A statistical model is developed to analyze longitudinal data when both process error…

John B. Carroll's Model of School Learning is a paradigm which describes the degree of learning that takes place in school setting as a function of the time spent on a learning task divided by the time needed for its mastery. The components of opportunity and perseverance in Carroll's model have particular relevance to a form of school…

Instructional task variables of analytical explanation and sequence were studied in two experiments to assess the systems approach proposition of efficiency and effectiveness in concept learning. The independent variable of analytical explanation consisted of two components: a procedure for focusing the subject's attention on the critical…

The purpose of this report is to describe the results of a series of studies conducted on the relationships between census information and school achievement in the Chicago Public Schools. These studies were designed as an exploratory investigation to determine the extent to which grade-level achievement averages could be predicted using data from…

The understanding of the political behavior of school boards can be advanced by conducting factor analysis of the voting records of trustees. While the application of these methods is generally appropriate, differences in subject matter highlight the problem of inferring political theory from numerical data. In this paper, several different…
