Supporting Mathematics Understanding Through Funds of Knowledge

Description: Parents are often criticized for the types of roles they play in their children’s education. Rather than assuming parents do not contribute to their children’s learning, this study identified the various ways Hispanic parents support mathematics learning in the home. Using a funds of knowledge lens, the history, practices, and experiences of families that contributed to their children’s mathematics understanding was explored. The purpose of this study was to identify the unique funds of knowled… more

Computational Modeling of Small Molecules

Description: Computational chemistry lies at the intersection of chemistry, physics, mathematics, and computer science, and can be used to explain the behavior of atoms and molecules, as well as to augment experiment. In this work, computational chemistry methods are used to predict structural and energetic properties of small molecules, i.e. molecules with less than 60 atoms. Different aspects of computational chemistry are examined in this work. The importance of examining the converged orbitals obtained … more

The Impact of Computational Methods on Transition Metal-containing Species

Description: Quantum chemistry methodologies can be used to address a wide variety of chemical problems. Key to the success of quantum chemistry methodologies, however, is the selection of suitable methodologies for specific problems of interest, which often requires significant assessment. To gauge a number of methodologies, the utility of density functionals (BLYP, B97D, TPSS, M06L, PBE0, B3LYP, M06, and TPSSh) in predicting reaction energetics was examined for model studies of C-O bond activation of met… more

Elementary Pre-service Teachers’ Perceptions and Experiences of Mathematics Intervention and Response to Intervention Practices

Description: Response to intervention has become a widely implemented early intervention and pre-referral program in many schools due to the reauthorization of the 2004 Individuals with Disabilities Education Act. Limited studies exist that validate how teacher preparation programs are preparing the next generation of teachers to assess students, apply early academic interventions, monitor progress, and make educational decisions for students with learning difficulties as part of an RTI program. The purpose… more

Restricting Invariants and Arrangements of Finite Complex Reflection Groups

Description: Suppose that G is a finite, unitary reflection group acting on a complex vector space V and X is a subspace of V. Define N to be the setwise stabilizer of X in G, Z to be the pointwise stabilizer, and C=N/Z. Then restriction defines a homomorphism from the algebra of G-invariant polynomial functions on V to the algebra of C-invariant functions on X. In my thesis, I extend earlier work by Douglass and Röhrle for Coxeter groups to the case where G is a complex reflection group of type G(r,p,n) in… more

The Longitudinal Impact of Technology Immersion Through a One-to-One Mobile Technology Program on Reading and Math Performance in a Rural Title I Public School District

Description: In conjunction with the Texas Technology Immersion Pilot program (TIP), the State of Texas implemented a four-year annual evaluation called the Evaluation of the Texas Technology Immersion Pilot (eTxTiP). It focused on the technology immersion experience through one-to-one mobile technology of sixth grade students in 22 selected middle schools. Initial findings suggested academic growth, especially in math, increased rigor of student work, greater teacher collaboration, a more positive school e… more

Comparing Three Effect Sizes for Latent Class Analysis

Description: Traditional latent class analysis (LCA) considers entropy R2 as the only measure of effect size. However, entropy may not always be reliable, a low boundary is not agreed upon, and good separation is limited to values of greater than .80. As applications of LCA grow in popularity, it is imperative to use additional sources to quantify LCA classification accuracy. Greater classification accuracy helps to ensure that the profile of the latent classes reflect the profile of the true underlying sub… more

Optimal Strategies for Stopping Near the Top of a Sequence

Description: In Chapter 1 the classical secretary problem is introduced. Chapters 2 and 3 are variations of this problem. Chapter 2, discusses the problem of maximizing the probability of stopping with one of the two highest values in a Bernoulli random walk with arbitrary parameter p and finite time horizon n. The optimal strategy (continue or stop) depends on a sequence of threshold values (critical probabilities) which has an oscillating pattern. Several properties of this sequence have been proved by Dr… more

[The Brunsviga Calculator]

Description: Photograph of the Brunsviga calculator, held by UNT Special Collections. The calculator is silver in color and looks like a mini typewriter. The knobs on it are shiny red. The Brunsviga mechanical calculator was originally developed in 1891 and was manufactured until the 1970s when they were replaced by electronic calculators. This example was used by students and faculty in the NTSU Mathematics Department.

Transfer From a UTeach Replication Site to the Classroom: A Study of First and Second Year Instructional Practices

Description: Concerns based adoption model (CBAM) instruments were used to examine instructional practices of six graduates from a highly stylized, inquiry-based secondary math and science preparation program. Teachers were in the first or second years of teaching mathematics in six different secondary settings, ranging from poverty to wealthy schools. CBAM assumptions were tested. The primary assumption about concerns was that new teachers’ highest concerns would be within the self and task dimensions. Acc… more

Investigating Teachers’ Backgrounds and Instructional Practices to Improve Mathematics Teacher Training Programs

Description: In recent years, considerable concern has arisen over cross-national student’s math achievement. A number of studies focusing on eighth grade student’s math achievement have been published. However, the most important role we should consider is not only students, but also teachers. A good teaching training program could help teachers improve their teaching expertise and student’s math achievement. Moreover, most studies only focused on explained predictions of the effect between potential facto… more

Application of the Correlation Consistent Composite Approach to Biological Systems and Noncovalent Interactions

Description: Advances in computing capabilities have facilitated the application of quantum mechanical methods to increasingly larger and more complex chemical systems, including weakly interacting and biologically relevant species. One such ab initio-based composite methodology, the correlation consistent composite approach (ccCA), has been shown to be reliable for the prediction of enthalpies of formation and reaction energies of main group species in the gas phase to within 1 kcal mol-1, on average, of w… more
