Extended Book Review: Really Big Numbers, By Richard Evan Schwartz; The Boy Who Loved Math: The Improbable Life Of Paul Erdös, By Deborah Heiligman; The Short Seller, By Elissa Brent Weissman, Gizem Karaali

Pomona Faculty Publications and Research

The genre of math lit for children is not huge, but it is growing. My kid loves the early reader books by my friend and colleague Julie Glass (A Dollar for Penny (1998), The Fly On the Ceiling (2000)). I found Izolda Fotiyeva’s Math with Mom (2003) too late for my daughter but will definitely read it with my son. For a neat twist on the traditional alphabet book, I recommend The Technical Alphabet (2014) by the engineer sisters Lavanya and Melissa Jawaharlal. More recently a colleague introduced me to Laura Overdeck’s Bedtime Math series; these will soon join …

Student Evaluation Of Mathematical Explanations In An Inquiry-Based Mathematics Classroom, Ashley Burgess Hulet

Theses and Dissertations

Students do not always evaluate explanations based on the mathematics despite their teacher's effort to be the guide-on-the-side and delegate evaluation to the students. This case study examined how the use of three features of the Discourse—authority, sociomathematical norms, and classroom mathematical practices—impacted students' evaluation and contributed to students' failure to evaluate. By studying three pre-service elementary school students' evaluation methods, it was found that the students applied different types of each of the features of the Discourse and employed them at different times. The way that the features of the Discourse were used contributed to some of the difficulties …

A secondary area this study attempted to explore was the correlation between the implemented processes in the initiative and high school students’ scientific argumentative writing proficiencies. The study was conducted in a mid-western high school, population 1,088, with a select group of students in …

Naturalists’ Perspectives On The Use Of Mobile Technology During A Nature Hike, Aubin Marishka Radzewicz St. Clair

Master's Theses

Naturalists act as our link between scientific knowledge and the public’s understanding of natural history and conservation efforts. In order for them to succeed, they need access to reference materials as well as up-to-date information (Mankin, Warner, & Anderson, 1999). Incorporating mobile technology (i.e. tablets) into naturalists’ endeavors in natural history and environmental education can be used as supportive and educational tools. My project investigated how newly trained naturalists used tablet technology while leading groups of children on nature hikes. I investigated naturalists’ views on the use of mobile technology as a tool during the hikes. My research was guided …

Developing And Describing The Use And Learning Of Conceptual Models For Integer Addition And Subtraction Of Grade 5 Students, Nicole Wessman-Enzinger

Faculty Publications - College of Education

This dissertation reports the results of a teaching experiment, which explored student thinking about integer addition and subtraction. Through the lens of commognitive theory (Sfard, 2008), interpreting negative integers as secondary intuitions (Fischbein, 1987), and employing teaching experiment methodology (Steffe & Thompson, 2000), this study was a first step in developing more robust descriptions of students’ conceptual models for integer addition and subtraction. I investigated: (a) the conceptual models that students exhibited, (b) the various ways that students utilized conceptual models while learning about the addition and subtraction of integers, and (c), the ways that students’ conceptions evolved over the …

Investigating How Students Communicate Tree-Thinking, Carrie Jo Boyce

Dissertations

Learning is often an active endeavor that requires students work at building conceptual understandings of complex topics. Personal experiences, ideas, and communication all play large roles in developing knowledge of and understanding complex topics. Sometimes these experiences can promote formation of scientifically inaccurate or incomplete ideas. Representations are tools used to help individuals understand complex topics. In biology, one way that educators help people understand evolutionary histories of organisms is by using representations called phylogenetic trees. In order to understand phylogenetics trees, individuals need to understand the conventions associated with phylogenies.

My dissertation, supported by the Tree-Thinking Representational Competence and …

The Relationship Between An Affective Instructional Design, Children’S Attitudes Toward Mathematics, And Math Learning For Kindergarten-Age Children, Wendee B. White Mrs

Electronic Theses and Dissertations

This study explores the relationship between an Affective Instructional Design (AID), children’s attitudes toward math, and math learning. Participants included 15 kindergarten children at a university K-12 laboratory school located in East Tennessee. This quasi-experimental study employed a pretest-intervention (AID)-posttest design. Data, including pretest/posttest attitude surveys, and baseline and intervention non-participant video observations of math learning and math attitudes, during 13 math lessons were coded and analyzed. As hypothesized, a significant positive correlation (r = 0.936, p = 0.000) was found between attitude and math learning. Additionally significant differences were found between the baseline (pre-intervention) mean score and the final …

Reflections On Math Students’ Circles: Two Personal Stories From Colorado, Diana White, Lori Ziegelmeier

Journal of Humanistic Mathematics

Math Students’ Circles provide an opportunity for mathematicians to work in their communities to engage young students in mathematics as a human, aesthetic, and social endeavor. Sometimes referred to simply as Math Circles, these venues give mathematicians experience in introducing children to topics not typically seen in school curricula in an exciting, hands-on format. This article explores two Math Students’ Circles (MSCs) in the state of Colorado from the point of view of two pre-tenure faculty members. One participated in MSCs for four years while working on her Ph.D. in mathematics, the other started an MSC as an offshoot of …

On Similarities And Differences Between Proving And Problem Solving, Milos Savic

Journal of Humanistic Mathematics

A link between proving and problem solving has been established in the literature [5, 21]. In this paper, I discuss similarities and differences between proving and problem solving using the Multidimensional Problem-Solving Framework created by Carlson and Bloom [2] with Livescribepen data from a previous study [13]. I focus on two participants’ proving processes: Dr. G, a topologist, and L, a mathematics graduate student. Many similarities between the framework and the proving processes of Dr. G and L were revealed, but there were also some differences. In addition, there were some distinct differences between the proving actions of the …

Attitudes And Experiences In Liberal Arts Mathematics, Jennifer Clinkenbeard

Journal of Humanistic Mathematics

For many university students, the last formal experience in a mathematics classroom is a single semester “general education” mathematics class. Traditionally, students in this type of class often hold negative attitudes towards mathematics. Here I study a sample of students from this population (49 students at a large, urban, comprehensive public university enrolled in a “math for liberal arts majors” course) to research whether a positive experience in a freshman-level general education mathematics course correlates with a positive change in the students’ attitude towards mathematics in general. I also explore which specific aspects of such a course contribute most to …

E-Brock Bugs©: An Epistemic Mathematics Computer Game, Laura Broley, Chantal Buteau, Eric Muller

Journal of Humanistic Mathematics

Devlin in [7] argues that video games are an ideal medium for the teaching and learning of mathematics, though he points out that very few ’good’ mathematics video games exist. Building on a probabilistic board game developed in the 1980s, we created a mathematics computer game, E-Brock Bugs. The design of the game carefully follows Devlin’s principles of a good mathematics video game, including a well-developed storyline, the selection of an in-game avatar, and an environment where mathematics arises in a natural and meaningful way. As a result, we argue that E-Brock Bugs is an epistemic computer game [1]; …

Ninth Grade Student Responses To Authentic Science Instruction, Michael Steven Ellison

Dissertations and Theses

This mixed methods case study documents an effort to implement authentic science and engineering instruction in one teacher's ninth grade science classrooms in a science-focused public school. The research framework and methodology is a derivative of work developed and reported by Newmann and others (Newmann & Associates, 1996). Based on a working definition of authenticity, data were collected for eight months on the authenticity in the experienced teacher's pedagogy and in student performance. Authenticity was defined as the degree to which a classroom lesson, an assessment task, or an example of student performance demonstrates construction of knowledge through use of …

Promoting Numeracy In An Online College Algebra Course Through Projects And Discussions, Samuel L. Tunstall, Michael J. Bossé

Numeracy

This research stems from efforts to infuse quantitative literacy (QL) in an online version of college algebra. College algebra fulfills a QL requirement at many universities, and it is a terminal course for most who take it. In light of the course’s traditional content and teaching methods, students often leave with little gained in QL. An online platform provides a unique means of engaging students in quantitative discussions and research, yet little research exists on online courses in the context of QL. The course studied included weekly news discussions as well as “messy” projects requiring data analysis. Students in online …

Implementing Quantitative Literacy At Southwestern Community College, North Carolina, Vicki Todd, John Wagaman

Numeracy

There is a time when articulation agreements between universities and community colleges come to an end. When this happened in North Carolina, there was great hope that not only would the mathematics classes that were offered in the North Carolina Community College System be revamped with respect to overlapping content, but also that mathematics classes would be developed that have a clear connection between what is seen in the world and what is taught in the classroom especially for non-STEM (science, technology, engineering, and mathematics-related studies) students. This paper describes how Southwestern Community College (SCC) implemented a quantitative literacy class …

The Math You Need, When You Need It (Tmyn): Leveling The Playing Field, Jennifer M. Wenner, Eric M. D. Baer

Numeracy

The Math You Need, When You Need It (TMYN) is a set of online tutorials designed to help students develop and review mathematical skills that are applied in undergraduate geoscience courses. We present results of a three-year study of more than 4000 students in 106 geoscience courses at a variety of post-secondary schools who were assigned TMYN tutorials as supplemental mathematics instruction. Changes in student scores from pre- to post-test suggest that the support provided by programs such as TMYN can begin to reduce the gap between mathematically well-prepared and underprepared students; in essence, TMYN levels the quantitative playing field …

Quantitative Reasoning In Environmental Science: Rasch Measurement To Support Qr Assessment, Robert L. Mayes, Kent Rittschof, Jennifer H. Forrester, Jennifer D. Schuttlefield Christus, Lisa Watson, Franziska Peterson

Numeracy

The ability of middle and high school students to reason quantitatively within the context of environmental science was investigated. A quantitative reasoning (QR) learning progression, with associated QR assessments in the content areas of biodiversity, water, and carbon, was developed based on three QR progress variables: quantification act, quantitative interpretation, and quantitative modeling. Diagnostic instruments were developed specifically for the progress variable quantitative interpretation (QI), each consisting of 96 Likert-scale items. Each content version of the instrument focused on three scale levels (macro scale, micro scale, and landscape scale) and four elements of QI identified in prior research (trend, translation, …
