In virtual environments it also guides teachers as to the effectiveness of their activity and academic officers as to the system for teaching appraisa...
A common problem in schools teaching languages is the preliminary assessment of students' knowledge to assign a skill level in the language that they would like to learn. Normally, level tests consist of an oral test, a written test and a listening test. All these tests can be performed through from a remote location, though the written test is les...
Information and materials on practically any topic can be currently found on the Internet. However, the advances to classify and measure the quality of materials have been minimal and scattered. Anyone can create materials and publish them, but no one ensures or guarantees that those materials will be accessible or their contents will be suitable f...
The goal of this invited editorial is to introduce an IEEE-RITA special issue on trends in computers in education. The special issue integrates the thoroughly revised and extended versions of five outstanding papers presented at the 16th International Symposium on Computers in Education (SIIE'14), held in La Rioja in November 2014.
In addition to formal courses, higher education usually involves other non-formal activities, such as seminars, workshops, and conferences. Many times, there is a lack of institutional support for managing these activities, so the organizers are responsible for such management, which implies a significant extra effort. In this paper, we describe a...
The Big Data phenomenon has multiple perspectives, such as the development of new types of databases, the processing of data and data visualization.

Model transformation is a key aspect of model-driven software development because it enables the automatic derivation of different interpretations of a system model. In many scenarios (e.g., design of domain-specific languages), models usually have implicit identifiable primary tree-like syntactic structures, on which additional secondary relations...
At university levels, there are regular courses and also there are other unregulated teaching activities such as seminars, workshops and conferences. In most of the cases there is no institutional support for managing this type of activities, and this responsibility relies on the organizers. An example of this type of activity is the workshop Zarag...

This paper describes the grammatical approach, an approach to the specification of XML processing tasks based on attribute grammars. This approach describes how to provide task-specific context-free grammars for XML documents, as well as how to decompose complex processing tasks into simpler ones with attribute-grammar fragments. The result is a hi...
This paper describes how to use conventional parser generation tools for the development of JSON processing applications. According to the resulting grammar-driven development approach, JSON processing applications are architected as syntax-directed translators. Thus, the core part of these components can be described in terms of translation schema...
This article describes structure-preserving coding patterns to code arbitrary non-circular attribute grammars as syntax-directed translation schemes for bottom-up and top-down parser generation tools. In these translation schemes, semantic actions are written in terms of a small repertory of primitive attribution operations. By providing alternativ...
This paper describes how to use conventional compiler construction tools, and parser generators in particular, to build XML-driven application generators. In our approach, the document interface is provided by a standard stream-oriented XML processing framework (e.g., SAX or StAX). This framework is used to program a generic, customizable XML scann...
