Development Of Middle School Teachers' Knowledge And Pedagogy Of Justification: Three Studies Linking Teacher Conceptions, Teacher Practice, And Student Learning, Carolyn Mccaffrey James Jun 2016

Development Of Middle School Teachers' Knowledge And Pedagogy Of Justification: Three Studies Linking Teacher Conceptions, Teacher Practice, And Student Learning, Carolyn Mccaffrey James

Dissertations and Theses

Justification and argumentation have been identified as important mathematical practices; however, little work has been done to understand the knowledge and pedagogy teachers need to support students in these ambitious practices. Data for this research was drawn from the Justification and Argumentation: Growing Understanding in Algebraic Reasoning (JAGUAR) project. JAGUAR was a multi-year research and professional development project in which 12 middle school math teachers and a group of researchers explored the knowledge and pedagogy needed to support student justifications. This dissertation consists of three case study analyses. The first paper describes the development of teacher conceptions of justification, including …


Learning Through Nature: A Study Of A Next Generation Science Standards Based Teacher Workshop That Blends Outdoor Learning Experiences With Formal Science, Ashley Fanning Mar 2016

Learning Through Nature: A Study Of A Next Generation Science Standards Based Teacher Workshop That Blends Outdoor Learning Experiences With Formal Science, Ashley Fanning

Dissertations and Theses

Many teachers lack the confidence and knowledge to transition their classroom science lessons to an outdoor setting. Very few teacher professional development (PD) programs focus on improving teachers' self-efficacy and pedagogical content knowledge (PCK) that is needed to enhance their science curriculum with outdoor lessons. This study examined an exception: The Connect2Science workshops, which provided elementary teachers the opportunity to experience nature-based science lessons. My research question for this study is: In what ways does a professional development workshop focused around the Next Generation Science Standards influence teachers': a) self-efficacy in teaching science outdoors and b) science pedagogical content knowledge? …


Tryon Trekkers: An Evaluation Of A Stem Based Afterschool Program For At-Risk Youth, Chessa Eckels Anderson Mar 2016

Tryon Trekkers: An Evaluation Of A Stem Based Afterschool Program For At-Risk Youth, Chessa Eckels Anderson

Dissertations and Theses

This study contributed to the body of research that supports a holistic model of afterschool learning through the design of an afterschool intervention that benefits elementary school students of low socioeconomic status. This qualitative study evaluated a science focused afterschool curriculum that was designed using principles from Risk and Resiliency Theory, academic motivation theories, science core ideas from the Next Generation Science Standards, and used environmental education philosophy. The research question of this study is: how does an outdoor and STEM based afterschool program impact at-risk students' self-efficacy, belonging and engagement and ability to apply conceptual knowledge of environmental science …


Growing Stem Education On The Playground: A Case Study Of The Factors That Influence Teachers’ Use Of School Gardens, Megan Poole Mar 2016

Growing Stem Education On The Playground: A Case Study Of The Factors That Influence Teachers’ Use Of School Gardens, Megan Poole

Dissertations and Theses

School gardens can have a profound, positive influence on a student's academic achievement, social skills, and attitudinal orientation. Despite these clear benefits, the use of school gardens as an instructional medium is not as prevalent as would be expected. There are several types of obstacles that can prevent teachers from using school gardens, including facets of time, support, and knowledge-based challenges. This multiple case study employs a mixed methods design to uncover factors that influence primary school teachers' decisions to utilize a school garden in their STEM curriculum. The goals of this study were to determine the types of benefits …


Engineering Professional Development: Elementary Teachers' Self-Efficacy And Sources Of Self-Efficacy, Donna Louise Webb Jun 2015

Engineering Professional Development: Elementary Teachers' Self-Efficacy And Sources Of Self-Efficacy, Donna Louise Webb

Dissertations and Theses

Currently, STEM (science, technology, engineering, and mathematics) is a popular buzz word in P -12 education as it represents a means to advance American competitiveness in the global economy. Proponents of the engineering component of STEM advocate additional benefits in teaching engineering, such as its capacity to engage students in collaboration, and to apply critical thinking, systems thinking, negotiation, and communication skills to solve real-life contextual problems. Establishing a strong foundation of engineering knowledge at a young age will provide students with internal motivation as it taps into their curiosity toward how things work, and it also prepares them for …


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 Aug 2014

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 …


Prospective Elementary Mathematics Teacher Content Knowledge: An Introduction, Christine Browning, Eva Thanheiser, Alden Edson, Patrick M. Kimani, Dana Olanoff, Jennifer M. Tobias, Ian Whitacre Jan 2014

Prospective Elementary Mathematics Teacher Content Knowledge: An Introduction, Christine Browning, Eva Thanheiser, Alden Edson, Patrick M. Kimani, Dana Olanoff, Jennifer M. Tobias, Ian Whitacre

Mathematics and Statistics Faculty Publications and Presentations

This Special Issue on the mathematical content knowledge of prospective elementary teachers (PTs) provides summaries of the extant peer-­‐reviewed research literature from 1978 to 2012 on PTs’ content knowledge across several mathematical topics, specifically whole number and operations, fractions, decimals, geometry and measurement, and algebra. Each topic-­‐specific summary of the literature is presented in a self-­‐contained paper, written by a subgroup of a larger Working Group that has collaborated across several years, resulting in this Special Issue sharing the final work. The authors hope this summative look at prospective teacher content knowledge will be of interest to the mathematics education …


Investigating Further Preservice Teachers’ Conceptions Of Multidigit Whole Numbers: Refining A Framework, Eva Thanheiser Jan 2010

Investigating Further Preservice Teachers’ Conceptions Of Multidigit Whole Numbers: Refining A Framework, Eva Thanheiser

Mathematics and Statistics Faculty Publications and Presentations

This study was designed to investigate preservice elementary school teachers’ (PSTs’) responses to written standard place-value-operation tasks (addition and subtraction). Previous research established that PSTs can often perform but not explain algorithms and provided a four-category framework for PSTs’ conceptions, two correct and two incorrect. Previous findings are replicated for PSTs toward the end of their college careers, and two conceptions are further analyzed to yield three categories of incorrect views of regrouped digits: (a) consistently as 1 value (all as 1 or all as 10), (b) consistently within but not across contexts (i.e., all as 10 in addition but …
