Publication | An electronic teacher guide (eTG) was developed to determine whether a digital guide could better support teachers in implementing an inquiry-based curriculum and in enhancing their practice. Developed as a proof-of-concept exemplar, features of…
Publication | This exploratory study examines how a foundational scheme of unit fractions (1/n) may evolve through the mathematical activity of two fifth grade girls.
Publication | The logic underlying inclusive STEM high schools (ISHSs) posits that requiring all students to take advanced college preparatory STEM courses while providing student-centered, reform-oriented instruction, ample student supports, and real-world…
Publication | While Science, Technology, Engineering, and Math (STEM) fields have increased in importance over the past decade, minorities have remained traditionally underrepresented in these fields. In this study we seek to better understand some of the…
Publication | This study investigates the models of elementary content specialization (ECS) in elementary mathematics and science and the affordances and constraints related to ECS—both generally and in relation to specific models.
Publication | This study reports data gathered from over 500 doctoral graduates in mathematics education from 23 institutions in the USA from 1997 to 2014 as they self-assessed their research preparation during their doctoral program.
Tool | Whether engaging students in place-based learning, designing/implementing more inclusive curricula or pedagogy, or helping teachers develop their capacity to teach increasingly diverse groups of learners, many DR K-12 projects seek to broaden…
Product for Educators | The Journey to El Yunque curriculum introduces students to disturbance ecology, with a focus on both ecosystem resilience and ecosystem change. Each page is beautifully illustrated by Puerto Rican artist Robert Casilla to connect…
Publication | Providing opportunities for learning through professional development requires the examination of facilitation of sessions with teachers. This study investigates facilitation of professional development to promote teacher learning when using…
Publication | Elementary school teachers’ perceptions of school resources (i.e., material, human, and social) for teaching science to diverse student groups were examined across three school districts from one state. As part of a 3-year curricular and…
Publication | This study investigates facilitation of professional development to promote teacher learning when using animations and videos in a study group with five teachers.
Publication | This article highlights the production of doctorates in mathematics education for the past fifty years.
Publication | In this exploratory study, we present typologies that represent two primary challenges teachers faced in developing coherent conceptual storylines in their lesson design, and examine the extent to which professional development enhanced their…
Publication | While past research has mainly focused on absolute cognitive ability levels in math and verbal domains, the current study tested whether relative cognitive strengths and interests in math, science, and verbal domains in high school were more…
Publication | The state of Florida has taken an unprecedented approach to teacher professional development in its Race to the Top
(RTTT) Program application by proposing to promote an international innovation that originates in Japan, “lesson study,” as
a…
Publication | The importance of valuing student ideas in science education stands on firm empirical, theoretical, and moral grounds. However, the reasons for which one might value student ideas are often not explicitly distinguished, even if implicit…
Publication | In this article, we describe the experiences of three Elementary Mathematics Specialists (EMS) who were part of a larger project investigating the impact of EMS certification and assignment (self-contained or “departmentalized”) on teaching…
Publication | This commentary focuses on doctoral programs and doctoral preparation in mathematics education.
Publication | Current intervention research in special education focuses on children's responsiveness to teacher modeled strategies and not conceptual development within children's thinking. As a result, there is a need for research that provides a…
Publication | The study examined patterns of change in primary school teachers’ inquiry practices, inquiry beliefs and physical science content knowledge during both years as well as the effects of school-level and individual-level factors on these changes in…
Publication | This report summarizes the 2013, 2014, and 2015 findings from a longitudinal survey of district professional development coordinators across the state of Florida. The results are presented with six sections: 1) District policy and practice, 2)…
Publication | From a social semiotic perspective, students’ use of language is fundamental to mathematical meaning making. We applied thematic analysis to examine students’ use of geometric and contextual ideas while solving a geometry problem that required…
Publication | This brief article provides an overview of how to use the SageModeler systems modeling tool with an ocean acidification model as an example.
