Background: Base-ten thinking (BTT) -- children's ability to reason in tens and ones is a crucial measure of Foundation Phase learners' mathematical performance in South Africa. Aim: The study looks at the six learners using BTT to solve additive tasks through two different assessments. Setting: Six purposely selected Grade 3 learners in…

This technical assistance paper provides policy and guidance to individuals with test administration responsibilities in adult education programs. Rule 6A-6.014, Florida Administrative Code (F.A.C.), General Requirements for Adult General Education Programs, provides a list of assessments that are approved by the U.S. Department of Education (ED)…

For over 50 years, the National Assessment of Educational Progress (NAEP), the Nation's Report Card, has measured student achievement in reading and math across the United States. The recently released 2024 results confirm a long-term crisis in education, with student performance stagnating or declining despite decades of federal spending and…

State education agencies are sitting on rich repositories of quantitative and qualitative assessment data. This document is designed to provide a conceptual framework and implementation guidance that can help agency leadership leverage and interrogate student performance data in systematic ways for reporting, outreach, and planning purposes. The…

This open access book presents original research on effective and equitable teacher practice in mathematics and science education across Nordic countries. It focuses on three key aspects of teacher practice: what teachers teach, how teachers teach, and how teachers assess their students. To provide a comprehensive understanding of teacher…

Advancement of testing of mathematical problem-solving skills calls for open-ended, realistic tasks particularly susceptible to bias, compromising the score validity and fairness of tests. Informed by universal design principles, this study framed 360 prototype items developed for the "Problem-solving Measures Grades 6-8 Computer Adaptive…

A solid understanding of fractions is the cornerstone for acquiring proficiency with rational numbers and paves the way for learning advanced mathematical concepts, such as algebra. Fraction difficulties limit not only students' educational and vocational opportunities but also their ability to solve everyday problems. Students who exit 6th grade…

With this article I explore the relationship between core academic language skills (CALS) -- a construct representing a set of high-utility language skills needed to manage the linguistic features prevalent in academic texts across content areas -- and schooling outcomes. There has long been an understanding that there is a distinction between…

Years of teaching experience have long been taken as an important indicator of teacher and school quality in primary and secondary schools. However, research on the effects of teacher years of experience on student outcomes has shown mixed results. To investigate the source of variation causing these mixed results, this study examined a broad…

When researchers code behavior that is undetectable or falls outside of the validated ordinal scale, the resultant outcomes often suffer from informative missingness. Incorrect analysis of such data can lead to biased arguments around efficacy and effectiveness in the context of experimental and intervention research. Here, we detail a new…

Summative assessments measure students' mastery of grade-level academic standards and skills in specific content areas after learning. State summative assessment systems provide students and families, school and district leaders, and state policymakers with valuable data to help understand student progress and school quality. This Policy Guide…

The study examined the relationship between children's explicit knowledge and awareness of diglossia (EKAD) and learning Arabic in school. Additionally, this study addresses the interrelationships between EKAD and oral comprehension, lexical, phonological, and morphosyntactic awareness upon the transition to reading to learn. Thirty typicaly…

The purpose of this study is to explore preservice teachers' (PTs') ability to implement multiple strategies using standard algorithms and alternative strategies and to investigate their conceptual knowledge of decimal operations. There were 37 PTs who participated in this study, all of whom attended a mathematics course in the K-8 Teacher…

This study explores benefits of studying two related subjects, mathematics and physics, in teacher education. German teacher students study two subjects as a major, which allows for investigating how the development of content knowledge in one subject, mathematics, benefits students' content knowledge in the other subject, physics. The sample…

The aim of this research is to describe and explore the statistical literacy of middle school students in solving the Trends in International Mathematics and Science Study (TIMSS) problems. This research utilized the qualitative approach, with the research type being descriptive-explorative. The research subjects consisted of 6 Grade 8 students…
