Sampling for Phase I of the IGE Evaluation. Working Paper No. 223. Report.
Price, Gary G.
This paper is one of a group that describes the research methodology for an evaluation of individually guided education (IGE) in American elementary schools. Described here are the procedures used to select the sample of schools being studied in the first phase of the evaluation. This phase was a large sample study that used structural equations methods to examine relations between certain features of IGE schools and both pupil and staff outcome variables. The document also describes both the population of IGE schools and the sample, thereby providing an objective basis for judging the representativeness of the sample. A sampling procedure based on stratified random sampling was chosen to assure that the sample would reflect the full range of variability of IGE schools with respect to characteristics measured by the IGE Schools Questionnaire of March 1976. However, too few of the randomly selected schools agreed to participate, so it became necessary to request the participation of schools not initially selected. The sampling frame developed for stratified random sampling then was used to gauge how well the participant schools represented the total population despite the dangers of self-selection. A lengthy appendix contains the IGE Schools Questionnaire and tables of stratification variables. (Author/JM)
