This exploratory study investigated potential sources of setting accommodation resulting in differential item functioning (DIF) on math and reading assessments for examinees with varied learning characteristics. The examinees were those who participated in large-scale assessments and were tested in either standardized or accommodated testing…

Many measurement biases affect student evaluations of instruction (SEIs). However, two have been relatively understudied: halo effects and ceiling/floor effects. This study examined these effects in two ways. To examine the halo effect, using a videotaped lecture, we manipulated specific teacher behaviors to be "good" or "bad"…

This study investigates the effect of mode of administration of the Raven Standard Progressive Matrices test on distribution, accuracy, and meaning of raw scores. A random sample of high school students take counterbalanced paper-and-pencil and computer-based administrations of the test and answer a questionnaire surveying preferences for…

The Computer Anxiety Scale (CAS) measures the perceptions of individuals with respect to their anxiety toward computers. Although the CAS was developed a number of years ago, research has shown that its factor structure has remained stable. Recent cross-cultural studies using samples of college students from various countries have also shown that…

Analyzed data from 1,467 Australian high school students for the Individualized Classroom Environment Questionnaire (ICEQ) to determine the degree to which ICEQ scores measure aspects of classroom climate as opposed to individual student attitude. Results support the use of the ICEQ as a measure of classroom climate. (SLD)

Effects of randomly distributing attitude-measurement items throughout a questionnaire (personality format) versus grouping together items from the same dimension (achievement format) on students' end-of-course evaluations were studied for 376 undergraduates. Advantages demonstrated for the achievement format in terms of statistical results,…

The convergent validity of peer, self, and teacher methods of assessing youths' risk propensity and the relation of these measures to health risk behavior were studied with 436 elementary and junior high school students. Findings demonstrate low congruence between rater sources. Prediction depended on behavior assessed and grade level. (SLD)
