Students' ability to operate with increasingly more complex units has been shown to be a key factor in their conceptual development. These abilities have been characterized as "stages of units coordination." This article focuses on the domain of composing and decomposing composite units. Using data from a teaching experiment with a…

The "Pygmalion effect," is a construct that states that people often rise to the level that is expected of them (Chang, 2011). This is closely related to the "law of expectations," in which individuals receive what they expect to receive. These ideas may be applied to the educational arena when related to teacher perceptions…

American students continue to perform poorly on national and international assessments of Science, Technology, Engineering, and Mathematics (STEM) competencies, and achievement gaps spanning racial/ethnic and socioeconomic lines emerge early and widen over time. Scholars and practitioners agree that expanding access to high-quality STEM education…

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…

This 2-year longitudinal study examined relations between enjoyment of learning in Chinese and mathematics, two major subjects in Chinese schools, and indexes of school performance. The participants included 1041 students (501 boys) initially in third, fifth, and seventh grades (mean age = 10.49 years) in China. Data on enjoyment of Chinese and…

Effective mathematics education for Latinx students with learning disabilities (LD) necessitates teachers who uphold high academic expectations, facilitate access to rigorous math curricula, and champion inclusive and meaningful student participation. This study delves into teachers' perspectives on instructing Latinx students with LD, including…

This study was designed to investigate whether teacher literacy content knowledge affects student achievement in Texas schools. Teacher participants from Texas public schools completed a three-part survey. In Parts 1 and 2, teachers completed a demographic section and teacher knowledge of foundational reading skills. The survey consisted of…

Multiple regression data from a teacher-completed one-minute rating scale (i.e., the Brief Behavior, Academic, and Social Screener; B-BASS) predicted academic risk of 198 third- through fifth-grade rural elementary students; teacher ratings across 16 B-BASS items within cognitive, social/emotional, socioeconomic/family, and executive functions…

Extant work on the importance of children's executive function (EF) for academic skills typically employs either direct assessments of EF skills or adult reports of children's EF behaviors. Each approach has advantages, yet few studies have examined how different EF measurement approaches distinctly relate to child outcomes. We examined how direct…

The purpose of this study is to compare the social skills, problem behaviours and academic competence of gifted students at elementary level with their non-gifted peers, and to assess these based on the variables age, gender, and school year. The study group consists of 50 gifted students in second, third and fourth grade in state schools in…

Purpose: The objective of this study was to compare children with persistent versus transient preschool language delay on language, academic, and psychosocial outcomes in elementary school. Method: Children with persistent language delay (n = 30), transient language delay (n = 29), and no language delay (controls; n = 163) were identified from a…

The Common Core State Standards for Mathematics (CCSS-M) aim to engage students in complex mathematical practices, including modeling, reasoning, and argumentation. Currently, little is known about how teachers' daily instruction supports these practices. This study draws upon data from daily logs completed by third-, fourth-, and fifth-grade…

Since the first half of the 20th century, countries have begun to accelerate the education of gifted individuals in sports/arts and science and mathematics as a way of proving their superiority, and enabled these individuals to demonstrate their talents. There is a limited number of studies that measure the mathematics attitudes and academic…

This study used ClassMaps Survey to investigate third to fifth grade elementary students' perceptions of five relational (e.g., teacher-student relationships and peer friendships) and three individual (e.g., academic self-efficacy and behavioral self-control) resilience-promoting factors in classrooms in China and the United States. Examination of…

Students with early indicators of behavior risk have predictable, negative outcomes, and those with co-existing academic problems have significantly more negative outcomes. Identifying academic subclasses of students with behavior risk can inform integrated interventions and school-based problem-solving teams. In addition, identifying academic…
