The credibility of conclusions arrived at in quantitative research depends, to a large extent, on the quality of data collection instruments used to quantify language and non-language constructs. Despite this, research into data collection instruments used in Applied Linguistics and particularly in the thesis genre remains limited. This study…

This meta-analysis explores the correlation between self-assessment (SA) and language performance. Sixty-seven studies with 97 independent samples involving more than 68,500 participants were included in our analysis. It was found that the overall correlation between SA and language performance was 0.466 (p < 0.01). Moderator analysis was…

Over the past decades, the application of Rasch measurement in language assessment has gradually increased. In the present study, we coded 215 papers using Rasch measurement published in 21 applied linguistics journals for multiple features. We found that seven Rasch models and 23 software packages were adopted in these papers, with many-facet…

Attachment difficulties are associated with a range of adverse outcomes in mental health, and people with intellectual disabilities (IDs) may be at greater risk of experiencing difficulties in their attachment relationships. This review critically evaluated recent research measuring the prevalence of attachment difficulties in people with ID.…

Clinical Question: Among school-age children who speak AAE (P), does the use of dialect scoring modifications (I), when compared to traditional scoring methods (C), yield more reliable identification of true language disorders (O)? Method: Structured Review. Study Sources: Google Scholar and ASHAWire. Search Terms: (1) "dialect" OR…

Quantitative information about test score reliability can be presented in terms of the distribution of equated scores on an alternate form of the test for test takers with a given score on the form taken. In this paper, we describe a procedure for estimating that distribution, for any specified score on the test form taken, by estimating the joint…

Structural equation modeling (SEM) is one of the most popular multivariate statistical techniques in Turkish educational research. This study elaborates the SEM procedures employed by 75 educational research articles which were published from 2010 to 2015 in Turkey. After documenting and coding 75 academic papers, categorical frequencies and…

When classifying the evidence base of practices, special education scholars typically appraise study quality to identify and exclude from consideration in their reviews unacceptable-quality studies that are likely biased and might bias review findings if included. However, study quality appraisals used in the process of identifying evidence-based…

The ability to reason scientifically and communicate research appropriately is central to psychological literacy. Scientific research has little value unless scientists are able to convey results and their consequences clearly to others. In this study, we outline a method of assessing the development of psychological literacy in undergraduate…

This paper was produced as an added resource for the report "Outcomes from the Productivity Places Program 2009." "Outcomes from the Productivity Places Program 2009" presents information about the outcomes of students who completed their vocational education and training (VET) under the Productivity Places Program (PPP)…

The purpose of this study was to present an empirical correction of the KR21 (Kuder Richardson test reliability) formula that not only yields a closer approximation to the numerical value of the KR20 without overestimation, but also simplifies computation. This correction was accomplished by introducing several correction factors to the numerator…

Summarizes the principles of instrument validity and reliability and identifies deviations from these principles in a random sample of 55 research studies published in 1989 in 5 refereed nursing journals targeted toward practicing clinicians. Provides documentation, justification, and suggestions for nursing educators, journal editors, and…

Rasch and classical test analysis methods were compared with respect to their similarities and differences in the identification of noninformative items and implausible person records. Using computer simulated data with known parameters, each model was evaluated in terms of its effectiveness in: (1) identifying noninformative or "bad"…

The Alpha Omega Completed Sentence Form (AOCSF) was developed to identify and measure a person's adaptational approaches to information concerning their own death or the possible death of a significant other. In contrast to the Kubler-Ross stage theory, the adaptational approach recognizes a person's capacity to assimilate new information which…

Using the constructs of Rogers, Ellis, and Barrett-Lennard, a twenty-five item Likert-type instrument, the Non-Directive Supervisory Behavior Scale, was developed to measure directive vs. non-directive supervisory behavior. One hundred ninety-five in-service teachers, randomly selected from two school districts, completed the twenty-five item…
