The efficiency of cognitive component skills is typically assessed with speeded performance tests. Interpreting only effective ability or effective speed as efficiency may be challenging because of the within-person dependency between both variables (speed-ability tradeoff, SAT). The present study measures efficiency as effective ability…

Standardized measures are often used as an index of students' reading comprehension and scores have important implications, particularly for students who perform below expectations. This study examined secondary-level students' patterns of responding and the prevalence and impact of non-attempted items on a timed, group-administered,…

Results obtained by the Kudar-Richardson formula (20) adapted for use with R-KW scoring are compared with three other reliability formulas. Based on parallel tests administered at the same sitting the KR (20) estimates are compared with alternate-form correlations and with odd-even correlations adjusted by the Spearman-Brown prophecy formula.…

The validity of current standardized competency tests for writing is in doubt as is the need for such testing at all. Some tests, especially those requiring little writing, may not be testing what they purport to test (content validity). Instructional validity (testing what has actually been taught) raises the issue that what is being tested is…

Many community colleges have a need for a mathematics placement test which tests achievement for initial placement in the different levels of mathematics classes. Merrit College investigated this need by examining the scores of all the entering students who did not complete the mathematics section of the School and College Ability Test which they…

Describes some of the hazards of evaluating timed typewriting by the error cut-off method. (MU)

The Kuder Richardson-20 Formula is shown to be a special case, where each examinee is given sufficient time to answer each item, of a more general formula where each examinee may not be allowed the necessary time. The formula is extended to allow two scores, knowledge and speed, to be extracted from each examinees test score. Using a sample of 82…

This study examined irregularities in reading comprehension (RC) test results at both the individual and aggregate levels, focusing on the effect of test speededness on test scores. Data were taken from results of the Stanford Achievement Test--Seventh Edition (SAT/7), administered during April of 1983 to about 50,000 Palm Beach County (Florida)…

This book considers legal questions, theoretical issues, and practical methods for meeting the assessment needs of students with disabilities. It is comprised of ten chapters and includes test accommodation topics relating to federal and state regulations (including the Individuals with Disabilities Education Act Amendments of 1997), problems…

One of the many criticisms leveled at standardized testing is that the time limits commonly used require a speed component of performance which may act to the disadvantaged of certain culturally defined groups. Recent studies by the authors examined the question of differential time limits and group performance for standardized academic aptitude…

The family of Weibull distributions was investigated as a model for the distributions of response times for items in computer-based criterion-referenced tests. The fit of these distributions were, with a few exceptions, good to excellent according to the Kolmogorov-Smirnov test. For a few relatively simple items, the two-parameter gamma…

The purpose of this practicum was to determine if adult students engaged in training for high technology jobs can realize a time savings if customary or metric units of measure are used for practical mathematical calculations. Two quizzes were developed, and validated, using customary and metric units for the same type of problem, and the time to…
