Algebra I is a crucial course for middle and high school students for successful STEM-related coursework. A key issue is whether students should take Algebra I in Grade 8 versus Grade 9. Large-scale policy studies show conflicting results, and there are few (particularly longitudinal) individual difference studies. In the study, 53 students were…

The current research was conducted to find out the effect of parenting styles of both fathers and mothers on academic achievement of the underachiever and high achiever children. A sample of 210 participants including 70 students (35 low achievers and 35 high achievers) and their 70 parents (both fathers and mothers) was purposefully selected. The…

This study examines differences in English language comprehension, reading fluency, and executive functions among Spanish-English bilinguals with reading difficulties. Reading difficulties examined included general reading difficulties, defined by low word reading and reading comprehension, and specific-reading comprehension difficulties, defined…

This study examines differences in English language comprehension, reading fluency, and executive functions among Spanish-English bilinguals with reading difficulties. Reading difficulties examined included general reading difficulties, defined by low word reading and reading comprehension, and specific-reading comprehension difficulties, defined…

The motivational impact of messages about how to interpret experienced difficulty with schoolwork was tested in two studies. Students read that experienced difficulty with schoolwork is a signal either of the importance or of the impossibility of succeeding in school, rated how much they agreed, and completed a difficult task (Raven's Progressive…

The contributions of domain-general abilities and domain-specific knowledge to subsequent mathematics achievement were longitudinally assessed (n = 167) through 8th grade. First grade intelligence and working memory and prior grade reading achievement indexed domain-general effects, and domain-specific effects were indexed by prior grade…

Objective: The primary objective of this study was to evaluate the prevalence of multiple types of sleep problems in young adolescents with ADHD. Method: 262 adolescents comprehensively diagnosed with ADHD and their caregivers completed well-validated measures of sleep problems and daytime sleepiness. Participants also completed measures related…

The psychometric qualities of the six- and eight-item implicit theories of intelligence scales that Dweck suggested were compared using a confirmatory factor analysis with data from 239 gifted students (100 students in Grades 5-7, 139 students in Grades 8-11). The results indicate that the six-item scale fits the data better than the eight-item…

The present study explores the extent to which maternal attachment and teacher--student attachment-like relationships explain the socioemotional adaptation of students with disabilities. Participants consisted of 65 dyads of homeroom teachers and their students (from a middle-to-low-class area in Northern Israel) with learning disabilities (LD),…

This study utilized multilevel modeling to examine the student characteristics (gender and age) and school factors (private vs. public school, urban vs. rural school, socioeconomic status, curricular organization, resources, activities, and equipment) associated with individual and between-school differences in the verbal, numerical, and figural…

The research base on how to effectively intervene to improve the reading fluency of students with academic and behavioral disabilities at the middle school level does not provide a strong support for evidence- based practices with this age group. The purpose of this study was to extend the body of research on reading fluency interventions to…

We evaluated the effects of student characteristics (sight word reading efficiency, phonological decoding, verbal knowledge, level of reading ability, grade, gender) and text features (passage difficulty, length, genre, and language and discourse attributes) on the oral reading fluency of a sample of middle-school students in Grades 6-8 (N =…

Emotional intelligence (EI) theory provides a framework to study the role of emotion skills in social, personal, and academic functioning. Reporting data validating the importance of EI among youth have been limited due to a dearth of measurement instruments. In two studies, the authors examined the reliability and validity of the…

We studied developmental trends in 5 important reasoning tasks that are critical components of the operational definition of rational thinking. The tasks measured denominator neglect, belief bias, base rate sensitivity, resistance to framing, and the tendency toward otherside thinking. In addition to age, we examined 2 other individual difference…

This report described how implementation of differentiated assignments provided documentation of how students' motivation increased. The volunteers that participated in this study were 6th, 7th, and 8th graders. Students struggle academically to meet the expectations of their instructors. These struggles impact how students learn academically,…
