Quantitative models and software architecture, facing student Desertion and Permanence
The development of multi-tier architecture based on knowledge and model driven for the competitiveness is discussed in Higher Education; the engine are Mathematical and Computational Models for dynamic and structural analysis of the academic governance given the student high dropout. The problem is characterized by the high social and economic costs; the layers mentioned, mainly are: Institution issues, Users (3-student levels, Faculty Teachers and Parents) and the data and knowledge, enabling management of multiple piece inter-connected environments, focusing on the governance with its sustainability impact into quality, productivity and competitiveness. Data architecture gives several figures on desertion, costs (families, institutions). The period of observation, the student's retention figures were increased significantly and the desertion control was also improved.
Handbook on Enterprise Architecture
This handbook is about methods, tools and examples of how to architect an enterprise through considering all life cycle aspects of Enterprise Entities.Itis based on ISO15704:2000, or the GERAM Framework.A wideaudience is addressed, as the handbook covers methods and tools necessary to design or redesign enterprises, as well as those necessary to structure the implementation into manageable projects.
Current issues with assessment formats and interoperability
Assessment has been one of the areas in computer supported learning where technology has been quickly deployed. Support for computer based assessment is found not only in all Learning Management Systems, but also as stand-alone tools. This large number of tools has led to the appearance of a large number of formats to store, retrieve and exchange assessment material. Although institutions such as the IMS Global Consortium have proposed specifications (e.g. IMS QTI) aimed to facilitate the exchange of this material, in the actual landscape, there are still too many formats that significantly hinder the reuse of this material. In this paper an analysis of the implementation of these formats is described.
