    This paper describes the work carried out by the Makerere University iLabs Project Team, hereafter referred to as iLabs@MAK. The procedures followed to develop Online Laboratories using the National Instruments Educational Laboratory Virtual Instrumentation Suite (NI ELVIS II™) platform is discussed. The laboratories were developed based on the Massachusetts Institute of Technology (MIT) iLabs Shared Architecture (ISA), a model that provides highly reliable generic services independent of the experiment domains. Modifications were made to the ELVIS version 1.0 code to introduce desired functionalities. Experiments were selected from three fundamental courses offered in the Department of Electrical Engineering, Faculty of Technology, Makerere University. Starting with the rationale for development of iLabs in specific courses, the paper presents the methods employed and the results obtained from the various experiments. Experiences and perceptions from over 300 students who performed the experiments were captured as a core aspect of the Research.

    An Online Digital Filters and Sound Effects Laboratory Utilizing NI SPEEDY 33 and LabVIEW DSP Module
    (New Generations, 2011) Kyesswa, Michael; Mbajja, Amru; Tumusiime Asiimwe, Arthur; Mwikirize, Cosmas; Musasizi, Paul Isaac; Tickodri-Togboa, Sandy Stevens; Katumba, Andrew; Butime, Julius
    There has been an increasing use and application of the internet due to the advances in technology. At Makerere University1, the internet has been used by students to remotely access and share scarce laboratory resources using the iLabs platform. This paper presents the design and implementation of an on-line laboratory that supports experimentation in Digital Filters and Sound Effects based on digital signal processing techniques. In the laboratory design, the National Instruments Signal Processing Educational Engineering Device for Youth (NI SPEEDY 33) is programmed to carry out the different processing on an applied signal at the input using the LabVIEW DSP Module. The input is an audio signal and the output is a modified audio signal whose wave form is be displayed at the client. The online laboratory is developed using the interactive iLabs Shared Architecture that allows more student interaction with the hard ware.

    Online Laboratories: Enhancing the Quality of Higher Education in Africa
    (Conference of Rectors, 2011) Akinwale, O.B.; Ayodele, K.P.; Jubril, A.M.; Kehinde, L.O.; Osasona, O.; Akinwunmi, O.; Tumusiime Asiimwe, Arthur; Mwikirize, Cosmas; Musasizi, Paul Isaac; Tickodri Togboa, Sandy-Stevens; Katumba, Andrew; Butime, Julius; Nombo, Josiah P.; Baraka, Maiseli M.; Teyana, Sapula; Alfred, Mwambela J.; Musa, Kissaka M.
    Online laboratories have been adopted by the Obafemi Awolowo University (OAU) - Nigeria, Makerere University (MAK) - Uganda and the University of Dar-es-Salaam (UDSM) -Tanzania to enhance the delivery and quality of higher education. Utilizing the Massachusetts Institute of Technology (MIT) iLabs Shared Architecture (ISA), grant-related teams at each of the three universities partook research into the development of online laboratories (iLabs) to support Science and Technology curricula. This has provided students with a low-cost, flexible, convenient and reliable experimentation platform. The iLab-Africa project has also opened up specific beneficial areas viz.: collaboration between universities, staff-student exchanges between these universities and MIT, funding opportunities, the possibility of collaboration between universities in different countries on the use of scarce laboratory equipment, and the collaboration of students between universities in different countries on specific laboratories. This paper discusses the application of iLabs in improving the teaching and learning processes at each of the partner Universities and highlights the offshoot advantages arising from the same. It thus lays a case for adoption of the technology throughout Africa to support curricula and promote inter-institutional collaboration.
