Mathematical modeling is a critical component of the current K-12 mathematics, science, and technology and engineering (T&E) educational standards in the United States. However, mathematical modeling is often overlooked or underemphasized in integrative STEM lessons. This could be attributed to teachers' limited content and pedagogical…

This inquiry examined the pedagogical practices in mathematics of elementary teachers (N = 27) who had been identified as experienced and successful and were working in an urban school district with underserved student populations. Also investigated were relationships between their instructional practices and other elements of proficient teaching…

The Teacher Academy in the Natural Sciences (TANS) provided middle school (U.S. Grades 6-8) teachers (N = 81) with intensive professional development (PD) in chemistry, geosciences, and physics, with teachers enrolled in one scientific discipline per year. Because some teachers were retained and rotated into different disciplines, the TANS program…

Despite agreement among teacher educators, scholars, and policymakers on the importance of teachers' subject matter knowledge (SMK), existing models provide limited information about the nature of this foundational component of teacher knowledge. The common assumption is that teachers need to know more about the science subject matter than their…

In the transition to middle school, and during the middle school years, students' motivation for mathematics tends to decline from what it was during elementary school. Formative assessment strategies in mathematics can help support motivation by building confidence for challenging tasks. In this study, the authors developed and piloted a…

This study adds to our understanding of science and mathematics teacher leadership in rural schools. Through In Vivo and Concept coding of teacher interviews, we investigated 20 secondary science and mathematics teachers' perceptions of rural teacher leadership during their participation in a three-year professional development program. As the…

Numerous national initiatives call for interdisciplinary mathematics and science education, but few empirical studies have examined practical considerations for integrated instruction in high school settings. The purpose of this qualitative study was twofold. First, the study sought to describe how and to what extent teachers integrate mathematics…

Project-based science (PBS) aligns with national standards that assert children should learn science by actively engaging in the practices of science. Understanding and implementing PBS requires a shift in teaching practices away from one that covers primarily content to one that prompts children to conduct investigations. A common challenge to…

If teachers make few connections among multiple representations of division, supporting students in using representations to develop operation sense demanded by national standards will not occur. Studies have investigated how prospective and practicing teachers use representations to develop knowledge of fraction division. However, few studies…

We describe and analyze a professional development (PD) model that involved a partnership among science, mathematics and education university faculty, science and mathematics coordinators, and middle school administrators, teachers, and students. The overarching project goal involved the implementation of interdisciplinary STEM Design Challenges…

Reforms in mathematics education call for K-12 teachers to employ standards-based pedagogies, which embody the National Council for Teachers of Mathematics' principles and standards. In order to effectively support teachers' implementation of standards-based curricula, professional development must be provided that meets teachers' needs. The…

This study highlights the factors that contribute to excellence in urban science teaching as pinpointed by five urban African-American science teachers who have taught successfully in the urban system for over 10 years. These teachers shared their experiences and reflections on the qualities that contributed to their success and persistence as…

Student initiatives play an important role in inquiry-based science with all students, including English language learning (ELL) students. This study examined initiatives that elementary students made as they participated in an intervention to promote science learning and English language development over a three-year period. In addition, the…
