The present study aimed to investigate the interaction among grade dropping and reflective thinking abilities of the participants and to also check if action research enhances learners’ reflective thinking. A cyclic action research was run for 8 sessions. Kember et al.’s (2010) reflective thinking questionnaire and three in-term quizzes were administered. Students also made questions based on t...

We discuss an analysis pattern for the management of student courses. The pattern describes events such as student registering in course sections, student adding and dropping course sections, grade management, etc. The pattern corresponds to a minimal semantic unit, applicable to a variety of situations. This is a composite pattern that includes two simpler patterns that describe course registr...

The aim of this investigation is to provide a comprehensive review of dropout research that examines grade retention within both associative and predictive models. A systematic review of seventeen studies examining dropping out of high school prior to graduation demonstrates that grade retention is one of the most powerful predictors of dropout status. The discussion addresses the discrepancies...

ROC Curves (Receiver Operating Characteristic) are remarkably useful in medical decision-making. Given a common measurable characteristic, with a continuous output in all the beings of a group, ROC curves determine a threshold on the values of the characteristic, which tries to predict the classification of beings into discrete classes. In the Facultad de Informática of Valencia (Spain), we hav...

The academic performance of students in grades 9-12 who did or did not participate in high school sports in Kansas during the 2008-2009 school year was analyzed. In addition to overall comparisons between athletes and non-athletes on GPAs, graduation rates, number of dropouts, ACT test scores, and state assessments, some gender, ethnicity, and grade comparisons were made. High school athletes e...

The effects of interference threshold and SNR acceptance threshold on channel capacity have been determined for several distributed channel assignment algorithms using Unsupervised FDMA (UFDMA), a multiple access scheme for the terrestrial radio environment. It is found that the effect of tightening the interference threshold reduces the call dropping probability at the expense of increasing th...
