RCML History The Research Council on Mathematics Learning, formerly The Research Council for Diagnostic and Prescriptive Mathematics, grew from a seed planted at a 1974 national conference held at Kent State University. A need for an informational sharing structure in diagnostic, prescriptive, and remedial mathematics was identified by James W. Heddens. A group of invited professional educators convened to explore, discuss, and exchange ideas especially in regard to pupils having difficulty in learning mathematics. It was noted that there was considerable fragmentation and repetition of effort in research on learning deficiencies at all levels of student mathematical development. The discussions centered on how individuals could pool their talents, resources, and research efforts to help develop a body of knowledge. The intent was for teams of researchers to work together in collaborative research focused on solving student difficulties encountered in learning mathematics. Specific areas identified were: 1. Synthesize innovative approaches. 2. Create insightful diagnostic instruments. 3. Create diagnostic techniques. 4. Develop new and interesting materials. 5. Examine research reporting strategies. As a professional organization, the Research Council on Mathematics Learning (RCML) may be thought of as a vehicle to be used by its membership to accomplish specific goals. There is opportunity for everyone to actively participate in RCML. Indeed, such participation is mandatory if RCML is to continue to provide a forum for exploration, examination, and professional growth for mathematics educators at all levels. The Founding Members of the Council are those individuals that presented papers at one of the first three National Remedial Mathematics Conferences held at Kent State University in 1974, 1975, and 1976.

Constructs within this framework were utilized to understand the student’s mental model, and it was ultimately determined that the student had constructed a formal mental model with regard to the order and value of integers. This formal mental model implies a coordination between the negative and positive integers within his mental number line schema. Introduction Historically, negative numbers have been stigmatized as difficult; noted mathematicians such as Diophantus and Pascal have erroneously declared it impossible to subtract a larger number from a smaller, due to their inability to conceptualize negative integers (Bishop, Lamb, Philipp, Schappelle, & Whitacre, 2011). Within the frame of modern mathematics, a negative difference is no longer problematic; however, its history is interesting because developmentally immature students today may harbor the same misconception as did Diophantus and Pascal (Bishop, Lamb, Philipp, Schappelle, & Whitacre, 2011). Despite the advances of modern mathematics, students’ misconceptions regarding negative integers persist beyond the onset of instruction (Murray, 1985). Bofferding (2010) suggests that while the whole number system can be built by students through interaction with appropriate manipulatives, no such manipulatives exist for negative integers, therefore making the extension of the integer system to include negatives markedly more

    Chapter 13 National Science Foundation Systemic Initiatives: How a small amount of federal money promotes ill-designed mathematics and science programs in K-12 and undermines local control of education Michael McKeown Mathematically Correct David Klein California State University, Los Angeles Chris Patterson Education Connection of Texas Since its inception in 1950, the National Science Foundation (NSF) has played a strong, positive role in making American scientific research and technological application the best in the world. Through its funding of peer-reviewed, investigator-initiated research proposals, it has supported basic research in a wide variety of scientific disciplines, such as mathematics, biology, physics, chemistry, geology, astronomy, and psychology. American science owes much to the support it has received, and continues to receive, from NSF. This chapter deals with a program in the Education and Human Resources Division called the NSF Systemic Initiatives Program, not with NSF programs related directly to the support of basic research. We are highly critical of this particular NSF program. Not only do the Systemic Initiatives undermine local control of education, but, as our analysis in this chapter suggests, they also seem to lower academic standards for mathematics education and weaken the educational base for American science. This chapter is composed of three sections. The first section, an overview of NSF Systemic Initiatives, was written by Michael McKeown. The second section, an analysis of the development and 288 Standards Wars features of the Los Angeles Systemic Initiative, was written by David Klein. The third section, an analysis of the development and features of the Texas Statewide Systemic Initiative, was written by Chris Patterson.

  • An Alternative Route to Teaching Fraction Division: Abstraction of Common Denominator Algorithm
    International Electronic Journal of Elementary Education, 2015, 7(3), 399-422. An Alternative Route to Teaching Fraction Division: Abstraction of Common Denominator Algorithm İsmail Özgür ZEMBAT Mevlana (Rumi) University, Turkey Received: February 2015 / Revised: May 2015 / Accepted: May 2015 Abstract From a curricular stand point, the traditional invert and multiply algorithm for division of fractions provides few affordances for linking to a rich understanding of fractions. On the other hand, an alternative algorithm, called common denominator algorithm, has many such affordances. The current study serves as an argument for shifting curriculum for fraction division from use of invert and multiply algorithm as a basis to the use of common denominator algorithm as a basis. This was accomplished with the analysis of learning of two prospective elementary teachers being an illustration of how to realize those conceptual affordances. In doing so, the article proposes an instructional sequence and details it by referring to both the (mathematical and pedagogical) advantages and the disadvantages. As a result, this algorithm has a conceptual basis depending on basic operations of partitioning, unitizing, and counting, which make it accessible to learners. Also, when participants are encouraged to construct this algorithm based on their work with diagrams, common denominator algorithm formalizes the work that they do with diagrams. Keywords: Teaching fraction division, abstracting common denominator algorithm, curriculum development Introduction Arithmetic operations, and teaching and learning of them have always been an interest for mathematics education community. In his historical analysis, Usiskin (2007) pointed out that operations (especially on fractions) still preserve its importance in school mathematics and they should be given enough emphasis.

  • Traditional Mathematics Teaching Is Still the Norm in Our Nation's Schools
    Forum on Public Policy Mathematics and Literature: Educators’ Perspectives on Utilizing a Reformative Approach to Bridge Two Cultures Suzanne J. Nesmith, Associate Dean/Assistant Professor of Education, Wayland Baptist University Abstract The existence of two distinct cultures within our society, the arts and the sciences, was introduced by physicist C. P. Snow in his 1959 Reed Lecture at Cambridge University and was further illuminated by Snow in The Two Cultures, a Second Look (1964). Lamenting the existence of the cultural chasm while also fearing a widening of the schism, Snow opened a dialogue with the hope of reconciliation between the cultures. Fifty years later, although the chasm still exists, numerous entities and individuals within the cultures work to formulate the means by which the cultures may be bridged, and, subsequently, the chasm narrowed and eliminated. The National Council of Teachers of Mathematics (NCTM) is one such entity, and leaders of the group have worked since the council‟s establishment in 1920 to research, promote, and improve the teaching and learning of mathematics through innovative, reformative approaches. Reform-oriented curricula are built upon constructivist perspectives aimed at assisting students in utilizing their own unique backgrounds and experiences to develop a personal understanding of mathematical situations. One means of infusing personal experience into the mathematics curriculum, while also bridging the aforementioned cultures, is through the incorporation of children‟s literature, yet there exists great variance in the type, format, structure, and success of the methodology‟s implementation. Subsequently, while the reformative approach of mathematics literature integration presents as a means of building understanding by bridging the cultures of mathematics and the humanities, it is the educator‟s choices relevant to the approach which have the greatest impact on the outcomes of the approach.

  • Review of Evaluation Studies of Mathematics and Science Curricula and Professional Development Models
    Abstract This report identifies mathematics and science curricula as well as professional development models at the middle and high school levels that are effective based on their success in increasing student achievement. The goal of the study was to provide some choice to districts and schools that wanted guidance in selecting a curriculum and that wished to use effectiveness as a selection criterion. Unexpectedly, most middle and high school mathematics and science curricula did not have studies of student achievement with comparison groups, and it proved especially difficult to find effects in either math or science for subgroups by sex, minority status, and urban status. Findings strongly suggest that science curricula is more effective when it is inquiry-based, although math curricula can be effective when standards- or traditional-based.

  • The Comparison of Physical/Virtual Manipulative on Fifth-Grade Students’ Understanding of Adding Fractions
    Running Head: COMPARISON OF PHYSICAL/VIRTUAL MANIPULATIVE The Comparison of Physical/Virtual Manipulative on Fifth-Grade Students’ Understanding of Adding Fractions A dissertation submitted to the Graduate School of the University of Cincinnati in partial fulfillment of the requirements for the degree of Doctor of Education in the Department of Curriculum and Instruction of the College of Education by Sami Alshehri M.A. Umm Al-Qura University July 2008 Committee Chair: M. Sally, Ed.D. COMPARISON OF PHYSICAL/VIRTUAL MANIPULATIVE ABSTRACT The purpose of this quantitative study was to compare two types of manipulatives in order to see their effects upon understanding of adding fractions for three comparable groups of fifth grade students. A total of 163 students who demonstrated low mathematical performance participated in the project in order to learn the addition of fractions by using physical and virtual manipulatives for the experimental groups and the normal mathematic curriculum for the control group. The intervention occurred during a two-week time frame in six public elementary schools in Abha, Saudi Arabia where students used fraction bars for both physical and virtual manipulatives in order to build conceptual understanding of adding fractions properly. Instructions were provided to all the participants directly regarding what the participants were to do each day of the 2-week experiment. Pre-and post-tests, an attitude survey, and a preference survey were the instruments that were used to collect data during the study. A repeated measures design with a cross over treatment was used for comparing the effects of the two modes of treatments, virtual and physical manipulatives, compared to a control group for the understanding of adding fractions for the three groups of students.

  • What Students Notice As Different Between Reform and Traditional Mathematics Programs
    Journal for Research in Mathematics Education 2008, Vol. 39, No. 1, 9–32 What Students Notice as Different Between Reform and Traditional Mathematics Programs Jon R. Star Harvard University John P. Smith III Michigan State University Amanda Jansen University of Delaware Research on the impact of Standards-based mathematics and reform calculus curricula has largely focused on changes in achievement and attitudes, generally ignoring how students experience these new programs. This study was designed to address that deficit. As part of a larger effort to characterize students’ transitions into and out of reform programs, we analyzed how 93 high school and college students perceived Standards-based and reform calculus programs as different from traditional ones. Results show considerable diversity across and even within sites. Nearly all students reported differences, but high-impact differences, like Content, were not always related to curriculum type (reform or traditional). Students’ perceptions aligned moderately well with those of reform curriculum authors, e.g., concerning Typical Problems. These results show that students’ responses to reform programs can be quite diverse and only partially aligned with adults’ views. Key words: College/university; Curriculum; High school (9–12); Integrated curriculum; Learners (characteristics of); Qualitative methods; Reform in mathematics education; Social factors One inevitable outcome of the development of new curricula in any field, but perhaps particularly in mathematics, is to provoke discussion and debate about what content can and should be taught in schools and universities. The recent cycle of The entire Mathematical Transitions Project team played a vital role in the work reported here. In addition to the authors, the other members of this team were, in alphabetical order, Dawn Berk, Carol Burdell, Beth Herbel-Eisenmann, Gary Lewis, and Violeta Rosca-Yurita.
