Comparisons of majority and minority group regression lines for purposes of assessing test bias may, under certain conditions, be viewed as comparisons of conditional bivariate distributions. Where these conditions hold, findings should reveal parallel regression lines except for a special case. Given the conditions described, one implication is…

In a manner similar to that used in the orthogonal case, formulas for the asymptotic standard errors of analytically rotated oblique factor loading estimates are obtained. This is done by finding expressions for the partial derivatives of an oblique rotation algorithm and using previously derived results for unrotated loadings. These include the…

A series of eleven concepts, eight of which were presented in a teacher training course, were rated by 252 undergraduate education majors on 15 semantic differential scales at the beginning and end of the course in an attempt to assess changes in the factor structure of semantic space and changes in the connotative meanings of the concepts. Scales…

Variance reduction analysis is a simple method for determining the effect of inequality of cell size on analysis of variance calculations. The suggested procedure has three steps. (Author/CK)

An investigation of techniques used to maximize response rates was the purpose of this study. Variables included perceived threat of questionnaire, questionnaire length, cover letter approach, follow-up correspondence, stamped/unstamped return envelope, and anonymity. The sample comprised 4,608 college faculty. Three analyses of response rates…

Summarized in this pamphlet are the U.S. Office of Education grants for 1972 in the field of environmental education. Grants were made in each of the 50 States, the District of Columbia, Puerto Rico, and Micronesia. Among the 162 grants totaling $2,999,040.00, most were made under the Environmental Education Act (P.L. 91-516), though some were…

In response to the increasing social concern for the quality of the environment and its conservation, and the need to ensure that all pupils in their final years of schooling be brought to share that concern, teachers in Hertfordshire, England, have constructed an 'A' level curriculum or syllabus of environmental studies for the sixth form. Based…

An experimental course covering some of the fundamental principles and terminology associated with environmental science and the application of these principles to various contemporary problems is summarized in this report. The course involved a series of lectures together with a program of specific seminar and discussion topics presented by the…

Composed of data submitted by a variety of experts in the field, this book provides an introduction to air pollution control. It contains the proceedings of the American Chemical Society Symposium on Determination of Air Quality held in Los Angeles, California, April 1-2, 1971. Contributions from chemists, physicians, engineers, administrators,…

The stability of various item discrimination indices when a particular item assumes membership within different sets of items was investigated. Results suggest that when item discrimination is used as a significant factor in determing which items from several forms will be selected for inclusion in a test, the actual items selected are less a…

The use of narrative test reports overcomes the major barrier to understanding reports, understanding the language that is used. Early attempts to utilize the computer in generating narrative reports include: (1) Teaching Information Processing System (TIPS), involving periodic collection of information from students regarding courses, which is…

This report summarizes research activities of the State Research Coordinating Units during the second half of the 1972 fiscal year and includes a final analysis of the entire fiscal year. The purpose of the report is to facilitate exchange of information and reduce duplication of effort among the states by providing awareness of the research and…

A three-day conference on articulation was held with 35 teachers from 7 high schools and New River Community College. Five committees were formed--Business, English, Guidance, Math and Science, and Occupational--to consider problems and seek solutions. Each committee identified numerous problems that could be solved through articulation. Many…

This semiannual report summarizes research activities of the State Research Coordinating Units conducted under Section 131(b) of the Vocational Education Amendments of 1968 during the first half of fiscal year 1972. The purpose of the report is to facilitate exchange of information and reduce duplication of effort among the states by providing…
