By design, randomized experiments (XPs) rule out bias from confounded selection of participants into conditions. Quasi-experiments (QEs) are often considered second-best because they do not share this benefit. However, when results from XPs are used to generalize causal impacts, the benefit from unconfounded selection into conditions may be offset…

A test battery with two different levels of adaptation is presented: a within-subtest level for the selection of the items in the subtests and a between-subtest level to move from one subtest to the next. The battery runs on a two-level model consisting of a regular response model for each of the subtests extended with a second level for the joint…

In recent years, there has been increasing awareness on the benefits of social-emotional competencies (SEC) on Israeli students. A self-report SEL measure tailored to the Israeli context, however, has yet to be developed. This research aims to validate the Social-Emotional Questionnaire for Grades 4-6 (SEQ [G4-6]), a new self-report questionnaire…

Early identification of at-risk students is a critical element of Response to Intervention (RTI) but there are few validated universal screeners for high school mathematics. This study evaluated the effectiveness of the screening system currently in use at one urban Texas public high school and compared its effectiveness to alternate screening…

The original SOCO Scale was reduced to 10 items by Thomas, Soutar, and Ryan (2001). The author conducted a pretest and a posttest in his Personal Selling class during the Fall 2009 semester. Significant differences by gender, student sales experience and family member in the sales field were identified. The author once again pretested the…

Psychometric practice does not always converge with the advances of psychometric theory. In order to investigate this gap, the authors focus on the 10 most used psychological tests in Europe, as identified by recent surveys. The article analyzes test manuals published in 6 different European countries for these 10 most used tests. A total of 32…

Letter series and number series tests of items based on identical rules were administered to 160 male and 160 female undergraduates to determine comparability by testing equality of means, variances, and validity coefficients. Results indicate that letter and number series tests are not equivalent. Number series tests are easier, probably because…

This study was undertaken to determine reliability and validity estimates for a newly developed preschool inventory of cognitive functioning which provides many advantages over traditionally utilized measures. A predominantly pictorial stimulus-psychomotor response set was the format for the test. The test consisted of a series of 61 items divided…

Twelve structural models of similarity were fitted to data from conventional and computer adaptive test (CAT) batteries measuring the same aptitude in a double cross-validation design. Three of the 12 models, including a multiplicative structure model, performed well, providing support for using CATs as replacements for conventional tests. (NSF)

This study reports the preliminary results of a research project that focuses on the development of an abbreviated measure of computer anxiety, the Computer Anxiety Scale (CAS)-Short Form (SF), designed for use with upper elementary and secondary school students. The subjects involved in the study included 1075 students in grades 4 through 12,…

Reappraises the validity and reliability of Vocabulary and Block Design (V-VD) as a short form of the Wechsler Adult Intelligence Scale (WAIS), the Wechsler Intelligence Scale for Children (WISC), and the Wechsler Preschool and Primary Scale of Intelligence (WPPI). Presents a table for converting the sum of scaled scores into an estimate of Full…

The Idaho Comprehensive Literacy Assessment (ICLA) is a faculty-developed, state-wide, high-stakes assessment of pre-service teachers' knowledge and application of research based literacy practices. The literacy faculty control all aspects of the test, including construction, refinement, administration, scoring and reporting. The test development…

This report is the second part of a study designed to construct a test for measuring musical aptitude of persons from various age groups. It covers the construction of the test, material, item analysis, reliability, validity, and possible future steps. The test is composed of musical recordings, determined from pilot studies, that the test groups…

Analyzed published data on the Wechsler Adult Intelligence Scale (WAIS) to ascertain whether the Information and Vocabulary subtests can function as measures of intelligence. Concluded that the addition of more WAIS subtests will not result in any increase in predictive validity and these additional tests, therefore, lack incremental validity.…
