Sample size recommendations in confirmatory factor analysis (CFA) have recently shifted away from observations per variable or per parameter toward consideration of model quality. Extending research by Marsh, Hau, Balla, and Grayson (1998), simulations were conducted to determine the extent to which CFA model convergence and parameter estimation…

A sample of 917 children, aged 7 to 17 years, their parents, and their teachers each completed the appropriate version of the Strengths and Difficulties Questionnaire (SDQ), and 120 from each group did so again 2 weeks later. The results indicate that the SDQ demonstrates sound interinformant and test-retest reliability. Younger children, whose…

Marking reliability is purported to be produced by having an effective community of practice. No experimental research has been identified which attempts to verify empirically the aspects of a community of practice that have been observed to produce marking reliability. This research outlines what that community of practice might entail and…

The commentaries include a wealth of insightful and interesting observations and suggestions, and I appreciate each author taking the time to comment on my efforts. In responding to their suggestions, I am inclined to develop a few general points raised in the commentaries a bit further.

Two experiments examined whether listening to multiple presentations of recorded speech stimuli influences the reliability and accuracy of judgments of children's speech production accuracy. In Experiment 1, 10 listeners phonetically transcribed words produced by children with phonological impairments after a single presentation and after the word…

This investigation assesses interobserver agreement on conversation analytic (CA) transcription. Four professional CA transcribers spent a maximum of 3 hours transcribing 2.5 minutes of a previously unknown, naturally occurring, mundane telephone call. Researchers unitized transcripts into words, sounds, silences, inbreaths, outbreaths, and laugh…

Using survey results compiled from an extensive study into the ethical decision making of school principals, this article analyses the nature and consistency of principals' ethical decision-making processes. Based on the findings, the article argues that even though principals on the whole have well-meaning intentions, by and large, they do not…

This article offers an alternative methodology for practitioners and researchers to use in establishing interrater reliability for testing purposes. The majority of studies on interrater reliability use a traditional methodology where by two raters are compared using a Pearson product-moment correlation. This traditional method of estimating…

Because nominal-scale judgments cannot directly be aggregated into meaningful composites, the addition of a second rater is usually motivated by a desire to estimate the quality of a single rater's classifications rather than to improve reliability. When raters agree, the aggregation problem does not arise. Nevertheless, a proportion of this…

Purpose: We designed this study to examine the reliability of the nursing home survey process in the state of Kansas using regular and simultaneous survey teams. In particular, the study examined how two survey teams exposed to the same information at the same time differed in their interpretations. Design and Methods: The protocol for…

This report summarizes findings from a two-year study of Chicago's Excellence in Teaching Pilot, which was designed to drive instructional improvement by providing teachers with evidence-based feedback on their strengths and weaknesses. The pilot consisted of training and support for principals and teachers, principal observations of teaching…

Due to the alarming signals of declining proficiency level among English Language learners in Malaysia, this study set out to learn more about the learners' perceptions of the teachers' code-switching in English Language classrooms. The objectives of this study were to investigate: a) learners' perceptions of teachers' code-switching, b) the…

For Americans to engage in a global information society, it is critical that they have access to high-speed, high-bandwidth Internet, meaning broadband. Network connectivity opens up a wealth of possibilities to K-12 educators. While it has the potential to result in fundamental changes in teaching methods, it can definitely be used to enhance…

College access can be defined as the successful transition from high school to college, leading to successful completion of a college degree. This study focuses on how much support for college-going students receive while in high school. Previous research has found that group differences in college-going rates are related to differences in social…

Background: Persistent calls for school-based education about stuttering necessitate a better understanding of peer attitudes toward children who stutter and a means to measure outcomes of such educational interventions. Langevin and Hagler in 2004 developed the Peer Attitudes Toward Children who Stutter scale (PATCS) to address these needs and…
