The profession of teaching is inherently stressful. Resilience, or the ability to adapt and develop competence despite exposure to disruptive change, has been shown to be beneficial for teachers. The purpose of this study was to determine if personal resilience is a predictor of professional development engagement and career satisfaction of…

We examined the prediction that the interaction between Glucocorticoid Receptor Gene ("NR3C1") methylation, stress, and experienced maternal support predicts anxious and avoidant attachment development. This was tested in a general population sample of 487 children and adolescents (44% boys, M[subscript age] = 11.84, SD[subscript age] =…

Student learning in instructional physics labs represents a growing area of research that includes investigations of students' beliefs and expectations about the nature of experimental physics. To directly probe students' epistemologies about experimental physics and support broader lab transformation efforts at the University of Colorado Boulder…

Background: The purpose of this evaluation was to examine the effects of the LiveWell@School Food Initiative (LW@SFI), a Colorado-based childhood obesity prevention program that partners with school districts to enable them to serve more scratch cooked foods through culinary training, action planning, and equipment grants. Methods: This evaluation…

Background: Research on strategies for addressing multiple health-related behaviors (HRBs) in one intervention are needed because resources are sparse and clarification is needed regarding the relationship between multiple HRBs. Purpose: Determine undergraduate students' health behavior co-occurring pairs of smoking cigarettes (SC), alcohol…

This study is to investigate whether "My Class Activities" (MCA; Gentry & Gable, 2001a), an instrument developed to measure students' perceptions of their classroom activities, yields valid data when used with elementary students in China after translation into Chinese. The four factors measured by the instrument (Interest,…

Maternal immune activity has been linked to children with autism spectrum disorder (ASD). We examined maternal occupational exposure to asthma-causing agents during pregnancy in relation to ASD risk. Our sample included 463 ASD cases and 710 general population controls from the Study to Explore Early Development whose mothers reported at least one…

Background: Cluster randomized experiments that assign intact groups such as schools or school districts to treatment conditions are increasingly common in educational research. Such experiments are inherently multilevel designs whose sensitivity (statistical power and precision of estimates) depends on the variance decomposition across levels.…

As state tests of student achievement are used for an increasingly wide array of high- and low-stakes purposes, evaluating their instructional sensitivity is essential. This article uses data from the Bill and Melinda Gates Foundation's Measures of Effective Project to examine the instructional sensitivity of 4 states' mathematics and English…

General biology courses (for majors) are often transferred from one institution to another. These courses must prepare students for upper division courses in biology. In Colorado, a Biology Transfer Articulation Agreement that includes general biology has been created across the state. An evaluation was conducted of course grades in two upper…

Purpose/Objectives: The purpose of this study was to determine: (1) What foods high school students participating in the National School Lunch Program (NSLP) are discarding the most? (2) How much of these foods they are discarding? and (3) What are their perceptions towards school lunch? Methods: Researchers measured plate waste at two high…

This report examines the relationship between socioeconomic status, as defined by a free-and-reduced lunch proxy variable, and student growth percentiles by elementary, middle, and high school grade levels for math, reading, and writing. Comparisons were made between median growth percentiles for each educational level by free and reduced lunch…

This study explored learning and teaching of online classes. Examining the relationship between undergraduate students' participation and their final grades in five selected courses in an online learning environment and exploring differences between the demographics characteristics of age, race, and gender to students' participation (total number…

This study investigates the interrelationship of categorical funding mechanisms within the Colorado school finance system for English language learners (ELLs) in an effort to test overall equity of the system in light of an underfunded categorical program. Using several analytical techniques, the study set out to determine the degree to which…

The purpose of this exploratory study was to analyze how high school principals approached developing a collaborative culture and providing collaborative leadership in a large high school setting. The population sample for this study was 82 principals of large comprehensive high schools of grades 9 through 12 or some combination thereof with…
