The Weak Discrepancy And Linear Extension Diameter Of Grids And Other Posets, Katherine Victoria Johnson

Department of Mathematics: Dissertations, Theses, and Student Research

A linear extension of a partially ordered set is simply a total ordering of the poset that is consistent with the original ordering. The linear extension diameter is a measure of how different two linear extensions could be, that is, the number of pairs of elements that are ordered differently by the two extensions. In this dissertation, we calculate the linear extension diameter of grids. This also gives us a nice characterization of the linear extensions that are the farthest from each other, and allows us to conclude that grids are diametrally reversing.

A linear extension of a poset might …

Comparing The Success And Experiences Of Developmental Algebra I Students, Christy Lowery-Carter

Doctoral Dissertations and Projects

Students enrolled during the spring 2011 and summer 2011 semesters taking developmental Algebra I were invited to participate in a study. Students were required to complete a researcher-made pretest prior to instruction, complete the course over the semester, and complete an identical posttest at the end of the course. The online students voluntarily completed a researcher-made survey. An ANCOVA analysis, using the pretest scores as a covariate, showed a significant difference between the online and seated students, as the online students scored significantly higher. The survey showed online students tended to utilize the captured lectures, with a larger percentage of …

Serious Game Design Principles: The Impact Of Game Design On Learning Outcomes, Michael W. Martin

Computational Modeling & Simulation Engineering Theses & Dissertations

This dissertation examines the research question "How do video game design principles affect learning outcomes in serious games?" This research first develops a theoretical foundation concerning the meaning of the terms "game" and "serious game". This conceptual clarification is broken down into analytic propositions, which state that games have participants, rules, goals and challenges, and synthetic propositions, which state that the games should be intrinsically compelling, provide meaningful choices, and be self encapsulated. Based on these synthetic propositions, three hypotheses were developed. The hypotheses are that games with an enhanced aesthetic presentation, more meaningful choices, or provide player competition will …

The Nature And Role Of Physical Models In Enhancing Sixth Grade Students' Mental Models Of Groundwater And Groundwater Processes, Debra Lynne Foster Duffy

Teaching & Learning Theses & Dissertations

Through a non-experimental descriptive and comparative mixed-methods approach, this study investigated the experiences of sixth grade earth science students with groundwater physical models through an extended SE learning cycle format. The data collection was based on a series of quantitative and qualitative research tools intended to investigate students' ideas and changes in ideas rather than measure their achievement. The measures included a groundwater survey, classroom observations, and one-on-one follow-up student interviews for triangulation of data sources. The research was carried out at a K-12 independent school in eastern Virginia using two classes of sixth grade earth science students (n=30).

This investigation evaluated the effects of the use of the pedagogical tool "Evo in the News" on the attitudes toward and knowledge of biological evolution in a sample of undergraduate non-major biology students at a large, private research university. In addition, this study looked at the initial attitudes of the students and their knowledge of evolution before beginning a second semester introductory biology course. Both the initial attitudes and knowledge of the students and the gains in positive attitudes and knowledge were measured using the Evolutionary Attitudes and Literacy Survey (EALS). The goal of the research was to analyze potential …

Examining The Mediation Of Power In A Collaborative Community: Engaging In Informal Science As Authentic Practice, Anton Puvirajah, Geeta Verma, Horace Webb

Education Publications

Focusing on the interplay of context and language, this study examined a group of high school students and their mentors’ use of language during a robotics competition. This informal setting allowed us to gain insights into the mediation and manifestation of power within the group. Using critical discourse analysis of competition transcripts and interviews we found that both students and mentors felt a sense of ownership and community leading to symmetry in power amongst them. The shift in power led to greater student ownership and agency and created a space for authentic and meaningful science learning. The context of the …

Enhancing Content Knowledge Of In-Service Science Teachers Through Model And Modeling, Naheed Perveen, Sadia Muzzafar Bhutta

Institute for Educational Development, Karachi

The guiding question for this paper is; how does model and modeling enable student-teachers to develop a conceptual understanding of the cell as a structural and functional unit of living things? A teaching unit ‘The Cell’ was designed in view that models are a major teaching and learning tool for developing scientific thinking, whereas modeling means a process of forming representation. The teaching and learning strategies reported here encapsulated four modeling phases. Firstly, student-teachers modeled historical development of cell through a time line and role play and discussed the evolutionary and tentative nature of science. Secondly, the candy factory analogy …

A Study Of The Relationship Between Caregiver Education Level, Time Spent On School Actvities, And Mathematics Achievement, Ebony Allen

Doctoral Dissertations and Projects

This study examined the relationship between caregiver education level and time spent with a caregiver on school activities with regard to how Georgia Middle School students (N = 465) achieved on the mathematics section of the yearly Criterion Referenced Competency Test (CRCT) in Georgia. Caregiver education level and time spent with the caregiver on school activities was also examined to determine if a cumulative effect between the two factors could be found in relation to mathematics achievement on the CRCT. A causal comparative design was used and the data was analyzed using the 2009 version 16 of SPSS. A generalized …

Teaching Introductory Programming Concepts: A Comparison Of Scratch And Arduino, Anne Beug

Master's Theses

Computing has become an integral part of modern America. The Bureau of Labor Statistics estimates that between 2008 and 2018, the United States will have 1.4 million job openings in computing fields [1]. Since the early 2000's (just after the "dot com bust"), the number of students enrolled in computing majors (Computer Science, Computer Engineering, etc.) dropped precipitously by over 50%, only starting to rise again in 2009 [2]. One way to rectify to this gap between demand and supply is to start training students in computational thinking during high school. While the Computer Science Advanced Placement AB test has …

An Alternative Method: Using Novels In Mathematics To Teach The Concepts, Rachel Frances Colby

Undergraduate Honors Thesis Collection

This paper explains a research project conducted exploring the effectiveness of using the novel, The Number Devil, to teach math concepts. The effectiveness was measured by if students met the standards, if students understood the concepts, and if students enjoyed the method of instruction. The reason for conducting this research was to look at new ways of teaching mathematics due to the thought that many students dislike and do not understand math. Using novels could prove to be an effective way to vary the instruction and teach difficult concepts. To complete this research, I taught a class the math …

Getting To The "Why": Teacher Practices That Support Mathematically Sound Student Justifications, Briana Hennessy

Honors Scholar Theses

Though the mathematical and education communities both value justification and argumentation in the middle grades classroom, teachers have historically found these practices difficult to support. This article discusses teaching practices that are associated with high levels of mathematically acceptable argumentation by students. Data were collected on seven committed teachers who explored justification and then implemented the same justification task over two years. Thus, the data reflected fourteen different implementations of the same task, allowing us to compare lessons directly. The findings describe how teachers’ Focusing Students’ Mathematics and Providing Scaffolding Questions are consistently associated with high levels of justification, while …

Data were collected from three observations in each of the five classes as well as observations from trained professional development staff working on the field-test and teacher exit interviews. Results indicated that in four of the five classes two-thirds of the centers related to the unit objectives and students spent over 90% of time in unit related centers. There were a variety of …

Bar Graphs & Baselines: Student Perceptions Of Distortions In Real World Graphs, Robert K. Janes Iii

Honors Scholar Theses

It is important for every educated member of our society to be able to read, comprehend, and interpret graphs. To that end, the National Council of Teachers of Mathematics (NCTM) and the Common Core State Standards have endorsed a kindergarten through eighth-grade mathematics curriculum that is rich in data analysis and graphical literacy skills. These skills are important, as graphs in the public sphere may include certain features that can cause misperceptions of the data. Such features may be intentional or unintentional and can include non-zero baselines, representing data with extra dimensions, stretching and shrinking graphics, not displaying outliers, and …

Manipulatives And The Growth Of Mathematical Understanding, Stacie Joyce Gibbons

Theses and Dissertations

The purpose of this study was to describe how manipulatives facilitated the growth of one group of high school students' mathematical understanding of combinatorics and Pascal's Triangle. The role of manipulatives in mathematics education has been extensively studied, but much of the interest in manipulatives is focused on the general uses of manipulatives to support student learning. Unfortunately, there is a lack of research that explicitly defines how manipulatives can help students develop mathematical understanding. I have chosen to examine mathematical understanding through the lens of the Pirie-Kieren Theory for Growth of Mathematical Understanding. Through analysis of the students' explorations …
