This meta-analysis examined the influence of attributes related to the implementation of learning strategy instruction interventions on students' academic performance, and also examined how the attributes related to the method of testing the intervention effects affected the actual effects measured. Using metaregression, we analyzed the…

The preservice and in-service predictors of 1,668 Part C early intervention and Part B(619) preschool special practitioners' perceived self-efficacy beliefs are reported. The preservice variables were type of degree (discipline), years of formal postsecondary education, licensure, and participants' judgment of how well their preservice training…

The purpose of this analysis was to examine academic intentions, parental support, and peer support as predictors of self-reported academic behaviors among a sample of 329 first- and continuing-generation college freshmen. Regression analyses revealed that different variables predicted academic behaviors for the three groups examined (students…

Compares approaches to modeling ordinal outcome variables, including assumptions, interpretations, and limitations. Explores how the multiple regression approach with ordinal level data can compromise the understanding of the effects of the independent variables and of the ordinal level response. Provides applications with data from a multisite…

The 2000 US presidential election between Al Gore and George W. Bush has been the most intriguing and controversial in American history. Using the Florida ballot data, Wu showed that the 2000 election result could have been reversed had the "butterfly ballot effect" been eliminated. Through a combinatorial approach, Harger concluded that…

This overview of both quantitative and qualitative methods of educational forecasting is introduced by a discussion of a general typology of forecasting methods. In each of the following sections, discussion follows the same general format: a number of basic approaches are identified (e.g. extrapolation, correlation, systems modelling), and each…

Contrasts aptitude by treatment interaction (ATI) and hierarchical linear modeling (HLM) methods for making cross-level inferences between individual-level and group-level factors in school effectiveness research. Recommends HLM when intraclass correlations are high. ATI is suitable when intraclass correlations are low, but partitioning the…

Discusses multiple regression, a very popular statistical technique in the field of education. One of the basic assumptions in regression analysis requires that independent variables in the equation should not be highly correlated. The problem of multicollinearity and some of the solutions to it are discussed. (Author)

The inclusion of unmeasured variables in path analyses in educational research is discussed. The statistical basis for inclusion is presented, along with several examples. (JKS)

A search for better predictors of incomes of high school and college graduates is described. The accuracy of the prediction, implicit in the work of John R. Walsh of Harvard University, that the income differences in a given year are good indicators of income differences in future years, was tested by applying standard statistical procedures to…

This present research reveals how beer advertising affects adolescents' knowledge of beer brands, drinking attitudes, and drinking behaviors. In addition to traditional psychological approaches for measuring media effects on alcohol-related behaviors and attitudes, market research advertising tracking methods were included to permit a clearer and…

Discussion of how we perceive meaning from graphics highlights a computer simulation model, UCIE (Understanding Cognitive Information Engineering), that simulates graphical perception. An empirical study is described that compared actual performance to UCIE predictions related to the amount of time required to answer a question in various…

Describes study of students in grades 8 through 12 that was conducted to determine the degree to which television messages influence a person's construction of reality (the cultivation hypothesis). Research methodology that tests the effects of television exposure is examined with emphasis on the importance of demographic control variables. (38…

Examined and compared the psychosocial predictors of a mother's decision to work and the number of hours worked in Argentina compared to the U.S. Results from 78 U.S. and 68 Argentinean women revealed that better educated, higher status U.S. women worked longer hours after childbirth than similar women in Argentina. Cultural and economic…

The changing achievement relationships among students, from elementary through high school, were investigated between their ages relative to their classmates and their ages at entry into first grade. A secondary analysis was performed on the data collected by the National Assessment of Educational Progress. The sample involved Caucasian students…
