Despite the increasing demand for diagnostic information, observed subscores have been often reported to lack adequate psychometric qualities such as reliability, distinctiveness, and validity. Therefore, several statistical techniques based on CTT and IRT frameworks have been proposed to improve the quality of subscores. More recently, DCM has…

The purpose of this study was to investigate developmental music aptitude with a broader sample in order to propose national norms. Research questions were: 1) To what extent are published Primary Measures of Music Aptitude (PMMA) norms different from those established using a current sample? 2) Are there comparative differences in PMMA item…

This work presents a study that used distributed language representations of test items to model test item difficulty. Distributed language representations are low-dimensional numeric representations of written language inspired and generated by artificial neural network architecture. The research begins with a discussion of the importance of item…

Genetics is universally recognized as a core aspect of biological and scientific literacy. Beyond genetics' own role as a major unifying topic within the biological sciences, understanding genetics is essential for understanding other integral ideas such as evolution and development. Genetics understanding also underlies public decision making…

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…

There is a pervasive need for school systems to empirically and reliably assess the data literacy and data use skills of their educators (Ingram et al., 2004). With the federal government holding states and school districts accountable for student achievement and the increased emphasis of high stakes testing in schools, it is also critical to be…

Investigating the psychometric properties of a screening instrument for young children is necessary to ascertain its quality and accuracy. In light of the important role culture plays on human beliefs and parenting styles, a newly translated and adapted test needs to be studied. Evaluating outcomes on a translated version of a test may reveal…

In 1997, based on the amendments to Individuals with Disabilities Education Act (IDEA), all states were faced with a statutory requirement to develop and implement alternate assessments for students with disabilities unable to participate in the statewide large-scale assessment. States were given the challenge of creating, implementing, and…

The Non-Equivalent groups with Anchor Test equating (NEAT) design is a widely used equating design in large scale testing that involves two groups that do not have to be of equal ability. One group P gets form X and a group of items A and the other group Q gets form Y and the same group of items A. One of the most commonly used equating methods in…

Working under classical test theory (CTT) and item response theory (IRT) frameworks, this study investigated psychometric properties of the Revised Purdue Spatial Visualization Tests: Visualization of Rotations (Revised PSVT:R). The original version, the PSVT:R was designed by Guay (1976) to measure spatial visualization ability in…

The Taiwanese early intervention/early childhood special education (EI/ECSE) system is modeled after the federal legislation and practices of the U.S., incorporating specific cultural beliefs in Taiwan. Nonetheless, in EI/ECSE assessments, several challenges are presented, including: (a) limited resources and funding, (b) lack of reliable and…
