Study examined the effect of individual goal-setting conferences on academic achievement and attitudes in an ongoing educational setting. (Author)

This study estimated a component of within-school variance which has been overlooked in policy research studies and program evaluations performed to date: the effect on pupil performance of different teachers within a single school or program. Results indicated that teacher effects accounted for 30 to 40 percent of within-school variance. (Author/…

An author of the 1966 USOE report titled "Equality of Educational Opportunity" discusses some of the criticisms leveled against the study. The most serious charge is that the study attempted to do too much. By analyzing resource inputs and levels of achievement and by trying to analyze the effects of various inputs on achievement, the…

A procedure for the detection of differential item performance (DIP) is used to investigate the relationships between characteristics of mathematics achievement items and gender differences in performance. Eight randomly equivalent samples of high school seniors were each given a unique form of the ACT Assessment Mathematics Usage Test (ACTM).…

The statistical properties of two methods of estimating gain scores for groups in quasi-experiments are compared: (1) gains in scores standardized separately for each group; and (2) analysis of covariance with estimated true pretest scores. The fan spread hypothesis is assumed for groups but not necessarily assumed for members of the groups.…

The utility of the biomedical model of adjusted statistics is demonstrated. The model is recommended for use by educational researchers to randomize subjects for a more accurate estimate of school programs' success or failure when compared across classrooms or other units. (Author/MH)
