Providing equivalent learning activities with software-based remote access laboratories

Laboratory-based learning activities are important components of engineering and surveying education and it is difficult to offering practical activities to distance education students. Remote Access Laboratory (RAL) systems are widely discussed as learning tools to offer students remote access to rigs or hardware. In some disciplines laboratory activities are purely software based and RAL systems can be used to provide access to software. As part of a larger study into the transferability of the remote laboratory concept to non-engineering disciplines this project evaluates the effectiveness of RAL based software activities in supporting student learning is investigated. In the discipline of Surveying and Spatial Science, RAL technology is used to provide Geographic Information System software access to distance students. The key research question discussed in this paper is whether RALbased software activities can address the same learning outcomes as face-to-face practical classes for software activities. Data was collected from students' discussion forums, teaching staff diaries and teaching staff interviews. The project demonstrates that students undertaking learning activities remotely achieve similar learning outcomes than student in practice classes using the same software. Ease of system access and usability are critical and the learning activity needs to be supported by comprehensive learning materials. This research provides a clear case in which the use of RAL technology has provided inclusive educational opportunities more efficiently and these general results are also applicable to experiments that involve physical hardware

Robust Controller for Delays and Packet Dropout Avoidance in Solar-Power Wireless Network

Solar Wireless Networked Control Systems (SWNCS) are a style of distributed control systems where sensors, actuators, and controllers are interconnected via a wireless communication network. This system setup has the benefit of low cost, flexibility, low weight, no wiring and simplicity of system diagnoses and maintenance. However, it also unavoidably calls some wireless network time delays and packet dropout into the design procedure. Solar lighting system offers a clean environment, therefore able to continue for a long period. SWNCS also offers multi Service infrastructure solution for both developed and undeveloped countries. The system provides wireless controller lighting, wireless communications network (WI-FI/WIMAX), CCTV surveillance, and wireless sensor for weather measurement which are all powered by solar energy

Towards enhancing laboratory education by the development and evaluation of the "TriLab" : a triple access mode (virtual, hands-on and remote) laboratory

This thesis contributes to the general body of knowledge of research into engineering education. The main scope of the thesis is on enhancing laboratory education. There are three main types of laboratory: virtual, hands-on and remote. The hands-on lab is the oldest and most commonly used medium for experiential education in undergraduate degrees of science and engineering. The literature review of laboratory education has shown that hands-on labs suffer from many disadvantages, which can be overcome by utilizing hybrid laboratory structures that incorporate virtual and/or remote modes. The investigation into enhanced laboratory education is achieved via implementing new technical and pedagogical models of conducting laboratories. The technical model incorporates three access modes (virtual, hands-on and remote) to the laboratory experience in one software package called the TriLab. The TriLab concept has been applied to the Process Control Lab at the Chemical Engineering Department of Loughborough University and has been implemented using LabVIEW. The Joomla web content management system was used to develop an online portal for disseminating the remote component of the TriLab resulting in the first remote lab portal of Loughborough University and one of the few available in the UK. A pedagogical model of laboratory education based on Kolb's experiential learning theory and by the utilization of the TriLab concept is proposed. The model is built on a hypothesis, which states that the poor learning outcomes of hands-on laboratory sessions can be associated with poor activation of the stages of Kolb's experiential learning cycle. It has been proposed that access to a virtual lab in a preparatory session will play a role in activating the stages of Kolb's cycle. To verify this, educational experimentation procedures were designed and applied to two groups, control and experimental. Measurements via pre- and post-lab tests, marks for the laboratory report and the final exam of the module have been performed. The statistical analysis of the measurements has supported the stated hypothesis and solution proposal. The proposed pedagogical model is one of the few that provide a way of conducting laboratory education based on constructivist educational theories.

Collaboration in remote access laboratories

Collaboration in Remote Access Laboratories (RALs) is becoming increasingly important in both engineering and science education institutions, and with RALs service providers as an enabler to improving accessibility, reducing costs, and improving time-efficiency and student support. Yet research on the use of collaboration in RALs, in general, is limited. There is a lack of exploratory and empirical studies that provide an in-depth and holistic investigation of the design process and factors that influence the adoption of collaboration in RALs. Therefore, this study makes a significant and original contribution to current theoretical and practice knowledge with regards to pedagogical change in engineering education through the use of technology and remote access laboratories, where social constructivist practices are applied, in particular, engineering students undertaking LAB work in a different mode or approach to the traditional learning environment. This research employed a case study qualitative method with triangulation of data. Data were collected through observation of students working collaboratively in the trial of collaborative learning in RALs using the Voltage Divider Experiment task, and follow-up, in-depth interviews, with inductive analysis and activity recoding. The research explored Kagan’s PIES that relate to outcomes of the collaborative approach, Dillenbourg’s four elements of collaborative learning and Doolittle’s eleven principles of learning experience design as the theoretical bases of the collaborative pedagogical design of the RALs learning experience. While confirming their continued relevance to this context for learning three new principles were shown to be essential to facilitate and enhance contemporary learning in RALs. These included the need to build in the leadership of the collaborative learning experience, ensure task authenticity and participants acquisition of the soft skills, including interpersonal skills and teamwork, and their relevance to the workplace (employability). Additionally, this research highlighted how learning in RALs facilitates formative assessment that feeds forward to better support students’ learning where they need to communicate with each other during the LAB work collaborative learning experiences, thus drawing attention to the need for careful academic planning. The study also addressed the limitations of collaboration in RALs. It investigated the extent to which engineering students accepted collaborative learning in RALs as a workable alternative to traditional in-LAB work. It identified the key factors that are likely to influence the adoption of such pedagogical change, including factors to be considered when planning to adopt collaboration in RALs. This resulted in the development of an instructional framework for collaboration in RALs. It was concluded that collaboration in RALs has the potential to improve LAB learning through the availability of remote access, the facilitation of a sense of reality (comparable to traditional hands-on experience) and the opportunity for group work, and the need for skills that more closely related to those needed in students’ future workplaces
