In many countries, standardized math tests are important for achieving academic success. Here, we examine whether content of items, the story that explains a mathematical question, biases performance of low-SES students. In a large-scale cohort study of Trends in International Mathematics and Science Studies (TIMSS)--including data from 58…

Early detection of and relevant information on children's mathematical difficulties is important to initiate targeted teaching and intervention. This study investigated the extent to which strategy use in single-digit addition provides additional predictive information about 61 grade one children's (6-year-old) mathematical achievement 3 years…

Background: PIRLS 2021 results revealed that South African Grade 4 learners performed significantly lower compared to other countries in reading comprehension and that they did not reach the standardised international mean score of 500. It was also evident from the results that English learners performed relatively higher than isiZulu learners.…

A jurisdiction-wide zero-stakes Foundational Skills Assessment administered in grade 4 in British Columbia, Canada, used a three-point scale to publicly disseminate aggregate school/district-level results, and a five-point scale to convey results to students/parents. For a variety of long-term outcomes, a regression discontinuity analysis shows a…

This paper examines the relationship between teacher pay and students' academic achievement, using nationally representative, district-level linked data between districts' performance on standardized tests and average teacher base salary. By employing state fixed effects and multilevel mixed effects models, we find that both mathematics and…

In the United States, national and state standardized assessments have become a metric for measuring student learning and high-quality learning environments. As the COVID19 pandemic offered a multitude of learning modalities (e.g., hybrid, socially distanced face-to-face instruction, virtual environment), it becomes critical to examine how this…

School closures due to the COVID-19 pandemic raised concerns about increases in educational inequality. We examined the magnitude of the impact of the first school closure for vulnerable student groups in particular. This study was conducted among 886 Grade 3-5 students in the Netherlands in schools serving a high percentage of students from…

Math programming that includes assessments to predict standardized mathematics scores can help evaluate student performance and growth during the academic year. ACALETICS® is a highly interactive, culturally inclusive mathematics program that utilizes posttests as continuous comprehensive assessments to evaluate student mathematical knowledge.…

A 7-month mathematics proficiency program was conducted in a primary Australian Indigenous community school. This paper focuses on outlining the specific methodologies employed to explore how students' mathematical proficiency changed throughout the implementation of the program in Years 2 to 4 (~ 7 to 9 years old). A mixed methods research design…

This article contributes to the larger narrative around what makes a mathematics professional development (PD) successful and in what ways. We share a research-based PD model that was implemented in elementary schools in an urban school district for 3 years. The model uses a pseudo lesson study approach and emphasizes standards-based instruction.…

Research suggests that executive function, motivation, transcription, and composition processes are implicated in the writing quality and productivity of children with and without learning difficulties. However, numerous components embedded within these constructs create both conceptual and empirical challenges to the study of written expression.…

Purpose: A growing trend in instructional improvement efforts is the use of formative assessment informed by research-based developmental trajectories of how students gain deeper understanding of subject matter content over time. This article reports the findings of a large-scale experimental study of an innovative mathematics professional…

Linking score scales across different tests is considered speculative and fraught, even at the aggregate level. We introduce and illustrate validation methods for aggregate linkages, using the challenge of linking U.S. school district average test scores across states as a motivating example. We show that aggregate linkages can be validated both…

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…

Background: Reading comprehension is a complex process influenced by many factors. However, the abilities that are known to influence reading comprehension may not contribute equally for children with different levels of oral language. Aims: Here we examined the relationship of two factors known to influence reading comprehension (morphology and…
