A Mathematician's Overview Of The Virginia Elementary Mathematics Specialist Program, L. D. Pitt

Journal of Mathematics and Science: Collaborative Explorations

This article discusses the mathematics component of the Mathematics Specialist master's degree program in the "Virginia Mathematics Specialist Project" (VMSP). It includes my personal views on the significant mathematical knowledge and skills that Mathematics Specialists need, the mathematics that is taught in the Mathematics Specialist courses, and my thoughts on what appear to be the substantial mathematical abilities and aptitudes that are required by successful Mathematics Specialists in their work. The interpretations I present are highly personal and are undoubtedly dependent on my personal history, a short description of which is given (see Appendix A).

Meaningful Distributed Instruction— Conceptual Previews For Symbolic Procedures, Edward C. Rathmell

Faculty Work

Understanding a symbolic procedure means far more than “getting the right answer.” A mathematical symbolic procedure or written skill involves step-bystep thinking that leads from a computational problem to a solution. Memorizing this step-by-step procedure may enable a student to answer the problem, even answer it correctly. Yes, that is important, but understanding means much more.

An Analysis Of Science Content And Representations In Introductory College Physics Textbooks And Multimodal Learning Resources, Suzanne Mary Donnelly

Legacy Theses & Dissertations (2009 - 2024)

This study features a comparative descriptive analysis of the physics content and representations surrounding the first law of thermodynamics as presented in four widely used introductory college physics textbooks representing each of four physics textbook categories (calculus-based, algebra/trigonometry-based, conceptual, and technical/applied). Introducing and employing a newly developed theoretical framework, multimodal generative learning theory (MGLT), an analysis of the multimodal characteristics of textbook and multimedia representations of physics principles was conducted. The modal affordances of textbook representations were identified, characterized, and compared across the four physics textbook categories in the context of their support of problem-solving.

Understanding College Students' Disconnections With Mathematics, Karen Jean Edwards

Legacy Theses & Dissertations (2009 - 2024)

This study explores the disconnections introductory college mathematics students experience with mathematics.

How Our Health Depends On Biodiversity, Eric Chivian M.D., Aaron Bernstein M.D., M.P.H.

Ecosystem Disruption & Climate Change

The eminent Harvard biology Professor Edward O.Wilson once said about ants, “We need them to survive, but they don’t need us at all.” The same, in fact, could be said about countless other insects, bacteria, fungi, plankton, plants, and other organisms. This fundamental truth, however, is largely lost to many of us. Rather, we humans often act as if we are totally independent of Nature, as if our driving thousands of other species to extinction and disrupting the life-giving services they provide will have no effect on us whatsoever.

The Implementation Of Interactive Science Notebooks And The Effect It Has On Students Writing, Eva Braxton

Electronic Theses and Dissertations

The purpose of this study was to determine whether or not my practice of implementing Interactive Science Notebooks (ISN) impacts 4th grade students writing in science. Through this action research, students' writing was analyzed to determine whether the use of ISN affected students' use of details, support claims and justifications in their written responses. Also through the use of the Interactive Science Notebook, students' use of science vocabulary in their writing was also analyzed. Finally, students' reflective writing practices were examined in order to determine how students understood and explored physical science. A triangulation of data gathered consisted of the …

Developing Fourth Graders' Proficiency In Basic Multiplication Facts Through Strategy Instruction, Stacey Braddock

Electronic Theses and Dissertations

The purpose of this action research study was to evaluate my own practice of teaching basic multiplication facts to fourth graders. I wanted to see how focusing my instruction on strategies would help my students develop proficiency in basic multiplication facts. I chose this topic because Florida was in the process of shifting to new standards that encourage teaching for deeper meaning. I hoped this research would give my students the opportunity to make sense of multiplication on a deeper level, while giving me insight into how students learn multiplication. Through this study, I learned that students initially find multiplication …

The Effects Of Folding-In Of Basic Mathematics Facts For Students With Disabilities, Tamara D. Bertini, Dara Coffrey, Kristine D. Swain

Special Education and Communication Disorders Faculty Publications

Research in the area of elementary mathematics has been limited in recent years. Direct instruction methods, including drill tasks, have been recommended for elementary students who have mathematics difficulties. This project involves two studies that examined the effectiveness of a specific direct instruction intervention, Folding-In, on the math computation achievement of elementary students. Weekly Curriculum-based measurement (CBM) progress monitoring data, as well as achievement test data, were used to monitor the effectiveness of the intervention, with improvements noted in math fact fluency in both a university-based clinical tutoring and a classroom intervention setting.

If Mowat And Davis Are Correct, Then Teaching Is Hard: A Response To Elizabeth Mowat & Brent Davis, Kris H. Green, Bernard P. Ricca

Mathematical and Computing Sciences Faculty/Staff Publications

In lieu of an abstract, below is the article's first paragraph.

Mowat & Davis (this issue) present a model of learning mathematics that relies heavily on ideas from network (or graph) theory. The important questions (to us, at least) concern the dynamics of the nodes and links. Answers – even tentative ones such as we present here – to these questions lead to a second set of questions concerning the implications of these answers to teachers and researchers.

The Relationship Between Timed Drill Practice And The Increase Of Automaticity Of Basic Multiplication Facts For Regular Education Sixth Graders, Nelly P. Knowles

Walden Dissertations and Doctoral Studies

By the time students transition from elementary to middle school, many do not demonstrate mastery of recalling basic math facts. This 8-week quasi-experimental quantitative study, based in cognitive development and theories of the construction of memory, used a 3-level independent variable experimental design to determine if there was a relationship between teachers' implementation of timed drill practices and the students' level of automaticity with regard to basic multiplication facts in 9 sixth-grade, regular education math classes. The control group received no intervention, the first treatment group received weekly timed drill practice for 3 minutes, and a second treatment group received …
