Although sampling has been mentioned as part of the chance and data component of the mathematics curriculum since about 1990, little research attention has been aimed specifically at school students' understanding of this descriptive area. This study considers the initial understanding of bias in sampling by 639 students in grades 3, 5, 7, and 9.…

Offers a field-tested stock market unit designed to develop mathematical skills involving fractions and decimals, basic understanding of the stock market, and hypothesis testing skills in real world situations. Includes tables displaying questions, tally sheets, and instructions, as well as a list of related activities. (MDH)

A study of the differences in achievement among Ottawa's grade 9 and 10 students taught in English and French in three subject areas (mathematics, geography, and history) in which suitable comparative measures were available had as subjects the students in 73 classes. The students in French-language classes were administered the test twice, once…

This research study reports on the effectiveness with which the New Educational Program (NEP), a modification and refinement of the Job Corps Programmed Learning System, can provide effective learning experiences for underachieving adolescents and adults in various settings, including two juvenile detention facilities, a ninth grade class of…

Asserts that students' opportunities to learn subjects can be organized into sequences that span grades and schools. Examines national patterns in opportunities for learning mathematics and science from grade 8 to grade 10. Finds that the level of mathematics in grade 8 is closely related to that taken in high school, but this is not true of…

Reports on conceptual understanding and solution strategies for percent problems of (n=31) students representing 2 ability levels from grades 5, 7, 9, and 11. Strategies evolved from intuitive to formal and increased in diversity with increasing age. Appendix includes concept and computation interview questions. (Contains 15 references.) (MKR)

Higher order cognitive development and success in the study of high school mathematics and science require an understanding of rational number concepts and facility with proportional reasoning and computation. Proportional reasoning is an essential schema for developing formal operational thought. This study involving 16 ninth-grade students was…

"Harvard Education Letter" is published bimonthly at the Harvard Graduate School of Education. This issue of "Harvard Education Letter" contains the following articles: (1) Telling Tales Out of Charter School: What Educators and Policymakers Can Learn from the Successes and Failures of Charters (Robert Rothman); (2) One Charter School's Formula…

Ninth-grade students' (n=90) responses to impromptu, in-class writing assignments were examined to evaluate students' understanding of mathematical concepts. Participating teachers benefited by seeing how students' writings may reveal misconceptions concerning mathematical concepts, skills, and generalizations. (MDH)

Item responses of 2,380 mathematically talented junior high school students (1,437 males and 943 females) were studied to determine gender differences, using the mathematical sections of the Scholastic Aptitude Test (SAT-M). Girls excelled on miscellaneous items and data sufficiency items but performed less well on algebra items than boys. (SLD)

This study investigated interaction and achievement in cooperative small groups in four junior high school mathematics classrooms. Ninety-six students learned a one-week unit on consumer mathematics in mixed-ability or uniform-ability groups. Students in mixed-ability groups scored higher on a problem-solving test than students in uniform-ability…

The Biomedical Sciences Program at California State University, Los Angeles (CSULA), is described. The federally funded program was designed to help economically disadvantaged students to pursue careers in biomedical sciences. The program provided academic support in mathematics, science, and English; study skills development; experiences in…

Describes a project that enrolled 36 secondary mathematics and science teachers to work cooperatively to plan a program to help integrate mathematics and science concepts. Thirteen ninth grade study units having a laboratory or demonstration component were developed, field tested, and evaluated. Teachers noted differences in using mathematics.…

This document is designed to help school personnel analyze their current curriculum for grades 9, 10, and 11 in terms of the Mathematics Common Curriculum for Oregon. The common curriculum goals are organized into nine content strands: (1) number and numeration; (2) appropriate computational skills; (3) problem solving; (4) geometry and…

This document provides teaching guidelines and student material for a unit intended for use in junior high mathematics, consumer, or home economics programs. Time allotment is from four to six hours of classroom time. The objectives of this capsule are to enable students to identify reasons for comparison shopping, recognize the opportunity costs…
