A more general method for calculating the Kappa measure of nominal rating agreement among multiple raters is presented. It can be used across a broad range of rating designs, including those in which raters vary with respect to their base rates and how many subjects they rate in common. (Author/BW)

Post hoc multiple comparison procedures useful in assessing differences in population variability are formulated for three nonparametric alternatives to the parametric Bartlett test. The three nonparametric tests are the generalized Puri K-sample extensions of the Siegel-Tukey, mood, and Klotz tests. (Author/CTM)

Provides tables of critical values for determining statistically significant discrepancies between Wechsler Verbal/Performance IQ and Wechsler Individual Achievement Test subtests and composite scores based on predicted-achievement method. Recommends that tables be used when statistically significant and diagnostically meaningful Verbal…

Provides an overall test statistic to evaluate significance that yields 100% (1-alpha) confidence intervals for all linear combinations of effect sizes, shows how the stepdown Finite Intersection Test (N. Timm, 1995) may be used to test whether effect sizes are simultaneously different from zero, and illustrates the procedure. (SLD)

Presents an adaptive approach to multiple significance testing based on the procedure of Y. Benjamini and Y. Hochberg (1995) that first estimates the number of true null hypotheses and then uses that estimate in the Benjamini and Hochberg procedure. Uses the new procedure in examples from educational and behavioral studies and shows its control of…

Meares-Irlen Syndrome (MIS) is characterised by symptoms of visual stress and visual perceptual distortions that are alleviated by using individually prescribed coloured filters. Coloured overlays (sheets of transparent plastic that are placed upon the page) are used to screen for the condition. MIS is diagnosed on the basis of either the…

Employees with greater control over their own activities have better health. People who are employed give up some control over their own activities for pay, yet employment is associated with better health. Perhaps paid jobs provide resources for productive self-expression that make up for the loss of autonomy. We find that paid employment is…

Confidence intervals are widely accepted as a preferred way to present study results. They encompass significance tests and provide an estimate of the magnitude of the effect. However, comparisons of correlations still rely heavily on significance testing. The persistence of this practice is caused primarily by the lack of simple yet accurate…

With declining state support, increased financial need on the part of the fastest growing demographic sections of the population, and public policy that discourages major increases in tuition for public higher education, the only logical source of additional finances for public colleges and universities is increased private funding through…

This study examined the effects of being taught the Mayfield's Four Questions multiple-choice test-taking strategy on the perceived self-efficacy and multiple-choice test scores of nursing students in a two-year associate degree program. Experimental and control groups were chosen by stratified random sampling. Subjects completed the 10-statement…

Culture tends to be misplaced as a secondary instructional goal in most foreign language classrooms. Although research has suggested that a strong link exists between language and culture, the problem resides in how best to teach culture in the classroom. While this problem impacts all learners, it may affect high school students more because they…

The present study investigated the extent to which providing students with individualized performance feedback informed and directed their learning behavior. Individualized performance feedback was delivered to students using curriculum-based measurement progress indicators, either as a visual representation of ongoing performance in the form of a…

Tennessee Code Annotated 49-5-108 specifies that the State Board of Education "with the assistance of the department of education and the Tennessee higher education commission, shall develop a report card or assessment on the effectiveness of teacher training programs." The State Board is directed to "annually evaluate performance…

The No Child Left Behind (NCLB) Act provides support "to ensure that teachers have the necessary subject matter knowledge and teaching skills in the academic subjects that the teachers teach." Title II of the act allows funds to be used for "carrying out programs that establish, expand, or improve alternative routes for state…
