The aim of this study is to adapt the scale of the factors affecting argumentation instruction into Turkish. A total of 143 preservice science teachers studying in two different universities located in the east and west of Turkey participated in this study. In the process of adaptation firstly, structure, method and item biases were eliminated.…

The purposes of this study are twofold. First, to investigate the construct or factorial structure of a set of Reading and Mathematics computerized adaptive tests (CAT), "Measures of Academic Progress" (MAP), given in different states at different grades and academic terms. The second purpose is to investigate the invariance of test…

The purpose of this study is twofold: (1) to initialize a new conceptualization of positive feature based Friendship Quality (FQUA) scale on the basis of four dimensions: Closeness, Help, Acceptance, and Safety; and (2) to develop and validate FQUA scale in the form of reflective measurement model. The scale development and validation procedures…

This introduction to confirmatory factor analysis presents an overview of its basic concepts and processes. Conventional factor analysis can be described as set of analytic techniques designed to examine the covariance structure of a set of variables and to provide an explanation of the relationships among those variables in terms of a smaller…

Many researchers acknowledge the prominent role that factor analysis can play in efforts to establish construct validity. Data can be analyzed with no preconceived ideas about the underlying constructs of structure of the data. This approach is exploratory factor analysis, Another approach is used when the researcher has an understanding of the…

The twofold purpose of this study was to investigate the reliability and construct validity of scores on the Japanese version of an academic self-concept scale titled the Dimensions of Self-Concept (DOSC) Form H and ascertain any relationships between scores on the DOSC scale and selected demographic variables, including class, gender, and…

Factor analysis has historically been used for myriad purposes in the social and behavioral sciences, but an especially important application of this technique has been to evaluate construct validity. Since in the present milieu both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) are readily available to the researcher,…

This follow up study is in response to Miller, Fleming, and Brown-Andersons (1998) study of ethnic differences between Caucasians and African-Americans where the authors suggested that the Spiritual Well-Being (SWB) Scale may need to be interpreted differently depending on ethnicity. In this study, confirmatory factor analyses were conducted for…

Applied factor analysis to the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) scores for 505 gifted students, to evaluate the construct validity of the WISC-III with this population. Results are consistent with the hypothesis that subtests that emphasize speed of reading are not valid for gifted children and suggest that an…

Although the Wechsler Intelligence Scale for Children-Revised (WISC-R) is being rapidly replaced by the third edition of the WISC, questions concerning the construct validity of the WISC-R have not yet been resolved, including the number of factors it measures and whether the same constructs fit across all age levels. This study sought to…

One of the valued objectives of education is the enhancement of a positive self-concept, which itself is a mediating variable of other desired outcomes. To facilitate the assessment of this goal, reliable and valid scores on self-concept scales are required for the proper interpretation of related substantive issues. The main purpose of this study…

The purpose of this study was to translate and validate an Arabic version of the Learning Transfer System Inventory (LTSI) for use in Jordan. The LTSI was administered to 450 employees employed by public and private sector organizations operating in Jordan. Principle axis factoring with oblique rotation was used to uncover the underlying structure…

A mental model is a knowledge structure composed of concepts and the relations between them. Mental models are distinct from declarative and procedural knowledge--they go beyond semantic relationships and skills acquisition and contain varied intellectual skills and knowledge. This study describes an initial investigation into the construct…

In the early 1970s A. Constantinople wrote a seminal article that led to the development of the construct of psychological androgyny. The Bem Sex-Role Inventory is a popular measure of the construct, but the measure remains controversial. The construct validity of scores from the measure was explored using confirmatory factor analysis on data from…

This study evaluated the construct validity of the Wechsler Intelligence Scale for Children, Third Edition (WISC-III) with children (ages 8 to 13) having learning disabilities who were either Hispanic (N=120) or Non-Hispanic white (N=120). Factor analyses found that the WISC III has a three factor structure consisting of verbal comprehension,…
