The second edition of the International Test Commission Guidelines for Translating and Adapting Tests was prepared between 2005 and 2015 to improve upon the first edition, and to respond to advances in testing technology and practices. The 18 guidelines are organized into six categories to facilitate their use: pre-condition (3), test development…

The patterns of cumulated structured volleyball practice and other structured sports activities of elite adult Brazilian players, considering age of specialization in volleyball and achievement of international competition representing the national team, were examined using Bayesian multilevel models. Elite volleyball players (n = 78) with an…

Most questionnaires construe avoidance as resulting from a problem-solving process and analyse only a few, single-factor and mostly non-adequate, forms of avoidance. The aim of the present study was to develop a multi-dimensional questionnaire to measure avoidance among adolescents. We tested the Avoidance Questionnaire for Adolescents (AQA) with…

Performance assessments, scenario-based tasks, and other groups of items carry a risk of violating the local item independence assumption made by unidimensional item response theory (IRT) models. Previous studies have identified negative impacts of ignoring such violations, most notably inflated reliability estimates. Still, the influence of this…

The purpose of this study was to develop a reliable and valid Likert scaled instrument to predict adult non-high school degree holders who would perform well academically in a project-based learning (PBL) assessment environment to obtain their high school diploma as opposed to traditional standardized tests such as the General Educational…

The high level of attrition and low rate of certification in Massive Open Online Courses (MOOCs) has prompted a great deal of research.

Heightened accountability pressures and an increased emphasis on teaching quality have directed scholarly attention to scrutinizing instruction, particularly with respect to issues of validity and reliability. However, these attempts have largely been directed toward "core" content areas and investigated generic or content-specific…

Network meta-analysis (NMA) combines direct and indirect evidence comparing more than 2 treatments. Inconsistency arises when these 2 information sources differ. Previous work focuses on inconsistency detection, but little has been done on how to proceed after identifying inconsistency. The key issue is whether inconsistency changes an NMA's…

This paper examines how exposure to counter-attitudinal messages from the party an individual identifies with…

The Education Value-Added Assessment System (EVAAS), the value-added model (VAM) sold by the business analytics software company SAS Institute Inc., is advertised as offering "precise, reliable and unbiased results that go far beyond what other simplistic [value-added] models found in the market today can provide." In this study, we…
