We analyse the PISA-reported convergence in the performance of private and public schools in Portugal. When PISA sampling weights are used, the number of students enrolled in those types of schools and specific grades/tracks of study differs significantly from official population figures. To account for those differences, we apply a…

Developing an understanding of fractions is critical as a significant predictor for the learning progression of advanced domains; however, students face significant challenges in learning fractions because of their unique properties. To systematically approach remediation, this study examined the common error patterns committed by middle-school…

One major aim of international large-scale assessments (ILSA) like PISA is to monitor changes in student performance over time. To accomplish this task, a set of common items (i.e., link items) is repeatedly administered in each assessment. Linking methods based on item response theory (IRT) models are used to align the results from the different…

Problem-solving is one of the 21st-century skills. However, students still have difficulty solving sequences and series word problems. The purpose of this research is to analyze students' errors in solving sequences and series word problems based on problem-solving steps of Polya. The research method is descriptive qualitative. The research…

This study investigated cognitive patterns of strengths and weaknesses (PSW) and their relationship to patterns of math errors on the Kaufman Test of Educational Achievement (KTEA-3). Participants, ages 5 to 18, were selected from the KTEA-3 standardization sample if they met one of two PSW profiles: high crystallized ability (Gc) paired with low…

This article addresses test translation review in international test comparisons. We investigated the applicability of the theory of test translation error--a theory of the multidimensionality and inevitability of test translation error--across source language-target language combinations in the translation of PISA (Programme of International…

The United States invented a matrix sampling technique to impute five plausible scores of student performance in its National Assessment of Educational Progress. That approach was adopted by a Trend in Mathematics and Science Study (TIMSS) for international comparison. In this paper, baseline data from TIMSS 1995 are analyzed at the seventh grade…

"U.S. Performance on the 2015 TIMSS Advanced Mathematics and Physics Assessments: A Closer Look" expands upon the results described in NCES' [National Center for Education Statistics'] initial "Highlights" report on TIMSS Advanced. This new report provides in-depth analyses that (1) examine the demographics, school…

Although word reading has traditionally been viewed as a foundational skill for development of reading fluency and comprehension, some children demonstrate "specific" reading comprehension problems, in the context of intact word reading. The purpose of this study was to identify specific patterns of errors associated with reading…

We investigated whether consensus-based test translation review procedures can be used effectively in cultural contexts with high social stratification. We staged two test translation review panels in China -- where social stratification may potentially inhibit individuals' ability to express opinion and disagreement. We adapted a consensus-based…

Norm-referenced error analysis is useful for understanding individual differences in students' academic skill development and for identifying areas of skill strength and weakness. The purpose of the present study was to identify underlying connections between error categories across five language and math subtests of the Kaufman Test of…

A large body of research has documented the relationship between attention-deficit hyperactivity disorder (ADHD) and reading difficulties in children; however, there have been no studies to date that have examined errors made by students with ADHD and reading difficulties. The present study sought to determine whether the kinds of achievement…

Building on the sociological work by Lareau, this study examined the association between students' socioeconomic background, prior achievement and the perception of teacher support within the classroom. We expected that students from higher socioeconomic backgrounds would be more critical about the support they receive in the classroom and rate…

This study investigated the relationship between specific cognitive patterns of strengths and weaknesses (PSWs) and the errors children make in reading, writing, and spelling tests from the Kaufman Test of Educational Achievement-Third Edition (KTEA-3). Participants were selected from the KTEA-3 standardization sample based on five cognitive…

It has been hypothesized that students with dyslexia struggle with writing because of a word-level focus that reduces attention to higher level textual features (structure, theme development). This may result from difficulties with spelling and/or difficulties with reading. Twenty-six Norwegian upper secondary students (M = 16.9 years) with weak…
