No significant difference in beginning ninth-grade pretest compared to ending ninth-grade posttest comparisons of American History t(17) = 0.34, p = 0.37 (one-tailed), d = 0.09, English t(17) = 1.40, p = 0.09 (one-tailed), d = 0.34, and Biology (t(17) = -1.58, p = 0.07 (one-tailed), d = -0.22, course grade scores were observed for students…

The purpose of this study was to examine the effects of Accelerated Math utilization on students' grade equivalency scores. Twelve students for both experimental and control groups were randomly selected from 37 students enrolled in math in grades four through six. The experimental group consisted of the students who actively participated in…

The teacher's task of assigning letter grades to students and the public's interpretation of them can be perplexing. Does the student's grade represent the level of achievement, the gain in achievement, or some combination of the two? Is the student's effort included in the grade, or are high achievers given good marks regardless of effort? Are…

We examined whether the General Factor of Personality (GFP) is related to the "g" factor of cognitive ability using data from the Vietnam Experience Study which randomly sampled 4462 Vietnam War veterans from a total sample of about five million Vietnam era army veterans. Exclusionary criteria included passing a fitness test, achieving a final…

This article examines how international differences in age-grade distributions and grade effects contribute to science scores among 27 Organization for Economic Cooperation and Development countries. As shown in the 2006 Program for International Student Assessment, countries vary substantially in the grade distribution of 15-year-olds. The costs…

The present study was initiated to gather information about states' out-of-level testing practices. Specifically, we wanted to see whether states attempted to align out-of-level tests with grade of enrollment content standards, what processes are used to complete this task, and what psychometric information states offer as evidence of that…

The purpose of this research study was to illustrate the ways in which out-of-level testing policies have changed over the three years from 2000-2001 to 2003-2004. In 2000-2001, 12 states were using out-of-level tests to measure student progress toward content standard proficiency. A detailed research study conducted at the end of 2000-2001 to…

We tested the hypothesis that highly structured course designs, which implement reading quizzes and/or extensive in-class active-learning activities and weekly practice exams, can lower failure rates in an introductory biology course for majors, compared with low-structure course designs that are based on lecturing and a few high-risk assessments.…

Most researchers agree that psychological/educational tests are sensitive to multiple traits, implying the need for a multidimensional item response theory (MIRT). One limitation of applying a MIRT in practice is the difficulty in establishing equivalent scales of multiple traits. In this study, a new MIRT linking method was proposed and evaluated…

Motivating students to perform well on assessment tests is difficult when students know the results have no academic consequence. The present study evaluates the influence of assessment context (graded vs. non-graded) on the reliability of an assessment measure. Results indicate the graded condition produces higher reliability (r = 0.71) than the…

Compared the observation of children's growth in reading using grade equivalents with that using the Rasch simultaneous vertical equating procedure. Results from equating 25 reading tests show that grade equivalents differ more between two different test forms than do ability measures obtained from the Rasch simultaneous vertical equating. (SLD)

It has long been a part of psychometric lore that the variance of children's scores on cognitive tests increases with age. This "increasing-variance" phenomenon was first observed on A. Binet's intelligence measures in the early 1900s. An important detail in this matter is the fact that developmental scales based on age or grade have served as the…

Grade-equivalent scores are widely used in the school system in reporting students' performance on standardized achievement tests. This paper explores how grade equivalent scores are calculated and interpreted. In addition, the paper examines the limitations of grade-equivalent scores through the use of small heuristic data sets. A…

The problem of determining grades on a common scale for two groups offering a common paper in an examination was examined. Three theoretical methods were offered and the results of applying them to some data provided by the East Midland Regional Examinations Board were compared. (Author/RK)

Discusses how standard scores which are called T-scores are used in grading large courses. The article includes: (1) procedures for calculating the class mean, standard deviation, and the standard score; (2) grade distribution; and (3) validity of an examination. (HM)
