Contributing to the OER movement: A practical experience
(IEEE, 2017) Mora Rivera, Sonia; Coto, Mayela
Open educational resources (OER) propose a culture of sharing to make knowledge a good for humanity. The educational field recognizes the potential of OER to expand access to education and the Information and Communication Technologies (ICT) provide the context for sharing, using and reusing this knowledge. In addition, the OER movement offers scholars the opportunity to rethink their educational practice. Although the literature has shown that academics in general have the practice of sharing their educational resources with close colleagues, it is also true that open and large-scale exchange through appropriate licensing and institutional repositories is an emergent move in many universities. This paper presents an exploratory study to promote, among academics and students, their participation in the OER movement. The experience allowed to generate knowledge on the subject, to develop and validate a set of educational resources to later create in the institutional repository the first OER community.

Disciplinary and Generic Abilities in PBL: A Study of Life Stories from the Gender Perspective in Systems Engineering Education
(University of Brasilia, 2018) Sandoval-Carvajal, Maria-Marta; Lizano Madriz, Fulvio; Porras Piedra, Elena; Cortés Chavarría, Rita
While it is true that socio-economic environment plays a determining role in terms of gender and entry into technological careers such as systems engineering, tendency to generate generic and disciplinary competencies from the gender point of view, is also something relevant to analyze specific actions that allow curricular changes in curricula. Recent studies show a reduction in the entry of women into systems engineering careers since several years ago. Some of these studies suggest, among other things, aspects of socio-economic perception to explain this phenomenon. In this research we want to offer a new angle of debate focused on the results of the training process by using PBL case of study in Systems Engineering grade. We were interested in exploring the generation of competencies by gender. The Tuning Latin America project, which was originated in its European counterpart, represented an effort to locate generic and disciplinary competencies of computer science practitioners with the participation of 14 universities in the region. In this study we explore the state of internalization of disciplinary and generic skills in systems engineering students based on their life histories by considering the gender perspective. The main research method used was content analysis of approximately 150 life histories of systems engineering students. Previously, a set of disciplinary and generic skills was defined based on the classification of such skills included in the Tuning Latin America project. Interviews and focus groups sessions were also used in order to validate information. The results indicate several interesting aspects. The main competence identified by men is the disciplinary competence "Apply knowledge of computer science" and for women it was a generic competence called “the teamwork ability”. The results also show evidence that the PBL and management by competencies can help visibility of competencies something that regular Systems Engineering students would not consider, especially in the case of men, who in spite of consider first some disciplinary competences, they tend to put other generic competencies in second place. This aspect, which seems not related to gender stereotypes, could also be other attractive factor to motivate women to enter Systems Engineering education. Finally, this study not only points out the differences, but also the common elements in the teaching-learning process of engineering, such as the balance between both groups of competencies. Both male and female students using the PBL and a competencies approach, show the importance of a balance between technical and generic skills, a situation that guarantees job and social integration for future professionals.

Implementación de una infraestructura de microservicios con contenedores
(Editorial Universidad Nacional de Alcalá, 2019) Calvo Suárez, Jose Pablo
La arquitectura de microservicios es un enfoque de desarrollo de software moderno que permite diseñar aplicaciones en la que cada componente, denominado servicio, se desarrolla e implementa de manera independiente, en lugar de utilizar un patrón monolítico. Estos servicios se encuentran interconectados entre sí, aunque cada uno opera de forma separada, lo que implica que en el caso de fallo de alguno de los módulos no se afecte la operación de otros componentes de la aplicación. Una de las tecnologías utilizadas en este tipo de infraestructura son los contenedores, que agrupan un conjunto de herramientas necesarias para proporcionar un ambiente de ejecución adecuado para las aplicaciones.
Introducción al manejo de sistemas de control de versiones con Git y Github
(Editorial Universidad Nacional de Alcalá, 2019) Calvo Suárez, Jose Pablo
Los sistemas de control de versiones (VCS por sus siglas en inglés) se utilizan ampliamente en diversos proyectos de desarrollo de software en la actualidad, debido a su flexibilidad, escalabilidad, potencia y facilidad de uso. En la actualidad, tanto proyectos de software libre como propietario se administran a través de estas herramientas para mantener diversos tipos de aplicaciones, desde pequeños scripts de automatización y páginas web, hasta proyectos de Internet de las Cosas, Ciencias de Datos, Inteligencia Artificial, entre otros. Por lo tanto, es muy importante para los programadores aprender a interactuar con estos sistemas.
PBL en carreras de Ingeniería de Sistemas: una perspectiva Bottom - Up
(Aalborg University Press, 2015) Sandoval-Carvajal, Maria-Marta; Cortés Chavarría, Rita; Lizano Madriz, Fulvio
La academia enfrenta cada día más retos relacionados con el desarrollo de competencias de los estudiantes. La implementación de filosofías de aprendizaje como el PBL (Problem Based Learning) representa un esfuerzo iniciado con apoyo de los niveles superiores en las universidades (Top-down), o desde niveles operativos (bottom-up). Este artículo describe la implementación de la filosofía PBL desde una perspectiva bottom-up, en la Universidad Nacional (UNA), Costa Rica. La implementación específica inició en 2008 en los cursos de Ingeniería de Sistemas. En esta implementación, varias habilidades técnicas y blandas fueron integradas considerando una estrecha colaboración con la industria. En este contexto, los estudiantes lideran técnicamente un proyecto de desarrollo de software en una empresa real. Entre otras cosas, la implementación de PBL incluyó diferentes técnicas tales como sensibilización, autocapacitación, análisis comparativos de la teoría y la práctica, así como asesorías formales e informales. Para medir el impacto de esta implementación, hemos conducido un estudio de encuesta con la participación de estudiantes, egresados y representantes de la industria. Los resultados del estudio sugieren que una iniciativa de implementación del PBL desde el nivel jerárquico más bajo, es percibida como una experiencia beneficiosa para las empresas. Adicionalmente, los estudiantes y egresados sienten que han aprendido más y al mismo tiempo, contribuyen al desarrollo del país. El desarrollo de los proyectos universidad – industria y el proceso de aprendizaje, empoderan a los estudiantes, retroalimentan las mejoras a los planes de estudio, facilitan el proceso de aprendizaje a través del contacto con una organización y contribuyen al desarrollo de las organizaciones.
PBL in Systems Engineering Education: the Students’ Perspective
(PAEE association, 2015) Cortés Chavarría, Rita; Sandoval-Carvajal, Maria-Marta; Lizano Madriz, Fulvio
Assessment of educational innovation efforts must be integral. Among other, it is necessary to consider students' perspective on the impact of educational innovation in their formation. This becomes even more critical if educational innovation efforts include the use of a model like the Problem Based Learning. This paper presents the results of a survey study made in a context where problems take form of software development projects, made by systems engineering students in real contexts. The study aims to measure the impact of the implementation of the PBL model in the formative process of system engineering students. The study was conducted by considering regular students of the National University (UNA) in Costa Rica. Data collection was face to face with the students and measured various aspects of the students’ perspective on the educational model. Results suggest a high motivation and a positive effect on students. Their willingness to learn, apply knowledge and develop their skills in developing real software engineering projects, was identified as relevant results of the educative process. Student's satisfaction is evidenced by the achievement obtained to complete the project and implement the software. The assessment of the skills varied throughout the educative process. However, aspects as the project management, leadership, and team work maintain a high valuation and are fundamental pillars for the implementation of the development methodology used during courses.

Social Media and Enderly people: Research Trends
(Springer, 2017-05) Coto, Mayela; Lizano Madriz, Fulvio; Mora, Sonia; Fuentes Bustos, Jennifer
Population aging is now a global reality a global reality, and interaction with social media as well. The older adult population is increasing significantly and their mental and physical health will be a worldwide priority. Social networks have been seen as an important ally to support older people. It is therefore important to know how the elderly population interacts with social media and the potential benefits and dangers in this interaction. This paper reports the results of a systematic literature review in the field of social media and the elderly. The analysis of the research papers focused on their research approach, methods of data collection, research domains, objectives and results. Our findings indicate that currently there is no predominant research approach for this field of study, samples are generally very small, research efforts are focused on specific domains, and there is a lacking of rigor in the reporting process. This work is important because it identifies the current state of research in this field and guides new potential research.
Supply and Demand of Human Resources in Computer Sciences in Costa Rica For Whom the Bell Tolls
(Infonomics Society, 2018) Mata, Francisco J.; Quesada Rosales, Ariella
We analyze in this paper the supply and demand of human resources in computer sciences (CS) in Costa Rica. This is done with the aim of validating claims made by the local media about a large deficit of professionals for ICT occupations in this country, in part due to the lack of response of public universities to the needs of the labor market. For this reason, we also analyze the contribution of the universities in the country, in general and considering separately public and private universities. On the supply side, we studied the supply of degrees for the 2001-2013 period. Among the major findings of our study was an increase in the number of university graduates in CS, which is greater than the increase in the total number of academic degrees awarded. This provides evidence that universities in the country are responding positively to the labor market. Furthermore, we found that public universities shared a greater burden in supplying such degrees, considering their smaller number. Furthermore, we found that the structure of degrees awarded by knowledge areas is very similar among these two types of universities, favoring both degrees in social sciences and education, over engineering and basic sciences –areas within CS is contained. Such a finding undermines the criticism that public universities, due to their bureaucratic processes, are not capable of responding to the needs of the labor market. On the demand side, we found that the expected demand for the period 2014-2016–using the available data– does not seem to exceed the supply, not providing evidence about the existence of a large deficit, as claimed by local media. However, limitations in the demand data obtained, as well as methodological limitations for measuring the gap between supply and demand, may be affecting this result. These limitations are discussed and solutions to overcome them are presented.

To what extent are faculty ready to participate in the OER movement? The case of the Informatics School, UNA
(Sociedad Argentina de Informática e Investigación Operativa (SADIO), 2017-09) Coto, Mayela; Mora Rivera, Sonia
The success and sustainability of the Open Educational Resources (OER) movement depends to a large extent on large-scale participation in the use and production of educational resources. The aim of this paper was to explore faculty staff knowledge and behaviors about OER with a focus on resource sharing attitudes. The study was conducted at the School of Informatics of the National University of Costa Rica. Faculty were invited to respond to a questionnaire. The respondents indicated being open to the idea of sharing their own content and, as in other studies, demonstrated existing practices of sharing resources among their colleagues at the local level. However, there is little knowledge about OER and CC licenses, as well as concern about intellectual property rights, factors that hinder their participation in the movement.
