The Instructional Practices Log in Science (IPL-S) is a daily teacher log developed for K-5 teachers to self-report their science instruction. The items on the IPL-S are grouped into scales measuring five dimensions of science instruction: "Low-level Sense-making," "High-level Sense-making," "Communication,"…

Visual display of reported impacts is a valuable aid to both reviewers and readers of systematic reviews. Forest plots are routinely prepared to report standardised effect sizes, but where standardised effect sizes are not available for all included studies a forest plot may misrepresent the available evidence. Tabulated data summaries to…

Growing life expectancy and changes in financial, marriage and labour markets have placed the income position of the elderly at the center of scientific and political discourse. As a consequence, the last decades witnessed the publication of various influential reports that contained comparative statistics on old age income inequalities on the…

Although response to intervention (RTI) has been widely discussed in education literature and is increasingly being implemented in schools throughout the U.S., few studies provide empirical evidence of improved school-wide student outcomes. Presented here are data and an effect size analysis of school-wide student reading gains in five elementary…

This study applies the theory of planned behavior (TPB), a theory that is commonly used in commercial settings, to the educational context to explain pre-service teachers' technology acceptance. It is also interested in examining its validity when used for this purpose. It has found evidence that the TPB is a valid model to explain pre-service…

The aim of this study is to develop a scale to predict intimate partner femicide and severe violence. The sample consists of 1,081 batterer men who were reported to the police station. First, the most significant differences between the severe violence group (n = 269) and the less severe violence group (n = 812) in sociodemographic variables are…

Background: The risk of developing a negative attitude to communication as a consequence of having a speech disorder has been in focus for decades in research concerning fluency disorders in relation to both children and adults. The Communication Attitude Test (CAT), which was created to measure children's attitudes towards their own…

Objective: The Evaluation Self-Efficacy Scale (ESE) is being developed as an outcomes assessment instrument for social work courses focusing on evaluation. Method: This scale, based on social cognitive theory, was pretested, revised, and then used with a final sample of 85 master's-level students in the original study. Using a single-group,…

The question of whether or not block size has an effect on the statistical analysis of data is examined through a study involving a total of 10,000 simulated experiments. Results indicate that the inflation in Type 1 error rate is much higher than is reported in the literature when using CE as the independent variable. There is little or no…

Valid statistical tests for one-subject experiments are necessary to justify statistical inferences and to ensure the acceptability of research reports to a wide range of journals and readers. The validity of randomization tests for one-subject experiments is examined. (See TM 505 800-801).(Author/JKS)

Broad trends in occupational employment have been projected fairly accurately by the Bureau of Labor Statistics and significant improvements have been made in procedures for developing projections. However, accuracy has not increased over time. (JOW)

The trend towards using screening programs to facilitate early identification of developmental or learning problems has accentuated the need to establish reliable and valid screening procedures. Researchers in this area must recognize that the dichotomous decision-making function of screening (i.e., to refer or not refer a child for further…

A sample of library-output statistics measuring circulation, reference, and in-library use was collected from 76 libraries and tested for redundancy, correlation, and variation using time-series analysis to test the Relative Fidelity of Measurement Model (RFM). The 275 sample statistics correlated in an unpredicted pattern. Twenty-three sources…

Default on guaranteed student loans has been increasing. The use of discriminant analysis as a technique to identify "good" v "bad" student loans based on information available from the loan application is discussed. Research to test the ability of models to such predictions is reported. (Author/MLW)

This study further develops the Diagnostic Survey for Leadership Improvement (DSLI) and determines its reliability and validity. Split-half estimates of the DSLI's reliability were computed. These estimates came in terms of the Pearson product-moment correlation coefficients that were then corrected by the Spearman-Brown Prophesy Formula. The…
