Crossroads in Mathematics

Preface

Mathematics programs at two-year and four-year colleges as well as at many universities serve students from diverse personal and academic backgrounds who begin their postsecondary educations with a wide variety of educational goals and personal aspirations. In addition to serving students who are prepared to study calculus, these mathematics programs must accommodate students who intend to study calculus but enter college unprepared to do so. They must also serve students who do not intend to study calculus. The career aspirations of some of these students are such that requirements for graduation and for job placement can be satisfied through the study of mathematics below the level of calculus. Mathematics taught at this level in two-year colleges and in the lower division of four-year colleges and universities is referred to in this document as "introductory college mathematics." This phrase will be used to include college algebra, trigonometry, introductory statistics, finite mathematics, and precalculus, as well as all courses presently characterized as developmental mathematics. Noncalculus-based mathematics courses for technical or occupational programs and mathematics courses for elementary teachers and those for liberal arts majors are also considered part of introductory college mathematics for the purposes of this document.

Introductory college mathematics constitutes a large percentage of the offerings at postsecondary institutions. The survey done in 1990 by the Conference Board of the Mathematical Sciences (Albers, Loftsgaarden, Rung, & Watkins, 1992) revealed the following data concerning students studying introductory college mathematics (enrollment in computer science is not considered in these data):

Of 1,295,000 students studying mathematics in two-year college mathematics departments,

In addition, approximately another 126,000 students were studying introductory mathematics in two-year colleges in departments other than mathematics departments.

In four-year college and university mathematics departments,

These statistics indicate that introductory mathematics courses serve the needs of more than half the students studying mathematics in college.

The need for change in mathematics education has been documented in several national reports issued in the past decade, and significant change has begun at several levels. The Curriculum and Evaluation Standards for School Mathematics (National Council of Teachers of Mathematics [NCTM], 1989) presents comprehensive recommendations for innovative approaches to curriculum and pedagogy for kindergarten through twelfth grade; A Curriculum in Flux (Davis, 1989) makes specific recommendations for the curriculum at two-year colleges; Reshaping College Mathematics (Steen, 1989) outlines a proposed undergraduate curriculum; Moving Beyond Myths (National Research Council [NRC], 1991) calls for dramatic changes to "revitalize" undergraduate education; and Everybody Counts (NRC, 1989) makes specific recommendations for changes in mathematics programs from kindergarten through graduate school. Furthermore, calculus instruction has been reformed at many institutions [see Crocker (1990) for a description of the development of calculus reform, Ross (1994) for a description of recent reform initiatives, and Tucker and Leitzel (1994) for an assessment of calculus reform].

Until now no group has attempted to establish standards for mathematics programs that specifically address the needs of college students who plan to pursue careers that do not depend on knowledge of calculus or upper-division mathematics, or those students who need calculus but enter college unprepared for mathematics at that level. Almost all postsecondary institutions offer introductory mathematics courses, but in two-year colleges these courses constitute over 80 percent of the offerings (Albers et al., 1992). The American Mathematical Association of Two-Year Colleges (AMATYC) is the organization whose primary mission includes the development and implementation of curricular, pedagogical, assessment, and professional standards for mathematics in the first two years of college. In this document, AMATYC, with assistance from other professional mathematics organizations, has undertaken the challenge of setting standards for curriculum and pedagogy in introductory college mathematics.

Building upon the reform efforts cited above this document presents standards that are designed for adult students, many of whom are underprepared for the study of college-level mathematics. The purpose of Crossroads in Mathematics: Standards for Introductory College Mathematics Before Calculus is to address the special circumstances of, establish standards for, and make recommendations about two-year college and lower-division mathematics programs below the level of calculus.

Three sets of standards for introductory college mathematics are defined in Chapter 2.

The Standards for Intellectual Development address desired modes of student thinking and represent goals for student outcomes. They include

The Standards for Content provide guidelines for the selection of content that will be taught at the introductory level. They include

The Standards for Pedagogy recommend the use of instructional strategies that provide for student activity and interaction and for student-constructed knowledge. They include

The chapters that follow interpret the standards in various program areas, discuss the implications of the standards in several areas of mathematics education, and provide the design for establishing a nationwide effort to disseminate and implement the standards. Illustrative examples of problems aimed at capturing the vision and spirit of the standards appear in the Appendix.

The standards included in this document reflect many of the same principles found in school reform [for example, see NCTM (1989)] and calculus reform [see Crocker (1990), Ross (1994), and Tucker and Leitzel (1994)]. However, they differ in some respects and focus on the needs and experiences of college students studying introductory mathematics. In particular,

Cover Design

The cover art, created by graphics artist Karen Meyer Rappaport, depicts two crossing roads. These roads serve as a metaphor for two intersecting national trends: a growing societal need for a citizenry with a sophisticated level of mathematical preparation and an increasing number of academically underprepared students seeking entrance to postsecondary education. The cube situated at the intersection represents the three dimensions of the standards--intellectual development, content, and pedagogy--that are intended to guide mathematics faculty along the way to reform.

Vignettes and Margin Notes

The vignettes that appear throughout the document are true stories that help give a human face to the issues the report raises. The margin notes are of two types: excerpts that emphasize key ideas, and quotes from experienced mathematics educators and students that support the views expressed in the document. The quotes were obtained from speeches, published materials, position papers, document reviews, and student reports. The unidentified quotes may be attributed to the Task Force.

Acknowledgments

Each of the groups listed in the front matter played an important role in the planning and development of this document. The work of the Planning Group led to the development of the project proposal. The National Steering Committee developed principles to guide the writing of the document. The Task Force, aided by the consultants, began development of the document at a week-long writing session in Memphis in June 1993. The Task Force chose some of its members to serve as a writing team to receive feedback on the draft and revise the document accordingly. The Advisory Panel members reviewed the final draft and offered suggestions for final revisions. We wish to thank the numerous reviewers whose perspectives were considered at each stage of development. A special thank you is extended to Daniel Alexander, Michael Davidson, Sheldon Gordon, John Jenkins, and Jack Rotman, who submitted position papers, quotes from which appear as margin notes. The Task Force wishes to thank Allyn Jackson for helping edit the final draft, and artist Karen Meyer Rappaport for designing the cover. We thank Addison-Wesley Publishing Company for contributing the artwork and Prentice Hall, Inc. for donating the page designs and copy editing.

This document is intended to stimulate faculty to reform introductory college mathematics before calculus. These standards are not meant to be the "final word." Rather, they are a starting point for your actions.
