Some Reservations About the Use of the Analysis of Co‐variance in Educational Research: a response to Dugard and Todman

Dugard and Todman (this issue), in this journal, present convincing arguments for the greater utilisation by educational researchers of the analysis of co‐variance when analysing data from experiments employing pre‐test‐post‐test control group designs. We applaud this initiative, but caution against too readily employing co‐variance procedures where it may be inappropriate to do so and repeat some of the cautions concerning ‘pitfalls for the unwary’ previously voiced (Lambourne & Wheldall, 1979).     

From State Control to Governance: Decentralization and Higher Education in Guangdong,China

In China there has been a strong trend to diversification and decentralization of education in the post-Mao period. This paper examines how the policy of decentralization has affected the governance of universities in Guangdong. More specifically, the paper focuses on reform of the financing and management structure, the merging of universities, and joint development programmes to enhance competitiveness. Despite these changes, the state's role as a regulator and overall service coordinator has been strengthened rather than weakened under the policy of decentralization. This paper not only examines the recent developments in Guangdong's higher education but also analyses such developments in light of the global trend towards decentralization in educational governance.     

Exploring the Robustness of a Unidimensional Item Response Theory Model With Empirically Multidimensional Data

Unidimensionality and local independence are two common assumptions of item response theory. The former implies that all items measure a common latent trait, while the latter implies that responses are independent, conditional on respondents’ location on the latent trait. Yet, few tests are truly unidimensional. Unmodeled dimensions may result in test items displaying dependencies, which can lead to misestimated parameters and inflated reliability estimates. In this article, we investigate the dimensionality of interim mathematics tests and evaluate the extent to which modeling minor dimensions in the data change model parameter estimates. We found evidence of minor dimensions, but parameter estimates across models were similar. Our results indicate that minor dimensions outside the primary trait have negligible consequences on parameter estimates. This finding was observed despite the ratio of multidimensional to unidimensional items being above previously recommended thresholds.     

From ‘brain drain’ to ‘brain bridging’: transnational higher education development and graduate employment in China

ABSTRACT

In the past few decades, the internationalisation of higher education has become an increasingly popular trend across different parts of the globe. The fierce global competition and the aggravating unemployment rate, coupled with low teaching and research quality revealed by universities in mainland China, have inevitably compelled a growing number of Chinese students, in particular the financially-able ones, to pursue higher education overseas or to enrol in transnational higher education offered in mainland China. Realising the severe problem of ‘brain drain’ and having a strong conviction to transform its higher education system to become more international for enhancing the global competitiveness of its higher education system, the Chinese government has made different attempts to enhance higher education quality by learning and incorporating new ideas and practices from overseas institutions, particularly encouraging the development of transnational higher education to change the higher education landscape. With particular reference to examining the way these students evaluate their future prospects in choosing different alternatives for further studies in higher education, this study sets out against the context briefly outlined above to critically analyse the motivation of students who choose to study abroad or enrol in Sino-foreign cooperation universities. This study also discusses the extent to which the internationalisation of higher education would affect the situations of ‘brain drain’ and graduate employment in China.     

MplusAutomation: An R Package for Facilitating Large-Scale Latent Variable Analyses in Mplus

MplusAutomation is a package for R that facilitates complex latent variable analyses in Mplus involving comparisons among many models and parameters. More specifically, MplusAutomation provides tools to accomplish 3 objectives: to create and manage Mplus syntax for groups of related models; to automate the estimation of many models; and to extract, aggregate, and compare fit statistics, parameter estimates, and ancillary model outputs. We provide an introduction to the package using applied examples including a large-scale simulation study. By reducing the effort required for large-scale studies, a broad goal of MplusAutomation is to support methodological developments in structural equation modeling using Mplus.     

Social Pragmatics: Preschoolers Rely on Commonsense Psychology to Resolve Referential Underspecification

Four experiments show that 4- and 5-year-olds (total N = 112) can identify the referent of underdetermined utterances through their Naïve Utility Calculus—an intuitive theory of people’s behavior structured around an assumption that agents maximize utilities. In Experiments 1–2, a puppet asked for help without specifying to whom she was talking (“Can you help me?”). In Experiments 3–4, a puppet asked the child to pass an object without specifying what she wanted (“Can you pass me that one?”). Children’s responses suggest that they considered cost trade-offs between the members in the interaction. These findings add to a body of work showing that reference resolution is informed by commonsense psychology from early in childhood.
