This dissertation was designed to explore the impact of the identified responsibilities of the principal, as an instructional leader, within the professional development model of Reading First. Specifically, the research focused on the principals' use of the Observation and Constructive Feedback Processes as well as five specifically defined…

The sense that replicability is an important aspect of empirical science led Killeen (2005a) to define "p[subscript rep]," the probability that a replication will result in an outcome in the same direction as that found in a current experiment. Since then, several authors have praised and criticized 'p[subscript rep]," culminating…

This comment offers three descriptions of "p[subscript rep]" that start with a frequentist account of confidence intervals, draw on R. A. Fisher's fiducial argument, and do not make Bayesian assumptions. Links are described among "p[subscript rep]," "p" values, and the probability a confidence interval will capture…

The purpose of this investigation was to examine the types of preparation that students used to prepare for the Texas Examination for Educators Standards (TExES) Examination. Specifically, this study was concerned with the different types of preparation methods that impact test scores based on gender, ethnicity, age and specialization. The…

The Protestant Reformation swept across Central Europe in the early-sixteenth century, leaving cities divided into Evangelical and Catholic camps as some instituted reforms and others remained loyal to the Roman Church. In offering a new explanation of the Reformation, we develop a theory that identifies ideologically mobilized students as bridge…

The purpose of this research is to ascertain whether or not there is a relationship between accreditation method and institutional performance as measured by the institutions' graduation rates and retention rates. More specifically, this research will provide empirical evidence of the relative performance of institutions that are Academic Quality…

As online education has grown rapidly, colleges and universities have developed various approaches to effectively evaluating and coaching faculty. Faculty performance is central to student success and faculty need feedback that is consistent, constructive and illustrative. Through the use of screen recording technology, academic department chairs…

The problem. This study investigated whether there were statistically significant differences in perceptions of high school students with specific learning disabilities with respect to reasons for either remaining in high school or leaving high school on their 18th birthday. Method. A quasi-experimental study was conducted. 30 students who were…

The use of visual aids is expected to have a positive effect on students' learning. However, not all visual aids work equally well. A recent meta-analytic research which examined 42 studies has found that the use of animated visuals does not facilitate learning (Anglin, Vaez & Cunnincham, 2004). The failure of visual aids can be attributed to…

We are grateful to the commentators for providing many stimulating and valuable observations. The main point of our article was to call attention to the overestimation of individual differences correlations in a subset of neuroimaging papers. To structure our discussion of these comments, we list the main points from our paper, note where…

This report presents guidelines for addressing the multiple comparisons problem in impact evaluations in the education area. The problem occurs due to the large number of hypothesis tests that are typically conducted across outcomes and subgroups in these studies, which can lead to spurious statistically significant impact findings. The…

A walk through Milne's Enchanted Forest leads to an unexpected encounter with hypothesis testing.

Hypothesis testing is one of the more difficult concepts for students to master in a basic, undergraduate statistics course. Students often are puzzled as to why statisticians simply don't calculate the probability that a hypothesis is true. This article presents an exercise that forces students to lay out on their own a procedure for testing a…

It is shown that the rank-biserial correlation coefficient is a linear function of the U-statistic (Mann and Whitney), so that a test of group mean difference is equivalent to a test of zero correlation for the rank-biserial coefficient. (RC)

The research indicates that there are many benefits to pre-kindergarten participation which includes positive social and emotional benefits and academic achievement gains (Barnett et al., 2005; Cody, 1993; Neuman, 2007; U.S. Dept. of Health & Human Services, 2010). The purpose of this quantitative study was to examine the effects of the…
