There is a need for clarity regarding different research strategies in order to assess the relative contribution of each. Using the framework of the Facet Design Technique (FDT) for problem structuring, eight general research strategies are identified as they relate to measurement fidelity, representativeness of units, and treatment…

This study evaluated short-term manpower projection methods for the personal services and medical and other health services industries. An employer benchmark survey was used to estimate actual employment of cosmetologists, barbers, registered nurses, and licensed vocational nurses. Out of seven projection methods which were applied to the data,…

Albuquerque's Title I evaluation staff is in the process of generating a comprehensive local evaluation design because it considers the federally required product evaluation unsatisfactory. The required mean-gain comparisons were extended beyond the dimension of program to the dimensions of school, grade, and Title I instructor. This evaluation…

The concepts of credibility, attraction, power, and "homophily" (degree to which source and receiver are similar in certain attributes) have been investigated as independent and unrelated variables in the communication process. The authors seek to establish the relationship of these variables as subdivisions of the overriding concept…

To determine if the Convergence Planning Technique, designed to identify research components and organize them in a logical manner on a matrix for analysis, could be applied to vocational education problems in Wisconsin, questionnaires composed of problems identified through literature reviews and interviews were distributed to vocational,…

Several experiments investigating the relationship between frequency of testing and learning are reviewed, and features of design which could have influenced outcomes are discussed. A study on test frequency is presented, in which relevant variables, apparently not considered in previous research, are controlled. Results indicate that moderate…

The author summarizes the results of 133 studies designed to test approaches to teaching children to think creatively. While acknowledging criticisms that most of the studies use performances on tests of creative thinking and other creative school performances as criteria, he contends that the evidence which they provide can be extremely useful to…

Several studies have been done about Mexican Americans but, in the area of their mental health, "a scant dozen articles are worth reviewing." Since the literature has been consistent in reflecting that a low socioeconomic level combined with extensive use of Spanish lowers IQ test scores of Mexican Americans, these factors should be studied in…

A Reading Interest Group of representatives from predominantly black colleges of the country was established by the Southern Regional Education Board's Institute of Higher Educational Opportunity. Representing 15 institutions from the East and Midwest, this group met and attested to the fact that a major percentage of the failures of black…

The designs for measuring the effectiveness of personalized educational prescriptions in a pilot second-grade classroom for the first and second years are presented. The analysis of pretest and posttest data is also given. (See TM 001 363 for summary report of the project; for other related documents, see TM 001 160, 365-374.) (MS)

Campbell (l969) argued for the interrupted time-series experiment as a useful methodology for testing intervention effects in the social sciences. The validity of the statistical hypothesis testing of time-series, is, however, dependent upon the proper identification of the underlying stochastic nature of the data. Several types of model…

Attrition, or the loss of study subjects, confounds the subject identification process. Design attrition occurs when subjects initially involved in the study are excluded because of changes in study focus or rationale. Data collection attrition occurs when subjects are excluded because they were not contacted by the data gatherer, or because the…

Volume I of the First Annual Report of the National Day Care Study (NDCS) funded by the Office of Child Development presents an overview of the NDCS study, the background of federal involvement in day care, the day care policy issues being addressed, an overview of the study design and phases, uses and limits of study findings, and the results of…

Article showed that the average first year academic achievement of the English students in Arts and Science was higher than that of the Scots both in 1969-70 and in 1972-73. Author then canvassed three possible explanations in terms of national differences in ability, in age and in previous familiarity with the work of the first university year.…

Teachers are urged to formulate and carry out research with their students. (JH)
