STATGRAPHICS, a statistical package written for the IBM PC/XT/AT, is reviewed. In addition to superb graphics, STATGRAPHICS is unequalled in time series procedures, quality control, linear programming, and other mathematical procedures. The modules for regression analysis, categorical data analysis, and nonparametric analysis are good, but contain…

Over the past 15 years a body of research has investigated organizational transitions in adolescent development. Researchers studying school transitions exclusively ask whether significant transition affects students' social and psychological development.

Illustrates problems facing researchers trying to demonstrate causal relationships between types of nonparental care and differences between groups of Swedish children. Argues that efforts must be made to validate and interpret differences that are found. Indicates ways to avoid misinterpretation of differences that are attributable to…

Purpose: To evaluate the efficacy of a 6-month course of responsivity education/prelinguistic milieu teaching (RE/PMT) for children with developmental delay and RE/PMT's effects on parenting stress in a randomized clinical trial. Method: Fifty-one children, age 24-33 months, with no more than 10 expressive words or signs, were randomly assigned to…

Multivariate statistical analysis determined relationships between scores on the Otis-Lennon School Ability Test and the Stanford Achievement Test at grades 2, 4, and 6 for 272 students. The best predictor of achievement at a later grade was achievement at an earlier grade. Implications are discussed. (SLD)

One of the motivations frequently cited by Sen and Nussbaum for moving away from a utility metric towards a capabilities framework is a concern about adaptive preferences or conditioned expectations. If utility is related to the satisfaction of aspirations or expectations, and if these are affected by the individual's previous experience of…

Although methodological integrity is not the sole determinant of the value of a program evaluation, decision-makers do have a right, at a minimum, to be able to expect competent work from evaluators. This paper explores five areas where evaluators might improve methodological practices. First, evaluation reports should reflect the limited…

A framework for understanding methodological practices from the perspectives of internal validity, external validity, statistical control validity, and construct validity is presented. One hundred doctoral dissertations completed between 1980 and 1988 at a single urban public university were analyzed for various methodological practices and types…

This study attempted to examine selected features of principal-teacher behavior in relation to the educational environment of elementary schools. Subtests of Halpin's Organizational Climate Description Questionnaire were used to obtain teacher perceptions of the principal variables of Aloofness, Production, Emphasis, Thrust, and Consideration; and…

International Lending Institutions (ILIs) and Non-Governmental Organisations (NGOs) continuously design and implement Educational System Typologies (ESTs) in order to evaluate a nation's educational performance in terms of quality of life improvements; Traditional ESTs are therefore constantly put at odds by the advent of new ESTs. This study aims…

Rectifies the unsatisfactory textbook treatment of the finite-sample proprieties of estimators of regression models with a lagged dependent variable and autocorrelated disturbances. Maintains that the bias of the ordinary least squares estimator is determined by the dynamic and correlation effects. (MJP)

The aim of this study is to analyse the possible effects of Age of Onset (AO), Cognitive Maturity (Age at Testing--AT) and Amount of Exposure (AE) on the productive vocabularies of learners of English as a Foreign Language (FL). Three groups of bilingual Catalan/Spanish students were tested towards the end of Secondary Education. The groups…

A broad spectrum of methodologies pertinent to studies of schooling effects are reviewed. Methodological issues and problems are addressed according to a three-dimensional conceptual framework: (1) indicators of schooling effects; (2) study approaches; and (3) units of analysis. Problems and uses of status attainment and difference scores as…
