As followup to research on how weighted grades affect admission decisions of private college and universities, this article presents findings on effect of weighted grades on admission practices in public colleges and universities. Majority of admission directors surveyed believed that high school grades should be weighted. (NB)

This report presents findings from the Enhanced Reading Opportunities (ERO) study, a demonstration and evaluation of two supplemental literacy programs that aim to improve the reading comprehension skills and school performance of struggling ninth-grade readers. The report, which is the second of three, focuses on the second of two cohorts of…

This document provides the executive summary of "The Enhanced Reading Opportunities Study: Findings from the Second Year of Implementation. NCEE 2009-4036." The full report presents findings from the Enhanced Reading Opportunities (ERO) study, a demonstration and evaluation of two supplemental literacy programs that aim to improve the…

This paper provides practical guidance for researchers who are designing studies that randomize groups to measure the impacts of interventions on children. To do so, the paper: (1) provides new empirical information about the values of parameters that influence the precision of impact estimates (intra-class correlations and R-squares); (2)…

This study sought to determine whether the use of standardized test scores contributes any useful information regarding First Time in College (FTIC) students' probable success at USF, using more detailed analysis of underrepresented minorities and women, who Micceri (2009) shows, experience substantial negative bias relative to males and whites on…

A rational approach to standard transformed scores which always results in the numerical to letter grade correspondence for any chosen hypothetical grade distribution model is developed. (Author/LMO)

Developed a hybrid procedure for number correct scoring that uses test item weights based on multidimensional item response theory and total test scores based on classical true score theory. Simulation results show that all scoring methods in the study generated estimated and true scores that were highly correlated, but the hybrid method resulted…

The scores on 2 distinct tests (e.g., essay and objective) are often combined to create a composite score, which is used to make decisions. The validity of the observed composite can sometimes be evaluated relative to an external criterion. However, in cases where no criterion is available, the observed composite has generally been evaluated in…

First year students' academic performance in three Life Science courses (Botany, Zoology and Bioscience) was compared. Pass rates, as well as the means and distributions of final marks were analysed. Of the three components (coursework, practical and theory examinations) contributing to the final mark of each course, students performed best in the…

This study investigated the convergent and discriminant validity of the high-stakes Florida Comprehensive Assessment Test (FCAT) in both reading and writing at grade levels 4, 8, and 10. The data from the 2006 FCAT administration were analyzed via traditional multitrait-multimethod (MTMM) analysis to identify the factor structure and structural…

The G index of agreement does not permit the use of various weights for its various items. The weighted G index described here, make it possible to use unequal weights. An example of the procedure is provided. (Author/JKS)

The cross-validated classification accuracies of three predictor weighting strategies (least squares, ridge regression, and reduced rank) were compared under varying simulated data conditions for the two-group classification problem. Results were somewhat similar to previous findings with multiple regression when absolute rather than relative…

For idealized item configurations, equal item weights are often virtually as good for a particular predictive purpose as the item weights that are theoretically optimal. What has not been clear, however, is what happens to the similarity when the item configuration's variance structure is complex. (Author/CTM)
