The Investigators studied scoring reliability of Candidates' ten day unit plans of instruction through prescribed action research projects, across three academic years. Scoring of the projects in year one provided opportunities for further refinement of the action research evaluation methods in year two. Across three terms in years one and two…

The primary aim of this study was to evaluate the reliability of the University's Masters' level (M-level) generic assessment criteria when used by lecturers from different disciplines. A further aim was to evaluate if subject-specific knowledge was essential to marking these dissertations. Four senior lecturers from diverse disciplines…

A meta-analysis of the reliability of the scores from a specific test, also called reliability generalization, allows the quantitative synthesis of its properties from a set of studies. It is usually assumed that part of the variation in the reliability coefficients is due to some unknown and implicit mechanism that restricts and biases the…

During in-training assessment students are frequently assessed over a longer period of time and therefore it can be expected that their performance will improve. We studied whether there really is a measurable performance improvement when students are assessed over an extended period of time and how this improvement affects the reliability of the…

In this research, the classical test theory and generalizability theory analyses were carried out with the data obtained by a job performance scale for the years 2005 and 2006. The reliability coefficients obtained (estimated) from the classical test theory and generalizability theory analyses were compared. In classical test theory, test retest…

Purpose: The vowel space area (VSA) has been used as an acoustic metric of dysarthric speech, but with varying degrees of success. In this study, the authors aimed to test an alternative metric to the VSA--the "formant centralization ratio" (FCR), which is hypothesized to more effectively differentiate dysarthric from healthy speech and register…

In higher order factor models, general intelligence (g) is often found to correlate perfectly with lower-order common factors, suggesting that g and some well-defined cognitive ability, such as working memory, may be identical. However, the results of studies that addressed the equivalence of g and lower-order factors are inconsistent. We suggest…

Three experiments examined children's (N = 80; 40; 48) sensitivity to error magnitude as a measure of informants' past accuracy, and indication of future reliability. Experiments 1 and 2 assessed whether, in a forced-choice task, children would evaluate as better and show greater trust in an informant whose previous errors were consistently within…

In this article, procedures are described for estimating single-administration classification consistency and accuracy indices for complex assessments using item response theory (IRT). This IRT approach was applied to real test data comprising dichotomous and polytomous items. Several different IRT model combinations were considered. Comparisons…

This paper aimed at examining the learning strategies constructs and to investigate the relationship between learning strategies and motivation in Arabic courses. The study uses a questionnaire as the information-gathering instrument, and the participants comprised students from two public universities in Peninsular Malaysia who are studying…

Graduate assistants have an impact on undergraduate education through course instruction. For preservice agricultural education teachers, experiences with teaching assistants may be particularly influential, as their observations of educators could impact their perceptions and beliefs toward teaching. This qualitative study utilized data collected…

The study investigated the effect of demonstration method of teaching on students' achievement in agricultural science in secondary school in Kogi East Education Zone of Kogi State. Two research questions and one hypothesis guided the study. The study employed a quasi-experimental research design. The population for the study was 18225 senior…

This piece of article is culled from a larger study. The study investigated the relationship between family-work conflict, Type-E personality and stress in married female Nigerian University Administrators. The study adopted ex-post facto design. The sample consisted of 800 female administrators in the senior cadre of executive/administrative…

How individuals construct narratives involving attachment figures (e.g., parents) should reflect their representation of those individuals as either comforting or unsupportive (Bowlby, 1969). Similarly, how individuals talk about parents' childhood experiences may also reflect their attachment representation. Sixty-five 13- to 16-year-old…

Described herein is the academic lineage and independent validation of the Self-Efficacy Teaching and Knowledge Instrument for Science Teachers-Revised (SETAKIST-R). Data from 334 K-12 science teachers were analyzed using Partial Credit Rasch models. Principal components analysis on the person-item residuals suggest two latent dimensions:…
