A study was conducted to examine the influence of visual complexity in a televised presentation on attention and learning among young children. (Visual complexity is defined as a composite variable that assesses the number of perceptual elements in a visual display and accounts for the extent of movement or activity in a scene.) Forty-eight…

This report on ability grouping or "streaming" in secondary schools is an overview of research on the subject done in schools in many different countries. Referring to an extensive bibliography, the author gives examples of conclusions reached through observation and experiment on the part of educators. The complexity of the subject is revealed by…

The concept of testing for partial knowledge is considered with the concept of tailored testing. Following the special usage of latent trait theory, the word valdity is used to mean the correlation of a test with the construct the test measures. The concept of a method factor in the test is also considered as a part of the validity. The possible…

Issues of concern to test developers interested in applying the Rasch model are discussed. The current state of the art, recommendations for use of the model, further needs, and controversies are described for the three stages of test construction: (1) definition of the content of the test and item writing; (2) item analysis; and (3) test…

In a study of differences and similarities between children's oral and written stories, 23 third grade pupils wrote stories about a given topic and then, two weeks later, told stories about the same topic. Analysis of the stories revealed five types of narrative structures, of which the most commonly used was a "situation-problem-solution"…

A bibliography and selected annotations of research on cognitive style are presented. The citations were retrieved from computer and manual searches of the literature. Selected items, based on their significance to research efforts, are organized around subject, method, and results of each study. Ten constructs are included: (1) field…

This document contains one of two assessment tools developed by Proect Proud Option, which developed and field-tested a set of student- and job-assessment instruments that provide a strategy for determining (1) the vocational skills required on a particular job; (2) the functional skill levels of a particular student; (3) a process to determine…

The development of alternative instructional activities for use in the basic writing classroom and a description and analysis of four levels of basic writing are the results of a study of basic writing teaching techniques. The linguistic concepts of immediate and transferred utterances and nominal-verbal pairing, and the work of L. Vygotsky on…

The reliability of multiple choice tests--containing different numbers of response options--was investigated for 260 students enrolled in technical college economics courses. Four test forms, constructed from previously used four-option items, were administered, consisting of (1) 60 two-option items--two distractors randomly discarded; (2) 40…

The feasibility of generating multiple-choice test questions by transforming sentences from prose instructional materials was examined. A computer-based algorithm was used to analyze prose subject matter and to identify high-information words. Sentences containing selected words were then transformed into multiple-choice items by four writers who…

Test items, all referencing the same instructional objective, are not equally difficult. This investigation attempts to identify some of the determinants of item difficulty within the context of a first course in educational statistics. Computer generated variations of items were used to provide the data. The results were used to investigate the…

A study was conducted to analyze and compare the job performance of civil service and military pavements maintenance workers and construction equipment operators. A military sample of 2,675 and a civilian sample of 1,974 were surveyed by means of a job inventory checklist and relative time spent rating method. Of the three job types that were…

The feasibility of inferring relative task difficulty values and relative task aptitude requirements for a variety of tasks in the General and Administrative work areas is discussed. It was established that there was a high positive relationship between relative task difficulty values, as designated by work supervisors, and the corresponding…

This study sought to determine if there is a change in information processing and channel capacity as the human organism grows older, and if this relationship is altered with a change in stimulus complexity and dimensionality of the stimulus presented. With the human organism considered as a communication system, the use of absolute judgments to…

The fleet performance of a small group of Project 100,000 (low aptitude) personnel was assessed by means of an evaluation form completed by their supervisors after the men had been on board for approximately seven months. The men had previously been trained for the Navy rating, Aviation Structural Mechanic S (Structures), AMS. The performance of…
