Teacher Evaluation as a Function of Leadership Style: A Multiple-Correlational Approach

Description: One of the most persistent issues in contemporary organizations has been how to evaluate individual performance. Basically, the problem is who should evaluate whom and against what productivity criterion. Educational institutions have been the organizations most concerned with this dilemma in recent years. As recently as September, 1973, teachers went on strike over accountability procedures. This study was conducted to identify which mode of teacher evaluation was most efficient, based on fairly objective performance criterion, and to establish a basis for viewing teaching style as leadership style. In existing research, superior ratings were the most used evaluation measure, student ratings were a rapidly growing mode of evaluation, self-ratings were considered biased, and peer ratings were used very little. Hence, who should do the evaluating was an unsolved problem. All four evaluation modes were employed in the present study for comparison.

Identification of highly gifted 5- and 6-year-old children: Measures to predict academic achievement.

Description: Studies indicate the educational needs of highly gifted students are best met through accelerated learning. It is difficult to recognize very young children that are suited for an accelerated curriculum because younger students frequently lack school records or portfolios used to identify gifted students. This study examined the accuracy of cognitive ability and achievement tests in predicting academic achievement by the end of second grade, correlating test results and final grade averages collected from sixteen children ages five to six who entered a public school program for high-ability learners in kindergarten. A multiple regression analysis indicated the Wechsler Preschool and Primary Scale of Intelligence produced the highest mean IQ score and a strong correlation with reading achievement. The Wechsler Individual Achievement Test contributed in small part to the prediction of academic achievement. The Naglieri Nonverbal Ability Test and the Kaufman Brief Intelligence Test-Second Edition had negative correlations with final grade averages, indicating they are not predictors of academic achievement for these students.

The Big Five Personality Characteristics of World of Warcraft Players

Description: This study is a comparative analysis of the personality characteristics of a sample of World of Warcraft players (n = 147) and a large normative sample (n = 20,993). The 120-item International Personality Item Pool, based on the five factor model, is used. Independent t-tests were conducted and statistical significance was found for some factors; however, the effect sizes were small, indicating a limited practical difference between the two groups.

A Comparative Study of Advanced Placement and Learning Differenced Students: Comparing Internal Attribution and Correlation to Hopefulness.

Description: The goal of this research was to determine if there are significant differences in the attribution styles for positive and negative events between students of differing ability and the correlation of these attribution styles to hopefulness. The study examined twelfth grade advanced placement (AP N = 45) students and twelfth grade students with documented learning differences enrolled in college preparatory classes (CP-LD N = 14). Both groups of students came from high socioeconomic backgrounds. The students' internal attributions related to hopefulness were measured with the Hope Scale (Snyder, 1994) which assesses the constructs of agency (will), pathway (way), and produces an overall hopefulness score. Results indicate that AP and CP-LD students had similar measures of internal attribution for positive events, but significantly distinct measures of internal attribution for negative events. However, the AP students show no statistically significant difference from CP-LD students in their measures of agency, pathway, or overall hopefulness.

A Performance Evaluation of Confidence Intervals for Ordinal Coefficient Alpha

Description: Ordinal coefficient alpha is a newly derived non-parametric reliability estimate. As with any point estimate, ordinal coefficient alpha is merely an estimate of a population parameter and tends to vary from sample to sample. Researchers report the confidence interval to provide readers with the amount of precision obtained. Several methods with differing computational approaches exist for confidence interval estimation for alpha, including the Fisher, Feldt, Bonner, and Hakstian and Whalen (HW) techniques. Overall, coverage rates for the various methods were unacceptably low with the Fisher method as the highest performer at 62%. Because of the poor performance across all four confidence interval methods, a need exists to develop a method which works well for ordinal coefficient alpha.

Comparison of Heterogeneity and Heterogeneity Interval Estimators in Random-Effects Meta-Analysis

Description: Meta-analyses are conducted to synthesize the quantitative results of related studies. The random-effects meta-analysis model is based on the assumption that a distribution of true effects exists in the population. This distribution is often assumed to be normal with a mean and variance. The population variance, also called heterogeneity, can be estimated numerous ways. Accurate estimation of heterogeneity is necessary as a description of the distribution and for determining weights applied in the estimation of the summary effect when using inverse-variance weighting. To evaluate a wide range of estimators, we compared 16 estimators (Bayesian and non-Bayesian) of heterogeneity with regard to bias and mean square error over conditions based on reviews of educational and psychological meta-analyses. Three simulation conditions were varied: (a) sample size per meta-analysis, (b) true heterogeneity, and (c) sample size per effect size within each meta-analysis. Confidence or highest density intervals can be calculated for heterogeneity. The heterogeneity estimators that performed best over the widest range of conditions were paired with heterogeneity interval estimators. Interval estimators were evaluated based on coverage probability, interval width, and coverage of the estimated value. The combination of the Paule Manel estimator and Q-Profile interval method is recommended when synthesizing standardized mean difference effect sizes.

Therapeutic and Educational Effects of Writing an Autobiography in an Undergraduate Developmental Psychology Course

Description: The purposes of this study were to investigate the possible therapeutic and educational effects of writing an autobiography in an undergraduate developmental psychology course, to explore the role of structure in writing an autobiography, and to determine if any significant sex differences exist in the effects of writing an autobiography.
