Polar coordinate analysis is a powerful data reduction technique based on the Zsum statistic, which is calculated from adjusted residuals obtained by lag sequential analysis. Its use has been greatly simplified since the addition of a module in the free software program HOISAN for performing the necessary computations and producing…

The measurement error in principal components extracted from a set of fallible measures is discussed and evaluated. It is shown that as long as one or more measures in a given set of observed variables contains error of measurement, so also does any principal component obtained from the set. The error variance in any principal component is shown…

This research examines the effects of nonattending response pattern contamination and select response style patterns on measures of model fit (CFI) and internal reliability (Cronbach's [alpha]). A simulation study examines the effects resulting from percentage of contamination, number of manifest items measured and sample size. Initial results…

The development and deployment of STEM education in every continent and country are different. An instrument to access the current situation of the application, knowledge, as well as attitude towards STEM education, is necessary. This research aimed to design and develop a valid instrument that can be used to assure the quantitative degree of…

The aim of this study is to develop and validate the School's Emotional Climate scale. To this end, 683 teachers working in elementary and middle schools were recruited. An item pool with 39 items was created based on an extensive literature review and expert opinions. The items were reviewed by experts and seven items were dropped out from the…

Considerable past classroom learning environment research has focused on the primary and secondary levels of education and the subject areas of science and mathematics. The current study is distinctive in its focus on university business statistics learning environments. For the first time, we validated and applied the widely-used What Is…

This study investigated the psychometric properties of the Chinese version of the STEM Career Interest Survey (STEM-CCIS) with data from 590 high-school students in Taiwan. Measurement models based on Social-Cognitive Career Theory (SCCT) and STEM discipline-specific dimensions (Science, Technology, Engineering, Mathematics) were examined using…

To assess the strength of conceptual understanding of number sense, a three-tier number sense test (TTNST) for fifth-grade students was developed and validated in this study. The three-tier test includes a content tier that assesses content knowledge of number sense, a reason tier that assesses a reason given for selecting a first-tier response,…

Purpose: The significance of visuo-semiotic models in biology education has increased. Students have to develop visuo-semiotic skills, which could enable them to learn biology effectively. However, a lack of a universal theory of visual literacy has made it challenging to develop and assess visualization skills, including visuo-semiotic skills.…

The ability to model and apply technology standards has been outlined by the Council for the Accreditation of Educator Preparation (CAEP) as a vital skill for teacher candidates to possess before they enter the field. It follows that teacher preparation programs must prepare their teacher educators to address the necessary skills and knowledge…

The aim of this study was to develop a valid and reliable assessment and evaluation instrument to specify the efficacy of the students in technology and design courses. The assessment instrument was composed of an item pool, experts' views about the validity scope, pre-application, analysis of structure validity and reliability analysis steps.…

The satisfaction of adolescents' perceived psychological needs facilitates their academic achievement and adjustment within school. A first step in this direction is the identification of adolescents' psychological needs and the environmental factors to meet these needs. Based on the theory of Existence, Relatedness, and Growth, known as ERG, the…

For decades, researchers have attempted to define and measure what motivates individuals to achieve. Numerous attempts have sought to measure achievement motivation by using self-report tests. The concepts of motivation and achievement motivation have a rich history of being discussed among different cultures. The purpose of this study was to…

The purpose of the study is to analyze gifted and talented students' project performances and views about them. In the study, explanatory sequential design, which is one of the mixed method research designs, was applied. In the quantitative phase of the study, project performances of the students were identified, while, in the qualitative phase,…

This study provides the development phases and initial psychometric evaluation of the Integrated Care Competency Scale (ICCS) with sample (n = 243). Specifically, quantitative methods with graduate counseling students were used in this study. The ICCS through a three-phase study process was honed to 65 items and broadly assesses graduate…
