Item A Model for Online Assessment in Adaptive E-Learning Platform(Consejería de Educación, Ciencia y Tecnología de la Junta de Extremadura, 2005-06-07) Barbosa León, H.; Rego, H.; Moreira, T.; García-Peñalvo, F. J.In this article, we present some general aspects of the on-line assessment activity. For the pur-pose of this paper, we want to focus ourselves in the activity of evaluation that takes place in the e-learning process and discuss the importance of this action for each participant of the pro-cess. After that, we profile the desirable characteristics of an adaptive system and we describe the importance of the assessment activity. Later we present a proposal model for an adaptive assessment tool for an educational platform now in development.Item Psychiatric patients tracking through a private social network for relatives: development and pilot study(Springer, 2016-07) García-Peñalvo, F. J.; Franco Martín, M.; García-Holgado, A.; Toribio Guzmán, J. M.; Largo Antón, J.; Sánchez-Gómez, M. C.The treatment of psychiatric patients requires different health care from that of patients from other medical specialties. In particular, in the case of Department of Psychiatry from the Zamora Hospital (Spain), the period of time which patients require institutionalized care is a tiny part of their treatment. A large part of health care provided to the patient is aimed at his/her rehabilitation and social integration through day-care centres, supervised flats or activities. Conversely, several reports reveal that approximately 50% of Internet users use the network as a source of health information, which has led to the emergence of virtual communities where patients, relatives or health professionals share their knowledge concerning an illness, health problem or specific health condition. In this context, we have identified that the relatives have a lack of information regarding the daily activities of patients under psychiatric treatment. The social networks or the virtual communities regarding health problems do not provide a private space where relatives can follow the patient's progress, despite being in different places. The goal of the study was to use technologies to develop a private social network for being used by severe mental patients (mainly schizophrenic patients). SocialNet is a pioneer social network in the health sector because it provides a social interaction context restricted to persons authorized by the patient or his/her legal guardian in such a way that they can track his/her daily activity. Each patient has a private area only accessible to authorized persons and their caregivers, where they can share pictures, videos or texts regarding his/her progress. A preliminary study of usability of the system has been made for increasing the usefulness and usability of SocialNet. SocialNet is the first system for promoting personal interactions among formal caregivers, family, close friends and patient, promoting the recovery of schizophrenic patients. Future studies should study the network’s potential usefulness for improving the prognosis and recovery of schizophrenia.Item Estado actual de los sistemas E-Learning(Ediciones Universidad de Salamanca, 2005-06-01) García-Peñalvo, F. J.En este número especial de la revista Teoría de la Educación. Educación y Cultura en la Sociedad de la Información se abordan diferentes aspectos relacionados con los sistemas de formación electrónica, más conocidos como sistemas de e-formación o sistemas e-learning, desde distintos puntos de vista, que intentan reflejar el “mestizaje” científico que se presenta en este campo, y así dibujar un mapa actual del mismo, que incluya investigación y uso, con sus puntos fuertes y, especialmente, con sus áreas de mejora.Item Cultural values and technology adoption: A model comparison with university teachers from China and Spain(Elsevier, 2019-01-24) Huang, F.; Teo, T.; Sánchez-Prieto, J. C.; García-Peñalvo, F. J.; Olmos-Migueláñez, S.In this study, we investigated how certain cultural values influenced Chinese and Spanish university teachers' intentions to use technology. 426 Chinese university teachers and 404 Spanish university teachers participated in the study. The participants completed self-designed questionnaires based on Hofstede's cultural dimensions (individualism-collectivism, power distance, uncertainty avoidance and indulgence-constraint) as well as subjective norms and behavioural intention. We found consistent and significant relationships between subjective norms and behavioural intention in both the Spanish and Chinese samples. In addition, we found that the teachers' perceived cultural preferences influenced their subjective norms and intentions to use technology in both the Chinese and Spanish samples. However, the relationships between these variables were different in the Spanish and Chinese samples. In addition, we compared three models which were all theoretically reasonable to determine the model that best fitted the data. This study contributes to our understanding of how culture influences teachers' intentions to use technology in the contexts of Spain and China.Item Enabling adaptability in web forms based on user characteristics detection through A/B testing and machine learning(IEEE, 2018-02-14) Cruz-Benito, J.; Vázquez-Ingelmo, A.; Sánchez-Prieto, J. C.; Therón, R.; García-Peñalvo, F. J.; Martín-González, M.This paper presents an original study with the aim of improving users' performance in completing large questionnaires through adaptability in web forms. Such adaptability is based on the application of machine-learning procedures and an A/B testing approach. To detect the user preferences, behavior, and the optimal version of the forms for all kinds of users, researchers built predictive models using machine-learning algorithms (trained with data from more than 3000 users who participated previously in the questionnaires), extracting the most relevant factors that describe the models, and clustering the users based on their similar characteristics and these factors. Based on these groups and their performance in the system, the researchers generated heuristic rules between the different versions of the web forms to guide users to the most adequate version (modifying the user interface and user experience) for them. To validate the approach and con rm the improvements, the authors tested these redirection rules on a group of more than 1000 users. The results with this cohort of users were better than those achieved without redirection rules at the initial stage. Besides these promising results, the paper proposes a future study that would enhance the process (or automate it) as well as push its application to other eldsItem Towards a social and context-aware mobile recommendation system for tourism(Elsevier, 2017-06-11) Colomo-Palacios, R.; García-Peñalvo, F. J.; Stantchev, V.; Misra, S.Loyalty in tourism is one of the main concerns for tourist organizations and researchers alike. Recently, technology in general and CRM and social networks in particular have been identified as important enablers for loyalty in tourism. This paper presents POST-VIA 360, a platform devoted to support the whole life-cycle of tourism loyalty after the first visit. The system is designed to collect data from the initial visit by means of pervasive approaches. Once data is analysed, POST-VIA 360 produces accurate after visit data and, once returned, is able to offer relevant recommendations based on positioning and bio-inspired recommender systems. To validate the system, a case study comparing recommendations from the POST-VIA 360 and a group of experts was conducted. Results show that the accuracy of system’s recommendations is remarkable compared to previous efforts in the field.Item Learning Object Management and Evaluation: Working with IMS Specifications and Metadata on AHKME LOM Tool(INSTICC Press, 2006-04-11) Reo, H.; Moreira, T.; García-Peñalvo, F. J.AHKME e-learning platform’s main aim is to provide a system with adaptive and knowledge management abilities for students and teachers. This system is based on the IMS specifications representing information through metadata, granting semantics to all contents in the platform, giving them meaning. In this platform, metadata is used to satisfy requirements like reusability, interoperability and multipurpose. The system provides authoring tools to define learning methods with adaptive characteristics, and tools to create courses allowing users with different roles, promoting several types of collaborative and group learning. It is also endowed with tools to retrieve, import and evaluate learning objects based on metadata, where students can use quality educational contents fitting their characteristics, and teachers have the possibility of using quality educational contents to structure their courses. The metadata management and evaluation play an important role in order to get the best results in the teaching/learning process.Item e-Learning Platform Implementation - Learning Object an Learning Design Management Through Metadata Standards(Academic Conferences Limited, 2007-10-04) Rego, H.; Moreira, T.; García-Peñalvo, F. J.AHKME (Adaptive Hypermedia Knowledge Management E-learning) system main aim is to provide a modular and extensible system with adaptive and knowledge management abilities for students and teachers. This system is based on the IMS specifications, developed by the IMS consortium since 2001, that allow the representation of information through metadata, granting semantics to all contents in the system, giving them meaning. Metadata is used to satisfy requirements like reusability, interoperability and multipurpose. The system provides authoring tools to define learning methods with adaptive characteristics, and tools to create courses allowing users with different roles, student or staff, promoting several types of collaborative and group learning. The system is also endowed with tools to retrieve, import and evaluate learning objects based on metadata, where students can use and learn through quality educational contents taking into account their characteristics. Also teachers have the possibility of using quality educational contents to structure their courses and activities. In our system, metadata management and metadata evaluation play an important role in order to get the best results in the teaching/learning process. Regarding the mechanics of the system, we have divided it in four different subsystems. These subsystems are in constant communication receiving feedback between them in order to adapt to students, teachers and different kinds of learning contexts. In order to develop our system we have started to analyse several current existing e-learning platforms and systems to identify strong points and weaknesses, so we could try to overcome these weeknesses with our system. We have also analysed several standards and specifications to find the one that best fitted our needs in order to help us reach our objectives. In this paper we will focus on the two subsystems that make possible the management and evaluation of learning objects through metadata described by the IMS specifications.Item Personal Data Broker Instead of Blockchain for Students’ Data Privacy Assurance(Springer, 2019-04-01) Amo, D.; Fonseca, D.; Alier, M.; García-Peñalvo, F. J.; Casañ, M. J.Data logs about learning activities are being recorded at a growing pace due to the adoption and evolution of educational technologies (Edtech). Data analytics has entered the field of education under the name of learning analytics. Data analytics can provide insights that can be used to enhance learning activities for educational stakeholders, as well as helping online learning applications providers to enhance their services. However, despite the goodwill in the use of Edtech, some service providers use it as a means to collect private data about the students for their own interests and benefits. This is showcased in recent cases seen in media of bad use of students’ personal information. This growth in cases is due to the recent tightening in data privacy regulations, especially in the EU. The students or their parents should be the owners of the information about them and their learning activities online. Thus they should have the right tools to control how their information is accessed and for what purposes. Currently, there is no technological solution to prevent leaks or the misuse of data about the students or their activity. It seems appropriate to try to solve it from an automation technology perspective. In this paper, we consider the use of Blockchain technologies as a possible basis for a solution to this problem. Our analysis indicates that the Blockchain is not a suitable solu-tion. Finally, we propose a cloud-based solution with a central personal point of management that we have called Personal Data Broker.Item Addressing Fine-Grained Variability in User-Centered Software Product Lines: A Case Study on Dashboards(Springer, 2019-04-01) Vázquez-Ingelmo, A.; García-Peñalvo, F. J.; Therón, R.Software product lines provide a theoretical framework to generate and customize products by studying the target domain and by capturing the commonalities among the potential products of the family. This domain knowledge is subsequently used to implement a series of configurable core assets that will be systematically reused to obtain products with different features to match particular user requirements. Some kind of interactive systems, like dashboards, require special attention as their features are very fine-grained. Having the capacity of configuring a dashboard product to match particular user requirements can improve the utility of these products by providing the support to users to reach useful insights, in addition to a decrease in the development time and an increase in maintainability. Several techniques for implementing features and variability points in the context of SPLs are available, and it is important to choose the right one to exploit the SPL paradigm benefits to the maximum. This work addresses the materialization of fine-grained variability in SPL through code templates and macros, framed in the particular domain of dashboards
