In this paper, we focus on approaches in network dimensioning where it allocates bandwidths and attempts to provide a proportionally fair treatment of all the competing classes. We will show that an achievement function can map different criteria onto a normalized scale subject to various utilities. The achievement function can be coped with the Ordered Weighted Averaging method. Moreover, it m...

Classroom environments considered to be technology rich tend to show little difference between male and female achievement outcomes in the science classroom. This study investigates the effects of internet-based chemistry simulations viewed through the lens of gender in a high school chemistry classroom. This study examines 201 students enrolled in a chemistry class nested in an urban high scho...

This commentary discusses the Bauer and Curran (2002) investigation of growth mixture modeling. Single-class modeling of non-normal outcomes is compared to modeling with multiple latent trajectory classes. New statistical tests of multiple-class models are discussed. Principles for substantive investigation of growth mixture model results are presented and illustrated by an example of high scho...

We examine the achievement gap between low-income minority students in inner city (high-poverty) schools and their white high-income counterparts who attend suburban (lowpoverty) schools. Our data include the 4 and 5 grade math and reading scores for over 15,000 students in a large urban school district. We use a multilevel model to show that school resources do matter. We find that high qualit...
