A content analysis of research published in the Journal of Research in Science Teaching from 1985 through 1989

To determine if actual practice was consistent with commonly recommended research methods and procedures, this study examined 130 studies reported over a 5-year period in three volumes of the Journal of Research in Science Teaching (JRST). The results were consistent with similar previous analyses (Shaver & Norton, 1980a, 1980b; Wallen & Fraenkel, 1988a) and indicate that appropriate generalizations beyond the confines of the reported studies may be impossible for most (64%) of the JRST studies surveyed. The findings also show that replication studies, which could be employed to offset deficiencies in generalizability, were not commonly encountered (3%) in these 130 reports. In addition, the study results indicate that many researchers (48%) do not properly restrict their conclusions based on the limits imposed by the accessible populations and samples used; nor do they typically provide possible alternative explanations for the outcomes obtained (76%). These findings prompt the following recommendations: 1. A greater awareness and use of replication as a check on generalizability should be encouraged by the science education community. 2. Clearly defined populations (target and accessible) and fully described samples warrant increased attention as report components from authors, reviewers, and editorial board members of JRST. 3. In light of the difficulties inherent in effecting random selection in educational settings, a greater emphasis should be placed on recognizing the limits that the underlying assumptions of inferential statistics place on research conclusions. The results of this study indicate that the methodological quality of published science education research should remain a concern for both practitioners and readers.     

Nonlongitudinal Estimation of Growth Curve Parameters: The Cohort Growth Model

The cohort growth model (CGM) is a method for estimating the parameters of a latent growth model (LGM) based on cross-sectional data. The CGM models the interindividual differences in the growth rate, and it models how subjects’ growth rate is related to their initial status. We derive model identification for the CGM and illustrate, in a simulation study, that the CGM provides unbiased parameter estimates in most simulation conditions. Based on empirical data we compare the estimates of the CGM with the estimates of the LGM. The results were comparable for both models. Although the estimates of the (co)-variances were different, the estimates of both models led to similar conclusions on the developmental change. Finally, we discuss the advantages and limitations of the CGM, and we provide recommendations for its use in empirical research.

Rows versus Tables. II. The Effects of Two Classroom Seating Arrangements on Classroom Disruption Rate,On‐task Behaviour and Teacher Behaviour in Three Special School Classes

Summary Seating arrangements in which children sat in rows and around tables were compared experimentally in three classes in a special school for behaviourally troublesome children with moderate learning difficulties. Children were observed daily in four two week phases: seated around tables, then in rows, again around tables, and finally again in rows. Percentage on‐task behaviour was recorded along with rate of pupil disruption and rates of teacher approval and disapproval. In all three classes on‐task behaviour doubled from around 35% to 70% as the conditions changed from tables to rows. Moreover, rate of disruption was three times higher in tables conditions. Teacher behaviour was also affected; positive comments increasing during rows whilst negative comments decreased. It is argued that these studies support the results of previous studies regarding the importance of ecological variables, such as seating, on classroom behaviour.     

How Parents Feel About Their Child’s Teacher/School: Implications for Early Childhood Professionals

The purpose of this article is to describe the effects that parent perceptions of their relationships with teachers have on parent involvement. After providing a brief review of literature identifying the importance of parent–teacher relationship formation, the authors provide suggestions for early childhood educators that will help them establish and maintain productive relationships with the families that they serve.     

The place of language learning in a liberal education: implications for curriculum policy in Ireland

This article attempts to expand, and to add to, one important aspect of the rationale for including the study of languages as part of a liberal education. Following criticism of the profile of the vocational rationale for language learning in Irish curriculum policy, the article develops recent research on the work of L. V. Shcherba to defend the role of language learning as part of a liberal education. The principal argument advanced and illustrated is that language learning has the potential to increase intellectual resources and, secondarily, to enhance literacy. This it achieves by introducing learners to new worlds of thought through revealing different linguistic maps for representing the world and by making them are aware of the nature of language. The argument is supplemented by reference to research in neuroscience that shows that knowledge of languages contributes to cognitive empowerment.     

A Review of Get Out: On White Terror and the Black Body

This essay provides a review of Jordan Peele's film, Get Out. The author argues that Peele's Get Out illustrates the protracted terrorism that is whiteness and the concomitant objectification and utilization of the black body for white survival, accumulation, and pleasure. The film challenges those in education to consider how anti-blackness operates within schools and education policy. More specifically, those in education should challenge longstanding inequities that foreclose the presents and futures of black youth.
