Four-parameter models have received increasing psychometric attention in recent years, as a reduced upper asymptote for item characteristic curves can be appealing for measurement applications such as adaptive testing and person-fit assessment. However, applications can be challenging due to the large number of parameters in the model. In this…

Lee, Silvia Wen-Yu – International Journal of Science and Mathematics Education, 2018
The purpose of this study was, first, to understand the item hierarchy regarding students' understanding of scientific models and modeling (USM). Secondly, this study investigated Taiwanese students' USM progression from 7th to 12th grade, and after participating in a model-based curriculum. The questionnaire items were developed based on 6…

Schiffl, Iris – Universal Journal of Educational Research, 2016
Science standards have been a topic in educational research in Austria for about ten years now. Starting in 2005, competency structure models have been developed for junior and senior classes of different school types. After evaluating these models, prototypic tasks were created to point out the meaning of the models to teachers. At the moment,…

Sung, Pei-Ju; Lin, Su-Wei; Hung, Pi-Hsia – Universal Journal of Educational Research, 2015
Task difficulty is a critical issue affecting test developers. Controlling or balancing the item difficulty of an assessment improves its validity and discrimination. Test developers construct tests from the cognitive perspective, by making the test constructing process more scientific and efficient; thus, the scores obtained more precisely…

Hall-Mills, Shannon; Apel, Kenn – Communication Disorders Quarterly, 2013
We evaluated the narrative and expository writing samples of 12 adolescents with language-learning disabilities (LLD) in Grades 6 to 12 for elements of microstructure (e.g., productivity, grammatical complexity) and macrostructure (genre-specific text structure elements) using an experimental measure. Writing samples were elicited with…

Wang, Jianjun – School Science and Mathematics, 2011
As the largest international study ever taken in history, the Trend in Mathematics and Science Study (TIMSS) has been held as a benchmark to measure U.S. student performance in the global context. In-depth analyses of the TIMSS project are conducted in this study to examine key issues of the comparative investigation: (1) item flaws in mathematics…

Liu, Xiufeng; Lesniak, Kathleen M. – Science Education, 2005
Using the US national sample from the Third International Mathematics and Science Study (TIMSS) and the Rasch modeling method, this study identified the conceptual progression sequence of various matter concept aspects, and compared students' latent abilities against the sequence. We found that the four matter aspects, i.e. conservation, physical…
