The Problem-Solving Process In A Mathematics Classroom, Enrique Ortiz

Transformations

Problem solving provides a working framework to apply mathematics, and well chosen mathematics problems provide students with the opportunity to solidify and extend what they know, and can stimulate students’ mathematics learning (NCTM, 2001). Using this framework, students may utilize ways to learn mathematics concepts and skills that are rich with meaning and connections, and pre- and in-service teachers may implement teaching and assessment procedures to establish teaching and assessment environments.

Function Concept: Learning From History, Ruthmae Sears, Dung Tran, Seoung Woo Lee, Amanda Thomas

Transformations

The importance of functions in school mathematics has grown tremendously within the past century. Functions have progressed from being scantly represented in school mathematics to being a core mathematical topic. C.B. Boyer (1946) acknowledged “The development of the function concept has revolutionized mathematics in much the same way as did the nearly simultaneous rise of non-Euclidean geometry. It has transformed mathematics from a pure natural science- the queen of the sciences- into something vastly large. It has established mathematics as the basis of all rigorous thinking – the logic of all possible relations” (Markovits, Eylor, & Bruckheimer, 1986, p. 18). …

What Does Motivated Mean? Re-Presenting Learning, Technology, And Motivation In Middle Schools Via New Ethnographic Writing, Justin Olmanson

Department of Teaching, Learning, and Teacher Education: Faculty Publications

This article offers a critique of the way middle schoolers are often positioned as generalizable objects that can be acted upon to produce measurable increases in motivation and learning. The critique invites a reconsideration and cultural analysis of some of the dominant discourses and perceptions of technology, young adolescence, and the study of motivation. The use of New Ethnographic Writing—a method that performs a cultural critique via extended scenes—connects to the roles and status of motivation, technology, and educational research methods deployed within public schools. Coupled with weak theory, this approach offers a way to understand young adolescents as navigating …

University of Nebraska State Museum: Mammalogy Papers

This is the authors' collective attempt to provide an encomium (an honest song of praise) for Clyde Jones. After some urging from the editors of this volume, the authors conspired to share some memories of Clyde.

Editors’ note: Due to various factors, this encomium was submitted too late to be included in the published memorial volume. However, in consideration of the relationship of the authors to Clyde Jones, we agreed to make this encomium available via electronic format as a supplement to the printed volume.

From Chilly Climate To Warm Reception: Experiences And Good Practices For Supporting Lgbtq Students In Stem, Carolyn S. Brinkworth

CGU Theses & Dissertations

Lesbian, gay, bisexual, transgender, and queer/questioning students (LGBTQ) face unique challenges during their university or college careers, and while society has generally become more accepting of sexual and gender minorities (SGM) over the past decade, students still often face chilly or outright hostile campus climates, as well as institutional and departmental policies and practices that create barriers to their learning and feeling of belonging in their classrooms and on their campuses. Research suggests that these issues are particularly pervasive in the disciplines of Science, Technology, Engineering and Mathematics (STEM), and there is some evidence to suggest that LGBTQ individuals are …

Transformative Models In K-12 Education: The Impact Of A Blended Universal Design For Learning Intervention, Kai Monet Mathews

Dissertations

Accountability measures, by way of standardized curriculum and assessments, have played a large part in the attempt to ensure that students from all backgrounds receive equal access to quality education. However, the inherent disadvantage of a standardized system is the implied assumption that all students come in with the same knowledge, learn at the same pace, and learn the same way. In the wake of an increasingly diverse K-12 population, educational researchers, learning theorists, and practitioners agree that the concept of the average student is, in fact, a myth. Students come to school with different needs, norms, interests, cultural behavior, …

Ecosystem Disruption & Climate Change

Information taken from: Dirzo, R. et al (2014). Defaunation in the Anthropocene. Science, 345(401).

Scientists estimate, conservatively, that there are 5 to 9 million different animal species on the planet. But that number is continually changing, and unfortunately, dropping, as we are likely losing 11,000- 58,000 species annually, and evidence suggests that on average, there has been a decline of about 28% in terms of numbers of individuals within a species over the last four decades. Both of these statistics are vitally important. The critical nature of the first is perhaps more obvious, as total loss of a species is …

Have Gender Gaps In Math Closed? Achievement, Teacher Perceptions, And Learning Behaviors Across Two Ecls-K Cohorts, Joseph R. Cimpian, Sarah T. Lubienski, Jennifer D. Timmer, Martha B. Makowski, Emily K. Miller

Mathematics Faculty Publications

Studies using data from the Early Childhood Longitudinal Study–Kindergarten Class of 1998–1999 (ECLS-K:1999) revealed gender gaps in mathematics achievement and teacher perceptions. However, recent evidence suggests that gender gaps have closed on state tests, raising the question of whether such gaps are absent in the ECLS-K:2011 cohort. Extending earlier analyses, this study compares the two ECLS-K cohorts, exploring gaps throughout the achievement distribution and examining whether learning behaviors might differentially explain gaps more at the bottom than the top of the distribution. Overall, this study reveals remarkable consistency across both ECLS-K cohorts, with the gender gap developing early among high …

A Multiple Case Study Examining How Third-Grade Students Who Struggle In Mathematics Make Sense Of Fraction Concepts, Rebecca Gault

Electronic Theses and Dissertations

A qualitative multiple case study was conducted to reveal the sense-making processes third-grade students who struggle in mathematics used to build an understanding of fraction concepts. Purposive sampling identified three participants who were struggling in a local school's third grade mathematics classes. This research describes how these participants made sense of fraction concepts through their strengths and struggles while engaged in 15 small-group intervention sessions. Vygotsky's (1934/1986/2012) theory that children's optimal learning is supported by teacher-student interactions was used as an interpretive framework. Tasks were developed over the course of the intervention sessions with consideration of a model developed by …
