SPREAD: A Distributed Simulation Toolkit

This article describes “SPREAD”, a simulation toolkit, and its use in building “Virtual Robots”, a simulation of multiple mobile robot vehicles used in the teaching of computer science at university level. A novel aspect of the simulator is the use of PVM (Parallel Virtual Machine) to achieve high performance at low cost by using spare CPU cycles on large numbers of networked workstations.     

Application of the Levenshtein Distance Metric for the Construction of Longitudinal Data Files

The analysis of longitudinal data in education is becoming more prevalent given the nature of testing systems constructed for No Child Left Behind Act (NCLB). However, constructing the longitudinal data files remains a significant challenge. Students move into new schools, but in many cases the unique identifiers (ID) that should remain constant for each student change. As a result, different students frequently share the same ID, and merging records for an ID that is erroneously assigned to different students clearly becomes problematic. In small data sets, quality assurance of the merge can proceed through human reviews of the data to ensure all merged records are properly joined. However, in data sets with hundreds of thousands of cases, quality assurance via human review is impossible. While the record linkage literature has many applications in other disciplines, the educational measurement literature lacks details of formal protocols that can be used for quality assurance procedures for longitudinal data files. This article presents an empirical quality assurance procedure that may be used to verify the integrity of the merges performed for longitudinal analysis. We also discuss possible extensions that would permit merges to occur even when unique identifiers are not available.     

Two- and Three-Year Achievement Results From the Memphis Restructuring Initiative

The purpose of this study was to analyze student achievement data from the first 3 years of the Memphis Restructuring Initiative (MRI). The MRI represents one of the first efforts by an urban school district to move past traditional top-down versus bottom-up reform debates by providing systemic support for outside-in/inside-out implementation and local co-construction of externally-developed reform designs in schools. Analyses of academic achievement focus on a state-of-the-art measure of value added assessments. At the end of 3 years the reforming schools had produced generally positive gains relative to locally matched control schools. Those results varied somewhat by reform type and by level of poverty in the communities being served. Based on the research methods used and the results, implications for future research and practice in educational reform are discussed.     

THE 1998 DAVID WILLS LECTURE: INTEGRATING THE LEGACY OF DAVID WILLS IN AN ERA OF BEHAVIOUR SUPPORT PLANS,INCLUSION AND TARGET SETTNG

This paper examines the legacy of the pioneering work of David Wills for current thinking and practice in current educational context between the needs of vulnerable children as revealed by wills and the demands for managerial accountability imposed by government.     

Analyzing Practice for Improving Schools: The Study of Vignettes

This article suggests a method for analyzing patterns of school practice for improvement purposes. In particular it describes outcomes of a study that point to some promising possibilities, in terms of encouraging teachers to reflect on their practice, for the purpose of improvement. It argues that by discussing and analyzing vignettes, teachers can improve their practice, not only individually, but also as a team. In addition, this analysis can help schools to develop as organizations. At the end, this suggestion is supported with an example which illustrates the potential of using vignettes for improving schools, whilst, at the same time, demonstrating how the procedure might be used.     

Making Critical Connections Between Social Studies Teaching and Student Achievement Using NAEP Data Explorer

In this analysis of promising practice, we demonstrate how social studies methods instructors can incorporate data analysis of the 2010 United States History National Assessment of Educational Progress (NAEP–USH) to facilitate pedagogical aims, engage teacher candidates in critical discourse, and investigate the contexts of teaching and learning. The NAEP data explorer application is a valuable tool for examining social studies theory and practice in relation to student learning outcomes. Our assessment of teacher candidates' responses to the activity leads to the recommendation that NAEP data analysis and results encourage self-evaluation of instructional practices while simultaneously supporting critical interpretations of the NAEP exam.
