Learning To See The Forest For The Corn: Establishing Sense Of Place And Community In A Field-Based Ecology Course For Pre-Service Educators, Michelle Edgcomb Friday

Theses and Dissertations

In this dissertation grounded theory techniques were used to characterize pre-service educators’ experiences in a semester-long, field-based ecology course. Through participation in a citizen science project, participants formed a community of practice that extended their conceptions of themselves as ecology students and scientists. Extended field experiences in a variety of local ecosystems contributed to the development of a sense of place. Paired fieldwork with lecture aided their developing ecological literacy and their understanding of place-based pedagogy. All of these combined to support their growing understanding of their role in field-based ecology education. Lack of background in ecology and ecology pedagogy …

An Examination Of How One University Is Preparing Elementary And Middle Level Education Majors For Common Core Mathematics, Michelle Elizabeth Schwartze

Theses and Dissertations

In 2010 the Common Core State Standards (CCSS) for mathematics and English Language Arts were introduced into K – 12 classrooms (Common Core State Standards Initiative, 2015b). The standards for mathematics focus on having students demonstrate and explain understanding more than the standards have in the past (Burns, 2013). McCallum (2011) divides the eight Standards for Mathematical Practice into four main themes: reasoning and explaining, modeling and using tools, seeing structure and generalizing, and overarching habits of mind of a productive mathematical thinker. These four themes encompass what a mathematics classroom should look like when utilizing the CCSS for mathematics. …

Secondary Mathematics Teachers' Learning Through Practice: The Case Of Rudy, Theodore John Rupnow

Theses and Dissertations

In this study I investigated teachers’ learning through practice. Teachers learn in teacher preparation programs and in professional development, but the most personal learning occurs in practice. Teachers spend much of their time isolated from colleagues, participating in classroom communities instead of professional communities. If teacher educators want to understand the potential for learning in the space where teachers spend much of their time it is necessary to investigate the learning that is occurring in classroom practice. To pursue this end, I explored one secondary mathematics teacher’s learning in practice. I observed and video-recorded this teacher’s classroom practice for one …

An Intervention Study Aimed At Enhancing Seventh-Grade Students’ Development Of The Concept Of A Variable, Sinan Kanbir

Theses and Dissertations

Thirty-two seventh-grade students attending a public middle school in a rural district in a midwestern state of the United States of America participated in a mixed-method intervention study aimed at enhancing student understandings of the algebraic concept of a variable, especially in relation to structure and modeling. Participating students were randomly allocated to two class groups, with one class initially being taught by Mr. X and the other by Mr. Y, who had both participated in professional development sessions led by two senior mathematics educators. Mr. X initially led one of the class groups in seven sessions on algebraic structures …

The Assessment Of Scientific Reasoning Skills Of High School Science Students: A Standardized Assessment Instrument, Shane Hanson

Theses and Dissertations

The main goal of science education has been achieving scientific literacy. However, this has been no easy task considering that scientific literacy has many definitions that involve a plethora of activities. This means that assessing the topic becomes quite challenging, especially if this is done with some sort of overarching instrument. Fortunately, Shamos (1995) has characterized the many dimensions of scientific literacy into three levels. These dimensions can then be assessed individually, making the task of assessment less overwhelming. The highest level, true scientific literacy contains dimensions that are discussed in this study, which already have individual assessments. Wenning's Nature …

The Effects Of An Undergraduate Algebra Course On Prospective Middle School Teachers' Understanding Of Functions, Especially Quadratic Functions, Jonathan Taniola Duarte

Theses and Dissertations

Although current reform movements have stressed the importance of developing prospective middle school mathematics teachers' subject matter knowledge and understandings, there is a dearth of research studies with regard to prospective middle school teachers' confidence and knowledge with respect to quadratic functions. This study was intended to fill this void. It generated information on prospective teachers' knowledge of quadratic functions as well as of their confidence to answer questions involving quadratic equations and multiple representations of functions.

The study employed a multiple-perspectives design, with data being collected from different vantage points - documents, pre- and post-teaching tests, artifacts, interviews, classroom …

Examining Middle School Students' Statistical Thinking While Working In A Technological Environment, Melissa Arnold Scranton

Theses and Dissertations

Examining Middle School Students' Statistical Thinking

While Working in a Technological Environment

Melissa Arnold Scranton

The purpose of this study was to gain a better understanding of how students think in a technological environment. This was accomplished by exploring the differences in the thinking of students while they worked in a technological environment and comparing this to their work in a paper and pencil environment. The software program TinkerPlots: Dynamic Data Exploration (Konold & Miller, 2005), a construction tool that middle school students use for data analysis was the technological environment. In both environments, types of critical, creative, and statistical …
