Planning And Enacting Mathematical Tasks Of High Cognitive Demand In The Primary Classroom, Kelly Georgius

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

This study offers an examination of two primary-grades teachers as they learn to transfer knowledge from professional development into their classrooms. I engaged in planning sessions with each teacher to help plan tasks of high cognitive demand, including anticipating and planning for classroom discourse that would occur around the task. A detailed description of the planning and teaching that took place during the study provides information about how a teacher can learn and what a teacher learns to consider in order to plan and implement meaningful mathematical lessons. This design experiment describes the work of two teachers who participated in …

The Influence Of An Advanced Agriculture & Life Science Course On Students' Views Of The Nature Of Science, Megan N. Anderson

Open Access Theses

One of the goals in today's society is to ensure that students exiting school have the ability to understand, develop, and comprehend scientific information. For students to be able to meet these goals, it is imperative that they become scientifically literate and understand the concept of the Nature of Science (NOS). The discipline of Agricultural Education has strong connections with science and today many students are earning science credit and developing science understanding through Agricultural Education courses. If students are continuing to gain science mastery through their Agricultural Education courses, they should also be gaining adequate conceptions of science and …

Eliciting And Characterizing Students’ Mental Models Within The Context Of Engineering Design, Chelsey Ann Dankenbring

Open Access Theses

Recently, science education reform documents have called for the incorporation of engineering principles and practices into the K-12 science standards and curriculum. One way this has been done is through the use of engineering design tasks as a way for students to apply their scientific understandings to real-world problems. However, minimal studies have documented students' conceptions within the context of engineering design. Thus, the first chapter of this thesis outlines the steps taken to develop a draw-and-explain item that elicited students' mental models regarding the cause of the four seasons after finishing an engineering design task. Students' mental models regarding …

A Study Comparing Fifth Grade Student Achievement In Mathematics In Departmentalized And Non-Departmentalized Settings, Karen Nelson

Doctoral Dissertations and Projects

The purpose of this quantitative, causal-comparative study was to examine the application of the teaching and learning theory of social constructivism in order to determine if mathematics instruction provided in a departmentalized classroom setting at the fifth grade level resulted in a statistically significant difference in student achievement on the Virginia 2011 Grade 5 Mathematics Standards of Learning (SOL) Test when compared to the achievement of students in a non-departmentalized setting. Regular fifth grade education students, who attended non-Title 1, Pre-K through Grade 5 elementary schools in an urban eastern Virginia school district, participated in this study. A three-way between-groups …

The Effects Of Math Tutoring Sessions For Parents On Eighth Grade Students' Mathematics Achievement And Anxiety, Susan Scott

Doctoral Dissertations and Projects

Educators across the United States have searched for avenues to improve students' mathematics achievement since the publication of A Nation at Risk (National Commission on Excellence in Education, 1983) which reported that American students were behind students in other countries academically. Recent legislation, No Child Left Behind (2001), continues to address the need for improvement in mathematics among K-12 students. A possible intervention in middle school is to incorporate parental involvement. Numerous researchers (Colombo, 2006; Desimone, 1999; Epstein, 2008; Flynn, 2006; Henderson & Berla, 1994; Sheldon & Epstein, 2005; Wherry, 2006) have demonstrated the positive outcomes of parental involvement on …

Entry-Level Cognitive Mathematics Skill And First-Semester Mathematics Performance As Correlates Of Fall-To-Fall Retention Of Community College Students, Stephen Tyler Corbin

Educational Leadership & Workforce Development Theses & Dissertations

The purpose of this study was to investigate the relationship between first-semester mathematics performance and fall-to-fall retention for first-time-in-college, degree-seeking community college students. The study further refined the investigation by seeking to determine if the significance of this relationship was affected by student readiness for college-level mathematics as of the first semester of enrollment at the institution under study.

The sample chosen for this study consisted of 1518 first-time-in-college, degree-seeking students enrolled in fall semester 2011 at a large, multi-campus community college in Virginia. The dependent variable was fall-to-fall retention, a commonly applied student success metric in the Virginia Community …

Determining The Duration Of R&D Processes Through Monte Carlo Simulation, Florentin Smarandache, Moga Monika, Calefariu Gavrila, Sarbu Flavius Aurelian

Branch Mathematics and Statistics Faculty and Staff Publications

The research and development (R&D) processes influence the economic development of a company, because in an industry that is changing fast, firms must continually revise their projects and range of products. Therefore in order to determine the specific costs of research and development activity we have to highlight the efforts and effects of these activities and to calculate some indicators of economic efficiency. In the cost calculation process in R & D we have emphasized the identification of the components of cost and the duration of the R & D processes, as a component of the R&D cost, that is …

An Initial Look At Robotics-Based Initiatives To Engage Girls In Engineering, Jennifer Michaeli, Vukica Jovanovic, Otilia Popescu, Ana Djuric, Ece Yaprak

Engineering Technology Faculty Publications

Over the past 10 years, the use of robotic kits in K-12 Science, Technology, Engineering, and Math (STEM) initiatives as well as undergraduate engineering education has increased significantly. However, a survey of students in grades 9–12 indicated that only 2–3% of women in high school express an intention to study engineering; conversely, 16% of high school men declared that they plan to pursue an engineering degree [1]. In this paper, the authors present an initial review of published literature regarding the use of robotics in schools to identify cases where robotic kits have been used to engage girls in STEM …

Kirsten is passionate, driven, and determined, taking the initiative to bring this group of women together on campus …

Documenting Elementary Teachers' Sustainability Of Instructional Practices: A Mixed Method Case Study, Bridget Cotner

USF Tampa Graduate Theses and Dissertations

School reform programs focus on making educational changes; however, research on interventions past the funded implementation phase to determine what was sustained is rarely done (Beery, Senter, Cheadle, Greenwald, Pearson, et al., 2005). This study adds to the research on sustainability by determining what instructional practices, if any, of the Teaching SMART[reg] professional development program that was implemented from 2005-2008 in elementary schools with teachers in grades third through eighth were continued, discontinued, or adapted five years post-implementation (in 2013). Specifically, this study sought to answer the following questions: What do teachers who participated in Teaching SMART[reg] and district administrators …

Comparing Technology-Supported Teacher Education Curricular Models For Enhancing Statistical Content Knowledge, Dionne Cross Francis, Rick Hudson, Crystal Vesperman, Arnulfo Perez

Interdisciplinary Journal of Problem-Based Learning

Recent calls have been made to enhance and extend the statistical experiences of K-12 students. However, to ensure that such goals are met, teachers also need to develop deep conceptual understanding and pedagogical content knowledge that are essential to statistical thinking and reasoning. In this regard, over the past two decades, leading thinkers and professional organizations had advocated that teaching and curricula should be focused and organized around problem solving. In this paper we describe three such technology-supported curricula—a project-based learning (PjBL) unit, problem-solving activities (PS) unit, and a model-eliciting activities (MEA) unit—that align with this perspective and discuss the …

Epics: Broadening The Pathway Into Stem, Mindy Hart, Patrice M. Buzzanell, William Charles Oakes, Carla B Zoltowski

ADVANCE-Purdue Gender and STEM Research Symposium

The Engineering Projects in Community Service (EPICS) program was co-founded at Purdue University in 1995 and has since spread throughout the United States and globally with inroads into K-12 education through EPICS High. This presentation offers a synthesis of research findings and interventions gleaned from several datasets about students’ and alumni’s reported experiences with EPICS and the consequences of their participation. In particular, this presentation discusses the ways in which EPICS provides a different vantage point on the underrepresentation of women in STEM (science, technology, engineering, and math). Specifically, researchers have been tackling this issue of underrepresentation for decades with …

Angry Birds Realized: Water Balloon Launcher For Teaching Projectile Motion With Drag, Boyd F. Edwards, David D. Sam, William A. Booth, Leslie O. Jessup, Michael A. Christensen

USU Uintah Basin Faculty Publications

A simple, collapsible design for a large water balloon slingshot launcher features a fully adjustable initial velocity vector and a balanced launch platform. The design facilitates quantitative explorations of the dependence of the balloon range and time of flight on the initial speed, launch angle, and projectile mass, in an environment where quadratic air drag is important. Presented are theory and experiments that characterize this drag, and theory and experiments that characterize the non- linear elastic energy and hysteresis of the latex tubing used in the slingshot. The experiments can be carried out with inexpensive and readily available tools and …

Engaging Non-Scientists In Stem Through Problem-Based Learning And Service Learning, Andrew Tawfik, Rebecca J. Trueman, Matthew M. Lorz

Interdisciplinary Journal of Problem-Based Learning

This study follows the evolution of a single biology course designed for non-science majors. In its original design, the course used only traditional pedagogical techniques, such as lecture and textbook homework assignments. Over several iterations of the course, the class combined problem-based learning (PBL) and service learning to better support student knowledge. For this study, our goal was for students to learn biology concepts as they engaged in a lake cleanup project within the greater Chicago metropolitan area. Data sources consisted of pretest, posttest, and final exam scores to assess learning. The results suggest the combination of PBL and service …

An Investigation Of How Preservice Teachers Design Mathematical Tasks, Elizabeth Karen Zwahlen

Theses and Dissertations

The tasks with which students engage in their mathematics courses determine, for a large part, what students learn. Therefore, it is essential that teachers are able to design tasks that are worthwhile for developing mathematical understanding. Since practicing teachers seldom incorporate worthwhile mathematical tasks in their lessons, we would expect that they did not become proficient at designing worthwhile tasks while in their teacher education programs. This thesis describes a study that investigated what preservice secondary teachers attend to as they attempt to design worthwhile mathematical tasks. Three participants were selected from a course at a large private university where …
