Investigating The Effectiveness Of A Professional Development Program For Secondary Physics Teachers, Meghan Reynolds

Dissertations and Theses @ UNI

National studies have exposed a shortage of highly-qualified high school physics teachers, with over 25% of physics teaching vacancies in Iowa being very difficult to fill or unable to be filled. In an effort to improve the nation’s education system, there have been broad changes in the framework of what constitutes high-quality teaching which supports a trend away from traditional, lecture-based teaching methods and towards interactive, student-centered methods. This study analyzed the impact of a professional development program that aimed to prepare more high-quality high school physics teachers by building physics content knowledge through the use of reformed teaching techniques …

Culturally Relevant Pedagogy: Secondary Mathematics In An Urban Classroom, Julia Glissmann North

Honors Program Theses

Research and test scores have shown that African-American, Latino, Native American, and other minority students are underachieving in secondary mathematics. This is concerning not only to school personnel – who are under pressure to have students perform well on standardized tests – but also to the future of the country. When teachers adopt a culturally relevant pedagogy, diverse students will have a better opportunity to learn and retain mathematical content. When academic content is taught in a culturally relevant way, students are able to retain the information, improve their performance in school, and become more informed participants in society. Through …

Rehearsal And Enactment For Teaching In Urban School Settings: A Qualitative Study Investigating The Connections Between A Math Methods Course And Fieldwork, Rajeev Virmani

Doctoral Dissertations

In this dissertation, I studied teacher education reform efforts aimed at improving the preparation of preservice teachers through the use of rehearsals in a math methods class. As many experts in the field of teacher education call for curricula in which preservice teachers learn from and in practice, I investigated a type of pedagogy called rehearsals within a practice-based teacher education setting that may afford preservice teachers with the initial preparation needed to become effective teachers.

In this qualitative study, I examined how three preservice teachers and math methods instructors rehearse the high leverage practice of leading a whole-class discussion. …

Integrating Universal Design And Response To Intervention In Methods Courses For General Education Mathematics Teachers, Kelley E. Buchheister, Christa Jackson, Cynthia Taylor

Department of Child, Youth, and Family Studies: Faculty Publications

Traditionally, teacher education programs have placed little emphasis on preparing mathematics teachers to work with students who struggle in mathematics. Therefore, it is crucial that mathematics teacher educators explicitly prepare prospective teachers to instruct students who struggle with mathematics by providing strategies and practices that specifically address their needs. In this study, we describe the principles of Universal Design for Learning and Response to Intervention. More specifically, we discuss how one Mathematics Teacher Educator uses these frame works in her mathematics methods course to help prospective teachers become cognizant of early interventions and effective strategies that can be implemented to …

An Investigation Of Subtraction Algorithms From The 18th And 19th Centuries, Nicole Enzinger

Faculty Publications - College of Education

How do you subtract? What is your algorithm of choice? The most common subtraction algorithm in the United States today is the decomposition algorithm. While other algorithms exist and are possibly utilized, no other algorithm dominates the contemporary curriculum, classrooms, and pencils of children in the U.S. more so than the decomposition algorithm. Subtraction is one of the fundamental building blocks of arithmetic. Looking to the past and exploring the history of subtraction algorithms can help us glean knowledge of the intended and possibly implemented curricula in past eras. In this paper, special attention will be given to 18th and …

Methods For Multimodal Analysis And Representation Of Teaching-Learning Interactions In Primary Science Lessons Captured On Video, Mark W. Hackling, Karen J. Murcia, Khadeeja Ibrahim-Didi, Susan M. Hill

Research outputs 2014 to 2021

Video-based classroom research is opening-up exciting new insights into how teachers generate productive opportunities for student engagement in quality learning, reasoning and the development of their scientific literacy. The significant role played by multimodal representations in learning and teaching becomes evident through the medium of video and its analysis. Classroom research that is framed from social constructivist, sociocultural, activity theory and social semiotic perspectives highlights the social interactions involving multimodal representations which are used to communicate science ideas and also act as semiotic resources for meaning making. Social and cognitive processes of co-constructing meaning are mediated by talk, embodied representations …

Teaching For Students' Confident Transition From Number To Algebra, Christina Lang Lee

Theses: Doctorates and Masters

The adoption by all states and territories of the national curriculum by 2013 saw students in schools across the country taught introductory algebraic concepts from Year Five. In the twenty first century the need to be algebraically competent has become a necessity much as computation was in the previous centuries.

The Researcher has found from experience that students who have struggled with number and number operations will then most probably make poor progress in their study of algebra. The transition from number to algebra requires a robust understanding of number and number operations

This study investigated the balance of instructional …

Paper 4: Do You See What I See? Deepening Teachers’ Understanding Of Linear Equations Through Student Interviews, Tamara Pearson, Kelli Nipper, Catherine Matos

Georgia Association of Mathematics Teacher Educators (GAMTE) Annual Conference (2007-2019)

Many teachers have trouble transitioning their students between natural recursive thinking about the data and algebraic notation for representing linear functions (Zazkis & Liljedahl, 2002).

In this study, we interviewed eighteen middle school students to see how they used prior instruction to think about a geometric pattern and construct its corresponding linear equation. All students

were given the same task to complete and were questioned about their thinking during the interview.

We found that the recording of pattern recognition plays a substantial part in helping students recognize and write explicit patterns. By having students decompose the total perimeter into how …

Paper 1: A Proposed Pedagogical Approach For Preparing Teacher Candidates To Incorporate (Academic) Language, Woong Lim, Lynn Stallings

Georgia Association of Mathematics Teacher Educators (GAMTE) Annual Conference (2007-2019)

The edTPA is a performance-based assessment that aims to measure teacher candidates’ readiness for teaching. Beginning in the fall of 2015, this assessment will be a mandatory requirement for those seeking certification in Georgia. General agreement exists in the field of education about the basic knowledge and skills essential for beginning teachers to demonstrate in classroom teaching. Does edTPA measure the knowledge and skills essential for beginning mathematics teachers in particular? Assuming that edTPA can successfully measure that knowledge and skills for beginning teachers, the use of the assessment could be valuable.

One of the critical components of edTPA is …

Paper 3: Differences In Beliefs Across A Series Of Four Mathematics Content Courses, Susanna Molitoris Miller, Caitlin Walkey

Georgia Association of Mathematics Teacher Educators (GAMTE) Annual Conference (2007-2019)

College students often ask questions such as, “Why do I have to take this class? Is there a point to it?” For Early Childhood Education (ECE) majors these questions may often take on a slightly different form, wondering, “How can I incorporate this information into my classroom?” or “Do I understand this well enough to teach this to my students?” It is especially important for pre- service teachers to feel confident working with the mathematical content that they are learning and for them to believe that they can successfully teach that same information to a group of students. Swackhamer, Koellner, …

Paper 6: A Mathematics Teacher’S Journey Of Identity Construction And Change, Anthony B. Stinson

Georgia Association of Mathematics Teacher Educators (GAMTE) Annual Conference (2007-2019)

Despite some gains, improving mathematics instruction remains an area of concern in the United States. The implementation of the Common Core Standards and the challenge of teaching the 21st Century student require mathematics teachers to examine their pedagogy to determine if they need to change or improve their practices. This paper provides a personal account of my journey when determining my identity as a mathematics teacher and how constructing my identity helped in changing and improving my practices as a mathematics teacher. The study was done using autoethnography, a burgeoning research method, and identity theory. This study has the goals …

There is widespread agreement that science, technology, engineering, and mathematics programs should provide undergraduates with research experience. Practical issues and limited resources, however, make this a challenge. We have developed a bioinformatics project that provides a course-based research experience for students at a diverse group of schools and offers the opportunity to tailor this experience to local curriculum and institution-specific student needs. We assessed both attitude and knowledge gains, looking for insights into how students respond given this wide range of curricular and institutional variables. While different approaches all appear to result in learning gains, we find that a significant …

Teaching Undergraduates How To Analyze, Ryan Andrew Nivens, Rosalind Raymond Gann

ETSU Faculty Works

Analysis is typically listed in taxonomies of higher order thinking. Academics consider these taxonomies worthwhile, but they are hard to teach and we are apt to ignore them. Today higher education is criticized for “dumbing down” curriculum or lowering standards. To rectify this, many policies at the state or national level are requiring higher education institutions to change. In K-12 education, Race to the Top and Common Core requirements are placing new demands on K-12 teacher preparation, which include evaluation of the analysis skills of pre-service teachers. But professors do not always view their disciplines as the proper place for …

Encouraging Literacy And Mathematics Achievement Through Study Of Real Estate, Ryan Andrew Nivens, Lori T. Meier, Karin J. Keith, Erin E. Doran, Edward J. Dwyer

ETSU Faculty Works

The era of high stakes testing often puts pressure on teachers and administrators to deemphasize creative activities not perceived as directly related to improving test scores. Alternatively, the authors propose that using environmental text is essential for encouraging overall learning competencies in general and reading/writing/ and mathematical achievement in particular. The authors propose that using real estate booklets can be helpful in generating learning activities in literacy, social studies, and mathematics. In addition, integrating music and art comfortably accompanies strategies presented. Real estate booklets are colorful, rich in content, and readily available at no expense.

On The Effect Of Virtual Reality On Student Understanding Of And Interest In Physics, Isaac D. Crouch

Dissertations, Master's Theses and Master's Reports - Open

This study investigated the effect that the video game Portal 2 had on students understanding of Newton’s Laws and their attitudes towards learning science during a two-week afterschool program at a science museum. Using a pre/posttest and survey design, along with instructor observations, the results showed a statistically relevant increase in understanding of Newton’s Laws (p=.02<.05) but did not measure a relevant change in attitude scores. The data and observations suggest that future research should pay attention to non-educational aspects of video games, be careful about the amount of time students spend in the game, and encourage positive relationships with game developers.

An African-Centered Approach To Land Education, Salvotore Engel-Dimauro, Karanja Keita Carroll

Publications and Research

Approaches to environmental education which are engaging with place and critical pedagogy have not yet broadly engaged with the African world and insights from Africana Studies and Geography. An African-centered approach facilitates people's reconnection to places and ecosystems in ways that do not reduce places to objects of conquest and things to be exploited for profitability and individual gain. Such an approach offers effective critiques of settler coloniser perspectives on the environment and deeper understandings of the relationship between worldview and ecologically sensitised education. Through examples from Africana Studies and Geography, this article provides an introduction to how an African-centered …

Mentor Preparation: A Qualitative Study Of Stem Master Teacher Professional Development, Heather Lynn Click-Cuellar

Open Access Theses & Dissertations

The No Child Left Behind Act of 2001 has required districts to staff all classrooms with highly qualified teachers. Yet, retaining certified teachers in the profession has been a national concern, especially among new teachers who leave at alarming rates within their first three years. This comes at a heavy cost to districts financially and in trying to maintain highly qualified status, but also to the continuity and effective education of students. Mentoring has been identified by many researchers as a plausible solution to reducing attrition rates for beginning teachers.

In this Dissertation, I conducted qualitative research to explore and …
