Validation of indicators for implementing an adaptive platform for MOOCs

2017

Personalization techniques are a classic solution recommended by many experts for improving learning. Information and communication technologies and online courses have helped reduce the difficulties teachers face with a diversity of student profiles and a large number of students in a classroom. When these factors are extreme, like in a Massive Open Online Course (MOOC), those techniques may be the solution. However, even the most sophisticated technologies have not solved all the challenges posed by personalized learning, and in cases where teachers are not skilled in the technology they must use, the adaptive systems have only complicated the implementation of online courses. Therefore, …

An Efficient NURBS Path Generator for a Open Source CNC

2014

In this paper a NURBS path generator (on the plane XY) is proposed to be developed for those CNC machine tools and robot which are Open Source or Opening Architecture. The goal is to use simple and efficient techniques to manufacture geometries which are very complex, whose main feature is the presence of free-form surfaces and contours. To reach this goal, the NURBS path generator has been optimized in order to enable the user to select among three different options to generate the tool path, using a specific parameter. The three options are respectively called “NURBS interpolation with constant increments of u parameter” (NICU), “NURBS interpolation with constant displacement increments b…

Do Individual Differences in Cognition and Personality Predict Retrieval Practice Activities on MOOCs?

2020

Online quizzes building upon the principles of retrieval practice can have beneficial effects on learning, especially long-term retention. However, it is unexplored how interindividual differences in relevant background characteristics relate to retrieval practice activities in e-learning. Thus, this study sought to probe for this research question on a massive open online course (MOOC) platform where students have the optional possibility to quiz themselves on the to-be-learned materials. Altogether 105 students were assessed with a cognitive task tapping on reasoning, and two self-assessed personality measures capturing need for cognition (NFC), and grittiness (GRIT-S). Between-group anal…

Entanglement control via reservoir engineering in ultracold atomic gases

2013

We study the entanglement of two impurity qubits immersed in a Bose-Einstein condensate (BEC) reservoir. This open quantum system is particularly interesting because the reservoir and system parameters are easily controllable and the reduced dynamics is highly non-Markovian. We show how the model allows for interpolation between a common dephasing scenario and an independent dephasing scenario by simply modifying the wavelength of the superlattice superposed to the BEC, and how this influences the dynamical properties of the impurities. We demonstrate the existence of very rich entanglement dynamics correspondent to different values of reservoir parameters, including phenomena such as entan…

Pulse radiolysis and theoretical investigation on the initial mechanism of the e-beam polymerization of epoxy resins. The results obtained on (phenox…

2007

Abstract The radical cation of (phenoxymethyl)oxirane ( PGE ⋅ + ) is generated by pulse radiolysis in dichloromethane solution and by direct action of radiation on the title compound. In the pure system its UV–vis spectrum is characterized by two bands at 340 and 430 nm, such that the electronic structure corresponds to a dipole bearing the positive charge on the phenoxy side. At the same time, the phenoxy-oxirane bridge is weakened. Then, the radical cation fragments into a phenoxonium ion and an oxyranylmethyl radical ( k PGE - fragm = 1.16 × 10 7 s - 1 ) . The latter immediately rearranges to an allyloxyl radical by ring opening. It is then conceived that the action of onium salts, as ra…

The impact of Open Access: benefits for individuals, organisations, and research progress

2017

In his presentation Mikael Laakso examines OA-related questions such as:What is the concept of OA benefits? What OA is most beneficial? What are some signs that OA is not fully leveraged currently? Presentation describes Open Access benefits for Individuals, Organisations, Universities, Libraries and Public & private sector.The overarching theme for the presentation is how OA is beneficial to research progress.

View of Open Government: in Italy and in the Sicilian Region

2017

The web, if used in connection with Open Government practices, it becomes anextraordinary controlling method not only to attack inefficiencies, corruption and badadministration, but also to promote transparency and develop participation practices.Complete transparency and open data represents lawfulness and efficiency outpostswhich are absolutely necessary to public administrations, because they are the newfrontier of citizenship rights and participatory democracy.This paper argues in favour of the anti-corruption provisions applications and thesubsequent applicator decree (Laws no. 190/2012 and 124/2015 and legislative decrees 33/2013 and now 97/2016) for the purposes of complete administr…

Supporting Learning Activities in the Health Sector through Open Data

2015

The growing availability of Open Data for educational purposes is playing a key role in shaping and influencing the development of the learning processes. At the same time, Open Data have a particular potential in the health sector so that the major healthcare organizations, universities, colleges, and medical schools are in the process of creating high quality 'Open' education & training resources and tools. However, in this growing world of open health resources for educational purposes, the task of finding the right material can become very difficult mainly when using a general purpose search engine like google. Thus, to overcome this problem and facilitate the search and learning ac…

Aula Virtual. Evolució del maquinari i millora de resultats

2009

Las Tecnologías de la Información y la Comunicación (TIC) han contribuido al desarrollo de plataformas e.learning de apoyo a los procesos de enseñanza-aprendizaje. Actualmente, la mayoría de universidades cuentan con algún tipo de sistema de gestión del aprendizaje (en inglés, LMS). El óptimo uso de estas plataformas requiere que integren las aplicaciones preexistentes de forma transparente. Esto se consigue con el uso de una arquitectura robusta. En este artículo expondremos la implementación y arquitectura del LMS integrado de la Universitat de València y la evolución de su hardware para adecuarse de manera óptima a las necesidades de la universidad.
