In this study, I examined the relationship that exists among school belonging, achievement motivation, and academic achievement in a sample of student-athletes at UC Berkeley. The goal of the study was to achieve a deeper understanding of how and why achievement motivation and academic achievement is often discrepant between revenue and…

The benefits of college education are extensive. In addition to the obvious cognitive advantages, those who obtain a college education experience economic, health, family and neighborhood benefits. These benefits are felt not only within the generation of the individual who completed their degree; but inter-generationally as well. The ability to…

This study examined the effect of explicit and engaging supplemental early literacy instruction on at-risk kindergarten children's literacy development. Sixty-three kindergarten-aged children who had been ranked in the lowest 20th percentile on basic literacy skills participated in this study (38 treatment). Results reveal that children who…

Using data from a self-report survey of juniors and seniors, we document statistically significant growth of a student engagement culture on our campus after a three year period following implementation of an institutional Quality Enhancement Plan. Twenty-three of 45 individual variables, scores on four of 10 multivariate engagement factors, and…

Extant research has primarily assessed the quality of the American school experience for immigrant students by focusing on performance-based outcomes (e.g., grade point average [GPA]). Unlike such research, the current study examines the impact of generational status and language proficiency on Latino and Asian students' (n = 2,261) attitudes…

To investigate the generalizability of the results of single-case experimental studies, evaluating the effect of one or more treatments, in applied research various simultaneous and sequential replication strategies are used. We discuss one approach for aggregating the results for single-cases: the use of hierarchical linear models. This approach…

Given that a minor condition holds (e.g., the number of variables is greater than the number of clusters), a nontrivial lower bound for the sum-of-squares error criterion in K-means clustering is derived. By calculating the lower bound for several different situations, a method is developed to determine the adequacy of cluster solution based on…

Stressful and positive family caregiving experiences were examined as predictors of caregivers' patterns of positive and negative affect in a sample of families providing care for a relative with dementia (N = 234). Four affect pattern groups were identified: (a) Well Adjusted (i.e., high positive affect, low negative affect); (b) Ambiguous (i.e.,…

Although many researchers are familiar with "testwise" alpha, "experimentwise" Type I error rates are also important and must be considered in many research situations. Experimentwise error rates can inflate rapidly when researchers use multiple univariate tests. Both analysis of variance (ANOVA) post hoc and multi-variate…

Discriminant analysis is a multivariate method of analysis with two purposes: (1) to describe differences among groups; or (2) to classify participants into groups. Either linear or quadratic rules can be used in both descriptive discriminant analysis (DDA) and predictive discriminant analysis (PDA). In both DDA and PDA the researcher wants to use…

A simplified mathematical and computational treatment of the canonical correlational analysis of two-way contingency tables is provided. (Author)

The "International Society for the Social Studies (ISSS) Annual Conference Proceedings" is a peer-reviewed professional publication published once a year following the annual conference. The following papers are included in the 2015 proceedings: (1) Local History and Local Culture at the Core of Elementary Social Studies Curriculum (C.…

Introduction: The goal of this study is to expand our understanding of the relationships between selected tasks, cognitive abilities and search result interfaces. The underlying objective is to understand how to select search results presentation for tasks and user contexts Method: Twenty three participants conducted four search tasks of two types…

Little is known about what factors adolescent males consider important when making decisions concerning the resolution of an unplanned pregnancy with a teenage partner. Young men's influence on pregnancy outcome decisions can play an important part in the subsequent psychological adjustment of the female. The present report draws on data from a…

This empirical study explores the nature of and profiles in primary teachers' educational beliefs in the Chinese educational settings. A survey of 820 primary school teachers was conducted using a questionnaire focusing on teachers' traditional and constructivist beliefs about teaching and learning. Analysis of variance and cluster analysis were…
