Although research has provided a substantial amount of information about key characteristics of effective school leaders, there is a growing need for continued improvement and reflective practice on the continuous development of instructional leaders. The purpose of this study was to determine to what extent elementary principals perceive they are…

Background: In recent years, withdrawal from initial teacher preparation (ITP) programmes, in England and elsewhere, has become a cause for concern amongst both ITP providers and policy-makers. Purpose: This paper seeks to enhance the presently underdeveloped evidence base on the causes of withdrawal from ITP and on the characteristics of student…

Distance Education has globally become one of the important solutions for increasing admission into the universities, decongesting campuses and efficient utilization of time and space. To ensure the sustainability of the programmes' noble objectives calls for periodic re-evaluation of its modus operandi including the assessment of the perception…

This article explores the effects of the Time To Know program, a comprehensive technology-rich learning environment, on low socio-economic status (SES) students' learning achievements in Mathematics, Hebrew, and English as a Foreign Language (EFL)in Israel. The study is based on the assumption that one of the possible solutions for bridging the…

Patterns of classes, grades, and test scores were studied in 3 successive graduating classes of a mid-western suburban high school. Descriptive statistics indicate that the prestigious college group had the highest mean scores on 23 variables. Descriptive discriminant analysis revealed the most influential variables were cumulative grade point…

In the United States, there is an alarming trend toward obesity and inactivity among children. Minorities and economically disadvantaged children are at an even higher risk. According to the Centers for Disease Control and Prevention one in two Latino children will become diabetic. As a result, there is a dire need for tailored intervention…

The purpose of this study was to investigate the effectiveness of concept mapping strategies with different levels of generativity in terms of knowledge acquisition and knowledge representation. Also, it examined whether or not learners' self-regulated learning (SRL) skills influenced the effectiveness of concept mapping strategies with different…

Intermediate learners of Spanish read a Spanish newspaper article with vocabulary assistance either before reading, while reading, both, or without any such assistance. Reading performance was significantly better for students receiving vocabulary assistance during reading, but not for those receiving it before reading. Reading time of the…

Contrary to popular opinion, significance testing does not inform the researcher of the likelihood of the replication of results from current research findings. Result replicability has been ignored by researchers because of an overreliance on significance testing. Several alternatives have been offered to provide the researcher with more…

Virtually all parametric statistical procedures have been shown to be special cases of canonical correlation analysis, which is a useful research methodology particularly when augmented by the calculation of canonical structure, index, and invariance coefficients. A logic for conducting stepwise canonical correlation analysis based upon evaluation…

A definition of a suppressor variable is presented which is based on the relation of the semipartial correlation to the zero order correlation. Advantages of the definition are given. (Author/JKS)

The relationship between quantitative predictor variables and the probability of occurrence of one or more levels of a qualitative criterion variable can be analyzed by quantal response techniques. This paper presents and discusses two quantal response models, comparing them to multiple linear regression and discriminant analysis. (Author/JKS)

Applied statistical methods to predict case expenditures for low back pain rehabilitation cases in proprietary rehabilitation. Extracted predictor variables from case records of 175 workers compensation claimants with some degree of permanent disability due to back injury. Performed several multiple regression analyses resulting in a formula that…

Describes the method of discriminant analysis, including the concept of discriminant function, discriminant score, group centroid, and discriminant weights and loadings. Discusses methods for testing the statistical significance of a function, methods of using the function in classification, and the concept of rotating functions. Illustrates the…

Modeled the intake decisions of four clinicians at a community mental health center by principal components-discriminant function analysis. Results showed that clinicians' written notes can predict decisions. Cues most important in arriving at intake decisions were therapy history, interview site, level of functioning, diagnosis, and behavioral…
