Divergent thinking (DT) ability is widely regarded as a central cognitive capacity underlying creativity, but its assessment is challenged by the fact that DT tasks yield a variable number of responses. Various approaches for the scoring of DT tasks have been proposed, which differ in how responses are evaluated and aggregated within a task. The…

This study investigated the impact of language sample length on mean length of utterance (MLU) and aimed to determine the minimum number of utterances required for a reliable MLU. Conversations were collected from Mandarin-speaking, hard-of-hearing and typical-hearing children aged 16-81 months. The MLUs were calculated using sample sizes ranging…

When describing motion in physics, the selection of a frame of reference is crucial. The graph of a moving object can look quite different based on the frame of reference. In recent years, various tests have been developed to assess the interpretation of kinematic graphs, but none of these tests have specifically addressed differences in reference…

The intricate relationship between representational competence and content knowledge in organic chemistry has been widely debated, and the ways in which representations contribute to task difficulty, particularly in assessment, remain unclear. This paper presents a multiple-choice test instrument for assessing individuals' knowledge of fundamental…

The current study uses the Rasch Model to measure lower-secondary school students' critical thinking skills on photosynthesis topics. Critical thinking skills are considered essential in science education, but few valid and practical measurement instruments remain. The current study fills the gap by adapting the instrument from the Watson-Glaser…

Although self-assessment in critical thinking is thought to help students recognise their strengths and weaknesses, the reliability and validity of the assessment tool is still questionable, so a more objective evaluation is needed. Objective of this investigation is to assess the self-assessment tools in evaluating students' critical thinking…

This study aims to evaluate the quality of English reading comprehension test instruments used in informal learning, especially as English literacy tests. With a quantitative approach, the analysis was carried out using the Rasch model through the Quest program on 30 multiple-choice questions given to 30 grade IX students from informal educational…

The current paper intends to exploit the Many Facet Rasch Model to investigate and compare the impact of situations (items) and raters on test takers' performance on the Written Discourse Completion Test (WDCT) and Discourse Self-Assessment Tests (DSAT). In this study, the participants were 110 English as a Foreign Language (EFL) students at…

Tools to measure autism knowledge are needed to assess levels of understanding within particular groups of people and to evaluate whether awareness-raising campaigns or interventions lead to improvements in understanding. Several such measures are in circulation, but, to our knowledge, there are no psychometrically-validated questionnaires that…

This study aimed to develop a standardised instrument for diagnosing science misconceptions in primary school children. Following a developmental research approach using the 4-D model (Define, Design, Develop, Disseminate), 100 four-tier multiple choice items were constructed. Content validity was established through expert evaluation by six…

This study investigates children's vocabulary knowledge in Finnish Sign Language (FinSL), specifically their understanding of different form-meaning mappings by using a multilayered assessment format originally developed for British Sign Language (BSL). The web-based BSL vocabulary test by Mann (2009) was adapted for FinSL following the steps…

This study aims to compare the G and Phi coefficients as estimated by D studies for a measurement tool with the G and Phi coefficients obtained from real cases in which items of differing difficulty levels were added and also to determine the conditions under which the D studies estimated reliability coefficients closer to reality. The study group…

In this study, it was aimed to develop an achievement test taking into account the subject acquisitions of the sound and properties unit in the sixth-grade science course. In the test development phase, firstly, literature review for the study was conducted. Then, 30 multiple choice questions in align with the subject acquisition in the 2018…

The purpose of this study was to investigate the validity of the vocabulary subsection of a high-stakes university entrance exam for Ph.D. programs using the argument-based approach. All the three different versions of the test administered in a period of five years and the responses of 12,500 test-takers were studied. The study focused on four…

This study verified validity and reliability of the School Function Assessment (SFA) using Rasch analysis in South Korean school-based occupational therapy sites serving children with intellectual disabilities and others. Participants were 103 elementary school children (grades 1 through 6) with disabilities. Rasch analysis revealed several…
