Evaluation Of The Utility Of Informative Priors In Bayesian Structural Equation Modeling With Small Samples, Hao Ma May 2020

Evaluation Of The Utility Of Informative Priors In Bayesian Structural Equation Modeling With Small Samples, Hao Ma

Department of Education Policy and Leadership Theses and Dissertations

The estimation of parameters in structural equation modeling (SEM) has been primarily based on the maximum likelihood estimator (MLE) and relies on large sample asymptotic theory. Consequently, the results of the SEM analyses with small samples may not be as satisfactory as expected. In contrast, informative priors typically do not require a large sample, and they may be helpful for improving the quality of estimates in the SEM models with small samples. However, the role of informative priors in the Bayesian SEM has not been thoroughly studied to date. Given the limited body of evidence, specifying effective informative priors remains ...

Presence Of Electron Donor/Acceptor Radiographic Contrast Media In Unusual Photosynthesis Environment Of Fresh Plant Cells: Near-Infrared And X-Ray Characterization, Tetiana Soloviova, Subhendra Sarkar, Amina Shahbaz, Aldona Gjoni

Publications and Research

Photosynthesis is a chemical process through which light energy is used to convert inorganic material (water and carbon dioxide) into organic molecules. Anaerobic photosynthesis, also known as anoxygenic photosynthesis, is the process by which certain bacteria use light energy to create organic compounds but do not adequately involve oxygen. In this experiment we are trying to influence photosynthesis (light and dark reactions: PS-I and PS-II by electron rich gadolinium/iodine complexes like Eovist and Isovue. We also performed X-ray and NIR reflection spectroscopy (NIRS) to measure Gd difusivity and PS-I/II infrared response. The results for X-ray (45kvp and 5 ...


Introductory Calculus: Through The Lenses Of Covariation And Approximation, Caleb Huber May 2020

Introductory Calculus: Through The Lenses Of Covariation And Approximation, Caleb Huber

Graduate Student Portfolios, Papers, and Capstone Projects

Over the course of a year, I investigated reformative approaches to the teaching of calculus. My research revealed the substantial findings of two educators, Michael Oehrtman and Pat Thompson, and inspired me to design a course based upon two key ideas, covariation and approximation metaphors. Over a period of six weeks, I taught a course tailored around these ideas and documented student responses to both classroom activities and quizzes. Responses were organized intonarratives, covariation, rates of change, limits, and delta notation. Covariation with respect to rates of change was found to be incredibly complex, and students would often see it ...

Exploring Pedagogical Empathy Of Mathematics Graduate Student Instructors, Karina Uhing May 2020

Exploring Pedagogical Empathy Of Mathematics Graduate Student Instructors, Karina Uhing

Dissertations, Theses, and Student Research Papers in Mathematics

Interpersonal relationships are central to the teaching and learning of mathematics. One way that teachers relate to their students is by empathizing with them. In this study, I examined the phenomenon of pedagogical empathy, which is defined as empathy that influences teaching practices. Specifically, I studied how mathematics graduate student instructors conceptualize pedagogical empathy and analyzed how pedagogical empathy might influence their teaching decisions. To address my research questions, I designed a qualitative phenomenological study in which I conducted observations and interviews with 11 mathematics graduate student instructors who were teaching precalculus courses at the University of Nebraska—Lincoln.

Physical Science - Gravity On Earth: Gravitational Force, Patrick Young May 2020

Physical Science - Gravity On Earth: Gravitational Force, Patrick Young

Model NGSS Lessons: 4th - 5th Grade

Gravity is a curious property of our universe. Gravity causes objects to attract each other with a force. The strength of this force depends on the masses of the objects and their distance apart. The direction of the force is from the center of one object toward the center of the other. Although the force is invisible, we can observe its direction by watching how objects move in response to the force.


Physical And Life Science - Food And Energy: Animal And Plant Energy, Cassandra Armstrong May 2020

Physical And Life Science - Food And Energy: Animal And Plant Energy, Cassandra Armstrong

Model NGSS Lessons: 4th - 5th Grade

Energy exists in many forms and is constantly being transferred between forms. All energy types can be sorted into two main categories: potential and kinetic. Potential energy is stored energy. Chemical energy, nuclear energy, stored mechanical energy, and gravitational energy are all examples of potential energy. Kinetic energy is the energy of motion. Radiant (light) energy, thermal energy, sound energy, and electrical energy are all examples of kinetic energy. Energy cannot be created or destroyed, only transferred between the types of energy. Most energy we use on Earth stems from the nuclear energy from within the sun.

There are many misconceptions about earth’s orbit but it is important to remember and to convey to students that Earth is moving around the Sun and the Moon is moving around us. What we see each day with the motion of the Sun moving across the ...


The Marshmallow Lab: A Project-Based Approach To Understanding Functional Responses, Melissa Pulley May 2020

The Marshmallow Lab: A Project-Based Approach To Understanding Functional Responses, Melissa Pulley

All Graduate Theses and Dissertations

This paper presents a three-part lesson plan to improve student’s understanding of Holling’s type II functional response model. This model describes the interaction between a predator and how much it is able to consume given a constant number of prey. According to the model, while increased availability of prey allows predators to consume portionately more prey for low values, after some number of prey, predators will only be able to capture a limited number of prey even as the prey continues to increase. This phenomenon is known as saturation. Holling first develop this important ecological theory through his ...


Physical Science - Under Pressure: Matter And Its Interactions, David Hernandez, Elizabeth Martinez May 2020

Physical Science - Under Pressure: Matter And Its Interactions, David Hernandez, Elizabeth Martinez

Model NGSS Lessons: 4th - 5th Grade

Air pressure, or atmospheric pressure, is the force exerted on objects by the atmosphere. Barometers are typically used to measure atmospheric pressure. Made of a liquid filled glass tube, the level of liquid will rise when the pressure increases and fall when the pressure drops. Lower barometric pressure tends to be associated with precipitation and cloudiness, while higher readings are related to sunshine and calmer weather. Air is made of invisible particles. The density of these particles is affected by atmospheric pressure. The greater the pressure, the more densely packed the particles are. In comparison, less pressure means a lower ...
