Many times in both educational and social science research it is impossible to collect data that is complete. When administering a survey, for example, people may answer some questions and not others. This missing data causes a problem for researchers using structural equation modeling (SEM) techniques for data analyses. Because SEM and…

Purpose: The purpose of this research was to disclose the psycho-semantics of the opinions held by school educators in Lithuania on the expression of democracy in education management. Methodology: A non-standardized questionnaire asked teachers the open-ended question: "Are there any manifestations of democracy in your school? If yes (or…

This study sought to address the lack of experimental research examining the influence of contextual factors on African American students' learning. A total of 162 low-income African American and White fourth graders were randomly assigned to ethnically homogeneous, communally structured groups of three to work on a motion acceleration task using…

In this paper, we conceptualize and develop an index of sociodemographic risk that we hypothesize will be an improvement over the standard poverty measure as a measure of risk for children's development. The poverty line is widely used in government statistics and in research but is also widely acknowledged to have multiple shortcomings. Using…

A growing body of research has linked exposure to violence to violent behavior, but few studies have examined the impact of the timing of exposure to violence on violent behavior among inner city, minority youth. Theoretical insights derived from developmental psychology and psychopathology (DPP) and Agnew's general strain theory (GST) give…

This final report describes a 3-year federally funded project designed to conduct an analysis of the factors that contribute to the performance of high intensity problem behaviors by students with severe disabilities. The project utilized a series of five integrated studies, which involved students with severe intellectual disabilities and the…

The Schools and Staffing Survey (SASS) is a periodic, integrated system of sample surveys on elementary and secondary schools in the United States that collects information on school and district administrators and teachers in public and private schools. This technical report is one in a series of methodological studies relating to the SASS of the…

A study was undertaken at a large, ethnically diverse community college in California to identify instructor and course factors associated with grade variability and grade differences by gender and race/ethnicity in mathematics courses. The study used a statistical procedure called hierarchical linear models (HLM) to analyze the relationship…

Several goodness of fit (GOF) criteria have been developed to assist the researcher in interpreting structural equation models. However, the determination of GOF for structural equation models is not as straightforward as that for other statistical approaches in multivariate procedures. The four GOF criteria used across the commonly used…

This study examined the impact of word processors on the writing of eighth grade students experienced in computer use. Four classes of students (n=111) were asked to write one expository paper on the computer and another paper on a similar theme by hand in a repeated measures research design that controlled for effects of order of writing (on or…

This paper presents a framework for understanding conditions of discovery learning in computer-based microworlds. It begins with a short discussion of problems related to a traditional type of microworld--i.e., learning tools for mathematics--using the Dienes Multibase Arithmetic blocks as an example. In this discussion, hypotheses are developed…

This study investigated continuing motivation for hard and easy tasks and subjects' judgements of selected learner characteristics purported to be related to learning and motivation. The data were collected through subjects' self-reports on a Student School and Work Survey questionnaire. The subjects were approximately 100 males and 100 females…

Field tests on an interpersonal skills instructional program, the Heartsmart Adventures, were conducted for the formative and summative evaluation in 14 classrooms in 7 schools of 394 students in grade 4 classes. The results indicate that the Heartsmart program is likely to provide an appealing, educationally relevant and worthwhile experience to…

A latent trait model is described that is appropriate for use with tests that measure more than one dimension, and its application to both real and simulated test data is demonstrated. Procedures for estimating the parameters of the model are presented. The research objectives are to determine whether the two-parameter logistic model more…

This study examined the efficacy of Judith Langer's PreReading Plan (PReP) with Hispanic and other high school students. Specifically, the study investigated (1) the effect the PReP has on learning when used with predominantly Anglo and Hispanic high school students in conjunction with a social studies textbook reading assignment; (2) whether…
