A prospective cohort study compared educational and employment outcomes among 91 middle-class white boys, 6 to 12 years of age, with ADHD who were referred to a psychiatric clinic with outcomes for 96 matched controls. Investigators used multiple educational achievement tests to evaluate participants when they enrolled in the study, then administered educational and occupational questionnaires ...

This paper investigates interaction of users with multiple agents in the context of web-based implicit communities of learners. In particular a user-centred quality-of-content control mechanism is presented, inspired by social protocols of interaction, which is used for building and maintaining cohesion of such communities. This takes the form of an innovative algorithm for ranking offers of ed...

poland is a traditional mining country ranking high in europian mining. a considerable part of polish national-gross-product comes from mineral resources. a large number of the working people work in the mines and related industry. research and educational centers depending on mining are well grown and are of great importance. the major mining commodities of poland are: coal, brown coal copper,...

We present our overall third ranking solution for the KDD Cup 2010 on educational data mining. The goal of the competition was to predict a student’s ability to answer questions correctly, based on historic results. In our approach we use an ensemble of collaborative filtering techniques, as used in the field of recommender systems and adopt them to fit the needs of the competition. The ensembl...

Many states and school districts have adopted Value-Added Models (VAMs) as part of educational accountability systems. The goal of these models, which are also referred to as Value-Added Assessment (VAA) Models, is to estimate effects of individual teachers or schools on student achievement while accounting for differences in student background. VAMs are increasingly promoted or mandated as a c...

Statistics from top world University and higher educational institution ranking agencies including Cybermetrics Lab reveal Ghanaian universities relatively low among their African counterparts in particular the at large. To understand this trend of occurrence an online survey was conducted for depth study methodology to help create awareness strategies can adopt improve positions. This study, w...

The purpose of this article is to introduce a new scheme for robust multivariate ranking by making use of a not so familiar notion called monotonicity. Under this scheme, as in the case of classical outward ranking, we get an increasing sequence of regions diverging away from a central region (may be a single point) as nucleus. The nuclear region may be deened as the median region.

Introduction. The pressure on universities worldwide has increased to transform themselves from isolated educational institutions to profit-generating businesses. The visibility of a Web page plays a role in attracting potential clients, as more and more young users are depending on the Web for their everyday information needs. One of the purposes of this study was to evaluate the visibility of...

We propose a new computational method to support learning that relies on adaptive exploration of the shortest paths in conceptual networks that have been formed based on cooccurrences of concepts in suitable text samples and selecting concepts corresponding to desired language ability levels and frequency ranking. Relying on Google Web 1T 5-gram database we have built a conceptual co-occurrence...
