Developing mathematics proficiency requires an understanding of mathematics vocabulary. Although previous research has developed several measures of mathematics vocabulary at different grade levels, no study focused solely on fraction vocabularies. We developed and tested a measure of fraction vocabulary for students in Grade 4 to determine the…

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…

The development of assessments as part of the funded LOCUS project is described. The assessments measure students' conceptual understanding of statistics as outlined in the GAISE PreK-12 Framework. Results are reported from a large-scale administration to 3,430 students in grades 6 through 12 in the United States. Items were designed to assess…

Researchers design diagnostic assessments to measure students' knowledge structures and processing skills to provide information about their cognitive attribute. The purpose of this study is to determine the instrument's validity and score reliability, as well as to investigate the use of classical test theory to identify item characteristics. The…

Reading motivation is multidimensional and a critical contributor to students' reading comprehension skill. Its multidimensionality is problematic, as there is currently no consensus on the dimensions underlying reading motivation, which are being tested through a variety of instruments that lack statistical validation. Our goal was to discuss the…

The study determines the conceptual understanding levels of primary school students on the concept of light according to the Rasch Model with a Four-tier Light Conceptual Understanding Test (LCUT). The participants were 355 (164 girls and 191 boys) primary school students studying at a public school in Izmir city center. In the study, the Rasch…

The aim of the study is to develop an achievement test consisting of the questions in verbal intelligence games whose validity and reliability have been ensured and which are in accordance with the learning outcomes of the states of substance and knowing the properties of substance via the five senses taking place in the unit "Let's Know…

This research aimed to investigate animation-based achievement tests according to the item format, psychometric features, students' performance, and gender. The study sample consisted of 52 fifth-grade students in Samsun/Turkey in 2017-2018. Measures of the research were open-ended (OE), animation-based open-ended (AOE), multiple-choice (MC), and…

Assessment of higher-order thinking skills (HOTS) provides few opportunities for students to develop more in-depth knowledge, serving students' ability to identify and solve their problems. One type of instrument for measuring HOTS objectively is the two-tier multiple-choice test (TTMCT). This research is part of the research and development…

This study examined the validity of the Korean version of the Child Behavior Checklist (K-CBCL) with 180 children with autism spectrum disorder (ASD) in South Korea. Rasch analysis was applied to examine item fit, item difficulty, suitability of the response scale, and person and item separation indices of the K-CBCL. The results indicated that,…

Reading comprehension has an important place in lifelong learning. It is an interactive process between the reader and the text. Students need reading comprehension skills at all educational levels and for all school subjects. Determining the level of students' reading comprehension skills is the subject of testing and evaluation. Tests used to…

Critical thinking skills are the 21st-century life skills that are needed by students. However, in elementary schools, there are no instruments that are truly effective and efficient to measure critical thinking skills. This research aims to develop an open-ended question assessment instrument to measure students' critical-thinking skills, to test…

Reasoning about mechanism is central to disciplined inquiry in science and engineering and should thus be one of the foundations of a science, technology, engineering, and mathematics education. In addition, mechanistic reasoning is one of the core competencies listed in the Next Generation Science Standards (NGSS) Engineering Concepts and…

This study is part of a larger design study that iteratively improves a robotics programming curriculum as well as a computational thinking (CT) instrument. Its focus was majorly on CT assessment and particularly on an online CT instrument with logging functionality that can store a student's problem-solving process by recording interactions…

Assessing students' emerging literacy skills is crucial for identifying areas where a child may be falling behind and can lead directly to an increased chance of reading success. The Waterford Assessment of Core Skills (WACS), a computerized adaptive test of early literacy for students in prekindergarten through 2nd grade, addresses this need.…
