This paper presents the adaptation of the POMAS classification of spelling errors (Silliman et al., Developmental Neuropsychology 29:93-123, 2006, Bahr et al., Journal of Speech, Language & Hearing Research 55:1587-1599, 2012; International Journal of Bilingual Education and Bilingualism 18:73-91, 2015) to Polish orthography. We identified the…

It has become increasingly clear that the early use of decomposition for addition is associated with later mathematical achievement. This study examined how younger children execute a base-10 decomposition strategy to solve complex arithmetic (e.g. two-digit addition). 24 addition problems in two modalities (WA: Written Arithmetic; OA: Oral…

This study examines how sampled Chinese and U.S. third and fourth grade students (N[subscript China] = 167, N[subscript US] = 97) understand the commutative, associative, and distributive properties. These students took both pre- and post-tests conducted at the beginning and end of a school year. Comparisons between students' pre- and post-tests…

The importance of students being acquainted with algebraic ideas before secondary education has been revealed in the research literature. It is therefore essential that prospective elementary teachers (PTs) be prepared to instill an early algebra perspective in their teaching. However, PTs often show difficulties in algebra content knowledge,…

The Corona virus (COVID-19) crisis forced many countries to follow strict protocols ordering schools to close. With schools under lockdown, homeschooling has become the only form of schooling available. Reports have indicated that parents and students have struggled with the challenges of homeschooling. Against this background, this study explored…

In this study, we examined how much change in "TOEFL® Primary™" listening and reading scores can be expected in relation to the time interval between test administrations. The test records of 5213 young learners of English (aged 8-13 years) in Japan and Turkey who repeated the tests were analyzed to examine test scores as a function of…

Despite increased emphasis on the role of inclusive practices and materials in post-COVID-19 classrooms and warnings about implicit biases against disadvantaged groups, the textbook problem has rarely been approached with equity measures in mind. This multimethod study aimed to investigate to what extent L2 reading materials, locally produced and…

Despite calls for engaging assessments targeting young language learners (YLLs) between 8 and 13 years old, what makes assessment tasks engaging and how such task characteristics affect measurement quality have not been well studied empirically. Furthermore, there has been a dearth of validity research about technology-enhanced speaking tests for…

The present study tested the hypothesis that children's fluency with basic number facts and knowledge of computational strategies, derived from early arithmetic experience, predicts their performance on complex arithmetic problems. First-grade students from United States and Taiwan (N = 152, mean age: 7.3 years) were presented with problems that…

Differential item functioning (DIF) assessment is key in score validation. When DIF is present scores may not accurately reflect the construct of interest for some groups of examinees, leading to incorrect conclusions from the scores. Given rising immigration, and the increased reliance of educational policymakers on cross-national assessments…

International large-scale assessments of achievement often have a large degree of differential item functioning (DIF) between countries, which can threaten score equivalence and reduce the validity of inferences based on comparisons of group performances. It is important to understand potential sources of DIF to improve the validity of future…

This qualitative content analysis was conducted to determine how Mexico and Mexican people are portrayed in contemporary U.S. elementary social studies textbooks. Three textbooks from each of three major publishers were analyzed. Findings are presented in five sections: images and photographs, holidays, Mexican people and heroes, contested…

TIMSS (Trends in International Mathematics and Science Study) is an international assessment of mathematics and science at the fourth and eighth grades that has been conducted every four years since 1995, with the most recent assessment in 2011. PIRLS (Progress in International Reading Literacy Study) is an international assessment of reading…

Most cross-cultural research on Chinese and American children's early mathematical competencies has focused on their understanding of number and number operations. The present study broadened the range of tasks assessed to include geometric shapes, problem solving and logical reasoning, as well as number and numerical operations, in an effort to…

To date the authors have completed 23 studies of knowledge monitoring and its relationship to learning from instruction. Their earlier work, 12 studies in all, is summarized and reported elsewhere (see Tobias and Everson, 1996; Tobias and Everson, 2000). In this paper they continue this line of research and summarize the results of 11 studies that…
