The purpose of the current investigation was to describe how the artificial neural networks (ANNs) can be used to interpret student performance on cognitive diagnostic assessments (CDAs) and evaluate the performances of ANNs using simulation results. CDAs are designed to measure student performance on problem-solving tasks and provide useful…

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…

Much of the argument about comparability of examination standards is at cross-purposes; contradictory positions are in fact often both defensible, but they are using the same words to mean different things. To clarify this, two broad conceptualisations of standards can be identified. One sees the standard in the observed phenomena of performance…

Test developers are responsible to define how test scores should be interpreted and used. The No Child Left Behind Act of 2001 (NCLB) directed the Secretary of Education to use results from the National Assessment of Educational Progress (NAEP) to confirm the proficiency scores from state developed tests. There are two sets of federal definitions…

Robert Coe has claimed that three broad conceptions of comparability can be identified from the literature: performance, statistical and conventional. Each of these he rejected, in favour of a single, integrated conception which relies upon the notion of a "linking construct" and which he termed "construct comparability".…

Two methods are presented for comparing distributions, such as achievement test score distributions, for distinctly different groups of persons in such a way that the comparison will not be influenced by the particular metric of the test being used. Both methods use percentile scores. One method, attributed to Flanagan, fits a straight line to the…

Comparisons of majority and minority group regression lines for purposes of assessing test bias may, under certain conditions, be viewed as comparisons of conditional bivariate distributions. Where these conditions hold, findings should reveal parallel regression lines except for a special case. Given the conditions described, one implication is…

Correlates that describe in part the variation of conditions under which learning is attempted are discussed. Each of these correlates is significantly related to student achievement. Categories into which the correlates are grouped are: Socioeconomic Status Variables (mother's occupation, father's occupation, mother's educational level, father's…

A study examined the appropriateness of two methods for relating the enhanced American College Testing Program (ACT) Assessment Composite and Scholastic Aptitude Test (SAT) total scores: equipercentile concordance and regression. Study results, potential inaccuracies, and the usefulness of institutional concordances based on their own data are…

Rasch model vertical equating procedures were applied to three mathematics computation tests for grades six, seven, and eight. Each level of the test was composed of 45 items in three sets of 15 items, arranged in such a way that tests for adjacent grades had two sets (30 items) in common, and the sixth and eighth grades had 15 items in common. In…

Differences among states' average SAT scores are almost entirely attributable to differences in percentage of test takers, parent education and income of test takers, and the high school rank and GPA of the test takers rather than to the quality of the states' education systems. Recommends changes in interpreting and reporting SAT scores.…

Prior use of the equipercentile method of test equating was based on a graphic procedure which is tedious, subject to smoothing errors, and non-analytical. Recognition of the equipercentile method as a curve-fitting procedure for two cumulative percentage distributions leads to a proposed analytical solution to the problem through use of linear…

This study examines a common set of equating items for their appropriateness to both American and Canadian populations and, to determine the equations for converting scores from the verbal and mathematical scales of the 1971 form of the Canadian Scholastic Aptitude Test (the future standard continuing scales of the CSAT) to the corresponding…

This study was concerned with determining the validity of the Slosson Intelligence Test (SIT) using the Stanford-Binet Intelligence Scale (S-B), Form L-M as the validity criterion. The sample consisted of 724 students enrolled in 10 public school systems in northeastern Massachusetts. Using the Pearson-Product Moment formula a coefficient of…
