Abstract
Remote Triggered Labs provides access to real experiments without time and location restrictions with necessary guidance required to perform experiments. Remote Triggered (RT) Labs have emerged as an alternative to real laboratories and have shifted the past pedagogy from student-centric to teaching-centric approach. Over the past decade several RT experiments have emerged in different parts of the world including those developed under Govt. of Indiaâ??s National Mission on Education through ICT as part of Right to Education (RTE) Program and various approaches have been implemented as to reinforce the use of Remote Labs in higher education. However, as the technology to build RT labs evolves there is a growing concern to adapt methodologies for developing scalable models of RT labs and introducing innovative ideas such as collaborative plans among universities within the RT labs framework. In this paper we propose a cloud based architecture for Remote Triggered Laboratory for Analog Communication. Cloud based models with their various characteristics e.g. - scalability, low cost and maintenance etc. provides several advantages to RT labs. Advanced web technologies are implemented to build up interface for teleoperation of high end instrumentation utilized in RT labs with interactive GUI design frameworks to deliver RT labs in a user friendly and more convenient environment.
Highlights
It has been shown that transition from a Faculty-Centric to a Student-Centric teaching approach can bring about many positive changes in the education system e.g. enhanced learning, independent thinking and creativity in students [1].Remote Laboratories, that favor the studentcentric approach, have clearly shown their academic usefulness [3] and have emerged as a possible substitute to real laboratories[4]
NetLabs, VISIR, and WebLabs have developed their remote labs that provide interface for electronics experiments based on analog circuits. iLabs [20] have developed a shared architecture using a service broker that provides a methodology to share remote labs experiments among campuses of different universities [19]. iLabs architecture is designed to focus on faculty-centric approach, our aim remains to move from faculty-centric approach towards a student-centric approach
Presented architecture is improvised as it uses the existing resources to build up a scalable model of remote labs using Elvis-DATEx bundle
Summary
It has been shown that transition from a Faculty-Centric to a Student-Centric teaching approach can bring about many positive changes in the education system e.g. enhanced learning, independent thinking and creativity in students [1].Remote Laboratories, that favor the studentcentric approach, have clearly shown their academic usefulness [3] and have emerged as a possible substitute to real laboratories[4]. Several other remote labs [21] have been developed that provide user interface for performing complex experiments and focus on various other areas [22] including Analog Communication [8]. Remote labs were developed to provide shared access of high-end instruments to multiple users simultaneously using internet. In this mode assuming that an experiment needs a one hour slot we can expect only a single user or a group of collaborative users will have access to the lab in that duration and no more than 24 such users would complete an experiment in a day Another approach is the ‘batch mode’ comprising of a queuing mechanism to handle multiple user’s requests simultaneously.
