Reviews research that has led to new ways of understanding mathematical development in young children. Covers research on information processing theory and cognitive science. (BB)

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)

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)

Five geometry experiments with 127 Australian high school students found that guidance provided in a format requiring attention to two sources of information resulted in performance no better than that on conventional problems. A format not requiring split attention resulted in the superiority of worked examples over conventional problems. (SLD)

Illustrates some learning encounters for facilitating first graders' understanding of geometry. Describes some of children's approaches using Cuisenaire rods and teacher's intervening. Presents six problems involving various combinations of Cuisenaire rods and cubes. (YP)

Describes a model for teaching early algebraic concepts using manipulative materials for elementary school students. Presents a rationale for the model. Provides activities for solving algebraic equations using envelopes and counters. (YP)

Presented are three cases for intuitive understanding in secondary and college level geometry. Four ways to develop the intuition (physical experience, mutable manipulatives, visualization, and looking back) step are discussed. (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)

Described is how the faculty of a high school accepted the responsibility of helping students gain a better working knowledge of metric measures during National Metric Week. Day-by-day activities for a week are included. Eight references are listed. (YP)

Encourages classroom teachers to improve their students' reading and reasoning skills by helping them to interpret math problems correctly. (RAE)

This article discusses two data analysis methods: (1) Box plot; and (2) Outlier. Described are the procedures for drawing the two diagrams, wing median, quartiles, and highest and lowest values. (YP)

This study was undertaken to determine whether a biology preparatory course given at an urban community college was helping students to develop the proper skills and background necessary to successfully complete follow-up courses in biology. Data indicated a mathematics score was the main discriminator between pass/fail groups of the preparatory…

Compares IQ's, and reading, math, and writing achievement for low and high IQ learning disabled students. Finds that the mean IQ scores of both groups declined significantly over time in spite of the fact that reading and writing achievement scores remained stable, and math scores declined. (RS)

Describes study of elementary school children in Australia which was designed to determine their sequential knowledge of measuring length and to apply recent cognitive theories to predict the sequence of development of knowledge. Recent literature is reviewed, information processing skills are discussed, and skills required for measuring length…
