Purpose: The purpose of this study was to determine the effects of biofeedback on control of nasalization in individuals with typical speech. Method: Forty-eight individuals with typical speech attempted to increase and decrease vowel nasalization. During training, stimuli consisted of consonant-vowel-consonant (CVC) tokens with the center vowels…

This study investigates relationships between self-efficacy, self-regulated learning strategy use and academic performance. Participants were 96 undergraduate students working on projects with three subtasks (idea generation task, methodical task and data collection) in a blended learning environment. Task self-efficacy was measured with…

This research was undertaken to determine if significant relationships exist between teachers' self-reported attitudes, concerns, and efficacy to teach in inclusive classrooms and their actual classroom behaviour in Winnipeg, Canada. Five teachers completed 3 scales measuring their attitudes to inclusion, their level of concerns about teaching in…

Test-based accountability often produces score inflation. Most studies have evaluated inflation by comparing trends on a high-stakes test and a lower stakes audit test. However, Koretz and Beguin (2010) noted weaknesses of audit tests and suggested self-monitoring assessments (SMAs), which incorporate audit items into high-stakes tests. This…

Empowerment has been established as an important factor in resilience in adolescence. It has also been deemed critical for youth with emotional and behavioral disorders to achieve successful outcomes across academic, social, and behavioral domains, especially during a major transition. There is currently one measure used to evaluate empowerment in…

Divergent thinking (DT) tests are very often used in creativity studies. Certainly DT does not guarantee actual creative achievement, but tests of DT are reliable and reasonably valid predictors of certain performance criteria. The validity of DT is described as reasonable because validity is not an all-or-nothing attribute, but is, instead, a…

Biotechnology constitutes one of the most challenging, cutting-edge, and rapidly growing fields in science today. Both the practical implications and the hands-on nature of this "modern science" make the topic of biotechnology an attractive addition to the high school science curriculum. The current study is the first of its kind to…

Statistical analysis is one component that cannot be avoided in a quantitative research. Initial observations noted that students in higher education institution faced difficulty analysing quantitative data which were attributed to the confusions of various variable measurements. This paper aims to compare the outcomes of two approaches applied in…

Latent difference score models (e.g., McArdle & Hamagami, 2001) are extended to include effects from prior changes to subsequent changes. This extension of latent difference scores allows for testing hypotheses where recent changes, as opposed to recent levels, are a primary predictor of subsequent changes. These models are applied to…

Determination of neuropsychological impairment involves contrasting obtained performances with a comparison standard, which is often an estimate of premorbid IQ. M. R. Schoenberg, R. T. Lange, T. A. Brickell, and D. H. Saklofske (2007) proposed the Child Premorbid Intelligence Estimate (CPIE) to predict premorbid Full Scale IQ (FSIQ) using the…

Extensive education research on the contribution of teachers to student achievement produces two generally accepted results. First, teacher quality varies substantially as measured by the value added to student achievement or future academic attainment or earnings. Second, variables often used to determine entry into the profession and…

Student self-report data from 933 Black middle school students and standardized mathematics test scores (SAT-10) were used to examine the relationship among student perceptions of teacher expectations and reform instructional practices, aspects of student motivation, and three student mathematics performance outcomes--time spent studying, expected…

We use data on statewide end-of-course tests in North Carolina to examine the relationship between teacher credentials and student achievement at the high school level. The availability of test scores in multiple subjects for each student permits us to estimate a model with student fixed effects, which helps minimize any bias associated with the…

The relationship between verbal skills and retention among adolescents in substance abuse treatment is understudied. In order to assess verbal predictors of retention, twenty-eight 16-19 year old adolescents in a therapeutic community for substance abuse were evaluated between 30 and 90 days after admission. These adolescents were then followed…

Mounting pressure in the policy arena to improve teacher productivity either by improving signals that predict teacher performance or through creating incentive contracts based on performance--has spurred two related questions: Are there important determinants of teacher productivity that are not captured by teacher credentials but that can be…
