Sample size and statistical power are important factors to consider when planning a research synthesis. Power analysis methods have been developed for fixed effect or random effects models, but until recently these methods were limited to simple data structures with a single, independent effect per study. Recent work has provided power…

The popularity of online surveys has increased the prominence of using weights that capture units' probabilities of inclusion for claims of representativeness. Yet, much uncertainty remains regarding how these weights should be employed in analysis of survey experiments: Should they be used or ignored? If they are used, which estimators are…

Using instructional variables identified by the literature as important in predicting classroom achievement, a bi-polar rating scale was designed to assess the structure of instruction in resource rooms. The data for 158 elementary school children in four school districts were analyzed. The scale evidenced good reliability, both in terms of…

Texts on measurement theory report many studies on the consistency of intelligence test scores, but the stability of academic achievement over the school years has never been adequately studied. To investigate the stability of achievement test scores from fourth grade to college, a random sample of 100 students was selected from a 1978 graduating…

Examined the accuracy and validity of self-reports and their effect on tests of attitude-behavior relationships. Self-reports were reasonably accurate, but they produced results different from actual behavior in attitude-behavior tests. Concludes that self-reports and actual behavior should be measured, tested, and modeled separately. (Author/LS)

Greek parents (N=320) were given the Child Abuse Potential (CAP) Inventory and results were compared with American scores. Internal consistency reliability was high for four scales (abuse, distress, rigidity, and inconsistency). The Greek and American versions had similar factorial structures. Comparison found that Greek scores were significantly…

A 12-item acculturation scale developed for Hispanics correlated highly with the respondents' generation, length of residence in the United States, age at arrival, ethnic self-identification, and with an acculturation scale. Language use, media preferences, and ethnic social relations were the three factors accounting for 67.6 percent of the total…

Addresses the validity of the Cognitive-Affective Response Test-Music by clarifying the theoretical assertions on which the construct validity of the instrument rests. Presents nine specific assertions and data from two studies. Concludes that the test is valid for college-bound high school students. (CFR)

A study was conducted to determine if a teacher-constructed cloze procedure correlated significantly with two standardized tests of reading achievement, thereby testing G.D. Spache's claim that most teachers are unable to design valid and reliable assessment materials. Subjects were 60 fourth and sixth grade students who were administered the…

A study examined screening measures that are used to predict whether a student will teach after graduation from an agricultural education program. The population for the study consisted of 72 student teachers studying in the Department of Agricultural Education at the University of South Florida from 1977 to 1982. Before starting student teaching,…

The Efficacy Scale for Creative Productivity (ESCreP) was developed to measure students' convictions that they could be creative producers. Self-efficacy, an individual's estimation of ability to perform a behavior, is based upon performance accomplishments, vicarious experiences, verbal persuasion, and emotional or physiological arousal. Three…
