The role analytical instrumentation performs in the surveillance and control of the quality of water resources is reviewed. Commonly performed analyses may range from simple tests for physical parameters to more highly sophisticated radiological or spectrophotometric methods. This publication explores many of these types of water quality analyses…

Relaxation as self-control and desensitization were compared to a wait-list control in reduction of rest and other anxieties. Active treatments differed significantly from the control treatment. Subjects in both treatments reported less debilitating test anxiety, whereas desensitization subjects showed greater facilitating test anxiety. (Author)

Changing from the SVIB to the SCII increased the probability of machine-scoring errors. This study examined the accuracy and consistency of SCII profile scores for three commercial scoring agencies. Results indicated improved performance compared with previous studies and suggested that scoring errors should be minimal for the SCII. (Author)

Examined concurrent validity of Stanford-Binet Intelligence Scale, 4th edition (SB IV) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) in a homogeneous, nonexceptional sample of 32 early elementary school children. Findings suggest that SB IV has significant positive relationship with WISC-R. The tests displayed a moderate level…

Because of the great promise of distance learning for delivering cost-effective instruction, there is great interest in determining whether or not it actually is effective, and--more interesting--determining what variables of design and implementation make it more or less effective. Unfortunately, much of the research has been based on simple…

This paper illustrates a method to study rater severity across exam administrations. A multi-facet Rasch model defined the ratings as being dominated by four facets: examinee ability, rater severity, project difficulty, and task difficulty. Ten years of data from administrations of a histotechnology performance assessment were pooled and analyzed…

This study examined the relationship between the internal-external control and text anxiety constructs, and academic achievement. The hypothesis that internals would be more successful academically than externals was not supported. (Author)

The present study tests the hypothesis that greater relationships will be found between similarly named scales on the two instruments when OIS scale ranks rather than lambda scores are correlated with SVIB standard scores. The hypothesis was not confirmed. (Author)
