Compositional effects of scholarly culture classroom/school climate on civic knowledge scores of 9th graders in the United States were examined using the International Association for the Evaluation of Educational Achievement (IEA) 1999 Civic Education Study data. Following Evans et al. (2010, 2014), we conceived that the number of books at home,…

In most large-scale programs of tests that aid in making high-stakes decisions, such as the "TOEIC"® family of products and service, it is not unusual for a significant portion of test takers to retake the test at multiple times.The study reported here used multilevel growth modeling to explore the score change patterns of nearly 20,000…

With the ever-increasing availability of online education opportunities, understanding the factors that influence online student satisfaction and success is vital to enable administrators to engage and retain this important stakeholder group. The purpose of this ex-post-facto, nonexperimental quantitative study was to investigate the impact of…

Community colleges are an integral part of the postsecondary education system in the United States. Unfortunately, college completion rates continue to decline. Additionally, median income in the United States is also declining. The idea that each successive generation of students will do better than the previous one is quickly becoming a fantasy.…

The vocabulary size of 16- to 30-month-old children (N = 1235) was assessed using the Estonian adaptation of the MacArthur-Bates Communicative Development Inventory: Words and Sentences (ECDI-II). The relationship between children's expressive vocabulary size and different factors of the child and his/her social environment was examined. Results…

Prior research has shown that greatest student achievement in sciences is attributed to "inquiry-based instructional approach", in which the goal of science teaching is nurturing attitudes and skills necessary for independent quest for scientific knowledge. While prior research has clearly demonstrated positive instructional effects of…

Collaborative learning has been found to benefit students in various disciplines. Moreover, in the science, technology, engineering, and mathematics literature, it was noted that minority students benefited the most from collaborative learning. Studies on the effects of collaborative learning in communication are limited. As a result, I examined…

A variety of factors contributes to student achievement in mathematics, including but not limited to student behaviors and student, teacher, and school characteristics. The purpose of this study was to explore which of these factors have an impact on student mathematics achievement. The target population for this study was North Carolina Algebra…

Given the negative outcomes associated with suspension, scholars and practitioners are concerned with discipline disparities. This study explored patterns and predictors of suspension in a sample of 2,750 students with disabilities in 39 schools in a Midwestern district. Hierarchical generalized linear modeling demonstrated that disability type,…

This study used data from the Head Start Family and Child Experiences Survey (FACES) 2009 4-year-old cohort to examine associations among family characteristics, home and classroom environments, and the emergent literacy skills of Head Start children. Results from hierarchical linear models suggest that both family and classroom contexts play a…

This study examined (1) average distances traveled to attend college, (2) presumptive college eligibility, (3) differences between two-year and four-year college enrollment, (4) differences in enrollment related to differences in colleges' selectivity, and (5) degree of "undermatching" (i.e., enrolling in a college less selective than…

Sexual minority students such as those identifying as lesbian, gay, or bisexual, as well as those identifying with emerging self-labels (e.g., queer) face a host of risk factors in high school that can potentially compromise educational excellence, particularly in rigorous academic disciplines. The current study advances the area of diversity…

To compete in the global marketplace, the U.S. economy heavily relies on higher education institutions to educate the college graduates and knowledge workers needed to create the innovative products and services of tomorrow. And yet, where once America led the world in educational attainment, recent data from the Organization for Economic…

This study investigated the unique relations between school concentrations of student risk factors and measures of reading, mathematics, and attendance. It used an integrated administrative data system to create a combined data set of risks (i.e., birth risks, teen mother, low maternal education, homelessness, maltreatment, and lead exposure) for…

Eighty to ninety percent of e-mail is considered unsolicited commercial communication, or spam. Not only does spam violate the privacy of users, but it also incurs societal costs associated with time-related losses, serves as a vehicle for cyber-crime, and threatens the success of e-commerce by lowering consumer confidence. This quantitative…
