Apprentice and trainee data are reported by the State and Territory Training Authorities to National Centre for Vocational Education Research (NCVER) on a quarterly basis, starting at the September quarter of 1994. The set of data submitted that quarter is referred to as Collection 1. The sets of data submitted in subsequent quarters are referred…

Shortly after we published "Addressing Flawed Research in Developmental Education" (2012) in the "Journal of Developmental Education," Thomas Bailey, Shanna Smith Jaggars, and Judith Scott- Clayton from the Community College Research Center (CCRC) wrote a response rebutting several of our claims. Though their response corrects…

Global economic transformations have never been as dramatic as in the twentieth century. Most countries have experienced radical changes in the standards of income per capita, technology, fertility, mortality, income inequality and the extent of democracy in the course of the past century. It is the goal of many disciplines--economics, history,…

This technical paper examines the issue of attrition bias in two cohorts of the Longitudinal Surveys of Australian Youth (LSAY), based on an analysis using data from 1995 to 2002. Data up to 2002 provided eight years of information on members of the Y95 cohort and five years of information on members of the Y98 cohort. This study suggests that…

The present review examines research on the effects of technology use on reading achievement in K-12 classrooms. Unlike previous reviews, this review applies consistent inclusion standards to focus on studies that met high methodological standards. In addition, methodological and substantive features of the studies are investigated to examine the…

The gold standard in making causal inference on program effects is a randomized trial. Most randomization designs in education randomize classrooms or schools rather than individual students. Such "clustered randomization" designs have one principal drawback: They tend to have limited statistical power or precision. This study aims to…

This paper acknowledges that research on school dropouts presents problems in the definitions and computation of dropout indices. It considers a variety of methods for computing dropout rates, using dropout rates which are real and which were available at the end of the 1986-1987 school year. Fall enrollment, average daily membership, and total…

This study of early childhood and the family in member countries of the Organisation for Economic Co-Operation and Development (OECD) employs two statistical approaches to the problem of providing an accurate picture of modern conditions of family life. A classical demographic approach to population studies is initially used, then is critiqued,…

In this paper, tables for the appropriate sample sizes are presented and discussed in the context that the determination of the effect size must precede the determination of the sample size. (Author/PN)

In educational effectiveness research, multilevel models are increasingly used because these models take the multilevel structure of the data into account. In this paper, the effect of ignoring one or more levels of variation in hierarchical linear regression is explored, using a model with four hierarchical levels (individual pupil, class group,…

As an extension of B. Thompson's 1998 invited address to the American Educational Research Association, this paper cites two additional common faux pas in research methodology and explores some research issues for the future. These two errors in methodology are the use of univariate analyses in the presence of multiple outcome variables (with the…

This document contains two papers related to the 1993-94 Schools and Staffing Survey (SASS). The first paper documents some of the problems that were encountered during student sample selection and the methods used to resolve those problems. It also provides some suggestions to alleviate some of the problems in future SASS studies. Significant…

In 1987 the U.S. Census Bureau created a universe of private elementary and secondary schools for the National Center for Education Statistics (NCES). This universe has been updated every 2 years through list frame updating and area frame updating. For the list frame updating, lists of private schools are obtained from various associations around…
