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 aim of this study is to adapt the Generalized Expectancy for Success Scale, which was developed by Fibel and Hale (1978) and revised by Hale et al. (1992) into Turkish in terms of adaptation, reliability and adaptation. This study modelled by survey is a scale adaptation study. The scale was adapted into Turkish culture in terms of language…

Short forms of psychometric scales have been commonly used in educational and psychological research to reduce the burden of test administration. However, it is challenging to select items for a short form that preserve the validity and reliability of the scores of the original scale. This paper presents and evaluates multiple automated methods…

There are many ways to assess creativity. The most commonly used measures of creativity include divergent thinking tests and a variety of self-report instruments. In the meantime, teacher rating has been playing an increasingly important role in selecting creative students. However, the relationships among various creativity assessment approaches…

The aim of this article is to report the validity and reliability of Teacher Leadership Inventory (TLI). The sample of the study consists of 244 trained teachers who are chosen using random sampling technique from 19 secondary schools in Perak. The content validity, criterion validity and construct validity analyses have been carried out by using…

In this study, it is aimed to adapt the Scientific Reasoning Scale (SRS) into Turkish. The translated form has been provided to the students enrolled at different levels together with a form in which they were requested to present what they have understood and the reason of their responses. It was seen that the explanations of students to one item…

Statement of Problem: Although there is a rapidly increasing interest in creativity in specific domains such as science and math, there are not enough valid and reliable scales to assess students' creativity in these domains. If mathematical creativity potential can be measured, then the curriculum can be adapted to address the needs of creative…

This research study was designed to establish the reliability of the Teenage Nonviolence Test (TNT). The consistency and factor structure of the TNT using a sample of 376 adolescents were evaluated. The stability of the TNT was assessed over time by administering the TNT twice with a two week intervening interval to 87 adolescents. The TNT appears…

A study examined the extent to which a 19-item short form of the Speech Evaluation Instrument (SEI) is a reliable instrument, what factor structure emerges from the analysis, and how that factor structure compares to that reported for the 30-item long form of the SEI. Subjects, 606 undergraduates enrolled in speech communications classes at two…

This paper reports on the development and refinement of the Connecticut School Effectiveness Questionnaire (CSEQ) and the Connecticut School Effectiveness Interview (CSEI), the primary data collection tools used in the Connecticut State Department of Education School Effectiveness Project. The primary purpose of both the CSEI and the CSEQ is to…

The initial form of the Coping with Death Scale consisted of 30 items designed to obtain responses arranged along a seven-point Likert-type scale. Each item on the scale was derived from personal responses of students who completed a death and dying seminar. The items appeared to fall into two categories: coping with self and coping with others.…

Factor analysis can be a valuable tool for assessing validity; however, the reliabilities of identified factors must be attended to. This study examined the impacts of item variance on factor stability and structure. The attempt was to determine empirically whether unnumbered graphic scales scored using a larger number of scale steps produce more…

Confirmatory maximum likelihood estimation of measurement models was used to evaluate the construct generality of self-report measures of anxiety across male and female samples. These measures included Spielberger's State-Trait Anxiety Inventory, Taylor's Manifest Anxiety Scale, and two forms of Endler, Hunt and Rosenstein's S-R Inventory of…

Provides psychometric information on the second edition of the Beck Depression Inventory (BDI-II) (A. Beck, R. Steer, and G. Brown, 1996) for internal consistency, factorial validity, and gender differences. Results indicate that the BDI-II is a stronger instrument than its predecessor in terms of factor structure. (SLD)

The reliability and validity of the State-Trait Anxiety Inventory for Children (STAIC) was studied with 675 adolescents aged 12 to 18 recruited from clinical and community sources. The STAIC is a self-report measure that has been widely used to assess state and trait anxiety of children. It has been suggested that the child version may be more…
