With the advent in the web technology, online platforms and systems have been proposed to facilitate interactions and collaboration among different stakeholders in the context of senior design projects. However, there are noticeable gaps in the literature with respect to understanding the effects of online collaboration platforms for formulating engineering design projects. Most of the existing literature is focused on exploring the utility of online platforms on activities after the problem is defined and teams are formed. Also, there …

Effective Geoscience Pedagogy At The Undergraduate Level, Kelsey Warden

Open Access Theses

This investigation used constructivist pedagogical methods within the framework of an introductory level undergraduate geoscience course to gauge both the changes in attitude and cognition of students. Pedagogy was modified in the laboratory setting, but maintained in the lecture setting and homework. Curriculum was also maintained in the lecture, but was changed in the laboratory to emphasize the large concepts and systems stressed in Earth Science Literacy Principles. Student understanding of these concepts and systems was strengthened by factual knowledge, but recall and memorization were not the goal of the laboratory instruction. The overall goal of the study was to …

The Effect Of Inquiry-Based, Hands-On Labs On Achievement In Middle School Science, Donna Miller

Doctoral Dissertations and Projects

The purpose of this quasi-experimental study was to measure the difference in science achievement between students who had been taught with an inquiry-based, hands-on pedagogical approach and those who had not. Improving student academic achievement and standardized test scores is the major objective of teachers, parents, school administrators, government entities, and students themselves. One major barrier to this academic success in Georgia, and the entire United States, has been the paucity of success in middle level science classes. Many studies have been conducted to determine the learning approaches that will best enable students to not only acquire a deeper understanding …

The Effects Of A Direct-Instruction Math Intervention On Standardized Test Scores Of At-Risk Middle School Students, Charles Moore

Doctoral Dissertations and Projects

Educators are seeking ways to improve student academic achievement in math and to increase math standardized test scores because of the requirements of the reauthorization of the Elementary and Secondary Education Act, known as the No Child Left Behind Act (NCLB), Individuals with Disabilities Education Act (IDEA), and Race to the Top initiative (RTTT). One such intervention in middle school is a direct-instruction math program. This causal-comparative study examined the relationship between a direct-instruction math intervention and math achievement on standardized test scores of at-risk middle school students. This study compared the differences in the mean scale scores for at-risk …

Using Schematic-Based And Cognitive Strategy Instruction To Improve Math Word Problem Solving For Students With Math Difficulties, Lisa L. Morin

Communication Disorders & Special Education Theses & Dissertations

For students with math difficulties (MD), math word problem solving is especially challenging. The purpose of this study was to examine a math word problem solving strategy, bar model drawing, to support students with MD. The study extended previous research that suggested that schematic-based instruction (SBI) training delivered within an explicit instruction framework can be effective in teaching various math skills related to word problem solving. As a more generic schema approach, bar model drawing may serve as an effective form of SBI that can be developed across word problems. Moreover, the bar model approach has the potential to enhance …

Professional Identity And Pedagogical Discontentment In High School Science Teachers Participating In A Professional Development Institute, Stephanie J. Hathcock

Teaching & Learning Theses & Dissertations

Although science teachers regularly participate in PD experiences involving reform-based practices, even our best teachers struggle to change their teaching practices to coincide with these pedagogics, and when they do change, it occurs at differential rates. The aim of this study was to better understand teachers' self-systems by analyzing their experiences in a PD institute program through the lens of professional identity. This multiple case study involved five high school science teachers participating in a summer PD initiative. Data were collected through interviews, written reflections and exploration and commitment cards, and a scale designed to capture participants' perceived level of …

Beliefs Of Efficacy And Elementary Teachers’ Computational Skills, Vanessa Hinton, Margaret Flores, Kate Simmons

Georgia Educational Researcher

Early mathematics content that is taught in elementary school lays the foundation for students’ advanced mathematics performance. Thus, researchers show it is important that pre-service elementary teachers build a strong background in numbers and operations, as well as efficacy beliefs in mathematics instruction. This study expands the literature in the investigation of pre-service teachers’ efficacy beliefs and mathematical knowledge by making comparisons of pre-service elementary teachers’ views of efficacy to their overall ability in computation skills. Results show that elementary pre-service teachers who demonstrated lower scores in efficacy beliefs also had significantly lower computation scores. Implications for teacher preparation are …

Geometry: A Medium To Facilitate Geometric Reasoning Among Sixth Grade African-American Males, Olufunke Adefope

Georgia Educational Researcher

In this article, the author describes how a curricular unit that provided opportunities for active engagement and participation was used to support the geometric reasoning of sixth grade African American (AA) male students. The curricular unit was designed to support students’ understanding of quadrilaterals. Data sources (pre- and post-tests, video recordings of classroom episodes, mathematics interviews) were analyzed through quantitative and qualitative methods. Findings showed that students improved in their understanding of quadrilateral classifications. Specifically, students were able to use their knowledge of geometry to evaluate the relationships between pairs of quadrilaterals. However, levels of understanding were varied. Little research …

Mathematical Telling In The Context Of Teacher Interventions With Collaborative Groups, Brandon Kyle Singleton

Theses and Dissertations

Teacher telling is underrepresented in the mathematics education reform literature and deserves additional scrutiny. This case study examined a skilled teacher's telling practices during a university mathematics content course for pre-service elementary teachers. I identified telling practices through discourse analysis, attending to the presence of mathematics and the contribution of new structure or ideas from the teacher. The teacher utilized seven unique types of mathematical telling while supporting collaborative group work on tasks. The study identified subtle telling, implicit telling, and explicit telling. The results suggest that mathematical telling is an integral part of the teacher's role in inquiry-based instruction …

Faculty Publications

Mathematics classroom coaching is used across the United States as a means for improving instruction, with the ultimate goal of improving student learning. The job assignments of coaches can vary widely across schools and districts. Regardless of the various forms that coaching can take, there is the consistent expectation that a coach's day-to-day work will positively influence classroom instruction. The study reported here attempts to gain a more complete picture of the job of an elementary mathematics coach based on the observation of seven coaches in five different districts for a day. We report the variety of ways we observed …

Investigating Children's Intuitive And Analytical Thinking About Path Length As A Developmental Phenomenon, Cheryl Lynn Eames

Theses and Dissertations

Children's conceptions of length measurement has been the focus of research that has built on the work of Piaget and his colleagues to produce developmental accounts for the acquisition of conceptual and procedural knowledge. Prior research focused on children's developing conceptions of length measurement for straight or rectilinear paths; however, little is known about how these conceptions grow beyond the elementary grades. The present study increased the scope of this research beyond elementary grades to include middle and secondary level students, exploring the development of students' intuitive and analytical thinking for determining the length of a curved path across a …

Creating A Stem Identity: Investment With Return, Janet Callahan, Patricia Pyke, Susan Shadle, R. Eric Landrum

Materials Science and Engineering Faculty Publications and Presentations

Establishing a strong STEM (science, technology, engineering and mathematics) identity at Boise State University, a metropolitan campus with approximately 3,655 undergraduate STEM students and a total undergraduate enrollment of approximately 19,042 (16,136 FTE) has been an important step toward creating a climate conducive to facilitating fundamental change. Examples of such change include building collaborations among faculty within and across departments, establishing the identity of students as part of a community beyond their chosen major, improving the efficiency and effectiveness of university systems, and perhaps most importantly, developing a framework to think deliberately about ways to effect change. This paper is …

Investigating The Proposed Affordances And Limitations Of The Substance Metaphor For Energy, Lisa Goodhew

Honors Projects

This study explores the instructional advantages and disadvantages of representing energy as a material substance; this is done in the context of a computer simulation that illustrates processes of energy transfer and transformation. These affordances and limitations have been proposed in science education literature as extensions of the substance metaphor itself, but there is little empirical evidence to support them. This study is intended to provide preliminary empirical evidence for these affordances and limitations. We examine data from eight interviews conducted with students from Seattle Pacific University’s introductory physics classes as they used the simulation. We explore the hypotheses that …

Connecting Teaching Practice To Student Efficacy In Undergraduate Mathematics, Sandra Becker

Master's Theses and Doctoral Dissertations

Academic efficacy plays a critical role in student success in math learning at all levels due to its impact on persistence, motivation, and academic performance. This research aimed to connect student efficacy with key aspects of the instructional environment in six undergraduate math classes. Student surveys indicated significant differences in mean efficacy between classes, as well as significant differences in student perceptions of teacher behavior between the efficacy groups. Findings from observations of the classes revealed that key aspects of the instructional discourse varied by efficacy group. Instructors in higher efficacy classes tended to have more personal connections with students …

Promoting Wellness Through Mindfulness-Based Activities, Malgorzata Powietrzynska

Dissertations, Theses, and Capstone Projects

The central idea of this dissertation is mindfulness framed as a sociocultural, secular, and multidimensional construct involving attention that is purposeful, in the present moment, and non-judgmental. Mindfulness represents a unification of century-old contemplative Eastern traditions (including Buddhism) and the recent developments of modern, Western science. Hence, supported by the emerging scientific evidence, I argue that mindfulness practices have a potential to offer a wide range of benefits related to wellness. In particular, I report on our hermeneutic-phenomenological studies investigating the centrality of emotions in teaching and learning. Our findings confirm that when adopted in education, mindfulness may mediate positive …

The Impact Of School-Level Factors On Minority Students' Performance In Ap Calculus, Phillip Bruce Pearson

Dissertations and Theses

In recent years, Science, Technology, Engineering, and Technology (STEM) talent pool has re-emerged as a national priority. Certain racial and ethnic groups are dramatically underrepresented in STEM careers and STEM educational programs, an especially serious concern given demographic transitions underway in the United States. The College Board's Advanced Placement (AP) Calculus program provides one way in which students can gain exposure to college-level mathematics while still in high school. This study analyzed factors that contribute to the success of minority students in AP Calculus using a large, longitudinal (2007-2012), geographically distributed dataset which included important school-level variables and AP scores …

Being Mathematical Relations: Dynamic Gestures Support Mathematical Reasoning, Caro C. Williams-Pierce

Mathematics and Statistics Faculty Scholarship

In mathematics classrooms, body-based actions, including gestures, offer an important way for students to become mathematical ideas as they engage in mathematical practices. In particular, a type of gesture that we call a dynamic depictive gesture allows learners to model and represent fluid transformations of mathematical objects with their bodies. In this paper, we report on two empirical studies – one in which dynamic gestures were observed, and one where these gestures were directed. We conclude that dynamic gestures are a key element in successful justification and proof activities in mathematics.

The University Of Nebraska State Museum, Robert F. Diffendal Jr.

Robert F. Diffendal, Jr., Publications

I first walked through the doors of Morrill Hall on the main or City Campus of the University of Nebraska on a day late in August of 1962 and thought that I had entered paleontology heaven. Morrill Hall then housed the University of Nebraska State Museum (UNSM). most of the Geology Department, and some other parts of university units. I was a new graduate student hoping to pursue research in invertebrate paleontology in the Department of Geology and was on my way to see the department chairman for the first time. When I entered the building I walked through a …

A Narrative Study Of Novice Elementary Teachers' Perceptions Of Science Instruction, Roberta Harrell

Electronic Theses and Dissertations

It is hoped that, once implemented, the Next Generation Science Standards (NGSS) will engage students more deeply in science learning and build science knowledge sequentially beginning in Kindergarten (NRC, 2013). Early instruction is encouraged but must be delivered by qualified elementary teachers who have both the science content knowledge and the necessary instructional skills to teach science effectively to young children (Ejiwale, 2012, Spencer, Vogel, 2009, Walker, 2011). The purpose of this research study is to gain insight into novice elementary teachers’ perceptions of science instruction.

This research suggests that infusion of constructivist teaching in the elementary classroom is beneficial …

Hear What They Say And Watch What They Do: Predicting Valid Mathematical Proofs Using Speech And Gesture, Caro C. Williams-Pierce

Mathematics and Statistics Faculty Scholarship

In mathematics, practices of proof are notoriously difficult for learners to adopt. In prior work, we found that when providing verbal justifications, learners’ speech patterns predict whether their justifications are mathematically sound. However, current views on the embodied nature of cognition suggest that actions and speech may co-constitute reasoning processes. The current study investigated whether the gestures learners use while formulating proofs also predict proof validity. 120 undergraduates provided verbal justifications for two mathematical tasks. We analyzed speech patterns in participants’ justifications using text analysis software, and we coded participants’ gestures as dynamic or static. Results showed that dynamic gestures …

Children, Mathematics, And Videotape: Using Multimodal Analysis To Bring Bodies Into Early Childhood Assessment Interviews, Amy Noelle Parks, Mardi Schmeichel

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Despite the increased use of video for data collection, most research using assessment interviews in early childhood education relies solely upon the analysis of linguistic data, ignoring children’s bodies. This trend is particularly troubling in studies of marginalized children because transcripts limited to language can make it difficult to analyze embodied power relations between majority researchers and minority children. This article responds to this problem by outlining a theoretical position on power and bodies, describing multimodal analysis strategies, and using these strategies to analyze the subject positions available during a mathematical assessment interview for three African American preschool child-participants and …

Chemistry Graduate Teaching Assistants: A Comparison Of The Classroom Discourse Within Expository And Problem-Based Learning Laboratories, Kelley M. Current

Masters Theses

Graduate Teaching Assistants (GTAs) commonly function as instructors within undergraduate chemistry laboratories. This study sought to explore and describe GTA classroom discourse within two distinct instructional modes, using discourse analysis as the theoretical framework. Theclassroom discourse within a series of verification style labs was comparedto the classroom discourse produced within a set of Problem-Based Learning (PBL) labs. The results suggest three primary findings: (1) the apparent relationship between the instructional mode and form of GTA classroom discourse, (2) the patterns in classroom discourse observed within a given instructional mode repeat, irrespective of content, and (3) the classroom discourse observed within …

Teaching & Learning Faculty Publications

In recent years there has been a renewed interest on science, technology, engineering, and mathematics (STEM) education. Following this interest, science centers' staff started providing technology enhanced informal STEM education experiences. The use of well-designed mobile and ubiquitous forms of technology to enrich informal STEM education activities is an essential success factor. The goal of our research is to investigate how technology applications can be better used and developed for taking full advantage of the opportunities and challenges they provide for students learning about STEM concepts. In our approach, we have conducted a series of interviews with experts from science …

A Method For Assessing And Describing The Informal Inferential Reasoning Of Middle School Students, Joshua Michael Goss

Dissertations

Informal Inferential Reasoning (IIR) has emerged in the last decade in the study of statistics education. Developing students’ IIR ability is seen as a way of preparing students for the important topic of Formal Statistical Inference (FSI); however, research is still needed in order to investigate how students transition between informal and formal statistical reasoning. A primary difficulty is that we do not have a way of assessing and describing students’ IIR ability levels. In order to address this, an Assessment of Informal Inferential Reasoning (AIIR) was developed, along with a Structure of Observed Learning Outcomes (SOLO) taxonomy (Biggs & …

Integrating Nanotechnology Into The Undergraduate Chemistry Curriculum: The Impact On Students’ Affective Domain, Jacinta M. Mutambuki

Dissertations

High attrition rates in science, technology, engineering, and mathematics (STEM) continue to be documented in the undergraduate education in the United States (U.S.). There is a growing concern that the U.S. will fall short of 3 million graduates by 2018. Furthermore, the literature indicates that about 36% of 4-year college graduates lack adequate critical thinking skills, complex reasoning, and communication skills relevant to the current job market. Reasons for these observations relate to the overemphasis on content knowledge; lack of content relevance; lack of interest in STEM courses; and dominance of expository teaching methods in classrooms. Given its relevance in …
