Activities for enhancing students' understanding and interpreting of graphical information is provided. Four worksheets and answers are given. (YP)

Presents 12 problems for students to investigate the relationships involving properties of numbers by using BASIC language. (YP)

Problem solving by example is an intermediate step toward mastering problem-solving heuristics. Discussed are problem-solving processes by using two problem examples. Emphasized are heuristics cataloging in a problem-solving log, and approaches to solutions, not the solutions themselves. (YP)

Describes a Mathematics Diagnostic Program to help teachers develop the skills to implement the diagnostic teaching model developed by Larson (1984). Reports the evaluation of the program by the participants, teaching assistants, and principals. (YP)

Outlines an instructional plan working within the existing structure of most colleges that produces higher levels of student achievement through the manipulation of time. Described are the objective-based unit design, group instruction, initial test, corrective procedures, and retest. Lists 10 references. (YP)

This paper compares the performance of China and the United States at the high-school-level International Mathematical Olympiad, focusing specifically on the United States' short training period and lack of women team members. Ways in which the United States benefits from Chinese mathematical talent are described. (JDD)

Illustrates an activity used in the classroom to reteach previously learned concepts, to review a unit, to introduce a vocabulary, to practice estimation, or to improve number sense. Provides three sets of game cards and explains how to use them. (YP)

Presents four worksheets designed to introduce middle school students to the use of diagrams to solve real world problems. Describes instructional usage of the worksheets with answers to all worksheets. (YP)

Classifies children's solution strategies by degree of abstraction and by use of physical objects. Children in grades one, two, and three were given two multiplication and four division word problems that differed in semantic structure. (Author/YP)

Investigates to what extent contextual changes in the meaning of the concept of "week" causes problems for children in the fifth and sixth grades. Reports that poor performing children have difficulties in finding the proper semantic referent. (YP)

Examines the students' understanding of mathematical structure and the relationship between problem solving and the identification of the structure in 13 word problems. Multidimensional scaling and hierarchical cluster analysis were used to assess how subjects organized word problems in their minds. (YP)

Provides guidelines for developing and implementing lessons using selections from children's literature as meaningful and appropriate contexts for solving word problems. Selection procedures, materials for constructing the characters, and two sample problems are provided. Lists 15 references. (YP)

The relationship between characteristics of test takers and characteristics of test items was examined in a quasiexperimental study involving 301 high school juniors and sophomores taking a mathematics examination that was consequential to sophomores but not juniors. Results are interpreted in relation to the expectancy value model of motivation.…

Suggested are ways to improve the SAT and its face validity. Suggestions include greater emphasis on more-realistic problems, inclusion of realistic percent problems, modification of the multiple-choice format, and the use of the National Council of Mathematics "Curriculum and Evaluation Standards" as a guide to construct the test. (MDH)

This study, with 66 regular classroom children and 52 children with learning disabilities, found high correlations among the Cognitive Levels Test, the KeyMath-Revised measure, and the Woodcock Reading Mastery Tests-Revised. Overall, 81 percent of subjects were correctly classified using the three-instrument battery. (Author/DB)
