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.

Strategies to Promote Research and Logical Reasoning in the Teaching of Mathematics in the Schools

The purpose of this paper is to raise a debate on the urgent need for teachers to generate innovative situations in the teaching-learning process, in the field of Mathematics, as a way for students to develop logical reasoning and research skills applicable to everyday situations. It includes some statistical data and possible reasons for the poor performance and dissatisfaction of students towards Mathematics. Since teachers are called to offer meaningful and functional learning experiences to students, in order to promote the pleasure of learning, teacher training should include experiences that can be put into practice by teachers in the education centers. This paper includes a work proposal for Mathematics Teaching to generate discussion, curiosity and logical reasoning in students, together with the Mathematical problem solving study.

Contributions of Neuroscience to Develop Teaching Strategies and Learning of Mathematics

The goal of the present work is to develop some strategies based on research in neurosciences that contribute to the teaching and learning of mathematics. The interrelationship of education with the brain, as well as the relationship of cerebral structures with mathematical thinking was discussed. Strategies were developed taking into consideration levels that include cognitive, semiotic, language, affect and the overcoming of phobias to the subject. The fundamental conclusion was the imperative educational requirement in the near future of a new teacher, whose pedagogic formation must include the knowledge on the cerebral function, its structures and its implications to education, as well as a change in pedagogy and curricular structure in the teaching of mathematics.

MEDIA IN THE ERA OF GLOBALIZATION IN LATIN AMERICA

Terms like Internet, cyberspace, virtual reality, in short, globalization, have been frequently words for all of us, in recent years. This refers to the phenomenon that has shaken the people of this world. Are rapidly changing due to technological advances and complex levels reaching relations between countries, corporations, partnerships and people.The attempt to understand the phenomenon of globalization is compounded when we try to understand the term, coined by Marshall McLuhan.McLuhan was born in Edmonton, Alberta, Canada and studied at the Universities of Manitoba and Cambridge, the latter of which he received his degree of Doctor of Philosophy specializing in English Literature. He taught at the universities of Wisconsin and St. Louis and University of the Assumption and Saint Michael's College, University of Toronto, where he was director of the Center for Culture and Technology.Marshall McLuhan and B. R. Powers, wrote the play, The Village Global1. The universe has become a village is the future predicted for them in the 60's. Today reality has overtaken the theory. However, this phenomenon is presented in this work, so whimsical style reminiscent of Jules Verne, but does not clarify the content of the term. While we believe that in the past there were attempts; globalize these attempts were very different from what we understand by globalization. 

Research on the BEIC Curriculum: Unveiling What Lies Under the Tip of the Iceberg

Es un detenido análisis de la investigación The Value of Curricular lntrospection, en que se incorpora la realimentación dada por diversos participantes nacionales y extranjeros en el CILAP 2007, a quienes se les expuso los resultados iniciales de esta investigación. El estudio surgió de la disparidad de criterios entre diversos actores del BEIC, de la ELCL, respecto a la pertinencia que para la enseñanza del inglés a niños en Costa Rica tienen los principios comunicativos denominados interacción, inmersión parcial y aprendizaje por experiencia. Así, mientras diseñadores de currículo y profesores del BEIC consideraban estos principios altamente eficaces, buena parte del estudiantado que realizaba la práctica docente pensaba lo contrario.A detailed analysis is provided here of the research project titled The Value of Curricular Introspection. It also includes the feedback given by the national and foreign participants in CILAP 2007, to whom this study was presented. The investigation emerged from the diverse opinions existing among BEIC-ELCL actors regarding the pertinence of interaction, partial immersion and experiential learning communicative principies for the teaching of English to children in Costa Rica. Thus, whereas BEIC curriculum designers and professors considered these principies to be highly effective, many student-teachers in that program believe just the opposite.

Teaching Communications, Cultures, Connections, Comparisons, and Communities with Multimedia: A University-Middle School Service-Learning Project

Se describe el uso de tecnología en forma de presentaciones de multimedia para facilitar la enseñanza de las Normas para el Aprendizaje de una Lengua Extranjera del Concilio Americano para la Enseñanza de Lenguas extranjeras. Las normas abarcan las comunicaciones, las culturas, las conexiones, las comparaciones y las comunidades. El estudiantado universitario aprende a crear, con multimedia, presentaciones sobre un tema cultural en la lengua meta. El componente de aprendizaje por servicio comunitario se fundamenta en las presentaciones creadas para estudiantes de colegio, quienes tienen acceso a las presentaciones en un sitio web de la universidad.A description is provided of how the use of technology in the form of multimedia presentations enhances the teaching of the Five C Standards for Foreign Language Learning of the American Council on the Teaching of Foreign Languages: communications, cultures, connections, comparisons, and communities. University students learn to create multimedia presentations on a cultural topic in the target language. The service-learning component provides the multimedia presentations for middle-school students who access them from the university website.

Factors Contributing to the Academic Performance of BEI Learners

Se analizan los factores que intervienen en el rendimiento académico de los estudiantes del Bachillerato en la Enseñanza del Inglés (BEI) de la Universidad Nacional (Costa Rica). El contexto universitario, el papel de los profesores, la motivación en los estudiantes y los hábitos de estudio son condiciones para fomentar el éxito académico. Según los resultados, los aprendientes necesitan ciertas características personales, motivación y metas para tener éxito en su trabajo académico. Este estudio de caso contribuye a una mejor percepción de los factores que influyen en el mejoramiento de las aptitudes de estudio y aprendizaje, así como los que intervienen en el logro de las metas académicas.This analysis refers to factors contributing to the academic performance of the students majoring in the teaching of English at the Universidad Nacional (Costa Rica). The university context, the professors' role, students' motivation and their study habits are conditions for fostering academic success. The findings indicate that learners need certain personality traits, motivation and goals to succeed in their academic work. This case study provides insight on the factors that influence the enhancement of study skills and leaming, as well as other factors that contribute to the accomplishment of academic goals.
