Analyzing The Online Environment: How Are More Effective Teachers Spending Their Time?, Scott Davis Barrentine Aug 2017

Analyzing The Online Environment: How Are More Effective Teachers Spending Their Time?, Scott Davis Barrentine

Dissertations and Theses

Teaching at an online school is so different from classroom teaching that traditional training includes few of the skills necessary to be a successful online teacher. New teachers to an online environment face a steep learning curve in how they'll use the instructional technology, prioritize their time, and establish relationships with their students. The literature has advice for these teachers about effective online practices, but there has been little research to establish which strategies are most effective in motivating students. This pre-experimental study, conducted at an online 6th-12th grade hybrid school, investigated the practices used more often by the ...


Employing Multivariate Logistic Regression Analysis To Better Understand The Relationship Between Individuals’ Anthropogenic Climate Change Acceptance And Belief In Anti-Climate Change Dissenter Messages, Andrew Phillip Keller Bentley Aug 2017

Employing Multivariate Logistic Regression Analysis To Better Understand The Relationship Between Individuals’ Anthropogenic Climate Change Acceptance And Belief In Anti-Climate Change Dissenter Messages, Andrew Phillip Keller Bentley

Dissertations

Organized climate change dissention groups spend a considerable amount of time and energy developing messages designed to convince the public that anthropogenic climate change is neither a reality nor a threat. These messages work against the efforts of climate educators and can be divided into two categories; messages that provide alternative explanations for warming, or messages that attack the work of scientists studying anthropogenic climate change. There has been a lack of research regarding any correlation between individuals’ agreement with these messages and their rejection of anthropogenic climate change. Establishing a correlation would be an indication that educators should take ...


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 ...

This study addressed how different instructional strategies affected preservice elementary teachers’ levels of math anxiety and their achievement in a math content course while considering descriptions of their experiences in the course in relation to their math anxiety and achievement. The instructional strategies used were traditional teaching methods and inquiry-based learning (IBL). A mixed methods embedded design was used in which the major design of the study is a nonequivalent control group design, where the collection of data occurred before, during, and after the intervention. There were 103 participants who were elementary education preservice teachers with 58 of them being ...


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 ...


Effects Of Historical Story Telling On Student Understanding Of Nos And Mendelian Genetics, Cody Tyler Williams Aug 2017

Effects Of Historical Story Telling On Student Understanding Of Nos And Mendelian Genetics, Cody Tyler Williams

Dissertations

Science education researchers have long advocated the central role of the nature of science (NOS) for our understanding of scientific literacy. NOS is often interpreted narrowly to refer to a host of epistemological claims associated with the process of science and the limitations of scientific knowledge. Despite its importance, practitioners and researchers alike acknowledge that students have difficulty learning NOS and that this in part reflects how difficult it is to teach. Many teachers are uncomfortable with taking time away from traditional science content instruction. One promising method for teaching NOS and science content involves an explicit and reflective approach ...


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 ...

Using Mobile Technology To Increase The Math Achievement And Engagement Of Students With Disabilities, Dominique Marie Tetzlaff

UNLV Theses, Dissertations, Professional Papers, and Capstones

The advent of advanced technologies provides new opportunities for delivering instruction to students with disabilities. Many classrooms have access to mobile devices, such as iPads and Kindles, and educators utilize these devices to differentiate instruction and augment teacher-led instruction. This delivery method, known as blended learning, can create an enriched learning environment where students are exposed to individualized lessons that are self-paced and provide multiple modes of presentation. However, there is little empirical investigation into how students interact with digital devices or what components of online learning directly impact student learning and engagement with the content. In order to design ...

Teachers’ Perceptions Of Educational Games That Keep Score Of Cooperative Performances, Theodore Alden Wohlfarth Jul 2017

Teachers’ Perceptions Of Educational Games That Keep Score Of Cooperative Performances, Theodore Alden Wohlfarth

Dissertations

The scoring systems used in traditional sports and games are founded on the zero-sum premise that players are on opposite sides and one side can win only if the other side loses. These scoring systems may be effective at nurturing zero-sum mindsets and providing data for assessing performance in win-lose relationships. If so, games that use different scoring systems can be used to facilitate the development of collaborative mindsets, nurture win-win skills between diverse groups, and enable objective self-assessment of performances in non-zero-sum events when engaging with those on “other sides.” Although economic game theory has rich reservoirs of research ...


Stereotype Threat And Effects Of Students' Perception Of Their Math Teacher's Fairness On Their Math Self-Efficacy, Alexis Jocelyn Devigal Jul 2017

Stereotype Threat And Effects Of Students' Perception Of Their Math Teacher's Fairness On Their Math Self-Efficacy, Alexis Jocelyn Devigal

Dissertations and Theses

Gender inequalities perpetuated by educational and occupational segregation may be exacerbated in part by socialization processes that occur in the years leading up to when high school students typically begin considering postsecondary options. Students’ feelings of self-efficacy in certain subjects can be an important factor that informs their decisions to pursue coursework and programs. This study used stereotype theory to understand how students' perceptions of their 9th grade math teacher's fairness affected their 11th grade math efficacy and how this relationship was moderated by the gender of the student and their math teacher. Using the High School Longitudinal Study ...


Cross Case Study Of An Elementary Engineering Task, John Heffernan Jul 2017

Cross Case Study Of An Elementary Engineering Task, John Heffernan

Doctoral Dissertations

Designerly play has been identified as a fundamental component of childhood learning (Baynes, 1994; Petroski, 2003). However, as students enter grade one and beyond, the increasing academic focus has resulted in the loss of opportunities for designerly play (Zhao, 2012). At the same time, there are increasing calls to increase the number, skill, and diversity of STEM workers (Brophy, Portsmore, Klein, & Rogers, 2008). The robotics based Elementary Engineering Curriculum (Heffernan, 2013) - used by students in this study - and other similar projects have the potential to increase the STEM pipeline but elementary engineering is not well-understood. Research is needed to understand how to teach engineering to students as their cognitive, motor, and social skills rapidly develop in elementary school (Alimisis, 2012; Crismond & Adams, 2012; Mead, Thomas, & Weinberg, 2012; Penner, Giles, Lehrer, & Schauble, 1997; Roth, 1996; Schunn, 2009; Wagner, 1999). The literature review and theoretical frameworks chapters of this study determined the most relevant theoretical frameworks, engineering design process models, and existing research that is relevant to ...

How Teachers’ Beliefs About Climate Change Influence Their Instruction, Student Understanding, And Willingness To Take Action., Molly Trendell Nation Jul 2017

How Teachers’ Beliefs About Climate Change Influence Their Instruction, Student Understanding, And Willingness To Take Action., Molly Trendell Nation

Graduate Theses and Dissertations

Climate change science is complex and controversial in nature, yet seen by educators and policy makers as an important topic to be taught within secondary science education. This is becoming increasingly evident with the inclusion of climate change into the Next Generation Science Standards (NGSS) for Earth and Space Sciences as well as Life Science courses (NGSS, 2013). An overwhelming amount of information is available to students; however, it is often misrepresented, politically inflated and falsified, and littered with misconceptions (Dawson & Carson, 2014; Gayford, 2002). It is critical to engage students in discourse that challenges them ethically in order for students to ...

Prevalence Of Typical Images In High School Geometry Textbooks, Megan N. Cannon Jun 2017

Prevalence Of Typical Images In High School Geometry Textbooks, Megan N. Cannon

Graduate Theses and Dissertations

Visualization in mathematics can be discussed in many ways; it is a broad term that references physical visualization objects as well as the process in which we picture images and manipulate them in our minds. Research suggests that visualization can be a powerful tool in mathematics for intuitive understanding, providing and/or supporting proof and reasoning, and assisting in comprehension. The literature also reveals some difficulties related to the use of visualization, particularly how illustrations can mislead students if they are not comfortable seeing concepts represented in varied ways. However, despite the extensive research on the benefits and challenges of ...


An Examination Of The Relationship Between Professional Development Providers' Epistemological And Nature Of Science Beliefs And Their Professional Development Programs, Alfonso Garcia Arriola Jun 2017

An Examination Of The Relationship Between Professional Development Providers' Epistemological And Nature Of Science Beliefs And Their Professional Development Programs, Alfonso Garcia Arriola

Dissertations and Theses

In the last twenty years in US science education, professional development has emphasized the need to change science instruction from a direct instruction model to a more participatory and constructivist learning model. The result of these reform efforts has seen an increase in science education professional development that is focused on providing teaching strategies that promote inquiry learning to learn science content. Given these reform efforts and teacher responses to professional development, research seems to indicate that whether teachers actually change their practice may depend on the teachers' basic epistemological beliefs about the nature of science. The person who builds ...


The Effects Of Interactive Word Walls On Students With Learning Disabilities In The Secondary Science Classroom, Casey Elizabeth Eustace-Debaun Jun 2017

The Effects Of Interactive Word Walls On Students With Learning Disabilities In The Secondary Science Classroom, Casey Elizabeth Eustace-Debaun

Theses and Dissertations

Effective approaches for teaching vocabulary to various populations of learners is a topic of current research (Barr, Eslami, & Malatesha, 2012) yet little research is dedicated to students with learning disabilities in the science classroom. Within this study the interactive word wall was used as a tool to build vocabulary and to encourage usage of new subject-specific terminology. The experiment utilized quasi-experimental pre-post test comparison group design using interrupted time-series (Johnson & Christiensen, 2007) due to the inability to randomize participants and establish a clear control group. The data was collected across four units of terminology and with a student satisfaction survey ...

Based on the meta-analysis of each of these methods, a hybrid method has been constructed to adapt in the American Common Core algebra classroom.


Perspectives On Emotional Climate Associated With Classroom Interactions, Hiro Komatsubara Jun 2017

Perspectives On Emotional Climate Associated With Classroom Interactions, Hiro Komatsubara

Dissertations, Theses, and Capstone Projects

It is difficult for students to learn and teachers to teach in today’s classroom environment especially when events involving strong emotional contradictions occur in classrooms. Such events may elicit emotions that negative affect, teaching, learning and wellness. Various studies show that high levels of negative emotions create stressful classroom environments, and that a positive Emotional Energy (EE) in the classroom encourages attentiveness, enthusiasm and interest. Therefore, it is highly likely that creating calm learning environments by ameliorating classroom participants’ emotional intensity and increasing their mindfulness and awareness will produce positive outcomes. Using both quantitative and qualitative measures this study ...

The Impact Of Teacher Perception Of Professional Learning Communities On Student Algebraic Achievement, Tyrone John

Dissertations, Theses, and Capstone Projects

In this study, I investigate the impact of teachers’ perceptions of professional learning communities on student algebraic achievement. Furthermore, I also investigate whether these relationships manifest differently for males compared to females. Research indicates that teacher quality and professionalism are considered the most critical factors affecting academic achievement. In this dissertation, I interrogate this issue by employing multivariate analyses using data retrieved from the High School Longitudinal Study of 2009 (HSLS:09) and 2012 follow-up. HSLS:09 used a nationally representative sample of over 21,000 ninth-grade students, which incorporated teacher, parent, school administrator, and school counselor input to create ...

Experiencing The Implementation Of New Inquiry Science Curricula, Peter S. Ower

College of Education Theses and Dissertations

Using a phenomenological methodology, a cohort of four experienced science teachers was interviewed about their experience transitioning from traditional, teacher and fact-centered science curricula to inquiry-based curricula. Each teacher participated in two interviews that focused on their teaching backgrounds, their experience teaching the prior traditional curriculum, and their experience teaching the new inquiry-based curriculum. The findings are presented as a narrative of each teachers’ experience with the new curriculum implementation. Analyzing the data revealed four key themes. 1) The teachers felt trapped by the old curriculum as it did not align with their positive views of teaching science through inquiry ...


Using Concept Maps To Monitor Knowledge Structure Changes In A Science Classroom, Leah J. Cook Jun 2017

Using Concept Maps To Monitor Knowledge Structure Changes In A Science Classroom, Leah J. Cook

Dissertations

The aim of this research is to determine what differences may exist in students’ structural knowledge while using a variety of concept mapping assessments. A concept map can be used as an assessment which connects concepts in a knowledge domain. A single assessment may not be powerful enough to establish how students’ new knowledge relates to prior knowledge. More research is needed to establish how various aspects of the concept mapping task influence the output of map creation by students. Using multiple concept maps and pre-instruction and postinstruction VNOS instruments during a 16-week semester, this study was designed to investigate ...

Academic Emotion And Self-Efficacy Impacting Sense Of Math Class Belonging In College Students, Kaitlyn Yavorsky May 2017

Academic Emotion And Self-Efficacy Impacting Sense Of Math Class Belonging In College Students, Kaitlyn Yavorsky

Theses and Dissertations

A student's sense of belonging has been shown to have positive effects on a student, such as increased motivation and performance (Neel & Fuligni, 2013; Mcmahon, Parnes, Keys, & Viola, 2008). Positive emotions within the academic setting as well as strong self-efficacy have also been found to have these implications (Pekrun, 2006). The impact of emotions in an academic setting and self-efficacy on student's sense of belonging in the classroom is a relatively novel research topic especially in college students. If found, the correlation between academic emotions and self-efficacy along with their impact on sense of belonging can be used to support ...
