The purpose of this project was to assess the degree to which the most popular method of calculating reliability of interval data, the I-I method, served the author's scientific purposes. Data were collected and analyses performed to assess the adequacy of I-I reliability scores in serving three functions: (1) as an index of how precise, clear,…

A comparison was made of the results of two locator tests, the Zip Test (ZT) and the Wide Range Achievement Test (WRAT), which were administered to 37 black migrant and resident pupils. The children were tested twice with each test: in early September and eight weeks after in November. Twenty-three children were taught by the Inquiry Method…

The thesis investigates the characteristics of effective teaching as perceived by students at the Naval Postgraduate School. Principal components factor analysis is used to extract the characteristics from observations on an 86 variable questionnaire form designed by Hildebrand and Wilson. The characteristics are then used as a basis for a short…

Studied was the relationship between the Attitude Toward Disabled Persons (ATDP) scale and the Attitude Towards Handicapped Individuals (ATHI) scale. These scales were administered to 82 college students. Also determined was the coefficient of stability of the ATHI using a test-retest after 2 weeks with 54 Ss. The ATHI scale was thought to be more…

The Student Evaluation of Teacher II (SET II), the new instrument presented in this manual, is designed for use in securing student evaluations of teachers below the fourth grade or, with disadvantaged students, through the sixth grade. The manual describes the history, nature, and difficulties of the student evaluation of teachers movement and…

This study was concerned with reliability and accuracy of measurement of clinical performance in operative dentistry. The influences on reliability and accuracy of the nature of the rating scale (that is, the number and the specificity of scale points), the extent of clinical experience of the rater, and the training of raters were investigated.…

The present study evaluated methods by which speech samples for equal appearing interval scaling of articulation defectiveness could be prepared with a minimum time expenditure. Ten public school speech therapists rated 40 one minute edited and 40 unedited speech samples on a nine point equal-appearing interval scale. The speech samples were…

Human performance reliability for tasks in the time-space continuous domain is defined and a general mathematical model presented. The human performance measurement terms time-to-error and time-to-error-correction are defined. The model and measurement terms are tested using laboratory vigilance and manual control tasks. Error and error-correction…

Project objective was development of an experimental form of the Test of Modality Aptitude in Reading (TOMAR). The TOMAR was designed to classify children as visual, auditory, or kinesthetic learners in reading, to have sound measurement characteristics, and to be suitable for administration to groups of children rather than to an individual.…

The reliability of coding problems associated with observation studies is discussed. The purpose is two-fold: a) to examine coding reliability by applying the profile method to two coding occasions separated by a lengthy time interval with the object of determining both within-occasion reliability (agreement) and between-occasion reliability…

Environment plays an influential role in behavior. There is, however, often a discrepancy between the intended academic environment (as expressed by the institution in a variety of ways), and that perceived by the students. In order to explore this discrepancy, which may exist between the intended and the perceived institutional press, it is…

Generally, ratings have notoriously low inter-rater reliabilities. Because of differences in orientation, background, and expectations, ratings are seldom made from the same point of reference; thus, many types of error mask the true rating variance. Guilford's technique identified most types of constant error by analysis of variance and then…

The results of an investigation into some special cases of the general "orthomax" formulation are presented. In particular, the effects of manipulating a parameter in this formulation on various aspects of factor solutions are identified through the use of four sets of data, varying considerably in size, and reliability and factorial complexity of…

A test of literary judgment which could be used to investigate some aspects of a student's discrimination and response to literature was constructed for this study. Each of the two forms of the test consisted of four parts--"Thematic Imitation,""Paragraph Selection,""Title Choice," and "Distorted Images." One form of the test was administered as a…

The suggestion that multiple-choice items can be converted to true-false items without essentially changing what the item measures and with possible improvement in efficiency is investigated. Each of the 90 four-choice items in a natural science test was rewritten into a pair of true-false items, one true, one false. The resulting 180 items were…
