We present our analysis of 254 Calculus I final exams from U.S. colleges and universities to identify features of assessment items that necessitate qualitatively distinct ways of understanding and reasoning. We explore salient features of exemplary tasks from our data set to reveal distinctions between exam items made apparent by our analytical…

This study examines the role of self-concept regarding mathematical ability in explaining the gender gap in advanced mathematics performance of US high school students. The study is based on data generated from the Third International Mathematics and Science Study (TIMSS 1995-2015), a large-scale project which investigated the relationship between…

The COVID-19 pandemic inflicted massive disruptions on all aspects of daily life, not least of which was the education of K-12 students. It is accepted wisdom among many educational researchers that students need face-to-face instruction from certified teachers in order to flourish. But because students in many districts were forced to stay home…

This study aims to examine the strategies developed by 7th grade students while shading different percentages of geometric shapes. The study was carried out with 113 7th graders studying at a state middle school in a province of Turkey. The data were gathered using the Shading Percentage Test, which consisted of seven tasks. Data analysis employed…

The literature has amply shown that primary and secondary school students have difficulties in understanding rational number size. Many of these difficulties are explained by the natural number bias or the use of other incorrect reasoning such as gap thinking. However, in many studies, these types of reasoning have been inferred from comparing…

Little is known about the cognitive effort associated with algebraic activity in the elementary and middle school grades. However, this investigation is significant for sensitizing teachers and researchers to the mental demands of algebra learning. In this paper, we focus on the relationship between algebraic thinking and domain-general cognitive…

The general objective to be achieved in this study is to determine the effect of using Blended Learning in terms of Intrapersonal Intelligence on Problem Solving Ability. This research is a quasi-experimental research with a two × three factorial design. Documentation, questionnaires, and tests were carried out the data collection method. The…

The aim of this study is to examine the effects of Realistic Mathematics Education (RME) on 7th grade students' achievement on integer operations and their attitudes towards mathematics and to determine students' views about the RME approach. The research was carried out with the participation of 11 students. Exploratory sequential mixed design…

Up to 1.0% of the total tested state student population in a subject area may participate in the alternate assessment based on alternate academic achievement standards (AA-AAAS). This Brief presents the results of analyses of states' AA-AAAS participation rates from 2015-16 through 2018-19. Information is presented on: (a) the number of states…

Following the COVID-19 pandemic, students returned to the classroom facing heightened challenges. Students lacked motivation, struggled with increased mental health issues, and required social emotional learning. As teachers worked extensively to close deep academic deficits, they dealt with barriers such as increased behaviors that caused…

The lack of access to high-quality schools creates an achievement gap that limits students' access to future earnings and longevity, exacerbating equity concerns across the nation where struggling, low-performing schools are disproportionately responsible for educating students living in poverty. Large Urban School District's Accelerating Campus…

We report the validity of a test instrument that assesses the arithmetic ability of primary students by (a) describing the theoretical model of arithmetic ability assessment using Wilson's (2004) four building blocks of constructing measures and (b) providing empirical evidence for the validation study. The instrument consists of 21…

This study aimed to examine the diagrammatic representation skills and problem-solving performances of students according to their problem-solving representations. A cross-sectional survey design using quantitative methods was used in this study. The sample consisted of 31 second-grade and 41 third-grade students from a public primary school in…

Globally girls' performance in mathematics has improved over the years as measured by TIMSS results. Inconsistency in mathematics performance of boys and girls is still an area of great concern. This study examines the relationship between mathematics achievement and gender of South African Grade 9 learners from TIMSS 2015 data. The data were…
