Sixteen third grade students, 16 college students, and 16 older adults performed a lexical decision (word-nonword) task to determine age-related differences in the magnitude of contextual priming effects. Context length and target quality (intact versus degraded) were within subject manipulations. A significant Age X Context Length X…

This issue of "Investigations in Mathematics Education" contains: (1) 12 abstracts of research studies in mathematics education; (2) a list (by EJ number) of mathematics education research studies reported in the July-to-December 1984 issues of "Current Index to Journals in Education" (CIJE); and (3) a list (by ED number) of…

A developmental investigation of the ability to control variables was conducted. One or two logically similar physics problems were individually administered to 120 subjects age 12 to 14. The problems involved either familiar or unfamiliar variables. Each problem was presented in three different informational formats. Success on the problems in…

An attempt to train concrete operational fifth-grade students (N=32) and seventh-grade students (N=32) to perform at the formal operational level on tasks demanding the control of variables are reported. The training was conducted in four individual sessions of approximately 30 minutes each. The training sessions were designed to represent a…

Several studies that were directed towards examining the influence of cognitive factors in sex-related differences in mathematics achievement are reported. Specifically, two lines of research were pursued examining: (1) the relationship between different types of visual-spatial skill and mathematics achievement, and (2) the trainability of…

This study investigated the relationship between children's ability to conserve on Piagetian tasks and six measures of the openness of classrooms which comprise the Dimensions of Schooling Questionnaire (DISC): (1) individualization of instruction; (2) student independence; (3) environmental flexibility; (4) nongradedness; (5) flexibility of…

A discussion of word acquisition rates and strategies is based upon a 6-month case study of an Estonian-speaking child who gradually and systematically relaxed phonotactic constraints to allow greater complexity in word production. In addition to the cognitive tools of assimilation and accomodation as described by Piaget, the child used a further…

The application of a scientific attitude to the field of education is reviewed, with particular regard to the varying perspective concerning the cognitive development and learning processes of children. Flaws in the "top-down" system of research and information dissemination, in which universities are viewed as "producers" and…

This three-volume report deals with the hypothesis that males are more successful at solving mathematical and spatial problems than females. The general relationship between visual spatial abilities and mathematical problem-solving ability is also investigated. The research sample consisted of seventh graders. Each pupil took five spatial tests…

This paper describes seven interrelated studies concerned with children's understanding of sequential actions and with the effects of observing a model on this understanding. A total of 546 elementary and secondary school students served as subjects for the studies. The tasks for all of the studies involved deriving the pattern for a sequence from…

A series of five experiments was designed and administered to 679 elementary and junior high school students over a 2-year period to test the relevance of Jean Piaget's concept of conservation to musical learning. Musical tasks consisting of stimulus patterns and systematic variations of these patterns were designed for each experiment, and…

IN PHASE I (OF THREE) OF A RESEARCH PROJECT, 475 SOUTHERN DISADVANTAGED CHILDREN (RANGING IN AGE FROM 3 TO 6) WERE TESTED IN AN INVESTIGATION INTO THE DESCRIPTION, DEVELOPMENT, AND SEQUENCING OF COGNITIVE ABILITIES DESIGNED TO YIELD INFORMATION ON CHILDREN'S LEARNING WITH IMPLICATIONS FOR TEACHING AND CURRICULUMS. COGNITIVE TASKS WERE SELECTED…

Theoretical and empirical research derived from Piagetian theory is collected on the intellectual development of the elementary school child and his acquisition and utilization of conservation concepts. The articles present diversity of method and motive in the results of replication (validation studies of the description of cognitive growth) and…

Representational competence refers to the individual's capability to respond appropriately to external representations. For example, a child engaged in a grouping task may collect together all like objects even if the group contains varying representations of the object, including (1) the object itself, (2) a three-dimensional likeness of the…

This teaching manual is the fourth in a series of seven (accompanied by a manual of self-assessment units) that have been designed for use in bilingual/bicultural programs. The components of the series may be used either individually or together. This manual is intended to familiarize teachers with ways of measuring cognitive styles in children.…
