This article describes how mathematics and science teacher educators collaborated to promote the use of high-level tasks and inquiry-based instruction in high school classrooms. Working with a colleague in the School of Arts and Sciences, education professors developed and team-taught a model inquiry-based lesson. Then teacher candidates were…

This study compared the performance of students with and without learning disabilities (LD) on a mathematics test using a standard administration procedure and a read-aloud accommodation. Analyses were conducted on the test scores of 625 middle and high school students (n = 388 with LD) on two equivalent 30-item multiple-choice tests. Whereas mean…

This research tends to make the experimental study on the mathematics teaching model of "situated creation and problem-based instruction" (SCPBI), namely, the teaching process of "creating situations--posing problems--solving problems--applying mathematics". It is aimed at changing the situation where students generally lack…

The purpose of this article is to describe Discourse Time (D.T.), a teaching practice that aims to integrate argumentative literacy, the third piece of the literacy puzzle, into math learning environments. Snapshots from a tenth grade classroom at Skyview Academy High School in Thornton, Colorado is used to paint a vivid picture of what D.T. looks…

This article examines the social nature of teachers' conceptions by showing how teachers frame the "mismatch" of students' perceived abilities and the intended school curriculum through conversational category systems. This study compares the conversations of 2 groups of high school mathematics teachers addressing the Mismatch Problem…

This paper addresses a central issue in secondary school geometry, namely the role of proof. In an integrated mathematics and science curriculum, the role of proof as a process of conjecturing, explaining, and justifying within a small-group setting is analyzed. Particular attention is given to the students' use of empirical evidence and algebraic…

Being open to new ideas is instrumental for the professional development of teachers. Using numerous case studies of prospective teachers' beliefs as a backdrop, this study investigated the tensions and struggles four prospective teachers encountered as they confronted the unfamiliar. Both the formation of their belief systems and the interactions…

This study, conducted in the Netherlands, examined the effects of a problem-solving program on students' problem-solving and metacognitive skills. The program consisted of four parts involving one or more aspects of problem solving in the content areas of proportions, geometry, numbers, and solving equations and inequalities. The experimental…

This paper reports on the technological aspects of an international study in which secondary students engage in authentic data inquiries involving the posing, sharing, and critiquing of statistical word problems. This paper focuses on investigating the use of Web-based intranets to enable schools to conduct collaborative statistical investigations…

Precalculus and Discrete Mathematics (PDM) is the sixth and final course in the secondary mathematics curriculum developed by the University of Chicago (Illinois) School Mathematics Project. During the 1989-90 academic year, a formative evaluation of the third field-trial edition of PDM was conducted among a volunteer sample of 9 high schools with…

This study examined achievement differences between algebra students taught with the non-traditional textbook developed by Saxon and those taught with a "traditional" textbook by Dolciani. Student absences, rate of turning in homework, and ability level were considered, as well as teachers' comments. One Algebra I section in each of…

Examined was whether within-class social comparison processes mediate the effects of ability grouping in mathematics on self-concept. The sample was 149 students in seventh-grade classrooms in two schools, one practicing within-classroom grouping and the other using between-classroom grouping. It was predicted that, among students who frequently…

The papers in this report represent the imagination, analysis, and experiences of many people involved in recent curricular studies in secondary school mathematics. It differs from reports that seek broad agreement on conservative, traditional curricula, representing instead the point of view of those working with emerging electronic technology…

The conference of which these are the proceedings was held in June-July 1982 at Williams College in Williamstown, Massachusetts. The purpose was to discuss the restructuring of the first two years of college mathematics to provide some balance between the traditional calculus-linear algebra sequence, and discrete mathematics. The volume contains…

This book is directed toward increasing students' ability to analyze problems and comprehend what they read and hear. It outlines and illustrates the methods that good problem solvers use in attacking complex ideas, and provides practice in applying these methods to a variety of questions involving comprehension and reasoning. Chapter I includes a…
