Numerous studies have been published about instruments intended to quantitatively measure students' epistemic beliefs about science; however, as this researcher would discover, developing an instrument to accurately measure epistemic beliefs about physics knowledge is not always as straightforward as the literature would make it seem. Given a lack…

Research indicates academic integration and social integration are predictors of doctoral student persistence at any program stage. However, researchers have not defined, operationalized, and measured academic or social integration consistently. Further, no instruments exist that measure academic and social integration of doctoral students in…

The purpose of this study is to present a review of instruments developed to measure perceptions of special educators regarding their competencies and to provide a synthesis of research studies using these measurement instruments. A total of 29 studies were included in this review, and 20 instruments were used across the studies. The results were…

Mixture Rasch (MixRasch) models conventionally assume normal distributions for latent ability. Previous research has shown that the assumption of normality is often unmet in educational and psychological measurement. When normality is assumed, asymmetry in the actual latent ability distribution has been shown to result in extraction of spurious…

The purpose of this study is to develop a valid and reliable scale to measure the team perception levels of choir members. In the first step, a draft scale comprising 54-items was administered to 332 choir members. With the KMO (Kaiser-Meyer-Olkin) test for sampling adequacy, KMO value was found to be 0.936. Factor analysis on the scale items…

Purpose: This study aimed to compare the performance of latent class differential item functioning (DIF) approach and IRT based DIF methods using manifest grouping. With this study, it was thought to draw attention to carry out latent class DIF studies in Turkey. The purpose of this study was to examine DIF in PISA 2015 science data set. Research…

In this study, it was aimed to develop a valid and reliable scale to determine the teaching styles of teachers. The final scale composed of 44 items were applied to the 605 teachers with various branches. Participants are teachers who are working in private and public schools in the province of Hatay. This study is one of the types of quantitative…

In view of the ubiquitous increase in the use of C-tests, which are almost unanimously believed to measure general language proficiency, this study investigates whether the aspects of language proficiency tapped into by the C-test format are the same when the test is taken by a learner population other than that of foreign language learners.…

More than three decades after their introduction, diagnostic classification models (DCM) do not seem to have been implemented in educational systems for the purposes they were devised. Most DCM research is either methodological for model development and refinement or retrofitting to existing nondiagnostic tests and, in the latter case, basically…

The item responses of examinees who rapid-guess, who do not spend enough time reading and engaging with an item, will not reflect their true ability on that item. Rapid-disengagement refers to rapidly selecting a response to multiple-choice items (i.e., rapid-guess), omitting items, or providing short-unrelated answers to open-ended items in an…

Background: The self-concept of children has an impact on later behavioural development and psychopathology; therefore, evidence of the accurate measurement of self-concept is important. Harter and Pike's (1984, "Child Development," 55, 1969) commonly used measure of self-concept, the Pictorial Scale of Perceived Competence and Social…

The purpose of this report is to provide a synthesis of the research on K-12 testing accommodations. In this report, we summarize the research published in 2017. Previous reports by NCEO have covered research published since 1999. During 2017, 14 research studies were published on the topic of testing accommodations in the elementary and secondary…

The present study leveraged advances in automated essay scoring (AES) technology to explore a proof of concept for a writing screener using the "Project Essay Grade" (PEG) program. First, the study investigated the extent to which an AES-scored multi-prompt writing screener accurately classified students as at risk of failing a Common…

Critical Thinking is a generally recognized educational ideal at all levels of the educational process. This study validated the critical thinking test on Slovak conditions. Data were collected from 50 respondents studying at university. Bachelor's and Master's students from all grades, aged 21 to 36 (x = 23.00; SD = 2.84) were represented. Model…

This article analyses research of theories and models of intelligence. It examines current developments in intelligence research, covering the formation of more complex and diverse intelligence theories. First, the article examines some of the widely used aptitude/intelligence tests include, such Stanford-Binet Intelligence Quotient, Wechsler…
