The aim of this study is to compare the results of correlation coefficient estimation of reliability with those obtained through the Bland-Altman plot technique. The scale was first divided into two halves using three different approaches. A linear and high-level relationship was found between the scale scores obtained from the halved forms.…

Background: Meta-analyses of educational interventions have consistently documented the importance of methodological factors related to the choice of outcome measures. In particular, when interventions are evaluated using measures developed by researchers involved with the intervention or its evaluation, the effect sizes tend to be larger than…

Students' expectations for their laboratory coursework are theorized to have an impact on their learning experiences and behaviors, such as engagement. Before students' expectations and engagement can be explored in different types of undergraduate chemistry laboratory courses, appropriate measures of these constructs must be identified, and…

A test battery with two different levels of adaptation is presented: a within-subtest level for the selection of the items in the subtests and a between-subtest level to move from one subtest to the next. The battery runs on a two-level model consisting of a regular response model for each of the subtests extended with a second level for the joint…

The lack of validated autism spectrum disorder (ASD) screening instruments hampers rehabilitation efforts for children with ASD in Africa. In the present study, the psychometric properties of two ASD screening instruments, that have been well-validated in the United States (US) context, were examined in the Ugandan context. These instruments were…

Administrative data are increasingly being used to study inequalities in education. Yet a well-known difficulty with such resources is the limited information they hold. A commonly used proxy for children coming from a low-income background is their eligibility for free school meals, yet this is likely to be of little use in measuring academic…

In recent years, there has been increasing awareness on the benefits of social-emotional competencies (SEC) on Israeli students. A self-report SEL measure tailored to the Israeli context, however, has yet to be developed. This research aims to validate the Social-Emotional Questionnaire for Grades 4-6 (SEQ [G4-6]), a new self-report questionnaire…

Magnet schools have been a main tool or innovation in urban education settings in the United States, originating in the early 1970's and expanding into most large urban districts today (Blank, 1989). While some magnet schools do not rely on a specific criterion to determine entry, many do. This study focuses on such a setting where students must…

Early identification of at-risk students is a critical element of Response to Intervention (RTI) but there are few validated universal screeners for high school mathematics. This study evaluated the effectiveness of the screening system currently in use at one urban Texas public high school and compared its effectiveness to alternate screening…
