At last, a comprehensive guide that meets psychologists and other social scientists' growing need to master the tools of statistical prediction. "Prediction Statistics for Psychological Assessment," by R. Karl Hanson, is the first book to teach students and practitioners the nuts and bolts of prediction statistics, while illustrating the…

A new index of item discrimination power (IDP), dimension-corrected Somers' D (D2) is proposed. Somers' D is one of the superior alternatives for item-total- (Rit) and item-rest correlation (Rir) in reflecting the real IDP with items with scales 0/1 and 0/1/2, that is, up to three categories. D also reaches the extreme value +1 and -1 correctly…

Research Question: This paper examines the overarching question of to what extent different analytic choices may influence the inference about country-specific cross-sectional and trend estimates in international large-scale assessments. We take data from the assessment of PISA mathematics proficiency from the four rounds from 2003 to 2012 as a…

In recent years, the use of data to inform instructional decision making has become a particularly prominent facet of K-12 educators' professional practice. However, research estimates limited opportunities for preservice teachers to learn how to use data, including standardized test data, for such purposes. In response, this article describes the…

Purpose: Computer simulation was used to estimate the statistical properties of searches for maximum word recognition ability (PB max). These involve presenting multiple lists and discarding all scores but that of the 1 list that produced the highest score. The simulations, which model limitations inherent in the precision of word recognition…

Technological literacy defines a competitive vision for technology education. Working together with competitive supremacy, technological literacy shapes the actions of technology educators. Rationalised by the dictates of industry, technological literacy was constructed as a product of the marketplace. There are many models that visualise…

We present a case study of the process through which a methodology was developed and applied to a quasi-experimental research study that employed propensity score matching. Methodological decisions are discussed and summarized, including an explanation of the approaches selected for each step in the study as well as rationales for these…

The general purpose of the present study is to determine the relationship between direct and indirect preference assessments of individuals with severe and multiple disabilities (SMD) and the relationship between the direct preference assessments (single-stimulus, paired-stimulus, and multiple-stimulus) as applied to individuals with SMD, and to…

Exercise physiology courses have transitioned to competency based, forcing Universities to rethink assessment to ensure students are competent to practice. This study built on earlier research to explore rater cognition, capturing factors that contribute to assessor decision making about students' competency. The aims were to determine the source…

Purpose: Graduate admission has become a critical process for quality assurance in tertiary education. Hitherto, most research has investigated the validity of admissions instruments. However, surprisingly little work has been conducted on the overall organization of admission, which often remains "informal, ad hoc, and lacking in…

Diagnostic tools can help schools more consistently and fairly match instructional resources to the needs of their students. To ensure the best educational outcome for each child, diagnostic decision-making systems seek to balance time, clarity, and accuracy. However, recent research notes that many educational decisions tend to be made using…

The purpose of this study is to evaluate the degree to which the Selective Abandonment budget process objectives were achieved by analyzing stakeholder perceptions. Use of this evaluation may enable the district to become more effective, efficient, and more fiscally responsible when developing future program budgeting plans. Program evaluation was…

The aim of this investigation is to assess the correlation among different competencies-assessment systems available on the market to measure social skills in the university environment. In order to carry out the research, three self-perception competency tests were used, and 30 competencies were evaluated in a Likert scale with several response…

This study aimed to develop a valid and reliable measurement tool to enhance ethical evaluation literature. The tool consists of two subscales named "Bases of ethical evaluation," and "Grounds of ethical evaluation." In order to determine the factor structure of the scales, both exploratory and confirmatory factor analyses were…

This study investigated the effect of dynamic Assessment (DA) on the acquisition of L2 grammar by EFL learners. The focus was on teaching Conditional Type II, or Unreal Conditional, which is a difficult structure for language learners to acquire. To this end, two intact classes of intermediate EFL learners, each consisting of 23 male students were…
