The purpose of this study was to construct and validate a test of critical thinking ability. A preliminary form was checked for face validity by a panel of experts in reading. Item analysis of this form resulted in a final form consisting of four parts with three subscales each. This form, and tests of intelligence and general reading ability,…

This study attempted to answer the following three questions: 1) Do students of grades four through seven perform equally well on both syncretistic understanding and logical thinking? 2) Do boys perform as well as girls on these two types of thinking? 3) Do students whose parents have a higher educational level perform as well as students whose…

The instructional model (IM) that is the basis of this evaluation resulted from the merger of two major Learning Research and Development Center (LRDC) projects--the Primary Education Project (PEP) and the Individually Prescribed Instruction (IPI) project. This paper examines the Center's publications relative to the problem of evaluation of such…

This paper provides for the elementary school teacher an introduction to the problem of mathematics readiness. The first part outlines the four developmental stages as seen by Piaget, and the manner in which schemata develop through the process of assimilation and accommodation. The second part consists of seven Piagetian tasks which a teacher may…

Eleven studies made between 1958 and 1960 gathered information about the conditions under which children seek out television and under which TV has an effect on them. This book describes these studies and reports and interprets their results. In the first few chapters, some of the changes TV has made in the child's world are described, and…

THE RELATIONSHIP OF AUDITORY-VISUAL AND TACTUAL-VISUAL INTEGRATION TO INTELLIGENCE AND READING ACHIEVEMENT WAS INVESTIGATED. IN ADDITION, THE RELATIONSHIP OF THE TWO INTERSENSORY INTEGRATION TASKS TO EACH OTHER AND TO THE TYPE OF READING ERRORS MADE ON AN ORAL DIAGNOSTIC READING TEST WAS ALSO EXPLORED. THE SAMPLE WAS COMPOSED OF 121 WHITE…

The article describes a kind of intelligence testing which assumes that the potential of a "retarded performer" may be greater than his demonstrated knowledge, and therefore tests him in the process of learning. (CD)

This article describes a new testing method which can be used to screen learning-deficient children fast, reliably, and inexpensively out of any population of public school systems. (Editor)

Eleven to fourteen year olds judged the size of eight angles. Subjects were grouped according to reading ability and their nonverbal intelligence was measured. Significant differences in performance were found in relation to age and ability variables, and between the angle-size ranges of 0 to 90 degrees and 90 to 180 degrees. (Author/RD)

The Wechsler Intelligence Scale for Children, and the revised form of that measure, were administered to a sample of sixth grade pupils. Although the correlation between measures was high, scores on the revised form were significantly lower. (JKS)

Ability test scores were decomposed into district, class, and individual components. First-order factor analyses at the individual level showed the usual Primary Mental Abilities test pattern. Second-order analyses grouped the primary factors into one power and one speed factor. Decomposition of variances in multilevel educational research is…

This study investigated sex differences on the Wechsler Intelligence Scale for Children-Revised (WISC-R) subtests for retarded males and females who were matched in terms of WISC-R Full Scale IQ's. Sample consisted of 126 children. Evidence from the investigation indicated that a significant interaction effect existed between sex and subtest…
