In scientific research on creativity, there has been considerable debate concerning the criteria by which a production can be judged more or less creative, that is, about the definition of "creativity." The most frequent definition -- the "standard" definition -- incorporates the criteria of "novelty" and…

The main aim of this study was to (a) test the construct validity of complex problem solving (CPS); (b) examine the ability to acquire knowledge as a mediator of the relationship between intelligence and CPS performance; and (c) investigate the personal need for structure as a moderator of the relationship between intelligence and knowledge…

This study developed and tested a Turkish translation of the 23-item Sahin-Francis Scale of Attitude toward Islam (containing six negatively-voiced items) on data provided by 493 participants (191 school students and 302 undergraduate students). Two research questions were tested on these data. First, exploratory factor analyses suggested that…

The aim of the study is to develop a Likert-type scale to determine the play preferences of children attending pre-school education. The research was designed and carried out according to the survey research model. Data collected from 3 different study groups were used in the scale development process. The study groups consist of parents of…

The efficiency of cognitive component skills is typically assessed with speeded performance tests. Interpreting only effective ability or effective speed as efficiency may be challenging because of the within-person dependency between both variables (speed-ability tradeoff, SAT). The present study measures efficiency as effective ability…

In the United States, science education has experienced substantial shifts in the last decade. For in-service teachers, professional development programs (PDPs) play an important role in reform success. Despite well-known core features of effective PDPs, research still suggests a range of results among programs that claim to use those features. An…

Pragmatics refers to the ability to effectively use and interpret language in different contexts. Pragmatic abilities develop and refine through childhood, and they are essential for socialization, academic achievement and wellbeing. The scarcity of assessment tools in this field makes it challenging to provide a comprehensive assessment of…

Background and Context: As computer science (CS) education expands and the need for well-prepared CS teachers grows, understanding what motivates teachers to teach CS can help address challenges to recruiting, preparing, and retaining teachers. Objective: The goal of this work was to develop and validate a scale that measures teachers' motivation…

Assessment literacy is an essential competency area for professional counselors who administer tests and interpret the results of participants' scores. Using factor analysis to demonstrate internal structure validity of test scores is a key element of assessment literacy. The underuse of psychometrically sound instrumentation in professional…

This study examined the construct validity of the Autism Classification System of Functioning: Social Communication (ACSF). Participants included 145 parents of children with autism (2-19 years). The degree of convergent and discriminant validity between parent reported ACSF and subscales from Social Responsiveness Scale 2nd edition and Behavior…

Virtual reality (VR) simulation training for helicopter search and rescues (SAR) hoist operators is very uncommon in comparison to the availability of pilot simulation training. SAR hoist operators control winch systems for hoisting objects or people during helicopter flight. Using a rear crew helicopter VR training simulator we sought to quantify…

The aim of this study is to examine how the practice of different item removal strategies during exploratory factor analysis (EFA) phase of scale development change the number of factors, factor loadings, explained variance ratio, and reliability values (a and ?) explained. In the study, data obtained from 379 university students were used for the…

Conceptual replications have received increased coverage in the educational research agenda. This article argues for clarity in, and justification of, the definition, scope, and boundaries of a conceptual replication and what it can and cannot do. It argues for clear justifications when changing components from those of the original study. The…

It is necessary to supply proof regarding the construct validity of the scales. Especially, when new scales are developed the construct validity is researched by the Exploratory Factor Analysis (EFA). Generally, factor extraction is performed via the Principal Component Analysis (PCA) which is not exactly factor analysis and the Principal Axis…

This study provided validity evidence of the Questionnaire of English Writing Self-Efficacy (QEWSE) based on the five sources of validity evidence described in the "Standards for Educational and Psychological Testing" (AERA, APA, & NCME, 2014). Items of this measure demonstrated close alignment with the linguistic domain and the…
