This study examined the use of Bayesian analysis methods for the estimation of item parameters in a two-parameter logistic item response theory model. Using simulated data under various design conditions with both informative and non-informative priors, the parameter recovery of Bayesian analysis methods were examined. Overall results showed that…

Research about the development of the graphomotor side of writing is very scarce. The goal of this study was to gain a better understanding of what constitutes graphic complexity of written material by determining the impact of graphic characteristics on handwriting production. In this end, the pen stroke of cursive handwriting was precisely…

In this study Type I Error and the power rates of omega (?) and GBT (generalized binomial test) indices were investigated for several nominal alpha levels and for 40 and 80-item test lengths with 10,000-examinee sample size under several test level restrictions. As a result, Type I error rates of both indices were found to be below the acceptable…

Purpose: Several studies can be found in the literature that investigate the performance of ? under various conditions. However no study for the effects of item difficulty, item discrimination, and ability restrictions on the performance of ? could be found. The current study aims to investigate the performance of ? for the conditions given below.…

The present research explored the awareness that readers have of the difficulty of negative text and aimed to determine whether rereading could impact comprehension and metacomprehension. Participants read passages that sometimes contained negative words such as 'no' and 'not', rated their comprehension, and answered a comprehension question about…

The purpose of this study was to evaluate the effectiveness of linking test scores by using test takers' background data to form pseudo-equivalent groups (PEG) of test takers. Using 4 operational test forms that each included 100 items and were taken by more than 30,000 test takers, we created 2 half-length research forms that had either 20…

Recent studies posit that mental toughness is a relevant construct for predicting achievement outcomes in academic settings. It is a multidimensional construct that encapsulates psychological resources that facilitate consistent performance despite stressors and challenges. However, recent evidence has called into question its multidimensional…

Comprehending a mathematical modelling task is a central prerequisite for the following modelling process. In this study, we investigated the roles that the language proficiency of the students and the linguistic wording of the task play for the comprehension and the successful solving of mathematical modelling tasks. Five mathematical tasks with…

Communication in the 21st century is no longer limited to a mastery of literal level comprehension, although it is an essential element of understanding. Now, more than ever, it is paramount that students are able to read and critically analyze texts in various genres. Coiro, Knobel, Lankshear and Leu (2008) outline the notion of New Literacies as…

In this paper, the probability content in senior secondary mathematics Victorian curriculum between 1978 and 2016 was classified and compared, by content, context, procedural complexity, the SOLO thinking frameworks and use of technology. While probability continues to form an important and increasing component of the curriculum, it has moved from…

In 2013, the Council of Chief State School Officers (CCSSO), working collaboratively with state education agencies, released a set of criteria for states to use to evaluate and procure high-quality assessments. The mathematics section of the document included five content-specific criteria to evaluate alignment of assessments to college- and…

This paper reports the findings of a study that investigated why a large number of test-takers show a low performance in four language skills (listening, speaking, reading, and writing) offered in an entry test used by a College of Technology in Oman to place students in advanced diploma and bachelor's degree programs. The main research question…

This study presents a new approach to synthesizing differential item functioning (DIF) effect size: First, using correlation matrices from each study, we perform a multigroup confirmatory factor analysis (MGCFA) that examines measurement invariance of a test item between two subgroups (i.e., focal and reference groups). Then we synthesize, across…

What motivates high school students to persist with challenging mathematics? The current investigation examined this important question using the concept of mathematics self-schema, that is, students' cognitive generalizations of their selves in learning mathematics. Mathematics self-schemas are important sources of motivation. It was hypothesized…

The impact of the medical curricular reform on anatomy education has been inconclusive. A pervasive perception is that graduates do not possess a sufficient level of anatomical knowledge for safe medical practice; however, the reason is less well-studied. This qualitative study investigated the perceived challenges in learning anatomy, possible…
