Designed to help the teacher in presenting the material of unit nine's science-math strand for third graders, this supplement and ditto packet contains both group visual aids and seatwork activities for individual students. Notations in the teacher's guide indicate when the supplementary materials should be used. Concepts explored in the four kits…

Utilizing word problems relevant to the field of environmental health, this workbook presents a concept-oriented approach to competency development in 14 areas of basic mathematics: (1) the expression of numbers as figures and words; (2) the addition, subtraction, multiplication, and division of whole numbers, fractions, and decimals; (3)…

Studied schemes involved in solving two-step arithmetic word problems in (n=1824) elementary schoolchildren in Israel. Compound schemes and combinations of operations were found to affect the difficulty level of the problems. Appendix includes two versions of the test instrument. (Contains 17 references.) (MKR)

This paper presents a research study of children using on-screen manipulatives (objects represented graphically on the computer screen) in learning mathematics. The paper begins by offering the rationale for the use of manipulatives in mathematics education, an assessment of why manipulatives are not more commonly used in schools, and a discussion…

Presents a study of 87 second graders to demonstrate that achievement tests in primary mathematics emphasize pupil's lower-order thinking by comparing answers to interview questions from constructivist and traditionally instructed groups. Results indicated that constructivist instructed students demonstrated superior higher-order thinking on tasks…

This document contains a training manual and reading and math basic skills curricula for use in specific learning disability programs and/or with educably mentally handicapped and emotionally handicapped students. The training manual is intended to help special education teachers understand and use precision teaching. A brief history of the…

Each of the four kits in this teacher's guide to a Spanish science/math strand for first graders provides for the development of mathematical competencies needed to function in science. Instructional and assessment activities in the bilingual curriculum are pupil centered, and contents are designed to enable the child to develop skills in the…

Instructional and assessment activities in science and math for third graders are presented in this teacher's guide to unit nine. Focus, objectives and materials for each activity are in English and Spanish, while teacher instructions are only in Spanish. The unit's theme is "the nation as a community"; related to the theme are the four spiraling…

Instructional and assessment activities for unit seven of a science/math strand for Spanish-speaking students in grade three focus on the extended community. Activities support four spiraling questions on the elements, wants and needs, change occurrence, and results of change. For each activity, the focus, objective, and materials needed are…

Built around a theme of communities in the nation, this teacher's guide for unit eight of a science/math strand for Spanish-speaking children in grade three contains both learning and assessment activities. This unit addresses what the elements are, how needs and wants are satisfied, how change occurs, and what the results of change are. The guide…

The purpose of this curriculum guide is to assist Training Specialists to teach Adult Basic Education/General Education Development (ABE/GED) students intermediate skills in reading, English, and mathematics. The guide begins with an introduction (purpose, overview, adult learner characteristics, teacher type), curriculum policies, curriculum…

Proposes the use of literature to introduce new mathematical concepts. Presents a story to develop the concept of grouping, and follows with 11 activities related to the story in which students use dramatization and manipulative materials to develop new groupings, predict outcomes, validate their predictions, and discuss findings to develop the…

The second unit of instructional and evaluation activities for a science/math curriculum in Spanish developed for first graders make up this teacher's guide. Kits five-eight, each covering a period of two to three weeks, present science and math instruction around the family. The guide lists focus, objective, and materials in English and Spanish…

Recent research suggests that many middle school students approach mathematical story problems with strategies that are not based on possible meanings for the operations, yielding success for one-step problems, but providing a weak background for approaching algebra story problems. This document reports the findings and the materials developed by…

The Proceedings of PME-XI has been published in three separate volumes because of the large total of 161 individual conference papers reported. Volume I contains four plenary papers, all on the subject of "constructivism," and 44 commented papers arranged under 4 themes. Volume II contains 56 papers (39 commented; 17 uncommented)…
