Problems of obtaining a representative sample for a national survey are discussed, and the experiences of Educational Testing Service are used as examples of some methods used to cope with these problems. It is suggested that researchers: (1) capitalize on some existing program; (2) establish in the minds of the possible examinees and the possible…

In an examination designed by a medical specialty board, six tests were administered to groups of candidates for certification to investigate the feasibility of using videotapes of doctor-patient interactions to assess candidates' ability to note signs of potential physical disorders during a patient's physical examination and history taking, and…

Research was conducted regarding the lack of information about (1) the relations of open-closed mindedness (dogmatism, authoritarianism, and rigidity) to reactions to a social studies methods course; (2) the possible biasing effects of drawing samples of teacher education students from different groups, subcultural and educational; and (3) the…

Synthetic estimation is a statistical technique that estimates small-area statistics by combining national estimates of the relevant characteristics with estimates of other known characteristics of the small geographic area. The advantages of the synthetic estimation approach to local estimation are its intuitive appeal, its simplicity, and its…

The research design discussed here focuses on four major questions: (1) what the relative effectiveness of well-implemented "individualized" instruction vs. well-implemented "standardized" instruction for recipients of compensatory education in terms of reading achievement, mathematics achievement and classroom climate is; (2)…

The National Institute of Education is in the process of designing and conducting a study of compensatory education in accordance with the Education Amendments of 1974. Special attention will be devoted to examining the relative effectiveness of "standardized" versus "individualized" instructional programs. The stated purpose of this report is:…

Appendix A, "Data Analysis When Students Change from Smaller to Larger Schools between the Pre-test and Post-test of the First Year," discusses a methodological problem involved in planning the approximate number of questionnaires to be administered in program. Appendix B, "Estimates of Sample Sizes and Data Collection Costs," includes five…

This report contains estimates of hearing levels for children 6 to 11 years of age in the United States as determined in the second cycle of the Health Examination Survey, conducted during 1963-1965. A probability sample (N=7,119) was selected to represent the 24 million children 6 to 11 years of age in the noninstitutional population. Hearing…

Three common methodological problems in the analysis of observational data include: (1) failure to base degrees of freedom for the analysis on the appropriate sampling unit; (2) the validity of the design and data are inconsistent with the generalizations reached; (3) the statistic used to calculate coder reliability is often inappropriate and…

A general interest in attrition, or loss of units from a study, stems in part from the observation that the infrequency of attention to attrition exacerbates problems of data interpretation. As a substudy of the national evaluation of Project Follow Through, the potential biasing effects of attrition of subjects from the sites were investigated.…

The sample for the 1975 field test of the Barber Scales of Self-Regard for Preschool Children came from Episcopal schools distributed widely by geographical area. The instrumentation included, besides the self-regard scales, the Self-Concept and Motivation Inventory and the Minnesota Personality Profile II, plus a demographic questionnaire. The…

This study investigates the impact of cooperative learning and the impact of opportunity to interact with classmates on achievement and cross-handicap relationships. Results indicate that positive goal interdependence with collaborative-skills and academic group contingencies promoted positive relationships with nonhandicapped classmates, frequent…

To reduce problems in comparing gains in the rate of students who progress to the next level of education, a nonlinear transformation is recommended. Two such transformations, probits and logits, are presented. Log linear models are recommended for an appropriate statistical test of sampling error. (Author/GDC)

The National Household Education Survey (NHES) is a telephone survey of the noninstitutionalized civilian population of the United States that collects data on educational issues that are best explored through contact with households rather than with institutions. In the 1996 NHES (NHES:96) the topical components of interest were parent and family…
