Background: Educational and developmental psychologists often examine how groups change over time. Two analytic procedures -- analysis of covariance (ANCOVA) and the gain score model -- each seem well suited for the simplest situation, with just two groups and two time points. They can produce different results, what is known as Lord's paradox.…

At least sixteen US states have taken steps toward holding teacher preparation programs (TPPs) accountable for teacher value-added to student test scores. Yet it is unclear whether teacher quality differences between TPPs are large enough to make an accountability system worthwhile. Several statistical practices can make differences between TPPs…

While states are no longer required to set up teacher evaluation systems based in significant part on student test scores, quite a few continue to use value-added (VAMs) or student growth percentile (SGP) models for that purpose. In this study, we analyzed three years of teacher data to illustrate the performance of teachers' median growth…

While much has been written about the effects of standardized testing on student achievement, less work has addressed how parents take up this information. Drawing on a survey of 286 parents in a diverse urban school district, this research illuminates three aspects of parental response to test score information: 1) how parents relate various…

This study disaggregates posttest, pretest, and value-added or difference scores in economics into four types of economic learning: positive, retained, negative, and zero. The types are derived from patterns of student responses to individual items on a multiple-choice test. The micro and macro data from the "Test of Understanding in College…

Educators struggle with "value-added" teacher evaluation models based on high-stakes student assessments. Despite validity and reliability threats, these models evaluate university-based teacher preparation programs (TPPs), and play a role in state and professional accreditation. This study reports a more rational value-added evaluation…

The Every Student Succeeds Act (ESSA) proposes changes in how states include the nation's growing population of English Learners (ELs) into the accountability system. The purpose of this paper is to identify key issues and questions that might be considered and explored by state decision makers in this area. Our primary audience is anyone in a…

Although states and school districts have begun to evaluate school principals, there is little evidence on the validity of principal evaluation measures. To fill this gap, we examined Pennsylvania's Framework for Leadership (FFL), a tool for measuring and evaluating principals' professional practices. Using data on more than 300 principals, we…

This study investigates school effects on primary school students' language and mathematics achievement trajectories in Chile, a context of particular interest given its large between-school variability in educational outcomes. The sample features an accelerated longitudinal design (3 time points, 4 cohorts) together spanning Grades 3 to 8…

This study examines learning gains of college students' performance in critical thinking, reading, writing, and mathematics as assessed by the ETS Proficiency Profile (EPP). In this study, students' college learning gain was estimated by calculating the score differences between their first and last test administrations. Results revealed that (a)…

Despite evidence that many schools and districts have considerable discretion when hiring teachers and the existence of an extensive literature on teacher quality, little is known about how best to hire teachers. This is, in part, because predicting teacher quality using readily-observable teacher characteristics has proven difficult and there is…

Instructional labs are widely seen as a unique, albeit expensive, way to teach scientific content. We measured the effectiveness of introductory lab courses at achieving this educational goal across nine different lab courses at three very different institutions. These institutions and courses encompassed a broad range of student populations and…

Evaluations of teacher preparation programs (TPPs) based in part on the performance of program completers have emerged as an education reform strategy in several states and have become central features of the Race to the Top (RTTT) grant competition. The objective of this policy review is to examine how the state of Tennessee measured and reported…

Teacher performance pay programs are theorized to improve student achievement by incentivizing teachers, but opponents counter that teachers are not motivated by money. We used regression discontinuity techniques and data on a census of the students, teachers, and schools in a large urban minority-majority school district to show receipt of a…

The purpose of this study was threefold: (a) to examine the academic progress of students in reading, who have a learning disability in reading, as they transfer from pull-out support services to inclusion services; and (b) to examine the academic progress of general education students in reading, as they transfer from a general education setting…
