Previous research has indicated that correlations between Piagetian and psychometric tests and chronological age are influenced by the size of the age range of the sample groups. To examine whether the size of the age range and mean age are related to the size of the correlations between Piagetian and arithmetic tests, Spearman rank-order…

This book is designed to assist the teacher in providing children with creative learning experiences in mathematics. Though these experiences are considered appropriate for a wide range of ages and grade levels, they have been assembled for pupils in grades 5 through 9. The material contained in this book was developed as part of an extensive…

A Head Start research report on ways to improve academic achievement of disadvantaged children describes five projects: (1) a study of sociolinguistic variables in school learning and problem solving when classes are taught in dialect versus standard English; (2) subcultural determinants of cooperative and competitive behavior in preschool…

A test of problem solving behavior which provides information about the mastery of the prerequisites of the problems has been developed for fourth grade children. Each problem solving question is preceded by two other questions which assess the child's understanding of the information contained in the actual question, and an application question…

This sourcebook is an example of how environmental concepts can be introduced into various areas of the school curriculum. Included are a series of problems, projects, and exercises for students in grades four through ten. They are concerned primarily with pollution, population, individual needs, industrial needs, and consumption, on both a…

This demonstration project provides intensive instruction in reading and mathematics to selected fifth graders in the 1974-75 year and for selected fifth and sixth graders in 1975-76 in order to raise the reading and mathematics performance of underachievers to a level commensurate with measured ability. The sharing of learning activities in…

This study was designed to test the effectiveness of providing students with instruction on how to use the information contained in examples and non-examples of disjunctive concepts, and of five different instructional sequences of examples and non-examples. Students (192) enrolled in a mathematics course for prospective elementary teachers served…

The development of an instrument for evaluating cognitive growth in preprimary children by means of observational techniques is reported. Areas of growth in pre-mathematic skills were defined for this purpose as: Imitating, recognizing, classifying, matching, comparing, understanding, counting, computing, and measuring. Each is described, and…

The suppressor variable, a variable wholly uncorrelated with a criterion, but which nevertheless improves prediction because of its relationship with a predictor, is critically examined. For a suppressor so defined, formal identities are shown with part, partial, and multiple correlational procedures. It is demonstrated that if maximum prediction…

This preschool program offered a highly structured curriculum in which language development was fostered through encouraging verbal responses in a game format context. The curriculum, based on skills and concepts required for success in elementary school, included language arts, reading readiness, mathematical concepts, science, and social…

Duncan's interpretation of his research on the nature and process of the distribution of rewards in the U.S. stratification system is questioned. Statistical and conceptual flaws are noted in Duncan's work and their implications explored. A reanalysis of primary survey data is presented and, based on a reinterpretation of this data, a…

GRADES OR AGES: K-6. SUBJECT MATTER: Mathematics. ORGANIZATION AND PHYSICAL APPEARANCE: There are three chapters: 1) Scope and Sequence--the spiral approach to learning, using the scope and sequence, scope and sequence charts, and glossary for teachers; 2) objectives in Mathematics--behavioral objectives for elementary mathematics and evaluation…

Discusses the interactions of several students involved in a Dutch research project studying student achievement in elementary school mathematics. Results showed progress by most children, particularly those with low scores on the pretests. (TW)

Presents an introduction to the study of projective geometry, including a definition and some analagous examples using the overhead projector. Illustrates the principle of duality, Desargues' theorem, Poppus' theorem, and Pascal's theorem. (TW)

Describes how Logo has been used to introduce primary children to mathematical concepts often considered to be too difficult for them. Outlines how Logo has been used to introduce the estimation of distance, the estimation of angles, symmetry, rules of precedence, the concepts of random, and the use of variables. (TW)
