A Five-year Study of the First Edition of the Core-plus Mathematics Curriculum

The study reported in this volume adds to the growing body of evaluation studies that focus on the use of NSF-funded Standards-based high school mathematics curricula. Most previous evaluations have studied the impact of field-test versions of a curriculum. Since these innovative curricula were so new at the time of many of these studies, students and teachers were relative novices in their use. These earlier studies were mainly one year or less in duration. Students in the comparison groups were typically from schools in which some classes used a Standards-based curriculum and other classes used a conventional curriculum, rather than using the Standards-based curriculum with all students as curriculum developers intended.

The volume reports one of the first studies of the efficacy of Standards-based mathematics curricula with all of the following characteristics:

· The study focused on fairly stable implementations of a first-edition Standards-based high school mathematics curriculum that was used by all students in each of three schools.

· It involved students who experienced up to seven years of Standards-based mathematics curricula and instruction in middle school and high school.

· It monitored students’ mathematical achievement, beliefs, and attitudes for four years of high school and one year after graduation.

· Prior to the study, many of the teachers had one or more years of experience teaching the Standards-based curriculum and/or professional development focusing on how to implement the curriculum well.

· In the study, variations in levels of implementation of the curriculum are described and related to student outcomes and teacher behavior variables.
