Progressing from additive to multiplicative thinking is a key outcome of school mathematics, making ratios an essential topic of study in junior secondary. In this study, 15 Australian Year 8 students were administered a ratio test followed by semi-structured interviews to explore their conceptions of ratio prior to formal instruction. In this…

In recent years, some models for binary and graded format responses have been proposed to assess unipolar variables or "quasi-traits." These studies have mainly focused on clinical variables that have traditionally been treated as bipolar traits. In the present study, we have made a proposal for unipolar traits measured with continuous…

A Monte Carlo simulation study was conducted to compare fit indices used for detecting the correct latent class in three dichotomous mixture item response theory (IRT) models. Ten indices were considered: Akaike's information criterion (AIC), the corrected AIC (AICc), Bayesian information criterion (BIC), consistent AIC (CAIC), Draper's…

Research has suggested that changing one's answer on multiple-choice examinations is more likely to lead to positive academic outcomes. This study aimed to further understand the relationship between changing answer selections and item attributes, student performance, and time within a population of 158 first-year medical students enrolled in a…

This study investigated the application of item quadruplets to control social desirability in measuring socio-emotional competencies and their relationship with intelligence. Quadruplets involve four variations of an item, differing in the polarity of their descriptive content and evaluative content (social desirability): positive-desirable,…

A new index of item discrimination power (IDP), dimension-corrected Somers' D (D2) is proposed. Somers' D is one of the superior alternatives for item-total- (Rit) and item-rest correlation (Rir) in reflecting the real IDP with items with scales 0/1 and 0/1/2, that is, up to three categories. D also reaches the extreme value +1 and -1 correctly…

Knowledge tracing (KT), the task of tracking the knowledge state of each student over time, has been assessed actively by artificial intelligence researchers. Recent reports have described that Deep-IRT, which combines Item Response Theory (IRT) with a deep learning model, provides superior performance. It can express the abilities of each student…

Psychometricians at an organization named the Education and Training Evaluation Commission (ETEC) developed a new test scoring method called the latent D-scoring method (DSM-L) where it is believed that the new method itself is much easier and more efficient to use compared to the Item Response Theory (IRT) method. However, there are no studies…

The content validity ratio (CVR), which is suggested by Lawshe (1975), is a widely used index to quantify content validity. In this study, the Bayesian approach is used to determine the minimum number of experts required to agree an item is essential, and then the CVR is calculated.

This study aimed to propose a new method for scoring C-Tests as measures of general language proficiency. In this approach, the unit of analysis is sentences rather than gaps or passages. That is, the gaps correctly reformulated in each sentence were aggregated as sentence score, and then each sentence was entered into the analysis as a polytomous…

The cardinal virtues (prudence, justice, fortitude, and temperance) have relevance within the areas of character education and integral or comprehensive formation. In recent years, there has been growing interest and a great deal of literature produced on character education and its measurement. In this paper, we propose a questionnaire (a…

This study aimed to reveal the differences in individuals' abilities, their standard errors, and the psychometric properties of the test according to the two methods of applying the test (electronic and paper). The descriptive approach was used to achieve the study's objectives. The study sample consisted of 74 male and female students at the…

Background and Context: Educators and researchers are interested in building the computational thinking (CT) skills of K-12 students. However, the availability of language-agnostic assessments for lower elementary graders remains limited. Objective: We present preliminary insights into the reliability and validity of the Computational Thinking…

Although examining teachers' various areas of knowledge in classroom practices has attracted considerable attention during recent decade, a short multidimensional questionnaire to assess the interactions of the knowledge domains with teachers' technological knowledge is unavailable in the literature. Thus, this research presents a self-assessment…

This article presents an updated meta-analysis of survey experiments comparing the performance of the item count technique (ICT) and the direct questioning method. After synthesizing 246 effect sizes from 54 studies, we find that the probability that a sensitive item will be selected is 0.089 higher when using ICT compared to direct questioning.…
