Levels of hostility and type of crime were compared in 94 male offenders with 3-4 or 4-3 Minnesota Multiphasic Personality Inventory (MMPI) high point pairs and in randomly selected offenders without these pairs. Results do not support these codes as evidence of a proclivity for violence. (SLD)

Addresses issues faced by institutions attempting to design school profiles to meet accountability standards. Reports of high-stakes test results can be skewed by choice of statistic type (percent of students passing versus mean scores), sample bias, geographical transients, and omission errors.

The purpose of this study was to determine the knowledge levels of popular biotechnological issues of Turkish science and elementary teacher candidates. A questionnaire was administered during 2006-2007 school term to 336 students pursuing their education in the departments of science and elementary education in two Turkish universities. The…

Relatively few experimental studies have examined the effectiveness of study guides on student exam performance. The authors compared exam scores for students who were given instructor-generated study guides versus students who generated their own study guides. Participants were undergraduates enrolled in three identical sections of an…

The study evaluated the comparability of two versions of a certification test: a paper-and-pencil test (PPT) and computer-based test (CBT). An effect size measure known as Cohen's d and differential item functioning (DIF) analyses were used as measures of comparability at the test and item levels, respectively. Results indicated that the effect…

As the number of learning support assistants (also referred to as classroom assistants, teaching aides, auxiliary support and paraeducators) employed in the primary sector continues to increase, questions concerning the contribution they make to raising standards of attainment remain to be answered. This article reports evidence from a small-scale…

Empirical studies addressing admission to and graduation from a doctoral program focusing on educational leadership are noticeably absent within the professional literature, and this study seeks to fill partially this void through testing specific hypotheses.

A Monte Carlo study examined the statistical performance of single sample and bootstrap methods that can be used to test and form confidence interval estimates of indirect effects in two cluster randomized experimental designs. The designs were similar in that they featured random assignment of clusters to one of two treatment conditions and…

This study examined whether children's reading rate, comprehension, and recall are affected by computer presentation of text. Participants were 60 grade five students, who each read two expository texts, one in a traditional print format and the other from a computer monitor, which used a common scrolling text interface.
