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 …

Assessing College Students' Understanding Of Geologic Timescales, Ethan Couture

Honors College

Geologic timescales are central to many concepts in the natural sciences, including evolution, climate change and plate tectonics. However, geologic time scales can be challenging to appreciate, especially for those who have not had exposure to such topics previously. During primary and secondary education (K-12) students are provided with foundational information about geology that is then further developed in specialized classes in college. Yet most students are not getting this foundation, which could arguably lead to deficits in their post-secondary education. Despite the importance of these concepts, especially for those interested in careers associated with geologic timescales, there have been …

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 …

Socioscientific Issues-Based Instruction: The Messier Side Of (Leading) Science Teaching, Savannah Graham, Mark Bloom, Sarah Quebec Fuentes, Jo Beth Jimerson

Journal of Educational Supervision

The present case centers on a socioscientific issues-based lesson taught by a preservice teacher (PST) in an AP Biology class. The PST designed and delivered a lesson on disease transmission and ways to avoid infection with connections to the COVID-19 pandemic mask mandates and vaccine reticence. The Principal received several emails from parents (positive and negative), citing the incorporation of political issues and critical race theory into the science lesson. With this framing, the case depicts how the Principal, PST, university supervisor, and cooperating teacher navigate the situation. The case highlights the role of school leader as instructional leader. In …

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 …

Addressing Dehumanizing Mathematical Practices: Using Supervisory Leaders’ Experiential Knowledge To Transform The Mathematics Classroom, Allison Mudd, Stefanie D. Livers, Artavia Acklin, Tommy Acklin, Linda D. Harper, Tiffany Davis

Journal of Educational Supervision

Deficit language concerning historically marginalized students pervades much of education today. Black, Brown, and Indigenous children experience marginalization and dehumanizing practices in classrooms instead of participating in a safe space to learn and grow. For this paper we employ a crucial component from Critical Race Theory to address systemic racism in schools: we listen to the lived experiences of professionals of color. These personal narratives open avenues for social justice through critiquing current and historical political, economic, and sociocultural practices and policies. This study examined how four Black collaborators – one high school principal, one middle school principal, one elementary …

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 …

An Evolutionary Approach To Crowdsourcing Mathematics Education, Spencer Ward

Honors College

By combining ideas from evolutionary biology, epistemology, and philosophy of mind, this thesis attempts to derive a new kind of crowdsourcing that could better leverage people’s collective creativity. Following a theory of knowledge presented by David Deutsch, it is argued that knowledge develops through evolutionary competition that organically emerges from a creative dialogue of trial and error. It is also argued that this model of knowledge satisfies the properties of Douglas Hofstadter’s strange loops, implying that self-reflection is a core feature of knowledge evolution. This mix of theories then is used to analyze several existing strategies of crowdsourcing and knowledge …

Applying Cluster Analysis To Student Responses From Energy Surveys For Identification Of Commonalities In Their Understanding, Arianna Giguere

Honors College

Energy is a complicated model that has been developed to describe matter to matter interactions. Since energy can be challenging to define, there are inconsistencies among even teachers and physicists in how they define the concept. It is no wonder that students themselves carry misconceptions and confusions. While it may be difficult to teach, an understanding of energy from a young age is essential for the future of technology, climate change, and scientific discoveries. Middle school students in Maine are required to learn about energy transformation, conservation, and forms, and from 2011-2018, researchers at the University of Maine administered multiple …

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 …

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 …

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 …

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 …

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, …
