Fostering Metacognition In The Middle School Classroom: An Exploration Of Teachers' Practices, Markeya S. Peteranetz

College of Education and Human Sciences: Dissertations, Theses, and Student Research

This thesis investigated how middle school teachers foster metacognition through instruction. Metacognition is the knowledge and awareness of one’s thinking as well as monitoring and control of thought processes. Metacognition is related to student achievement and can be increased through both implicit and explicit instruction. Explicit instruction takes place when the teacher points out, explains, or discusses the benefits of metacognition. Implicit instruction occurs when the teacher models or prompts the use of metacognition without expressly acknowledging or discussing it. This thesis used both quantitative and qualitative methods to determine the extent that metacognition is fostered in middle school classrooms …

Influences On Student Attitudes About U.S. Involvement In Nation-Building, Tobin C. Beck

Department of Political Science: Dissertations, Theses, and Student Research

How do college students form opinions about a complex foreign policy issue such as U.S. involvement in nation-building? My study shows that in 2012, students identifying as conservative tended to support nation-building in proportion to their perception of the strength of their own and their parents' conservatism. The association between perception of conservatism and support for nation-building was statistically significant in 2012, although there was no statistically significant overall association between student political ideology and support for U.S. involvement in nation-building. However, a relationship between conservative student perception of ideology and support for nation-building was not detected in 2011 data. …

Decision Support Tools To Address Climate Change: Climate Model–Land Surface Models, Zea Mays L. (Corn) Phenology And Evapotranspiration–Yield Sensitivity Models For Nebraska, Usa, Jane A. Okalebo

School of Natural Resources: Dissertations, Theses, and Student Research

Nebraska's climate is highly variable and is expected to change in the future with anthropogenic global warming (AGW), resulting in warmer spring and summer temperatures coupled with more erratic rainfall events. This has strong implications for agriculture in the region, yet it is not clear that current modeling and decision-support tools are adequate to address these looming changes and provide planning, mitigation and adaptation strategies. To address climate change and its implications to agriculture in Nebraska, a set of robust decision support tools are very crucial. This study herein are divided into three chapters, with each chapter addressing a specific …

Cloud Impacts On Pavement Temperature And Shortwave Radiation, Curtis L. Walker

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Forecast systems provide decision support for end-users ranging from the solar energy industry to municipalities concerned with road safety. Pavement temperature is an important variable when considering vehicle response to various weather conditions. A complex, yet direct relationship exists between tire and pavement temperatures. Literature has shown that as tire temperature increases, friction decreases which affects vehicle performance. Many forecast systems suffer from inaccurate radiation forecasts resulting in part from the inability to model different types of clouds and their influence on radiation. This research focuses on forecast improvement by determining how cloud type impacts pavement temperature and the amount …

Identification Of Groundwater Sources For Municipal Wells Using Geochemical Data On The Platte Alluvial Aquifer And Underlying Limestone At The Lincoln Water Well Field Near Ashland Nebraska, Juanita Cruz Torres

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Alluvial aquifer systems where pumping of municipal wells induces recharge from the adjacent river are the primary source of water for many cities. The city of Lincoln, NE has a primary water source in an alluvial aquifer adjacent to the Platte River. The Lincoln Water System manages the stream/aquifer system by using integrated models for a better understanding during periods of high stress such as a drought. The integrated models set the limestone aquifer as an impermeable boundary to understand the alluvial aquifer system without having a secondary water source. The limestone aquifer is permeable and the purpose of this …

Development And Application Of Combined Quantum Mechanical And Molecular Mechanical Methods, Rui Lai

Department of Chemistry: Dissertations, Theses, and Student Research

Compromising of computational cost and accuracy, combined quantum mechanical and molecular mechanical (QM/MM) methods are practical methods for studying large molecular systems. The use of induced dipole polarizable force fields can significantly improve the accuracy of MM and QM/MM methods. However, induced dipole models tend to overestimate the polarization energy at short interaction distances. Damping functions can be applied to reduce the over polarization. MM-MM damping schemes have been developed to correct the overestimated polarization between MM atoms; QM-MM damping scheme has not been developed. In this thesis, a QM-MM damping scheme is developed for the damping of the MM …

Keeping up with technological innovations is a challenge for educational intuitions as they strive to prepare students to be competitive in a future workforce. This is an overwhelming task for educational leaders that extends beyond which technological device to purchase. This study examines the barriers to iPad integration in education and how the gradual release of responsibility method of instruction can be used to increase participants’ self-efficacy with iPads. The participants (N = 41) were teacher education graduate candidates enrolled in a Children’s Literature course in which they were provided access to iPads. Survey results revealed that candidates’ efficacy prior …

Teaching Beyond The Assessment, Daniel R. Ilaria

Mathematics Faculty Publications

This paper discusses how students can learn mathematics assessed on standardized testing in a way that promotes deeper thinking about the mathematics. While potential assessments aligned to the Common Core Content Standards drive the focus of the curriculum, technology can provide a way for delving into conceptual understanding. Using two standardized test questions, this paper provides examples of how technology can promote deeper thinking about mathematical concepts than what is supposed to be assessed in the questions.

Media Sensationalism And Its Implications On The Public Understanding Of Science, Christopher Barsoum

HIM 1990-2015

Myths, misinformation, and sensationalism. These are common enemies that directly inhibit the public understanding of science. In particular, the media is often responsible for mishandling or otherwise misrepresenting scientific information, historically and presently speaking. Many sources can combat the public understanding of science through pseudoscientific means. This includes but is not limited to religion, the media, politics, or just simple hearsay. For example, Young Earth creationism is deeply rooted in Christian theology, but the beliefs hold no scientific basis. Yet, almost half of Americans still believe in Young Earth creationism. Another such example is anti-vaccination campaigns due to fears of …

The Florida Department of Education revised the Common Core State Standards into what are now known as the Florida Standards in February 2014, approving 99 revisions to the original standards that were accepted in 2010 (Dunkelberger, 2014). The purpose of this research was to identify current teachers# attitudes towards the new Language Arts Florida Standards (LAFS), specifically regarding teachers# perceptions of text complexity and close reading as enacted in the reading curriculum. Additionally, this study will attempt to identify how teachers# attitudes impact their implementation of the new standards. This research used a self-administered survey to collect the teacher perceptions …

Predicting Science Literacy And Science Appreciation, Robert Hellmuth

HIM 1990-2015

Research has shown that the benefits of having a populace literate in science are great. Even if citizens are not literate in basic science, it is important that citizens still appreciate science and those with expertise in the field for many reasons. Recent research suggests that the United States (U.S.) has lower levels of science literacy than it should. Evidence may also suggest that many U.S. citizens are not appreciative of science. Overall, little research has been conducted on what may predict science literacy and science appreciation which is the aim of this research. Specifically, I have examined socio-personal variables, …

This study analyzes high, middle, and low quality education systems around the world and the infrastructures that lead to educational success or failure. Fifteen education systems …

Elementary Pre-Service Teachers' Perceptions Of Thematic Unit Instruction Versus Single-Subject Instruction, Shana Shea

HIM 1990-2015

The focus of this research project was to determine whether thematic unit instruction or traditional, single-subject instruction was perceived to be the more effective and engaging way of teaching as decided by pre-service teachers. Research has shown that incorporating multiple subjects into one unit or topic of study helps to create more engagement and connections to which students can relate. In creating these connections, students can relate the content to their real life and in turn, better comprehend and retain the material. The pre-service teachers attend the University of Central Florida's College of Education and Human Performance. They voluntarily participated …

The Changes That Preservice Teachers Have Seen In The Attitudes Of Teachers About Social Studies In Elementary Schools, Katherine Syracuse

HIM 1990-2015

Ever since national legislation has become involved in the testing of our students, the face of social studies education in elementary school classrooms has changed drastically. With the passage of Goals 2000 in 1993, social studies instruction in elementary school classrooms has seen a steep decline in the time allotted. Also, the attitude of administrators and teachers in elementary schools has taken away the importance of social studies in the classroom. While social studies has seen a big change in the amount of time dedicated to instruction in the past 20 years, there is still hope for the important topics …

The Unified-Fft Method For Fast Solution Of Integral Equations As Applied To Shielded-Domain Electromagnetics, Brian J. Rautio

Dissertations - ALL

Electromagnetic (EM) solvers are widely used within computer-aided design (CAD) to improve and ensure success of circuit designs. Unfortunately, due to the complexity of Maxwell's equations, they are often computationally expensive. While considerable progress has been made in the realm of speed-enhanced EM solvers, these fast solvers generally achieve their results through methods that introduce additional error components by way of geometric approximations, sparse-matrix approximations, multilevel decomposition of interactions, and more. This work introduces the new method, Unified-FFT (UFFT). A derivative of method of moments, UFFT scales as O(N log N), and achieves fast analysis by the unique combination of …

Lacustrine Turbidites From Tropical African Lakes As Indicators Of Hydrologic And Climatic Changes, Xuewei Zhang

The Synthesis, Characterization, And Application Of Carborane-Cluster Based Macrocycles And Boron Nitride Nanosheets In Photovoltaics, Christopher Robert Petrelli

Dissertations - ALL

Chapter 1: Dye-sensitized solar cell (DSSC) efficiencies have not significantly improved in recent years, primarily because of their single band gap design, limitations in dye absorption energies, and the Shockley-Queisser (SQ) limit. DSSCs require incident photon energy in the visible spectrum for the cell to produce a usable current. While the possibility of absorbing two

near-infrared photons is a known concept for surmounting the SQ limit, the opportunities presented by mesoporous systems for creating such a sensitizer do not appear to have been studied. By incorporating carborane cluster-based macrocyclic compounds as "electron reservoirs," a number of the inherent limitations in …

Discrete Gate Sizing Methodologies For Delay, Area And Power Optimization, Jiani Xie

Dissertations - ALL

The modeling of an individual gate and the optimization of circuit performance has long been a critical issue in the VLSI industry. In this work, we first study of the gate sizing problem for today's industrial designs, and explore the contributions and limitations of all the existing approaches, which mainly suffer from producing only continuous solutions, using outdated timing models or experiencing performance inefficiency.

In this dissertation, we present our new discrete gate sizing technique which optimizes different aspects of circuit performance, including delay, area and power consumption. And our method is fast and efficient as it applies the local …

Distinct Conformational Behaviors Of Four Mammalian Dual-Flavin Reductases (Cytochrome P450 Reductase, Methionine Synthase Reductase, Neuronal Nitric Oxide Synthase, Endothelial Nitric Oxide Synthase) Determine Their Unique Catalytic Profiles, Mohammad Mahfuzul Haque, Mekki Bayachou, Jesus Tejero, Claire T. Kenney, Naw M. Pearl, Sang-Choul Im, Lucy Waskell, Dennis J. Stuehr

Chemistry Faculty Publications

Multidomain enzymes often rely on large conformational motions to function. However, the conformational setpoints, rates of domain motions and relationships between these parameters and catalytic activity are not well understood. To address this, we determined and compared the conformational setpoints and the rates of conformational switching between closed unreactive and open reactive states in four mammalian diflavin NADPH oxidoreductases that catalyze important biological electron transfer reactions: cytochrome P450 reductase, methionine synthase reductase and endothelial and neuronal nitric oxide synthase. We used stopped-flow spectroscopy, single turnover methods and a kinetic model that relates electron flux through each enzyme to its conformational …

Composite Panel Impact Testing For The Down-Selection Of Material For Use In The Outer Shell Of Football Helmets, Natalie Genevieve Patzin

All Theses

Each year, there are an estimated 3.8 million sports-related concussions that occur in the United States alone, the majority occurring during football collisions. These staggering numbers occur even with the use of mandated protective helmets, which are designed to decrease potential brain injuries. The outer shell of a football helmet acts as a shield for vulnerable areas of the cranium by providing the initial impact force dispersion to allow a more distributed load to be transferred to the inner foam padding. The current material standard for the exterior casing is a polycarbonate blend. Multiple studies demonstrate insufficiencies in current helmets …
