The Raven's Standard Progressive Matrices (RSPM) is a 60-item test for measuring abstract reasoning, considered a nonverbal estimate of fluid intelligence, and often included in clinical assessment batteries and research on patients with cognitive deficits. The goal was to develop and apply a predictive model approach to reduce the number of items…

A latent variable modeling method is outlined, which accomplishes estimation of criterion validity and reliability for a multicomponent measuring instrument with hierarchical structure. The approach provides point and interval estimates for the scale criterion validity and reliability coefficients, and can also be used for testing composite or…

The purpose of the study was to determine if currently used FITNESSGRAM[R] cut-off scores for the Back Saver Sit and Reach Test had the best criterion-referenced validity evidence for 6-12 year old children. Secondary analyses of an existing data set focused on the passive straight leg raise and Back Saver Sit and Reach Test flexibility scores of…

The Halpern Critical Thinking Assessment (HCTA) is a reliable measure of critical thinking that has been validated with numerous qualitatively different samples and measures of academic success (Halpern, 2010a). This paper presents several cross-national applications of the assessment, and recent work to expand the validation of the HCTA with…

The Subjective Happiness Scale (SHS) constitutes an instrument for assessing subjective happiness. This study aims to present the validation of the SHS in a Portuguese adult population. A large representative sample (1,017 participants), from five different age groups was considered. Configurational invariance of the unidimensional structure of…

This article provides a detailed discussion of the theory and practice of modern regression discontinuity (RD) analysis for estimating the effects of interventions or treatments. Part 1 briefly chronicles the history of RD analysis and summarizes its past applications. Part 2 explains how in theory an RD analysis can identify an average effect of…

The use of computer algebra systems such as Maple and Mathematica is becoming increasingly important and widespread in mathematics learning, teaching and research. In this article, we present computerized proof techniques of Gosper, Wilf-Zeilberger and Zeilberger that can be used for enhancing the teaching and learning of topics in discrete…

Purpose: To determine the concurrent validity of the Conditioned Assessment of Speech Production (CASP; Ertmer & Stoel-Gammon, 2008) and data obtained from speech samples recorded at the same intervals. Method: Nineteen children who are deaf who received cochlear implants before their 3rd birthdays participated in the study. Speech samples and…

[Slides] presented at the annual conference of the Southern Association for College Admission Counseling, April 2010. This presentation summarizes recent research from the national SAT Validity Study and includes information on the Admitted Class Evaluation Service (ACES) system and how ACES can help institutions conduct their own validity…

Background: Large-scale survey assessments have been used for decades to monitor what students know and can do. Such assessments aim at providing group-level scores for various populations, with little or no consequence to individual students for their test performance. Students' test-taking behaviors in survey assessments, particularly the level…

This article synthesizes reading intervention research studies intended for use with struggling or at-risk students to determine which studies adequately address population validity, particularly in regard to the diverse reading needs of English language learners. An extensive search of the professional literature between 2001 and 2010 yielded a…

The purpose of the present study is to develop a valid and reliable map literacy scale that is able to determine map literacy of individuals, especially that of high school and university students. The study sample was composed of 518 students studying at various faculties at Cumhuriyet University and high schools in Sivas and its counties. With…

Given the serious consequences of making ill-fated admissions and funding decisions for applicants to graduate and professional school, it is important to rely on sound evidence to optimize such judgments. Previous meta-analytic research has demonstrated the generalizable validity of the "GRE"® General Test for predicting academic…

In recent years, the social sciences have seen a resurgence in the study of divergent thinking (DT) measures. However, many of these recent advances have focused on abstract, decontextualized DT tasks (e.g., list as many things as you can think of that have wheels). This study provides a new perspective by exploring the reliability and validity…

Students in a senior English class examined the question of whether the "wisdom of experts" or "the wisdom of crowds" is more reliable and useful in a writing course by engaging in a parallel Wikipedia project. Each student either created a new entry or made significant changes to an existing Wikipedia entry, tracked changes to…
