Local education agencies (LEAs) continue to use value-added models (VAMs) for teacher evaluation policies and purposes, often with consequences attached. Although the Every Student Succeeds Act (ESSA) provides more flexibility to LEAs, few have discontinued VAM use, suggesting they interpret VAMs as a valid measure of teacher effectiveness. In…

The number of years to estimate value-added measures (VAM) has received insufficient attention. Researchers often use as many years as available, to increase precision and decrease transitory sorting bias. However, this decision has little theoretical or empirical backing. We develop a theoretical framework and evaluate data from thousands of…

A relevant learning space for academics, especially junior researchers, is the academic conference. While conference participation has long been associated with personal attendance at the conference venue, virtual participation is becoming increasingly important. This study investigates the perceived value of a purely virtual academic conference…

This paper aims to identify and compare key factors influencing US States' or an OECD country's decision to employ student test scores or test score value-added (VAM) in evaluating teacher effectiveness. Analysis using multiple linear probability model and logistic regression frameworks indicates that the use of VAM/student test scores was…

In this article, we explore whether the evaluation instruments used in the teacher selection process in Peru are good predictors of teacher effectiveness. To this end, we estimate teacher value-added (TVA) measures for public primary school teachers and test their relationship with Peru's results of two rounds of the teacher evaluation (i.e., a…

Literature has examined teacher leadership (TL) roles, definitions, applications in schools, and, most recently, its presence in high-performing public schools, like the US National Blue Ribbon Schools (NBRS). This study featured principal and teacher leader interviews (n = 20) from NBRS recognized during the pandemic (2020 and 2021), alongside…

Ongoing or recently completed across the United States are a series of lawsuits via which teacher plaintiffs are contesting how they are being evaluated using value-added models (VAMs) as part of states'/districts' teacher accountability systems. To investigate the empirical and pragmatic matters addressed in court, researchers conducted a case…

In the context of Bayesian factor analysis, it is possible to compute plausible values, which might be used as covariates or predictors or to provide individual scores for the Bayesian latent variables. Previous simulation studies ascertained the validity of mean plausible values by the mean squared difference of the mean plausible values and the…

We assessed whether an adaptation of value-added analysis (VAA) can provide evidence on the relative effectiveness of interventions implemented in a large school district. We analyzed two datasets, one documenting interventions received by underperforming students, and one documenting interventions received by students in schools benefiting from…

A growing literature uses value-added (VA) models to quantify principals' contributions to improving student outcomes. Principal VA is typically estimated using a connected networks model that includes both principal and school fixed effects (FE) to isolate principal effectiveness from fixed school factors that principals cannot control. While…

This study focused on the performance of students from traditional and nontraditional high schools in Jamaica and the value-added to student outcomes. The student considers issues of excellence and equity as it relates to the student's performance. An extant database was used with student examination results for the Grade Six Achievement Test…

This article describes the inclusion of a novel online student-centered resource--a Virtual Executive in Residence (VER)--who was embedded within four graduate online asynchronous courses across three semesters. Pre- and post-qualitative student perceptions from two consecutive semesters (across 48 students) were initially used to explain the…

This paper investigates the differential effectiveness of teachers across student populations, with a focus on gifted and talented (GT) students. Using data from Los Angeles, we estimate teacher effectiveness (proxied by value-added measures (VAMs) of teachers' contributions to student achievement growth) for GT students and examine how they are…

The current study sought to characterize three partnership models in Israeli academic institutions--the traditional, the academia-classroom, and the clinical field-focused models. 42 interviews were conducted with educators (teacher educators; mentor teachers; program heads) at 14 Israeli colleges and universities where the programs take place.…
