Definitions And Meaning For Future Teachers In Spatial Measurement: Length, Area, And Volume, Eryn M. Stehr Maher, Jia He

Proceedings of the Interdisciplinary STEM Teaching & Learning Conference (Archived)

U.S. students have consistently demonstrated poor performance in spatial reasoning in standardized testing (e.g., National Assessment of Educational Progress). One possible reason is students' lack of conceptual understanding of measurement concepts (length, area, volume, capacity). This paper describes different ways that mathematics textbooks written for future elementary teachers define meanings of measurement concepts, especially the meaning of measure, area, and the measurement process (generally and for area). We base the analysis of definitions and construction of complete definitions using several definitions of each concept from mathematics textbooks written for future elementary teachers (e.g., Beckmann, 2012; Sowder, Sowder, & Nickerson, 2010). …

Equilibria And Synchrotron Stability In Two Energy Storage Rings, B. Dhital, Jean R. Delayen, Y. S. Derbenev, D. Douglas, Geoffrey A. Krafft, F. Lin, B. Morozov, Y. Zhang

Physics Faculty Publications

In a dual energy storage ring, the electron beam passes through two loops at markedly different energies E_{L}, and E_{H}, i.e., energies for low energy loop and high energy loop respectively. These loops use a common beamline where a superconducting linac at first accelerates the beam from EL to EH and then decelerates the beam from EH to EL in the next pass. There are two basic solutions to the equilibrium problems possible, i.e., ’Storage Ring’ (SR) equilibrium and ’Energy Recovery Linac’ (ERL) equilibrium. SR equilibrium mode more resembles the usual single loop storage ring with strong synchrotron motion and …

Performing Embodied Translations: Decolonizing Methodologies Of Knowing And Being, Beaudelaine Pierre, Naimah Petigny, Richa Nagar, Sima Shakhsari

Study of Women, Gender, & Sexuality: Faculty Publications

This performance and transcript emerge from a collaborative journey that grapples with what it might mean to agitate dominant pedagogical and methodological conventions of Eurocentric Anglophone academia. Together, we perform an argument and a search: for multiple entry points into decolonizing feminisms; for multiple modes of knowing and being that can interrupt and challenge the epistemes that are rooted in thoughts and practices of colonialism and coloniality; for interrogating the dominant politics of citation that often operate in academic practices in disembodied ways. We search for a politics of knowing that is firmly rooted in relationalities where power and authoritycan …

Reading Perceptions Of Hispanic English Language Learner Families In New York City, Ligoria Berkeley-Cummins

Walden Dissertations and Doctoral Studies

Historically, Hispanic English language learners (ELLs) in the United States have had low reading achievement and low high school graduation and college entry rates, which has limited their employment opportunities. Although research indicates parental involvement is important to reading success, little is known about Hispanic ELL parents' perspectives on their children's reading development. The purpose of this basic qualitative study was to understand how parental involvement in 3rd grade Hispanic ELLs' reading development, as perceived by their families, may contribute to these students' reading proficiency. The framework for this study was Hedegaard's model of children's learning and development. The participants …
