Eliciting Elementary School Students’ Informal Inferential Reasoning Through Storytelling, Dustin Owen Smith

Dissertations

One growing area of research on statistical learning is Informal Inferential Reasoning (IIR). Makar and Rubin (2009) describe IIR as having three components: making and evaluating inferential claims, supporting claims explicitly with data, and attending to the inherent uncertainty present in statistical inference-making. This dissertation study was built around developing a method for providing opportunities for elementary school students (Grades K, 2, and 4) to engage with IIR within the context of stories and storytelling through a method called Storytelling-Questioning. After interacting with and discussing two separate stories, it was found that students of each grade level were able to …

Gravity & Einstein: Assessing The Rubber Sheet Analogy In Undergraduate Conceptual Physics, Tiffany Rae Watkins

Boise State University Theses and Dissertations

The rubber sheet analogy for Einstein’s General Relativity model of gravity is a popular way to visualize the effect mass has on the curvature of spacetime. My single group, quasi-experimental study with repeated measures was designed to assess the effectiveness of the rubber sheet analogy in teaching gravitational fields. I developed instructional materials, including a hands-on lab, to engage university students in thinking about gravity using the rubber sheet analogy. Previous research on students’ ideas about gravity informed the development of the pre/post-test. My work is an important first step in establishing a standard assessment on gravity.

A Qualitative Study Of Florida Tech Graduate Teaching Assistants’ Response To Coaching, Video Playback, And Coaching Paired With Video Playback With Regard To Their Concerns, Self-Reflections, And Practice Of Teaching, Angela Marie Fennell

Theses and Dissertations

Florida Tech’s campus-wide GTA professional development training, the GTA Seminar, has no clear theory on which it was designed, employs only measures of satisfaction and open-ended feedback, and performs limited follow-up on GTAs. Further, two pilot studies I conducted indicate that GTAs’ concerns may not be fully addressed by this seminar. This is notable because the GTA Seminar is often the only means of professional development available to more than half of the GTAs on campus. The purpose of my study was to investigate 13 GTAs’ teaching concerns, self-reflections, and practice when implementing three professional development sequences during their assignments …

Supporting Representation-Rich Problem-Solving In High School Physics, Lyrica L. Lucas

Department of Teaching, Learning, and Teacher Education: Theses and Other Student Research

The literature on physics education research (PER) promotes the use of multiple representations (such as pictures, diagrams, written explanations, and mathematical expressions) to enhance the problem-solving ability of students through instruction. The purpose of this study was to explore the use of a scaffolding strategy that involved the use of multiple representation tasks in problem-solving in a modeling physics class in high school. Another class with similar background was selected as a comparison group. In 12 in-depth problem-solving interviews of students drawn from the two classes, I investigated in detail how the students responded to the multiple representations tasks and …

Weaving Experimental Skills Throughout The Introductory Laboratory, John Zwart

Faculty Work Comprehensive List

The laboratory portion of an introductory course sequence can be used to meet a wide variety of goals ranging from illustrating phenomena studied in class, to building intuition about how the physical world works, to confronting the unexpected. Helping students develop experimental skills is a crucial goal that needs to be addressed in lab, especially in light of the fact that most introductory textbooks do not specifically address this topic. Important skills that students should learn in lab include how to analyze data, how to communicate results and the art of designing an experiment. This presentation will discuss how we …

The Magnetopause: Bringing Space Physics Into A Junior Lab, Jim Crumley, Ari Palczewski,, Stephen Kaster

MapCores Faculty Publications

Undergraduate students often have minimal exposure to many subfields
of physics which are active areas of research. Space physics
is an area that is particularly difficult to expose students to since
it builds off of another area that most undergraduates see little of,
plasma physics. The magnetopause is convenient entry point
into space physics, since it can be modeled as a pressure balance, which is
a concept familiar from introductory physics. We use the Earth's
magnetopause as the basis for a lab for junior physics majors. In
the lab students analyze results from a NASA MHD simulation and
data from …

The Discipline Of History And The “Modern Consensus In The Historiography Of Mathematics”, Michael N. Fried

Journal of Humanistic Mathematics

Teachers and students of mathematics often view history of mathematics as just mathematics as they know it, but in another form. This view is based on a misunderstanding of the nature of history of mathematics and the kind of knowledge it attempts to acquire. Unfortunately, it can also lead to a deep sense of disappointment with the history of mathematics itself, and, ultimately, a misunderstanding of the historical nature of mathematics. This kind of misunderstanding and the disappointment following from it--both raised to the level of resentment--run through the paper "A Critique of the Modern Consensus in the Historiography of …

How Do They Know It Is A Parallelogram? Analysing Geometric Discourse At Van Hiele Level 3, Sasha Wang, Margaret Kinzel

Mathematics Faculty Publications and Presentations

In this article, we introduce Sfard's discursive framework and use it to investigate prospective teachers' geometric discourse in the context of quadrilaterals. In particular, we focus on describing and analysing two participants' use of mathematical words and substantiation routines related to parallelograms and their properties at van Hiele level 3 thinking. Our findings suggest that a single van Hiele level of thinking encompasses a range of complexity of reasoning and differences in discourse and thus a deeper investigation of students' mathematical thinking within assigned van Hiele levels is warranted.

Mathematical Tasks And The Student, David Clarke, Heidi Strømskag, Heather Lynn Johnson, Angelika Bikner-Ahsbahs, Kimberly Gardner

Faculty Articles

Mathematics Education has at its core a conception of the mathematical performances that represent the aspirations of the mathematics classroom and curriculum. These performances are constituted through teacher and student participation in the activities stimulated by mathematical tasks selected by the teacher for the realization of an instructional purpose. In this nexus of activity, intention, interpretation and consequence, the mathematical task occupies a central place. This Research Forum provides an opportunity to explore and reflect upon the role that mathematical tasks play in the achievement of the goals of the international mathematics education community. Further, consistent with current curricular and …

Parts Of The Whole: Strategies For The Spread Of Quantitative Literacy: What Models Can Tell Us, Dorothy Wallace

Numeracy

Two conceptual frameworks, one from graph theory and one from dynamical systems, have been offered as explanations for complex phenomena in biology and also as possible models for the spread of ideas. The two models are based on different assumptions and thus predict quite different outcomes for the fate of either biological species or ideas. We argue that, depending on the culture in which they exist, one can identify which model is more likely to reflect the survival of two competing ideas. Based on this argument we suggest how two strategies for embedding and normalizing quantitative literacy in a given …

Quantitative Reasoning Learning Progression: The Matrix, Robert L. Mayes, Jennifer Forrester, Jennifer Schuttlefield Christus, Franziska Peterson, Rachel Walker

Numeracy

The NSF Pathways Project studied the development of environmental literacy in students from grades six through high school. Learning progressions for environmental literacy were developed to explicate the trajectory of learning. The Pathways QR research team supported this effort by studying the role of quantitative reasoning (QR) as a support or barrier to developing environmental literacy. An iterative research methodology was employed which included targeted student interviews to establish QR learning progression progress variables and elements comprising those progress variables, development of a QR learning progression framework, and closed-form QR assessments to verify the progression. In this paper the focus …

History Of Numeracy Education And Training For Print Journalists In England, Steven Harrison

Numeracy

If the history of journalism education has been a footnote to accounts of the profession’s development, then the history of numeracy training for journalists must be considered a footnote to a footnote. Despite the universally acknowledged centrality of numbers to a clear understanding of the world, many journalism students and entrants are proudly number-phobic; it is even suggested that an aversion to maths is a key reason why some choose journalism as a career. This study traces the development of numeracy education for journalists in England. It is only with the incipient professionalisation of journalism from the mid-19th century that …

Looking At The Multiple Meanings Of Numeracy, Quantitative Literacy, And Quantitative Reasoning, H. L. Vacher

Numeracy

The subject of this journal goes by a variety of names: numeracy, quantitative literacy, and quantitative reasoning. Some authors use the terms interchangeably. Others see distinctions between them. Study of psycholinguistic and ontological concepts laid out in the literature of WordNet and familiarity with the papers in this journal suggests a vocabulary matrix consisting of four rows (word senses) and three columns (word forms, namely numeracy, QL, and QR). The four word senses correspond to four sets of synonyms: {numeracy}, {numeracy, QL}, {QL, QR}, and {numeracy, QL, QR}. Each of the word forms is polysemous: “numeracy” points to the first, …

Reducing Mathematics Anxiety, Catherine Pearn

Teacher articles

Catherine Pearn discusses how to approach maths anxiety in the classroom. The symptoms of mathematics anxiety vary from expressing a dislike of mathematics to an adult who had to exit a lecture theatre in a hurry when numbers are displayed on a screen.

Scientists In The Classroom, Kent Schielke, Kathy Schmidt, Judith A. Scheppler

Publications & Research

Being an educator in the twenty-first century is exciting, stimulating, fun, challenging, and dynamic - with a great emphasis on the challenging and dynamic. The scope and depth of the materials we teach, or can teach, to our students is overwhelming and increasing exponentially every year. The list of challenges for science educators is formidable. We have found that one logical piece of the puzzle to help address these challenges is for educators to invite practicing and real-world researchers, engineers, doctors, business owners, and other STEM (science, technology, engineering, mathematics) professionals into the classroom, or take students on field trips …

Carl F. Craver And Lindley Darden: In Search Of Mechanisms: Discoveries Across The Life Sciences, Stuart Glennan

Scholarship and Professional Work - LAS

Carl Craver and Lindley Darden are two of the foremost proponents of a recent approach to the philosophy of biology that is often called the New Mechanism. In this book they seek to make available to a broader readership insights gained from more than two decades of work on the nature of mechanisms and how they are described and discovered. The book is not primarily aimed at specialists working on the New Mechanism, but rather targets scientists, students and teachers who are looking for a broad, philosophically and historically informed image of discovery in the life sciences.

The Impact Of User Centered Design On Student Motivation, Craig T. Locker

Open Access Theses

There is a current push for STEM education within the U.S.; however current studies show that students' interest to pursue STEM fields is decreasing as they progress through high school. This lose in interest has shown to have a strong tie to students' perceived levels of motivation towards the subject. The question that this studied set out to answer was if user centered design (UCD) would affect students perceived level of motivation. For this study a treatment of UCD was compared to a traditional high school engineering design curriculum, with the goal to identify if UCD would have a positive …

Student's Objectives And Achievement Strategies For Laborataory Work, Taylor M. Owings

Open Access Theses

In this study, we look at students' objectives and strategies for completing their objectives for undergraduate labs. Students across two universities and three levels of chemistry were surveyed at the beginning of the semester in the fall of 2012 using an open ended survey to identify the goals students had for the course. The students responses were coded and used to create a survey that went out to the same courses at the end of the fall semester. Using data from the fall of 2012, the survey was modified and data was collected in the fall of 2013 at one …

A Web-Based Online Collaboration Platform For Formulating Engineering Design Projects, Sainath Varikuti

Open Access Theses

Effective communication and collaboration among students, faculty and industrial sponsors play a vital role while formulating and solving engineering design projects. 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 …

Doctoral Dissertations and Projects

The search for evidence-based math interventions that are easy to use and impact academic achievement are in demand, and the impact that these interventions can have on students who struggle with math achievement is of concern. In this study, the effects of Reflex math computerized intervention to improve the automaticity of basic math facts among male and female middle school students identified as at-risk for academic failure in mathematics was examined according to differences in mean scores and based on gender. A quasi-experimental pretest-posttest nonequivalent control group design was used for the purposes of the study. Convenience sampling among students …

The Effects Of Teachers' Teaching Styles And Experience On Elementary Students' Mathematical Achievement, Angela Stanford

Doctoral Dissertations and Projects

The purpose of this causal comparative study was to determine if a statistically significant difference existed in the mathematical achievement of elementary students in classrooms led by teachers with different dominant teaching styles (Grasha, 1996) and varying years of teaching experience. Participants in this study included 29 upper elementary (grades 3-5) classroom teachers in an urban public school system located in Central Arkansas. Two one-way ANOVAs were used to compare the Arkansas Augmented Benchmark Examination's (AABE) mathematics scores of 855 students in upper elementary classrooms of teachers with varied teaching styles and years of teaching experience. A two-variable Chi-square analysis …

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 …
