This paper presents a systematic literature review characterizing the methodological properties of usability studies conducted on educational and learning technologies in the past 20 years. PRISMA guidelines were followed to identify, select, and review relevant research and report results. Our rigorous review focused on (1) categories of…

Refutation texts, rhetorical tools designed to reduce misconceptions, have garnered attention across four decades and many studies. Yet, the ability of a refutation text to change a learner's mind on a topic needs to be qualified and modulated. In this critical review, we bring attention to sources of constraints often overlooked by refutation…

Correspondence testing to research discrimination in the marketplace has become common and the use of internet applications has allowed researchers to send greater numbers of applications. While questions of research ethics always arise when planning a correspondence test, the issue receives relatively little attention in published correspondence…

The use of standardised tests as a central tool in education policy has in recent decades become a common feature of many national education systems. In 2002 the Israeli Ministry of Education introduced new mandatory state tests for primary and middle schools. The article describes the adoption of these low-stakes tests and assesses their impact…

Exploratory factor analysis (EFA) is a frequently used multivariate analysis technique in statistics. Jennrich and Sampson (1966) solved a significant EFA factor loading matrix rotation problem by deriving the direct Quartimin rotation. Jennrich was also the first to develop standard errors for rotated solutions, although these have still not made…

The paper by Rupp and Templin (2008) is an excellent work on the characteristics and features of cognitive diagnostic models (CDM). In this article, the authors comment on some substantial and methodological aspects of this focus paper. They organize their comments by going through issues associated with the terms "cognitive,"…

Examines several possible difficulties in interpreting the results of studies which employ Piagetian tasks, especially conservation tasks, with older individuals. Notes that Piaget's clinical method allows more flexibility in the assessment of competence than do more quantifiable techniques. Examines the possibility of task misinterpretation by…

THIS STUDY WAS CONCERNED WITH THE NATURE AND RELATIONSHIPS AMONG THE COGNITIVE FACTORS, ANALYSIS AND SYNTHESIS, AND THEIR PERSONALITY AND ACADEMIC CORRELATES. ENTERING FRESHMEN AT THE UNIVERSITY OF MICHIGAN WERE TESTED WITH A BATTERY OF NINE TESTS TO OBTAIN THE DATA REQUIRED FOR ANALYSIS. SUSPECTED CONTAMINATION OF THE TEST RESULTS DUE TO…

Some contemporary trends in social and clinical psychology suggest that individual differences in imaging abilities may become increasingly important. Outlines some of the conceptual and methodological problems that must be clarified if productive research is to be undertaken and reports results of three studies designed to isolate tests which…

Practical advice on frequently asked questions dealing with research and evaluation methodology is presented as rules of thumb, with citations to the author's sources. A statement in the literature is considered a rule of thumb if it meets one of the following criteria: (1) it is specifically called a rule of thumb; (2) it contains numbers in…

THIS ARTICLE OUTLINED THE CURRENT STATUS OF QUANTITATIVE METHODS AND OPERATIONS RESEARCH (OR), SKETCHED THE STRENGTHS OF TRAINING EFFORTS AND ISOLATED WEAKNESSES, AND FORMULATED WORKABLE CRITERIA FOR EVALUATING SUCCESS OF OPERATIONS RESEARCH TRAINING PROGRAMS. A SURVEY OF 105 COMPANIES REVEALED THAT PERT, INVENTORY CONTROL THEORY AND LINEAR…

A suggested technique for analyzing distributions of test scores compares distributions of scores made by groups of pupils on standard tests with distributions made by other groups of students on the same tests. By identifying the percents of student scores which must be shifted to an adjacent cell (interval) to make the two distributions exactly…

The effects of selective dropout and retesting on the assessment of developmental changes in abilities during adolescence are examined. (ST)

Critically reviews an earlier published study that assessed the sensitivity of the cloze procedure to intersentential integration. (AEA)
