This study aims to develop a valid and reliable measuring instrument that can measure the level of mathematical language used by students and their teachers during the teaching of fractions to fourth-grade primary school students. This study is a methodological validity and reliability study. In total, 999 students from fourteen different…

The aim of this study was to develop a Likert type attitude scale for high school students with regard to high school physics lessons. The research was carried out with high school students who were studying in Ankara. First, the opinions of 105 high school students about physics lessons were obtained and then 55 scale items were determined from…

Qualitative research conducted through occupational socialization theory has documented that physical educators feel marginalized and isolated in schools. We sought to propose and provide initial evidence of validity and reliability for the Physical Education Marginalization and Isolation Survey (PE-MAIS). Physical educators (n = 420) completed an…

The first aim of this study was to develop a computer adaptive EFL test (CALT) that assesses test takers' listening and reading proficiency in English with dichotomous items and polytomous testlets. We reported in detail on the development of the CALT, including item banking, determination of suitable item response theory (IRT) models for item…

The Social Skills Rating System (SSRS) developed by Gresham and Elliott (1990) is a multirater, norm-referenced instrument measuring social skills and adaptive behavior in preschool children. The aims of the present study were (a) to test the factorial structure of the Parent Form of the SSRS for the first time with a German preschool sample (391…

Richard Christie's description of the Machiavellian personality orientation highlights the behaviors of those individuals who are highly successful manipulators of others. Scanning some Machiavellian works for items to tap…

A Monte Carlo investigation of simplex fitting as a method of determining the dimensionality of binary data matrices was conducted. Examination of the fit of correlation matrices with a known factor structure to correlation matrices that represent the perfect simplex shows that simplex fitting is a feasible approach under some circumstances. (SLD)

People's beliefs about the origins of their health, sometimes referred to as health locus of control, have been shown to influence a variety of important behaviors, including the propensity to engage in effective health maintenance activities, and the willingness to seek and follow medical advice.

A live tailored achievement testing study was conducted to compare procedures based on the one- and three-parameter logistic models. Previous studies yielded inconclusive results because of the procedures by which item calibrations were linked and because of the item selection procedures. Using improved procedures, 83 college students were tested…
