Meta-analysis is a methodology that can be used to summarize the results of quantitative studies and allows a researcher to evaluate how the outcomes may vary systematically. (Author)

Job analyses were compared with employees' self-ratings of abilities across 54 occupations. Participants totaled 2,272 workers (1,119 women and 1,153 men) who took the Career Decision-Making System as part of an effort to expand its concurrent validity evidence. The results supported the validity of self-assessment of aptitudes in career…

Notes that presence of heterogeneous regression slopes in an analysis of covariance design is equivalent to presence of interaction in randomized-blocks design. Describes modification of the usual graphical representation of heterogeneous regressions that can aid in interpreting significant regions for regression surfaces. (NB)

Discusses two approaches to data analysis in pretest-posttest research designs in which researcher has not formed groups based on pretest or used pretest information in assigning participants to groups, thus ruling out two-way analysis of variance. Describes use of repeated-measures analysis of variance and two-group analysis of covariance in…

Presents first of two-part editorial (second part to appear in next journal issue) proposing guidelines for developing useful tables to report multiple regression outcomes. Pays particular attention to situations where a hierarchical multiple regression analysis is guided by theory. Concludes that some conventional way to report multiple…

Discusses problems researchers face when they want to describe relationship between several predictors and criterion variable. Considers ways of addressing problem of contribution of each predictor depending on which other predictors are in regression equation. Focuses on parallel information for each variable, examining initial and final…

Considers objections to comparisonwise position, which holds that, when conducting simultaneous significance procedures, per-test Type I error rate should be controlled and that it is unnecessary to introduce adjustments designed to control familywise rate. Objections collected by Saville in an attempt to refute them are discussed along with…

Discusses simultaneous inference, term for techniques that have been designed to limit the probability of one or more false rejections of null hypotheses (Type I errors) for a set of significance tests. Presents and reviews some of the better-known simultaneous inference techniques. (NB)

Introduces special journal issue on policy-driven assessment in elementary and secondary schools by highlighting themes in the 13 articles in the issue and by posing questions related to new policies and testing practices that are being implemented in the schools. Also presents conjectures about state and national testing programs. (NB)

Contends that skills teachers need to be effective partners in development of better assessment practice are related to teachers' levels of classroom assessment training. Examines need for teacher competence in assessment, changing kindergarten through grade 12 assessment scene, teachers' roles in new assessments, teachers' training in assessment,…
