Brl Diss FINAL GENERATIVE ADOLESCENT MATHEMATICAL LEARNERS: THE FABRICATION OF KNOWLEDGE by BRIAN R. LAWLER (Under the Direction of Leslie P. Steffe) ABSTRACT This dissertation is embedded in a deconstruction of the field of Mathematics Education in order to reconstitute the mathematics student as a generative mathematical learner. The purpose of the dissertation is to understand how generative adolescent mathematical learners (GAMLs) maneuver through their mathematics courses while maintaining such a disposition. As a result, an initial model of constitutive characteristics of the GAML emerged. A generative disposition is meant to characterize the learner as someone who operates mathematically in ways that reflect an internal sense of authority for knowing and a constructive orientation to the knowledge they come to know. Drawing upon the radical constructivist teaching experiment methodology, I conducted a poststructural qualitative inquiry of students’ experiences that may have informed a generative disposition, their orientation toward mathematical knowledge, and the role of schooling in the interactions of these students. I co-taught the mathematics classes of the studies’ three students during April 2005 and interacted with the students as both teacher and classroom researcher. Field notes served as a primary data source, with some classroom episodes and student interviews videotaped in order to aid in the retrospective analysis that followed. Case studies were first developed, and then used to enrich an initial definition of the GAML. The GAMLs of this study relied on their own thinking to come to know. Confirmation of their teachers’ judgments that they were competent thinkers was strongly evident. The three GAMLs demonstrated confidence in what they knew and in their potential to come to know. They considered that mathematics is a human activity and were mathematically interactive among their classroom peers. Further, they enjoyed a high social and academic status among their classroom peers. A disconnection was observed in the three GAMLs between observed classroom behavior and their observed generativity. In particular, they rejected schooling in various ways and engaged in deviant classroom behavior.

  • A Brief History of American K-12 Mathematics Education in the 20Th Century
    A Brief History of American K-12 Mathematics Education in the 20th Century Written by David Klein Published in: Mathematical Cognition, Edited by James Royer Copyright by Information Age Publishing, 2003 Introduction In January 1998, when U.S. Education Secretary Richard Riley called for an end to the "math wars" in a speech before a joint meeting of the American Mathematical Society and the Mathematical Association of America, he could not have known that within two years, the department he directed would become the focus of the very math wars he sought to quell. In October 1999, the U.S. Department of Education recommended to the nation's 15,000 school districts a list of math books, including several that had been sharply criticized by mathematicians and parents of school children across the country for much of the preceding decade. Within a month of that release, 200 university mathematicians added their names to an open letter to Secretary Riley calling upon his department to withdraw those recommendations. The list of signatories included seven Nobel laureates and winners of the Fields Medal, the highest international award in mathematics, as well as math department chairs of many of the top universities in the country, and several state and national education leaders.1 By the end of the year 1999, the U.S. Secretary of Education had himself become embroiled in the nation's math wars. Mathematics education policies and programs for U.S. public schools have never been more contentious than they were during the decade of the 1990s. The immediate cause of the math wars of the 90s was the introduction and widespread distribution of new math textbooks with radically diminished content, and a dearth of basic skills.

  • A Multi-Case Study of Elementary Classroom Teachers' Transitions to Reform-Based Mathematics Instruction
    AN ABSTRACT OF THE DISSERTATION OF Elizabeth Busch White for the degree of Doctor of Philosophy in Education presented on April 19, 2004. Title: A Multi-Case Study of Elementary Classroom Teachers' Transitions to Reform-Based Mathematics Instruction. Abstract approved: Redacted for privacy M. Higgins The National Council of Teachers of Mathematics published their vision of active, problem-centered instruction with a goal of conceptual understanding in 1989. Fifteen years after these reforms were proposed the changes are reflected in school policy and elementary mathematics curriculum, but only limited change has actually occurred in classroom instruction. With the belief that the classroom teacher is the key person affecting educational change, thiscase study examines the journey of five elementary classroom teachers as they transformed their mathematics instruction from traditional to reform-based, with thepurpose of identifying the key elements that influenced the changes. This is a multi-case study involving five elementary classroom teachers who have recently been the ecipient of the Elementary Presidential Award for Excellence in Teaching Mathematics. All of these teachers began teaching with traditional textbook programs and have changed their teaching to reform-based, problem- centered instruction. Over the course of two one-hour interviews each teacher told the story of his or her changes, explaining the influences, the key resources, the influential people, and the support they received in the process. The cases are individually presented; then all five are examined together in a cross-case analysis using a constructivist theoretical perspective. Three key elements were found to be influential in the teachers' change journeys. First, all five were self-motivated to make changes in their mathematics instruction.

  • Under the Direction of Dr. James Mcdowelle)
    ABSTRACT Kathy O. Barber. A PROGRAM EVALUATION OF THE LEARNING FOCUSED MODEL IN CRAVEN COUNTY (Under the direction of Dr. James McDowelle). Department of Educational Leadership, March 2018. This program evaluation was to provide guidance to school officials for future decisions regarding the Learning Focused Solutions Model. The program evaluation was conducted using the evaluation design by Daniel Stufflebeam called Context-Input-Process-Product (CIPP), which targets program improvement. The four areas examined in the evaluation are context, inputs, processes, and product. The guiding questions for the four areas are: What is the target population and its needs? What are the inputs and resources of the Learning Focused Solutions Model? How is the program monitored? How will the results of the monitoring be tallied? What are the End of Grade Test results during the third year of implementation? What are the results of the walkthrough data? The program evaluation found the target population of third through eighth grade students needed to improve proficiency scores in math. The following recommendations were provided as a result of this determination: (1) The evaluator does not feel the evaluation provided enough evidence to support continuing a district-wide requirement of the Learning Focused Solutions Model for math planning and instruction, therefore it is recommended to revisit the intended use of the Learning Focused Solutions Model. (2) A continuance of a high yield strategy use is recommended. (3) Development and implementation of a reliable monitoring tool for observing high yield strategies is recommended. (4) It is recommended Craven County educational leaders make a determination of its teachers’ ability to teach math content and provide professional development to those who do not understand the content.

  • Algorithms, Algebra, and Access
    Algorithms, Algebra, and Access Stanley Ocken Department of Mathematics The City College of the City University of New York September, 2001 Introduction Perhaps the most contentious dispute arising from recent efforts to reform mathematics education concerns the place of traditional arithmetic algorithms in the elementary school curriculum. Opposition to teaching algorithms, especially the one for long division, can be traced at least as far back as the National Council of Teachers of Mathematics (NCTM) 1989 Standards Document’s call for de-emphasis of formal manipulation skills [N]. Indeed, prominent educators, including Steve Leinwand and Constance Kamii, have proposed that the standard algorithms be banished from American classrooms because they undermine children’s understanding, performance, and even emotional well-being [K] [L]. None of these effects has ever been documented by a properly controlled experimental study using a statistically valid sample population. Most new curricula of the past decade were based on the 1989 NCTM Standards and did in fact de-emphasize the standard algorithms or omit them entirely. Although the year 2000 revision of the Standards advocated “investigating” some of those algorithms as one of several possible techniques of whole number calculation [N1], the practical effect of that apparent revision of perspective remains to be seen. This paper will argue unequivocally for the critical role played by the standard algorithms of arithmetic in students’ mathematical development and in their preparation for mathematics-based careers. To do so, it will address misunderstandings supporting the view that student-invented procedures and other alternative procedures provide a mathematically valid substitute for, rather than a pedagogically useful supplement to, traditional methods for whole number calculation [K][L][S].
