    Análisis, diseño e implementación de un componente de software que soporte el método Dharma
    (2015) Pesántez Mosquera, Andrés Israel; Carvallo Vega, Juan Pablo
    The present study analyzes, develops and implements a software component that brings a support the different activities of DHARMA (Discovering Hybrid Architectures by Modelling Actors) method. The incorporation of this component has the finality of brings to the software analysts a function serial that let them use the four activities of DRHAMA method based in i* models in an easy way. The component will be available in a web page therefore the analysts can use it with an Internet connection and a web navigator. The utility of this component is considerable, because it lets users to apply the DHARMA method to many organizations at the same environment of work. The analysts can reuse the information of the organizations and simplify the work when they want to model a new organization. The software component also lets the group work, so many analysts can model one organization at the same time. All this in an easy and simple way of model organizations, optimizing the work of the analysts.

    Evaluación de la calidad de los MOOC con ISO/IEC 25010
    (2017) Sánchez Peralta, Malhena de Lourdes; Carvallo Vega, Juan Pablo
    MOOC or Massive Open Online Course is a virtual training form present in the current educational landscape. Several authors raise doubts about whether these software products offer quality training, being necessary to establish instruments that certify their characteristics or guide how to approach optimization to ensure success of this type of e-learning. This project proposes the Quality Evaluation of MOOC Information Systems with ISO/IEC 25010 through the construction of software Quality Model (QM) for MOOC to evaluate them in terms of their technological and pedagogical quality characteristics. Different technics are used in the methodology to lead to the construction and evaluation of the QM under certain quality requirements. The MOOC Information Systems Generic Architecture is built using the Discovering Hybrid ARchitectures by Modeling Actors (DHARMA) method based on the use of istar (i*) diagrams. The QM design uses the Individual Quality Model Construction (IQMC) method that has a set of steps specifically designed to support the construction of a QM and the selection of quality characteristics proposed in the standard catalog ISO/IEC 25010, which allows establishing an instrument with quality factors and measures that facilitate a systematic and practical evaluation of MOOC information systems by an evaluator. Finally, the QM is tested with the evaluation of two freely distributed MOOC platforms under the quality requirements of the University of Cuenca using the Weigths, Objectives, Rules, Mismatches, Selection (WORMS) method in the evaluation and selection of the platforms

    Evaluación de un modelo de calidad para objetos de aprendizaje basado en un modelo
    (2018) Solís Cabrera, Vanessa Alexandra; Carvallo Vega, Juan Pablo
    This work describes the process to create a quality model that allows the evaluation of Learning Objects (LO), considering technological and didactic aspects. To achieve this goal, existing quality models considering both aspects were identified and reviewed together with the concepts of LO and software quality. The i* notation was used to build a strategic dependence diagram (SD) describing the typical context of a Learning Object (context actors and their intentionality in relation to the LO) and the IQMC method to build the final quality model. Trazability among the strategic dependencies identified in relation to the external actors present in the context model and the characteristics and subcharascteristics included in the quality model described in the ISO/IEC 25010, is established. The objective is to make evident the relation existing among them and to identify in a systematic way, the quality properties that structure the first decomposition levels of the quality model under construction. These first levels are decomposed into more basic quality properties, using attributes included in the models identified in the literature review in addition to other models that have emerged in this study. Required measures have been associated to each quality property included in the quality model, in order to evaluate LO in an objective manner. To validate this work, the resulting quality model has been used to evaluate an existing LO.

    Identificación de elementos de modelos de contexto empresarial reusables que facilitan la construcción de modelos de contexto CM basados en i*
    (2016) Barreto Siavichay, Jorge Luis; Méndez Méndez, Mayra Paola; Carvallo Vega, Juan Pablo
    Nowadays, to know about the internal and external information developed in an enterprise, it is very important to take some strategic decisions, and as a consequence to keep stable businesses. The Systems Information Architecture design for a single enterprise, has a certain complex level according it grows, for that reason we had studied some business cases to obtain equivalent items and identify a reusable generic catalog for any company, no matter the goal of each one. For this, we describe the process, starting since the identification of actors, dependences, and the relation between them, until the polished and simplified of relevant data. According the process goes on, we can confirm every change in the catalog on each stage, obtaining generic elements that can be used as a template both technical and administrative staff.To resume the analysis, we generate some lists of identified synonymous, due to in an enterprise an element can be treated in different context but it can do the same purpose, in other words here we have repetitive elements. Finally, we propose two catalogs of elements, all treated as a single one. These catalogs include aspects commonly used and synthetized to be applied in any enterprise. They are two, one for each architectural approach; external and internal.

    Improving quality model construction through knowledge reuse
    (IBERO-AMERICAN CONFERENCE ON SOFTWARE ENGINEERING, 2015-04-22) Carvallo Vega, Juan Pablo
    Software quality models provide a framework to measure and evaluate software quality of software systems. They are the basis upon which classify requirements and may be eventually used to guide the quantification of these requirements, especially non-functional requirements. Lots of approaches for building quality models have been proposed in the last decades, but still their reuse along different projects is a challenge. In this paper we present several types of knowledge repositories and reuse processes to bridge this gap. The approach implements the idea of software factory and uses some well-known standards and notations like ISO/IEC 25010 as quality standard and the i? framework to codify knowledge patterns. We will illustrate how this reusebased approach helps in obtaining composite quality models for systems that integrate several software components with an individual quality model each.

    IStar in practice: On the identification of reusable SD Context Models elements
    (CEUR-WS, 2015-08-24) Abad Regalado, Karina Alexandra; Carvallo Vega, Juan Pablo; Peña, C
    Modern enterprises rely on Information Systems (IS) required both to support their operation and provide information required to endorse strategic decisions. Because of their increasing complexity, such systems are usually constructed by integrating software components of different nature and origins into hybrid systems, for which architectural design plays a fundamental role. However, far from simple, this task is usually cumbersome. In previous work we have addressed this issue and proposed a four steps, pattern-based approach, aimed to help in the solution of this problem. In first steps, patterns are described as Context Models, which include recurring elements (actors and dependencies) identified in several industrial cases. In this work we further address this issue and present an study aimed at the validation and extension of such patterns, and/or the identification of new ones, by reviewing recurring elements appearing in 29 semi-industrial IS architectural design processes.

    Miranda: a chatbot for supporting self-regulated learning
    (Springer Science and Business Media Deutschland GmbH, 2022) Narvaez Miranda, Edwin David; Pérez Sanagustín, Mar; Carvallo Vega, Juan Pablo; Maldonado Mahauad, Jorge Javier; Calle Morales, Darwin Mauricio
    Learning Analytics (LA) aims to understand and optimize the learning process in the environments in which they occur. It also offers opportunities for teachers to understand students’ behavior and promote the use of effective strategies that allow them to achieve their goals. Most of current solutions proposed in the literature for supporting students’ SRL are based on dashboards. However, if students do not interact with them, it becomes difficult to understand whether they have an impact in their self-regulated behavior. This demonstration, presents Miranda: A Chatbot that acts as a conversational agent to recommend and make suggestions on SRL strategies based on students’ the behavior. The first version of Miranda has been developed for Moodle, but it could be adapted to any other Learning Management System

    The MOOC-CEDIA observatory. Study of the current situation of MOOCs and recommendations to improve their adoption in ecuadorian universities
    (Universitätsverlag Potsdam, 2021) Samaniego Erazo, Gonzalo Nicolay; Valdiviezo Ortiz, Javier Alfredo; Maldonado Mahauad, Jorge Javier; Carvallo Vega, Juan Pablo
    In the last few years, an important amount of Massive Open Online Courses (MOOCS) has been made available to the worldwide community, mainly by European and North American universities (i.e. United States). Since its emergence, the adoption of these educational resources has been widely studied by several research groups and universities with the aim of understanding their evolution and impact in educational models, through the time. In the case of Latin America, data from the MOOC-UC Observatory (updated until 2018) shows that, the adoption of these courses by universities in the region has been slow and heterogeneous. In the specific case of Ecuador, although some data is available, there is lack of information regarding the construction, publication and/or adoption of such courses by universities in the country. Moreover, there are not updated studies designed to identify and analyze the barriers and factors affecting the adoption of MOOCs in the country. The aim of this work is to present the MOOC-CEDIA Observatory, a web platform that offers interactive visualizations on the adoption of MOOCs in Ecuador. The main results of the study show that: (1) until 2020 there have been 99 MOOCs in Ecuador, (2) the domains of MOOCs are mostly related to applied sciences, social sciences and natural sciences, with the humanities being the least covered, (3) Open edX and Moodle are the most widely used platforms to deploy such courses. It is expected that the conclusions drawn from this analysis, will allow the design of recommendations aimed to promote the creation and use of quality MOOCs in Ecuador and help institutions to chart the route for their adoption, both for internal use by their community but also by society in general.

    Towards the creation of a semantic repository of iStar-based context models
    (SPRINGER VERLAG, 2015-10-28) Abad Regalado, Karina Alexandra; Carvallo Vega, Juan Pablo; Espinoza Mejía, Jorge Mauricio; Saquicela Galarza, Víctor Hugo
    The System Architecture definition of the majority of organizations requires a deep understanding about its environment and organizational structure; nevertheless, the construction of such models is not an easy task because of the gap of knowledge and communication between the technical and administrative staff. The DHARMA method, which makes intensive use of the i* notation, propose a solution to that problem, supporting the Context Models construction. This paper presents an approach for annotating the i* models with semantic technologies, to support the search and generation of Context Models based on the knowledge defined in ontological models, allowing the creation of a Semantic Repository of Context Models, which will be used to discover relations between different i* models and extract patterns from them.
