Computer-aided tool for the teaching of relational algebra in data base courses

This article describes the design and implementation of computer-aided tool called Relational Algebra Translator (RAT) in data base courses, for the teaching of relational algebra. There was a problem when introducing the relational algebra topic in the course EIF 211 Design and Implementation of Databases, which belongs to the career of Engineering in Information Systems of the National University of Costa Rica, because students attending this course were lacking profound mathematical knowledge, which led to a learning problem, being this an important subject to understand what the data bases search and request do RAT comes along to enhance the teaching-learning process.It introduces the architectural and design principles required for its implementation, such as: the language symbol table, the gramatical rules and the basic algorithms that RAT uses to translate from relational algebra to SQL language. This tool has been used for one periods and has demonstrated to be effective in the learning-teaching process.  This urged investigators to publish it in the web site: www.slinfo.una.ac.cr in order for this tool to be used in other university courses.

Reflexiones onomasiológicas en torno al papel de la administración en los programas de Español como lengua extranjera

Es un planteo de base teórica sobre la incorporación efectiva de la conciencia intercultural en los programas de Español como lengua extranjera (ELE) y de la influencia de las personas encargadas de administrar y facilitar su adecuada inclusión. La competencia en una lengua extranjera supone tanto capacidades lingüísticas, como el conocimiento y apropiación del conjunto de valores, creencias y normas culturales que conforman la identidad individual y colectiva de una comunidad académica.This is a theoreticalIy-based proposal conceming the effective incorporation of intercultural awareness in Spanish as a Foreign Language (SFL) programs and the influence of administering facilitating its adequate inclusion. Proficiency in a foreign language involves not only linguistic skills but also a knowledge and appropriation of the cultural values, beliefs and norms integrated in the individual and collective identity of an academic community.
