Oscillation Theory Of Dynamic Equations On Time Scales, Raegan J. Higgins

Department of Mathematics: Dissertations, Theses, and Student Research

In past years mathematical models of natural occurrences were either entirely continuous or discrete. These models worked well for continuous behavior such as population growth and biological phenomena, and for discrete behavior such as applications of Newton's method and discretization of partial differential equations. However, these models are deficient when the behavior is sometimes continuous and sometimes discrete. The existence of both continuous and discrete behavior created the need for a different type of model. This is the concept behind dynamic equations on time scales. For example, dynamic equations can model insect populations that are continuous while in season, die …

C*-Extreme Points Of The Generalized State Space Of A Commutative C*-Algebra, Martha Gregg

Department of Mathematics: Dissertations, Theses, and Student Research

The generalized state space of a commutative C*-algebra, denoted S_H(C(X)), is the set of positive unital maps from C(X) to the algebra B(H) of bounded linear operators on a Hilbert space H. C*-convexity is one of several non-commutative analogs of convexity which have been discussed in this context. We show that a C*-extreme point of S_H(C(X)) satisfies a certain spectral condition on the operators in the range of an associated measure, which is a positive operator-valued measure on …

Science And Social Studies: The Forgotten Content, Samantha Slaughter

Mahurin Honors College Capstone Experience/Thesis Projects

Abstract The daily curriculum of many elementary schools lacks instructional time in the content areas of science and social studies. Many teachers insist that they do not have the time or training to cover these content areas on a daily basis. This project will illustrate that through proper planning, integration, and professional development, teachers can feel empowered to teach these content areas. The project includes a succinct explanation of how science and social studies can be included on a daily basis in the regular classroom setting, a detailed curriculum map, daily schedule, and four basic integrated units. The curriculum map …

A Program Evaluation Of Supplemental Instruction For Developmental Mathematics At A Community College In Virginia, Marilyn Lawson Peacock

Educational Leadership & Workforce Development Theses & Dissertations

With the current emphasis on accountability and the importance of math skills in our present economy, the success of developmental mathematics students at community colleges is critical. How to improve the success of these developmental students has become the impetus for many educational initiatives. One educational innovation in tutoring, called supplemental instruction, has been successfully applied to high-risk courses which are defined to have a failure rate in excess of 30%. Mid-Atlantic Community College, in its Title III grant which seeks to improve the success of developmental students, selected supplemental instruction as its initiative. This program evaluation investigated the effects …

A Closer Look At The Crease Length Problem, Sean F. Ellermeyer

Faculty Articles

An optimization problem that appears as an exercise in most modern calculus textbooks is the crease length problem. Here, Ellermeyer provides a solution of the general crease length problem in which all possible foldings of a corner to the opposite edge are taken into account. One of his findings will be that the minimum crease length is never produced by a Case 2 fold and hence that the general crease length problem always yields a different minimum than the constrained problem that is treated in the textbooks. He discovers a criterion that determines which foldings must be performed in order …

Similar But Different: The Complexities Of Students' Mathematical Identities, Diane Skillicorn Hill

Theses and Dissertations

We, as a culture, tend to lump students into broad categories to describe their relationships with mathematics, such as ‘good at math’ or ‘hates math.’ This study focuses on five students each of whom could be considered ‘good at math,’ and shows how the beliefs that make up their mathematical identities are actually significantly different. The study examined eight beliefs that affect a student's motivation to do mathematics: confidence, anxiety, enjoyment of mathematics, skill level, usefulness of mathematics, what mathematics is, what it means to be good at mathematics, and how one learns mathematics. These five students' identities, which seemed …

How Eighth-Grade Students Estimate With Fractions, Audrey Linford Hanks

Theses and Dissertations

This study looked at what components are in student solutions to computational estimation problems involving fractions. Past computational estimation research has focused on strategies used for estimating with whole numbers and decimals while neglecting those used for fractions. An extensive literature review revealed one study specifically directed toward estimating with fractions (Hanson & Hogan, 2000) that researched adult estimation strategies and not children's strategies. Given the lack of research on estimation strategies that children use to estimate with fractions, this study used qualitative research methods to find which estimation components were in 10 eighth-grade students' solutions to estimation problems involving …

Teaching High School Age Students With Special Needs The Four Situations For Subtraction, K. A. D. Miller, Audrey C. Rule, V. M. Macentee

Open Educational Resources

All learners, including those who qualify for special education services, should have access to learning mathematical concepts. This study examined the efficacy of using hands-on sets of materials to teach two high school students with mental retardation the four situations for subtraction. This is a mixed methods study using a simple pretest-posttest design to determine correct interpretation of subtraction story problems for different situations (take-away, comparison, completion, and whole-part-part) and correct regrouping during dynamic subtraction. Eight story problems were presented to the two participants eight weeks prior to instruction; students answered an identical posttest after twelve half-hour lessons on subtraction …

From College Prep High School Courses To College Remedial Courses : Bridging The Gap, Tracy K. Abar

Theses, Dissertations and Culminating Projects

This study investigated students’ use of, and access to, the calculator in high school mathematics courses and compared it to the accessibility of a calculator during college placement tests. In spring 1999, at the request of the College Board, the Educational Testing Service (ETS) conducted a survey on calculator use in the nation’s schools. Ninety-nine point nine percent of the schools surveyed indicated they either required or allowed calculators for part of their college preparatory mathematics sequence. Accompanying the increased role of calculators in mathematics learning and the use of technology in the classroom, significant changes were introduced into many …

Teacher As Designer: A Framework For Teacher Analysis Of Mathematical Model-Eliciting Activities, Margret A. Hjalmarson, Heidi Diefes-Dux

Interdisciplinary Journal of Problem-Based Learning

The study investigated tool development by three middle school mathematics teachers. The tools they designed were intended to support the use of model-eliciting activities (a form of instruction related to problem-based learning) and particularly the students’ presentations of their solutions for the whole class. The study examined the design and purposes for the presentation tools and resulted in a framework for categorizing teachers’ purposes for tools.The framework addressed the unit of analysis for the tools (individual students or groups of students) and the nature of teachers’ purposes for the tools. Design research was used as a theoretical perspective for conducting …

Dynamic Web Tools For Trigonometry, Steven J. Wilson

Innovations in Math Technology

In the last 20 years, computer technology having mathematical capability has been developed, improved, and become widely available, but textbook presentations are still largely free of any discussion that might require technology. Technology could be used in mathematical instruction for student drill and practice, for instructor demonstrations that promote conceptual understanding, or for the exploration of mathematical ideas, but software is often designed to be pedagogically generic, leaving its use to the creativity of the instructor. Technological solutions for local machines can be quite extensive, but cost and time constraints then limit availability for student use. The internet has the …

Promoting Student Collaboration In A Detracked, Heterogeneous Secondary Mathematics Classroom, Megan Staples

CRME Publications

Detracking and heterogeneous groupwork are two educational practices that have been shown to have promise for affording all students needed learning opportunities to develop mathematical proficiency. However, teachers face significant pedagogical challenges in organizing productive groupwork in these settings. This study offers an analysis of one teacher’s role in creating a classroom system that supported student collaboration within groups in a detracked, heterogeneous geometry classroom. The analysis focuses on four categories of the teacher’s work that created a set of affordances to support within group collaborative practices and links the teacher’s work with principles of complex systems.

A Descriptive Study Of The Impact Of Planning Time On The Utilization Of The National Council Of Teachers Of Mathematics Process Standards Within The Algebra 1 And Applied Mathematics Subject Fields, Kerri Colleen Lookabill

Theses, Dissertations and Capstones

Planning practices are necessary requirements for effective instruction. Their importance is illustrated in the guidelines produced by several national organizations such as The Interstate New Teacher Assessment and Support Consortium (INTASC), The National Board for Professional Teaching Standards (NBPTS), and The National Council of Teachers of Mathematics (NCTM). Planning time is considered important by teachers at the grassroots level in order for them to develop thought-provoking lessons that allow students to make connections and form meaning as well as to reflect on previous lessons in order to make improvements for subsequent lessons. Collaborative planning is also considered important; however, it …
