Li, Jian; O'Connell, Ann A. – Journal of Educational Research, 2012
The authors investigated children's self-reported high-calorie food intake in Grade 5 and its relationship to trends in obesity status and academic achievement over the first 6 years of school. They used 3-level hierarchical linear models in the large-scale database (the Early Childhood Longitudinal Study--Kindergarten Cohort). Findings indicated…

O'Connell, Ann A.; Reed, Sandra J. – New Directions for Institutional Research, 2012
Multilevel modeling (MLM), also referred to as hierarchical linear modeling (HLM) or mixed models, provides a powerful analytical framework through which to study colleges and universities and their impact on students. Due to the natural hierarchical structure of data obtained from students or faculty in colleges and universities, MLM offers many…

O'Connell, Ann A.; Gray, DeLeon L. – Educational Psychology Review, 2011
Efforts to identify and support credible causal claims have received intense interest in the research community, particularly over the past few decades. In this paper, we focus on the use of statistical procedures designed to support causal claims for a treatment or intervention when the response variable of interest is dichotomous. We identify…

Liu, Xing; O'Connell, Ann A. – Online Submission, 2008
Childhood is the crucial period for early children's reading ability building. Former research (Hanson & Farrell, 1995) found that early reading experience had a positive and long-term effect on reading competence for high school seniors in the future. Therefore, it is of great importance for researchers to understand children's initial reading…

Gray, DeLeon L.; Anderman, Eric M.; O'Connell, Ann A. – Social Psychology of Education: An International Journal, 2011
In the present study (N = 633), we examine the role of teacher credibility and teacher affinity in classrooms. We explore the relations among these two characteristics and student gains in knowledge and valuing of learning about HIV and pregnancy prevention across high school classrooms. Results marshaled support for the notion that teacher…

Sackes, Mesut; Trundle, Kathy Cabe; Bell, Randy L.; O'Connell, Ann A. – Journal of Research in Science Teaching, 2011
This study explores the impacts of selected early science experiences in kindergarten (frequency and duration of teachers' teaching of science, availability of sand/water table and science areas, and children's participation in cooking and science equipment activities) on children's science achievement in kindergarten and third grade using data…

McCoach, D. Betsy; Black, Anne C.; O'Connell, Ann A. – Psychology in the Schools, 2007
Although structural equation modeling (SEM) is one of the most comprehensive and flexible approaches to data analysis currently available, it is nonetheless prone to researcher misuse and misconceptions. This article offers a brief overview of the unique capabilities of SEM and discusses common sources of user error in drawing conclusions from…

McCoach, D. Betsy; O'Connell, Ann A.; Levitt, Heather – Journal of Educational Research, 2006
Regardless of individual differences at kindergarten entry, schools have a mission to promote reading achievement for all students. Within-class ability grouping is an instructional strategy that has received attention for its potential benefits to students. The authors assessed the effects of within-class ability grouping on kindergarten reading…

Osborn, Chandra Y.; Amico, K. R.; Cruz, Noemi; O'Connell, Ann A.; Perez-Escamilla, Rafael; Kalichman, Seth C.; Wolf, Scott A.; Fisher, Jeffrey D. – Health Education & Behavior, 2010
The information-motivation-behavioral skills (IMB) model of health behavior change informed the design of a brief, culturally tailored diabetes self-care intervention for Puerto Ricans with type 2 diabetes. Participants (n = 118) were recruited from an outpatient, primary care clinic at an urban hospital in the northeast United States. ANCOVA…

McCoach, D. Betsy; O'Connell, Ann A.; Reis, Sally M.; Levitt, Heather A. – Journal of Educational Psychology, 2006
Using the first 4 waves of data from the Early Childhood Longitudinal Study-Kindergarten cohort (ECLS-K), this piecewise 3-level (time-student-school) growth-curve model provides a portrait of students' reading growth over the first 2 years of school. On average, students make much greater reading gains in 1st grade than they do in kindergarten.…

Bol, Linda; Stephenson, Patricia L.; O'Connell, Ann A.; Nunnery, John A. – Journal of Educational Research, 1998
Explored teachers' self-reported assessment practices and the influence of teaching experience, grade level, and subject area on those practices. Surveys of 893 teachers in 34 schools indicated that they used observational assessment and performance tasks more frequently than traditional assessment. Experienced teachers, elementary teachers, and…
