Abstract/Description
Hands-on laboratory experiences are a key part of all engineering programs. Currently there is high demand for online engineering courses, but offering lab experiences online still remain a great challenge. Remote laboratories have been under development for more than 20 years and are part of a bigger category, called online laboratories, which includes also virtual laboratories.

Show moreHands-on laboratory experiences are a key part of all engineering programs. Currently there is high demand for online engineering courses, but offering lab experiences online still remain a great challenge. Remote laboratories have been under development for more than 20 years and are part of a bigger category, called online laboratories, which includes also virtual laboratories. Development of remote laboratories in academic settings has been held back because of the lack of standardization of technology, processes, operation and their integration with formal educational environments. Remote laboratories can be used in educational settings for a variety of reasons, for instance, when the equipment is not available in the physical laboratory; when the physical laboratory space available is not sufficient to either set up the experiments or permit access to all on-site students in the course; or when the teacher needs to provide online laboratory experiences to students taking courses via distance education. This dissertation proposes a new approach for the development and deployment of online laboratories over online platforms. The research activities performed include: The design and implementation of an architecture of a system for Smart Adaptive Remote Laboratories (SARL) integrated to educational environments to improve the remote laboratory users experience through the implementation of a modular architecture and the use of context information about the users and laboratory activities; the design pattern and implementation for the Remote Laboratory Management System (RLMS); the definition and implementation of an xAPI-based activity tracking system for online laboratories with support for both centralized and distributed architectures of Learning Record Stores (LRS); the definition of Smart Laboratory Learning Object (SLLO) capable of being integrated in different educational environments, including the implementation of a Lab Authoring module; and finally, the definition of a reliability model to detect and report failures and possible causes and countermeasures applying ruled based systems. The architecture proposed complies with the just approved IEEE 1876 Standard for Networked Smart Learning for Online Laboratories and supports virtual, remote, hybrid and mobile laboratories. A full set of low-cost online laboratory experiment stations were designed and implemented to support the Introduction to Logic Design course, providing true hands-on lab experience to students through the a low-cost, student-built mobile laboratory platform connected via USB to the SARL System. The SARL prototype have been successfully integrated to a Virtual Learning Environment (VLE) and a variety of configurations tested that can support privacy and security requirements of different stakeholders. The prototype online laboratory experiments developed have contributed and been featured in IEEE 1876 standard, as well as been integrated into an Industry Connections Actionable Data Book (ADB) that was featured in the Frankfurt Book Fair in 2017. SARL is being developed as the infrastructure to support a Latin American and Caribbean network of online laboratories.

A comprehensive engineering education, per ABET, requires an equal emphasis on both lecture and laboratory components. The laboratory experience builds and establishes a foundation of skills and experiences that the student cannot obtain through any other means. The laboratory must use modern, pertinent methods and techniques including the use of appropriate tools. This is especially true when it comes to test equipment. Engineering students require and deserve training on and access to modern test equipment in order to obtain better career opportunities. However, providing access to modern and relevant labs requires a significant budget commitment. One way to extend current budgets is to adopt the growing concept of “remote labs.” This approach allows higher utilization of existing (and costly) equipment, it improves an institution’s Return on Investment (ROI), and also can be used to meet the needs of students’ complicated schedules, especially in the case of a “commuter campus,” where a majority of students live off campus. By developing remote labs, both the institution and the students benefit: Institutions increase equipment utilization, and utilize space, budgets and support personnel more efficiently. Students can access a lab whenever and wherever they have internet access. Finally, academic integrity must be protected to ensure the potential of remote laboratories in education. This Thesis presents a design and implementation plan for a low cost Logic Design laboratory infrastructure built and tested over 3 years by over 1,500 Logic Design students; a design and implementation of the infrastructure to include the ability to measure using remote test equipment; and the design of a case (3d printed or laser cut) to encapsulate a USB enabled micro-controller; and a scheme to ensure the academic integrity is maintained for in-person, hybrid and fully online classes.
