eric.ed.gov har udgivet: For the past five years, Vermont has been developing an innovative statewide assessment system in which portfolios of student work in mathematics and writing are a key element. The use of mathematics portfolios, particularly in elementary school, is a novel aspect of the assessment system. This study examines the elementary school mathematics portfolio assessment and its instructional impact by exploring the conceptions of problem solving, the knowledge of problem-solving strategies, the evaluation of problem-solving tasks, and the instructional practices of 20 fourth-grade teachers. Teachers indicated that the portfolio assessment program has enhanced their understanding of mathematical problem solving and broadened their instructional practices, but that they have encountered difficulty in understanding certain components of the reform and making the relevant changes. Teachers did not share a common… Continue Reading →

eric.ed.gov har udgivet: This paper reports the findings of a study that assessed the effect of two classwide instructional grouping adaptation strategies on the math performance of English-language Latino learners in an urban public school in the Southwestern United States. An ABAB within-case design was implemented over a 12-week period to contrast the effectiveness of these adaptation strategies on the math performance of 19 low-, average-, and high-achieving first grade Latino students (ages 6-8). All instruction was conducted in Spanish, with the exception of 35 minutes in which students received English-as-a-Second-Language instruction. In Phase A, students worked independently in small heterogeneous groups of 4-5 high-, average-, and low-achieving students. In Phase B, peer tutoring was used following a teacher-led instruction. Dyads included students with different performance levels; students in each… Continue Reading →

eric.ed.gov har udgivet: The interest-based curriculum materials are designed to correlate the subjects of English, math, science, and home economics in an effort to infuse academic skills into the world of work. The curriculum guide is designed for mathematics curriculum and is divided into 11 sections: orientation, whole numbers, common fractions, decimal fractions, percents, units of measure and measurement, the metric system, ratio and proportion, introduction to algebra and geometry, and personal business. The learning activities include: class work, inquiry team approach, discussion, displays, lectures, filmstrips, tests, and personal banking and tax procedures and forms. A bibliography completes the document. Each section is organized around objectives, activities, evaluative material (teacher and student), and instructional materials. (JB) Link til kilde

eric.ed.gov har udgivet: This teachers’ guide lists manipulative aids, audio-visual materials, and demonstration materials for use in the elementary school mathematics classroom. Organization of the guide follows that of the California Strands Report (1967-68), as represented by these nine strands of mathematical content: numbers and numerals, geometry, measurements, applications, statistics and probability, sets, functions and graphs, logic, and problem solving. Catalog numbers and addresses of suppliers for all equipment are included. (RS) Link til kilde

eric.ed.gov har udgivet: This volume contains three teacher-developed units for eleventh grade mathematics students. It serves as an introduction to logarithms, matrices, and functions. Units include statements of objectives, content discussions, worksheets, and exercises. In the logarithm unit the emphasis is on calculation, while in the matrices and functions units development and proof are considered as well. Related volumes in the series are SE 016 615, SE 016 617, and SE 016 618. (LS) Link til kilde

eric.ed.gov har udgivet: This document summarizes the work of the Math Curriculum Project at San Francisco State University. The project developed seven curriculum units for the middle school mathematics program, using microcomputers as a problem solving tool to foster mathematical thinking and develop insights into mathematical concepts. They also created a prototype telephone network that is both a message system and a curricular data base for activities in each unit. Finally, they developed a teacher training model from their experiences in piloting the materials. The report describes the objectives, methods and procedures, outcomes, and dissemination activities of the project. An overview of the units, a network manager manual, a message system user manual, and a list of talks about the project are appended. (MNS) Link til kilde

eric.ed.gov har udgivet: This article discusses the issue of defining and facing equity elementary mathematics classrooms. It is argued that teachers have difficulty facing the fact of inequity in classrooms and that a deep conversation about equity is often avoided because many people are uncomfortable with disagreement. Two strategies for promoting in-depth dialogue about equity are presented. It is concluded that educators must confront their personal beliefs and examine how they are affecting students’ lives and student performance. (MM) Link til kilde

eric.ed.gov har udgivet: This teacher’s guide was designed to accompany five student workbooks: Math Language, Understanding Word Problems, Using a Calculator, Estimation, and Solving Word Problems. The series was specifically developed for low achieving students. The teaching gradually progresses in difficulty, but concepts are presented in small chunks that students can successfully handle. Questions within the text repeatedly involve the students’ attention, and their learning is checked and reviewed within each lesson. Word problem situations reflect mathematical problems that students would actually do. Following suggestions for how to present and use the workbooks, the guide contains over 200 blackline master worksheets. A description at the bottom of each page states the concept being developed, and the corresponding unit and page in the student’s workbook. Separate introductions are provided for each… Continue Reading →

eric.ed.gov har udgivet: A set of parent-child math activities designed to help busy, working parents do math with their children as part of everyday situations such as cleaning up and making dinner included basic steps, variations, and information on working with children were developed for families with elementary grades children aged approximately 5 to 11 and distributed at a variety of workplaces to groups of parents who had differing occupations, education levels, ethnicity, and family structures. The activities had titles such as How Much is on the Floor?, How Much Longer?, What’s Fair?, How Much Do We Save?, Wish List, and Number of the Day. Seven parents were interviewed 2-4 weeks after they had completed the activities with their children and the ways in which they used and adapted the… Continue Reading →

eric.ed.gov har udgivet: A model for use in identifying assessment needs in association with teacher-made mathematics and science tests at the secondary level was developed. The model focuses on the identification and narrowing of discrepancies between teachers’ perceptions of their testing practices and actual practice. All 19 math and 16 science teachers at a 4-year high school in a mixed suburban/rural school district participated in the project. Subjects’ involvement consisted of completing a brief survey instrument and supplying their most recently administered unit or quarter test. Data from 35 questionnaires and 34 tests containing more than 1,400 items were analyzed. Results cover the nature of classroom assessment, characteristics of teacher-made tests, item formats, cognitive levels treated, quality of items, and teachers’ confidence in testing skills. Topics identified as important for… Continue Reading →
