This study examined the historical performance of students at Michigan State University in 12 life sciences courses over 13 yr to find variables impacting student success. Hierarchical linear modeling predicted 25.0-62.8% of the variance in students' grades in the courses analyzed. The primary predictor of a student's course grade was his or her…

Developmental trajectories of two self-concept constructs (self-confidence and importance beliefs) in three domains (academic, social, and self-image) were estimated in a nationally representative sample of approximately 3,500 students with disabilities ages 8 to 17 representing 11 federal disability categories. Students' self-confidence in the…

Observation competence plays a fundamental role in outdoor scientific investigation. The computerized concept mapping technique as a Mindtool has shown the potential for enhancing meaningful learning in science education. The purposes of the present study are to develop a concept map integrated mobile learning design for ecology observation and to…

Climate change science is a challenging topic for student learning. This quantitative study examined the effectiveness of a geospatial curriculum approach to promote climate change science understandings in an urban school district with eighth-grade students and investigated whether teacher- and student-level factors accounted for students'…

Prior research has documented that classroom-level variables have a significant effect on student outcomes; however, previous findings have typically focused on average student outcomes and have only recently begun to use hierarchical linear modeling techniques. The present study aimed to investigate the effects of classroom-level variables on the…

Despite the potential of differentiated curricula to enhance learning, limited research exists that documents their impact on Grade 3 students of all ability levels. To determine if there was a difference in achievement between students involved in 16 weeks of predifferentiated, enriched mathematics curricula and students using their district's…

Numerous authors have reviewed research to determine which skills are considered fundamental to successful academic and social outcomes for students (Hattie, Briggs, & Purdie, 1996; Masten & Coatworth, 1998; Wang, Haertel, & Walberg, 1994; Zins, Weissberg, Wang, & Walberg, 2004). These skills include: (1) cognitive and…

Career academies have been effective in reducing the high school dropout rates and increasing academic course taking and course credit accumulation among students (Kemple & Willner, 2008; Kemple & Snipes, 2000). However, not all students have access to career academy programs as they are not universally implemented across the state of…

Background: Deficient vocabulary is a frequently reported symptom of developmental language impairment, but the nature of the deficit and its developmental course are not well documented. Aims: To describe the nature of the deficit in terms of breadth and depth of vocabulary knowledge and to determine whether the nature and the extent of the…

National reports recognize a growing gender gap in postsecondary enrollment as a major challenge impacting the lives of young men, particularly African Americans. Previous gender and race specific research is largely inconclusive. It is, for example, unclear from previous research how persistent the gender gap is across various school contexts,…

Inequality in educational outcomes is a frequent topic of policy debate. This paper investigates one potential source of educational inequality--school safety. With panel survey data of middle school students, this paper estimates racial gaps in student feelings of safety in the classroom, in the hallways, and outside the school building, and how…

Recent studies have revealed how large shares of college-ready students "undermatch", or enroll in colleges with less competitive admissions processes than they are eligible to attend. Undermatch sits at the nexus of both college access and completion agendas, as undermatching to a less selective institution results in a decreased…

The purpose of this varied replication study was to evaluate the effects of a supplemental reading intervention on the beginning reading performance of kindergarten students in a different geographical location and in a different instructional context from the initial randomized trial. A second purpose was to investigate whether students who…

Social psychologists have suggested that language-based ideologies related to "stereotype threat" (i.e. variations in performance-based on ability perceptions of language groups) may affect students' academic achievement regardless of school language support. However, it is unclear whether efforts to support students' first language…

This study explores how teachers' shared perception of empowerment influences teacher efficacy and organizational commitment in the Chinese Mainland. A two-level hierarchical linear model is used to test the proposed theoretical framework. The results indicated that "professional growth", a school-level teacher empowerment factor, was…
