Teachers' Professional Knowledge And Formative Assessment Practices: An Empirical Study From Middle School Earth Science Instruction In The Context Of An Education Improvement Community, Laura Millay
Electronic Theses and Dissertations
While there is widespread agreement that effective formative assessment supports student learning in science, the knowledge teachers need in order assess learning remains sparsely studied. In 1999, Magnusson, Krajcik, and Borko (MKB) proposed that Pedagogical Content Knowledge (PCK, Shulman 1986, 1987) is a distinct knowledge domain that synthesizes three base domains that include science subject matter, pedagogy, and context. The MKB model identified Assessment Knowledge as one of five components of PCK. Since 1999, several studies have used the MKB framework, but have left Assessment Knowledge underdefined. In 2012, Avargil, Herscovitz, and Dori proposed a revision based on empirical study, …
Exploring The Knowledge Of Algebra For Teaching., Jonathan David Watkins
Exploring The Knowledge Of Algebra For Teaching., Jonathan David Watkins
Electronic Theses and Dissertations
For the past few decades, researchers in mathematics education have been exploring the concept of pedagogical content knowledge (PCK)—or knowledge related to teaching content—and applying it to various areas of mathematics, such as algebra. Research related to teacher knowledge of algebra is critical because researchers (e.g., Hill, Rowan, & Ball, 2005) have found correlations between some types of teacher knowledge and student achievement in mathematics; students from around the world are outperforming U.S. students on international assessments of mathematics, including algebra (Organization for Economic Cooperation and Development, 2014, 2016); and algebra plays an integral role in the K-12 mathematics curriculum …
A Granular Account Of Student's Understanding Reasoning Within An Everyday And Scientific Contexts, Grace M. Gonnella
A Granular Account Of Student's Understanding Reasoning Within An Everyday And Scientific Contexts, Grace M. Gonnella
Electronic Theses and Dissertations
Teachers and educational researchers in the Maine Physical Sciences Partnership (Maine PSP) at the University of Maine identified making quality scientific arguments as a struggle for students. Not only is argumentation hard, but reasoning is the hardest component of an argument. Many frameworks have been developed to target teaching about argumentation but do not address how to teach one component of an argument in isolation. Educational practitioners encourage using everyday context to learn about arguments in the scientific context, but there is limited support in what is the best method. The first purpose of this research was to understand a …
Understanding Student Development Of Science Literacy Skills In An Undergraduate Environmental Science Course, Molly Picillo
Understanding Student Development Of Science Literacy Skills In An Undergraduate Environmental Science Course, Molly Picillo
Electronic Theses and Dissertations
Educators are expected to instill a variety of skills in their students that are necessary to be competent citizens of society. One such set of skills, science literacy skills, broadly encompass the ability of an individual to evaluate reliability of data and information and critically analyze and interpret them (Gormally Brickman, Hallar, & Armstrong, 2009). These skills are utilized in everyday decision-making and given their pertinence, there is a need for citizens to be scientifically literate. Thus, educators need tools and assessments to help students develop these skills and analyze their science literacy. The aim of this study was to …

Investigating Student Understanding Of Vector Calculus In Upper-Division Electricity And Magnetism: Construction And Determination Of Differential Element In Non-Cartesian Coordinate Systems, Benjamin Schermerhorn
Investigating Student Understanding Of Vector Calculus In Upper-Division Electricity And Magnetism: Construction And Determination Of Differential Element In Non-Cartesian Coordinate Systems, Benjamin Schermerhorn
Electronic Theses and Dissertations
Differential length, area, and volume elements appear ubiquitously over the course of upper-division electricity and magnetism (E&M), used to sum the effects of or determine expressions for electric or magnetic fields. Given the plethora of tasks with spherical and cylindrical symmetry, non-Cartesian coordinates are commonly used, which include scaling factors as coefficients for the differential terms to account for the curvature of space. Furthermore, the application to vector fields means differential lengths and areas are vector quantities. So far, little of the education research in E&M has explored student understanding and construction of the non-Cartesian differential elements used in applications …
Deciphering Climate-Driven Changes In Planktonic Diatom Communities In Lake Superior, Amy Kireta
Deciphering Climate-Driven Changes In Planktonic Diatom Communities In Lake Superior, Amy Kireta
Electronic Theses and Dissertations
Climate change is affecting lake systems throughout the world, including Lake Superior, the world’s largest lake by surface area. Climate-driven physical changes in Lake Superior are well documented, but there is still substantial uncertainty of how recent biological changes are related to climate change. This research addresses these uncertainties using a variety of approaches to understand the effects of modern climate-driven changes on Lake Superior diatom communities. First, I developed models for environmental variables related to diatom abundance using 10 years of summer monitoring data. Second, I investigated changes in fossilized diatom relative abundances before, during, and after the Medieval …
Echoes Of The Past: The Effect Of Background Experience On Far Transfer, Graham H. Hummel-Hall
Echoes Of The Past: The Effect Of Background Experience On Far Transfer, Graham H. Hummel-Hall
Electronic Theses and Dissertations
Far transfer is the application of knowledge learned in one setting to a problem in a very different setting. This multi-method study looked at far transfer in humans and whether it could be facilitated, inhibited, or remain unaffected by the number of courses or years a student at a university spent learning about the subject matter of the knowledge being transferred. Through quantitative and qualitative analysis of pretest and post-test data from an introductory undergraduate earth science course, I found that students with more physical science background experience more frequently engaged in successful and accurate transfer of physics information to …

Success Rates Of Second Semester Anatomy Students In Online And On-Ground Classes At A Community College In East Tennessee, William Sproat
Electronic Theses and Dissertations
Educators expect the number of institutions offering online courses and the number of students enrolling in these courses to increase as many students, particularly nontraditional students, discover the advantages of online content delivery. Online courses require new methods of communication between students and faculty as well as discovering new ways to build relationships, earn student trust, conduct appropriate assessment, and deliver useful course content. Many institutions—public, private, and for-profit—offer a wide variety of online coursework but faculty, employers, and the public have expressed concerns about the quality of online course content. In particular, online delivery of coursework in the natural …
Assessing Student Understanding Of Reasoning Using Argument-Based Contrast Matrices, Ethan Geheb
Assessing Student Understanding Of Reasoning Using Argument-Based Contrast Matrices, Ethan Geheb
Electronic Theses and Dissertations
There is strong national interest in increasing student proficiency in STEM, which includes the learning and practice of scientific argumentation. The codevelopment of scientific knowledge and argumentation has shown to positively influence student general understanding of argument construction, scientific knowledge and principles. Research indicates students continue to struggle with constructing complete arguments, with specific difficulty in correctly incorporating reasoning. Numerous frameworks have been developed to support student learning about argumentation. These frameworks contain common teaching strategies for introducing and teaching reasoning within the context of a science classroom. However, these strategies do not specifically target student struggle with using reasoning, …
A Phenomenological Study Of The Experiences Of Successful Women In Science Fields, Jonathan Hall
A Phenomenological Study Of The Experiences Of Successful Women In Science Fields, Jonathan Hall
Electronic Theses and Dissertations
Girls and women face several forms of gender-based biases and discrimination in the science community. These issues create difficult circumstances for them to develop positive science identities. Since these difficult circumstances exist, science education and sociology researchers have used a deficit model to learn about their experiences, achievements, and attitudes. Understanding the experiences of successful women in science offers insight into how women can navigate the challenges presented by the science community and how science educators can support them. However, research studies that explore the experiences of successful women in science are scant. Therefore, the objective of this study was …
Middle Grades Science In Florida: A Comparison Of Student Achievement In Comprehensive And Subject-Specific Science Courses 2013-2017, Kenneth Moore
Middle Grades Science In Florida: A Comparison Of Student Achievement In Comprehensive And Subject-Specific Science Courses 2013-2017, Kenneth Moore
Electronic Theses and Dissertations
As with U.S. student achievement on national and international science assessments, Florida's 8th grade student achievement on the 2013–2017 8th grade Florida Comprehensive Assessment Test (FCAT) 2.0 Science/Statewide Science Assessment (SSA) was stagnant. To break this stagnation, many Florida school districts have changed middle grades science course offerings from traditional, subject-specific, discipline-based, layered, or field-specific science courses to comprehensive, integrated, spiraled, interdisciplinary, multidisciplinary, thematic, or general science courses. There was a lack of research showing if either type of science course improved student achievement on standardized science assessments. Controlling for school district student population, low socio-economic status (SES) student percentage, …
A Multiple Case Study Exploring The Relationship Between Engagement In Model-Eliciting Activities And Pre-Service Secondary Mathematics Teachers' Mathematical Knowledge For Teaching Algebra, Aline Abassian
Electronic Theses and Dissertations
The goal of this research study was to explore the nature of the relationship between engagement in model-eliciting activities (MEAs) and pre-service secondary mathematics teachers' (PSMTs') mathematical knowledge for teaching (MKT) algebra. The data collection took place in an undergraduate mathematics education content course for secondary mathematics education majors. In this multiple case study, PSMTs were given a Learning Mathematics for Teaching (LMT) pre-assessment designed to measure their MKT algebra, and based on those results, three participants were selected with varying levels of knowledge. This was done to ensure varied cases were represented in order to be able to examine …
An Examination Of The Algebra 1 Achievement Of Black And Hispanic Student Participants In A Large Urban School District's Mathematics Intervention Program, Elethia Bronson
Electronic Theses and Dissertations
The mathematics achievement gap between Black and White as well as Hispanic and White students has been well documented nationwide and in the school district of study. Much has been written in observance of the achievement gap, yet markedly less research has focused on practices and interventions that have improved mathematics performance for Black and Hispanic students. Consequently, this study examined the Algebra 1 achievement (indicated by student scale scores on the Florida Standards Assessments Algebra 1 End-of-Course exam) of Black and Hispanic students participating in a mathematics intervention program as compared to the Algebra 1 achievement of their similar …
