The uses of new technologies during mathematics instruction are essential for maintaining opportunities for students to gain better understanding of the content and become digital learners in the information age. Although scholars found technology integration is helpful in improving students’ mathematics achievement, the role of teachers’ preparedness for technology integration remains critical.

Technology professional development and self-efficacy are two major factors impacting teachers’ successful integration of instructional technologies. The purpose of this study was to provide a more in-depth look into (i) mathematics teachers technology uses during direct instruction, dialogic instruction, and assessment; (ii) the relationship between various types of ...


Pre-Service Elementary Teachers' Use Of Spatial Diagrams: Investigations Of Unbounded Shearing On Solid Figures, Camden G. Bock Dec 2019

Pre-Service Elementary Teachers' Use Of Spatial Diagrams: Investigations Of Unbounded Shearing On Solid Figures, Camden G. Bock

Electronic Theses and Dissertations

Mithala and Balacheff (2019) describe three difficulties with two-dimensional representations of three-dimensional geometrical objects: “it is no longer possible to confuse the representation with the object itself,” visually observed relationships can be misleading, and analysis of the representation requires the use of lower-dimensional theoretical properties. Despite these difficulties, students are routinely expected to learn about three-dimensional figures through interacting with two-dimensional inscriptions. Three-dimensional alternatives include diagrams realized through various spatial inscriptions (e.g., Dimmel & Bock, 2019; Gecu-Parmaksiz & Delialioglu, 2019; Lai, McMahan, Kitagawa & Connolly, 2016; Ng and Sinclair, 2018). Such diagrams are three-dimensional in the sense that they occupy real (e.g., 3D pen drawings) or rendered ...


The High School To First-Year College Instructional Transition: An Investigation Of The Predictions And Perceptions Of Stem Students, Emma Toth May 2019

The High School To First-Year College Instructional Transition: An Investigation Of The Predictions And Perceptions Of Stem Students, Emma Toth

Electronic Theses and Dissertations

Recent national reports have cited ongoing issues in undergraduate science, technology, engineering, and mathematics (STEM) education. Fewer than half of first-year undergraduate students who start in STEM fields graduate with a STEM degree six years later. Most of this attrition occurs between the first and second year of college, and students often cite instructional practices used in introductory college courses as a prominent reason for leaving. Furthermore, students from backgrounds that are underrepresented in STEM fields, including first-generation college students, leave STEM majors at higher rates than their classmates. Recent data show that the instructional practices used in introductory college ...


Learning Science: Physical And Life Sciences In Curricula Across U.S. Schools Of Nursing, Valerie C. Sauda May 2019

Learning Science: Physical And Life Sciences In Curricula Across U.S. Schools Of Nursing, Valerie C. Sauda

Electronic Theses and Dissertations

Nursing educators are being challenged to provide curriculum that meets the changing healthcare environment and demand for creative, innovative nurses to assist in transforming healthcare into the future (Benner, Sutphen, Leonard, & Day, 2010; Institute Of Medicine, 2011). The liberal education provided within a baccalaureate of science in nursing (BSN) degree program provides a diversity of courses within the curriculum, including courses in the natural, physical, mathematical, and social sciences (American Association of Colleges of Nursing [AACN], 2008). Although nursing programs have included science courses in curriculum since the early 1900s (Nutting & Dock, 1907), there is lack of nursing educational research as to ...

The purpose of this study is two-fold: 1) to investigate how 9th grade students in an Earth Science class use quantitative reasoning (QR) skills when constructing evidence-based scientific explanations during Data Story assignments and 2) to provide teachers with supports to incorporate Data Stories into their ...


Seeing The World Differently. An Exploration Of A Professional Development Model Bridging Science And Lay Cultures, Michael D. Garrett May 2019

Seeing The World Differently. An Exploration Of A Professional Development Model Bridging Science And Lay Cultures, Michael D. Garrett

Electronic Theses and Dissertations

This study explores the rationale, efficacy, and social validity of a professional development model designed to move elementary school science activities closer to the practices of working scientists as required by the United States’ “Next Generation Science Standards.” The model is culturally sensitive and aims to create experiences with high subjective task value. The formal theory of change uses scaffolding, Piagetian agency, and Vygotskian learning opportunities to argue that culturally familiar representational tasks in culturally natural intersubjective contexts can lead to work prototypical of scientific modeling under particular facilitation conditions: when participants (a) are allowed free use of their cognitive ...

Teachers' Professional Knowledge And Formative Assessment Practices: An Empirical Study From Middle School Earth Science Instruction In The Context Of An Educational Improved Community, Laura Millay Dec 2018

Teachers' Professional Knowledge And Formative Assessment Practices: An Empirical Study From Middle School Earth Science Instruction In The Context Of An Educational Improved 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 Dec 2018

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 in the U.S. (National Council of Teachers of Mathematics, 2000). Given this ...


A Granular Account Of Student's Understanding Reasoning Within An Everyday And Scientific Contexts, Grace M. Gonnella Aug 2018

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 Aug 2018

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 develop science literacy interventions that could be easily incorporated into college curricula, providing instructors with exemplars of classroom interventions with the intent to improve students’ science literacy skills. Therefore, the broad research question for this investigation was: How do science literacy interventions impact student proficiency in science literacy skills in college general education courses? I measured effectiveness of the interventions using the Test of Science Literacy Skills (TOSLS, Gormally Brickman, & Lutz, 2012) pre- and post-survey scores, as well as student feedback from pre- and post-survey, follow-up interviews. The TOSLS surveys were given as part of a participation grade to students in a general education undergraduate college course (n = 148). A subset of students volunteered to be interviewed regarding specific questions from the TOSLS survey, after both the pre-survey (n = 12) and the post-survey (n = 5), to further investigate student understanding and interpretation. Interventions were designed by modifying previous assignments from earlier years’ offerings of the class and were conducted both during class and outside of class as homework extensions. These interventions were created by evaluating scores and interviews on the TOSLS survey deployed as a pilot study in a previous semester of the undergraduate course. Based on these pilot data, four survey questions encompassing different science literacy skills of particular difficulty were targeted for intervention. The interventions were: (1) An interactive clicker-based lesson involving graph selection methods; (2) Data summits involving graph interpretation and source evaluation; and (3) A role-play after which students discussed sources of bias.

Although the results indicated no statistically significant changes in the average scores between the pre-survey and post-survey (t test, p = 0.82, α = 0.05), interviewed students recalled ...

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 May 2018

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 of vector calculus. This study contributes to the research base on the learning and teaching of these quantities.

Following course observations of junior-level E&M, targeted investigations were conducted to categorize student understanding of the properties of these differentials as they are constructed in a coordinate system without a physics context and as they are determined within common physics tasks. In general, students did not have a strong understanding of the geometry of non-Cartesian coordinate systems. However, students who were able to construct differential area and volume elements as a product of differential lengths within a given coordinate system were more successful when applying vector calculus. The results of this study were used to develop preliminary instructional resources to aid in the teaching of this material.

Lastly, this dissertation presents a theoretical model developed within the context of this study to describe students’ construction and interpretation of equations. The model joins existing theoretical frameworks: symbolic forms, used to describe students’ representational understanding of the structure of the constructed equation; and conceptual blending, which has been used to describe the ways in which students combine mathematics and physics knowledge when problem solving. In addition to providing a coherent picture for how the students in this study connect contextual information to symbolic representations, this model is broadly applicable as an analytical lens and allows for a detailed reinterpretation of similar analyses using these frameworks.


Deciphering Climate-Driven Changes In Planktonic Diatom Communities In Lake Superior, Amy Kireta May 2018

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 ...


Echoes Of The Past: The Effect Of Background Experience On Far Transfer, Graham H. Hummel-Hall May 2018

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 ...

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 ...

Contrast Dependent Knowledge Development In Contrast Supported Scientific Observation, Maura B. Foley Aug 2017

Contrast Dependent Knowledge Development In Contrast Supported Scientific Observation, Maura B. Foley

Electronic Theses and Dissertations

Knowledge of contrasts between phenomena can influence how people think and reason about them, so learning contrasts is important in school science. Building knowledge through a process of construction is a common framework through which school science is taught. However, telling phenomena apart through differentiation also plays an important role in learning and may be underused as a teaching framework. An effective way to learn contrasts is to use them to perceptually differentiate similar-looking phenomena presented side-by-side. However, little is known about the persistence/usefulness of knowledge generated during perceptual differentiation over short periods of time and its usage in ...


Using Contrasting Cases To Build Metacognitive Knowledge About The Impact Of Salient Distracting Features In Physics Problems, Thanh K. Le Aug 2017

Using Contrasting Cases To Build Metacognitive Knowledge About The Impact Of Salient Distracting Features In Physics Problems, Thanh K. Le

Electronic Theses and Dissertations

Student reasoning on physics problems is often context dependent. A possible explanation is that salient distracting features (SDFs) in physics problems may cue students’ “spontaneous” reasoning. This cued reasoning is often accepted without question, even though it may be unproductive and may even preclude the use of relevant knowledge. One possible approach to address such reasoning difficulties is to strengthen students’ metacognitive skills, particularly their metacognitive knowledge. While metacognitive knowledge plays an important role in facilitating effective regulation, little is known about how to build student metacognitive knowledge. This dissertation explores the use of contrasting cases (e.g., a number ...


Investigating Student Mental Models At The Intersection Of Mathematics And Physical Reasoning In Physics, Savannah E. Lodge-Scharff Aug 2017

Investigating Student Mental Models At The Intersection Of Mathematics And Physical Reasoning In Physics, Savannah E. Lodge-Scharff

Electronic Theses and Dissertations

A significant challenge in learning science and mathematics is coordinating different types of mental models, such as mathematical and physical mental models, that represent different aspects of a given phenomenon. This challenge is illustrated in the present study, in which we observed a small number of college students reasoning about forces as both physical and mathematical quantities as they reasoned about a physical system. Using video analysis of the students’ gesture and as they reasoned qualitatively and mathematically about the system, we documented the construction and coordination of participants’ mental models. We found that participants constructed mathematical mental models as ...
