This study aimed to develop a reliable and valid scale to reveal the cognitive biases of university students in context of analytical thinking skills. During scale development process, firstly, a 5-point Likert type scale pre-trial form consisting of 60 items was created. The pre-trial form was applied to 450 students in Afyon Kocatepe University.…

The reliability of a test score is usually underestimated and the deflation may be profound, 0.40 - 0.60 units of reliability or 46 - 71%. Eight root sources of the deflation are discussed and quantified by a simulation with 1,440 real-world datasets: (1) errors in the measurement modelling, (2) inefficiency in the estimator of reliability within…

The purpose of this study is to identify which scale short-form development method produces better findings in different factor structures. A simulation study was designed based on this purpose. Three different factor structures and three simulation conditions were selected. As the findings of this simulation study, the model-data fit and…

We analyzed data from the WASI-II manual to determine discrepancy score reliabilities of the Verbal Comprehension (VCI) and Perceptual Reasoning (PRI) indexes and the four subtests in the child and adult standardization samples. Reliabilities of the VCI-PRI discrepancy scores range from 0.78 to 0.86 for children and 0.82 to 0.89 for adults and…

The "consensual assessment technique" (CAT) is a reliable and valid method to measure (product) creativity and often considered "the" gold standard of creativity assessment. The reliability measure traditionally applied in CAT studies--inter-rater reliability--cannot capture time-sampling error, which is a particular relevant…

The purpose of this study was to conduct a conceptual replication of Pendergast et al.'s (2018) study that examined the diagnostic accuracy of a nomogram procedure, also known as a naive Bayesian approach. The specific naive Bayesian approach combined academic and social-emotional and behavioral (SEB) screening data to predict student performance…

This study addresses how Chinese learners of English as a second language (L2) perceive conversations in English materials as compared to speakers of English as a first language (L1). Data were collected through questionnaires completed by 48 participants (28 L2 English learners in China and 20 L1 English speakers in the UK), eliciting evaluations…

The National Assessment of Educational Progress (NAEP) is an integral measure of academic progress over time. It is the largest nationally representative and continuing assessment of what our nation's students know and can do in various subjects such as civics, mathematics, reading, science, technology and engineering literacy, U.S. history, and…

Colleges and universities have become increasingly concerned that requiring standardized test scores for admission is an impediment to campus diversity, and these objections have grown with the recent focus on societal inequities. In addition, the pandemic led to the cancellation of test administrations, which, in turn, caused many institutions to…

In this article, we discuss the development and the administration of a multiple-choice test, which we named "Test of Calculus and Vectors in Mathematics and Physics" (TCV-MP), aimed at comparing students' ability to answer questions on derivatives, integrals, and vectors in a purely mathematical context and in the context of physics.…

The present study aimed to investigate the effects of the EASY Minds program on working memory and selective attention of a group of Iranian students with maths learning disabilities. The study had a quasi-experimental research design with pre-test, post-test, and follow-up tests. Forty students with maths learning disabilities were randomly…

There were 42 Teach for America (TFA) members who had student schedules in both the October 2022 and February 2023 periods. Of those, 33 teachers instructed grades and subjects where students participated in the statewide assessment. The goal of this Research Brief is to estimate the instructional effectiveness of the TFA members in 2022-2023 as…

Coding ability has become an essential digital skill for young children. The graphical programming environment is valuable carrier for cultivating children's coding ability. The purpose of this study is to develop a coding ability test for children, to conduct a graphic coding intervention, and to further explore the impact of multiple factors on…

The rising demand for dual-language immersion (DLI) programs, which offer core instruction in two languages from early grades onward, has raised questions about program design and access. We leverage the rapid expansion of DLI schools across the U.S. state of Utah to estimate effects of DLI program availability on the academic achievement of…

Administrative problems such as computer malfunction and power outage occasionally lead to missing item scores and hence to incomplete data on mastery tests such as the AP and U.S. Medical Licensing examinations. Investigators are often interested in estimating the probabilities of passing of the examinees with incomplete data on mastery tests.…
