A seriation task (assembling a set of nesting cups) was used in this study to examine developmental changes in young children's ability to restructure a situation. Forty young children, eight each at 18, 24, 30, 36, and 40 months of age, participated in the study. Each child was presented with five nesting cups and was told he or she could play…

It is argued that the current theoretical orientation of motor behavior research toward information processing is only at the descriptive level. An outline of requirements for motor behaviorists to discover the mental operations that precede motor performance is presented. It is suggested that unless basic knowledge is obtained on how movement…

Five orders of approximation to normal English prose were constructed; 5th, 10th, 25th, 50th, and 100th plus. Five cloze tests were then constructed by inserting blanks for deleted words in 5 word segments (5th order), 10 word segments (10th), 25 word segments (25th), 50 word segments (50th), and 100 word segments of five different passages of…

This manual is designed for use in inservice work with teachers preparing to use the Comprehensive School Mathematics Program (CSMP) in grades K-2, and as a resource guide for later use. In it, the nonstandard topics used in the CSMP primary program are developed through discussion and a variety of exercises. These topics include the minicomputer…

A digital simulation of a model for the processing of visual images is derived from known aspects of the human visual system. The fundamental principle of computation suggested by a biological model is a transformation that distributes information contained in an input stimulus everywhere in a transform domain. Each sensory input contributes under…

This paper reviews some recent research on the component skills necessary to learn to read by phonic techniques. The review is divided into four sections, each relating research on one of the skills necessary for novel word decoding. The four skill areas are: (1) learning invariant grapheme-phoneme correspondences; (2) relating the isolated letter…

Five activities involving an array of numbers called an even triangle are given. Properties of the triangle are listed and some generalizations are proven. (MP)

The study investigated WISC-R subtest pattern scores of 58 learning disabled children. The evidence indicates that the low subtest scores on Arithmetic, Coding and Information were characteristic of this group. The study did not support the Verbal-Performance discrepancies as useful in the diagnosis of learning disabilities. (Author)

Track cards are manipulative materials used to promote verbalization, spatial perception, eye-hand coordination, simple problem solving, and fun in doing mathematics. (JT)

Transformations are defined and described through many examples. Teaching aids and activities for teaching about transformations are suggested. (JT)

Paper squares, each divided into eight congruent triangles, can be used in a variety of activities introducing ideas related to symmetry, pattern, and geometric transformations. (SD)

Presented are the mathematical explanation of the algorithm for representing rational numbers in base two, paper-and-pencil methods for producing the representation, some patterns in these representations, and pseudocode for computer programs to explore these patterns. (MNS)

Seventeen visually impaired children, aged 7-11 years, were compared with sighted children on a test of facial recognition and a test of expression identification. The visually impaired children were less able to recognize faces successfully but showed no disadvantage in discerning facial expressions such as happiness, anger, surprise, or fear.…

A computer program is presented for the billiard ball problem. It can be integrated into a lesson on inductive reasoning and suggests several ways to do so. (MNS)

Investigates the relative influence of speech and pointing gesture information in the interpretation of referential acts among children averaging three and five years of age and adults. (HOD)
