New technology trends in education: Seven years of forecasts and convergence

Each year since 2004, a new Horizon Report has been released. Each edition attempts to forecast the most promising technologies likely to impact on education along three horizons: the short term (the year of the report), the mid-term (the next 2 years) and the long term (the next 4 years). This paper analyzes the evolution of technology trends from 2004 to 2014 that correspond to the long-term predictions of the most recent Horizon Report. The study analyzes through bibliometric analysis which technologies were successful and became a regular part of education systems, which ones failed to have the predicted impact and why, and the shape of technology flows in recent years. The study also shows how the evolution and maturity of some technologies allowed the revival of expectations for others. The analysis here, which focuses on educational applications, offers guidelines that may be helpful to those seeking to invest in new research areas.

Virtual Instrument Systems in Reality (VISIR) for Remote Wiring and Measurement of Electronic Circuits on Breadboard

This paper reports on a state-of-the-art remote laboratory project called Virtual Instrument Systems in Reality (VISIR). VISIR allows wiring and measuring of electronic circuits remotely on a virtual workbench that replicates physical circuit breadboards. The wiring mechanism is developed by means of a relay switching matrix connected to a PCI eXtensions for Instrumentation (PXI) instrumentation platform. The entire equipment is controlled by LabVIEW server software, in addition to a measurement server software that protects the equipment from hazard connections by verifying input circuit designs, sent by students, before being executed. This paper addresses other approaches such as remote labs based on Data Acquisition Cards (DAQs), NetLab, and RemotElectLab, comparing them with VISIR in order to emphasize its singularity. Topics discussed are as follows: the technical description, software, operation cycle, features, and provided services. In addition, the feedback received by students at several universities and the encountered drawbacks along with the proposed solutions are highlighted. The paper finally addresses the ongoing and future challenges within the VISIR community including its integration with Learning Management Systems (LMSs) and iLab Shared Architecture (ISA), its new hardware version release that is based on LAN eXtensions for Instrumentation (LXI), and its new open platform version that supports federated access.

Integration view of Web Labs and Learning Management Systems

The integration of Learning Management Systems and specific learning support applications known as Web Labs (remote and virtual laboratories) are the target of a new wave of service-oriented applications devoted to improving on-line learning experiences. Nowadays these solution works in a separet way therefore the students teachers, administration must log in different systems, the are not reusing services, etc. For these an other reasion in this paper we are focus in two topics. In one hand we describe a technique to present a web lab through a browser delivered by an LMS as a part of SCORM standard packaging. In other hand we describe a service-oriented architecture which allow integrating multiple LMSs (Moodle, .LRN, Claroline, etc.) with iLabs and multiples web an remote labs to supply the full functionality needed by educators

Expanding the Boundaries of the Classroom: Implementation of Remote Laboratories for Industrial Electronics Disciplines

It is apparent that implementation of practical sessions in engineering education paves the way for students to be familiar with instruments and, thus, with the industrial real world. In recent decades, the high cost and administration burdens of physical equipment have caused a significant decline in experimentation within engineering education. This situation has fostered the development and adoption of remote laboratories as a replacement. Recently, remote laboratories based on a large variety of technologies have been developed at multiple universities and adopted in industrial electronics engineering education. Furthermore, some of these laboratories are replicated at many universities. This was the commencement of a new mainstream that advocates a better remodeling of those laboratories to allow their allocation, sharing among universities, and their interoperable communication with other heterogeneous educational systems, e.g., learning management systems (LMSs). This article, on the one hand, reports on the design of the state-of-the-art remote laboratories for industrial electronics disciplines along with the cutting-edge technologies adopted. On the other hand, the article sheds light on the outstanding interoperable educational remote laboratories architectures, classifying them with regard to their exclusive features and provided services, and pointing out the limitations of each.

State-of-the-art remote laboratories for industrial electronics applications

There is no doubt that the implementation of practical sessions in engineering education paves the way for students to be familiar with the instruments and thus, with the industrial real-world. Moreover, they augment the learning outcomes by strengthening the understanding of scientific concepts and theories. Unfortunately, there exist a wide gap between the engineering educational curricula and the industrial real-world owing to the lack of experimentation availability. This is due to high cost and administration burdens that have hindered the adoption of practical sessions causing a significant decline in experimentation within engineering education. Recently, with the advent and exploitation of computer and communication technologies, remote laboratories have broadly proliferated among many universities. Remote laboratories provide on-line ubiquitous workbenches unconstrained by neither temporal nor geographical considerations and allow an interactive learning environment that maintains student attention. In this context, hundreds of remote laboratories for industrial electronics applications have been developed and numerous technologies have emerged in order to facilitate their construction and implementation. This paper reports on state-of-art remote laboratories for industrial electronics applications. and their design stages. The paper addresses many solutions in the development and the design stages, along with cutting edge technologies involved. This is in order to foster remote laboratories adoption within industrial electronics disciplines and hence, increase the industrial competencies in engineering education.

Remote labs as learning services in the educational arena

Technology-enhanced learning is not just interacting with learning objects. Physical labs are another useful resource in education, especially for engineering and science education. They are confined to the physical location they are bound to. It is obviously interesting for any learning process to be able to open up this access from remote locations in the same effective way as learning objects are accessed through a Learning Management System, taking advantage of the provided services, such as authentication, group building, etc.

Approaching hybrid wind-diesel systems and controller area network

High wind penetration hybrid wind-diesel systems have complex control requirements. The random nature of the wind, the cubic velocity to power relationship and the fast response of wind turbines make control goals like maintain system stability, and prescribed power quality levels, not easy to achieve. This paper deals with how to implement a distributed control system based on the controller area network (CAN) in hybrid wind diesel systems with high wind penetration. Firstly some introduction to hybrid wind-diesel systems is presented. Secondly two architectures for such hybrid systems are presented and studied mainly from the control point of view. This study concludes with a need of a distributed control, and the definition of some sensor and actuator nodes in the system. The CAN bus is used to close one of the several regulation loops presented. Some considerations about real time distributed control like clock synchronization among nodes when using CAN bus are presented. Finally some advantages of using CAN with such hybrid systems are outlined.

Generic integration of remote laboratories in learning and content management systems through federation protocols

Educational remote laboratories are a software and hardware tool that allows students to remotely access real equipment located in universities as if they were in a hands-on-lab session. Their integration in Content and Learning Management Systems (CMSs or LMSs) has been an active research topic for years, supporting mainly ad hoc solutions. A notable exception has been the use of federation protocols -commonly used for sharing laboratories from one university to other-, for actually sharing laboratories from a remote laboratory system to a C/LMS. This approach opened new doors in the simplification of the process, since it did not require the remote laboratories to make any type of change. The focus of this contribution is to provide a solution to decrease the number of functionalities required for creating an integration by providing a software component that reuses them. As shown in the contribution, this component has been implemented and two remote laboratory management systems (which provide access to multiple remote laboratories) are already supported, and a third one is under development. In the C/LMS side, all the LMSs supporting IMS LTI are supported, and HTTP APIs are provided for being supported by other systems. Indeed, the contribution describes its support in the Joomla CMS and in the Moodle 1.9 and dotLRN LMSs which do not support IMS LTI. The solution, called gateway4labs, is an open source initiative which targets to be used in production.

State of Art, Initiatives and New Challenges for Virtual and Remote Labs

Until a few decades ago, face to face classrooms and hand-on laboratories were the common solution for teaching theory and practice. But, new e-Learning tools have emerged and learning methodologies such as blended and distance learning have taken an important space in learning initiatives. Among them are virtual and remote Labs which provide student with a learning environment where can carry out the experiments through Internet and acquire the needed skills to develop his future jobs. This paper describes the importance of virtual and remote labs and their usage in learning scenarios.

Laboratory as a Service (LaaS): A model for developing and implementing remote laboratories as modular components

This contribution introduces a novel model, Laboratory as a Service (LaaS), for developing remote laboratories as independent component modules and implementing them as a set of loosely-coupled services to be consumed with a high level of abstraction and virtualization. LaaS aims to tackle the common concurrent challenges in remote laboratories developing and implementation such as inter-institutional sharing, interoperability with other heterogeneous systems, coupling with heterogeneous services and learning objects, difficulty of developing, and standardization.
