Background: Performance with fractions has been a weak point in U.S. education for decades and has not improved in recent years (Siegler, 2017). High School math teachers frequently rate their students' knowledge of fractions as "poor" and see this lack of foundational knowledge as one of the top barriers to students mastering algebra…

While symbolic number processing is an important correlate for typical and low mathematics achievement, it remains to be determined whether children with high mathematics achievement also have excellent symbolic number processing abilities. We investigated this question in 64 children (aged 8 to 10), i.e., 32 children with persistent high…

The shift from additive to multiplicative thinking is challenging for students. A professional learning program was developed that focused on an identified area of need by teachers, namely multiplicative thinking. Program content focused on concepts underpinning multiplicative thinking, pedagogical approaches, challenging tasks, and application to…

Recently, virtual reality seems to be deevloping rapidly. However, it can be said that virtual reality is in the early days of adoption for education. Studies show that using virtual reality in education can positively affect students' learning experiences. In this study, the effect of an educational virtual reality game, named "Kesfet…

In the present study, we investigated the impact of a word-problem intervention in retention and acquisition of knowledge after the intervention ended. We based analyses upon Grade 4 students experiencing mathematics difficulty (average age at pretest = 8.77) who received one of two variants of a word-problem intervention (with [n = 111] vs.…

One of the main objectives of international large-scale assessments is to make comparisons between different countries, education policies, education systems, or subgroups. One of the main criteria for making comparisons between different groups is to ensure measurement invariance. The purpose of this study was to test the measurement invariance…

Five groups rank state charter school environments according to their laws, regulations, funding, and other characteristics, but none rank states by charter student performances on a national test. We rank states by demographically adjusted math and reading performances of charter students in 4th and 8th grade for the period 2009 to 2019 on the…

Research has shown that some students who underperform in mathematics overestimate their performance, while others who excel in mathematics underestimate it. Looking at this mismatch of performance and confidence judgement--the Dunning-Kruger effect (DKE)--the current study investigates how well students' confidence judgement and item-specific…

This study compared students' performance on Istation, a computer-based progress-monitoring tool, and easyCBM, a paper-pencil progress-monitoring tool. Participants included 106 students in Grades K-6 from a rural school in New Mexico. Teachers in these grade levels administered both assessments three times during the school year. Results…

The main purpose of the present study was to develop and apply a mathematics program that meets the academic and mental needs of gifted and talented primary school students during distance education and to test the effectiveness of the program. The current study involved 120 gifted and talented fourth-grade students, 60 of whom were in the…

We examined how children (N = 448) with separate or co-occurring developmental language disorder (DLD) and dyslexia performed on school-based measures of academic functioning between second and fourth grades. Children were recruited from 1 school district in the U.S. state of South Carolina via classroom screenings and met common research criteria…

Replication studies in special education are necessary to strengthen the foundation upon which instruction and intervention for students with disabilities are built. J. Jenkins et al. (2017) found intermittent reading fluency progress monitoring schedules did not delay decision-making and were similar in decision-making accuracy to the traditional…

Standardized testing results in fourth-grade math have shown that students in the United States continually score below students in many other nations, despite funding education at levels well above the global average. The problem addressed in this study was that fourth-grade math students in the United States were not performing as well on…

The main purpose of this study was to explore the relationship between students' social-emotional learning (SEL), as demonstrated by the competencies of grit, growth mindset, and self-management, and students' academic achievement, measured by their proficiency in reading, language usage, and mathematics. This study also sought to compare the…

In this study, we illustrated an application of the confirmatory mixture IRT model for multidimensional tests. We aimed to examine the differences in student performance by domains with a confirmatory mixture IRT modeling approach. A three-dimensional and three-class model was analyzed by assuming content domains as dimensions and cognitive…
