This report looks at why men are more likely than women to achieve first-class degrees at Oxford and Cambridge. This situation stands in stark contrast to the UK higher education sector as a whole, where women are generally more likely to achieve both first-class honours and 'good' honours. The author argues that the first-class awarding gap…

The five thoughtful papers included in this issue of "Educational Researcher" ("ER") raise new questions about the use of value-added methods (VAMs) to estimate teachers' contributions to students' learning as part of personnel evaluation. The papers address both technical and implementation concerns, considering potential…

The Council for the Accreditation of Educator Preparation (CAEP) requires faculty from educator preparation programs to provide evidence of credential candidates' impact on K-12 student learning. However, there is a paucity of information on preparation programs' use of direct assessments of student learning to gauge credential candidate…

This paper presents myths as well as facts about value-added analysis. These myths include: (1) "Value-added isn't fair to teachers who work in high-need schools, where students tend to lag far behind academically"; (2) "Value-added scores are too volatile from year-to-year to be trusted"; (3) "There's no research behind value-added"; (4) "Using…

This paper is meant to highlight the occurrence of Simpson's Paradox when using aggregated data obtained from two IEA studies in Israel, while ignoring the effect of a powerful intervening variable in the local context--the ethnicity factor. It will demonstrate faulty conclusions regarding either the absence of relationships between a contextual…

This brief considers the problem of using value-added scores to compare teachers who work in different schools. The author focuses on whether such comparisons can be regarded as fair, or, in statistical language, "unbiased." An unbiased measure does not systematically favor teachers because of the backgrounds of the students they are…

Since their inception, charter schools have been a lighting rod for controversy, with much of the debate revolving around their effectiveness in improving student achievement. Previous research has shown mixed results for student achievement; this could be the consequence of different policy environments or varying methodological approaches with…

Much grading of student work is based, overtly or tacitly, on assumptions derived from scientific measurement. However, the practice of grading and the cumulation of grades into an overall index of achievement are socially constructed activities that fall a long way short of what is expected of scientific measurement. If scientific measurement is…

In this paper, we argue that, as indicators of the educational quality of graduate degree programs, student theses and dissertations are best used in specific contexts. High-quality theses and dissertations, that is, may be the result of factors such as verbal skills students already possessed at admission or of complex interactions between…

There are many ways to use student test scores to evaluate schools. This paper defines and examines different estimators, including regression-based value-added indicators, average gains, and successive cohort differences in achievement levels. Given that regression-based indicators are theoretically preferred but not always feasible, we consider…

Effective principals are those who boost academic achievement for all students, increase the effectiveness of their teaching staffs, and consistently take leadership actions shown to improve outcomes for students. Therefore principal evaluation systems should place 70% of their weight on the ability of principals to increase student achievement…

Value-added measures can be used to allocate funding to schools, to identify those institutions in need of special attention and to underpin government guidance on targets. In England, there has been a tendency to include in these measures an ever-greater number of contextualising variables and to develop ever-more complex models that encourage…

The formula is simple: Highly effective teachers equal student academic success. Yet, the physics of American education is anything but. Thus, the question facing education reformers is how can teacher effectiveness be accurately measured in order to improve the teacher workforce? Given the demand for objective, quantitative measures of teacher…

Semester assessment of college wind band members is an issue that conductors would probably agree falls within their academic freedom. Institutions may award as little as no credit or even a percentage of a credit for ensemble participation, although the time and effort required of the students and their conductor is undoubtedly equivalent to, or…

In large-scale assessments, such as state-wide testing programs, national sample-based assessments, and international comparative studies, there are many steps involved in the measurement and reporting of student achievement. There are always sources of inaccuracies in each of the steps. It is of interest to identify the source and magnitude of…
