An experiment employing a 2x2x3 factorial design sought to determine the extent to which socially disadvantaged elementary school students' unfamiliarity with some terms in a verbal subsection of a group intelligence test may account for their relatively poor performance on such tests. Training was provided so as to attempt improvement in these…

To determine factors influencing the permanency of a protrustional lisp and to incorporate them into predictive profiles, approximately 8,000 kindergarten children were screened for articulation and those appearing to have a protrusional lisp were tested individually. The 1,043 subjects exhibiting such a lisp were examined semiannually for 4 years…

Since publication of the Coleman Report, the belief has become increasingly pervasive that formal education does not or cannot make a difference in what a student learns--that patterns of academic performance are immutably molded by social and economic conditions outside the school. The purpose of this paper is to present a comprehensive review…

How can school officials manage their responsibilities in ways that are likely to improve the quality of the product they provide? There is a logical sequence of activities. First, school officials must be able to diagnose where problems exist. Then they must learn to apply treatments systematically, to assess carefully the success or failure of…

In recent years there has been increasing interest in the effects of bilingualism on cognitive growth and on the bilingual's attitude toward himself and his 2 language communities. One of the most widely quoted studies on bilingualism is that of Peal and Lambert (1962) who dealt with the relation between intelligence, attitude, and achievement in…

The purpose of the Colorado Evaluation Project was to field test the Common Status Measures at grades four and eleven in conjunction with a statewide assessment program based on objective-referenced testing instruments developed by the Colorado Department of Education for grades kindergarten, three, six, nine, and twelve. The evaluation was…

Major purposes of the study were to: (1) determine the critical behavioral requirements for the generic job of Idaho Extension agricultural agent based on the analysis of critical incidents, and (2) study several situational factors related to critical incidents. Situational factors were: (1) most important subject content (social, technological,…

This review is one in a series intended to develop methods which maximize the use of the existing scientific literature as a basis for predicting human performance. It is concerned with sensory performance in target detection, defined in terms of the "probability of detection" of a flash of light. Two conditions of detection are…

The study was undertaken to compare the achievement of a group of fifth grade students studying anthropology from a programed text, designed by the investigator, with a group of fifth grade students being taught by means of traditional classroom material prepared by the Anthropology Curriculum Project of the University of Georgia. Post-treatment…

This study was designed to investigate the effectiveness of low cost instructional simulation, with numerical control (N/C) used as the subject vehicle. A unit of study was developed that included a detailed list of the behavioral changes which were desired for the students and the instructional materials and procedures deemed necessary for aiding…

Traditionally, studies investigating the relationship between mental abilities tests and performance on learning tasks have attempted to establish a direct relationship between these two domains by use of factor analytic techniques. It is suggested that an alternative approach can be formulated in terms of an information processing analysis of…

Visuals, like pictures, charts, diagrams, graphics, and the like, are widely used in education. However, there is little justification in the research literature for their use. The overall purpose of this exploratory study was to find out more about the processing of visuals or graphics in an educational task. Specifically, it was thought that…

This paper describes research findings which indicate that black students in competition with white students exhibit self-deprecating behavior. They devalue their performance relative to the performance of white students. A large percentage of these research findings are the result of work performed by Irwin Katz in small group settings. Katz and…

This document presents a model for a program to guide teachers in effective self-evaluation. In this structured program, the teacher is expected to write course, unit, and daily lesson plans incorporating behaviorally stated objectives, which communicate his or her instructional intent. With the help of a trained observer-evaluator, the teacher is…

In an attempt to selectively improve student performance, one-half of a set of difficult test items from a FORTRAN programming class had handouts explaining the concepts underlying the items distributed to the students. Each handout contained a written learning objective, a short prose passage explaining the objective, and one or more practice…
