In this study, the relationship between study preservice science teachers' academic procrastination and their attitudes toward social media was investigated. The study was carried out with the participation of 511 preservice science teachers (F: 346, M:165) on teacher education course at Dicle University during 2014-2015 academic year. The date…

Eta squared measures the proportion of the total variance in a dependent variable that is associated with the membership of different groups defined by an independent variable. Partial eta squared is a similar measure in which the effects of other independent variables and interactions are partialled out. The development of these measures is…

This causal comparative study used a set of predictable variables, including school configurations, to predict student proficiency on the Arizona Instrument to Measure Standards (AIMS) test in reading and math. The school configurations were K-8 and middle school. The researcher analyzed the 2011-2012 AIMS reading and math achievement scores of…

This paper uses social network analysis to evaluate how the formation of an interdisciplinary brain research institute affected interaction and collaboration among neuroscientists at one Canadian university. The research institute, formed in 2004, has about 100 members representing ten different departments across the university campus. We…

The purpose of this study was to gain a stronger understanding of the characteristics that influence membership levels at dues-based alumni associations serving public universities. Prior studies have demonstrated that alumni association members are more likely to give to their institutions; and their gifts, on average, are larger than those of…

Even though the number of African American students has increased on college campuses, particularly Predominately White Institutions (PWIs), over the last century, they are less likely to graduate than their White counterparts are. They face discrimination, hostile environments, adversity, low or no social or mentoring support, and often feel…

A method for comparing the cross-validated classification accuracies of predictive discriminant analysis and logistic regression classification models is presented under varying data conditions for the two-group classification problem. With this method, separate-group, as well as total-sample proportions of the correct classifications, can be…

A study examined differences in motivations between fundamental Christians and atheists on the Reiss Profile of Fundamental Goals and Motivational Sensitivities. Only five of the 15 areas measured by the Reiss Profile were used in the study. The hypothesis was that (within these areas: (1) independence, (2) power, (3) vengeance, (4) status, and…

This study involved two phases: first when classification was based on the calibration sample, and second in a cross-validation setting. Computer-generated data were used. Results obtained from rules based on probabilities of group membership were compared for accuracy when classifying in the discriminant space and in the predictor variable…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
