The Computation Choices Made By Students In Years 5 To 7, Paul Swan

Theses: Doctorates and Masters

This study was designed to explore the computation choices made by 78 students in Years 5 to 7. The ability to choose and use a repertoire of computation methods is an important goal of mathematics education. While one might expect to find a great deal of research outlining the computation choices students make and why they make them, this was not the case; and as such it was decided to explore what computation choices students make and why they make them.

The year levels chosen were 5, 7 and 9. There were two classes from each chosen primary school representing Year 5 and Year 7 and three classes of Year 9 from the high school. The total number of students involved was 91, 77 and 73 from the three respective year levels. Instruments used for collecting …

Effect Of Applied Academics On The Final English Course Grade Of Associate Of Science Degree Students In Automotive Service Management Technology, Kathleen Habel

Abraham S. Fischler College of Education ETD Archive

Traditionally, students enrolled in two-year Automotive Service Management Technology degree programs, had a difficult time succeeding in required general education courses, especially math, English composition, and physics. They enrolled in classes open to the general student population but found that the material had little meaning or relevance to their chosen field of study. According to college records, the pass rate was less than the norm for liberal arts students. Because of this, faculty and staff decided that class material needed to be presented through applied academics. The new curriculum demonstrated the relevance of subject matter in general education classes to …

Development Of Cfl-Free, Explicit Schemes For Multidimensional Advection-Reaction Equations, Hong Wang, Jiangguo Liu

Faculty Publications

We combine an Eulerian–Lagrangian approach and multiresolution analysis to develop unconditionally stable, explicit, multilevel methods for multidimensional linear hyperbolic equations. The derived schemes generate accurate numerical solutions even if large time steps are used. Furthermore, these schemes have the capability of carrying out adaptive compression without introducing mass balance error. Computational results are presented to show the strong potential of the numerical methods developed.

An Analysis Of The Academic Success Achieved By Five Freshman Cohorts Through A Community College Developmental Education Program., Nancy K. Gray-Barnett

Electronic Theses and Dissertations

The challenge of underprepared students' entering America's colleges and universities is not new. Because of their "open door" policies, community colleges are more likely to enroll students who are not college prepared. This retrospective study focused on the performance of students who had completed required developmental education courses compared to the performance of students without developmental requirements. The study examined developmental education success measures for five cohorts of first-time degree-seeking freshmen each tracked for a six-year period enrolled at Walters State Community College located in Tennessee.

The success measures compared included grade point averages earned in college-level mathematics and English …

Chords Of Longest Circuits Of Graphs, Xuechao Li

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis is on a long standing open conjecture proposed by one of the most prominent mathematicians, Dr. C. Thomassen: Every longest circuit of 3-connected graph has a chord. In 1987, C. Q. Zhang proved that every longest circuit of a 3-connected planar graph G has a chord if G is cubic or if the minimum degree is at least 4. In 1997, Carsten Thomassen proved that every longest circuit of 3-connected cubic graph has a chord.;In this dissertation, we prove the following three independent partial results: (1) Every longest circuit of a 3-connected graph embedded in a projective plane …

Literary Evidence For Roman Arithmetic With Fractions, David W. Maher, John F. Makowski

Classical Studies: Faculty Publications and Other Works

Roman arithmetic is a perennially troubling subject for both classicists and mathematicians. Scholars universally comment on the difficulty posed by Roman alphabetical notation both in expressing simple figures and in doing written calculations. For example, Lloyd Motz and Jefferson Weaver with exasperation ask, "How ... can anyone do any arithmetic with DCCCLXXXVIII, the Roman equivalent of 888?," and Florian Cajori concludes that the Romans must have resorted to the abacus in order to multiply a number like 723 (DCCXXIII) by 364 (CCCLXIV).' Yet our sources, literary and inscriptional, indicate that the Romans were capable of highly sophisticated calculations, and, of …

Affinity Learning In Mathematics, Arthur I. Zygielbaum, Neal Grandgenett

Teacher Education Faculty Proceedings & Presentations

Teaching complex subjects such as mathematical modeling is intrinsically challenging. It is more so in a typical classroom setting. In this paper, we explore the use of technology to provide an electronic tutor that interacts with both teacher and student to provide a personalized and focused learning experience. Affinity Learning is an environment that captures the skills of a master teacher in a dynamic but simple technical embodiment and presents lessons and assessments online to a student. Initial results not only indicate that learning has occurred, but also distinguish male from female performance and give interesting insight into the learning …

Dynamic Coloring Of Graphs, Bruce Montgomery

Graduate Theses, Dissertations, and Problem Reports (ETD)

In this dissertation, we introduce and study the idea of a dynamic coloring of a graph, a coloring in which any multiple-degree vertex of the graph must be adjacent to at least two color classes.;As parts of the overall research, we study (for some interesting subjects of colorings) the corresponding subjects of dynamic colorings, we compare the chromatic number and dynamic chromatic number, and we study some problems unique to dynamic colorings. Also, we introduce and briefly study a generalization of dynamic coloring.;The interesting subjects of colorings we consider are the chromatic number of important graphs, upper bounds of the …

Set-Theoretic And Algebraic Properties Of Certain Families Of Real Functions, Krzysztof Plotka

Graduate Theses, Dissertations, and Problem Reports (ETD)

Given two families of real functions F1 and F2 we consider the following question: can every real function f be represented as f = f 1 + f2, where f1 and f2 belong to F1 and F2 , respectively? This question leads to the definition of the cardinal function Add: Add( F1,F2 ) is the smallest cardinality of a family F of functions for which there is no function g in F1 such that g + F is contained in F2 . This work is devoted entirely to the study of the function Add for different pairs of families of …

Approximating Eigenvalues For Double Well Potentials., Chad Fulk

Student Work

One dimensional double well potentials usually refer to those potentials which have two equivalent or non-equivalent minima. They have been used to model diverse systems ranging from the electronic structure of diatomic molecules to electron-lattice coupling in high temperature superconductors [1][2]. However, one difficulty to the utility of these models is that exact analytical solutions for almost all double well potentials have not been found, in spite of the fact that this type of potential is constantly utilized as an illustra­tive example in the literature. Despite intensive research into this problem, only a few types of double wells have been …

Mathematical Constance (A Poem Dedicated to Constance Reid)

I think that I shall never see

A constant lovelier than e,

Whose digits are too great too state,

They're 2.71828…

And e has such amazing features

It's loved by all (but mostly teachers).

With all of e's great properties

Most integrals are done with … ease.

Theorems are proved by fools like me

But only Euler could make an e.

I suppose, though, if I had to try

To choose another constant, I

Might offer i or phi or pi.

But none of those would satisfy.

Of all the …

Mathematics Achievement In Tennessee Schools In The Context Of Opportunity To Learn., Richard Lee Kitzmiller

Electronic Theses and Dissertations

This study examines the relationship of student achievement in mathematics and factors purported to influence such achievement. The factors utilized in the study were selected from those contained in accountability reports issued by the state of Tennessee in 1995-96. The student achievement measures were based on four high school end-of-course mathematics tests. Student performance on these tests is examined both in terms of actual scores and value-added measures. This study organizes the available accountability measures in an Opportunity-to-Learn (OTL) framework for the purpose of determining relationships that can inform practice and give policy guidance.

The study examined 65 (of 139) …

Incorporating Technology In Mathematics Education: A Suite Of E-Activities For The Modem Mathematics Classroom, Jennifer E. Youngberg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

National studies indicate major deficiencies in students' understanding of mathematics. Research suggests that students tend to view mathematics as a set of computational rules rather than a process of discovery and a tool for problem-solving. Most students fail to grasp the concepts behind the computations.

Technology provides a partial solution to this problem. Over the past decade, computers have emerged as a powerful tool in education. Computers place the control of action in the learning process with the student. They allow students to experiment with, explore, and discover mathematics at their own pace. With computers, students can consider more examples …

Abstracting Aristotle’S Philosophy Of Mathematics, John J. Cleary

Research Resources

In the history of science perhaps the most influential Aristotelian division was that

between mathematics and physics. From our modern perspective this seems like an unfortunate deviation from the Platonic unification of the two disciplines, which guided Kepler and Galileo towards the modern scientific revolution. By contrast, Aristotle’s sharp distinction between the disciplines seems to have led to a barren scholasticism in physics, together with an arid instrumentalism in Ptolemaic astronomy. On the positive side, however, astronomy was liberated from commonsense realism for the conceptual experiments of Aristarchus of Samos, whose heliocentric hypothesis was not adopted by later astronomers because …

Stochastic Comparision And Dependence Among Order Statistics,Spacing And Concomitants Of Order Statistics., Baha-Eldin Khaledi Dr.

Doctoral Theses

The simplest and the most common way of comparing two random variables is through their means and variances. It may happen that in some cases the median of X is larger than the median of Y, while the mean of X is smaller than the mean of Y. However, this confusion will not arise if the random variables are stochastically ordered. Similarly, the same may happen if one would like to compare the variability of X with that of Y based only on numerical measures of variability. Besides, these characteristics of distributions might not exist in some cases. In most …
