This article provides a brief introduction to the set of four articles in the special issue. To provide a foundation for the issue, key terms are defined, a brief historical overview of validity is provided, and a description of several different validation approaches used in the issue are explained. Finally, the contribution of the articles to…

This paper describes the development and validation of a set of three assessment instruments that can be used to assess students' progress on the energy concept (ASPECt) from fourth through twelfth grade. Rasch analysis techniques were used throughout the development process to guide the construction of an item bank and the selection of items for…

Background: The objective of this study was to develop the School Health Score Card (SHSC) and validate its psychometric properties. Methods: The development of the SHSC questionnaire included 3 phases: item generation, construction of domains and items, and field testing with validation. To assess the instrument's reliability and validity, we…

Functional Behavior Assessment (FBA) and behavior interventions have been effective in the management of challenging behavior among children with developmental disabilities including autism spectrum disorders. Research suggests the need for valid measurement instruments for verifying, calibrating and scoring competence in FBA and behavior…

Accurate measurement of quality of life (QoL) is important for evaluation of autism services and trials of interventions. We undertook psychometric validation of the World Health Organisation measure--WHOQoL-BREF, examined construct validity of the WHO Disabilities module and developed nine additional autism-specific items (ASQoL) from extensive…

This paper presents a transformative modeling framework that guides the development of assessment to measure students' deep understanding in physical sciences. The framework emphasizes 3 types of connections that students need to make when learning physical sciences: (1) linking physical states, processes, and explanatory models, (2) integrating…

This study discusses the need, development, and validation of the Innovation Test Instrument (ITI). This article outlines how the researchers identified the content domain of the assessment and created test items. Then, it describes initial validation testing of the instrument. The findings suggest that the ITI is a good first step in creating an…

In this article, we describe and illustrate the process by which we developed and validated short, multiple-choice, reliable tests to assess undergraduate students' comprehension of three mathematical proofs. We discuss the purpose for each stage and how it benefited the design of our instruments. We also suggest ways in which this process could…

In this article, we present several modifications to the Test of Understanding Graphs in Kinematics. The most significant changes are (i) the addition and removal of items to achieve parallelism in the objectives (dimensions) of the test, thus allowing comparisons of students' performance that were not possible with the original version, and (ii)…
