An alternative approach for introducing instrumental variables in econometrics courses is presented in this article. The method is based on the ordinary least squares omitted variable bias formula. The intuition for the approach capitalizes on students' understanding and intuition of omitted variables. Thus, if students understand omitted variable…

Within psychology and the social sciences, Ordinary Least Squares (OLS) regression is one of the most popular techniques for data analysis. In order to ensure the inferences from the use of this method are appropriate, several assumptions must be satisfied, including the one of constant error variance (i.e. homoskedasticity). Most of the training…

Percentage of body fat, age, weight, height, and 14 circumference measurements (e.g., waist) are given for 184 women aged 18-25. Body fat, one measure of health, was accurately determined by an underwater weighing technique which requires special equipment and training of the individuals conducting the process. Modeling body fat percentage using…

The ability to understand and incorporate other perspectives into one's own perspective is an important overarching outcome of higher education and a necessary precursor for the development of most higher-order learning outcomes. Utilizing a multi-institutional survey of 21,548 college seniors, we examined background characteristics and…

Education researchers often study count variables, such as times a student reached a goal, discipline referrals, and absences. Most researchers that study these variables use typical regression methods (i.e., ordinary least-squares) either with or without transforming the count variables. In either case, using typical regression for count data can…

The purpose of this study was to compare differences in the quality of professional development between U.S. music educators and teachers of other disciplines. Data were drawn from the 2011-2012 Schools and Staffing Survey. Factors such as types of professional development, quantity of activities, and levels of satisfaction were analyzed through a…

Students' educational motivation is significant for performance and achieving learning, but little is known about what fuels such motivation. Educational motivation is regarded as the drive and inner state that energise educational activities, facilitate learning and channel behaviour towards achieving educational goals. Educational motivation…

Despite considerable research on student retention and persistence, college graduation rates remain modest. This article proposes the concept of student identity centrality, which is defined as the extent to which being a student is important to one's self-image or identity. This study found student identity centrality was positively related to…

Purpose: The purpose of this paper is to examine the effects of organizational-related variables and the moderating role of career strategies on protean career among employees. Design/methodology/approach: Research data are gathered from a sample of 306 employees in 18 electrical and electronics multinational corporations (MNCs) in Malaysia.…

The role of gender, race/ethnicity, and disability category in the relationship between student perceptions of family support of personal growth and school facilitation of student involvement and the development of self-determination was examined in a sample of 190 diverse high school students with disabilities. Results indicated that both school…

This study analyses the effects of school resources on student mathematics achievement in Zimbabwe using a 3-Level Hierarchical Linear Model (HLM). The major findings of the research are that a teacher trained in the relevant subject, class size, having a highly qualified school head and having a generally high resource endowment at school level…

We review the effectiveness of first-year seminars based on the widely used criteria of first-year grades and the 1-year retention rate. Meta-analytic results indicate that first-year seminars have a small average effect on both first-year grades (k = 89, N = 52,406, d = 0.02) and the 1-year retention rate (k = 195, N = 169,666, d = 0.11). We…

Comparisons of grade based learning outcomes between online and face-to-face course formats have become essential because the number of online courses, online programs and institutional student enrollments have seen rapid growth in recent years. Overall, online education is largely viewed by education professionals as being equivalent to…

Analyzing data that possess some form of nesting is often challenging for applied researchers or district staff who are involved in or in charge of conducting data analyses. This report provides a description of the challenges for analyzing nested data and provides a primer of how multilevel regression modeling may be used to resolve these…

Early detection of reading problems is important to prevent an enduring lag in reading skills. We studied the relationship between speed of word recognition (after six months of grade 1 education) and four kindergarten pre-literacy skills: letter knowledge, phonological awareness and naming speed for both digits and letters. Our sample consisted…
