This study combined the principles of multimedia message design with an enclosing-rectangle scaffold to facilitate instruction on deriving the area of basic geometric shapes. A pretest/posttest/delayed-posttest design was used to compare the effectiveness of the enclosing-rectangle scaffold with that of conventional dissection/rearrangement…

Recent research syntheses have identified several potentially high-leverage teaching strategies for improving low-attaining secondary school students' learning of mathematics. These strategies include the structured use of representations and manipulatives and an emphasis on derived facts and estimation. This paper reports on 70 semi-structured…

Research has been conducted on instructional leadership and the importance of instructional leadership, yet minimal research has been conducted on instructional leadership training models and principal perceptions on the impact of instructional leadership training on low performing schools. The problem addressed in this study was the current…

The purpose of this study was to determine how various security measures affect performance in two South Carolina middle schools, one high-performing, and one low-performing. This research study determined educators' attitudes toward safety in one high-performing and low-performing school in the low country area of South Carolina. There were five…

When individuals' attention shifts away from the primary tasks they are involved in, their minds start to wander. This mental phenomenon, also known as mind-wandering, can interact with other variables and affect the performance of academic tasks. The current study focuses particularly on the mind-wandering (MW) of Omani students while they were…

Background/Context: As part of a national movement to eliminate a global tracking system that disproportionately assigned underserved students to low-level math classes, the Chicago Public Schools (CPS) mandated academic algebra for all students entering high school in 1997. The results were disappointing: low-skill students experienced elevated…

Mississippi middle schools frequently fail to improve the intellectual capacity of students who struggle in mathematics. The purpose of this quantitative causal-comparative non-experimental research design was to investigate the impact of math academic interventions on rural Mississippi middle school mathematics students in grades six through…

One issue facing teachers who implement model-based instruction within the school system is the tight curricular schedule. The 'lesson objective tension' calls for investigations to address instructional issues such as how to organise modelling-based instruction at the curriculum level which is across multiple units. We investigated the effect of…

Historically marginalized students, especially urban students attending under-resourced schools, experience lower levels of belongingness than their white peers in suburban, well-resourced schools. Much research highlights that student belongingness increases student outcomes such as on-time graduation, standardized test achievement, and lifetime…

Running two separate two-stage randomized trials, we implement and test three variants of a small group instruction intervention aimed at improving mathematics competencies for the 20% lowest achievers in mathematics in grades 2 and 8 in Danish public schools. We calculate immediate impacts on math competencies as well as impacts in the medium…

Many U.S. students possess only a weak knowledge of fraction arithmetic. I hypothesize that textbooks are a critical reason for students' poor performance on fraction arithmetic. This is not because of what textbooks contain but rather because of what they lack. Distributions of fraction arithmetic problems in textbooks are imbalanced, with…

Student mobility that occurs within a school year may be especially disruptive for student outcomes, yet little is known regarding the predictors of within-year mobility. In particular, research has yet to comprehensively examine the role of student achievement in predicting within-year student mobility. Thus, we sought to understand this link by…

The "Next Generation Science Standards" call for engaging K-12 students in three-dimensional learning, in which students make sense of phenomena or solve problems by simultaneously using science and engineering practices (SEPs), crosscutting concepts (CCCs), and disciplinary core ideas (DCIs). Decades of education research suggest…

Advancing in key courses in ninth grade is an early, crucial step in preparing for college. Students who miss academic targets early in high school may not be ready to go to college 4 years later. In the United States, when students fail key courses in ninth grade, they may struggle to catch up to their peers who successfully took and passed these…

This study was aimed to reveal what types of questions were asked by pre- service teachers and what kind of interactions they established with the 5th-8th grade students. The extent to which the questions the pre-service teachers asked are related to the interactions they established with the students was also investigated. Case study, one of the…
