The Language Of Professional Development Leaders, Andrew Riffel, Kathleen Mary Melhuish, Eva Thanheiser

Mathematics and Statistics Faculty Publications and Presentations

Leaders in professional development (PD) initiatives (such as facilitators, principals, coaches) hold a great deal of power in their language, carrying the ability to manage meaning and frame experiences. Rather than working from interview data, this report addresses a gap in leadership research by examining the words used by leaders in their on-the-job interactions. We present an initial framework for capturing leadership language qualities at the macro level (framing the PD’s purpose) and micro level (rhetorical crafting in terms of metaphor usage, pronoun choice, and other language selections). Our data come from a larger project evaluating the efficacy of a …

Learning To Notice And Use Student Thinking In Undergraduate Mathematics Courses, Anna Pascoe

Dissertations, Master's Theses and Master's Reports

The goal of this study was to evaluate the outcomes of an intervention focused on developing mathematics graduate teaching assistants’ skills of noticing and effectively responding to instances of student mathematical thinking that have significant potential to further students’ learning. Four mathematics graduate teaching assistants participated in a semester-long intervention in which video of undergraduate mathematics lessons was individually analyzed and then discussed collectively with the researcher on a weekly basis. The MOST Analytic Framework (Leatham, Peterson, Stockero, & Van Zoest, 2015; Stockero, Peterson, Leatham, & Van Zoest, 2014) was introduced as a tool to aid in the analysis and …

Extending Mathematic Learning Beyond The Classroom Through Online Discussion And Reflection, Linsey Zimmerman

Graduate Research Papers

This review explores the research (2002-2015) focusing on the use of writing in the high school mathematics classroom incorporating blogs and online discussion. Thirty articles were identified and analyzed which provided information on how writing in the math classroom was developed and carried out. The research found that extending the mathematical learning through writing creates a sense of community among students, allows student reflection and application, and helps students gain a deeper understanding of a mathematical concept. Implications of the research and suggestions for future research are discussed.

Sound : The Study Of Differentiating Pitch And Volume With Preschoolers, Jennifer Lyn Miller

Graduate Research Papers

I designed an exploratory study for adapting an early elementary physics of sound science module to use in preschool. The purpose of the study was to observe and collect data regarding the use of an inquiry-based physical knowledge activity, implemented in a play-based preschool setting, and how this knowledge could assist in advancing Science, Technology, Engineering, and Mathematics (STEM) education in early childhood.

Using random sampling from a classroom of 20 students, I chose six participants between the ages of four and five. As prekindergarten children experimented with sound, I probed understanding of two of the main concepts in the …

Strengthening Early Mathematics In Early Childhood Classrooms : A Professional Development Project, Jennifer Lynn Jansen

Graduate Research Papers

This project outlines a series of professional development sessions for preschool teachers that focus on early mathematics. Each session emphasizes key mathematical content and builds teachers' understanding and positive attitudes toward mathematics. Teachers also explore how children's knowledge and skills in the content topics develops and examine examples of children at various levels of understanding and stages of learning with regard to mathematical content.

The sessions also emphasize how the mathematical content can be explored in preschool classrooms in ways that support children's foundational learning in the area of mathematics. Another element of this project is the use of site-based …

Preservice And Practicing Teacher Science Inquiry Projects: An Analysis Of Their Understanding Of The Inquiry Process, Benjamin D. Olsen

Dissertations and Theses @ UNI

Student conducted inquiry is an essential component of the Next Generation Science Standards and considered to be a core goal of teaching science methods. Teachers need to understand what student inquiry entails, to be able to successfully conduct their own inquiry investigations, and to understand this process well so as to guide original student inquiry investigations. Some suggest that, as a result of No Child Left Behind legislation, an entire generation of students have missed out on inquiry-based elementary science instruction. Research indicates that many preservice teachers find it difficult to bridge knowledge of subject matter with pedagogy – making …

The Effects Of Argumentation On Student Motivation In Mathematics, Julie Kirkpatrick

Honors Program Theses

As a future educator, I am going to need to motivate my students to learn mathematics and be engaged deeply with the material. Because mathematics is a required subject for students, mathematics teachers must employ various strategies to motivate their students. Something that has motivated me in past mathematics courses has been the chance to form arguments and defend them in class. Argumentation in mathematics classrooms has been included in the Common Core Standards for Mathematical Practice as Practice Standard 3: “Construct viable arguments and critique the reasoning of others” (National Governors Association Center for Best Practices & Council of …

Motion Virtual Manipulatives In The Elementary Math Classroom, Cole Boudreau

Honors Program Theses

An application was developed to aid in teaching core mathematical concepts to kindergarten through third grade students. This software would be available at minimal cost when compared to current alternatives, and was designed specifically with effectiveness in mind. A framework called motion virtual manipulatives was developed, allowing to the creation of a touch-based application on any flat wall or surface. The application developed implemented multiple forms of manipulatives, each designed to allow for ease-of-use. The application is planned to be tested in classrooms with the aid of a secondary application developed to analyze the use of this project’s application.

Equitable Discourse In Middle School Mathematics Classrooms: With Emphasis On Girls And The Mathematically Gifted, Merci F. Day

Honors Program Theses

Discourse is a tool used by mathematics teachers to help deepen mathematical understanding and build students’ mathematical identities. Teachers face the challenge of establishing and maintaining classroom norms that help discussions deepen mathematical understanding as well as meet the needs of all of their students. The researcher focused on what girls and the mathematically gifted need from discourse and how to create an equitable environment for all students. Girls need to be given equitable opportunities to voice their thoughts, and mathematically gifted students need to be adequately challenged, not just given more work. The researcher interviewed three teachers who employ …

Proportional Reasoning In Middle Level Mathematics Textbooks, Rebecca Holzrichter

Honors Program Theses

Since textbooks are common tools used by teachers to organize what they teach, including proportional reasoning, it would be beneficial to teachers if these materials could provide a useful framework to help students meet the Common Core State Standards for Mathematics (National Governor’s Association, 2010). Therefore the purpose of my research is to critically analyze middle school textbooks. To be able to accomplish that task I will first identify critical components of proportional reasoning. Identifying the critical components will provide a framework in which to assess the tasks in the middle level mathematics textbooks. I will then evaluate the tasks …

A Moving Imagination In Spaces Of Distress: Teacher And Student Agency In A Science Classroom, Annie Sunshine Adamian

Doctoral Dissertations

This qualitative study explored the ways in which our classroom community (students and teacher) engaged with humanizing pedagogy in a seventh grade science classroom, toward the full development (e.g. personal, social, emotional, academic) of our classroom community, and the dismantling of inequitable practices and unjust policies that we recognized in our science classroom, school and/or community while utilizing the process of teacher and student participatory action research (tsPAR) (Adamian, 2015) and Critical Race Praxis for Educational Research (CRP-Ed) (Jayakumar & Adamian, 2015).

This study examined the complexities of mutually engaging across differing positionalities while intentionally working in spaces of distress …

Training In Summarizing Notes: Effects Of Teaching Students A Self-Regulation Study Strategy In Science Learning, Michelle Mendoza Nebres

Doctoral Dissertations

The last two decades of national data assessments reveal that there has been a sharp decline in nationwide standardized test scores. International assessment data show that in 2012 a very low amount of American students were performing at proficiency or above in science literacy. Research in science literacy education suggests that students benefit most when they are self-regulated (SR) learners. Unfortunately, SR poses a challenge for many students because students lack these skills. The effects of having learned few SR strategies at an early age may lead to long term learning difficulties—preventing students from achieving academic success in college and …

Integrating Diversity Training Into Doctoral Programs In Mathematics Education, Ruthmae Sears, Tonisha B. Lane

Transformations

There exists a need to promote diversity, equity, and inclusion in mathematics education (Wilson and Franke, 2008). Being cognizant that there are few underrepresented groups that obtain doctoral degrees in mathematical sciences or mathematics education (AMS, 2014; Reys and Dossey, 2008), focused training is needed to prepare doctoral students on diversity issues that may arise in higher education and the means by to address such issues. An advance seminar course or colloquium that would be helpful to mathematics education doctoral students who seek a career position in higher education should be entitled, “Gaining a better perspective of diversity in higher …

Changing The Scholarly Sources Landscape With Geomorphology Undergraduate Students, Heidi Blackburn, Ashlee L.D. Dere

Criss Library Faculty Publications

Science is a core discipline in academia yet the focus of most undergraduate technical writing is generally on the data and results, not the literature review. The Science, Technology, Engineering, and Math (STEM) librarian and a new geology professor at the University of Nebraska at Omaha (UNO) collaborated to develop an information literacy session for students in a geomorphology class. Here we outline the background of the campus STEM initiatives and the assignment as well as the library instruction activity, learning outcomes, and assessment components. The activity improved student use of scholarly sources and we provide suggested activity modifications for …

An Investigation Into The Accessibility Of Ap Calculus, Brian Austin Dodge

Capstones, Research Projects, and Curricula

This is a mixed methods ethnographic study conducted to determine what obstacles students face when approaching AP Calculus. I focused my study on home economics, peer pressure, ELL status and home support. Overall, I found that being a student who is ELL (hereafter defined as a student who was or currently is required to take ACCESS testing) had the most negative effect of the previously listed factors. Home economics and peer pressure were inconclusive or often had no effect. Finally, having a supportive home life in the form of parents who value education, encourage goal-setting, and set high expectations had …
