Development of a research instrument to measure student achievement requires planning and reliability and validity testing before the instrument is used to collect data. These steps are often overlooked in research studies, but when the instrument is to be used across a wider population, the inclusion of these steps is vital to address the…

The purpose of this study was to develop a valid and reliable scale for preferences of teachers in regard of their curriculum design orientations. Because there was no scale development study similar to this one in Turkey, it was considered as an urgent need to develop such a scale in the study. The sample of the research consisted of 300…

As educational technology practitioners and researchers engage in research in the field, a wide array of research methodologies are available to them. One such methodology is the Delphi Technique. Use of the Delphi Technique offers many benefits, including the ability to obtain expert opinion, build consensus, determine the suitability of the…

Students with internalizing behavior patterns are often overlooked and underserved in schools, which is problematic in that they are at risk for a host of negative outcomes. As a result, there is a need for universal screening procedures to proactively detect students with these behavior patterns and to provide them with early, ongoing supports.…

Although reliability is essential to validity, most research on violence risk assessment tools has paid little attention to strategies for improving rater agreement. The authors evaluated the degree to which perceived subjectivity in scoring guidelines for items from two measures--the Psychopathy Checklist-Revised (PCL-R) and the Historical,…

The aim of this study is to develop a valid and reliable scale that can be used in determining educational beliefs of teachers and prospective teachers. After studies such as scale expert views and the evaluation of intelligibility, the measure is administered to a sample consisting of 154 teachers and 305 prospective teachers with a total number…

In this study, the authors developed the Adult Scale of Hostility and Aggression Reactive-Proactive (A-SHARP). Sixty-one caregivers rated 512 individuals with intellectual and developmental disabilities on the A-SHARP. Exploratory factor analysis revealed 5 factors on the Problem Scale: (a) Verbal Aggression, (b) Physical Aggression, (c) Hostile…
