This user guide has been developed for users of the Longitudinal Surveys of Australian Youth (LSAY). It consolidates existing technical documentation and other information into one document. The guide aims to address all aspects of the LSAY data including: how to access the data, data restrictions, variable naming conventions, the structure of the…

Examines issues, especially definitional issues, in the practical application of effective naturalistic instructional (NI) practices in the instruction of young children with disabilities and their families. Suggests guidelines for describing independent and dependent variables in the procedural and contextual features of research into NI. (DB)

This article suggests the following emergent and early literacy research priorities: new theoretical accounts of emergent and early literacy; incorporation of recently developed, innovative study designs; and considerations of the brain development in research design. Priorities are also listed for exploring predictor variables and for…

To support and promote secondary analyses, the International Association for the Evaluation of Educational Achievement (IEA) is making the SITES 2006 international database and accompanying User Guide available to researchers, analysts, and public users. The database comprises national contexts and school- and teacher-level data from 23 education…

The perfunctory use of factor scores in conjunction with regression analysis is inappropriate for many purposes. It is suggested that factoring methods are most suitable for independent variable sets when some consideration has been given to the nature of the domain, which is implied by the predictors. (Author/BW)

The high school dropout problem has been called a national crisis. Educators, researchers, and policymakers continue to work to identify effective dropout prevention approaches. One important element of such prevention efforts is the identification of students at highest risk for dropping out and then the targeting of resources to keep them in…

Virtually all parametric statistical procedures have been shown to be special cases of canonical correlation analysis, which is a useful research methodology particularly when augmented by the calculation of canonical structure, index, and invariance coefficients. A logic for conducting stepwise canonical correlation analysis based upon evaluation…

The uses and restrictions of commonality analysis are described. Commonality analysis has been increasingly used as a method to examine the relative importance of independent variables, through the partitioning of variance among the variables of the regression equation into unique and common components. The effects of all other independent…

A broad conceptual framework is presented as a tool to guide researchers toward identification and development of variables in policy implementation studies. Concepts for developing variables to measure the "amount" of implementation and variables to identify the aspects of policy that need to be incorporated in a study are discussed.…

Using data describing entry into preschool among children with special needs, this paper introduces the fundamental statistical quantities of event occurrence--hazard and survivor functions. The paper discusses construction of formal statistical models of event occurrence over time, predictors that can be included in hazard models, and importance…

Indicator checklists (questionnaires or checklists that contain selected predictive items from longer, comprehensive instruments) are used by states to monitor the conformance of human service providers with state requirements. This guide provides instructions for developing such a checklist as part of an instrument-based program monitoring…

Argues that assessment, outcomes measurement, and prediction of attrition are separate but highly interrelated phenomena, with none meaningfully understood without reference to the other two. Suggests that the assessment process be the initial exercise, followed by periodic outcomes measurement used in conjunction with the assessment data to…

Describes findings from a study of 20 school superintendents, their background characteristics, and the elements in organizational structures around them related to their success in becoming superintendents. The purpose was to determine predictors of access to superintendency, particularly access for women. Some data reveal that discriminatory…

This booklet addresses the difficulties of comparing and drawing meaning from dropout data prepared by different agencies, and examines the characteristics of students--and of schools--that place students at risk for leaving school prematurely. The booklet describes prevention programs and presents evidence on their effectiveness. It reviews…
