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.     

Judging Teachers: the social and political contexts of teacher evaluation

This paper argues that the assessment and evaluation of teachers in slate provided schooling in Britain has never been simply a matter of technical competence. Judging teachers has always involved social, ideological and political considerations which have varied in different historical periods.

An analysis is made of attempts to apply principles and procedures of assessment especially to teachers in urban working class schools. It is shown that these attempts have historically moved from a ‘visible’ strategy of direct imposition and surveillance to an ‘invisible’ strategy through the ethic of legitimated professionalism. Current developments in British schooling suggest, however, a possible return to more direct and visible procedures as ‘teacher incompetence’ is placed at the centre of the education problem.     

Nineteenth-Century Telegraphy: Wiring the Emerging Urban Corporate Economy

Nineteenth-century telegraphy had a vital integrative role in the intersecting and mutually constituted developments of American industrialization, urbanization, and mediatization. Previous work by Tarr, Finholt, and Goodman¹1. Tarr, Finholt, and Goodman, The City and the Telegraph.View all notes focused on the internal activities of business, fire, and police institutions in American cities. Here, I move beyond their approach in relating telegraphy to broader infrastructural developments of national-level urban industry and modern mass media in the late nineteenth century and the rise of dominant, networked urban commercial, industrial, financial, and media centers. By radically accelerating the mobility of information and capital, telegraphy significantly reduced barriers of distance to industry, commerce, news and advertising, and state and military interventions. Owing to its commercial ownership in the USA, telegraphy privileged business over public use in comparison to Western Europe. Its enduring effects were its integrative functions in the development of a large-scale, urban-centered, largely private system of mass production, mass media, mass culture, and mass consumption.     

Managing Bibliographic Data Quality in a Consortial Academic Library: A Case Study

This article presents a case study of quality management for print and electronic resource metadata, summarizing problems and solutions encountered by the Cataloging and Discovery Services Department in the George A. Smathers Libraries at the University of Florida. The authors discuss national, state, and local standards for cataloging, automated and manual record enhancements for data, user feedback, and statewide consortial factors. Findings show that adherence to standards, proactive cleanup of data via manual processes and automated tools, collaboration with vendors and stakeholders, and continual assessment of workflows are key to the management of biblio-graphic data quality in consortial academic libraries.

The Effect of Team‐Based Learning on Student Attitudes and Satisfaction

We examined student attitudes toward a team‐based learning method known as the readiness assurance process encompassing team exams to model how student satisfaction is initially shaped and subsequently changed over time as a function of scholastic performance and perceived development of professional skills (PS). We found that students were generally positively disposed toward the learning method and recognized its benefits in terms of developing teamwork skills. A regression analysis of student responses to an instrument distributed directly after each of four quizzes given over the course of a semester leads to the inferences that satisfaction with the method depends minimally upon the immediate feedback provided by student performance on a quiz and more critically upon student perceptions of how it has enhanced their PS. There is also shown to be a strong carryover effect in satisfaction with the method in successive uses. The results suggest that student attitudes are shaped by multiple, high‐level goals, and not just scholastic performance. The study also evidences the need to study learning interventions over multiple uses rather than through a one‐shot design.
