Latent growth curves within developmental structural equation models

This report uses structural equation modeling to combine traditional ideas from repeated-measures ANOVA with some traditional ideas from longitudinal factor analysis. A longitudinal model that includes correlations, variances, and means is described as a latent growth curve model (LGM). When merged with repeated-measures data, this technique permits the estimation of parameters representing both individual and group dynamics. The statistical basis of this model allows hypothesis testing of various developmental ideas, including models of alternative dynamic functions and models of the sources of individual differences in these functions. Aspects of these latent growth models are illustrated with a set of longitudinal WISC data from young children and by using the LISREL V computer program.     

Inferring Longitudinal Relationships Between Variables: Model Selection Between the Latent Change Score and Autoregressive Cross-Lagged Factor Models

This research focuses on the problem of model selection between the latent change score (LCS) model and the autoregressive cross-lagged (ARCL) model when the goal is to infer the longitudinal relationship between variables. We conducted a large-scale simulation study to (a) investigate the conditions under which these models return statistically (and substantively) different results concerning the presence of bivariate longitudinal relationships, and (b) ascertain the relative performance of an array of model selection procedures when such different results arise. The simulation results show that the primary sources of differences in parameter estimates across models are model parameters related to the slope factor scores in the LCS model (specifically, the correlation between the intercept factor and the slope factor scores) as well as the size of the data (specifically, the number of time points and sample size). Among several model selection procedures, correct selection rates were higher when using model fit indexes (i.e., comparative fit index, root mean square error of approximation) than when using a likelihood ratio test or any of several information criteria (i.e., Akaike’s information criterion, Bayesian information criterion, consistent AIC, and sample-size-adjusted BIC).     

Effective School Improvement: English Case Studies

This article compares 2 programmes in their roles played in stimulating effective school improvement. These programmes are the Local Education Authority (LEA-school district) in Birmingham and the university-inspired project “The Improving the Quality of education for All” (IQEA). The aims and characteristics of both programmes and the national accountability context within which these programmes function are described. Ten primary and secondary schools which are assisted by these programmes were visited during 1 day to compile a picture of each school's improvement journey and the key influences and constraints upon its progress. Emerging factors that appear to promote and discourage the capacity to change are described.     

An Examination of Lending Fees at 30 Academic Libraries in the Southeast

Current fiscal shortfalls are projected to bring deep and long-lasting budget cuts to libraries. With every budget dollar under close scrutiny, the urgency of filling patron information needs efficiently and cost-effectively increases. Interlibrary loan plays an important role in filling in gaps in library collections, yet as significant budget cuts are made at libraries of all sizes, materials will be available from fewer and fewer lenders. Libraries unable to find items from those with whom they have reciprocal arrangements will be will be forced to use lenders who charge. This article examines fees associated with interlibrary lending in 30 academic libraries in the southeast from 1995 and 2008.     

LEA support services for special educational needs provision and management

The National Foundation for Educational Research recently undertook research on the impact of delegation on local authority support services for special educational needs. This paper presents data on the provision offered by these services and the way in which they are managed. In particular, it examines how support is targeted, the extent and profile of service staff, mechanisms for the referral of pupils for support from the services, management structure, staff deployment and the professional development of service staff, and service monitoring, review and evaluation. Ways in which support services have developed in the 1990s, and their challenges for the next decade in the light of developments in the governance of education and the local policy context, are discussed.     

A SAS Interface for Bayesian Analysis With WinBUGS

Bayesian methods are becoming very popular despite some practical difficulties in implementation. To assist in the practical application of Bayesian methods, we show how to implement Bayesian analysis with WinBUGS as part of a standard set of SAS routines. This implementation procedure is first illustrated by fitting a multiple regression model and then a linear growth curve model. A third example is also provided to demonstrate how to iteratively run WinBUGS inside SAS for Monte Carlo simulation studies. The SAS codes used in this study are easily extended to accommodate many other models with only slight modification. This interface can be of practical benefit in many aspects of Bayesian methods because it allows the SAS users to benefit from the implementation of Bayesian estimation and it also allows the WinBUGS user to benefit from the data processing routines available in SAS.     

Online peer observation: its value in teacher professional development,support and well-being

This article discusses an online peer observation project conceived to enhance language-teacher positivity and creativity in synchronous virtual classrooms. Participants worked part-time at the UK’s Open University (OU) in a blended context and came from two different groups distant from each other and geographically dispersed within their own group. As a result of the project, participants perceived an increase in their confidence and greater willingness to experiment. They appreciated better how they fitted into the wider OU teaching community, built new professional friendships and flexible communities of practice, and developed a better understanding of how to progress their own self-development.     

The pastoral care of international students in New Zealand: is it more than a consumer protection regime?

Student security is a composite social practice that includes the domains of consumer rights, entitlement to a range of welfare supports and pastoral care, and freedom from exploitation and discrimination. Three traditions shape the systems used for managing and regulating international student security in the nations that export education: pastoral care, consumer protection and quasi-citizenship. Each has different implications for the positioning of students as agents. This study used semi-structured interviews with 70 international students from nine countries in two contrasting universities. It investigated the provision of international student security, including the distinctive New Zealand regime of security, regulated by the National Code of Practice for the Pastoral Care of International Students. This Code binds provider institutions and the International Education Appeal Authority, and permits Code-based claims by students from providers. The study found that international students in New Zealand have varying expectations of student security, which draws eclectically from all three traditions. There are gaps in the coverage of pastoral care, including the areas of financial matters and intercultural relations. Where the Code does provide protection, its provisions are not always fully implemented, such as for accommodation assistance. More seriously, there is little knowledge among students of the Code of Practice and their Code-based entitlements, and almost no knowledge of the Appeal Authority. Numerous students testified to poor information flow. This limits not only their capacities as quasi-consumers and their access to pastoral services – so that in practice, the New Zealand system is similar to the Australian system, which is explicitly limited to consumer protection – but even their ability to fully utilize consumer protection. This defect renders the promise of a regulated pastoral care regime grounded in active student agency largely inoperative.     

Out of school: a phenomenological exploration of extended non-attendance

The concept of “extended non-attendance” (“school phobia” or “school refusal”) was distinguished from truancy early in the twentieth century, and refers to children who fear school and avoid attending. Despite much subsequent research, outcomes for those affected remain poor, and their voices remain largely absent from the evidence base. The current study sought to address this by examining the experiences of four secondary-age children with extended attendance difficulties. Data consisted of semi-structured interviews conducted in participants’ homes, subsequently analysed using Interpretative Phenomenological Analysis. Although participants differed markedly in their perception of the causes of their non-attendance, their support experiences appear remarkably similar. Emergent themes include being disbelieved, experiencing fragmented support, and feeling blamed and punished. Implications for practitioners include the importance of ensuring early intervention, the need to consider the individual child, and the importance of making sure that local intervention practices are informed by the evidence base.
