Second-Year Pre-Service Teachers’ Responses To Proportional Reasoning Test Items, Sharyn Livy, Sandra Herbert

Australian Journal of Teacher Education

A recent international study of pre-service teachers identified that proportional reasoning was problematic for pre-service teachers. Proportional reasoning is an important topic in the middle years of schooling and therefore it is critical that teachers understand this topic and can rely on their Mathematical Content Knowledge (MCK) when teaching. The focus of this paper is second-year Australian primary pre-service teachers’ MCK of real number items related to ratio, rate, proportion and proportional reasoning. This paper reports on strengths and weakness of pre-service teachers’ MCK when responding to test items; including a method suitable for analysing responses to five items and …

On Closed Subsets Of Non-Commutative Association Schemes Of Rank 6, Jose Vera

Theses and Dissertations - UTB/UTPA

The notion of an association scheme is a generalization of the concept of a group. In fact, the so-called thin association schemes correspond in a well-understood way to groups. In this thesis, we look at the structure of non-commutative association schemes of rank 6. We will show that a non-normal closed subset of a noncommutative association scheme of rank 6, must have rank 2. The so-called Coxeter schemes of rank 6 which we present in Section 4 provide examples of association schemes of rank 6 with non-normal closed subsets of rank 2. It is shown that normal closed subsets of …

Exploring Community Colleges In The Stem Education Landscape : Development Of Stem College Major Choice Model, Colleen Evans

Seton Hall University Dissertations and Theses (ETDs)

Community colleges are becoming increasingly relevant as an entrance point into postsecondary education for potential science, technology, engineering, and mathematics (STEM) majors. These institutions are also an important education pathway for women and racial/ethnic minorities who are currently underrepresented in the STEM workforce. The purpose of this study is to understand how student demographics, high school, and college experiences influence the entrance of community college students to the STEM college majors. Data from the Education Longitudinal Study of 2002 (ELS: 2002) were used for the study. Students included in the study began their postsecondary education at community colleges. Descriptive and …

Textbooks, Teachers, And Middle School Mathematics Student Achievement, Susan R. Monaghan

Dissertations (1934 -)

The purpose of this study was to extend the research on textbook effectiveness to a situated investigation of a single large urban school district in which middle schools were given a choice in selecting from three textbooks for mathematics instruction: a reform textbook, a commercially produced textbook developed in response to mathematics standards, and a traditional textbook. Its genesis is rooted in the efforts in the mathematics education community to investigate the interaction of teachers and mathematics curriculum materials, but in light of the shift to an accountability policy climate in public education. In particular, this study sought to determine …

The Hidden Stem Economy: The Surprising Diversity Of Jobs Requiring Science, Technology, Engineering, And Math Knowledge, Jonathan Rothwell

Brookings Scholar Lecture Series

Policy and businesses leaders have argued that there is a shortage of highly educated workers in professional occupations related to science, technology, engineering, and math (STEM). Critics have countered that Ph.D scientists often face a difficult academic labor market and do not necessarily earn higher wages than other professionals. Yet, both sides of the STEM debate have been relying on an ill-defined definition of STEM work. Using a detailed survey of worker knowledge requirements, this research project redefines STEM jobs based on the level of knowledge required in STEM fields to perform occupations. The results uncover two facts previously unrecognized …

Traveling Waves, Keith Rudd, Dr. Jeffery Humpherys

Traveling waves are, mathematically speaking, partial differential equations which can be expresses as U(x-ct), where x is the spatial variable, t is time, and c is the speed of the wave. Traveling waves have applications in fluid dynamics, optics, and many other areas.

Foundations Of Tropical Geometry Classification Of Polynomials, Nathan Manwaring, Dr. Tyler Jarvis

Journal of Undergraduate Research

Tropical Mathematics is a relatively new field of mathematics that is getting a lot of attention recently. It is applicable in the field of Combinatorics as well as Phylogenetics, and more uses are being found each day. Our goal was to find a way to classify Tropical Polynomials so that they may be better understood and ultimately bridge the gap between different applications and discoveries in Tropical Mathematics.

The Effect Of A Long-Term Professional Development Course In Standards-Based Mathematics On The Attitudes And Practices Of Inservice Teachers, Destiny Turner, Dr. Candice Ridlon

Journal of Undergraduate Research

In 2000, the National Council of Teachers of Mathematics (NCTM) developed a set of principles and standards to guide mathematics teaching in grades K-12. These principles outline pedagogy that encourages students to discover and understand math on a conceptual level. These monumental standards are widely recognized, but unfortunately, are not as widely implemented in actual classrooms. Most often, this problem is addressed through short-term professional development workshops.

Factorization Of Tropical Polynomials, Nathan Grigg, Dr. Tyler Jarvis

Journal of Undergraduate Research

Tropical algebra, also called “min-plus” or “max-plus” algebra, is a relatively new topic in mathematics that has recently caught the interest of algebraic geometers, computer scientists, combinatorists, and other mathematicians. According to Andreas Gathmann , tropical algebra was pioneered by mathematician and computer scientist Imre Simon in the 1980s but did not receive widespread attention until a few years ago. Interestingly, the title “tropical algebra” is nothing more than a reference to Simon’s home country—Brazil.

Book Review: Encyclopedia Of Mathematics And Society, Gizem Karaali

Pomona Faculty Publications and Research

The Encyclopedia of Mathematics and Society is an impressive achievement of collective effort and serious thought, an amazing collection of delightful, unexpected essays, a sourcebook for students and teachers alike. The experience of reading the EMS was, for this encyclopedia enthusiast, enlightening and enjoyable.

If any librarians out there are still wondering, let me be clear: I strongly recommend this encyclopedia. For individuals, the expense might well be an initial turn-off; keeping in mind that the hard copy books come with online access to the same content might alleviate some of the pain.

As for me? I expect to enjoy …

The Effect Of Manipulatives On Achievement Scores In The Middle School Mathematics Class, Elaine D. Doias

Dissertations

When applied to mathematics education, manipulatives help students to visualize mathematical concepts and apply them to everyday situations. Interest in mathematics instruction has increased dramatically over the past two decades with the introduction of virtual manipulatives, as opposed to the concrete manipulatives that have been employed for centuries. This quasi-experimental study proposed to explain the relationship between concrete and virtual manipulatives when used in a seventh-grade mathematics classroom. Using students’ mathematics composite scores on standardized and teacher-created assessments, it compared the effectiveness of using concrete manipulatives alone versus using a combination of concrete and virtual manipulatives. The foundational theory of …

Number Of Courses, Content Of Coursework, And Prior Achievement As Related To Ethnic Achievement Gaps In Mathematics, Ernest C. Davenport Jr., Mark L. Davison, Yi-Chen Wu, Se-Kang Kim, Haijiang Kuang, Nohoon Kwak, Chi-Keung Chan, Alicia Ayodele

Journal of Educational Leadership in Action

This study utilized base-year and second follow-up data from the National Educational Longitudinal Study of 1988 to investigate the relationship between eighth-grade math achievement, mathematics course-taking in high school, and twelfth-grade math achievement. Results suggested the following: 1) Type of coursework can be quantified. 2) Type of coursework was more predictive of achievement than amount. 3) There were substantial ethnic achievement differences prior to high school. 4) Number of courses, type of courses, and prior achievement were not equally predictive of twelfth-grade mathematics achievement across ethnic groups. 5) Prior achievement did not equally predict course-taking over ethnic groups in amount …

The Fitzroy Valley Numeracy Project: Assessment Of Early Changes In Teachers’ Self-Reported Pedagogic Content Knowledge And Classroom Practice, Lorraine Jacob, Andrew Mcconney

Australian Journal of Teacher Education

The Fitzroy Valley Numeracy Project (FVNP) was designed to improve numeracy outcomes for Indigenous students by developing a systematic, co-ordinated approach to teaching primary school mathematics. In this study, using early project data, we examine FVNP teachers’ self‑reported pedagogic content knowledge and classroom practice from initial and follow up questionnaires, as well as interviews from case study teachers. After the first FVNP year, teachers reported being better able to plan focused mathematics lessons and to monitor student learning. On the other hand, teachers also felt less able to make mathematics explicit to students and their confidence in providing engaging activities …

Measure For Measure : A Review Of Outcomes Of School Education In Australia, John Ainley, Eveline Gebhardt

Assessment and Reporting

There have been a plethora of research reports providing information about the achievements of students in Australian schools and how those achievements differ among jurisdictions and among groups of students. However, each report has often been viewed in isolation from other similar studies. This report is intended to provide an integrated appraisal of the results of the international and national achievement surveys conducted since 1994 but with some references to earlier studies. In addition to limiting the task to manageable proportions, this time span corresponds to the widespread introduction of modern measurement methods so that there is a better basis …

An Sir Approach To Modeling Business Interactions In A Marketplace, Jessica R. Beiter

Theses

As interest in online coupons from distributors like Groupon and Living Social have grown, eBay has proposed and built a marketplace. This marketplace is called eBay Local. It is a place where local merchants can post coupons that distributors can bid on the right to publish. Based on some initial data, we have built a model to t and predict the growth of this marketplace. The influence of salesmen and organic growth convert potential merchants into active members of the marketplace posting their goods and services. We have modeled the recruitment and retention of businesses within the marketplace, based on …
