Conceptualization And Perceptions Of Student Preparedness In Quantitative Reasoning Among Introductory Biology Faculty, Ann Cleveland

Electronic Theses and Dissertations

Quantitative reasoning (QR) is a crucial competency as undergraduate biology students complete their academic program and enter a workforce increasingly reliant on analyses of vast and complex data sets. The need to prepare biology majors for the 21^st century workforce was cited in Vision and Change: a Call to Action (American Association for the Advancement of Science [AAAS], 2011). The Vision and Change document also advocated for curriculum reform to incorporate QR instruction in undergraduate biology programs. Biology education researchers answered this call with a wealth of research examining undergraduate QR competencies, barriers and challenges to QR learning in …

An Investigation Of The Instructional Norms Of Mathematical Communication When Students Present Geometry Proofs At The Board, Bukola T. Ake

Electronic Theses and Dissertations

Expert mathematical communication is a synthesis of speaking, writing, diagramming, and gesturing. What opportunities are there for secondary mathematics students to learn the discipline-specific ways in which these modalities can be combined to communicate proofs? In an initial effort to investigate this question, Dimmel and Herbst (2020) conducted a multimedia survey experiment to test a hypothesis about how secondary mathematics teachers expect students to communicate when presenting proofs at the board in secondary geometry classrooms. Their hypothesis, based on an analysis of episodes of instruction from a small sample of secondary geometry classrooms, was that teachers expected student presentations of …

Borderline Grading Decisions: The Factors That Influence The Choices Of High School Physical Science Teachers, Kate Roberts

Electronic Theses and Dissertations

Teachers consider many different kinds of factors in determining student grades. They use a mix of achievement and non-achievement factors in grading decisions, to the criticism of educational measurement experts (Brookhart, 1991; Brookhart, 1993; Frary et al., 1993; Popham, 2009). The factors that influence this decision making are particularly salient when teachers consider borderline grades and make decisions about raising, holding, or lowering marks. The purpose of this phenomenological study was to explore the experiences and self-reported practices of high school physical science teachers’ decision making about borderline grades. Through a series of two semi-structured interviews, twelve participants described the …

Investigating The Teaching And Assessment Experiences Of Maine Secondary Science Teachers During The Covid-19 Lockdown, Anupam Raj

Electronic Theses and Dissertations

In March 2020, an unexpected event changed the educational systems throughout the world. In the United States, the COVID-19 pandemic caused public places to close down, including schools. To continue education, schools in Maine went online. This study describes how Maine secondary science teachers taught and assessed their students while teaching remotely for the first time during the lockdown. It does so by investigating teachers’ perspectives about the impact on their students, how they handled the issue of equity, their new priorities and expectations, their teaching and assessment challenges, and their successful strategies during the initial phase of the lockdown. …

Investigating Student Science Identity In A Middle School Social Studies Classroom, Hazel Cashman

Electronic Theses and Dissertations

Many science identity researchers theorize identity as a process of authoring and re-authoring oneself while being recognized by others, and therefore theorize science identity as negotiated (for example, see Avraamidou, 2019 and Calabrese-Barton et al., 2013). It is widely accepted that recognition by others shapes students’ negotiations of science identity (Carlone and Johnson, 2007). Few studies, however, have focused heavily on the role that students’ self-recognition plays in the science identity negotiation process. A large body of research also exists on students’ ideas about science (see Lederman, 1992), yet that research has not frequently intersected with research on student science …

Teacher Growth In Knowledge Of Conservation Of Energy And In Self-Efficacy, Paul H. Wilson

Electronic Theses and Dissertations

This study examines a conversation between a group of three in-service teachers during a professional development workshop. During the workshop, the teachers collaborated to answer a set of survey questions pertaining to energy concepts in physical science. The teachers began the survey expressing low self-efficacy in their knowledge of energy. Through this study, we were able to observe teachers as they learned new concepts. This study used a narrative analysis of their conversation. The analysis centers on changes in the teachers’ common content knowledge of conservation of energy and their expressed self-efficacy regarding that knowledge. Their knowledge was evaluated from …

Middle School Science Teachers' Vulnerability In The Written Discourse Of A Professional Learning Community, Eliza Jacobs

Electronic Theses and Dissertations

Vulnerability is omnipresent in personal and professional human experiences (Gilson, 2011; Lasky, 2005) and an unavoidable condition of work as a teacher (Bullough, 2005; Kelchtermans, 1996). It plays a role in teachers’ interaction with themselves, their students, and their professional communities, as they engage in making sense of their role in these social environments (Uitto, Kaunisto, Kelchtermans, & Estola, 2016). This study examined the written reflection journals by 12 middle school science teachers in a professional learning community (PLC) in New England. Teachers engaged with each other to co-construct knowledge and emotional understanding of their practice within this professional community. …

Agency Of In-Service Elementary Science Teachers During A Global Pandemic, Anica Miller-Rushing

Electronic Theses and Dissertations

In-service teachers of science work with unique content and pedagogical experiences. Understanding teacher agency in these circumstances will help researchers understand the actions that these teachers take, actions that are consequential for shaping teaching patterns and supporting the development of students’ scientific practices. The purpose of this study was to understand how the agency of six elementary (K–5) in-service teachers was expressed discursively during a global pandemic. The teachers’ agency was qualitatively analyzed using a case study approach (Yin, 2012, 2017) that applied discourse analysis to identify the ways in which science teacher agency is conceptualized, afforded, and constrained through …

The Impact Of Project-Based Learning On Students In High School Chemistry In Rural Maine, Brianna Degone

Electronic Theses and Dissertations

Project-based learning (PBL) is an instructional strategy that is promoted throughout education for its use of active learning and ability to connect to real-world applications. Studies have been conducted on PBL ranging from early elementary grades through graduate courses, however little research considers the effectiveness of PBL at the secondary science level. This thesis considers the use of PBL and describes the implementation of a PBL unit in a rural Maine 11th grade chemistry classroom. The thesis aims to better understand the impact PBL has on students’ content learning and additional skills acquired through the PBL learning process. Along with …

An Investigation Of Students' Use And Understanding Of Evaluation Strategies, Abolaji R. Akinyemi

Electronic Theses and Dissertations

One expected outcome of physics instruction is that students develop quantitative reasoning skills, including evaluation of problem solutions. To investigate students’ use of evaluation strategies, we developed and administered tasks prompting students to check the validity of a given expression. We collected written (N>673) and interview (N=31) data at the introductory, sophomore, and junior levels. Tasks were administered in three different physics contexts: the velocity of a block at the bottom of an incline with friction, the electric field due to three point charges of equal magnitude, and the final velocities of two masses in an elastic collision. Responses …

Investigating The Attitudes, Beliefs And Practices Of High School Chemistry Teachers Regarding The Differentiation Of Instruction, Anna Tyrina

Electronic Theses and Dissertations

Differentiation of instruction (DI) is a broad term used for a group of pedagogical tools that teachers use to individualize instruction for students of different abilities and needs. Differentiation of instruction is a practice that has been researched and characterized to have a variety of instructional benefits, some of which include increased student motivation and engagement (Tomlinson, 2001). This study sought to characterize the attitudes, beliefs, and practices of ten high school chemistry teachers in Maine regarding the differentiation of instruction. Through a phenomenological approach, interviews with these teachers were analyzed to understand how high school chemistry teachers define differentiated …

A Case Study Into Middle School Students' Conceptualizations Of Motion And Interpretations Of Negative Velocities, Peter A. Colesworthy

Electronic Theses and Dissertations

Student difficulties surrounding motion have been well documented for many years. This work was inspired by the work of former MST students into the instruction of Newton‟s Second Law of Motion at the middle school level. The purpose of this study was to further investigate how middle school students talk and reason about motion. Particular attention was paid to how students defined the term “motion,” how those definitions fit into a larger framework of what encompasses understanding motion at the middle school level, and how students justified negativity of a calculation of a negative velocity.

A tutorial lesson was developed …

Assessing The Effectiveness Of A Tool For Classifying And Assessing Student Energy Diagrams In Pre- And Post-Covid-19 Instruction, Michael Dudley

Electronic Theses and Dissertations

Energy is a broad concept that is used to interpret and understand scientific phenomena, and appears throughout the Next Generation Science Standards (NGSS) at all grade levels and across disciplines. The NGSS specifies no single approach for energy instruction, and makes use of different energy metaphors, often within individual standards. Gray, et al. (2019) created a checklist (the “Gray Checklist”) to identify whether or not a diagram exhibits evidence of core constituent ideas that align to the energy model of the NGSS. This study used the Gray Checklist to find trends in student energy diagrams that were produced during a …

How Students Communicate Knowledge: Written Versus Drawn Responses To Formative Assessment Questions In An Introductory Undergraduate Marine Science Course, Christina Siddons

Electronic Theses and Dissertations

Undergraduate science education suffers from a lack of concrete instructional strategies that address real-world postgraduate skills such as visual literacy and science communication. Research within marine science education especially lags behind other, more well-researched fields such as physics or mathematics education, both of which have extensive literature addressing specific instructional strategies that instructors can implement in the classroom. Undergraduate marine science programs overlap with content areas from chemistry, physics, and biology, and provide a rich opportunity for examining how to include more authentic educational experiences in an undergraduate classroom. However, the types of assessments that are typically employed tend to …

Investigating Maine Secondary Science Teachers Conceptualization Of Scientific Argumentation, Erin Doran

Electronic Theses and Dissertations

The Next Generation Science Standards (NGSS) aims to reform science education for grades K-12 with a central focus on students becoming doers of science as opposed to just being knowers of facts. This historical shift in standards across the United States asks for teaching science content paired with eight Science and Engineering Practices. One of the eight Science and Engineering Practices is Engaging in Argument from Evidence, which is using empirical evidence and scientific reasoning to make sense of scientific phenomena.This study examined how the practice of Engaging in Argument from Evidence is conceptualized by Maine secondary science teachers, and …

Understanding Social Factors In Small Group Work In Undergraduate Mathematics Classrooms, Jeremy R. Bernier

Electronic Theses and Dissertations

To address the ongoing labor shortage for jobs in science, technology, engineering, and mathematics (STEM) fields, many different initiatives have been undertaken by practitioners, instructors, and researchers. Two major ones have been efforts to improve undergraduate mathematics instruction and to increase diversity and inclusiveness in STEM fields, including with regards to gender identity and sexual orientation. One major ongoing shift in undergraduate mathematics instruction is a shift to increase active learning, often through tasking students to engage in collaborative problem solving in small groups. It is known that active learning strategies like these improve student outcomes over the use of …

Bridging The Gap: Including Cultural Science In Post-Secondary Education To Enhance Learning Within Sciences For Native And Non-Native Students, Tish Carr

Electronic Theses and Dissertations

Until seven years ago, there were few mechanisms in place within theWabanaki communities to keep Native students connected from middle school through college if an interest was sparked in the science, technology, engineering and math (STEM) fields. On average, less than 50 percent of Native Students graduate from high school. The past six years, the Wabanaki Youth in Science program (WaYS) has become a "bridge" for students to learn more at the secondary level about STEM fields. The next phase in the academic journey to aid student learning is to develop a model educational program that will increase Native youth …

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 …

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 …

Using Question Variations To Access Alternate Student Thinking About The Same Physical Situations, Jeffrey Mathis Hawkins

Electronic Theses and Dissertations

Assessing students’ understanding of physics is a critical element for improving physics education. This dissertation presents and demonstrates a method to better assess student understanding of physics by varying the types of questions asked of students. The method presented herein, which is based on the Specific Difficulties and Resources frameworks, involves modifying the task students are asked to complete when analyzing the physics of a particular physical situation. Creating question variations that ask students to address a particular correct or incorrect outcome of the physical situation, eliminate an incorrect outcome, or justify a correct outcome provided to them can provide …

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 …

Assessing Quantitative Reasoning In A Ninth Grade Science Class Using Interdisciplinary Data Story Assignments, Bryn W. Keenhold

Electronic Theses and Dissertations

In a data-driven world, it is necessary that students graduate from high school quantitatively literate, with the ability to interpret quantities within a context to make informed decisions for their lives. A critical component of science learning is developing the ability to make sense of data, critically evaluate it, and effectively communicate scientific ideas. 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 …

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, …

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

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

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

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

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, …
