Different conceptualizations exist about the components of the knowledge teachers need to teach mathematics with professional consciousness, and a researcher needs to describe and assess that knowledge. The fact, however, is that different conceptualizations respond to different needs, and thus, the variety is even a chance to develop the field…

Student surveys have gained prominence in recent years as a way to give students a voice in their learning process, and teacher self-reports have always been an effective instrument for revealing the planning, intentions, and expectations behind a given lesson. Though student and teacher surveys are widely used, extant research in education has…

Two quantitative measures of school performance are currently used, the average points score (APS) at Key Stage 2 and value-added (VA), which measures the rate of academic improvement between Key Stage 1 and 2. These figures are used by parents and the Office for Standards in Education to make judgements and comparisons. However, simple…

States, districts, and schools all across the United States are busy developing or implementing teacher evaluation systems. One can trace this flurry of activity to a variety of reports and initiatives that highlight two failings of past efforts: (1) Teacher evaluation systems have not accurately measured teacher quality because they've failed to…

The literature on effective schools emphasizes teacher quality as a critical input for improving student outcomes. Teacher certification status, years of experience and possession of a graduate degree are three factors commonly taken into consideration when assessing teacher quality. With the advent of advanced measurement tools, however,…

Student Evaluations of Teaching (SETs) play a central role in modern academia. They are used for tenure, promotion, teaching improvement and other important decisions. One would think that the data collected from a SET would be analysed correctly, but such is typically not the case, as can be seen in this study later. Therefore we propose a…

The author reports on the debate about "value added" measures of teaching which may be the most divisive topic in teacher-quality policy today. It has generated sharp-tongued exchanges in public forums, in news stories, and on editorial pages. And it has produced enough policy briefs to fell whole forests. But for most of the nation's teachers,…

Using computers to evaluate teachers based on student test scores is more difficult than it seems. Value-added modeling is a genuinely serious attempt to grapple with the difficulties. Value-added modeling carries the promise of measuring teacher quality automatically and objectively, and improving school systems at minimal cost. The essence of…

Purpose: This paper proposes a benefit of the doubt (BoD) approach to construct and analyse teacher effectiveness scores (i.e. SET scores). Design/methodology/approach: The BoD approach is related to data envelopment analysis (DEA), a linear programming tool for evaluating the relative efficiency performance of a set of similar units (e.g. firms,…

This report presents the value-added models that will be used to measure school and teacher effectiveness in the District of Columbia Public Schools (DCPS) in the 2010-2011 school year. It updates the earlier technical report, "Measuring Value Added for IMPACT and TEAM in DC Public Schools." The earlier report described the methods used…

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…

The District of Columbia Public Schools (DCPS) has incorporated measures of school and teacher effectiveness, based on student test score growth, into a new teacher assessment system known as IMPACT. Implemented for the first time during the 2009-2010 school year, IMPACT is an assessment system with significant consequences. Prior to the start of…

This report describes the value-added models used as part of teacher evaluation systems in the District of Columbia Public Schools (DCPS) and in eligible DC charter schools participating in "Race to the Top." The authors estimated: (1) teacher effectiveness in DCPS and eligible DC charter schools during the 2011-2012 school year; and (2)…

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…

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…
