Roman Domination In Complementary Prisms, Alawi I. Alhashim 2017 East Tennessee State University

Roman Domination In Complementary Prisms, Alawi I. Alhashim

Electronic Theses and Dissertations

The complementary prism GG of a graph G is formed from the disjoint union of G and its complement G by adding the edges of a perfect match- ing between the corresponding vertices of G and G. A Roman dominating function on a graph G = (V,E) is a labeling f : V(G) → {0,1,2} such that every vertex with label 0 is adjacent to a vertex with label 2. The Roman domination number γR(G) of G is the minimum f(V ) = Σv∈V f(v) over all such functions of G. We study the Roman domination number ...

“Science Is Not My Thing”: Exploring Deaf Non-Science Majors’ Science Identities, Cara L. Gormally, Amber Marchut 2017 Gallaudet University

“Science Is Not My Thing”: Exploring Deaf Non-Science Majors’ Science Identities, Cara L. Gormally, Amber Marchut

Journal of Science Education for Students with Disabilities

Students who are deaf and hard-of-hearing are underrepresented in science majors, yet we know little about why. Students from other underrepresented groups in science—women and people of color—tend to highly value altruistic or communal career goals, while perceiving science as uncommunal. Research suggests that holding stereotypical conceptions about scientists and perceptions of science as uncommunal may strongly hinder recruitment into science majors. This study sought to explore the science identities of students who are deaf, hard-of-hearing, and hearing signers. The study focused on non-science majors in bilingual (American Sign Language and written English) biology laboratory courses. This study ...


Disciplinary Differences In Out-Of-School High School Science Experiences And Influence On Students’ Engineering Choices, Allison Godwin, Gerhard Sonnert, Philip M. Sadler 2017 Purdue University

Disciplinary Differences In Out-Of-School High School Science Experiences And Influence On Students’ Engineering Choices, Allison Godwin, Gerhard Sonnert, Philip M. Sadler

Journal of Pre-College Engineering Education Research (J-PEER)

Participation from a variety of students is important to the long-term growth of the engineering field. Much of the research on engineering recruitment or career choice has focused on engineering as a whole, even though engineering disciplines are varied in student participation and focus. This work examines how students’ out-of-school interests and experiences in high school predict the likelihood of choosing a career in a particular engineering discipline. Out-of-school experiences offer more unstructured ways for students to meaningfully engage with science and engineering outside of the confines of the classroom. These experiences offer opportunities to spark particular science interests not ...


The Relationship Between Project-Based Learning And Rigor In Stem-Focused High Schools, Julie Edmunds, Nina Arshavsky, Elizabeth Glennie, Karen Charles, Olivia Rice 2017 SERVE Center at University of North Carolina at Greensboro

The Relationship Between Project-Based Learning And Rigor In Stem-Focused High Schools, Julie Edmunds, Nina Arshavsky, Elizabeth Glennie, Karen Charles, Olivia Rice

Interdisciplinary Journal of Problem-Based Learning

Project-based learning (PjBL) is an approach often favored in STEM classrooms, yet some studies have shown that teachers struggle to implement it with academic rigor. This paper explores the relationship between PjBL and rigor in the classrooms of ten STEM-oriented high schools. Utilizing three different data sources reflecting three different perceptions—student surveys, teacher logs, and classroom observations—the study examines the extent to which PjBL and rigor co-occur. Across all three measures, the results show that use of PjBL is associated with higher levels of rigor. However, the study also shows that academic rigor can be present in the ...


Parts Of The Whole: Error Estimation For Science Students, Dorothy Wallace 2017 Dartmouth College

Parts Of The Whole: Error Estimation For Science Students, Dorothy Wallace

Numeracy

It is important for science students to understand not only how to estimate error sizes in measurement data, but also to see how these errors contribute to errors in conclusions they may make about the data. Relatively small errors in measurement, errors in assumptions, and roundoff errors in computation may result in large error bounds on computed quantities of interest. In this column, we look closely at a standard method for measuring the volume of cancer tumor xenografts to see how small errors in each of these three factors may contribute to relatively large observed errors in recorded tumor volumes.


Connecting Numbers With Emotion: Review Of Numbers And Nerves: Information, Emotion, And Meaning In A World Of Data By Scott Slovic And Paul Slovic (2015), Samuel L. Tunstall 2017 Michigan State University

Connecting Numbers With Emotion: Review Of Numbers And Nerves: Information, Emotion, And Meaning In A World Of Data By Scott Slovic And Paul Slovic (2015), Samuel L. Tunstall

Numeracy

Scott Slovic and Paul Slovic (Eds.). Numbers and Nerves: Information, Emotion, and Meaning in a World of Data (Corvallis, OR: Oregon State University Press, 2015). 272 pp. ISBN 978-0-87071-776-5.

It is common to view quantitative literacy as reasoning with respect to numbers. In Numbers and Nerves, the contributors to the volume make clear that we should attend not only to how students consciously reason with numbers, but also how our innate biases influence our actions when faced with numbers. Beginning with the concepts of psychic numbing, and then psuedoinefficacy, the contributors to the volume examine how our behaviors when faced ...

The handbook contains information on leadership and management, how to maintain community interactions, managing staffing ...


Quantitative Literacy For The Future Flourishing Of Our Students: A Guiding Aim For Mathematics Education, Samuel L. Tunstall 2017 Michigan State University

Quantitative Literacy For The Future Flourishing Of Our Students: A Guiding Aim For Mathematics Education, Samuel L. Tunstall

Numeracy

In this essay, I examine the extent to which mathematics education and education for quantitative literacy support students’ present and future flourishing, a concept that entails realizing objective goods in a life lived from the inside. This perspective requires disentangling philosophical assumptions about the aims of mathematics education, which—in the context of flourishing—I take to be a hybrid of those that have informed curricular discussions over the past two centuries. In the process, I problematize ("make strange") many of the common reasons given for students learning mathematics, including: learning it for one’s career, for one’s logical ...


A Twenty-Year Look At “Computational Geology,” An Evolving, In-Discipline Course In Quantitative Literacy At The University Of South Florida, Victor J. Ricchezza, H. L. Vacher 2017 University of South Florida

A Twenty-Year Look At “Computational Geology,” An Evolving, In-Discipline Course In Quantitative Literacy At The University Of South Florida, Victor J. Ricchezza, H. L. Vacher

Numeracy

Since 1996, the Geology (GLY) program at the USF has offered “Computational Geology” as part of its commitment to prepare undergraduate majors for the quantitative aspects of their field. The course focuses on geological-mathematical problem solving. Over its twenty years, the course has evolved from a GATC (geometry-algebra-trigonometry-calculus) in-discipline capstone to a quantitative literacy (QL) course taught within a natural science major. With the formation of the new School of Geosciences in 2013, the merging departments re-examined their various curricular programs. An online survey of the Geology Alumni Society found that “express quantitative evidence in support of an argument” was ...


The Quantitative Reasoning For College Science (Quarcs) Assessment 2: Demographic, Academic And Attitudinal Variables As Predictors Of Quantitative Ability, Katherine Follette, Sanlyn Buxner, Erin Dokter, Donald McCarthy, Beau Vezino, Laci Brock, Edward Prather 2017 Stanford University

The Quantitative Reasoning For College Science (Quarcs) Assessment 2: Demographic, Academic And Attitudinal Variables As Predictors Of Quantitative Ability, Katherine Follette, Sanlyn Buxner, Erin Dokter, Donald Mccarthy, Beau Vezino, Laci Brock, Edward Prather

Numeracy

In this article, we explore the ability of demographic and attitudinal variables to predict student scores on the Quantitative Reasoning for College Science (QuaRCS) Assessment. Variables measured by the assessment include: students' academic choices and plans, attitudes and perceptions regarding mathematics, self-reported effort level, and basic demographics such as age, race/ethnicity, gender and disability status. As in previously published numeracy studies, we find significant score deviations according to gender, race/ethnicity, and disability status; however, the effect size of these correlations pale in comparison to the effect size of affective/attitudinal variables on QuaRCS score. A large number of ...

Providing Open-Access Know How For Directors Of Quantitative And Mathematics Support Centers, Michael Schuckers, Mary B. O'Neill, Grace Coulombe

Numeracy

The purpose of this editorial is to introduce the quantitative literacy community to the newly published A Handbook for Directors of Quantitative and Mathematics Centers. QMaSCs (pronounced “Q-masks”) can be broadly defined as centers that have supporting students in quantitative fields of study as part of their mission. Some focus only on calculus or mathematics; others concentrate on numeracy or quantitative literacy, and some do all of that. A QMaSC may be embedded in a mathematics department, or part of a learning commons, or a stand-alone center. There are hundreds of these centers in the U.S. The new handbook ...
