Using Remote Sensing Data To Predict The Spread Of Mosquito Borne Disease, Mary Ellen O'Donnell, Erika Podest

STAR Program Research Presentations

There is interest in how environmental variables derived from satellite data such as temperature, vegetation cover, and precipitation correlate to vector borne disease occurrence such as malaria and dengue fever. This study will be carried out using a decision tree based open source software called Random Forests to find correlations between the remote sensing variables and mosquito abundance. Software will be written in C# to take large amounts of data from the NASA satellite database and automatically format it for the Random Forest Software input. Correlations found, using Random Forests, between disease incidence and the variables can be used as …

Wind Speed And Seismic Motion Data Analysis, Margarita Vidrio

STAR Program Research Presentations

The Laser Interferometer Gravitational Wave Observatory (LIGO) was developed to exploit Einstein's prediction of gravitational waves to develop a new way to study the universe. Gravitational waves are detected by observing changes less than 1/10000 of the diameter of a proton in the distances between hanging mirrors that are four kilometers apart within two perpendicular evacuated tubes. These changes in distances between mirrors are produced by gravitational waves from large masses in space, such as colliding black holes. Many factors affect the sensitivity of the interferometer. LIGO’s Physical Environment Monitoring subsystem (PEM) is one method of both eliminating noise and …

Mother Convict Cichlids Inflict More Bites Upon An Intruder In Hot Temperatures, Jesse L. Heckendorf

STAR Program Research Presentations

Convict cichlids (Archocentrus nigrofasciatus) have developed to be extremely good parents by protecting their brood. Parental care leads to aggressive biting, chasing, and gill flaring to intimidate known predators. In this experiment, we show that environmental factors, such as the changing of temperature in this case, affect a female convict cichlid’s aggression toward caring for her offspring when an intruder is introduced. Females attack more in warmer water.

Injector Configuration And Development Of A Methodology To Scale Between Cold-Flow And Hot-Fire Evaluations, Ilian Angel Rojas, Nils Sedano

STAR Program Research Presentations

The Air Force Research Laboratory (AFRL) is undertaking a program to improve the development of a gas-centered swirl coaxial liquid injector. The injector in a liquid rocket engine atomizes and mixes the fuel with the oxidizer to produce efficient and stable combustion that will improve stability performance and provide the required thrust for the rocket engine without endangering hardware durability. The rocket injector has been experimentally investigated by using a combination of methodologies called cold-flow and hot-fire testing which have been scaled by other laboratory facilities. The AFRL identified few condition parameters for hot-firing testing that could be simulated through …

Experiential Learning At The Illinois Mathematics And Science Academy, Michelle Kolar, Dora Phillips, Christopher G. Kolar

Publications & Research

“Am I ever going to use this in the real world?” is a common question in science and math middle school and high school classrooms. Students taught using experiential learning techniques, however, already know the answer. They learn content by solving real world problems through hands-on activities. In other words, they learn science, technology, engineering, and math (STEM) the same way professionals do every day—by doing, sharing, and improving. Experiential learning provides the promise that the U.S. can reverse the trend of students losing interest in STEM subjects during middle school and create life-long learners who apply the scientific thought …

An Interpretive Plan Guide For Wilderness Park In Lincoln, Nebraska, Rachel J. Ward

Community and Regional Planning Program: Professional Projects

Wilderness Park, located in Lancaster County, Nebraska, is a public park of unique ecological and historical value to the city of Lincoln and to the surrounding region. The natural and historical features of the park present an opportunity to communicate environmental and historical topics that are relevant on local, national, and global levels, as well as inspire a lively sense of pride in the community. The problem is that many topics relevant to Wilderness Park are not currently being interpreted at the park, and that there are relatively few interpretive resources available to park visitors.

The purpose of this project …

Prospective Elementary Mathematics Teacher Content Knowledge: What Do We Know, What Do We Not Know, And Where Do We Go?, Eva Thanheiser, Christine Browning, Alden Edson, Jane-Jane Lo, Ian Whitacre, Dana Olanoff, Crystal Morton

Mathematics and Statistics Faculty Publications and Presentations

The authors reviewed 112 research studies from 1978 to 2012 on prospective elementary teachers' content knowledge in five content areas: whole numbers and operations, fractions, decimals, geometry and measurement, and algebra. Looking across these studies, this final paper identifies the trends and common themes in terms of the counts and types of studies and commonalities among findings. Analyses of the counts show that the number of articles published each year focusing on prospective teacher (PT) content knowledge is increasing. Most articles across the content areas show that PTs tend to rely on procedures rather than concepts. However, the focus of …

Impact Of Mathematics Computer-Assisted Instruction On English Language Learner Achievement, Christie Jacquelyn Jay

Graduate Theses and Dissertations

This quasi-experimental study examined the effect of supplemental mathematics computer-assisted instructional programs on the achievement of students in grades three and four over a two year period. This study evaluates the computer-assisted instruction (CAI) supplemental interventions through the lens of the sheltered instruction approach to teaching English Language Learner (ELL) students. The students who took part in the intervention attended nine elementary schools in one Arkansas district in the 2011-2012 and 2012-2013 school years. Data from Measures of Academic Progress (MAP) assessments were analyzed using a factorial ANOVA with pretest and two posttests over the course of two school years. …

A Grounded Theory Study On The Role Of Differentiated Instruction In Effective Middle School Science Teaching, Brian Jones

Doctoral Dissertations and Projects

The purpose of this grounded theory study was to develop a model explaining the role of differentiated instruction (DI) in effective middle school science teaching. The study examined the best teaching practices and differentiated elements from eight general education middle school science teachers, all scoring at the highest level of a teaching effectiveness measure on their evaluations, through a collection of observational, interview, survey, and teaching artifact data. The data were analyzed through the methodology of a systematic grounded theory qualitative approach using open, axial, and selective coding to develop a model describing how and to what degree effective middle …

The Relationship Between Teaching Approaches And Student Science Achievement For Four Racial Groups In Us Eighth Grade Classes, Su Gao

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lower science achievement and substantial racial performance gaps persist among students in the US. In the current reform of science teaching, inquiry-based science teaching is assumed effective in improving all student science learning in both scientific content and process and reducing learning gaps across racial groups. Conversely, traditional didactic science teaching is believed to be the most popular and has contributed to lower science achievement and the racial gap. These two assumptions, although central to science teaching reforms, cannot be empirically sustained in the existing literature on science teaching. Framed through the theoretical perspectives of inquiry-based instruction and culturally relevant …

Evaluating The Use Of The Math Reasoning Inventory For Improvement In Fraction Instruction, Kathy Huffman Boyer

Dissertations

In an attempt to close the mathematic achievement gap between students from the United States and students from other countries, a new national set of standards, the Common Core State Standards for Mathematics, was developed and adopted by the state of Michigan in 2010. These standards emphasize mathematical reasoning and application, rather than the previous emphasis on performing calculations. Unfortunately, teachers generally have had little training in how to assess students’ mathematical reasoning, how to teach mathematical reasoning, or how to provide remediation to those students who show need. The purpose of this study was to see if use of …

Gravity & Einstein: Assessing The Rubber Sheet Analogy In Undergraduate Conceptual Physics, Tiffany Rae Watkins

Boise State University Theses and Dissertations

The rubber sheet analogy for Einstein’s General Relativity model of gravity is a popular way to visualize the effect mass has on the curvature of spacetime. My single group, quasi-experimental study with repeated measures was designed to assess the effectiveness of the rubber sheet analogy in teaching gravitational fields. I developed instructional materials, including a hands-on lab, to engage university students in thinking about gravity using the rubber sheet analogy. Previous research on students’ ideas about gravity informed the development of the pre/post-test. My work is an important first step in establishing a standard assessment on gravity.

Approximately 97 students …

The Experiences Of Women In Post Graduate Physics And Astronomy Programs: The Roles Of Support, Career Goals, And Gendered Experiences, Ramón S. Barthelemy

Dissertations

In physics and astronomy the low representation of women is obvious at every stage of the educational pathway from undergraduate students to full professors. These low numbers perpetuate themselves by failing to create new mentors to foster the next generation of women. Women and men also have different experiences as they traverse into physics and astronomy careers. Women often experience chilly climates, discrimination, and challenges coordinating the demands of young families with their careers. In the literature exploring this topic, little focus is put on the experiences of women graduate students in physics and no focus is put on women …

Instructional Change In Academic Departments: An Analysis From The Perspective Of Two Environment-Focused Change Strategies, Kathleen M. Quardokus

Dissertations

Numerous reports demand changes in college and university teaching practices. This is especially true for science, technology, engineering and mathematics (STEM) disciplines. STEM stakeholders are concerned about student retention within STEM majors, as well as the lack of sufficient graduates with the knowledge to advance these fields. A common conclusion of these reports is that teaching practices must change. Although these calls for change have occurred for decades, STEM fields have yet to experience widespread change. Thus, there is a need for more effective change strategies. Recently, researchers have suggested that effective change strategies should focus on changing the environments …

Eliciting Elementary School Students’ Informal Inferential Reasoning Through Storytelling, Dustin Owen Smith

Dissertations

One growing area of research on statistical learning is Informal Inferential Reasoning (IIR). Makar and Rubin (2009) describe IIR as having three components: making and evaluating inferential claims, supporting claims explicitly with data, and attending to the inherent uncertainty present in statistical inference-making. This dissertation study was built around developing a method for providing opportunities for elementary school students (Grades K, 2, and 4) to engage with IIR within the context of stories and storytelling through a method called Storytelling-Questioning. After interacting with and discussing two separate stories, it was found that students of each grade level were able to …

A Qualitative Study Of Florida Tech Graduate Teaching Assistants’ Response To Coaching, Video Playback, And Coaching Paired With Video Playback With Regard To Their Concerns, Self-Reflections, And Practice Of Teaching, Angela Marie Fennell

Theses and Dissertations

Florida Tech’s campus-wide GTA professional development training, the GTA Seminar, has no clear theory on which it was designed, employs only measures of satisfaction and open-ended feedback, and performs limited follow-up on GTAs. Further, two pilot studies I conducted indicate that GTAs’ concerns may not be fully addressed by this seminar. This is notable because the GTA Seminar is often the only means of professional development available to more than half of the GTAs on campus. The purpose of my study was to investigate 13 GTAs’ teaching concerns, self-reflections, and practice when implementing three professional development sequences during their assignments …

Mathematical Content Knowledge For Teaching Elementary Mathematics: A Focus On Whole-Number Concepts And Operations, Eva Thanheiser, Ian Whitacre, George J. Roy

Mathematics and Statistics Faculty Publications and Presentations

This report represents part of a recent effort to summarize the state of knowledge of prospective elementary teachers' (PTs') mathematics content knowledge and the development thereof. Extensive reviews of the research literature were conducted by a recent PME-NA Working Group across various content areas. This report focuses on whole number and operations. Research in this area is scarce. What we do know from the literature is that PTs' knowledge of whole number and operations is insufficient and in need of improvement. PTs reason about whole numbers and operations in ways that are tied to the standard algorithms. At the same …

The Effects Of Combining Looping, Cognitively Guided Instruction, And Ethnicity: How They Can Collectively Improve Academic Achievement, Matthew Brandon Wilson
