This article describes the students' academic progress in an online course of business statistics through interactive software assignments and diverse educational homework, which helps these students to build their own e-learning through basic competences; i.e. interpreting results and solving problems. Cross-tables were built for the categorical…

Purpose, scope, and method of study. The purpose of this study was to compare the effectiveness of eighth-grade single-gender classes with coed classes across subject area, gender, at-risk status, and socioeconomic status (SES). The sample was drawn from one school, DeSoto West Junior High School, where enrollment averages 80% African American,…

There is an underlying assumption that regardless of student ethnicity, socio-economic status, or any other variable, elite, independent schools by mission and design are effective at producing successful students. This would cause some to conclude that all students enrolled in elite, independent schools perform similarly on all academic measures.…

Early childhood special education (ECSE) (Part B/619) services are intended to enhance the cognitive, social, and behavioral development of children with disabilities by meeting the needs of children with a disability and their family. Little is known, however, about the relationship between ECSE services and early school performance. How ECSE…

Groups of mathematically strong and weak second-, fourth- and sixth-graders were individually confronted with numerosities smaller and larger than 100 embedded in one-, two- or three-dimensional realistic contexts. While one third of these contexts were totally unstructured (e.g., an irregular piece of land jumbled up with 72 cars), another third…

A longitudinal research study was conducted at a public university in Pennsylvania on a sample of 129 at-risk students from a state-funded program (Act 101) designed to provide support services for economically and educationally disadvantaged students. This research employed a non-experimental, ex post facto methodology to assess the impact of…

When the highest-way association is present in a 3-way cross-classification of frequencies, standard logit and loglinear models have an many parameters as there are cells in the table; that is, the models are "saturated." Extensions of logit and loglinear models are described here that provide more parsimonious alternatives to saturated…

The technique presented accomodates multiple populations and a mixture of variable types. It is based on the linear discriminant function and the sequential concept. Also presented is an example in which the technique is used to obtain the classification rule to predict the career choices of individuals based upon a mixture of variable types.…

A theorem of Spjotvoll (1972) was used to determine and apply a confidence interval for the difference of two multiple correlations based on observations from a single sample. Spjotvoll's method of comparing regression functions is also applicable to a comparison of dependent multiple correlations, an unsolved problem posed by Hotelling in 1940.…

Lord's relatively unknown formula, based on the expected cross-sample, is shown to be superior to either of Wherry's formulas, which are based on the expected universe. (GS)

Multilevel analysis is an appropriate tool for the analysis of hierarchically structured data. There may, however, be reasons to ignore one of the levels of nesting in the data analysis. In this article a three level model with one predictor variable is used as a reference model and the top or intermediate level is ignored in the data analysis.…

The purpose of this study was to examine the relationships among college age student's experiences in close friendship, emotional autonomy and reasons to live. This study was grounded in Attachment Theory and College Student Development. A sample of undergraduate students was drawn from one Southeastern U.S. university. A total of 441 participants…

This quantitative study investigated the perceptions of principals, guidance counselors, and site facilitators in city/suburb, town, and rural schools concerning the Louisiana Virtual School (LVS). This study provided a benchmark of attitudes from school personnel about the LVS. The non-experimental research design used an online survey adapted…
