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…

We report the results of a preregistered, cluster randomized controlled trial of a mathematics learning intervention known as interleaved practice. Whereas most mathematics assignments consist of a block of problems devoted to the same skill or concept, an interleaved assignment is arranged so that no 2 consecutive problems require the same…

Student-teacher relationships are important to student outcomes and may be especially pivotal at the high school transition and for minoritized racial/ethnic groups. Although interventions exist to improve student-teacher relationships, none have been shown to be effective among high school students or in narrowing racial/ethnic disparities in…

A growing body of correlational research finds a relationship between self-efficacy--beliefs in one's capabilities--and academic success. But few studies have investigated whether self-efficacy is causally related to academic success. We hypothesized that an experience of success would promote self-efficacy in junior high school students and would…

We report the results of a pre-registered, cluster randomized controlled trial of a mathematics learning intervention known as interleaved practice. Whereas most mathematics assignments consist of a block of problems devoted to the same skill or concept, an interleaved assignment is arranged so that no two consecutive problems require the same…

Although some literature reviews cited mixed results for group-based social competence interventions in schools, existing descriptions of intervention efficacy often lack attention on important factors that may moderate differential response. Some studies suggest that individual characteristics such as diagnosis (i.e., specific deficit clusters)…

In the United States, school-based mentoring programs are a large and widely funded form of mentoring. Despite widespread support, meta-analyses indicate that the effects of school-based mentoring programs are small. One hypothesis for these results is that school-based mentors are not able to develop a sufficiently high-quality relationship with…

Recent methods to improve generalizations from nonrandom samples typically invoke assumptions such as the strong ignorability of sample selection, which is challenging to meet in practice. Although researchers acknowledge the difficulty in meeting this assumption, point estimates are still provided and used without considering alternative…

Deficits in academic vocabulary knowledge plague students who struggle with reading and impact their reading comprehension and performance in content area courses. Experts have developed interventions aimed at improving vocabulary instruction. However, questions remain concerning the effects of vocabulary gains on reading comprehension and content…

This study evaluated effects of Positive Action (PA), a school-based social-emotional and character development program, on self-esteem levels and processes among minority, low-income, urban youth. A matched-pair, cluster-randomized controlled trial was conducted in 14 Chicago Public Schools with outcomes assessed longitudinally for a cohort of…

The purpose of the study was to develop a powerful and empowering guide (CBT) of elementary school teachers, to compare the ability of elementary school teachers. Management learning uses brain as a base. The experimental group with a control group the experimental group used in this research was a teacher at the grade level. 4-6 in province By…

This article reports results from a study investigating the efficacy of a proportional problem-solving intervention, schema-based instruction (SBI), in seventh grade. Participants included 806 students with mathematical difficulties in problem solving (MD-PS) from an initial pool of 1,999 seventh grade students in a larger study. Teachers and…

Recent studies [10, 23] using US nationwide databases showed high school boys spent significantly less time doing homework than girls, based on their responses to questionnaires and surveys. To investigate gender differences in homework in middle school, in this paper, we analyzed computer log data and standardized test scores of more than 1,000…

Purpose: We examined the effects of a text-processing reading comprehension intervention emphasizing listening comprehension and expressive language practices with middle school students with reading difficulties. Method: A total of 134 struggling readers in grades 6-8 were randomly assigned to treatment (n = 83) and control conditions (n = 51)…
