Recent efforts in the area of learning technology have resulted in a considerable improvement in the interoperability of digital education resources. On the basis of sharing and integration of digital educational resources, knowledge Processing and service considers the Semantic knowledge extraction of metadata of educational resources, Construction ontology for educational resources, and combi...

This work puts under the judgment and speculation of the educational community, the concept of the educational digital entity, that is the digital representation of the teacher or as a virtual figure with human characteristics. With the help of three dimensional graphics and advanced animation techniques, the digital entity will have (?) the possibility to imitate or to substitute the a teacher...

This paper presents a case study on the transition of a model-driven software development process, from an educational environment, to a laboratory that develops real life information systems. Although this laboratory, named Synergia, is internally organized as a traditional software development company, it also retains important academic characteristics. Synergia uses the Praxis software devel...

Using 25 years of data on individuals spanning the entire developmental horizon from birth until adulthood drawn from the Panel Study of Income Dynamics (PSID), this study models educational attainment in a duration framework to examine the long-term effects of parental divorce and its timing on child educational attainment. Controlling for both preand post-divorce family characteristics and un...

Cloud Computing is a new application model for decentralized computing which can provide reliable, customized and maximum number of users with minimum resource. The development of cloud computing marks a great leap towards designing a unified, open and flexible educational information platform, sharing educational resources, and diminishing gaps in the use of educational information. This paper...

This study proposes and illustrates a two-stage strategy to analyze differential item functioning in comparative educational studies. At the first stage, within each country, item difficulties are estimated. At the second stage, results are combined across countries using a meta-analytic framework to investigate (a) whether the items function consistently at the country level, and (b) what coun...

Recent developments on mobile devices and networks enable new opportunities for mobile learning anywhere, anytime. Furthermore, recent advances on adaptive learning establish the foundations for personalized learning adapted to the characteristics of each individual learner. A mobile learner would perform an educational activity using the infrastructure (e.g. handheld devices, networks) in an e...

The educational attainment of participants in the Chicago Longitudinal Study (93% Black and 7% Hispanic) was examined. Cluster analysis on measures of human capital resources, family dynamics and demographics was used to identify four distinct profiles of families. In general, children who had family profiles characterized by higher levels of human capital resources and more favorable scores on...

This study explicitly considers that education is a multi-input multi-output production process subject to inefficient behaviors that can be identified at student level. Therefore a distance function allows us to calculate different aspects of educational technology. The paper presents an empirical application of this model using Spanish data from the Programme for International Student Assessm...

Nowadays there are a large amount of virtual libraries and repositories of resources, where people can access and great variety of information in multiple fields of knowledge. One of these types of data is Learning Objects (LOs), which contain metadata to locate and recover them, according to the specific educational needs of users. Educational objectives are clearly oriented to skills developm...
