In this study, I explore the experiences of five Japanese returnees ("kikokushijo"). The participants recorded taped monologues or wrote narratives reflecting on their time spent living abroad and of returning to Japan. These retrospective life stories revealed four prominent themes of conflict: group orientation; bullying and…

The focus of the study was on empirically providing a composite picture of the relationship of some representatives of school, student and teacher factors on students' environmental conservation habit of a school-based Environmental Education programme. The study sample comprised 584 members of the Nigerian Conservation Foundation (NCF) School…

Concerns about the importance of variation in statistics education and a lack of research in this topic led to a preliminary study which explored pre-service teachers' ideas in this area. The teachers completed a written questionnaire about variation in sampling and distribution contexts. Responses were categorised in relation to a framework that…

Using meta-analysis, randomized experiments in education that either clearly did or clearly did not experience student attrition were examined for the baseline comparability of groups. Results from 35 studies suggested that after attrition, the observed measures of baseline comparability of groups did not differ more than would be expected given…

The use of stepwise methodologies has been sharply criticized by several researchers, yet their popularity, especially in educational and psychological research, continues unabated. Stepwise methods have been considered particularly well suited for use in regression and discriminant analyses, but their use in discriminant analysis (predictive…

When the same parameters are estimated by data from several independent samples, it may happen that, for any pair of samples, even though the test for parameter discrepancy is statistically significant, the two individual confidence intervals overlap. To overcome this potential contradiction, a new type of one-sample confidence intervals is…

Rigorous comparison of the reliability coefficients of several tests or measurement procedures requires a sampling theory for the coefficients. This paper summarizes the important aspects of the sampling theory for Cronbach's (1951) coefficient alpha--a widely used internal consistency coefficient. This theory enables researchers to test a…

The NFER has devised a set of English proficiency tests suitable for immigrant junior-school children. What do these tests reveal about the levels of linguistic skill found in different immigrant groups? (Editor)

Use of Tukey's Jackknife in establishing a confidence interval around the population coefficient alpha is explored and the robustness of Feldt's procedure along with ten variants of the Jackknife when the data do not conform to the necessary normality requirements are evaluated. Only two of the variants compared to Feldt's approach. (RC)

The paper points out that, in working with special groups, correlations are often distorted because the variability of the measures being correlated are restricted in the groups. Presented is a formula whereby a Pearson product-moment correlation can be corrected for restrictions in range in situations where the basis of selection is unmeasured,…
