Infants were tested at 5, 8, and 13 months of age for numerosity perception. Subjects observed displayed figures on a screen moving at constant speed with irregular trajectories and occasional occlusions. Results demonstrated that discrimination of units, and not of characteristic patterns, underlies numerosity perception. (BC)

Two studies examined understanding of notational representation among 3- to 5-year-olds. Children solved problems when shown cards with a picture or word indicating identity or a quantity indicator. In the easier condition, children had difficulty solving the problems as a function of their familiarity with the notation, suggesting weaknesses in…

Uses colored cube combinations to investigate surface area, volume, and axes of symmetry. (ASK)

This paper is concerned with the use of spreadsheets within mathematical investigational tasks. Considering the learning of both children and pre-service teaching students, it examines how mathematical phenomena can be seen as a function of the pedagogical media through which they are encountered. In particular, it shows how pedagogical apparatus…

Purpose: In recent years a significant number of intellectual capital (IC) metrics has been developed and applied in many organizations. However, there is still a strong need to specify the relations among the different categories of intellectual assets that exist in the context of small to medium-sized enterprises (SME), and to determine the way…

The books in this series provide an essential ingredient in the transition from concrete mathematical experience to the symbolic reasoning used in algebra. They aim to guide the student in building and extending manipulative patterns, collecting numerical data, and analyzing the results. The main objective of the activities in this book is for the…

An algebraic development of the Fibonnaci sequence, appropriate for use in beginning algebra classes, is presented. (SD)

Most social work professionals take it for granted that the more training one has, the better one can do the job. But the authors' research on assessments by both MSW and BA candidates yielded results that could seriously question that assumption. (Author)

A puzzle involving computation and pattern observation is described. (SD)

A sixth-grade teacher reports an incident in which an average student discovered a complex relationship between equivalent fractions. (SD)

A study is reported in which subjects were shown sentences, some of which they had read previously, after intervals ranging from a few minutes to 32 days. Results show that information about typography can be recovered for at least 32 days after initial reading. Implications are discussed. (Author/RM)

Developed to provide supplementary instructional strategies for reading teachers at the kindergarten level, this booklet presents the instructional module for completing patterns, a component of the Comprehensive Reading Program of the Chicago Public Schools. After an overview of the module, activities are suggested for the following areas:…

The relative importance of spatial-position as a memory aid in a block pattern reproduction task was investigated by analyzing the object-selection and object-placement strategies of 69 nursery school children. Subjects were given a task modeled on Piaget's assessment of Static Reproductive Images and Action that had been modified into a…
