Las relaciones profesionales informales, las que se superponen a las que imponen la estructura formal de una organización, son determinantes para que la colaboración, ya sea entre personas o entre equipos, sea efectiva, eficaz y eficiente. Las técnicas de Análisis de Redes Sociales (ARS) permiten dibujar el mapa de la red social de una organización, sus nodos, los enlaces que los unen y los influencers que las dinamizan. El principio aristotélico “el todo es más que la suma de las partes” adquiere, en este contexto, una dimensión real que, además, encuentra en el ARS su herramienta de prueba.

STEM (Science, Technology, Engineering and Math) education is currently receiving much attention from governments and educational institutions. Our work is based on active learning and video-based learning approaches to support STEM education. Here we aimed to increase student’s engagement through reflective processes that embrace video film-making, and subsequent on-line discussion and evaluation of those videos. We propose a group engagement score that takes into account both individual activity and similarity of participation, thus allowing corrective actions to be taken when unengaged students or groups are identified. We tested these ideas using our own social learning platform that combines the principal features of Social Networks with tools that facilitate collaborative learning design. This platform stimulates students’ learning by means of two main reflective processes: participatory production and peer-review. We evaluated this platform and the learning approach it supports in an Object Oriented Programming course and identified interesting differences between group engagement and video ratings. Our principal conclusion is that greater teacher and student awareness of the ongoing activities and group engagement are needed.

Mind the gap: Impact on learnability of user interface design of authoring tools for teachers

  • We study the learnability of educational authoring tools for preventing teachers’ rejection or abandonment.
  • We evaluate two interaction paradigms of authoring educational tools: menu-based versus direct-manipulation.
  • The interaction paradigm of the authoring tool has an important impact on the tool’s learning curve’s entry point.
  • A consistent interaction metaphor allows teachers creating educational activities smooth and fast.


Few teachers include information and communication technology in the classroom, despite their potential for increasing attention and motivation for students. Educational authoring tools are intended to turn teachers into designers and deliverers of technology-enhanced educational content, and increasing the adoption of these tools is a key element for speeding up this transformation. This paper emphasizes the importance of learnability for preventing rejection or abandonment by of such an authoring tool, and how acceptance is deeply affected by the interaction paradigm and the creation metaphor used in the tool. We present an analysis comparing two design paradigms: the widespread menu-based and choice-guided interaction paradigm versus a consistent metaphor with direct manipulation. The latter was implemented in DEDOS-Editor, a novel authoring tool that allows the creation of diverse educational activities that can be performed on different devices, such as PCs, digital blackboards, tablets, and multitouch surfaces. An experimental study shows the tremendous impact that interface choices have on the tool’s learning curve. The results provide the first mapping of the choice of a direct-manipulation interface and its effect on the learning curve’s entry point, as well as a consistent interaction metaphor with smoother and fast-growing learning curves. This allows users to complete more tasks and gain more knowledge through experience, in contrast to menu-based interfaces. The initial use of the tool is thus made easier for users with no experience or information about the tool, and the advantages of experience and expertise in facing new challenges are facilitating. This work also highlights the appropriateness of learning curves as a tool for measuring learnability.

British Journal of Educational Technology. Article first published online: 20 JUL 2015 (2015) DOI: 10.1111/bjet.12318 [download] (JCR, IF 2014: 1.394, Q1)

This paper describes two datasets extracted from a video-based educational experience using a social and collaborative platform. The length of the trial was 3 months. It involved 111 students from two different courses. Twenty-nine came from Computer Engineering (CE) course and 82 from Media and Communication (M&C) course. They were organised into nine interdisciplinary groups. Each group included three or four CE students and eight or nine M&C students. An additional group filmed the making of. This group has only M&C students. Four teachers supervised the trial. The total number of meaningful events was 2984.

Anonymized version of the activity dataset and profile dataset are publicly available.

Fair Trade metaphor as a Control Privacy Method for Pervasive Environments: Concepts and Evaluation

Abraham Esquivel, Pablo A. Haya and Xavier Alamán. Sensor 15(6), 14207-14229 (2015) doi:10.3390/s150614207 [download] (JCR, IF 2014: 2.093, Q1)

This paper presents a proof of concept from which the metaphor of “fair trade” is validated as an alternative to manage the private information of users. Our privacy solution deals with user’s privacy as a tradable good for obtaining environmental services. Thus, users gain access to more valuable services as they share more personal information. This strategy, combined with optimistic access control and transaction registry mechanisms, enhances users’ confidence in the system while encouraging them to share their information, with the consequent benefit for the community. The study results are promising considering the user responses regarding the usefulness, ease of use, information classification and perception of control with the mechanisms proposed by the metaphor.
